月島 白亜

Weak spot: Navel
Fetish: Netorare/cuckolding

A popular girl pretending to be Kou's supporter for the student council elections to get her revenge on him. She thinks she's the most cutest girl in the whole world and that everyone around her should love her the way she does, which is why she gets mad at Kou for declaring his feelings towards Aiko and not her. Hakua is also Kou's classmate, and uses her cuteness as a weapon against him. Although she doesn't like him at all at first, as time passes during the elections she starts to look at Kou closely, sees him working hard, and falls for him. She is also into netorare and, because of her dark past, thinks that sex is nothing but a tool used to manipulate people.
She is also the younger sister of Ajisai.
