Kiyotaka Ayanokōji/Plot

Plot
During the bus trip to school, he witnessed Kikyō Kushida pleading Rokusuke Kōenji to give up his seat for an older woman, but to no avail. Watching the scene, he commented on the situation as he noticed another girl looking on with a cold stare. Shortly after, the students arrive at the school where Kiyotaka talks with the other girl who inquired as to why he looked at her as he stated he saw a similarity between them in the bus incident. She told him not to compare them as she chooses not to involve herself in such a trivial manner, while he internally noted that she is worse than him.

He attended the opening ceremony where he was surprised to learn he was classmates with the girl from earlier, named Suzune Horikita, who said it was a bad coincidence after being seated next to each other in class 1-D. As most of the students introduced themselves, Kiyotaka evaluated most of their personalities before being asked to introduce himself. His undecided thoughts caused him to awkwardly introduce himself, though he did give his name and stated that he hopes to be friends with the class. His speech was applauded by a few classmates, but he was mocked by Suzune. Shortly after the introductions finished the class met their teacher, Sae Chabashira, who told them about points and how the school operates.

Days went by, and Kiyotaka is still unable to make friends but did find an associate in Suzune, who sits next to him in class. He later met Kikyō, who is one of the few to interact with Kiyotaka apart from Suzune. She asked for his help in befriending Suzune herself, and he reluctantly agreed to take her to a café for the meetup. After class the next day he asked Suzune to accompany him, as it was a girls café and he felt too scared to go along. Upon arriving at the packed place, a table opened up for them to sit, where they were joined by Kikyō, although that caused Suzune to leave due to her uncovering their plan.

After a month passed, the class was told they wouldn't get any more points after losing them all, although put their effort in the upcoming test to gain more. Kiyotaka was invited to lunch by Suzune, and while he was doubtful on her intentions, he went and treated himself to lunch at her expense. To his mild dismay, Suzune uses this as an opportunity to force him into helping her reach Class A bringing up his supposed conspiring with Kikyō as a means to get an agreement. Reluctant, he agrees and is tasked by Suzune to gather up the more idiotic students for a study group. He was annoyed that the first girl to give him her number was blackmailed him. He tried to get Kanji Ike, Haruki Yamauchi and Ken Sudō to join but they all refuse; however, it took bringing Kikyō into the plan and Suzune herself reaching out to Ken for everyone else to agree on joining. Despite this, Suzune's condescending attitude causes them to leave and taking the risk of failing. Kiyotaka brought this up to Suzune who paid it no mind and said what they did had no repercussion on her.

One night, while he was out getting a drink, he found Suzune about to be assaulted by her older brother, Manabu Horikita, but quickly intervened by grabbing the man's hand admonishing his acts as he demanded him to release her. He was told by Suzune not to get involved as he noted on the sincerity in her tone, which caused him to release Manabu before avoiding the latter's strikes with ease and pushing him back. Kiyotaka was asked by Manabu in which fighting arts he practised, but he replied with a vague answer. Manabu proceeded to recall him from his test scores and implied that Kiyotaka is hiding his intelligence, but he called it a coincidence as Manabu left the area.

Suzune thanked him, but he shrugged it off, and when she complimented his fighting skill he stated it was nothing special, just piano and tea ceremony lessons as to which she called him out on this contradictory statement. He was then questioned by Suzune if her brother's statement about him scoring half of what he should have made was true, but he again provides a vague answer. Suzune remarked that everything about him is a mystery, to which he replied asking if the study group was finished, in which she confirmed. Kiyotaka asked her if she ever wondered whether it was her distant and cold behaviour that got her placed in D-Class, but she couldn't answer it.

When Suzune decided to disband her study group, Kiyotaka decided to use the school rules to his advantage. With the help of Kikyō, he requested an upperclassman to give him answers for an old test in exchange for points while also having Kikyō use her charm to convince him further to lower his payment. Not liking the thought of attention, Kiyotaka has Kikyō take credit, and a majority of the class passed except Ken, who would be expelled. Kiyotaka then used his points to bribe the teacher to overturn this decision, to which she agreed but only after Suzune helped out with the payment. Because of this, Ken was saved, and the teacher told them to keep making things interesting for her since they could advance to Class A which is something nobody else did something in the history of class 1-D.

During a celebratory party at his room, Kiyotaka was asked by Kikyō if he had a hand in stopping Ken's expulsion as the latter and his friends listened to see if this was true. However, Kiyotaka passed the credit to Suzune, much to her dismay. Later that night, he went to return a phone that Kikyō left behind, however stumbling upon her hidden personality, cursing Suzune out loud. After being spotted, Kikyō threatened him with rape charges after she placed his hand on her breasts. After asking whether she can trust him, he swore not to tell anyone about this as she reverted to her cheerful personality and walked off.

Kiyotaka soon made another acquaintance with Honami and helped her in facing a love confession from her friend by giving her the courage, to be honest after she requested that he pretended to be her boyfriend. When this was done, he gained her gratitude, and she paid him back by helping in proving the innocence of Ken after he was accused of attacking three boys of class 1-C.

He and Kikyō soon meet Airi, who witnessed the brawl but stated she didn't want to get involved, though after her camera broke, she requested their help in getting it repaired. Kiyotaka then helped her with two matters, first with the broken camera and then by telling her not to burden herself with the current event. Those encouraging words later motivated her to change her mind and help with the hearing. At the hearing, he noticed Suzune was in fearful silence due to her brother's presence and helped her to return to her senses and called for Airi, who provided her evidence. After the hearing ended for the day, he spoke to Airi, comforting her just as Manabu appeared and stated he expected more from the hearing since he saw Kiyotaka was present. Kiyotaka shrugged it off and once more avoided Manabu's strike with ease while affirming his belief in Airi.

After that, Kiyotaka and Suzune went to the area where the fight occurred, and Suzune devised a plan to get the trio of class 1-C to withdraw their complaint, which had Kiyotaka borrow points from Honami to buy cameras. With that done, he headed to class and spoke to Airi promising her help in the future before going off to put the plan into action. The procedure was successful as Suzune and Kiyotaka have the students believe that the Student Council President knows the truth, causing them to withdraw their complaint. Soon afterwards, Kiyotaka spoke with Honami and with her help saved Airi from being assaulted by a crazed stalker. After the stalker was apprehended by security, Kiyotaka made another acquaintance in Airi.

He later spoke with Ken who told him how the students of Class C withdrew the complaint. Kiyotaka gave Suzune credit for saving Ken, who believed it as he happily went off to practice. Kiyotaka later met with Manabu and his secretary in the hallway. Manabu explained the recent events and asked if this proved Airi was telling the truth before he congratulated him on his victory, but Kiyotaka once again gave Suzune all credit for the act. Glaring at Kiyotaka, Manabu had asked Tachibana if they had an opening for a secretary on the Student Council, to which she confirmed. Manabu offered the position to Kiyotaka, while Tachibana questioned his intentions only to be silenced by a gaze from him. He repeated this offer for Kiyotaka to join the council; however, he rejected it in favour of living a regular school life. Manabu accepted this choice for now but told him not to disappoint him as he and Tachibana walked off.

Kiyotaka soon met Suzune and walks with her in the rain with their umbrellas, and when they reach the street, she accuses him of manipulating her into carrying out false evidence to get the complaint withdrawn, he denies this and she brings up the promise he made to help her reach Class A as he reminds her that she had forced him to do so. He tries to walk off, but she stops him and presses him for the reasons of his actions as she wants to know if she can trust him as he explains that he simply wants to live a peaceful life, but she states that he wouldn't have helped if that were true. Kiyotaka states he was looking out for a friend, but she disregards this and pressures him into revealing his motives. Kiyotaka briefly reflected on his past before he stated he would help her in reaching Class A but sternly told her never to try prying into his past again.

During summer break, he was a part of a group of boys who planned to peep on the girls changing room under the codename "Argos-4", though he didn't want to participate. Knowing that the boys would proceed behind his back, he decided to join but enlisted Suzune's help to sabotage the plan. He invited her to the pool and told her of the boys' plan, and asked her to steal the memory cards from the cameras at the right time. He later invited Airi the pool as well to have fun, and they met up with some students of class 1-B. At the outing, Kiyotaka tried to use the event as a way to get Suzune to lose her cold demeanour and associate with people no matter how tough it was to get through to her. When the boys plan to hit a problem, they signalled Kiyotaka for help, and he had Suzune perform a speech that distracted everyone. This allowed the boys to safely abort the plan, while Suzune collected the cards. Kiyotaka thanked her for the help before asking if she had fun in which she gave a negative reply. He followed up by pushing her into the pool, and she did the same though everyone else joins in afterwards. He watches as she plays with the class before he was splashed by Airi as she sinks in the water out of embarrassment when he stared at her. That night, he sent Suzune a picture of her with the other students at the pool.

On the school cruise, he was summoned by Sae; he went to the theatre where she informed him of an unknown man who wanted Kiyotaka to be expelled. She promised to protect him but only if he started working his way up to A-Class, but he refused to comply, causing her to promise that he will be expelled, which in turn caused him to grab her by the collar and warn her not to manipulate him. She was unfazed by his actions and told him to choose between leaving or ascending to A-Class. After that, he went to the bow of the ship, where he contemplated whether he should reveal his talents just to stay in school.

While relaxing in his room, he is visited by Yōsuke Hirata who invites to an outing with his friends, but he turns it down. Yōsuke soon reveals his true intentions were for Kiyotaka to get Suzune to work with him as Kiyotaka gives him an unsure answer before he leaves.

He later spent his time with the 3 Idiots of D-Class, being confused over why they were excited about Kanji asking Kikyō if he can call her by her first name. He was even more confused when an excited Ken asked him what Horikita's first name was, giving him the answer before going for lunch. At the restaurant, Kiyotaka noticed how out of element they were as Ken grabbed one student for insulting them, leaving Kōhei Katsuragi to break up the fight and the boys leaving the area, Kiyotaka taking caution of Kōhei. At night, he approached Airi while she was on the deck of the ship (who was seen practising to ask him out), his presence startled her and caused her to become flustered. After being asked if he heard her, Kiyotaka denied listening to her and asked what it might've been about. Airi instead told him that she needed his help in becoming friends with the class, where she is seen to be still nervous around them. He agreed to help her, saying that it was nothing special, as she became elated and grabbed his hand out of gratitude. However, the moment between the two ceased when Kikyō appeared, and Airi quickly excused herself by leaving.

Kiyotaka talked with Kikyō and noticed that her bubbly nature almost made him forget about the hidden persona he saw the other night. When he tried to leave, Kikyō stopped him, shifting back to her darker personality to continue talking. She inquired if he was nervous and wary being alone around her, to which he confirmed, as she went back to her other personality, and told him that she just gets lonely when left all alone. She tried to tell him something else but decided not to go through with it and left while he was put off by her actions.

The ship arrived at the island and was told that they are meant to survive on the island for a week to achieve bonus points.

After receiving the provisions, class 1-D moved out while Suzune asked about Kiyotaka's dreams after graduation, earning yet another vague answer. After Yōsuke asked for everyone to gather supplies for camps, Kiyotaka volunteered, telling a surprised Suzune its best to not stick out. He was grouped with Airi and Rokusuke, though he lost track of the latter when he escaped through the trees, presumably ditching the test then.

When they discovered a point spot, Kiyotaka hid with Airi as he felt someone was coming and covered her mouth just as Kōhei Katsuragi and Yahiko Totsuka appeared. Kiyotaka overheard them talking and noticed a glimpse of A-Class' leader card, but knowing he was a cautious man, he deduced Yahiko was the leader. After the two left, he released Airi and apologized for his actions, but she was seen still heavily blushing and squirming on the ground, nervously mumbling that it was fine. He and Airi investigate the spot, and with this, he decided to change his strategy to guess the leaders of the classes. After returning to camp, he relayed this information to Yōsuke and soon asked for Suzune to join him in gathering firewood, but she refused. He later went with Airi and Haruki who told him that he sought to win over the latter by being a nice guy. The trio then found Mio Ibuki bruised and laying against a tree as Haruki tried to approach her, but Kiyotaka stopped him, sensing something was up but relents, and they took her back to the camp. Once at camp, they discussed what to do about her before learning Rokusuke Kōenji dropped out of the test which would deplete some of the class' points.

The next day, Kiyotaka and Suzune went on a reconnaissance to see what the situation was like at the other class camps. The first camp they found was class B. They had their spot set up near a waterfall and operated similarly like theirs. Suzune was impressed when she witnessed how disciplined and coordinated everyone was. A quality that D class lacks. Honami modestly explained the difficulties she and her class faced at first, and how they eventually overcame it together. When Suzune and Honami finished affirming their relation, a student interrupts their conversation and asks if there was something he could do to help out around camp. Honami assigns him to help out a few other students, he thanks her politely and makes his way. Seeing that he was somewhat distant from the rest, Suzune asks Honami out of curiosity. Leading them to learn that, he is actually from class C, but was kicked out due to a falling out.

Kiyotaka internally deduced that the student was a spy sent from class C and chose not to identify class B's leader due to their class alliance and that the leader would be guessed anyway. The pair then left to scout class A's camp which was in a cave. When they arrived, they hid in the bushes while they observed class A's movements from a distance. Seeing that Suzune wasn't going to take the initiative because she was intimidated by the best class, Kiyotaka takes a stand and tells her that he is going to them. Suzune hesitates at first, however after Kiyotaka reasonably reasons against her emotions, she regains her usual confidence. Following his lead to approach them. They were unknowingly speaking to class A's leader for entry to their camp. When Suzune was about to take a look beyond the draped curtains at the entrance of the cave, she was stopped by Kōhei. He summons his security force and warns her that her 'right to enter' was an intrusion on their territory and that might lead to a start of a war.

With that, Kiyotaka and Suzune decided to leave class A alone and depart for class C's camp which they found at a beachside. Under Kakeru's leadership, the pair discovered that class C had spent all their S-points on buying luxury items the other class was scrimping on. Kakeru told them that they did this, knowing that they will not be penalized even if they had spent all of their test points. Kakeru mocks class D for sacrificing themselves for the test. Suzune and Kiyotaka witness how Kakeru treats his classmates like slaves. As such, Kakeru had punished Mio for being disobedient and critical of his leadership while Suzune spoke with Kakeru, Kiyotaka spotted a two-way communicator and deduced Kakeru was the leader before he and Suzune left the area. He told Suzune what Kakeru's endgame was similar to what Rokusuke did to return to the cruise. That night, Kiyotaka sneaked into the girls' tent at the class D camp and searched Mio's bag for her phone. He discovered her camera and sabotaged it as he figured that she was a spy.

On the fourth day, class D did more survey to find out who the class leaders are. Kiyotaka and Airi were gathering supplies when he asked her if she wanted to stay in a pair with him, to which she confirmed though apologized for dragging him down in the search. He soon asked her if she was afraid if people started talking to her about them, as she told him that she didn't care about that, explaining that she was down on the school trip at first due to not having friends, but now was glad that she came. She then admiringly looked at him, stated regrettably that she wanted to have her camera so that she could take a great picture of him. He and Airi met Honami and Ryūji Kanzaki at class C's camp only to find out that everybody except Mio had withdrawn from the test. He then asked them about Arisu Sakayanagi and Kōhei Katsuragi, he learned of the two were leaders of the class, but their ideals collide with one another. On the fifth day, Kei Karuizawa found out that her underwear was stolen. The girls of class D had Yōsuke conduct a bag search, and Haruki found it in Kanji's bag. Kiyotaka believed he didn't take it, but Kanji quickly planted it on him, he was forced to hide it just as Yōsuke did a pat-down search on him and he prepared for the worse. To his surprise, Yōsuke reported that he does not have it. Unsurely, Kiyotaka confronted Yōsuke and asked why he covered for him as Yōsuke asked if he took them, but Kiyotaka confirms he did not, and Yōsuke decides to take the underwear knowing that his reputation would be damaged the least for being the culprit because Kei is his girlfriend. He then asked for Kiyotaka to find the real thief which he agrees.

The day after the underwear scandal, the girls demanded the boys be separated from them. They made Yōsuke stand guard, with Suzune intervening by stating that since he is a boy himself, he needed to be watched as well. The girls agreed but were unsure of who else to pick as Suzune nominated Kiyotaka as another guard since he didn't seem like the type to peep on girls. While some of the girls noted on his lack of prominence in the class, they nevertheless accepted him as a guard as he complained about being the last resort, but still accepting the request. As he worked, Kiyotaka was approached by Mio, who asked if he believed she stole the underwear since she was an outsider. However, he replied he knew she didn't do it and trusted her, much to her surprise and joy as she thanked him for believing her. After he finished working, he met Suzune and asked her why she made him a guard, as she stated she needed him as an incentive as Yōsuke couldn't be trusted. They talk about secretive people for a while as Suzune stated, unlike Kiyotaka and others she has no such side. He soon asks her how long she was going to pretend to be healthy while she asked how he knew she was sick in the first place as he mentioned her behaviour since the test started.

Shortly after, he goes back to the spot where he found Mio and discovers a communicator like Kakeru confirming her as a spy. To put a plan in action, he promises Haruki that he'd give him Airi's email if he did him a favour. He, Suzune and Kanji tried to catch some fish but to no avail as they only caught one. Kiyotaka then spoke with Suzune discussing the leader key card as he had seen it on Kōhei and wanted to match them. Once he saw it, Kiyotaka confirmed they didn't match, but Haruki places mud on Suzune after noting on their closeness, which earned him a flip from Suzune but Kiyotaka caught him. This would soon prove to be part of his plan as he had Suzune show him the card so Mio would be tempted to steal it since her camera was destroyed. By having Haruki drop mud on her, Kiyotaka gave Suzune a reason to go to the waterfall so she temporarily relieves herself of the card so that Mio could steal it.

While the class was distracted by the fire he started, Kiyotaka put his plan into action to help D-Class win the test. After Mio stole the card once she defeated Suzune, Kiyotaka found an unconscious Suzune injured after her fight with Mio and took her to a tree before she awoke. They talk where he discovered her reasons for reaching Class A and noticed she wanted allies before he implores her to withdraw from the test, but she refused out of pride though she fell unconscious. He carried her and returned Suzune in her deteriorating condition to the teachers to go back to the ship, officially causing her to drop out. He assumed the position as the class leader, foiling class 1-A and class 1-C's plan so they'd incorrectly guess D-Class' leader as still being Suzune.

When the test finished the following day, D-Class cleaned up camp as Kiyotaka spoke with Airi for a while and approached Yōsuke. He gives the sulking Yōsuke a list of the other class' leaders and the latter puts down the names on the list. Later on, D Class is declared the winner of the test due to correctly guessing the leaders of classes A & C, leaving class B's out because he wanted to remain friends with them. Upon returning to the ship, Kiyotaka is questioned by Suzune on how the class passed the test, and he told her of his plan and how he outsmarted the other classes with various tactics, which left her in astonishment at his intellect as she tries to ask about his motives before the class arrives. It turns out he told their class the credit was all Suzune's, quickly gaining her popularity. Kiyotaka then met with Kikyō, who asked whether he would prefer being with Suzune or her, to which Kiyotaka said he didn't know, leaving her dissatisfied with the answer.

As this happened, Kiyotaka was contacted by Sae Chabashira who requested he met with her again at the theatre. Once there, Kiyotaka's plan is complemented by her, and she revealed it was indeed his father who requested Kiyotaka be expelled though he also said Kiyotaka would leave of his own accord soon enough. Sae soon asked him on what he planned to do now, to which she receives a vague answer, she goes amused at his response.

He wandered the ship just as Suzune confronted him once again and he calmly stated that she needed allies, having noticed she finally changed her anti-social behaviour. After he confirmed he did everything to help her, she gets flustered and blushed before begrudgingly thanking him while stating that she will see him as an ally though she warned Kiyotaka not to get too friendly with her as all she wanted is to reach A-Class.

While she went on about this, Kiyotaka internally noted that he doesn't truly acknowledge her, Kikyō and Yōsuke as allies but merely pawns in helping him to win. As it turned out, Kiyotaka's time in the White Room made him more than willing to do anything to accomplish victory even if it meant using people to believe that all of humanity was nothing but tools. He ended his monologue, stating that all that matters is him winning in the end.

Volume 4
After completing the grueling Island survival special test, yet another special test is announced back on the cruise ship. For this special exam, Kiyotaka is placed in the Rabbit Group, alongside Kei Karuizawa, Hideo Sotomura and Teruhiko Yukimura. Prominent members of the rabbit group from other classes are Class B's representative Ichinose Honami and Class C's Ibuki Mio. The following day after the announcement of the exam, Kiyotaka meets with Horikita in the morning to discuss the exam, where they are interrupted by Kakeru Ryūen who shows suspicion that Kiyotaka abilities isn't average as it seems, implying that his loss in the island exam is due to someone working in the shadows behind Horikita.

As the exam continues, Kiyotaka starts having doubts about Karuizawa's personality through her interactions with Manabe and Ibuki who had already been determined as the person who stole her underwear in the Island survival exam. Moreover, despite having Hirata as a boyfriend, she is openly flirting with the Class A student Machida Kōji. During some down time during, Kiyotaka receives a message from Sakura telling him she would like to meet him, as he approaches the meeting point she overhears her trying practicing asking someone out on a date. Kiyotaka pretends not to hear what she said and that puts her at ease, as they proceed to discuss about the exam. Following this encounter, Yamauchi approaches Kiyotaka from behind and asks for advice on how to approach Sakura. Kiyotaka proceeds to advise him to work hard and produce results for this exam as Sakura and Yamauchi are grouped together. As he gives this advice he thinks that even if Yamauchi fails and loses points, he will be able to make use of his failure in the future.

After one of the meetings of rabbit group, Kiyotaka and Yukimura notice that the Class C girls lead by Manabe in the rabbit group except Ibuki were acting strange as they follow Karuizawa outside their usual meeting room. They watch as Manabe's group, take Karuizawa to a emergency stairwell where they proceed to shove her into the wall, and begin to bully her. Yukimura wants intervene before it escalates but Kiyotaka stops him as he believes stopping the bullying from occurring now will not guarantee that it will stop in the future. As the bullying begins, Karuizawa's usual strong facade drops as she begins begging for them to stop while holding her head in her hand and shaking violently before finally ceasing to move at all as if she had totally given up. As Kiyotaka begins to finally understand Karuizawa a little better after observing her, Yukimura intervenes too early before he can gather more information. As Kiyotaka threatens to call more people, Manabe and her friends leave before promising to make Karuizawa apologize to Rika who Karuizawa had previously wronged. With the girls gone, Karuizawa's haughty facade returns as she tells the two guys to get lost and not tell anyone what they had seen.

After this encounter Kiyotaka approaches Chabashira sensei to confirm that at this goal anything can be bought with points. As she confirms this, Kiyotaka tells her he will have a request for her sometime in the future. With some understanding of Karuizawa's situation, he follows Hirata out of thier shared room at 2am in the morning who is going to meet Karuizawa as Kiyotaka suspects. He informs Hirata that he is somewhat aware of the situation which prompts Hirata to allow Kiyotaka to follow him to meet Karuizawa. When they meet Karuizawa is surprised to see Kiyotaka there but proceeds to ask Hirata for help in dealing with Manabe. Hirata declines saying that he won't hurt others for any reason which makes Karuizawa angry who then storms off. As Kiyotaka quietly observes, he puts together the pieces of the puzzle and realizes that their relationship has been fake the whole time, Karuizawa is similar to a parasite who can't live without having someone to protect her which is why she uses Hirata and flirts with Machida to gain protection within their rabbit group. Hirata reveals the reason he actually wanted Kiyotaka to come along was so he could do something about the situation as there were some things he wasn't willing to do. Furthermore, Hirata continues to explain about Karuizawa's past and a little about his own past, which leads to Kiyotaka having some doubts about Hirata's real personality but he does not press the issue. Throughout their conversation Kiyotaka continues to pretend that he is trying to get close to both Hirata and Karuizawa as per Horikita's ideas. However, he has other plans for Karuizawa. Before they end the conversation, Kiyotaka passes a piece of paper to Hirata which prompts a conversation about the VIPs of class D.

During one of the intervals, Kiyotaka has already made plans for Karuizawa. One the one hand using Hirata to lead her to lower decks of the cruise ship where there are no cameras, and on the other he a message to Manabe using an account that is not registered to his ID obtained from Chabashira, telling her that he will help her get revenge on Karuizawa. When all of the girls arrived at the lower deck. Kiyotaka is hiding below as he observes the scene of the Class C girls physically bullying Karuizawa before determining that not much physical harm is being done, he leaves to let Karuizawa be bullied by Manabe and the others. He returns sometime later, when Manabe and the others leave to check on Karuizawa, he reveals that he knows all about her past as a victim of bullying the past that Karuizawa has tried so hard to protect from being revealed and proceeds to push her into the wall. Karuizawa continues to put on her strong facade but Kiyotaka continues to push her limits by sexually harassing her to see how far she is willing to go to protect her secret and her place in the school. When she doesn't resist, he decides that she will be very useful to him. As she continues to submit to his advances, Kiyotaka presses her to reveal more about her past bullying which she tells him willingly, however, he realises that she is still hiding something, and presses her further, from her actions Kiyotaka finds a scar on her body. By showing her the darkness in his past through his eyes, Karuizawa begins to understand Kiyotaka a little better. After Finally obtaining all of her secrets, Kiyotaka then changes his attitude and promises to protect her in Hirata's place instead promising to do a much better job than he can in exchange for her cooperation. He shows her a picture of Manabe bullying her in the stairwell, which he plans to use to stop Manabe from bullying her again. He also tells her that he plans to use her to win the special exam for their group.

A final meeting of the exam, the rabbit group decides to that everyone should show the emails on their phone to prove who is the VIP. As everyone shows the email they received from the school, Yukimura is revealed to have the email that shows that he is the VIP, as everyone decides that he is the VIP, Ichinose makes a call to Kiyotaka's phone. The phone Yukimura is holding rings showing Ichinose as the caller. Revealing that Kiyotaka and Yukimura had switched phones. Yukimura apologizes to everyone for trying to trick them hopes that everyone will wait to reveal the VIP together instead of betraying them as it's decided by the group that Kiyotaka is the VIP. A little after the rabbit group meeting ends, a notification comes that the rabbit group exam is over meaning someone betrayed the VIP. Ichinose and Kiyotaka who are both still in the meeting room discuss what happened, with Ichinose revealing she suspected that Kiyotaka and Karuizawa had switched SIM cards and she was the VIP. Kiyotaka inquires why she didn't reveal her suspicions if she had known, she replies that since Class A was most likely to betray them due to their in fighting, it would be beneficial to let them guess wrong. Kiyotaka decides that he needs to reevaluate Ichinose. At the end of the exam, Kiyotaka discusses the results with the leaders of Class D, Hirata, Karuizawa and Horikita, which once again Ryūen interrupts and informs them he had complete control of this exam and that Class D should watch out as they were his next target.

Volume 4.5
During the summer holidays of the first year, as Kiyotaka transfers a large amount of points to Sudō. Sudō asks Kiyotaka for help in asking Horikita to go see a fortune teller that has specially come to Keyaki Mall for the summer holidays. Despite his best effort and Horikita having some interest in fortune telling, she turns him down. Being slightly interesting in fortune telling, he goes down to Keyaki Mall by himself where he bumps into Ibuki Mio. Unfortunately, the fortune teller only accepts pairs, therefore Ibuki and Kiyotaka who both have come along are denied. Ibuki discusses some of her interest in coming to see the future telling with Kiyotaka but since both can't get their fortune told they leave for the day. The next due to his talk with Ibuki, Kiyotaka decides to go back to Keyaki mall, where he once again meets Ibuki at the fortune teller, this time they both decide to go in as a pair and get their fortune told. They are left with a warning that to not take detour on the way back, due to the crowds at the elavator then both decide to go to an elevator further away which ends up trapping them as it stops mid-way. Kiyotaka calls Kōhei Katsuragi for help which arrives a little after as Ibuki and Kiyotaka are freed from the elevator.

Katsuragi's connection with Kiyotaka is revealed in a flash back where Kiyotaka and the idiot Trio are looking for a gift to buy for their classmate Inogashira. They spot Katsuragi who is buying a gift that is rather girly and the idiot trio believe that he is buying a gift for his girlfriend. The idiot Trio pressure Kiyotaka into finding out the identity of Katsuragi's supposed girlfriend. Kiyotaka waits around the main road to catch Katsuragi. Along the way, he is spotted by Manabu Horikita, Suzune's older brother and the student council president as well as his secretary Akane Tachibana. Manabu talks about the recent developments of Class D in the island exam and suspects Kiyotaka is behind Horikita's sudden status as the class leader. While Kiyotaka denies this Manabu does not believe him and even invites him to be the Vice-President of the student council, which surprises Tachibana. Kiyotaka rejects his offer, which further surprises Tachibana. Tachibana wonders if Manabu means for Kiyotaka to be the vice-president when Nagumo becomes the president but states that normally there are two vice-presidents in the student council. However Tachibana statesthat there is no way Nagumo would allow that. After the conversation with Manabu, Kiyotaka spots Katsuragi leaving the dorm and headed in the direction of the school. Realizing that the only reason to wear your school uniform would be to visit the school grounds which was required. Kiyotaka is unable to follow as he is in his everyday clothes. Kiyotaka waits for Katsuragi to return from school to question him on who the gift is for, but does not get an answer. Reporting this to the Ike, he realizes that he could be buying the present for himself to make himself feel better for not getting any present for his birthday. Feeling sorry for him the idiot trio and Kiyotaka decides to celebrate his birthday with him. Kiyotaka discovers that the present is actually for Katsuragi's twin sister who is not at this school, Katsuragi has been visiting the student council to receive permission to send her a gift but is his request is denied as it is against the school rules. Kiyotaka proposes using Sudō who is leaving campus for a basketball match to send the gift to Katsuragi's sister in exchange for 100000 private points, while Kiyotaka receives 5000 points as the intermediary. As Sudō successfully completes the task, the idiot trio and Kiyotaka celebrates Katsuragi's birthday with him.

Another incident that occurs during the summer involved Horikita who finds herself in a spot of trouble as her hand gets stuck in her water bottle while she is cleaning, due to the stoppage of water across the dormitories, and the convenience store. Horikita is unable to get her hand out of the bottle. Finally giving up and needed help, she calls Kiyotaka. Who suggest asking someone for water such as Ike or Sudō. She refuses, Kiyotaka next suggests Sakura or Kushida. Due to the bad relationship between Kushida and Horikita chooses Sakura to ask for help. Sakura doesn't immediately reply and Horikita is left with the choice to travel to Keyaki Mall to get water. After failing to get dormitory without being seen, due to the intervention of Koenji who calls Kiyotaka elevator boy when they meet in the elevator. As well as meeting Kushida along the way out, Horikita gives up and returns to her room. Thankfully by then Sakura had replied and the case of the stuck hand is resolved.

Following the events of the cruise, Yamauchi asks for Kiyotaka's help in confessing to Sakura. Yamauchi passes a love letter to Kiyotaka to pass to Sakura for him. Kiyotaka asks for Kushida's help to call Sakura out and hands her the letter. While she misunderstands that the love letter is not from him, he clears it up by repeated that he is just the messenger. Sakura is disappointed that it is not from Kiyotaka, seeing that Kiyotaka says it could be from someone she likes but she accidently blurts out that the chances of that is now impossible. Sakura manages to guess who the love letter is actually from based on Yamauchi's behaviour. Later that night, Sakura and Kiyotaka briefly talk about what she should do, Kiyotaka talk about them both having 0 zero experience in love and that reassures her, she also asks Kiyotaka to meet with her before she is to meet with Yamauchi. The next day at the meeting place, she tells Kiyotaka that she is going to reject Yamauchi, which Kiyotaka completely expected but it was important for her to say it outloud. As Kiyotaka is about to leave, Sakura asks for him to stay as she wouldn't be able to speak if he wasn't there. Kiyotaka complies with her request. While Yamauchi is somewhat bothered by his presence, Kiyotaka's words leave no room for him to protest. Yamauchi confesses his feelings, but is rejected by Sakura who apologises and leaves Kiyotaka and Yamauchi alone. Yamauchi confesses that he probably didn't really like Sakura and just thought she was cute and would be great to date. He apologises for getting Kiyotaka roped up in this business, while Kiyotaka replies that it's all right and thinks that Yamauchi has grown from this experience.

As the summer holidays comes to a close, the idiot trio along with Kiyotaka, Kushida, Horikita and Sakura head to the pool for some final summer activities. There they meet Ichinose and some of her classmates. Furthermore they are introduced to Nagumo a 2nd year member of the student console who started from class B like Ichinose but has reached already reached class A. Inspired by Nagumo's volley ball match. Ichinose challenges the class D students to a volley ball game with the losers having to pay for the winners lunch. Class D composed of everyone except Sakura win the match and are treated to lunch by class B. After lunch, everyone decides to leave the pool while Kiyotaka stays behind to find Karuizawa who is waiting for him. They discuss his plans from now on, Kiyotaka tells Karuizawa that he plans to expel someone in the near future, which surprises her. He tells her he may want to expel the 3 students who know her students, if not them then someone from another class, if another class is not possible someone useless from their class. Karuizawa, calls Kiyotaka a terrible person as he remembers what he did to her on the cruise ship, he thinks she is probably not wrong. They discuss about telling his plans to Hirata but Kiyotaka says he can't be trusted yet, because of his past. Karuizawa tells him, that he is definitely not normal which Kiyotaka readily denies and she calls him a liar. As they are about to leave, Kiyotaka notices Karuizawa hesitate, she tells him that he should know that changing in front of other people is difficult for her. Kiyotaka thinks that if he can get her to swim today that would be good. She refuses him when he asks her to swim asking why does she have to let him see her in a swimsuit. Forcing the issue, he orders her to swim which she relunctantly obeys. As she takes off her rash guard and places it on the chair she doesn't turn to face Kiyotaka due to scar on her body. Without warning Kiyotaka then grabs Karuizawa's arm and throws her into the pool. As he reaches out to Karuizawa with his hand, she pulls him into the pull with him. The play around in the pool as the life guard comes over to get them to leave as the pool is closing. As they play in the pool like children, Kiyotaka thinks it was worth it to even see a Karuizawa laughing for even a moment.

In side story of Ike, Yamauchi and Sudō's summer holiday. It is revealed that the idiot trio forced Kiyotaka along with their plans to peep on the girls changing room which was connected to the male changing room using a remote control car and a camera. This is the reason, Kiyotaka asks Karuizawa to meet him a day before going to the pool so he can have her interfere with the idiot trios plans. Once everyone had finished changing, Karuizawa entered the changing room and found the remote control car, replacing the memory card in the camera with a blank one so the idiot trio would have no footage of any of the girls changing.

Volume 5
Kiyotaka gathers with Horikita, Hirata and Karuizawa for lunch, to discuss the results of the previous cruise ship special exam. Together, they manage to decipher the way in which the VIPs were chosen for the exam. They wonder why Ryūen who had figured out all the VIPs made a mistake in guessing one of the groups. Hirata and Horikita guesses that maybe someone in Class C betrayed Ryūen, while Kiyotaka does not offer a theory he does not believe that anyone betrayed him.

Later that day during afternoon classes, a new event is announced with class points and private points on the line, the Annual Sports Festival where the students across all levels compete in sports events to determine the winner. For this year's sports festival, Class D and A and placed in the red team while B and C are placed in the white team. With the announcement over, Sudō comes over to Horikita to propose his idea that they should select their best athletes for each event to win as many as possible. Kiyotaka thinks that this would be a way to win but would leave some of the class unsatisfied because students who place in the bottom ten will receive minus points in the subsequent exam, causing worry for the students who are weaker academically. 20 mins after the announcement, the class gathers in the sports hall and meets the other classes of the red team, the leader of the red team, Class 3-A's Fujimaki. At the hall, Kiyotaka also spots a long girl sitting in a chair holding a cane, Katsuragi explains that she is Arisu Sakayanagi. The school provided her a chair due to her difficulty walking. Horikita asks Kiyotaka if there is anyway for them to win this "special exam". However Kiyotaka points out that no teacher and no documents have mentioned that this is a special exam and even the 3rd years seem like they are treated it like a sports festival rather than an exam. Horikita disagrees and says since points are on the line it is the same as a special exam. They are unable to reach an agreement. After the assembly in the sports hall, Kiyotaka on the way back to the dormitory alone he bumps into Chabashira sensei, who question him whether he as a plan for the sports festival, he has he doesn't have any plan at all this time.

Over the next few weeks, in preparation for the Sports festival, the class is given free time to plan their strategy. Horikita comes up with a strategy where they should let the most athletic students get first choice in whatever events they think they can win to take as many podium finishes as they can, her strategy involves pairing the weaker students with the stronger students which the diminishes weaker student's their chances of winning any event, which leaves the academically weak students and physically weak students in danger of receiving penalties in the next exam. While Kiyotaka doesn't necessarily think that the strategy is wrong, he uses Karuizawa to propose another strategy, sending her a message during the class discussion. Telling her to oppose the current strategy and get Kushida's opinion. Thinking on her feet, Karuizawa says they shouldn't eave the weaker students behind, and proposes a multi-pronged approach where the strongest aims for 1st place but leaving the 3rd place or 2nd place open for those who have a chance to attain that position also participate instead of just selecting the athletically strong students take all the top spots. Kushida who is put into the spotlight by Karuizawa agrees with both opinions and the class is divided, hence Hirata puts it to a class vote. Horikita's strategy wins 16-13 votes as Kiyotaka abstains from voting. As the plans are decided, school ends. Kiyotaka sends Karuizawa a message signaling her with a glance, but she leaves the classroom regardless, thinking she didn't get his message Kiyotaka leaves as well but finds Karuizawa waiting by the stairwell for him asking him if he wanted to talk to her. They discuss the strategy for the class, even though Karuizawa agreed with Horikita's strategy she came out with a good compromise and despite being put on the spot by Kiyotaka, who thinks she did a good job. As they part, Kiyotaka thinks that he has managed to get a very useful pawn to use in Karuizawa due to her ability to read the atmosphere and act accordingly.

As class D prepares for the sports festival, everyone's abilities are measured to see what events they would be best at. During the grip strength test, Kiyotaka asks Sudō what the national average is and is told that it is about 60, hence when it is his turn to take the test he ensure's that he gets 60.6 kg in grip strength. To his surprise he finds out that Sudō got the average wrong and it is closer to 50. Due to the mistake, by the measurement, Kiyotaka is now the second strongest in grip strength in the class hence is selected to participate in the 4 way Tug of Wag event along with Sudō, Hirata and Miyake. Another event that Kiyotaka is chosen to participate in is the scavenger hunt race which was decided by rock-paper-scissors. For events that all students must participate in such as the 3 leg raced, Kiyotaka is paired with Hirata. With the selections and teams decided for all the events. Class D begin practicing for the sports festival. During one of these practices, Horikita performs poorly in the 3 legged race with her partner Onodera who is one of the fastest students in Class D. Kiyotaka reasons that because Horikita is unwilling to match Onodera pace they aren't performing well. In order to show her the importance of team work. Kiyotaka pairs up with her, and moves so fast that she cannot keep up, causing Horikita to almost fall down if not Kiyotaka catching her. Kiyotaka hopes she has learnt her lesson from their 3 legged race.

As the preperations carry on, Kiyotaka meets with Horikita and Kushida to discuss scouting out the competition. Horikita at first refuses because Kushida and Kiyotaka would be enough but once Kushida is gone, he tells Horikita that although he has no proof tells her that Kushida most likely betrayed the Class and told Ryūen that she was the VIP in the previous exam. This causes her to agree to scout out the competition together. Meeting the next day, Kushida, Horikita and Kiyotaka are watching the soccer club and with Kushida's extentive network is able to point out everyone's names.

Finally, the day of the sport festival arrives. Kiyotaka begins the festival by carefully not getting any of the top spots but also avoiding all the bottom spots. Ryūji Kanzaki approaches Kiyotaka asking him why he is holding back especially since there wasn't any real need to and since Ichinose told him that Kiyotaka was fast. Kiyotaka continues his act although Kanzaki does not believe him. As the festival unfolds, Kouenji doesn't want to participate so he pretends to be sick, angering Sudō who almost starts a fight but is stopped by Hirata. Furthermore, Ryūen uses dirty tactics that could have injured people during the tug of war and pole toppling event which futher sours Sudō's mood as the day goes on. Kiyotaka also begins to notice a pattern emerging as Horikita is repeatedly forced to compete with the same person 2 people from Class C, Yajima and Kinoshita who were faster than Horikita due to due experience in track and field, leading him to suspect it was not a coincidence. This culminates in an accident where the Kinoshita collides with Horikita and both girls are injured. Although Kinoshita is unable to continue competing, Horikita can still compete albeit not at her best due to being slightly injured as Kiyotaka notices during her 3 legged race with Kushida where they both end up in last place. Class C continues their relentless attack on Horikita in the Female Calvary Battle as all the Class C cavalries surround Horikita, although Karuizawa tries to assist, she is stopped by Ichinose who prevents her from Horikita leading ultimately leading to Class D and As defeat. During the guys turn to compete in the calvary battle, Ryūen once again uses dirty tactics, this time applying hair wax onto the headbands so they are much harder to grab off their heads. His tactics greatly anger Sudō who is all but ready to get into a fight. Moreover, due to continued loses, Sudō is increasingly taking out his frustrations on his classmates. Karuizawa comes over to speak him Kiyotaka, after the battle expressing concerns about the developments. She also uses his first name for the first time even ommiting honorifics which startles Kiyotaka although he decides now isn't the time to think about it. They talk about their selections being released and the existence of someone betraying them comes up. Karuizawa asks Kiyotaka what he is going to do to help them win, but he says he is going to do nothing and everything is happening as he has foreseen. Before she can ask more, Sudō returns to the class tent and wants to go and confront Ryūen. By this point the pressure of being leader overwhelms him as his classmates point out how poorly everything is going and how he needs to calm down and act appropriately when the pressure boils over, he hits Hirata who is trying to mediate. Chabashira sensei who has arrives asks what's wrong but Hirata covers for him, finally fed up Sudō just leaves when Horikita can't look at Sudō.

Once Sudō leaves, Class D is put in a terrible position as Sudō is supposed to participate in many of the selection events. Kiyotaka finds Horikita and gives her advice on what she can do now, which is to find Sudō and bring him back. Horikita doesn't want to and Kiyotaka believes it's because she doesn't understand that Sudō has feelings for her. He talks about how Ryūen crated his plans to defeat her and especially Sudō mentally. While she still resists, Kiyotaka harshly tells her, she as she is now is totally useless and she should go and do something useful. She is injured and simply praying to recover is not good enough. Kiyotaka leaves her to make her own decisions after giving her his advice, while thinking that what Horikita needs is to feel defeat and be reborn. Following his conversation with Horikita, Kiyotaka eats lunch with Karuizawa and Hirata as they discuss the existence of the spy in their class, Hirata says that it's a delicate matter and shouldn't be raised casually so as to not disrupt the class. They also discuss what to do know that Sudō is gone.

After lunch, Kiyotaka participates in the Scavenger Hunt race but ends up last due to having to find things like 10 Friends and the person he likes which results in him wasting too much time changing what he has to find. Next he takes over Sudō's place in the mixed 3 legged race while Kushida takes Horikita's place. As they both prepare for the race, Kiyotaka tells Kushida she was the one who leaked Class D selection list to Class C, they discuss how the spy could have done it. Kiyotaka reasons that the spy asked Chabashira sensei to see the list, when Kiyotaka suggests asking Chabashira sensei if there was anyone who asked to see the list, Kushida drops her facade and tells Kiyotaka that he isn't some normal person. Kiyotaka asks why she did it, and she replies that she wants to expel Horikita Suzune and it willing to do that even if it means Class D loses.

By the time Horikita and Sudō return, it is time for the final event. As Miyake sprained his leg in the earlier 200m race, Kiyotaka offers to replace him. While Kushida replaces Horikita. Kiyotaka is chosen as the anchor, as he is waiting for the baton to reach him, Horikita Manabu is the anchor for his class and he proposes that Kiyotaka and he should race. even at the cost of 2nd place. Manabu doesn't start running when he receives the baton but waits for Kiyotaka to receive his from Kushida. As they run, Kiyotaka runs as fast as he can although as he reaches the final bend he thinks he should speed up. In the end, due to both Manabu and Kiyotaka's speed, the runner in front of Kiyotaka trips over surprise causing Kiyotaka to fall as well hence he doesn't win the race. Having gone all out for the first time, many people come over to expresses their surprised, the first of which is Karuizawa who disappears as more of their classmates arrive. The results are released and class D is last placed.

At the end of the day, Kiyotaka meets with Sakayanagi at the entrance of the school who wants to talk to him. Before he goes to talk to her, Kiyotaka sends a recording to Ryūen exposing his plan to cause Horikita to fall down during one of the events. He sends it to Ryūen who is threatening Horikita with false evidence that Horikita tripped Kinoshita on purpose. After they introduce themselves Sakayanagi reveals that she has known him for 8 years and 243 days. Which Kiyotaka says is not possible because he doesn't know her, but one-sidedly knows him from the "White Room". Kiyotaka is surprised she knows something about his past. She also reveals that she knows that he has been acting behind the scenes of his class. She declares that it is her duty to defeat the fake genius that is Kiyotaka, and doesn't intend to reveal his past to anyone.

Volume 6
As the sports festival comes to a close, the seasons change and the school welcomes Autumn. As the students gather in the sports hall, the first sign of changes appears in the form the change in Student Council members. With Manabu Horikita stepping down as president and Miyabi Nagumo taking over as the new student council presidents. Nagumo vows to break down the traditions that the school has during his term and introduces several changes such the increasing the length of his term as student council president to last until he graduates instead of until the following October. Alongside these changes, Kiyotaka expresses that many of his personal relationships are also about to change. With some people growing further apart and others growing closer. Other changes Kiyotaka notices is the changes in Sudō's attitude during class especially after the sports festival. Sudō appears to be paying more attention during class and even taking notes, noting that Horikita checking them after may be a large influence on him. He thinks that Sudō will be a great resource for the class moving foward. During lunch, Kiyotaka is eating alone when Horikita comes to make fun of him for being alone. She teases him about Ike and Yamauchi who have seemed to have been inviting Kiyotaka less and less to their gatherings. He thinks that in fact they have stopped inviting him along at all and have now taken to inviting Sotomura out with them. She also mentions that it can't be helped as now due to his race with Manabu, the 2 guys are don't feel like he is below average like them due to his speed. As she leaves him alone to eat lunch. Kiyotaka thinks that he respects Horikita for all the time she spends alone.

Kiyotaka also notices that Karuizawa is still in the classroom, when he notices Karuizawa's gaze and thinks that she wants to talk but realises she doesn't when she averts his gaze quickly as if to tell him she didn't mean to look at him. As she leaves the classroom, he notices that her skirt is about 1-2cm shorter than normal. When Kiyotaka is finally alone in the classroom, his classmate Satō whose given name he doesn't know due to how little they interact comes up to him and asks for some of his time to talk. Satō asks him if he has a girlfriend and he tells her no, thinking that lying in this situation would just make him be liked even less. Finally realising her intentions, his first thought is whether this was a trap set by someone. As they exchange numbers because Satō want's to start with being friends first. Kiyotaka is curious about her sudden interests and asks her about it. She tells him that because of the sports festival, she finds him very cool. While he ponders what he should do, he thinks that Satō is nothing but a classmate to him and he understands a little better how Sakura felt when she was confessed to by Yamauchi. After Kiyotaka parts ways with Satō, he runs into Katsuragi who wants to talk to him. Katsuragi expresses his surprise at his race during the sports festival but Kiyotaka doesn't say much. They end up discussing about Ryūen and how he is a common enemy for all the classes. Kiyotaka counters with how Katsuragi was the first person to work with Ryūen, which Katsuragi now regrets. Kiyotaka asks if Katsuragi wants him to pass on the messsage to Horikita still feigning ignorance, but he receives Katsuragi's warnings regarding Ryūen and promises to pass the message to Horikita. Later that evening, Kiyotaka receives a call from Karuizawa which surprises him. She calls and demands to know happened with Satō in the afternoon, informing him that she knew Satō was going to confess. She wants to know if he said yes to Satō confession because all guys think about is just dirty things, which Kiyotaka denies. Karuizawa expresses her worry about what would happen if Kiyotaka had accepted Satō's confession as the chances of her working for him and her past could be exposed. She insists on hearing what Kiyotaka's answer was despite him resisting several times, before relenting and telling her that they exchanged phone numbers and Satō wanted to start by being friends. Karuizawa thinks that Satō will try and progress the relationship, and asks if he indeeds to reject her. He says he doesn't know yet. Before they end the conversation, Kiyotaka wants to tell Karuizawa something but decides against it because it would be an uneccessary burden on her and it will happen regardless of his warning, instead he tells her to delete the record of their contact, to which she replies that she already has.

As the mid-term results for the Autumn semester are released everyone is surprised at the improvement Sudō has made since the sports festival. He manages to place above the bottom 10 in mid-term results with an average score of 57 and is 12 from the bottom in the class of 40. On the other hand, Kiyotaka once again scores near the average getting an average of 64 points. Horikita once again questions him about going all out in the exams, but he simply replies by saying that was the best he could do. Chabashira sensei further compliments the class on having on expulsion since the start of the school year, a feat not achieved by any Class D in the 3 years she has been in the school. Despite having just completed the midterms, Chabashira sensei informs them of an upcoming quiz that will have an effect on the final exams for the term which will also be a special exam, the Paper Shuffle. The upcoming quiz will determine the which students are paired up for the final exams which will be set by one of the other 3 classes. Once the explanations are complete. Horikita calls together the 2 leaders of the class, Hirata and Karuizawa along with Kiyotaka for a strategy meeting. Wanting to do it in a more comfortable place, Karuizawa wants to have the meeting at Pallet Cafe instead decided that it easier than arguing Horikita agrees. As they are discussing, Kushida comes up to them and asks to join them for their meeting. Horikita agrees and tells Karuizawa, Hirata and Kushida to ahead first. Sudō shows up and says that he can't join immediately due to club activities, and is told to join them later at Pallet. Having completed his job of connecting Hirata and Karuizawa to Horikita and thinking about fading into the background and creating some distance between himself and Horikita, Kiyotaka says he is going home. Horikita stops him by enticing him with information about Kushida, Kiyotaka expresses interest about finding out the reason for Horikita and Kushida not getting along and decides to stay in exchange for that information. Horikita tells him that while she initially thought that the first time she met Kushida was on the bus to school just like Kiyotaka but in actuality they are from the same middle school. She follows up by telling him about a rumour that she heard back in school about a single girl destroying a class till the point no one attended school until graduation. Why she did it or how, Horikita doesn't know though. They wonder if Kushida can really destroy an entire class by herself or even worse an entire level. They discuss what methods she could have used, Horikita proposes violence, or perhaps political power. Kiyotaka says, lies could also be used. They wonder if Kushida right now can destroy Class D with her lies and violence but he says, there would be opponents to tough for her like Kouenji and Sudō, but it would not be impossible to destroy the class with lies. They determine that Kushida is willing to destroy their class in order to protect her past and her presences is not good for the class, hence they discuss if they should expel her, but with Horikita's new perspective from losing at the sports festival she doesn't want to resort to that. Finally Horikita reveals that she knows that it was him who had sent the recording to Ryūen at the end of the sports festival and thanks him even though if he had known the outcome before hand.

At Pallet Cafe Karuizawa complains about Kiyotaka and Horikita's lateness but receives no apology. They quickly begin discussing their strategy for the upcoming paper shuffle exam. Horikita explains the proof of there being a rule to determine how the pairs are formed in the quiz, she believes that the pairs formed will the top students paired up with the bottom students and asked Hirata and Kushida to use their network of upperclassmen to confirm her theory on how the pairs are determined. Karuizawa quickly points out if that is the case, the students in the middle of the class are those who are in the toughest position. Aside from determining what to do for the pre-quiz, they discuss which class they should 'attack' for the paper shuffle exam. Hirata produces a memo which he belives what who each class will choose to attack. Class A will should Class D, while B should choose, C should chose B and D should choose C. He believes this is the case because A has the highest academic ability and can set questions that will be hard for D to solve leading to an easy win. D will should choose C because they are the closest in academic ability based on their monthly class points. Kiyotaka points out that class points may not be an indicator of their academic ability and that do not have a good grasp on the other class academic ability only their own. Hirata also bases his guess on the classes wanting to close the gap between each other. Most importantly, they agree that to close the gap in points, D should target class C. As the meeting ends due to Sudō and Hirata having club activities, Horikita once again asks if Kiyotaka is going to not do his best in the tests again, he replies that he will think about it.

A day before the quiz to determine the pairs, during homeroom Hirata and Horikita both present their strategy for the quiz to the class. Horikita begins with an apology to the class for her failure and attitude during the sports festival and says she wants to work with everyone from now on. Her idea is to ensure the pairs are balances by having the top 10 students score 85 and above while the bottom 10 students in the midterm average score 0. The next best 10 students should aim for a maximum of 80 points while the next bottom 10 students should get 1 point. This way the pairs will be balanced. While what Koenji will do is left ambigious, the class decides to go with her plan with Hirata's support. The following day before the quiz, the class each class is setting for is decided. Class D and C will set for each other while Class B and A will set for each other. From the groupings, Kiyotaka infers that Sakayanagi made the choice as she wants to widen the gap between the class rather than aim for Class D where they have the highest chances of winning which would have been Katsuragi's choice. When Chabashira sensei tells everyone to take the test seriously, the weaker students who are supposed to get 0 points are worried, but Horikita confidently says that her plan is correct leading the others to feel relieved. Seeing this Kiyotaka thinks class D has changed for the better. The pairs are announced soon after and Kiyotaka is paired with none other than Satō who appears happy that she is paired with him. As it happens, Koenji goes along with the plan and ends up paired with one of the weaker students. Kiyotaka thinks that since Satō is one of the weaker students, he will have to get more points for this exam. With the pairs dertermined, the next stage of their strategy involves setting up study sessions for the entire class which will be lead by Horikita, Hirata and Kushida. Horikita will be incharge of session 1 while Hirata will be incharge of sesseion 2 for those with club activities while Kushida will help with both. While most of the plans are settled, 2 class D students Akito Miyake and Haruka Hasebe approach Horikita for advice as they were paired together and both had average scores in class, furthermore from their test results they have the same weak points, which for the coming exam since they couldn't cover each other's strong points. Horikita suggests joining one of the study sessions but because Hasebe is on bad terms with some of the girls she declines and leaves. Miyake is then asked to join alone but he declines as well as studying with a group of girls would be uncomfortable for him hence he leaves as well. Horikita discusses with Hirata, Kushida and Kiyotaka what to do about them, and decides to teach them herself but Hirata refuses as she would be taking on too many responsibilities as she also has to set the questions. Fortunately Yukimura for overhears them says he will teach them but the leaders will have to convince them for him. Horikita stares at Kiyotaka and forces him to look after the group, and report back to her. He relunctantly agrees as she starts to threaten him.

After class that day, the group consisting of Miyake, Hasebe, Yukimura and Kiyotaka head to Pallet Cafe to discuss their study plans. Yukimura looks over their previous test and Hasebe asks him why he is willing to teach them. He replies that being good academically is not good enough at this school so he wants to do want he can for his class since he is weak at other areas and teaching smaller groups of people is easier. While they are at the cafe, Kiyotaka notices several people looking towards his direction. Daichi Ishizaki from Class C is at the cafe and buys a cake. Upon seeing the cake, Kiyotaka remembers that his birthday is tomorrow and thinks that it's a day he doesn't really think much off, but ponders about how you would normally spend the day with your friends or lover. He wonders if next year someone will remember his birthday. While Yukimura is looking over the pairs notes. Kiyotaka stands up and goes to find Sakura who he noticed was following him this whole time. He gives her advice about joining their study group, while thinking that for Sakura interacting with people like Miyake, Hasebe and Yukimura is not difficult for her as they were all very similar when interact with other people. He also says that it will be okay because he is around and reassures her but tells her she must ask them herself. By the end of the day, Hasebe and Miyake accepts Yukimura proposal to teach them and also expresses interest in setting questions for he exam which Kiyotaka promises to tell Horikita. He also learns from Miyake that Class C's Kaneda is likely to be setting the questions for class c. Sakura is unable to gather the courage to ask to join the study group as the day ends. That same night, Kiyotaka calls Horikita to report on the group. They discuss about the other study sessions, and Horikita mentions that it is difficult to teach large groups and people like Ike and Yamauchi have low attention spans. She asks for Kiyotaka's help in managing them during his off days from his study group. Furthermore, they talk about Kushida betraying them and the possibility of their questions leaking. Horikita decides if too many people sets questions the chances of leaking is higher so she intends to do them herself. As he ends to conversation with Horikita, he receives mail from Ryūen, asking for he is. Kiyotaka realises that if he knows his unassigned number, Ryūen has already found his spy in Class C Manabe. Not caring at all, he doesn't reply and goes to sleep.

The following day, Kiyotaka participates in Horikita's study session. Where Satō is present, she attempts to get close to Kiyotaka setting next to him asking him to help her study, Horikita even encourages him to teach her himself but he says his scores aren't much better than hers so Horikita has no choice but to teach them herself. Also there at the library where they are studying is Ichinose who is having her own study session with Class B students. After the study sesssion is over, Horikita asks Ichinose if they can talk alone while Kiyotaka is given permission to stay and listen to them talk. They talk about Ichinose's class and what she would do if they are in trouble. Ichinose says she will help them if they are in trouble beacuse they are her important friends. She even includes both Horikita and Kiyotaka as her important friends and would be willing to help them if they ever need it, even if it means lending them large sums of points. Horikita asks her how good of a person she can be, but that is just who Ichinose is. When she leaves, Horikita and Kiyotaka discuss what they plan to do about Kushida, Kiyotaka mentions he has a plan to use that involves someone like Ichinose who is a good person and is trusted by everyone to allow for a fair 1v1 between Kushida and Horikita but she declines this saying she won't use Ichinose.

After leaving the library, they meet Kushida who Horikita wants to talk to. Kushida doesn't want Kiyotaka there so he excuses himself but Horikita calls him on his phone so he can listen to their conversation. They talk about being from the same middle school, and Horikita tells her she won't reveal her secret but that doesn't satisfy Kushida therefore Horikita proposes a duel. Where Horikita will resign from the school if she loses and if Kushida loses she will have to help the class. They agree to challenge each other in a single text paper and see who can individually scores the higher instead of total scores, Kushida is allowed to pick the subject as well. In order to ensure the deal is followed through, Horikita calls her brother Manabu who is the witness to the deal. With Manabu as witness, Kushida can be sure that Horikita will not back out from resigning. Kushida agrees but says she has a one extra conditions and tells Horikita that she knows that Kiyotaka is listening through the phone and asks him to come out. Kiyotaka meets up with them and Kushida request that if Horikita loses, Kiyotaka must also resign. Horikita says he isn't involved but Kiyotaka bets on Horikita in exchange for hearing the truth about Kushida past. Kushida agrees as if he gets expel it would be unsatifying for Kiyotaka if he doesn't know why. Kushida explains wanted to be the most liked person so she created her facade which she uses today but in order to release the stress of always been nice, that she used to post her thoughts on a blog which was found out by her classmates in middle school which turned everyone against her. In order to destroy everyone she used the secrets she learnt from every one of her classmates that she didn't post on the blog an spread them to her class. This caused the class to fight each other, they were destroyed by the truths that Kushida had learnt by being friends with everyone. Kushida decides to challenge Horikita in the maths paper and Kushida warns them they she can get Ryūen to cooperate and get the answers from him but Horikita is betting on the fact that he won't do that.

On the 5th time Yukimura's study group is having a study session at Keyaki Mall, Ryūen and his lackies appear to disrupt their study session, Ryūen knocks over Hasebe's drink which angers her. Miyake is the first to react, telling Ryūen to back off. Ishizaki who is annoyed at his attitude is ready to start a fight but is stopped by Ryūen. Ryūen asks no one in particular if they had received his message, trying to find the person who is X who has been pulling the strings behind Class D no one reacts and Miyake is wondering what he is talking about. He lists all the possible suspects like Yukimura, Kiyotaka, Hirata and Koenji before leaving saying that he was just giving an introduction before they would meet again. Once he leaves, a girl from Class C revealed to be Hiyori Shiina who was tagging along with Ryūen returns with 2 drinks in hand offering one to Hasebe saying what happened earlier was his fault and this was an apology for his attitude. Hasebe is surprised as the amount of sugar in the drink is exactly the same as what Hasebe was drinking earlier, she has that she reverse calculated the amount of sugar from the one thrown out earlier. She then asks the group about whether they know anything about the person pulling the strings behind class D but everyone says that it has been Horikita all this time strategising for the class. While she questions Kiyotaka since he is close to Horikita, he replies that it hasn't been the case recently and she is spending more time with others. The others help to sell the story that there isn't anyone working behind Horikita by saying that it's hard to imagine someone smarter than Horikita.

As they end the study session and head back to the dormitories, Kiyotaka asks Hasebe if she knows anything abou Satō. She says she isn't very close with her and suggest askinging Karuizawa, but Kiyotaka thinks that asking her would be tough. So Hasebe proposes asking Kushida who is close with everyone. Hasebe teases Kiyotaka about whether he links Satō but he says that he just wants to know more about his partner for the paper shuffle exam. This prompts Kiyotaka to think that Kushida is an important piece to Class D. On the way back after the conversation the group decide to head to the convenience store together. After buying their stuff from the convenience store, Yukimura asks Hasebe about his nickname Yukimu and is embarrassed by it. Hasebe explains that she gives nicknames to those she is close to. They end up talking about how they are all close with each other because they all find it hard to make friends, they decide this study group should be a new group for people who are loners. They decide to call themselves the Ayanokōji Group because he is the connector to everyone although he weakly protests. From they with them deciding to be a group they decide to call each other by their given names. Yukimura protests as he doesn't like his given name because it was a name given by his mother who he doesn't have a good relationship with, instead he tells them to call him Keisei. Sakura who is following them loudly asks them to let her join the Ayanokōji group. She starts off by saying she is worried about her test scores. Which Keisei rebuffs her by saying she should join Horikita's sessions as more people will be harder to manage and they are at different places in their studies. Sakura then instead says that she wants to join because it's Kiyotaka's group. Akito agrees who feels that Sakura is like them as she has difficulty making friends in class. Keisei also agrees as Sakura is easy to accept but says that no more people should be added or he will leave. Sakura thanks the 2 guys but calls them by their last name. Last is Haruka, who says she can't accept, because the group is supposed to be close so if she wants to join she needs to call everyone by their given names so she needs to call everyone by their given name and everyone has to call her by her given name. Which Haruka asks what it is, Sakura tells her Airi. Airi finds it dificult but she manages to say Keisei-kun, Akito-kun and Haruka-san. She has difficulty saying Kiyotaka's name and as all the eyes are on her but she manages to do it and is accepted into the group.

With the Ayanokōji Group completed, they decide to go watch a movie to refresh themselves from all the studying. With plans to watch a movie made, Horikita asks to meet with Keisei, Hirata, Karuizawa and Kiyotaka the day after coincidently the same day as the movie. Following his conversation with Horikita, Kiyotaka receives a message from Karuizawa telling him about what she found out about Hiyori. She tells him that she had asked around about how much sugar Haruka had put in her drink just like he thought. Kiyotaka passes along the message about the final meeting for class D the day after at 8pm, Karuizawa mentions how late that is and he replies saying that his study group is going to watch a movie. He then tells her about something she wants her to do at the meeting tomorrow. She mentions that it's something very troublesome. Just as he thought their converstion had ended, he receives a emoji of a cake with candles on it from Karuizawa, and some words saying she realised a little late. Kiyotaka thinks about how this is the first birthday congragulation he has received and expresses some regret before deleting the message. He ponders how she found out his birthday, and checks Karuizawa personal information linked to her account and decides to remember her birthday 8th of March. The next day at the movie theatre, Satō and Karuizawa along with people from their study group also show up to the same meeting. Satō acts flirty with Kiyotaka which Airi questions him about but he quickly denies it saying that they are just paired up for the upcoming exam. After the movie, the leaders of the different study groups meet in a karaoke room to have their final meeting. They discuss the progress of all the different groups and whether they are ready for the exam. As the discussion goes on as per Kiyotaka's instructions, Karuizawa acts displeased with Kushida's attitude and throws a drink at her. Everyone is displeased with Karuizawa's actions but she continues putting on the act, until finally apologising and offering to take Kushida's school blazer for drive cleaner as an apology. Once the meeting is over, when Kiyotaka returns to the dorm there is a large number of people there, he meets Katsuragi who is also outside. The large number of people have gathered due to a message placed in everyone's letter box with the message that Honami Ichinose has a large amount of points obtained illegally signed off by Kakeru Ryūen. Ichinose herself appears and declares that the school will determine if it's illegal or not. Kiyotaka notes that the amount of points she saw Ichinose had was more than 10000000 points. As she said, the school declared that it was not illegal the next day.

On the final day to hand up the test papers for the paper shuffle exam, Kiyotaka and Horikita both go to submit the questions. Ryūen is there to greet them happily, when they try to submit the papers, Kiyotaka thinks Chabashira sensei's manner of speaking is strange and as there are about to leave after handing the test to Chabashira sensei. Horikita realises that someone had come before her can submitted test papers and told her that if someone tries to change the test they should not be accepted to prevent leakage by a spy working against class D. Horikita and Kiyotaka try and think of counter measures as Ryūen leaves above hearing his desired result. Horikita reveals she expected this and thanks Chabashira sensei for helping out. Kiyotaka learns that Horikita had told Chabashira sensei before hand that only test answers handed up by Horikita should be accepted and no other students submitted test should be allowed. Horikita apologises for keeping Kiyotaka in the dark. And thinks that now that the threat of Ryūen was taken care of now she can focus on beating Kushida.

On the day of the test, Kiyotaka unexpectedly meets up with Satō on his way to school. The talk about if they are both ready for the exam before, Karuizawa shows up and asks if Satō would like to go get a drink before heading to class. Kiyotaka thinks that they are good friends, as Hirata shows up and says that Karuizawa is unexpectedly the jealous type. Kiyotaka expresses surprise, but Hirata who has been acting as Karuizawa's boyfriend says he can tell that lately Karuizawa has been paying more attention to Kiyotaka. Kiyotaka thinks that that's unavoidable as Karuizawa as a parasite has transferred from Hirata to himself. They head to the classroom together as they discuss about the upcoming exam. Hirata also asks him whether him whether he is the person acting behind Horikita as Hiyori Shiina had been asking around for that person, surprisingly he doesn't deny it. He warns Kiyotaka that class C is looking for him and he should be careful. As the tests begin, Kiyotaka watchs Kushida for her reaction, he notices her panic as the tests go on. After the tests are over, Horikita says that she thinks got around 98 for the test once it is over. As every leaves, Horikita asks to talk to Kushida and Kiyotaka follows along, Horikita tells Kushida that she thinks she got 98 for the maths test, Kushida replies that she doesn't think she can reach 80 on her test therefore, Horikita wins the bet. Horikita asks Kushida to stop interfering with the class, and Kushida promises to but reaffirms that she hates Horikita and doesn't shake her hand as she leaves.

Once Horikita leaves, Kiyotaka begins thinking about the current developments, he thinks that Ryūen is not someone so easily dealt with using methods like this. He also thinks about the chances of using a spy in each other classes and thinks that the chances of that depends on the exam themselves. Kiyotaka also thinks that this battle was a complete win for class D. As he is thinking he receives a meesage from Ryūen, asking what is he planning. More message comes but he ignores them finally a Ryūen sends an image to Kiyotaka. Kiyotaka knew it before hand but the image he receives proves that Manabe had revealed everything to Ryūen. Finally Kiyotaka says he is waiting for Ryūen to come at him in his own arena, already aware of what he intends to do.

At the end of the volume, Kushida meets with Ryūen and demands to know why the questions she was expecting did not show up on the exam. Ryūen reveals that someone had places cheat sheets in her blazar to frame her for cheating if she got full marks for the exams. Hence changing the questions saved Kushida from being expelled. Kushida wonders how they managed to get it inside her blazar and Ryūen asked if anything weird happened. She explains what happened in the Karaoke room with Karuizawa which Ryūen already guessed. He also reveals the existence of someone working behind the scenes of class D, and shows Kushida the email he received from X. In exchange for information, X requests for the questions and answers to the test that Class C prepared for class D or if they were already given to Kushida, he requests that the questions be changed. X had read Ryūen's choice to change the test questions as he didn't want to expell Horikita, or get Kushida caught for cheating because that was boring. In exchange he received information about Horikita's plan to prevent Kushida and Ryūen from changing the questions. He also says that he didn't send the letter regarding Ichinose, that was also X's handiwork. Finally he shows Kushida a picture of Karuizawa and says she is important to finding out who X was.

Volume 7
It is already the middle of December, Kiyotaka is meeting with Airi Haruka and Keisei and Keyaki Mall. The Ayanokōji group have been getting closer, meeting 2 to 3 times a week. However, due to Akito's club activities the group meets every friday and wait for him to arrive. When he arrives, they are talking about hobbies, Kiyotaka thinks that it's good to see that Airi has become more talkative and is able to join the conversation. When the topic of hobbies turns to posting pictures on SNS,both Kesei and Haruka end up talking bad about people who post pictures on SNS, as Kiyotaka tries to cheer Airi up, they realise the effect their words have on Airi who used to secretly posts pictures on SNS they quickly apologize. The conversation then turns to the topic of Class D and Ryūen, as Akito tells the group the guys from class C who where interfering with Akito's club activities, Kiyotaka notes that Komiya is watching them from away. They begin discussing the odd behaviour of Class C and Kiyotaka thinks that since they aren't making any moves, Ryūen has already narrowed down his choices for who is X. Furthermore, since he already knows about Kei Karuizawa, it's only a matter of time before he makes his move. Kiyotaka already knows what Ryūen intends to do just not when he intends to make it. The conversation progresses and the group think that Class D's improvements over the last few exams have caused Class C to be nervous, hence their current actions. As they talk about all of the previous exams and the outcomes and strategies, Kiyotaka thinks that's most people in the class don't really know what happens behind the signs of their special exams. The group then express interest in knowing what Horikita was thinking and what she thought Ryūen strategies were for the previous exams. With all their focus on him, he tells what he knows from what Horikita "told" him. He tells them about what Ryūen did in the previous exams but leaves out the fact that Kushida has been betraying them. As they talk about how amazing Horikita is, the conversation shifts to whether Kiyotaka and Horikita are dating or if he likes her. He denies both accusations, and they talk about christmas which is coming up which is an important day for couples. All the guys end up saying they are spending the day alone, as the groups talks about all mannner of topics, Airi expresses her happiness at being about to talk to everyone like this. As they leave to get dinner, Kiyotaka excuses himself to go to the toilet, this makes Komiya who is following them decide to follow the group instead. Kiyotaka uses to chance to confront another person stalking him, Masumi Kamuro from Class A, he asks her what Sakayanagi knows about her to force Kamuro to follow her orders. Kamuro at first denies this but when Kiyotaka threatens to tell Sakayanagi about what a poor job she did watching Kiyotaka, Kamuro says are you planning on threatening me too. Revealing that Sakayanagi does now something about her. Kamuro threatens Kiyotaka back and says she can reveal his existence to Ryūen who is looking for him, and they strike a deal to not get in each others way, letting Kamuro continue her job and Kiyotaka existence is not revealed by her.

In school, Sudou speaks to Horikita about being pestered by Class C students on his way to school. She asks if he got into a fight which he denies saying he won't break his promise to her. Kiyotaka also informs her about the Class C students pestering Akito, Horikita surmises that Ryūen must be looking for him and it's only a matter of time. She wonders if Ryūen has already found him, but he tells her if that's the case all the focus would have been on him and not on the others in the class. She then asks if he has a plan to stop him, expressing some concern, Kiyotaka continues his act and tells her he has no plan. She also wonders why he is still spending time with the Ayanokōji group since exams are over and there isn't much point, he tells her it's more enjoyable than spending time with her while thinking Horikita doesn't yet understand what being friendly is yet. She once again confirms if he is really helping her, and he replies that he will doing as much as he can. During lunch, Horikita asks Kiyotaka for a favor. She asks if he can return a book to the library for her, as the book is popular and there is a shortage of it in stores, Kiyotaka who has been wanting to read the book has not been able to. She proposes that he return it for her so he can borrow it from the library immediately so he can read it. He wonders if this is a how Horikita shows her kindness as he accepts the request.

He immediately heads to the school library to settle the matter as the book needs to be returned that day, at the library he chances upon Hiyori Shiina, trying to reach for a book that is too high for her, he helps her and they begin talking. After talking about different types of books, She asks if he wants to eat lunch with her, as she wants to talk more about book since class C does not have anyone who likes books. Kiyotaka at first thinks this could be a trap by Ryūen but sensing his hesitation she says she isn't interested in the battle between the classes. In the end, in decides to have lunch with her after borrowing another book recommended by Shiina. At lunch, Shiina brings out a stack of book from her bag and asks if Kiyotaka would like to borrow one. She tells him she always brings around books with her so she can lend them to people she finds who also likes book. Kiyotaka borrows a book he hasn't read, while he thinks it could be a trap and he should be on guard he also thinks meeting her at the library was purely a coincidence and Shiina could just be a book lover.

After school, Kiyotaka gathers with the Ayanokōji group, and he is surprised to see Akito there who tells him he skipped club pratice because of the class C guys perstering him. Haruka suggests to tell the teachers, but Akito replies they can't do anything because students are free to learn about club activities. They realise that Komiya has been following them around recently and dicuss the rumours of the mysterious strategies working behind Horikita, the talk about the possibilities, such as Koenji who they say is unlikely because of his attitude and Hirata would could be the strategist. Akito doubts there is one, when Airi asks if Kiyotaka is the person because he gives advice to Horikita and is reliable and smart. He says that it's the other way around and he always receive help from Horikita instead. The rest suspect because he is close to Horikita he is being targeted too. He also mentions because everyone is being followed he has not been able to make any moves or talk to Hirata as well. He thinks there is no need to create more baits for Ryūen to use by carelessly making contact with Hirata and finally concludes that Ryūen is probably just waiting for the perfect time to strike.

The next day after class, Satō comes up to Kiyotaka and asks him if he wants to get a drink with her, unfortunately for her due to Chabashira sensei sending signals that she needs to speak with Kiyotaka, he turns Satō down. Chabashira asks him to follow when he leaves the classroom leading him to a reception office where the principle and another man is waiting for him. As he enters the room, Chabashira sensei and the principle both leave Kiyotaka alone with this man. They begin to talk, he tells Kiyotaka that the papers for him to leave school is ready all he has to do is sign it. Kiyotaka says no. The man proceeds to tell Kiyotaka about his butler Matsuo who helped him enroll into this school and about Matsuo son who was expelled from school due to the man's influence furthermore he has prevented the son in finding jobs and is forced to work part time to survive. This man is Kiyotaka's father although they may share the same DNA, both of them have never treated each other as father and son. Kiyotaka says that's expected considering he didn't do his job. His father tells Kiyotaka how Matsuo committed suicide by burning himself to death after his pleas falls on deaf ears. Kiyotaka tells him if he is died than all the more reason to stay in the school to carry on Matsuo's wishes. His father mentions he has changed in this past year, and says how upset he was when the white room was closed for that one year which gave Kiyotaka a chance to escape, but now the white room is up and running and wants to take him back. Kiyotaka tells him that, the white room was a great education having learnt many things but his curiosity means that he also believes there are things to learn outside the white room especially the things his father deems worthless. He also suspects his father who has great influence outside the school has less influence in the school because the body guards who usually follow him are no where to be seem implying that to even enter the school his father had to make concessions. Finally his father asks him which would he prefer, to leave the school by his own will or does he have to force him. Kiyotaka replies he doesn't intend to leave the school. They are then interrupted by the schools chairman Sakayanagi, upon hearing the name he thinks about Arisu Sakayanagi and whether they have a connection. Chairman Sakayanagi greats Kiyotaka's father and says it's been 7-8 years since they last met, they talk about how weird it is that Kiyotaka got to enter the school because normal applications to the school are just a farce so he shouldn't have been able to. Chairman Sakayanagi reveals it was him who let Kiyotaka enroll. Kiyotaka father then says that as a parent he should be able to take out his school, but Sakayanagi replies normally that is the case if the parents pay school fees or the student is having trouble in school like bullying but that's not the case so the school will protect the student's interest. Finally Kiyotaka's father leaves and says he won't be coming back again. With the chairman and Kiyotaka alone, Kiyotaka asks him several questions one regarding Arisu Sakayanagi who the chairman replies is his daughter which answers the question about why she knows about the white room and another about whether the school really selects students based on the evaluations and opinions of the middle schools and that applications are all fake. He comfirms this and Kiyotaka now understands why students like Ike and Sudou or students with a hidden past like Karuizawa and Hirata can get in.

Kiyotaka leaves the reception room and Chabashira sensei is waiting for him outside and the talk. Kiyotaka tells her he knows everything after talking to Chairman Sakayanagi, he knows she never talked to his father. More importantly he also knows why he was placed in class D. Chairman Sakayanagi thought that because Chabashira sensei didn't seem to have ambitions to raise her class, Kiyotaka could have a quiet existence. However, due to the many irregular existences in her class this year like Horikita, Hirata and Kushida her desire to reach class A which she had buried deep down came back, hence she threatened him before the survival island exam. He tells her he has no more reason to help her and she can't do anything about it as she is a teacher and she cannot simply break the rules and expel him. They part ways with Kiyotaka thinking about the situation ahead, he thinks about losing his reason to aim for class A and that at this point it doesn't matter if Karuizawa reveals his existence to Ryuuen as even if he does nothing it wouldn't affect the expected outcome. On the way back to the dorm, he overhears a 2nd year talking on the phone, and watches as she falls down. Kiyotaka goes to help her but she quickly gets up and leaves. Once she is gone, he asks Karuizawa via message if they can talk getting her okay, he calls her. He tells her that he has lost the reason to aim for class A and tells her that their relationship will end with this phone call. He apologizes to her for getting her involved in all sorts of things especially with Ryūen. While they are thanking, he sports a charm on the floor where the 2nd year fell. He decides to pass it to the manager of the year 2 dormitory so it can be given back to the 2nd year he saw fall down. Once back in his room, he cleans his room and boils water. As he waits for the water to boil, he reflects on what has happened today, he thinks about his conversation with Chabashira sensei and what he needs to do about Ryūen. As he is thinking,he hears his someone calling his room from the front lobby. Since the call is coming from the front lobby it can't be his classmates. Horikita Manabu is coming to see him. He lets him in and Manabu tells him about the problem with Nagumo and how he has complete control over the second years not just his class. He also tells him about how Nagumo went behind his back to gather information on Ichinose and force her into the student council. Manabu comes to request his help in dealing with Nagumo to protect the school traditions, but Kiyotaka doesn't know if they should be protected. Manabu tells him if he wants he can just his Suzune as his face in the council and work behind the scenes if he wants as Kiyotaka tells him he has no interest in the student council. Kiyotaka doesn't commit to doing anything just yet thus Manabu leaves but gives Kiyotaka his contact information and asks him to contact him if he wants to cooperate. Over the weekend Kiyotaka spends time with the Ayanokōji group then head to karaoke where they enjoy themselves, as they are heading back they spot an unlikely pair, Ichinose and Sakayanagi the class ledaers of Class B and A respectively. Once the pair part ways with the group after exchanging a few words, Haruak expresses that she doesn't believe a perfect person like Ichinose actually exists. They talk about the coming battles between the classes and Kiyotaka wonders what will happen when Class D reaches Class C and Class B becomes their enemy.

One day after school, Ryūen and his gang of people who specialize in violence, Ishizaka, Albert, Komiya and Kondo visit the class D classroom. Chabashira who sees them leaves the classroom as students from other classes are allowed to visit another class so no rule breaking is actually happening. Sudou is asks him what is he doing here and Hirata intervenes to prevent a fight from breaking out and ask him what he wants with class D. Ryūen says he has come to give a proper warning as he looks around the class looking for someone. He barely glances at Hirata, Kiyotaka, Keisei and Akito and his eyes rest on someone Kiyotaka doesn't expect, Kōenji. Kōenji who doesn't care about the situation simply leaves. This prompts Ryūen to signal his guys to follow him out and the class C students leave. Worried about the situation, Akito, Keisei, Kiyotaka and Horikita follow them out. Hirata reading the situation follows them out. Sudou wanting to protect Horikita follows them as well. Kiyotaka tells Hirata to keep the class calm instead of following them as there are enough people, he agrees and returns to the class. they search for Kōenji by thinking about the places he usually goes to after class. While Horikita doesn't want Sudou there he isn't willing to leave Horikita alone, Kiyotaka thinks him coming along is good due to the previous incident involving class C as that would be a detterant for a fight breaking out. On the main street towards the dormitory, the group spot the class C students who have met up with Mio Ibuki and also Kōenji. Ryūen wants to have a word with Kōenji and they move to somewhere less conspicuous. At the point, Horikita interferes with Ryūen but he expected her to arrive along with everyone else in the group. He expresses that he thought Hirata would also be here, to wish Horikita says not everything can go as he expects. Ryūen tells his gang to surround Kōenji and tells him it was his fault he didn't get more points in the cruise ship exam which Kōenji apologizes for. Kōenji who who is unconcerned by the situation, takes out a mirror to check his hair because it's been windy. He hands Ryūen the mirror and asks him to hold it for him, Ryūen takes the mirror and throws it away shattering on the floor. Horikita and Sudou go and pick up the broken shards to glass when more people arrive. Class A students, Kitou, Hashimoto and Kamuro lead by Sakayanagi arrive and seem to want to join in. Ryūen tells them not to intefere so Sakayanagi sits down on the near by bench and watches them. Kōenji says he wants to leave if there is nothing else but Ryūen says he still has questions. Kōenji then tells him that he is looking for the person interfering with Class C's plans behind the scenes in Class D, but says he is targeting the wrong person as he as no interest in Class C or even Class A and doesn't intend to do anything at all for the class battles. He says he just didn't want to waste time at meetings during the cruise ship exam so he finished it early by figuring out the VIP. He also calls Ryūen dragon boy which greatly amuses Sakayanagi who says that's a good name which annoys Ryūen. Sakayanagi now begins to question Ryūen if this X really exists and begins to tell him maybe he is wrong. She reveals the contract between class C and A regarding transferring 20000 private points per person in exchange for the points in the island survival exam she says that contract was made by Katsuragi and has nothing to do with her. Kiyotaka thinks at this point Sakayanagi probably has full control of class A. She calls Ryūen dragon boi which causes Ryūen to attempt to kick Sakayanagi in the face, but Hashimoto intercepts. Horikita says that that's as far as it goes, but Sakayanagi says nothing happened. Finally Ryūen asks Kōenji one final question, who does he think X is. Kōenji says he doesn't care about anyone in here or in the class which Sakayanagi takes offense with and questions Kōenji about whether he means to include her. He calls her Little Girl which she doesn't like. With the line of questioning over, Kōenji leaves with the scene over the class A students also leaves. Ryūen says that today he was able to reduce his lists of suspects, as he leaves and Class D wonders what he is up to. Kiyotaka thinks that Ryūen's preparations are almost complete as the class D students head back to tell Hirata what happened.

On the last day of term, Kiyotaka receives a message telling him that he is going to go after Karuizawa today. Karuizawa herself sends Kiyotaka a message about Ryūen wanting to see her on the rooftop at 2 pm later that day. She tries to send him a signal in the classroom after the day ends, he meets her eyes and she looks relived before leaving with her friends. The Ayanokōji group decide to meet up at Keyaki mall, while Kiyotaka is preparing to leave, Satō approaches him and asks him out one more time since he already has plans he turns her down again, feeling bad about rejected her twice in a row he tells her he has no plans over the term break so he can go out with her during that time. When he leaves the classroom, the Ayanokōji group is waiting for him, they all question him about what was going on with Satō and Keisei is apparently unhappy with the developments. Akito notices that no one is following them today as they head towards the mall. Kiyotaka thinks that since everything was ending today, there was no more need for Ryūen to send his goons to follow them anymore. A little while later close to 2pm, Kiyotaka excuses himself from the Ayanokōji group, while Airi is a little sad that he is living Kiyotaka thinks that she doesn't need him anymore to have a place in the group. He heads back towards the school and calls Chabashira sensei asking her to meet him in the classroom. At the classroom, Kiyotaka asks for help in dealing with Ryūen who is about to bully Karuizawa which might lead her to resign from the school. Chabashira says she cannot interfere with the students directly. To which Kiyotaka treatens to intefere with Class D's attempts to get to class A, she replies is it not your turn to threaten me. Kiyotaka says he was joking saying that he never expected her to help, he just wants to to watch over them and asks if she will follow him. As the wait in the hallway near the roof, Kiyotaka guess that Karuizawa is being bullied repeated by having buckets of cold water thrown over her as he see's Ishizaki carry buckets of water to the roof. Since 30 mins had past since 2pm he was surprised to see Ishizaki still carrying buckets of water up, thinking that this development was not what he was expecting. He thinks that he could go up now but he already had a planned time to go up and going too early or too late would not be beneficial to his plans so he asks Chabashira sensei to speak with him a for a little while. They talk about the schools system of using points and wonders if they have a planned guideline in place for any situation that can occur, Chabashira says she cannot answer because she is a teacher, but Kiyotaka can infer the truth from the way she acts and replies to his questions. He summises that there are guidelines in place for the use of private points, he understands from seeing the amount of points Ryūen and Ichinose have been accumulating. She finally replies as he guesses the truth that the truth is the teachers themselves do not know how far the points can be used for hence she 'can't answer'. Once they finish the conversation, Kiyotaka says it's time to go and finish this game of hide and seek. He checks the time and asks someone to come to his location immediately. Chabashira says she she doesn't intend to intefere calling someone else would be a good idea. He says he is going up, which suprises Chabashira who says if he does then his peaceful life will be over. He thinks that even if he doesn't go his peaceful life is over. Chabashira sensei, then tells him she was wrong for trying to use him after hearing about him from Chairman Sakayanagi, and asks if he is really stepping down from the raising the class up, he says yes but tells her she should watch over the class properly because even without him Horikita can do a good job bringing the class together. Moments later, the person he messages arrives, Manabu Horikita which surprises Chabashira. Manabu tells tells him to not forget the promise he made. Kiyotaka tells him that all his needs to do is stay outside as a witness and memorise the faces of the people that comes out.

As he climbs the stairs, he meets Albert who is guarding the entrance to the rooftop. He first speaks to him in japanese but get's no reply so he tries english next telling him that he is the one they have been looking for. This grabs his attention and Albert uses his phone to send a message to Ryūen, Kiyotaka tells him to let him through and follow him because without him, Ryūen has no chance of winning. When he reaches the roof, he first checks that the camera on the roof has been dealt with, he sees that it's been covered by black spray paint. Karuizawa is surprised to see him, he tells her he is sorry he is late. Ibuki can't seem to believe that he is X so she tries to convince Ryūen that he isn't. Ishizaki also doesn't seem to believe that Kiyotaka is X but Ryūen is convinced. In order to convince Ibuki, he explains to her what he did in the island exam as proof that he was X. As they start to believe it, they talk about what to do. Ryūen asks him why he would show up when the best thing to do would have been to leave Karuizawa as in either situation his identity would have been revealed he wonders what kind of plan he has to come up here where he is surrounded. Kiyotaka returns the with a question asking if this was supposed to be a terrible situation for him. Kiyotaka explains that he is here because Karuizawa asked for his help that's all. Ryūen then threatens him by saying he will reveal his identity to everyone, he also tells him that even if everything that happened here is revealed the one who would receive the most damage would be Karuizawa and him, his identity would be revealed and her past of being bullied would have been revealed. However, in a show of strength, Karuizawa says if Kiyotaka is exposed then she is fine being exposed too. Kiyotaka then asks if they can leave since being exposed is what they all decided, but he reveals that he doesn't expect Ryūen to accept that conclusion as that's not the type of person he is.

Ryūen grabs Karuizawa by the hear and says that now that Kiyotaka is here her job is over and he throws her aside losing interest in her. Ryūen tells Albert to close the door, and asks Kiyotaka does he know what is about to happen. He tells Ishizaki to attack Kiyotaka, but Kiyotaka easily catches his punch and crushes his fist, causing Ishizaki to crumble to the floor. Albert seeing the situation intervenes but his attack is once again caught by Kiyotaka. Kiyotaka hits him in the stomach to little effect by takes him out by going for his throat. Ishizaki attacks again but is easily dispatched again. Ibuki who has learnt martial arts tries to kick Kiyotaka, he expresses that it's not suprising she beat Horikita, but even she is taken out easily after he dodges all of he kicks with ease. Ryūen says he underestimated Kiyotaka and begins to attack Kiyotaka who dodges most of his attacks but when Ryūen starts talking about how he hasn't felt fear before, Kiyotaka takes a few hits to remember the feeling of pain. Ryūen wonders if Kiyotaka has even felt fear believing that he hasn't, but Kiyotaka thinks that he used to feel fear when he saw people break around him, but he learnt that as long as he didn't lose he wouldn't feel that feeling. Kiyotaka reveals that everything happened as Kiyotaka planned and that even the fight they were having was exactly as Kiyotaka wanted and that Ryūen this whole time was simply dancing the palm of his hand even since he used Manabe as a spy he knew it would come to this. As he plays around with Ryūen, Ryūen asks why someone as power as Kiyotaka is happy to be treated as a normal person if he has any ambitions. Finally bored with the fight, Kiyotaka thinks he made a miscalculation, Ryūen wouldn't be able to feel their difference in power because he did not know what fear is, so Kiyotaka quickly overpowers him and gets on top of him when he knock Ryūen down, repeatly punching him. While Ryūen resists and laughs at the situation, Kiyotaka continues to hit him until he sees the fear in Ryūen. Once he is done teaching Ryūen what fear is, he thinks he shouldn't waste too much time as he can't bear to leave Karuizawa alone anymore.

Kiyotaka goes to check on Karuizawa, who is shivering in the from being drenched and being exposed to the winter winds, he asks if she is hurt but she tells him she is just cold. He asks if he is now disillusioned by him, she says of course because he tricked her in the first place by setting up the trap that let Manabe attack her. He asks why she didn't give him up even then, and she replies that she did it for herself. She falls into him as her exhaustion catches up to her and tells him how scared she was. Once again he promises that he will save her the next time she is trouble. He starts to think about Karuizawa and how he know knows that she won't betray him, revealing that if she did betray him he would have used her guilt to control her further. He thinks that letting her go would be a waste and that Karuizawa's usefulness was know not his priority but ensuring that she remained his was more important. He tells her that Chabashira sensei and Manabu were waiting for her downstairs and she should go home first while he finishes things up here. When she leaves, Kiyotaka wakes up the everyone leaving Ryūen for last. While Ryūen still has some of his strong attitude he loses it once Kiyotaka asks if he wants to be hit again? Kiyotaka tells him his mistake was going after him first, he should have gone after Ichinose than Sakayanagi gaining experience to take him on. He tells him he is willing to take him on anytime but he would prefer not to as he just wants to fade into the background. He also informs him that Manabu is waiting downstairs as a witness to what happen here and Kiyotaka already has an alibi and evidence that he was at Keyaki Mall when the cameras on the roof went down. With Manabe there even if Ryūen revealed everything to the school he would receive the most damage, getting everyone up here in trouble as well. Therefore, Kiyotaka proposes that they just everything that happened up on the roof a secret, but Ryūen doesn't believe him so he says he take all the blame on himself says before he gets expeleld he wants to transfer all his points to Ibuki and pases her his phone. He tells the the remaining class C guys to handle things from now on, saying he will leave the school on his own accord. As he tries to leave Kiyotaka stops him, telling him that he won't grow if he gives up here, Ryūen asks why he is stopping him, he tells him that the contract he has for Katsuragi will hurt class A while he can also help class D deal with class B and A for him. Most importantly if Ryūen suddenly disappears Ichinose and Sakayanagi will proably start to focus on X. Kiyotaka tells him, that he doesn't intend to tell anyone about what happend here and neither does Manabu. Ryūen says he won't be that naive and leaves. The next day Ryūen meet Ibuki who asks him if he really intends to quit after one loss she tries to dissuade him but fails, he goes to see Sakagami the class C homeroom teacher and he says that he was the one who damaged the camera on the rooftop, which Sakagami says is contradictory as someone from class D already claimed responsibility for the damage. Ryūen thinks it was Kiyotaka who did it. Ryūen then asks to resign from the school, Sakagami says if he resigns, Albert and Ishizaki will both resign from the school as well. Ryūen wonders if it was Kiyotaka who gave them the idea to stop him from resigning. He gives up trying to resign as it would be meaningless if Ishizaki and Albert also resigned. Rumors around the school spread that Ryūen has stopped being leader of his class, and is now leaving a quiet life like Kiyotaka did at the start of school, Kiyotaka wonders what Ryūen will learn from this, he doesn't know but he confirms that Ryūen is similar to him.

Volume 7.5
On the 25th of December, Kiyotaka is getting ready to go out. He thinks that on Christmas most people are most likely spending it it with their families or loved ones. He guesses that at this school there will probably be many students spending today with their loved ones too. He opens the window of his room and hears the sounds of some girls talking and laughing and thinks that they seem to be heading to Keyaki Mall as well. Kiyotaka checks the time and sees that it is already past 11 and he should go now since today is the day for his date with Maya Satō, he wonders if anything will change today for him today. He laments that this day must be significant to him if it wasn't we wouldn't have considered going on the date. He continues to wonder if he will experience what is it to like someone, to have someone who is important to him, someone who will become irreplaceable to him. He wonders if something like that is possible for him. As he leaves he thinks back to what happened 2 days ago on the 23rd of December.

On the 23rd of December, he goes to Keyaki Mall early to buy something for a girl, he makes sure to get the best product and buys two kinds of it using reviews from the internet and asking the stores staff. He then heads back to the dormitory where he meets Sakayanagi who is waiting for Kamuro to go out together. Sakayanagi asks if he is feeling ill when she sees the item he had bought earlier at Keyaki Mall, he tells her he isn't. They start talking about what happened with Ryūen just a day before. Kiyotaka thinks it's not weird that the rumors have already spread this fast even though the only people who should have known is the students involved on the roof top. Sakayanagi tells him that the rumors are that Ryūen got into a fight with the people in his class, but she thinks that's a bit wrong, and that she thinks it was Kiyotaka who fought him. However he replies that as she can see he is perfectly fine and hasn't gotten into any fight. She starts by asking if she want's to battle with her, he says he would rather avoid that then she says she has other methods to make him fight her. She then starts to tell him about her plan to destroy Ichinose because she feels bored that class C and D where having such an interesting battle. Kiyotaka thinking that if Sakayanagi focuses on Ichinose he won't have to fight her, riles her up by getting telling her he knows that her father is the chairman and perhaps she isn't that smart and got into the school because of him. Sakayanagi turns this back on him asking him if he isn't being just arrogant because he is a success story of the white room and that because of the white room he both has incredible knowledge and physical skills. She tells if it's her job as a real genius who doesn't need the white room whose job is the create geniuses to defeat Kiyotaka. Kamuro then arrives, telling Sakayanagi not to wander from their meeting place. They start talking about what kind of person Ichinose is, before Kamuro and Kiyotaka both agree she is a nice person who is hard to attack because she doesn't really have weak points, but Sakayanagi replies every has weak points and reveals Ichinose has a secret that is the same as Kamuro's. She says that she got the information via cold reading Ichinose, but Kiyotaka thinks she probably used both hot reading then approached her to confirm with cold reading. As Sakayanagi leaves she observes that from Kamuro attitude that she has already met Kiyotaka but doesn't do anything because she says she is in a good mood. Kiyotaka thinks that from this conversation, Sakayanagi is not likely to spread the knowledge about his past as she wants to beat him herself. He also says he originally wanted to give the things he bought to the girl but saw that she was feeling well enough to go out since he saw her earlier when he was leaving the mall. With no more plans for the day, he decides to go watch a movie.

Kiyotaka goes to the movie theatre along to watch some B-movie. He narrates that since coming to school he gained interest in watching movies. He picks a set near the centre of the theatre and is surprised to see so many sets of 2 taken, as the movie isn't some romance or Christmas movie. When he goes to his set he mentions how he enjoys going early to see the previews of upcoming movies. When he reaches his seat, there is a couple to his right but the seat on his left is empty. When the lights have dimmed he notices someone else coming along to watch the movie, that person is Mio Ibuki who he previous knock unconscious on the roof the previous day. She sets down next to him but doesn't notice Kiyotaka. Unfortunately, for him Ibuki doesn't realize that he is already using the armrest on the left, and he attempts to use it too and their arms touch causing her to notice him. Ibuki is annoyed at seeing him and is constant watching him as the movie plays. Kiyotaka notices that he is used to being observed in the white room so he ignored her and focuses on the movie. However, at the climax of the movie the screen blacks out and there is an announcement that they are experiencing technical issues from the staff. They finally talk a little about Kiyotaka's past actions and Ibuki is annoyed that he made a fool of her by tricking her. He tells her that's power, and that you should always be aware of the difference in power between your opponents. He tells her unlike the rest he isn't interested in the class battles but she replies that his past actions have been to help his class which contradicts his statement. With atmosphere between them both sour, they turn their attention back to the screen and wait. After 20 mins, they are still waiting, while many other students have already left Ibuki and Kiyotaka have not. Ibuki tells him that she doesn't want to leave before him. While Kiyotaka is interested in the ending of the show but doesn't want to simply check how it ends online. Unfortunately for him, the movie screening is cancelled and they both leave the theatre. As they part ways outside the theatre, Ibuki grabs Kiyotaka and drags him into the corner to hide. She tells him Ishizaki is coming and they hide from him, Kondo and Komiya. They overhear them talk about what happen with Ryūen and Ishizaki says his leadership is over and from now on maybe Kaneda will be making the plans. Once Ishizaki is gone, Ibuki and Kiyotaka start talking when Ibuki says that Ishizaki told her that Ryūen didn't resign from the school, she asks if Kiyotaka has anything to do with that, to which he just denies it. Finally she can't take it anymore and asks Kiyotaka to fight her one more time. Kiyotaka thinks that Mio who is confident in her fighting ability cannot accept defeat and also doesn't understand the difference between males and females in terms of fighting strength although he thinks that she would beat any guy who didn't have the same experience in martial arts as her. He accepts the condition as he doesn't think she will back down and asks if she is free now. He tells her he will only accept the fight now and if they can't find a place that isn't filled with people or cameras they should give up. As they walk around, Ibuki finds a store room filled with drug store goods that is only for staff which the has been left open and enters it. Unfortunately, the door cannot be opened from the inside due as a safety precaution for stealing and they are trapped there. In the end, they decide to have their fight there and Ibuki sets the rules. That the match is only over when one side gives up Kiyotaka agrees only if he can set one condition, if he wins Ibuki can never bother him with any more personal battles any more. Ibuki starts by launching a flurry of kicks, which Kiyo blocks as dodging is hard with all the goods around that he doesn't want damaged. He strikes her in the forehead with an open palm from his less dominant left hand which almost knocks her out, then she continues to attack finally he grabs her by the neck and she is unable to move, he tells her that he should know by watching Ryūen already and she gives up. She asks him why he is so strong and he tells her he trained a lot, Ibuki doesn't really believe his answer. Now they decide to get out of the trapped room, Kiyotaka who remembered the name of the staff who left the door open calls the drug store and asks for him by name. He pretends that Ibuki is his girlfriend and they wanted to fool around in the room. The staff member leaves them after scolding them for going in but doesn't report it as it was his duty to close the room so he was also at fault. Ibuki promises to not battle him anymore as they part ways.

On the way back to the dormitories, Kiyotaka spots Shinohara, Satō and Matsushita and decides to follow them because he thinks he might get some information. He overhears them talking about not having boyfriends as he follows them but when his name comes up when the other girls question Satō, he decides he doesn't want to hear and takes some distance. He walks around the book store and sports Ryūen looking at book on science, he is impressed that after one day he is already walking around but decides not to approach him yet. As he is looking around the book store. He sees Shinohara alone and guesses that the other 2 girls have gone to the toilet. As he observes Shinohara, he sees 2 upperclassmen comes over to her, a couple and the female upperclassman begins to harass Shinohara due to them bumping into each other earlier, and the upperclassman feeling that Shinohara gave her a dirty look after. As the commotion looks to escalate, Kiyotaka is about to go and help but Ike appears and intervenes telling the upperclassman that Shinohara always looks angry and gives mean looks, he also says he saw a teacher around here. This prompts the male upperclassman, who Kiyotaka recognizes as the guy he bought the mid-term tests for back in the first term, to take his girlfriend away. Shinohara thanks Ike but wishes he could have solved it better, Ike leaves but tells Shinohara to enjoy her boyfriendless Christmas which makes her made. When Satō and Matsushita return and determining that he won't receive any useful information, Kiyotaka leaves the book store and goes home. Back at home, he receives a call from Haruka later at night, who tells him that the group will be having a party on christmas day, but Kiyotaka tells her he already has plans. Being Christmas day, Haruka asked him what he plans on doing on christmas day, deciding it better to tell the truth then having to explain it if they run into each other on Christmas day, he tells her he is going to go out with Satō. Haruka thinks that he needs to think of an excuse for Airi for not joining the party that day because if she sees Kiyotaka and Satō she might faint. While she thinks fainting is too much, if it's Airi it might happen and he thinks that he needs to be careful if not she will become depressed. Sensing Kiyotaka's change in atmosphere when Haruka asks about Airi she asks him if he knows about Airi's feelings. Kiyotaka confirms this, which makes Haruka think, he isn't that dense. Kiyotaka thinks that Airi is like a little chick taking her first steps in the world, and that it was always likely she would like him as he was the first guy she ever talked to, he thinks that he she starts to get used to more people and meet other people those feelings of hers might change. He apologizes for not being able to join but Haruka says it's fine as the group was never meant to force them to join all their activities. That same night, he also calls Karuizawa to ask her to pass him information on Satō but he doesn't express any concern for her after what she endured on the roof which angers her.

On Christmas eve, 24th of December Kiyotaka has made plans to meet 2 guys. One of which he asks to meet, and the other one wants to meet him. He meets the first guy at an area near Keyaki Mall where there are benches at about 7 in the morning. It is currently snowing and the forecast says that it will snow for the rest of the day. He sits down on a bench and the person he is meeting Ryūen appears and takes a different bench. They discuss about what Ryūen is going to do from now on, and how Kiyotaka stopped him from resigning from the school. Kiyotaka thinks that Ryūen has a lot of potential and gives him some advice. He tells him that he shouldn't follow the obvious order of which classes to attack and he can attack any class. Ryūen says that even if he beats every other class there isn't any point because Kiyotaka is around. Kiyotaka tells hims insider information about Sakayanagi intended to attack Ichinose during the next term, telling him that it is his chance to attack Class A. Ryūen asks Kiyotaka if this information is accurate he replies about 50-50. They also talk about the problem in class D, Kushida who wants to expel Horikita. Kiyotaka tells Ryūen that class D who will become class C in the new term may drop back to class D because Kiyotaka wants to expel Kushida. They both agree thought that Kushida would be a very useful asset in the coming class battles. Finally, Kiyotaka asks about Ryūen's plan to save enough points to transfer all his classmates to class A. Kiyotaka at first thinks it's unfeasible but upon recalculation he says that the plan has about 5% chance of succeeding and isn't a plan he would come with because of how low the chances are, Ryūen says while they are similar that is where they differ. Ryūen finally asks Kiyotaka why he is letting the snow pile up on his head, but he replies he just wanted to feel what it felt like. Based on their earlier discussion, they both agree to a cease fire between their classes for the coming term. Kiyotaka asks if Ryūen intends to work behind the scenes of class C but he says he intends to leave it up to both Shiina and Kaneda. They shake on their agreement. The second person who Kiyotaka was supposed to meet, Manabu the previous student council president turns up and is surprised to see Ryūen there. Ryūen challenges Manabu to a fight,trying snow in his face and aiming for his stomach, but Manabu easily blocks it, Ryūen says he thought Manabu was just a smart guy, impressed with his fighting ability. Kiyotaka thinks that the reason they asked them to meet at such close timings was so the 2 of them would be able to meet. Manabu then begins to tell them about the promise they made for his help on the rooftop. Manabu wants Kiyotaka to stop Nagumo from going out of control, he tells them that Nagumo has expel around 17 students that were in his way and has gained control of his entire year. On top of that due to his new position as student council president he has the right to set special exams, saying that the island survival exam was previously thought of by a former student council president. While both Ryūen and Kiyotaka both don't think that Nagumo's methods are particularly right or wrong they hear Manabu out. After hearing enough, Ryūen leaves saying he doesn't want to be brought into the situation and leaves. Manabu asks if Kiyotaka wants to make Ryūen his ally but Kiyotaka tells him his goal was mainly to get himself out of Ryūen sights. Kiyotaka says in order to take down Nagumo, he needs data. Manabu says of course, and provides him with all the data he has collected with faces and names on the student council members. He aslo tells him that there is someone in the 2nd years who opposes Nagumo and he wants to tell that person Kiyotaka's name. Kiyotaka says that he definitely doesn't want to join the student council but Kiyotaka doesn't mind if the 2nd year student knows his name, he does that thinking that since there are people who already know his true abilities there is no more merit in trying to hide them completely. Before Manabu leaves Kiyotaka asks him about his sister, Manabu says he can use her however he wants. But what Kiyotaka wants to know is why he is so cold to her responds that he should already know she possesses good abilities, Manabu says he knows but she is only aiming for Manabu and that's the problem. Kiyotaka calls it a problem of 'Final Station', and confirms that Horikita will have Manabu's recommendation if she wants to join the student council.

Having met the 2 people he had planned on meeting, Kiyotaka goes back to his room and passes some time before decided to talk to Horikita about joining the school council, he messages her but she has already gone out she asks him to meet her at the cafe if she wants to talk and he agrees. At the cafe, he is surprised to see Kushida with Horikita and asks who invited whom. Horikita says she invited Kushida and Kiyotaka thinks that she is working hard on making Kushida an ally. Kiyotaka tries to leave because Kushida is there not wanting to talk about the Nagumo issue, but Horikita forces him to talk saying that Kushida is an ally. In the end, he decides to simply ask if Horikita would join the student castle, not wanting to talk about Nagumo in front of Kushida. He tells her that her brother wants her to do it, which Horikita doesn't believe so he simply asks her to call him to confirm. She says she doesn't have his number so Kushida offers to ask Tachibana who was Manabu's secretary as she has met had many times. She receives the number and Horikita calls Manabu while being extremely nervous. Manabu confirms that he wants her to join the student council but he declines to join, Horikita is then annoyed that Kiyotaka is the person connected her to her brother. Having finished half of what he wanted to talk about, Kiyotaka leaves the 2 girls. Later that night, Airi visits Kiyotaka's room around 10pm, having been out with Haruka all day. She wants to hand him a present, because he won't be around at the Ayanokōji Groups party tomorrow. He receives a pair of winter gloves from her since he said he wanted gloves. Kiyotaka is glad that Airi seems to be doing fine with the Ayanokōji group even without him he also thinks that he would have invited her in for a drink if it wasn't so late or Christmas eve as he sees her off.

On the 25th of December, as Kiyotaka prepares for his date, he thinks that today is the day for his first even date and wonders what he will learn from this experience. Kiyotaka meets Satō in the lobby. She teases him about being excited about the date because he arrived at the meeting place first and was early. Kiyotaka plainly tells her he actually just arrived. Since they were both ready, Kiyotaka suggest that they leave for the movie that they had planned on seeing. However, Satō is hesitant to leave, which makes Kiyotaka slightly suspicious. Satō says she can't find her phone and starts rummaging around her bag for it, as she is looking for her phone,Kiyotaka spots a wrapped package in her bag, thinking that it's rude to stare at it too long, he offers to call her phone for her to help her find it. Satō remarks how kind he is to help her, but he tells her anyone in the same position would have done the same. Once again Kiyotaka suggest they should start leaving, but Satō is slightly hesitant. Suddenly the lift opens revealing Karuizawa and Hirata. Spotting Satō and Kiyotaka they mention that seeing the pair of them together is a slightly weird. In response, Kiyotaka asks if they are going on a date. This prompts Karuizawa to ask if Kiyotaka and Satō are going on a dating each other, saying that going out on Christmas would cause people to see them as a couple, which suddenly causes Satō to be worried about inviting Kiyotaka out on such an important they for couples, Kiyotaka plainly replies if he didn't like it he would have rejected her offer of going out today causing her to become embarrassed. Karuizawa teases Kiyotaka for liking Satō, she suddenly suggests that the 4 of them go on a double date, as Karuizawa and Satō talk about a double date, they both seem to be excited about the prospect of it. Hirata thinks that they shouldn't interfere as they would each have their own plans and suddenly joining them would be difficult but Karuizawa insist that it will be interesting continues strongly suggesting that they should have a double date. Hirata relents and says that if it's okay with Satō and Kiyotaka then it is okay with him. Satō says it sounds interesting and hands the baton to Kiyotaka. Kiyotaka thinks many different things, especially about which choice would be better, or how feasible would it be to suddenly add more people to their already made plans. With him as the last person, to decide he finds it hard to say no so he goes along with the double date. With that decided, Karuizawa asks them what they were planning to do first, Satō tells her they were planning to go watch a movie, Karuizawa tells them that they were going to watch the same movie. They check the reserved tickets and find that they are watching the same screening. Kiyotaka thinks that is too much of a coincidence but since the seats were not next to each other, he thinks maybe they were just lucky.

The 4 of them start making their way towards, Keyaki Mall. Along the way, Karuizawa continues to tease Kiyotaka about them looking like a couple saying that maybe they have just been hiding their relationship. Satō denies it again, and Karuizawa confirms that Satō doesn't have a boyfriend which Satō confirms. Kiyotaka finally understands Karuizawa's intentions, he realizes that the double date idea was probably pre-planned. He thinks that right now the problem is he doesn't really no what to talk about with Satō so there is a long silence as they are walking. Karuizawa gives him a look which only lasts for 1 second, and Kiyotaka guesses that what she is trying to tell him is that: 'Isn't it tough always pretending to calm and collected'. With just his eyes alone, he replies that he doesn't really know what to talk about, Kiyotaka thinks that what Karuizawa was saying was just his imagination and might not be right. As it turns out, Karuizawa receives his message and asks Satō if maybe Kiyotaka doesn't know what to talk about. Hearing this, Satō starts talking about what she likes such as Idols and what kind of music. When Kiyotaka is asks what kind of music he likes, he thinks answering with classical musicians would be a bad answer so he talks about a song he heard in a popular movie. His answer makes Satō happy and she offers to lend him a CD of the artist sometime. The conversation shifts to club activities, Satō compliments Kiyotaka's speed and that he was faster than Manabu at the sports festival. Karuizawa interjects and says Kiyotaka was slower and maybe he just ran with someone slow. She further says, that Kiyotaka looks weak in a fight and is probably a heartless person who doesn't check up on people precious to him who could be sick in bed. Kiyotaka thinks she sounds really angry when she says it, but Satō defends him saying she believes that Kiyotaka is very kind and wouldn't do something like that, Hirata agrees with Satō and Karuizawa replies that if only she thinks that, she becomes the bad guy. From her words, Kiyotaka thinks she maybe proposed the double date as revenge so she could interfere in his relationship. Satō then asks if Kiyotaka is troubled with the school rules of no contact with the outside world. She tells him that she misses her pet back at home, and wishes she could keep a pet at school, while they are talking happily about pets, Kiyotaka is thinking about why the rules don't allow pets, he realizes his musings are useless and that girls don't want to hear about his logic. As the conversation progresses, Satō wants to ask a question, but can't seem to get it out. Karuizawa jumps in and asks what kind of girl does Kiyotaka like, Satō agrees with her and tells him she wants to know too. He says he likes cheerful girls, which surprises Satō. He thinks since both Karuizawa and Satō are cheerful girls him saying that would not affect them. Karuizawa then asks if maybe he likes girls that are both cheerful and adult like. He replies that since he is the quiet type he thinks it's better to have someone who can pull along the conversation. Then Karuizawa asks how he feels about Horikita, Kiyotaka thinks her question is weird because Karuizawa is one of the few people who knows what he relationship with Horikita is, and looking at Satō he thinks that she wants to hear the answer. He then realizes that Karuizawa is asking questions on Satō's behalf to help her, but he still doesn't know whose idea it was to go on a double date. Karuizawa begins attack Kiyotaka by insinuating that maybe he is just keeping Satō around because he can't get Horikita. He asks if he seems like that kind of person who is skillful enough to do that. Karuizawa says he is but Satō defends him saying he isn't like that. Seeing that Karuizawa agrees but follows up with another attack asking if about how close he is to Kushida and how most guys want to date her. Kiyotaka deflects the question by asking Hirata if he wants to date Kushida. Hirata saves him by once again confirming with him that right now he isn't interested in anyone. Kiyotaka praises Hirata for saving his ass from the line of questioning. At that moment, someone ask for the 4 of them. They are approached by Nagumo the current president of the student council, who has brought with him, the vice president Ikuto Kiriyama and some members of the student council including Ichinose. Nagumo wants to have a word with Kiyotaka because he is interested in him, and Hirata who knows Nagumo from the soccer club, asks what he wants with Kiyotaka. Due to his position, the 4 1st years find it hard to deny the request. Nagumo asks his friends to go on ahead, and they talk about how fast Kiyotaka is wanting to test Kiyotaka further, Nagumo grabs Kiyotaka by the arm. This surprising everyone but Karuizawa is the first to react, to defuse the situation, telling Nagumo that his face is scary while laughing. Nagumo apologizes for scary her but doesn't release Kiyotaka, he tells him if Manabu sees something in Kiyotaka, he must be right because Nagumo rates Manabu very highly. Nagumo asks Kiyotaka to be his playmate after Manabu graduates from the school since he will get bored. Kiyotaka asks one question before he leaves, what kind of changes was he going to make with the school. Nagumo tells him that he wants to make the exam more like virtual games, with that he leaves. Satō says he is amazing since the student council president has his eyes on him, but Karuizawa says Hirata is much better and is smarter, which leads to Satō defending Kiyotaka. He then thinks that the plan for the rest of the day, Karuizawa is going to continue putting him down so Satō can bring him.

At the movie theatre, the girls go to the toilet leaving Hirata and Kiyotaka alone. Hirata thanks Kiyotaka who his help with Karuizawa but Kiyotaka replies he hasn't done anything worthy of thanks. Hirata also thinks that very soon Karuizawa won't need him anymore because she hasn't needed him in a long time, although today was a surprise. Kiyotaka thinks that Hirata has 0 feelings towards Karuizawa and is simply looking out for everyone's interest. Hirata asks if Kiyotaka is going to start dating Satō after this, he is about to say no but changes his mind and says he doesn't no yet. Hirata thinks finding someone to date will be good for him and that the reason he hasn't found anyone is not because he isn't popular but because he hasn't found anyone he wants to date yet. They change the conversation to Nagumo, as Kiyotaka wants to learn more about him, Hirata tells him he has many good ideas during his time in the soccer club, but apparently students who didn't agree with his ideas were not only forced out of the club but also the school. Hirata asks if Kiyotaka is planning to join the student council but he says not at all. They are discussing class D and whether they can work together to aim for class A as a class before the girls return ending the conversation. After the movie, the 4 head for lunch and decide to do a round robin of questions. Karuizawa starts by asking him, if he has dated anyone, thinking that he would sound lame if he sound he hasn't dated anybody, he says he isn't dating anyone now. Karuizawa points out that only those who haven't ever dated anyone adds now and confirms it by asking again but this time asking if he has dated anyone in the past. He says no, Satō look happy at his answer and says its all right it he has dated anyone before. Satō asks the next question, what kind of hair styles does he prefer, he says it depends on whether it suits the person. Which Karuizawa says is just a model answer, Hirata comes in an says he thinks that's best too. Satō agrees with his answer and Karuizawa acting as a good girlfriend agrees with Hirata. Now it's Kiyotaka turn to ask a question but instead of asking Satō a question he wants to know if Hirata is aware that he is popular. Karuizawa calls him out on it, but they reach the restaurant before they can continue. At lunch Kiyotaka is amazed that the table is set for 4, Karuizawa says they requested them to add more people while they were in the toilet, Karuizawa proudly says that she is an expert in these things. Kiyotaka calls her a liar using his eyes, and Karuizawa shots him a look back which Kiyotaka imagines is her saying that she doesn't want to hear that from someone has has never dated anyone before. They continue the questioning from before and Kiyotaka asks Satō what her interests are. She says she is into fashion design, and hopes to get a job in fashion if she can graduate from class A, Kiyotaka and Karuizawa both say they will probably continue studying.

After lunch and hanging around the mall, after Karuizawa and Satō exchange some signals, Karuizawa and Hirata leave to return to the dormitories first. Satō ask if they can walk around a little bit more. Satō asks if he enjoyed himself today, he says yes, but she doubts it because he didn't laugh or smile once the whole day. He tries to convince by saying he just isn't used to smiling but he really enjoyed himself. Kiyotaka thinks he enjoyed himself and hopes that the day won't end on a sad note. As the atmosphere becomes quieter, Satō decides to confess to Kiyotaka. However, Kiyotaka rejects her confessing telling her that he cannot date someone if he doesn't have feelings for them, although he thinks that this is just the surface reason. He tells Satō that even if it was Horikita or Kushida confessing he wouldn't accept the confession, in his mind he also thinks about Airi. He tells her that he isn't mature enough to understand love so he isn't ready to date. She asks if she can ask him out again and he says it was fun and he would like to go out again. He also thinks that he probably won't forget the first time he was confessed for his life. Satō has tears in her eyes as she runs off, not waiting to cross paths with her in the dormitories he lets her run off. During the confession, his phone rings but he doesn't answer it, when Satō runs off, his phone rings again and this time he answers it. The person calling has an unknown number, and asks if he can trust Kiyotaka. He reveals that Manabu told him about Kiyotaka and he would like to meet. Kiyotaka tells him he has something to do first as he looks at a bush where someone is hiding. They agree to meet in 20 minutes. Kiyotaka calls out to the person in the bushes, telling her that she will catch a cold if she stays there, but she doesn't come out. Kiyotaka says he is going to prompting her to ask how long did he know she was hiding there. Karuizawa comes out of the bushes as he says he knew from the start. Karuizawa asks why he rejected Satō when there was nothing wrong with her and he looked liked enjoyed the date too. Kiyotaka reminds her that it was her who said dating someone you have no feelings for is terrible, but she replies that he could have grown feelings for her. He admits that he thought about dating Satō which makes Karuizawa angry since he rejected her even though she worked so had to get them together. Kiyotaka continues to give reasons like he can't have a normal relationship, but Karuizawa says, that he wants a normal relationship though to which he also agrees. So she once again keeps asking why he rejected Satō. He even admits he wouldn't have minded getting to enjoy the fruits of having a relationship, Karuizawa calls him the worst but he asks her if she herself doesn't want to try it herself, she replies that it depends on the person to which he agrees. Still not satisfied with his answer Karuizawa keeps pressing him, finally he asks her to let him make her own choice but she gets made again and asks him why he rejected Satō. He finally tells her the real reason, because she is here with him he didn't accept Satō. He thinks that accepted Satō would have decreased her her trust in him and increase her anxieties, because she would feel like Satō would replace her. He confirms that Karuizawa is a much better at adapting to situation than Satō from the way she handled Nagumo during the date. While he is thinking about Karuizawa's usefulness to him, Karuizawa who thinks about his answer, expresses that Kiyotaka really only thinks of people as tools, seeing right through his thought process. They start walking together, although Karuizawa is walking in step slightly further so they do not look like they are together. She asks him to apologizes for what happened with Shiho Manabe, and Kiyotaka says he will make it up to her later, but she wants him to make it up to her now and asks him what was happening with Nagumo. He decides that he should tell her now and tells her he is going to meet a 2nd year who opposes Nagumo and invites her along.

Kiyotaka turns off his fun as he reaches the meeting place. He and Karuizawa wait for the 2nd year to show up. Karuizawa thinks that the 2nd year can see their identities and leave without showing their face but Kiyotaka thinks that because Karuizawa is with him and his phone is off, the person has to show up to confirm whether he is the person the 2nd year is supposed to be meeting or a random couple hanging out on Christmas. The vice president Kiriyama shows up and asks who Karuizawa is, Kiyotaka replies a partner he can trust. They begin talking about Nagumo and why Kiriyama wants to bring him down. Kiyotaka asks if Nagumo really has control of all the 2nd years. Kiriyama tells him he has although some may not like it, Karuizawa thinks it's weird since they should all be fighting to be in class A. Kiriyama explains that, Nagumo promised a revolution and that he would bring any student from any class with good abilities into class A. Kiyotaka explains that there are students like Keisei and Horikita who are talented but in class D and these students will follow Nagumo on the chance to get to class A. They learn that Kiriyama is from class A but dropped to class B because of Nagumo and is working on the student council as the vice president so he can gather information on Nagumo. Kiyotaka realizes that he really dislikes Nagumo, which is why he is willing to good behind him. Kiriyama tells him that since all of the 2nd years are under his control he looked for rivals in other years like Manabu, and tells Kiyotaka that Nagumo will focus on him once Manabu graduates. Similar, because of the 2nd years aren't willing to defy Nagumo, Kiriyama has to find allies outside his year. Kiyotaka thinks that this wouldn't have happened if he didn't run against Manabu at the sports festival, but since Nagumo already has him in his gaze he may need to do something. Kiriyama says he is willing to pass information but anymore than that he won't do especially if it's against the school rules he leaves the decisions to Kiyotaka to make. He tells him from now on they won't meet but he will send messages using a free account, with that Kiriyama leaves.

Kiyotaka and Karuizawa head back and they talk about what they heard from Kiriyama both of them are not sure what to think of Nagumo. As they walk, Karuizawa asks what he meant when he called her his partner because she thinks Horikita is more fitting of that title. However, he tells her she is just his neighbor and that Karuizawa is much closer to him. She accepts being his partner and Kiyotaka tells her not to expect too much as that would mean making meaning the people after him her enemy too, she tells him when that happens she will protect him too. Karuizawa then asks what kind of middle school did Kiyotaka go and instead of answer he asks her to guess. She guesses that if this was a manga the only thing she can think of is him being raised in a facility to be some sort of agent. Kiyotaka thinks she is spot on but doesn't tell her when she gives up guessing. She promises that she will one day get the answer out of him. He then returns with a question about whose idea was it for a double date, and they both agree that Satō was acting a little weird. She then decides to give him a Christmas present, after teasing him that he didn't get to receive a present from Satō. She says she bought it when she went Christmas shopping with her friends and bought a present for Hirata, he accepts the present. Karuizawa then asks Kiyotaka if it's okay if she breaks up with Hirata even if her value to him drops, he tells her that even without Hirata here value won't drop because she is different from the old Karuizawa. In his mind, he muses that he had also planned for this to happen as well and with this Karuizawa would become more closely attached to him which was part of his plans. Although the double date was unexpected he ended up getting closer to Karuizawa too. Since they are going to break up, she reverts to calling Hirata by his surname but continues to call Kiyotaka by his given name. He asks if it's okay if she continues calling him that, he replies it's up to her. He tells her that from now he will call her by her given name Kei which surprises her. He remembers the package he had bought 2 days prior and takes it out of his coat and says he has a present for her too. He hands her a package with 2 types of medicine and a receipt inside. The receipt shows that it was bought on the 23rd of December at 10.55 am, which makes Kei release that Kiyotaka had wanted to make sure she wasn't sick and actually care if she okay after what happened on the roof. He then explains that he saw her and Satō at the mall so he knew she was all right. She tells him that if he was worried he should have went to see her directly or called her. He replies that he can't simply go to her room, and calling her wouldn't be good as Kei could have pretended to be strong. Moreover since he was the cause of what happened on the roof he didn't want to put any pressure on her mentally. He tells her that he underestimate how strong she was and would need her help in the future, she agrees as his partner. As they walk back Kiyotaka thinks that in this 1 year, the person closest to him was probably Kei and before he knew it she have become some indispensable to him. He thinks that maybe there are friends, and if there was no problems like Nagumo or aiming for class A they could be more than friends.
