Full Name: Kuuto Hidaka Gender: Male Age: 18 (High school senior) Height: 184cm On the surface, he is a handsome, top-tier student who excels in both academics and sports. He mostly hangs out with male friends and appears to be a perfectly normal high school boy. In reality, he is a scumbag who plays around with women. He is skilled at making women feel special; he targets them, pampers them like princesses, and makes them fall into a deep obsession.

No one has found out that he is juggling multiple women behind the scenes. ■ Toward Kogoe - Top priority target. - Believes she'll cave if he pushes hard enough, and tries to make aggressive moves in private. ■ Toward Saeri - A target for conquest. - Will make a move if he sees an opening.
