Previously a delinquent, Hachiyo now suffers from amnesia and is a good student. In actuality, she pretends to be a good student to be with her crush, Marui.
As a good student, Hachiyo acts as any normal student would. On the inside though, she has much different views compared to what she says. Hachiyo, as her true self, is loud and violent; yet she still has a soft spot for Marui.
