History
Not much is known about Ichika's history. 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.

Plot
In LN Year 2 Arc, Volume 1, after overhearing that they were looking for a good partner, Ichika approached Suzune Horikita, Kiyotaka Ayanokōji, and Ken Sudō in Keyaki Mall, offering to partner up with one of them for the Partner 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 under certain conditions that must be met first before going through with their partnership deal as she has the right to call the shots. Ichika states that she liked strong, powerful-looking 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. After showing that she was serious about her condition, and seeing Suzune and Kiyotaka's attitude towards Ken's strength, she changed her mind, stating that no one would probably show up to fight Ken. Ichika then changes her condition by saying that she liked a boy that could cook, which leads Suzune to lie that Kiyotaka had mentioned before that he could cook. Ichika says, as her new condition, that if Kiyotaka could satisfy her in terms of cooking, she wouldn't mind being partner with Ken in the special exam.

The next day, she met up with Kiyotaka at the Keyaki Mall and bought cooking utensils and ingredients for the meal. They headed towards Kiyotaka's room at the second year dormitory, which was neat and clean. Ichika relaxed inside while stating that she liked to eat Tom yam kung, which was a Thai dish. Kiyotaka prepared the dish and presented it to Ichika for a taste test and she seemed satisfied with it. Afterwards, she offered to clean the dishes since she was the one who had forced Kiyotaka to her cooking test, then she agreed to be Ken's partner for the Special Exam.

A few days later, she visited Kiyotaka's room, stating that she had lost her favorite hair rubber. She saw Kei Karuizawa in the room studying with him. Kei introduced herself, and asked her about her relationship with Kiyotaka, and she told her that Kiyotaka was her personal chef, and later teased Kiyotaka for looking at her butt while she searched for her hair rubber, making Kei annoyed. Then Kiyotaka said that he had cooked for Ichika before but could not tell her the details. After she found her hair rubber in the kitchen, she apologized for her teasing and left the room.

It was later revealed in that she had played a role in Kazuomi Hōsen's plan to expel Kiyotaka, but her motives remain unclear.

In LN Year 2 Arc, Volume 2, she decides to team up with Tsubasa Nanase and Kazuomi to form a group to expel Kiyotaka from the next Deserted Island Special Exam.

In LN Year 2 Arc, 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.
