白石 葵

Aoi is the little sister of Tsubame and the cousin of Shuuji who's living together with them. She is a second year student and is the classmate of Shuuji, Kouichi, Itsuki and Shinobu. She is also a childhood friend of Amane. Seeing that her cousin was in a problematic situation, she has consulted with Tsubame and picked Shuuji up to live with them. She is very close to Konomi and her policy is "there's no need to work hard".

Aoi is a girl who has a double life, she is very lonely and reserved for school, dressing so as not to show off, wearing glasses, tying her hair, with the label of the serious and boring student, which means that she has no friends at school, even coldly avoiding her cousin when they meet in class. Outside, Aoi is another girl: she is a stylish and a famous model knowed as Shirai Sumire (白井 スミレ) with a shoulder-length bob and is very sexy. At home, Aoi is much more relaxed. Wearing revealing clothes as pajamas and playing retro games in the living room (his favorite game is Pokevy, a very long game that has no backup function). When Aoi learns that Shuuji is in a relationship with Itsuki, she picks him up in the living room and orders him to explain.

The relationship that Aoi and Shuuji maintain is similar to a relationship between siblings. They heckle, make derogatory remarks and tease each other all the time. However, Aoi loves Shuuji very much, like her brother, and this love is reciprocal. She is ready to do anything for him if he has problems. She has no embarrassment with Shuuji because she doesn't see him at all as a potential lover of the opposite sex, even asking him how he does to "endure" his impulses since he lives alone with two pretty girls. She even thinks that Shuuji fantasizes about Tsubame because he always looks "discreetly" the breasts, buttocks and thighs of her sister.

Aoi thinks a lot about the future, wondering what she'll do the day where her sister will leaves home or thinking about her futur marriage.

She believes that Shuuji is no longer a virgin since he was Amane's boyfriend for a while before separating. She is very surprised to learn the opposite, calling him a hetare or telling him he must be gay because he has been hanging out with Kouichi for over a year, playing video games in his room.

Young, Aoi was obese and was martyred by the boys at her school. She decided to go on a diet and she lost weight when she entered in middle school. At the same time, Aoi had three cups more than her classmates, attracting boys who once mocked her. She is currently wearing F cup and and is always sensitive to comments concerning her physique.

In her route, Shuuji accidentally enters the bathroom while she is there and he sees her wearing sexy underwear. Aoi kindly asks him to go out because she knows that he didn't go into the bathroom on purpose but she realizes that Shuuji is all red and that something unusual happens so she asks him to wait for her in the living room. Once in the living she asks him for explanations and Shuuji answers her honestly that he didn't know she was in the bathroom but when he saw her in her sexy underwear, he couldn't help but to see her as a magnificent woman. Aoi is very embarrassed because she knows that Shuuji has told what he really thinks so she doesn't know how to react. She then tells him that it's not that bad and they shouldn't think about it anymore. Except that the damage is already done and Aoi's feelings are starting to change./
