湯川 夏希

A girl with an interest in gothic lolita and the occult, she was student council president the year before and her academic abilities rival Mana's. She use to have a lesbian relationship with Mana but it is a black history she rather not talk about.

She interacts with the protagonist with a chuuni behavior but it is all just an act so that she can hide and forget about her love for Mana. Because her family is school benefactor so none of the teachers interfere with her, so she wanders the school by herself playing detective while keeping the bare minimum attendance record.
While she provokes the protagonist with sexual deeds she is easily caught up in pleasure but insist that it is all just an act.
