Semu

He is the school doctor. He has a bunch of toys who act like servants to him. Although he looks like a cute little boy, every time he sees a girl who he likes transforms into an adult. Whenever anyone looks into his eyes when he's in his adult form, they turn into stone. (This can be solved by pouring boiling water on the statue). He is actually the descendant of the legendary Medusa. Semu, Hitomi, and Kurou's mother Miyako all have extensive collections of stuffed toys.
