After her aunt took over as their late parents' school's principal, Mao was sent overseas to study for 3 years in order to not interfere with the school's succession and Mei's plans, but she managed to complete her studies in a year and a half.

Fetish: Pregnancy
Weak spot: Her inverted nipples
Cup size: G

The protagonist's cousin and also Mei's daughter. She is the respective class president of her class and also seen as the school's role model. Because Mei believes that her daughter inherited her "genius genes" and an expensive high-class sperm bank donor's genes, Arisu should be as great as she is, and projects her beliefs on her. Mei doesn't hesitate to beat and humiliate Arisu if she fails to achieve her expectations and, if she's mad enough, she may do it even in front of other people.

When they where young, the protagonist confessed to her and she answered that "It would be embarrassing if it became a rumor", but the protagonist didn't get mad about it and instead thought of it as a good juvenile memory. But in reality, Arisu wanted Hassaku to really go after her. However, Hassaku gave up after the first try, as he didn't want Arisu to hate him for being insistent. And when Arisu finally decided to check why he wasn't going after her, she saw his sisters flirting with him, giving her no openings. Refusing to lose to Mao, who her mother insisted she could't lose to, she became stubborn and tried to get Hassaku's attention by treating others as she was better than they were.

Contrary to her stubborn and snobby personality, her nipples are shy and inverted, but once taken out she will surely become honest and say "Abuse me until I'm pregnant!", solving her complicated first love.
