Ichika Amasawa

Appearance
Ichika has straight scarlet hair that is tied into twin-tails and laced with red ribbons, and gradient dark-red eyes. She is seen so far wearing formal school attire consisting of an orange blouse paired with an unbuttoned crimson blazer with a blue ribbon, a short-length white sailor striped pleated skirt, and black thigh-highs. Ichika has the seductive charms to even tempt Ken Sudō to believe her words for a moment based on how she conduct herself in feeling him up with one tiny hand movement.

Personality
Ichika has a very mischievous and enthusiastic personality, devilishly teasing every character she has interacted with so far, even when it angers them. Because of that, she was described by Kikyō Kushida to have a rotten, smug, condescending attitude. Ichika is overly playful with her choice of words, not taking what she said in the open seriously when it is all in fun amusement to the former for the latter almost believing it to be true. Ichika has a whimsical manner of doing things, choosing to act according to her impish impulse, not always but sometimes following through with whatever she proposed unless it is of interest to her after careful deliberations. In a way, Ichika was believed to be strictly judgmental, acting quick to change her mind and decision at any moment in time during the middle of negotiations. She is perceptive on understanding what people may think of her based on her action, quickly pointing it out on what to say to that before they get a word on expressing their thought about the former. Ichika can come off as quite provocative with her shrewd remarks, making others feel stingy by the way she acts around them without caring of how others may judge her as.

In that regard, Ichika can be seen as a little bit tolerant to what people's words are towards the former on how they describe her to be such as when Kiyotaka even calls her some sort of demon for doing whatever she pleases recklessly while spending his private points on things. She has a lot of self-confidence and overvalues herself a lot when people requests for her service in making a deal with them. Ichika has a habit of speaking casually with a relaxed tone in all sorts of situations she finds herself in unless the former felt upset and offended by what she heard. She is like a misfit within her classroom where nobody bothers to reach out to the former and befriend her socially. Despite having amazing communication skills, Ichika admits she was still suck at making friends with the people in her class. Nonetheless, Ichika is thoughtful about her way of life back in the White Room and the peers she got to know there that matters a lot to her more than Kiyotaka being her idol of worship. She dislikes seeing outsiders like Kikyō Kushida get in the way of expelling Kiyotaka as people like them have no right to interfere except for those who're rightfully involved such as herself.

Background
Not much is known about Ichika's history except for the fact she was raised in the White Room as a member of the 5th generation. In Volume 3 of Second Year Arc, she said that her relationship with Ayanokoji went beyond love. It was later revealed in her monologue that she was born using in-vitro fertilisation, from the parents that, according to her, are said to be geniuses. She had described her life in White Room to be monotonous where a talented person like her wasn't welcomed.

2nd Year Volume 1
Once she enrolled into Advanced Nurturing High School, Ichika was supposedly tasked by Acting Director Tsukishiro as the White Room Enforcer to expel Kiyotaka Ayanokōji. Among the few first-year students to know, she was apparently one of them who is aware of the 20 million private point bounty on Kiyotaka.

On Tuesday during the second day of the Partner Exam, after overhearing that they were looking for a good partner, Ichika approached Suzune Horikita, Kiyotaka, and Ken Sudō in Keyaki Mall, offering to partner up with one of them for the special exam. Ichika had been carefully watching how their conversation will play out from the first floor until she steps in and ask them about it. Ichika reassures Suzune that she was not eavesdropping on the three, reasoning that the former had decided to call out to them after overhearing how they're looking to find a partner for Ken. She and Suzune would formally introduce each other by their name, class affiliation and academic ability rating. Upon hearing Suzune's academic capability, Ichika voluntarily asked Suzune if she can be her partner in this special exam while promising that they together can reach the top spot. Kiyotaka noted how Ichika didn't bother to question Suzune's background whatsoever and chose to consider cooperating with her anyway. However, Ichika was turned down by Suzune who the latter suggests she be the partner of Ken instead. Despite already knowing thanks to OAA app, she inquires what the ranking of Ken's academic ability rating is before considering joining hands with him which Suzune states it's an E+. Through this, Ichika easily guesses that Suzune wants a lowly-academic student like Ken to pair up with her so that she can save him from possible expulsion. Ichika doubts that she has a good chance of taking the top spot in the exam by being partnered together with Ken, believing they will end up a little below average.

Although there's nothing for Ichika to get from working with Ken, she didn't mind helping out her upperclassman since Suzune was the one asking for her assistance. Ichika then shifted her sights in Kiyotaka's direction, questioning Suzune if he needs a partner too besides Ken. While Suzunes offers Kiyotaka with a C+ academic ability rating up to her as a partner, Ichika states that she has no intention of agreeing to cooperate with him either. Despite initially offering to pair up with Suzune, Ichika considers her upperclassman's offer of partnering with either Ken or Kiyotaka to have certain conditions that must be met first before going through with their partnership deal as she has the right to call the shots. Since Suzune has no idea what was meant by her statement, Ichika states that she has been super concerned about what to do during this exam, wondering if it was the right decision for her to aim for the top spot and study as hard as she can while considering pairing up with somebody smart like Suzune. At the same time, if not that, Ichika wonders maybe she should just go with the flow and tackle the exam without having to worry all that much. On that note, without having to care a lot about the exam, Ichika admits that she may as well look for someone who she has an interest in and pair up with that person if they happen to be a powerful guy. In other words, Ichika declares that she has a thing for liking strong people and asks Ken to prove his strength by brawling with the other second-years, but Suzune declines due to school rules with regard to violence between students. To Ichika, what she wants from a strong person is not their mental strength, but rather their physical prowess mainly, understanding that perhaps Ken do fit the bill and guesses he is likely someone who has participate in a lot of sports. No longer interested in the person's academic ability, Ichika then turned and pointed her finger directly at Ken, questioning if he has what it takes as a powerful guy to partner up with her.

While so, Ichika reached out her hand to caress Ken's cheek, leaving him to nervously ask her if she was really okay with someone like him not being smart. Ichika reasons with Ken that she is fine with him being her partner as long as he happened to be that strong person she desired. With that, she proceeded to trace her slender finger across Ken's chest, mesmerizing him with her bewitching appearance and action. When Ken confidently states he is indeed powerful, Ichika expressed she doesn't hate that kind of confidence in a guy like him. With Suzune still feeling uncertain as to what she was referring to, Ichika states it means what it means as she has a liking for powerful dudes who are good at fighting in hand-to-hand combat. Ichika reasons that it has to be somebody who is actually nice and strong who she can accept as her partner. When Suzune tries to vouch for Ken's physical strength, Ichika doubts otherwise thinking that the upperclassman's words alone are not proving to be convincing and states she has to see it with her own eyes to believe. In order to have Ken prove his worth, she wants Suzune to go gather up all of the strongest guys in the second-year and have them arranged a fight with him. She states that whoever emerge victorious in the end will have the right to be her partner even if it is not Ken. When negotiations was about to break down, she didn't mind that that they forget this entire conversation ever happened in the first place. Though Suzune questions how serious she was about that condition, Ichika reaffirms it to be what she desires emphasizing that it has to be someone who is powerful enough for her to be pair with. Ichika initially expresses her sweet excitement that they were going to follow through with her offer of arranging a match among the second-years. However, Suzune put forward a promise of her own as an important stipulation whereby if nobody shows up to the fight and challenge Ken, Ichika will have no other choice but to partner up with him.

Understanding the verbal promise that she will be Ken's partner if he wins by default, Ichika nonchalantly accepts Suzune's stipulation and have them be the ones to arrange the location of the duel to avoid letting the school catch wind of their action. To seal the deal, Ichika typed out an advertisement message of the fight on her phone as a sign of confirmation. Before sending the message though, Ichika suddenly turned off the screen of her phone and put it back into her pocket to show that she was not really fine with the idea whatsoever. If anything, according to Kiyotaka, it was as though Ichika was trying to sound the three out with this deal she proposed as a way to test them. Having already seen Suzune and Kiyotaka's attitude towards Ken's strength and his physique, Ichika decided to change her mind about her proposal, stating that she knew no one would likely go out of their way to show up to fight Ken himself even if an advertisement message was sent out. Through this conversation, she had more or less came to understand how powerful and physically top-class Ken is among the second year-students. She had managed to reach a conclusion that there was no real need to compare the second-years to Ken through a fight at all. Suzune asked him if she was just toying with the three of them, Ichika said it was nothing like that, stating how the match with Ken won't be fun since nobody is willing to battle him while admitting it was her intention to see and confirm for herself who was the strongest among the second-years (excluding Kiyotaka). Thinking that Suzune is mad at her, Ichika pressed her forefinger to her lips as she thought it over for a moment, contemplating she ought to give them a second chance to convince her to partner with Ken as an act of forgiveness for her rejecting the proposal from earlier. Ichika then changes her condition by saying that she would liked a boy that could cook a super tasty meal, asking Ken if he can make something like that to impress her.

Ichika comments that he not only needs to prepare a home-cooked meal that is scrumptious to her, but he must be sure to make what she asked him to do. Hearing how Ken has never cooked a meal in his lifetime before, Ichika considers retracting her offer right then and there until Suzune cuts in the conversation stating that she wants to handle the task of doing the cooking. However, Ichika was against the idea of having a girl becoming a cook for her and desires a guy who is capable of cooking for her rather than someone of the same gender as her. Ichika conveys her reasoning that there was no point in herself partnering at all if it's not a man that possesses good cooking skills. Ichika suggests Suzune give up and go find a male from Class 2-D in Ken's stead, provocatively teasing the latter of thinking if the former won't be his partner no matter who cooks for her. Ichika went on to say that maybe Suzune should train Ken into becoming a cooking pro, doubting whether she will have enough time to teach him the necessary skills and warns that the latter need to hurry up and make it happen before the former finds and decides on a partner herself. Seeing that they were unable to give her an answer or come to a decision, Ichika spoke up once again and decided to offer Suzune and the two a small concession to her proposal. Ichika states how she was willing to give them a special service that as long as there is a man in Class 2-D who can satisfy her appetite and tastes, it will be more than enough for her to consider being Ken's partner other than him being a powerful dude and all regardless of whether it was another guy doing the cooking or not. More so, Ichika noticed that by partnering up with a male who was not only a veteran fighter, but having a skilled cook as well happened to be similar to the conditions of her previous proposal and this deal combined as it has what she was looking for in a man. This in turn, leads Suzune to have Kiyotaka be selected as the one man to cook for Ichika rather than Ken.

Hearing Suzune's choice, Ichika admits she is fine with whoever cook for her as long as it is a guy doing the task, wondering if Kiyotaka really possesses the cooking skills and informs him that the former won't believe his words until she judge the meal for herself. In other words, Ichika lay out her new condition as follow, that if Kiyotaka could get the former to enjoy eating the food he made, she wouldn't mind the idea of becoming a partner to Ken in the special exam. Just as soon as Kiyotaka affirmed his promise to cook for her, Ichika clapped her hands in acceptance of their new arrangement. Making an ultimatum, what Ichika proceeded to do next was then egg Kiyotaka to come with her immediately and show the former what he really is made of with his cooking skills. As she was looking to find out whether or not Kiyotaka was actually a skilled cook as he believes himself to be, Ichika didn't want to give Kiyotaka an opportunity to go and learn cooking by extending the time of the deal after it is created. However, before she could move forward with carrying out the deal, Suzune stopped Ichika in her tracks, asking the latter to give them a little more time as Class 2-D is busy competing with the second-year classes to find first-year students who can they used to pair up with their other classmates that needs help besides Ken. With that, Suzune firmly rejected Ichika's desire to have her home-cooked meal presented to her now for this day. When Suzune suggested they hold off by postponing their deal until Friday after school, Ichika understood the situation concerning Suzune's class and put forward with a different offer. Rather than go with the one suggested by Suzune, Ichika rigidly presented us with her own terms in rebuttal. Ichika initially proposed Kiyotaka's cooking can happened later tonight if they are down with her idea as she can't help but feel iffy waiting too long on Kiyotaka to cook until during the weekend. Ichika reasons that she might end up losing out on her chance to partner up with another upperclassman if the deal with Kiyotaka doing the cooking is unsuccessful.

However, since she recognizes that her meeting with the three was a fated encounter, Ichika instead decided to give them a day to prepare themselves in fulfilling the deal. Ichika reminded the three that if Kiyotaka can't served her a home-cooked meal after school by tomorrow, she tells them that the deal is called off and be asked to pretend their conversation the previous day never happened with the former. According to Kiyotaka, this was probably the very last compromise Ichika was willing to make with the three of them. As a result, Ichika's proposal was readily agreed upon by Suzune after considering how many chances they've been given to accept her offer. In turn, Ichika made a verbal promise to Suzune that she will uphold to these new conditions by partnering with Ken once they fulfill their end of the deal whereby Kiyotaka satisfied her with the meal he cooked. Since the deal has been officially arranged, Ichika informs Kiyotaka that the two of them should meet up in front of Keyaki Mall at 4:30 PM tomorrow after school when their classes are over by then. Ichika briefly explains that the reason for going to such a location rather than in the dormitory was solely because she wants to keep the dish she was planning to have him make for her a secret by having them go shopping together to purchase the ingredients and tools themselves. Ichika was essentially saying that everything from what Kiyotaka buy in the store to how he cook and prepare his meal was going to be all part of her analysis and sorting out her thoughts on his skills. Ichika refuses to take Suzune along with Kiyotaka, reasoning that the latter will likely attempt to help him out through their hidden eye signals or some sort to each other as the former states this matter is specifically between herself and the guy who she will have a strict judgement for. Seeing that Kiyotaka was okay with her demands, she bid the trio farewell and parted ways with them soon after.

The next day, on Wednesday during the third day of the special exam, Ichika met up with Kiyotaka Ayanokōji at the entrance of Keyaki Mall. Admiring the fact that he had already appear and waiting before she could arrived within the meeting place and appointed time, Ichika lavish praises for him for a job well done in coming early and not doing something excessive like messing with his phone or making a call. As soon as the two joined up and entered the mall together, Ichika went with him to buy various essential cooking utensils and ingredients. Recalling hearing the details from her classmates of where the goods are being sold, Ichika voice her intention of not holding back on what things to get and have him used in preparing to cook her meal. Ichika walked straight into 'Hamming', a shop specialized in selling home goods and other daily necessities, and picked up a blue shopping basket that she had found near the entrance of the store. Afterward, she stopped by the section where the kitchenware was on display, looking to get her hands on a specific specialized equipment among the cooking utensils. Curious about her action, Ichika was asked by Kiyotaka if she had ever done any cooking of her own before to which the former admits she never did. Ichika reasons that she is the kind of girl who would rather let the others do the cooking and making things for her instead of doing it herself. She explained such before stopping in her tracks, having seemingly arrived at her destination. Turning her gaze away from Kiyotaka, she fixed her eyes upon the shelf of goods in front of the two and began deliberating on what to purchase. Having made up her mind, she confidently suggest Kiyotaka that he will need a cutting board, a kitchen knife, a fruit/petty knife, bowls, a whisk, a pot and a ladle.

Going to each shelf, Ichika grabbed and tossed every one of the items aforementioned into the shopping basket one after the next as she listed them out loud to Kiyotaka. Ichika informs him that these high-class, expensive items Kiyotaka will be purchasing are exclusively used whenever he cook for her sake only. While gathering the essentials, she spent the time having a casual, relaxed conversation with Kiyotaka like how every skilled chef such as himself need to have the right high-quality items ready to make the best food possible for her. Noticing that Kiyotaka was considering to utilize them from now on since they're better than his low-quality ones, Ichika reminds him once again that the items are exclusively reserve for him to use in cooking just for her and not for anybody else including himself. When Kiyotaka badmouths her as a demon, she shrugs it off provocatively stating that it is his decision whether or not to go through with buying her items as the former can call quits if he wishes. According to Kiyotaka, Ichika had grabbed onto his weakness, fully aware that there was no way he could refuse her offer, dancing in the palm of her hand as she guide him along to keep buying the necessary things. He had no other choice but to agree on all her conditions and freely buy whatever she wants if it's to help his classmate Ken successfully become Ichika's partner. Ichika questioningly asked Kiyotaka if he thinks she is a bad girl to which the latter admits he wouldn't say that. Ichika fixed her gaze on his eyes and then, having seemingly come to realize something, smiled broadly while telling him that everything should be okay. In the end, it was said that she had Kiyotaka alone paid for all sorts of luxurious things along with the ones already specifically mentioned to be carried in Ichika's shopping basket. Particularly, she made Kiyotaka spend a lot of his money on them that were easily worth and costed him over 15,000 private points. Thereafter, she and Kiyotaka went to the supermarket next to buy the ingredients when they're done obtaining the cooking utensils in the store.

When she is finished picking out the ingredients for him to buy with his money in the supermarket, Kiyotaka's spending amount increases up to around 20,000 private points overall. Kiyotaka noted how she had went out of her way to have him purchase all sorts of ingredients ranging from the likes of vegetables to meat to fruit, and everything else in between them. Among the ones Ichika had chosen for Kiyotaka to get was notably the nam pla and chili peppers. With everything taken care of, she eggs Kiyotaka to lead her into his bedroom, feeling to eager to test his cooking skills. As a result, they proceed to head towards Kiyotaka's room at the second-year dormitory building, which was the place to have him show off his cooking to her. While heading there, Kiyotaka questions her why she was fine with letting a stranger like him who she doesn't know a thing about cooked her a meal, Ichika states that her own action was not at all different from going out to eat in a restaurant. She explains that Kiyotaka making food in his kitchen was the same as someone being in the restaurant doing the exact thing like him when preparing a meal for her. Ichika reasons further that it should be fine if the chef cooks in front of her, stating how she can get a better look on his face and how he goes about making it and all while needing to check and make sure if he was sanitary with his methods. She then points out how some kitchens in restaurants are hidden from her sight along with other sketchy places having stuff like bugs crawling around everywhere on the floor. Ichika put forward this sort of opinion that, as long as she witnessed it with her own two eyes, it did not matter to her who made the food, even if they were a stranger she encounter. Ichika even told Kiyotaka that she had a good understanding of how their school works like if the former ends up without any private points left, she will have to live sparingly. She said that Kiyotaka being there for the former as her cook is enough to get by anything without worrying regardless.

Essentially, she was looking to secure a reliable meal ticket in the event of an emergency like running out of points. This implies to Kiyotaka that if he satisfy her hungry desires of his food, she will continue stopping by again to have him cook for her once more. Since Kiyotaka understands where she is coming from with her words, Ichika asked him to be mindful of the fact that he needs to make a delicious dish to impress her as the former views herself to be a very picky eater and will call off the deal if it doesn't meet her expectations. Not before long, she and Kiyotaka soon eventually arrived at the entrance to the second-year dorms and felt it was somewhat unsettling while looking up at the building with her hand placed above her brow. However, upon closer inspection, she regarded it to be the same as the first-year dorms, after taking a good long look at the exterior of the building and surveying the inside of the lobby. Ichika casually waved to the onlooking upperclassmen as she and Kiyotaka passed them by while walking over to the dormitory. Once she entered his room, Ichika found Kiyotaka's room to be nice and tidily clean while pardoning herself for the intrusion. Waiting for him to settle down and get ready to cook, she was prompted by Kiyotaka to take a seat and then given a coffee to drink from in the meantime. Ichika picked up the remote control that was placed on the table and began to flip through the TV channels to watch. She warns him to not try and look up anything on his phone as it's prohibited under her rules and requirements. She asked him if he was scared of failing to win her over but Kiyotaka states he had no problem with handling the cooking whatsoever, leaving Ichika to praise his confidence as wonderful and informs him that a good cook is somebody who knows the recipe by heart. To get Ichika to feel at ease, Kiyotaka decided to leave his phone on his bed before heading off to the kitchen to make the meal. After she nodded contentedly, Ichika picked up her cup of coffee and took a sip.

As Ichika begins to relax inside, the former pleadingly states that she would liked to eat Tom yam kung, a Thai cuisine dish which Kiyotaka has been tasked to make by her. Along the way, she was told by Kiyotaka that there was no real need to use a whisk or a petty/fruit knife to make Tom yam kung but Ichika responded stating that he may only need one of those two kitchen utensils to help him peel an apple for her. At the same time, she informs Kiyotaka that the latter can feel free to enjoy eating the leftover ingredients all he want while reminding him about the rest of the utensils purchased in the store will be used next time when she visits his room again to have him cook for her. Once the cooking was over, Kiyotaka prepared the home cooked dish and presented it to Ichika along with the freshly cut apple slices. She expresses her amazement by how Kiyotaka skillfully handle peeling the apple with his skills of using the petty/fruit knife, complimenting the latter and giving him full marks for the perfect job he was doing. When Kiyotaka notices the cilantro was not one of the things she got him to buy to prepare Tom yam kung, Ichika admits she likes the ingredient but didn't want him to get his hands on that since it will only served to help make the identity of the dish seem obvious. She had been on guard with the choice of selecting specific ingredients, having deliberately chosen to leave out the cilantro intentionally on purpose. That is, Ichika had taken steps to prevent Kiyotaka from pulling any cheap tricks on her as she had done so in order to avoid showing him an opening. With his task completed, Ichika asked Kiyotaka to sit down right in front of her so that she as a judge could give her verdict on the dish overall. Ichika proceeded to conduct the taste test when she slowly carried a spoonful of hot Tom yam kung into her mouth and gulp it, eating every last bite of the dish provided before her.

After she got finished eating, Ichika clasped her hands together and thank him for the meal, seemingly satisfied with what he made. She judge the taste of Kiyotaka's dish as just being barely good enough but felt it was delicious nonetheless, vowing to try the meal again when they have time. Soon, Ichika volunteer to do the cleaning work by picking up her bowl, spoon, and the other dishes on the table and headed over to the kitchen. She didn't just place the dishes in the sink, but instead began tidying up the entire kitchen. To pay the favor back to Kiyotaka who was giving her hospitality in his room, Ichika reasons this was her way of expressing gratitude and service, considering she was the one who forced him to cook for her. Reasonably so, Ichika asked Kiyotaka to sit back and relaxed outside the kitchen area, voicing how despite her being terribly bad at cooking, she can still do a good job in cleaning and tidying things up. Meanwhile, she would lie and falsely claim to him of how the former had used to always help out in doing something like that with her supposed mom. Realizing she has yet to announce the results of the taste test, Ichika admits it is a bit tricky for her to reach a definite decision. As she thought about it over in her mind, Ichika was not happily please with the position of the ribbon holding up her right ponytail, as she unfastened the ribbon and began to tie it back on, using her reflection on the screen of her phone like a mirror to see better. Not long after, just as she finished tying back up her hair, Ichika delivered her final verdict whether he pass or fail her taste test. While his cooking technique and her taste on the food wasn't terrible or bad, she gave him a passing score despite having been really picky about it. Ichika states that depending on how hard he works with improving his cooking from now on, she will consider returning to Kiyotaka's room and eat again next time around if the latter's effort paid off. Although Kiyotaka didn't pass her taste test, she does in fact recognizes his ability to cook a satisfying dish.

Not only that but considering how much private points he spent greatly buying expensive utensils and ingredients after letting her eat his dish for free without charge, she decided to repay his hard work with her decision of accepting the condition by Suzune. To that end, she agreed to pair up with Ken Sudō for the Partner Exam out of renewed respect for Kiyotaka's efforts. Before long, after cleaning up his kitchen area while feeling content with its tidy state, Ichika came back to the living room where he was at. She then took out her cellphone and officially submitted an application to become Ken's partner, showing him the screen as real proof that she actually fulfill her end of Suzune's deal. She was alright with waiting on Ken to accept her pairing application later during the day after getting told by Kiyotaka that he was busy taking care of his club activities. She light-heartedly welcomes his gratitude, asking him to continue lavishing praises for her as much as he wants about the former having agreed to work with Ken as promised. Ichika tells Kiyotaka that she cannot act as an intermediary for Class 1-A and Class 2-D when it comes to negotiating on the idea of pairing students across their two classes. Ichika reasons how she was not really close friends with any of her classmates whatsoever, saying it has nothing to do with herself trusting either him or Suzune but not being of help to them. Ichika support this claim by asking Kiyotaka to recall the time where she alone was the only person to have met up with him, Suzune, and Ken. Before finally leaving and parting ways with him, Ichika apologizes to Kiyotaka that she is unable to help play the role of his intermediary due to her own failure to establish friendship with her classmates might be because of how she lack delicacy or some sort, stating that the former is not the type to sugarcoat her words. When Ken responded to her offer before the end of the day, Ichika's partnership with him had now been set in stone and they were set to beat the exam without neither one of them succumbing to expulsion.

On Friday during the fifth day of the special exam, she visited the second-year dormitory and arrived at the doorsteps of Kiyotaka Ayanokōji's room in the dorm's lobby, ringing the doorbell to notify him of her arrival. Ichika playfully waved her hand at the camera with a wide grin on her face to show Kiyotaka of her presence. Much to her surprise however, Ichika was angrily screamed at by Kei Karuizawa who asked her who she was, leaving the former to jump back in shock and ponder if she had went to the wrong room 401 that Kiyotaka was staying in. Noticing that he has a girl company with him in his room, she questions Kiyotaka if she should visit at a different time and date, wishing to come up and talk with her upperclassman face-to-face. With Kei's willingness to let her into his room, Ichika was shortly a minute later allowed in by Kiyotaka after freely getting on the elevator to reach the 4th floor and having ring the doorbell to show that she is standing before his room. Once she step foot into his living room and greeted him, Ichika stated that the former came as she had lost her favorite hair rubber and needed to go retrieve it. She introduces herself to Kei face-to-face, guessing that the latter is Kiyotaka's girlfriend and was likely in his room with the purpose of studying with him. Kei does the same likewise by introducing herself too, and asked Ichika about her relationship with Kiyotaka, and she told her that Kiyotaka was her personal chef. She later teased Kiyotaka for looking at her butt while she searched for her hair rubber under his bed, making Kei annoyed by her action. Realizing that the hair rubber is not beneath his bed, Ichika decided to search the kitchen area instead with permission from Kiyotaka as she believes the former left it there last time when washing the dishes. She recommends Kiyotaka remain in his living room and look inside the dressers as well beside the bed for her missing item. Eventually, she ends up finding her hair rubber that was in the kitchen all along, explaining how it must've fallen into the gap between the counter and the fridge during that time when she was still alone with him. Not soon after, she apologized to Kiyotaka for her teasing and interrupting their intimate moment. What she got of directly meeting Kiyotaka alongside Kei was he isn't someone to be underestimated, learning the fact that he got himself a cute girlfriend. Before leaving his room, Ichika suggests Kiyotaka that he was allow by her to have Kei accompany him next time whenever the latter cooks a meal for her and the three of them eat together.

It was later revealed in that she had played a role in supporting Kazuomi Hōsen's plan to expel Kiyotaka, but the motives behind her decision and action remains unclear. Through Kiyotaka's attempt to gather information regarding Ichika's movement, he learns that according to the store clerk, just as Hōsen was about to finish paying for the knife, she reached out and stopped him from going through with the purchase. Although Hōsen was the one who came up with the knife strategy to try and get him expelled, Ichika was none other than the one herself who helped refine that plan to perfection. The reason behind why Ichika and Hōsen had chosen to use this expensive petty/fruit knife Kiyotaka bought for her was solely because it was the only one in the store that came bundled together with a sheath, making it the most convenient option available to conceal the weapon. Ichika gave Kiyotaka's recently-purchased knife to Hōsen, deliberating that if her conspirator were to stab himself with his own knife, it would naturally lead to problems once the school investigated what happened as she helped remove the flaws of his strategy. Back when Kiyotaka went shopping with her for kitchen utensils, Ichika had managed to locate and pick out this exact expensive knife without searching for it at all, even though it was supposed to be her first time in that store, implying to Kiyotaka how she must've already went with Hōsen to the store beforehand. Furthermore, back on Friday, Ichika had shown up at Kiyotaka's room saying that she had lost her hair rubber, but that had been nothing more than an excuse to recover the knife. Kiyotaka felt it was natural to assume that Ichika had planted the knife there ahead of time or simply lied about leaving it there whatsoever. On the other hand, since there was a possibility that Kiyotaka might notice how the knife was missing if she recovered it too soon, he deduced that Ichika must've chosen to wait until the right time, delaying her move until the last possible moment. After which, she just needed to proceed forward in retrieving the knife out of his room without getting any fingerprints on it and hand that weapon to Hōsen before her conspirator could carry out his strategy against him.

2nd Year Volume 2
In her side story, Ichika was revealed to have been keeping an eye on Karuizawa Kei from Class 2-D for almost two weeks, stalking her when she go to the café, the karaoke, and all over the Keyaki mall. Although she thought it was almost a waste of time to do since Kei was mostly hanging out with her friends, she waited patiently long enough to notice the girl's movement to be unusual at this time by returning straight back to the second-year dorm. Seeing that, Ichika intuitively rushed out to the lobby on the first floor and watched her as she went inside her own room. After waiting for a bit, Ichika took the elevator and arrived on the floor where Kei's room was in and stood on standby again close to the emergency stairs until Kei comes out of her room. Confirming that she was ready for the secret date with Kiyotaka and already gone to his room, Ichika later went back to her own living room to get dress with her favorite cute, casual clothing attire in preparation to seduce Kei's boyfriend. Before leaving her home, Ichika slipped a small, amorous box she'd bought at the convenience store earlier that day into her pocket. Prior to going to Kiyotaka's room, Ichika first pay a visit to the Keyaki mall, buying whatever food ingredients she can find and add it into her shopping cart. Along with that, it was revealed in the volume itself that she in fact did bought condoms for Kiyotaka and Kei to use as well. Particularly, she picked up specific vegetables, fresh meat products, things that spoiled easily in general and went off to pay them with her private points. With that task over, she quickly head back towards the second-year dormitory and visit Kiyotaka's room, pondering if he will think of her as cute. Luckily, it was at the time when Nomura Shuuji also returned, that she followed after him from behind and got past the auto U-lock made by Kiyotaka, moving to the emergency stairs and headed for room 401 where both he and Kei were.

At the same time, Ichika tried to calm her heartbeat until she finally reached the door of Kiyotaka's room. Considering that there is a peephole for Kiyotaka to see through at the door, she intentionally hid the bag with the fresh ingredients in a dead corner from his sight. With all the preparations done, she rang the door chime and announce her visit to Kiyotaka without prior notice by the latter. After a brief lingering silence, Ichika felt Kiyotaka's presence across the door looking at her cute appearance to show off to him. However, she knows appearance alone is not enough to tempt Kiyotaka and wants to make him get to better know her even more. To that end, she plans to find a way to make Kiyotaka open up his heart and invite her into his room using whatever means possible. Ichika predict all the ways that Kiyotaka will try to reject her and turn the former away each and every time, knowing it will be fine regardless of the results as she plans to drag out her fight with him throughout the long-term. To Ichika, no matter how many cupid arrows she fire at Kiyotaka, Ichika believes that someday he will lose the means to fight back against her persistent action for him. In order to become close to a strong opponent like Kiyotaka, she understood it was necessary to thoroughly pierce and aim at his few weaknesses first. With that in mind, she proceeded to go forward and greet Kiyotaka, calling out to him in a sweet tone of voice. As she saw the door slowly being opened by Kiyotaka, she made a wide grin on her face by smiling towards his direction while eagerly looking forward to see his reaction to her showing up unnoticed.

Unbeknownst to Ichika, the fact that she reveal her being there at his doorstep ringing the doorbell had put a stop to Kiyotaka from almost going through with kissing Kei in the lips. After verifying that it was her who happened to be present to greet him, she was then met by Kiyotaka while the former explain to the latter of how she got to his floor without problem despite the lock. Ichika reasons that one of his fellow upperclassmen was returning to the second-year dorm and she ends up tailing the person back to Kiyotaka's floor in order to reach where he was at, hoping to surprise him with her visit. She express this visit by the former was done so out of her concern for him about his injured hand, hinting her role in the matter with Kazuomi Hōsen. While keeping her devilish smile, Ichika also confirmed that there were shoes put at the entrance besides his own, acknowledging Kei is there with him. She touched the U-lock softly with her right index finger and politely asked him to unlock it for her so she can get into his room. However, Kiyotaka refuses her invitation telling Ichika to leave him alone as it was already late in the evening and wants to delay their talk until the next day. In spite of Kiyotaka's reasoning that it's problematic having a kouhai like herself around at this hour, she shows no intention of leaving and asked him to cook for her while falsely claiming he seems to be the only person in the room. In order to find a way to get into Kiyotaka's room, Amasawa suddenly changed the subject and declares she has the right reminding him to not forget the help she offer him when nobody but her chose to be Ken Sudō's partner. He attempts to make her go away stating that he doesn't have any more food ingredients in the fridge to cook her a proper meal. Instead of feeling deterred, she felt a little amused by his reason and tells him that he needs to have reserves prepared just in case he doesn't have any which she does with her own bag of grocery ready. Ichika showed an expression that was troubled and not troubled at the same time, voicing her dissatisfaction.

Though Kiyotaka tries to sway her to go together with just the two of them to buy ingredients, Ichika states while it was bad he had no ingredients for her, she reasons there was no need for him to suggest that and tells him not to close the door. To destroy his escape route, Ichika disappeared from his vision for a split second and quickly reappear with a plastic bag full of ingredients she placed on the hallway floor, holding them up in her left hand so that he could see through the gap of the door. She sharply understood that Kiyotaka was lying to her from the start, thinking that perhaps he did not want her to come into the room was because he wasn't alone at the moment and still had his girlfriend with him. Ichika corners Kiyotaka further by honestly pointing out the fact that she has been watching Kei's movement all the time since she came back to the second-year dormitories and when his girlfriend enter his room. Braving the risk of the lobby's automatic lock locking her out twice, she made such a strategy silently and secretly without getting caught. She calls him out for hiding his girlfriend's shoes and inquires whether he was intimately committing lewd things with her before she arrived. When Kiyotaka discloses the truth, she realizes he has given up on trying to deceive her regarding how he and Kei are secretly dating each other. Ichika admits she can understand his feelings of why he wants to hide it from the public but felt there was a need to remind him that it was useless lying to her about his relationship with Kei. As if expressing her displeasure at being hidden from the matter, Ichika showed a disagreeable expression. While she had been keeping Kiyotaka's relationship with his girlfriend a secret out of good will, she threatens him on whether or not to reveal it if he doesn't let her in as material for negotiation. Even the fact that they weren't publicly dating seemed to have been investigated by Ichika. Realizing that his reason of having no ingredients himself was render pointless and that his relationship with Kei may be exposed against their volition, he finally decided to unlock the U-lock to the door of his room and allowed Ichika entry as she wanted.

After stepping foot into Kiyotaka's room, she came across Kei within her vicinity and smiled widely at her with a devilish grin. Ichika teasingly told the two that this isn't good when she found a young couple like them had been discovered alone by her in a room where the door was locked. Ichika who was filled with vibrant energy said that as she took her shoes off. Although she understands why Kiyotaka don't want to appear in the public openly with Kei, Ichika can't help but sense and feel something lewd happening between the two privately when the former wasn't around by looking at them together. As soon as she entered Kiyotaka's living room area, Ichika direct her sight on his bed while examining if there was any actual evidence of him having commit sexual acts with Kei lovingly. Seeing that there was none to take notice of except for the fact Kiyotaka's bed was tidy and that his clothes aren't messy, she came to the conclusion that they haven't had done the deed yet. Hearing enough of Ichika's remarks, she was loudly yelled at by Kei about what purpose was the former came to her boyfriend's room. Ignoring Kei's anger and questioning, Ichika replies back with admitting her honest thought how she guess that they should have already went through with an impure, illicit sexual relationship for sure like where the two have sex in secret. Although it was a lewd conversation, Ichika still took it a step further, pursuing the topic regardless but aimed her comments at Kei instead of Kiyotaka which he noticed. According to Kiyotaka, it was like Ichika was probing the couple's situation all along, and whenever she checked, she would look at the reaction on Kei's face. Upon understanding that she couldn't dig up any useful information from Kiyotaka, Ichika started to gather the details from Kei instead. Kiyotaka tries to intervene by saying the act of sex is forbidden by the school rules, Ichika shows no intention of backing down from the topic and continues with the conversation in rebuttal to his words.

As a matter of fact, she reasons to Kiyotaka that the school rules are just for decoration and that the two can violate it and each other without problem. Ichika backed up her claim stating how there were a lot of other couples that are doing lovey-dovey things openly in the school no matter what the rules say. Ichika even remarks how going to a convenience store to buy contraceptives isn't a school issue, comparing it back to her own past experience with trying to buy them before while the employee pretended not to see or care what she does. However, she understood Kiyotaka's worry and believes the real problem is him accidentally making Kei become pregnant through unprotected sex with her, reasoning how the school forbidding such lewd action may one day backfire and turn a guy berserk and impregnate a girl. After saying her part concerning the issue of pregnancy, Ichika used her left hand to take the contraceptive device out from the plastic bag as proof that she purchased it and placed the condoms onto the table for Kiyotaka to use in mating with Kei. She offer these things to Kiyotaka as a gift of apology, telling him that there was no need to play dumb and pretend she had no role in the matter with teaming up with Hōsen and following her accomplice's strategy where his hand got wounded in the process. Based on what Ichika had told him regarding Kiyotaka's injured hand and Kei's shocked reaction to hearing of that news, Ichika could tell from this statement by her how much he told his girlfriend, and whether or not she was someone worth talking to. To clear up the misunderstanding of what Kiyotaka might view her as and recognizing his hostility, Ichika supposedly claims that she herself is not his enemy. Though Kiyotaka refuses to believe a word she says, Ichika states whether this reason for him seeing her that way was just because she happened to shared her knowledge and planning out to Hōsen from the sidelines.

Ichika tries to deduce what Kiyotaka was thinking about her, stating that she must've played a part in Hōsen's plan to get him expelled, which raised the possibility of his expulsion. She figures that Kiyotaka was unable to hold the slightest trust in her, believing he might find her words ridiculous to take at face value after declaring how someone such as her was not an enemy to him. Ichika states that she has been underestimated by Kiyotaka but the latter thought otherwise saying it was his own full evaluation of her as he never once considered underestimating the former to begin with. She doesn't think the same of Kiyotaka's statement either and look back at Kei's panic reaction to her words, smiling meaningfully and revealing her keen interest of how much his girlfriend knows about what was going on behind the scene with him. Ichika then proceeds to mention to Kei in front of Kiyotaka about how there is a 20 million point bounty on him to intentionally start off the conversation between the three, using it as an opportunity to explore the relationship he had with his girlfriend. When Kei demands an answer what she meant by that, Ichika eggs the girl to ask her boyfriend about the details later. However, Ichika does honestly admit that she and Hōsen and wanted to use that knife her boyfriend bought to get him expelled from school in the Partner Exam and the reason behind why Kiyotaka noticed this was because he went shopping with her at the time. Ichika elaborates that it was her first time she saw the kitchen tools at school and how the former didn't hesitate in picking it out, admitting to Kiyotaka that she knew he would checked with the store clerk and and learned that someone similar like Hōsen wanted to buy the same knife as he was. Intentionally leaving behind this trace for him to pick up on noticing as she desired, Ichika concluded that's why Kiyotaka was able to immediately judged how he could defend against Hōsen's self-destructive actions.

In other words, the reason Kiyotaka could have known what to do next to counter Hōsen's strategy was because Ichika left a trace for him to find out later when he finally took notice of her action in the store before going shopping with him. It was a trace that hadn't been deliberately erased by Ichika which allowed Kiyotaka to understand what the right answer was, so that he could successfully defend against Hōsen's plan in advance. Kiyotaka acknowledge it's true that if Amasawa had acted perfectly with attempting to expel him from the start, the situation between himself and Hōsen might have change and the outcome may likely turn out different. After being called considerate by Kiyotaka, Ichika express how when suddenly her upperclassman got a bounty for his head, she thought that it will be a pity to not do anything about it if he ends up getting expelled without even grasping the full situation. At this moment in time, Kiyotaka thought she was probably the White Room Enforcer trying to reveal her identity to him indiscreetly without needing to spill the beans, and his level of vigilance towards Ichika had increased in his mind. Feeling tired of talking, Ichika states her mouth was running a little dry and request Kiyotaka that she would like some cup of coffee or any drink that he has available which he left it to Kei to handle that task much to his girlfriend's reluctance who accepted. Before letting Kei go to the kitchen and prepare her drink, Ichika reminds Kiyotaka's girlfriend to make sure to add sugar and milk to it as well, leaving the girl no other choice but to obey her order while throwing a small tantrum. At the same time, Ichika happily and laughingly teases Kiyotaka's girlfriend to not even think of adding garbage or sewage into her coffee just because Kei dislikes her. With she and Kiyotaka alone in the living room, Ichika looked towards the textbooks and the notebooks on the table and points out how very out of place the couple's study supplies are before her, considering how likely it was for he and Kei to have been up to naughty things while she wasn't around to see it.

While waiting for Kei to prepare her coffee, Ichika began to take a look over Kiyotaka's history book and test her knowledge with that study material. After reading the question, Ichika, holding a mechanical pencil in her left hand, wrote the words "World Heritage Convention" in Kei's blank notebook with pretty handwriting. Ichika then applauded herself for the correct answer she wrote which caught the attention of Kei who proceeded to loudly warn the former to not even think of writing on the latter's notebook without her permission beforehand. Contrary to her warning, Ichika refuses to comply to Kiyotaka's girlfriend and states that it should be okay for her to write a little bit on Kei's notebook. She went up to Kiyotaka's ear, whispering how his girlfriend has the known habit of being angry with her all the times throughout their interactions. Once Kei brought back coffee with the milk and sugar mixed into the cup, Ichika thanked Kiyotaka's girlfriend for her hard-work in preparing it. However, after expressing her gratitude, instead of drinking the cup of coffee as she requested, Ichika stood up to leave Kiyotaka's room. Ichika states that her purpose for coming to his room is completed as she have already given him her condolence gift as planned, reasoning it was time for her to head back while reminding Kiyotaka to please feel free to utilize the ingredients she brought to the guy. Ichika, who had finished saying what she desired, turned her back on the couple and prepared to leave the two alone by themselves. Kei demands an explanation from Ichika but she reasons it won't be good for Kiyotaka's girlfriend to have her time be ruin any further by her presence, admitting that she doesn't mind staying with them for a little while longer. Hearing her kouhai's response, Kei asked Ichika to go ahead and take her leave which she agreed thinking that was what Kiyotaka's girlfriend wanted all along. Ichika made Kei troublesomely prepare the cup of coffee on purpose to tease her before quickly making her exit out the door.

Later on the next day, after school, Ichika gone to the cafe at Keyaki mall to have a meeting with Kazuomi Hōsen of Class 1-D. Looking over Hōsen's watch, she voices her dislike and displeasure hearing the annoying tick tock sound it makes to which the man told her to shut her mouth as Ichika has no idea how much it cost him with his private points. Ichika shrugs off his rude remark towards her, saying how someone like her doesn't have the time to care for things she hate and was called a boring girl by Hōsen for that statement. Ichika was about to counter his words but shortly stop caring as she proceeds to question him for calling her to this meeting with him and Tsubasa. Ichika learns from Hōsen that he asked her out to team up with him again but for the Uninhabited Island Exam. Seeing that he is asking for her help twice, Icihka teases Hōsen that he is trying to do something vulgar with her. Even as Hōsen frowned and stared at Ichika in the eyes, she fearlessly returned his gaze with a devilish smile. She slowly lowered her crossed legs, then quietly opened them up for him to take a small peek at, inquiring if he wants to inspect her panties closer beneath the table. She knows Hōsen was the type of guy who was willing to get his hands dirty by laying a nasty finger on her, reckoning he would go so far to beat any girl up and act as if nothing had ever happened. Hōsen told her that if she knew this much, Ichika was told by him to quit playing around and seriously take his deal into consideration. Understanding that her tease was a waste of time for Hōsen, she decided to accept hearing him out and his new plan to tackle the upcoming exam while asking why he had invited her in the first place. Hōsen explains the reason for his invitation was since Ichika happened to be a bold girl who didn't hesitated on trying to expel Kiyotaka. She admits her boldness and felt the same cannot be said with the other first-years who she guesses that they either knew the bounty and didn't do anything or wanted to do something but gave up on the objective halfway.

More so, she felt it was odd why they are not going all out in expelling Kiyotaka when the bounty was said to be worth 20 million private points. Ichika said that without showing any signs of guilt. However, Ichika came out and bluntly states that her service to Hōsen was not cheap and that she needs to be rewarded with something in return for teaming up with him. Before long, Tsubasa Nanase arrives late and tells Ichika that they were supposed to be on equal footing. Ichika finds the girl's words as bitter despite praising the latter for having a cute face, wondering if this so-called boldness Hōsen was referring to the former earlier applies the exact way for Tsubasa as well. Seeing how she was the last person to arrive in this meeting, Ichika understood the group that Hōsen was thinking of forming was the three of them and questioningly asked if there will be a fourth member in the team. He tells she and Tsubasa that there was no need to recruit another member besides just the three of them, proclaiming to Ichika how only they will be the ones to emerge victorious in the Uninhabited Island Exam against the second-year and third-year students. She felt his overconfidence in their chances of winning the exam as cocky, reminding him how there are a very lot of formidable upperclassmen among the second-years and third-years compared to their fellow first-year students. She reasons with Hōsen that even if he was the strongest, she states it didn't change the fact that all four first-year classes agreed to work together in forming the most powerful group, recognizing him and Tsubasa to be part of Class 1-D's main fighting force. Hearing how likely it was for Hōsen to not have Class 1-D abide by the promise of cooperating with the other three classes, she understood he will openly send forth the small fries from Class 1-D to represent the main forces for the three classes to take in without either himself or Tsubasa tagging along. As Hōsen was looking to have himself, Tsubasa and her create a group together, she points out that his action will end up upsetting Classes 1-A, 1-B, and 1-C when they were expecting Class 1-D to fully cooperate with them.

Nonetheless, she was well aware that teamwork will be impossible if Hōsen choose to join hands with the three classes anyway, making sense to exclude him from that group as it was the safer option to go for. With that said, she had the two return to the main topic of the discussion, asking Hōsen about exactly how many private points will he offer he in exchange for her helping him to expel Kiyotaka. Tsubasa argues that Ichika can't get an unfair amount of private points as they're supposed to be on equal footings with each other where the rewards like the extras are evenly split between their sides. However, Ichika disagrees and explains that the reward won't align with her contributions. Whether it's the Uninhabited Island Exam or something else, Ichika expresses her confidence that she'll be able to contribute the most among the three of them. Since this sort of exam require quite a lot of physical strength to muster, Ichika teasingly and provocatively questions Tsubasa if the latter could actually keep up with her abilities despite how cute and lovely she looks in her eyes. When Tsubasa responded aggressively to her provocations that she wants to put their strengths to the test, Ichika turned her attention away to Hōsen for a moment. Right then and there, without warning, Ichika stretched her hand out suddenly to Tsubasa's face and wanted to slap her in order to rattle her but the latter block the former's attack, grabbing her arm that was quickly extended at the same time. Seeing Tsubasa's strong resistance to her attack, Ichika admires the girl's guts for trying to challenge her in a battle of physical strength and begins further testing her out. After some time passes by, Ichika was suggested by Hōsen to join him and Tsubasa in a group as she should understand the girl's strength by now.

Although she now know that Tsubasa has considerable skills in her own right, Ichika however still can't help but think that neither the two of them are on equal footing with each other, implying that she herself was still better than her. Yet Tsubasa claims Ichika must've reach such false conclusion due to her being in Class 1-A while she is in Class 1-D. However, Ichika refute her words stating that she could care less about the difference in their class position but felt concern about their end of the bargain. While Ichika accepts the condition that the private points will be evenly spit, she argues that because the two are the ones asking for her help, the former demands extras more than proposed by them. After Ichika said that, she made a fist with her left hand, then made the gesture of asking for a tip: pinching her thumb and index finger together and then rubbing them. She felt it was a natural thing to selfishly demand by increasing her price of lending a hand since they're trying so hard to bribe her into conspiring with the two. She reminds Hōsen that nowadays, girls are the stronger ones than the boys. Now that Hōsen is willing to hear her out, Ichika states her conditions as follow whereby they must reach 1st place in the Uninhabited Island Exam and she had to be the one to receive all the private points from the bounty to expel Kiyotaka. She changed the position of her left hand, and raised only her thumb to her neck then, slowly slid it from right to left to emphasize her demands.

Through that gesture, Ichika arguably explains that Hōsen can't do anything right without her help as he has made enemies on all sides of the spectrum and the only ally he can count on trusting was just Tsubasa, reasoning he will have a difficult time overcoming this exam if she doesn't take part in their strategy. Ichika backed up her argument even further saying that if the former were to group up with the likes of Hōsen, she'll be even more ostracized and isolated in Class 1-A than where she was now. Ichika states it was only natural for her to ask this much in return for teaming up with them and not say ‘yes’ to their proposal immediately if she don't get the corresponding rewards that would compensate for that loss. While gazing at the man, she reasons with Hōsen that though he won't obtain any money from expelling Kiyotaka whatsoever as she is going to be taking the bounty for herself, he will be able to gain the reputation for being the person to have cause his target's expulsion to happen. Ichika states such a condition should be more than enough for Hōsen to accept which he gives up in resisting and agreed to her demands. Seeing that the bounty is now hers for the taking, she convey her thanks to him and the fact that he was not a stingy guy is simply brilliant to Ichika. After saying that she will be in their care during the exam, Ichika briskly stood up from her seat and left now that the negotiations was finally over. As a result of this meeting, she decides to team up with Tsubasa and Hōsen to form a group to expel Kiyotaka from the next Deserted Island Special Exam.

2nd Year Volume 3
Once the Uninhabited Island Exam begins, Ichika decide to split off from her group members, Kazuomi Hōsen and Tsubasa Nanase and scout out the area. By entrusting Ichika and Hōsen with arriving in time at the designated areas and doing the tasks, Tsubasa wouldn't be penalized for missing them as long as they've reach there before her. While the team wouldn't be able to get any Early Bird Bonuses as they are not together in an area to do a task, Ichika and her group members could still steadily pile up points, two points at a time. In a way, both Ichika and Hōsen felt that their group would be better off if they all acted independently from each other. Between Ichika and Hōsen, they've been earning quite a few points from going to designated areas and completing tasks recently. Although she was not completely sure which one of the two has been contributing the most in the team, Tsubasa does recognize that both Ichika and Hōsen appear at least to be doing more work than her when it comes to earning points for their group individually.

Journeying alone in the island, she silently met and caught wind of Kikyō Kushida for the first time who was trying to use her tablet to record the fight between Kiyotaka and Tsubasa in order to get him expelled while spying on the two. Ichika firmly place one of her own hands on Kushida's shoulder to stop the latter from moving closer to their location and uses her other hand to immediately reached to cover up her senpai's mouth from making noises that will expose them to Kiyotaka and Tsubasa. Ichika got up close to Kushida's ear and faintly whisper to her senpai, saying that while the latter may be surprised by her sudden appearance, the former tells the girl to remain quiet and hidden as it will be bad if they're discovered. To avoid getting caught on by Kiyotaka and Tsubasa, Ichika effectively dragged Kushida farther away from where Kiyotaka and Tsubasa were at until she finally lets her go once they are out of sight. When questioned by Kushida of why she was with her, Ichika explains that she herself just so happened to be passing through the area nearby when she saw her senpai acting all sneaky-sneaky towards Kiyotaka and Tsubasa. In spite of Kushida denying that is the case, Ichika harbors her doubt whether what she said was true, approaching closer to her senpai with a somewhat suspicious look in her eyes. After she got close enough to Kushida, Ichika suddenly smack the girl's face with a hard slap on her right cheek. At this moment in time, Ichika interrogates Kushida, stating how she came poking her nose around in the mountains all on her own and inquires what her senpai was really trying to get at by telling the former such a lie. Seeing that Kushida continues to play dumb and maintain her fake persona, Ichika states she is excited to see how long her senpai can keep up with hiding behind that mask of hers and has no intention of stopping despite the girl feigning a sense of terror and fear. With that said, Ichika drew closer once again and plans to torment her further while raising an open palm up in the air.

Kushida tried to cower back and protect herself, but Ichika forced her way past her senpai's defenses nonetheless. As a result, she physically hurts Kikyō with another hard slap again except on the left cheek instead, causing her senpai to reel in pain. Ichika tells Kushida this was her own way of being pretty gentle with her without badly hurting the latter too much. While Kushida said such violence makes no sense, Ichika noticing that the girl was still not understanding her situation decided to push further with violence once more. Trying to get her senpai to connect the dots of why she is doing this to her, Ichika smacks Kushida harder with her fist rather than by a slap this time to the point that the girl was push back and fall down to the ground. Upon making the girl's face bleed and hurting her a little painfully, she tells how rare it must have been for Kushida to experience getting beaten up in this state. Looking to aim another hit on her senpai's cheek, she started approaching her all over again while Kushida attempts to resist by pushing Ichika's arm away to avoid her outstretch hand. As Kushida continues to pretentiously act like the goody two shoes, Ichika reveals she already knows her senpai real well, calling the girl out as a nasty, vile woman who egotistically thinks she can convince anyone with that cute face of hers in the open. Right then and there, Ichika exposes Kushida's desire of wanting to feast off other people's deepest darkest secrets and how if the latter were to ever get into troubled with it publicly, she will gladly self-destruct just to drag everyone else down along with her. When Kushida attempts to feign ignorance of not understanding what she said and belittle the kouhai for inciting violence, Ichika dares her to go and cry to school about it as she herself doesn't care of getting expelled for her own action. However, Ichika states that if Kushida were to went ahead and do it, the former declares she will also leave behind a parting gift whereby exposing all of the dark, dirty middle school secrets the latter have been trying so hard to keep hidden and take away her status.

After Kushida questions her of how she knows about that, Ichika guesses how her senpai may be thinking that she must of heard everything from Kiyotaka Ayanokōji, keenly reading the expression on her face. She said her guess is wrong as Ichika tells Kushida that nothing in the world gets past her while calling herself a special existence. Ichika breaks Kushida's resistance further through revealing that she knows about her senpai's past action in high school like when she tried to cozy up to Student Council President Miyabi Nagumo, but got turned away at the door. Ichika told Kushida that even if the situation with Nagumo ended up working out for her successfully, she cast her doubt it won't be enough for the Student Council President to support her since Suzune Horikita who is from the same class as the latter joined his group. Seeing Kushida's shock, Ichika devilishly smiled down at her as if she was just some toy for her to be play with. Realizing Ichika exposed her for the faker that she was and reaching the limit of her patience, Kushida finally become madly frustrated and show her true personality in rage. While she was delighted to see her senpai's true colors, Ichika warns Kushida to calm down and keep her anger under control, reminding her to shush up as there's no telling when someone else might show up because of the noise the latter was making. Particularly, Ichika reprimands Kushida that just because the island is vastly big and nobody is around to see the two of them bickering doesn't mean it was impossible for them to be discovered. Ichika crouched down and playfully tapped Kushida on the nose, giving her senpai a gentle, patronizing warning which upset the latter even more so. Unable to control herself any longer by Ichika's disgusting attitude towards her, Kushida refuses to care anymore and curses her kouhai anyway. Ichika cannot help but let out a giddy laugh in response to the girl's honest personality, laughing herself off and saying that the attitude Kushida is showing the former now suits her far better than that mask she puts on.

When Kushida demands what the hell she was, Ichika felt somewhat unsure of how to answer that question but tells her senpai that she came to this area in order to save Kiyotaka. She tells Kushida there was no point in hiding her objective any longer, stating how the latter was planning on finding some dirt on Kiyotaka with that tablet she dropped over there to try and get him expelled through recording his fight with Tsubasa. Ichika intimidates Kushida, telling her senpai that she can see her every move like an open book. She mocks Kushida for her naivety of not understanding Kiyotaka whatsoever and underestimating him despite them being in the same class together for over a year. Ichika told Kushida that there was no way someone like Kiyotaka would feel threatened by her shallow display of thinking. Ichika turned her gaze toward where Kiyotaka and Tsubasa are at, expressing her desire to sit back and watch from a frontrow seat as the fight between the two play out. Ichika more or less understood that Kiyotaka could successfully defeat Tsubasa without even injuring her which she wanted to really see happen but can't due to her attention focus on Kushida at the moment. After mumbling a few words to herself, Ichika turned back to face her again and states that she has no idea who would put Kushida up to this task of recording Kiyotaka and Tsubasa fight but felt that the girl was letting herself get used. Ichika informs Kushida that no matter what things are like over there between Kiyotaka and Tsubasa, nothing would work out as the latter planned, arguing how Kiyotaka has already taken notice of what she had been up to behind his back. She criticizes Kushida's ability to conceal herself from Kiyotaka as amateurish to the point where Kiyotaka would easily sensed it. Because Kushida disagreeably argue back that she was putting plenty of distance between herself and Kiyotaka, Ichika points out the fact that her senpai accidentally admit to her that she was stalking him all this time.

Kushida tries to explain the reason for her action, but Ichika doubt that was the case as she keenly sound out her senpai's excuses thinking it was not a coincidence the girl was tailing behind Kiyotaka and Tsubasa out of curiosity by heading up this rough mountain trail all on her own. When she was told by Kushida that it was none of her business, Ichika intuitively understanding her senpai's uncooperative attitude rebutted the latter's argument that it does in fact actually has quite a lot to do with her, proclaiming how Kiyotaka is a very special person to her. Kushida believing her kouhai likes Kiyotaka romantically was refuted by Ichika who told her senpai to not come to such a vulgar conclusion as her feelings toward Kiyotaka was very much far beyond the concepts of both "like" and "love" altogether. After having gone out of her way to tell a lot including the meaning of her own feelings properly, Ichika advised Kushida that she needs to head down the mountain and go back to her group like a good girl. Ichika states that this will be Kushida's last chance of turning back and asked her to give up on her objective, reasoning the weather's gonna turn bad any time now if she doesn't leave the area soon. Kushida furiously voices her refusal, taking a clump of wet soil in hand on the ground and threw it at Ichika as a means of rejection. Listening to her protest, Ichika reminds Kushida that even if she get Kiyotaka expelled, the kouhai states how that result was not going to solve anything about her problems. Ichika reaffirmed her own commitment to protecting Kiyotaka from outsiders such as Kushida who're trying to expel him, vowing to never allow her special person to face expulsion by them.

Ichika reached out and mercilessly grabbed hold of Kushida's bangs, wrenching up her senpai's head to draw her eyes level with her own. Kushida demands to be let go, but Ichika refuses and ponder why she would do something like that. To Kushida, Ichika's colorful eyes seemed like hollow, empty voids. She felt Ichika's eyes were ones that had lost touch with reality. When Kushida calls Ichika a freak and not normal, she grew curious of seeing the girl shaking in fear by a kouhai who was younger than her, suggesting her senpai that it would be best to cherish such wonderful feeling from now on. Ichika remarks how Kushida thinks she is the cutest, smartest, and better person than everyone in the school. Ichika mocks Kushida as being hopelessly in love with herself to the point that her mouth waters at the thought of asserting her dominance against anybody, always yearning to learn and take a hold of other people's secrets. At the same time, Ichika points out to Kushida that was why the latter hates the mere thought of losing control of such power the former crave, forever unable to forgive those that know her secrets, history, and true personality. In spite of what she said about her, Ichika admits she doesn't really mind at all her messed-up attitude. When Kushida finally regain her composure and stood back up, Ichika compliments her senpai for being able to quite amazingly made it out this far to where Kiyotaka and Tsubasa was at on her own without getting caught until now by her. Ichika guesses Kushida must've not only got her tablet but also someone helping her as well, but acknowledge it doesn't change the fact that she has the strength to walk a long distance with her own two legs. Ichika figures she also must've had quite a difficult time confidently deceiving her fellow group members to get past them before going after Kiyotaka and Tsubasa. Let alone this, Ichika reasons that Kushida breaking away from her group carries quite a bit of risk too as it toe the line of expulsion more and more by cutting back on the points she earn. After saying that, Ichika knocked Kushida off her feet again and proceeded to look down on her from above once more.

Ichika understood Kushida has a way to escape expulsion in this exam, disclosing in the open that her senpai wouldn't overlook her reckless movement without taking into consideration the consequences first. Ichika reveals that even if Kushida's actions put her group's position at risk where they sank to the bottom of the leaderboard ranking, the former presumes the latter must have at least readily saved up the private points needed to ensure her own survival beforehand. Though the girl protest in resistance, Ichika inquires how Kushida plans to escape her grasp, doubting that she can easily run away when her senpai is in the palm of her hands. Seeing how determined Kushida was being, Ichika accepts that this strong resolve was far more than she herself can imagined coming from her senpai, cursing her as a nasty individual. Nevertheless, Ichika was not without admiration for Kushida, praising her senpai for her mental strength to go on fighting to the very end as very praiseworthy. Ichika recognizes that Kushida's strength was not from fear but by the overflowing hatred which gives the latter a reason to resist the former, understanding it was not only directed at her alone, but also at anyone who happened to discover the truth about her past. Ichika tells Kushida not to bother opposing her as the latter won't stand a chance against the former even if she had her hands tied fighting the girl. When she proceeded to turn her back away from Kushida and prepares to leave, the latter attempts to throw herself at Ichika, knock the kouhai off her feet, and pinned her down onto the ground. However, Ichika had seemingly predicted that Kushida would pull this sort of maneuver as the former effortlessly sidestepped the latter's strike just in the nick of time, leaving her senpai to come crashing down against the ground instead.

Abilities
In contrast to her appearance, Ichika has high physical abilities and academic abilities having an A in both of those categories on OAA. She is also known to be intelligent and cunning, which is acknowledged by Kiyotaka himself to be comparable to Arisu Sakayanagi. She was able to keenly see through whatever strategy Kikyō Kushida was scheming to do whereby recording the battle Kiyotaka had with Tsubasa Nanase as evidence to get him expelled. Ichika would go so far as to use violence on Kushida to force the latter in not only revealing her true personality to the former but also giving up on the plan as well. As a girl who was once raised in the White Room for years while being part of the 5th generation, Ichika happened to developed very high-level interpersonal communication and collaboration skills unlike Kiyotaka. It was easy for Ichika to adopt the attitude of a high schooler and adapt to the school's environment better than Kiyotaka did. She could skillfully and deceitfully pull off an rich assortment of different facial expressions to show how talented she was with her acting abilities. Kiyotaka regarded Ichika's physical strength to exceed even that of Ken Sudō and Kakeru Ryūen, believing neither of the two could stand a chance in winning a fight against her due to the variety of refined techniques she was trained in to overwhelm them. This was indicated when Ichika was able to easily toy with and one-sidedly handle both Suzune Horikita and Mio Ibuki all on her own without problem while having already sustain a heavy physical injury to her body prior to the match against the two. She was able to dish out a painful blow to her targets like Kushida without the latter quickly reacting to that incoming attack on time until it was too late to do so upon realizing that they've been hit.
