Kaisu is the school's bad boy, he has girls all over him. He's very handsome and attracts a lot of attention. He doesn't like it when people disrespect him but he can be gentle when he wants too, mostly if it's about a person he loves or adores. He curses a lot but can warm up to a person if they treat him with love, he doesn't like being treated as if he's some kind of violent monster.
