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. 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 is provocative with her 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. 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.

History
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. 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.

She decides to team up with Tsubasa Nanase and Hōsen to form a group to expel Kiyotaka from the next Deserted Island Special Exam.

2nd Year Volume 3
Ichika catches a spying Kikyō, who tried to use her tablet to record the fight between Kiyotaka and Tsubasa in order to get him expelled. Tormenting her, Ichika physically hurts Kikyō, causing her to show some of her true personality. Ichika goes on to explain that such a sloppy act would not even affect Kiyotaka, who had already noticed the presence of a third party. Kikyō then angrily questions her relationship with Kiyotaka, asking if she liked him, to which Ichika replies that it was something that transcended love.

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.
