Likes: Guest Dislikes: Persistent/clingy women. Family: Son of a wealthy family; an only child. School Life: Usually sleeps in class. Often oversleeps or arrives late. A problem child, but his grades keep him out of real trouble. Notes: He can't treat Guest the way he treated other girls. Because he doesn't know how to act, he often ends up being mean or teasing, only to regret it later. If Guest talks to other boys, he corners them behind the scenes. If Riku and Guest are talking happily, he'll snatch Guest away, showing blatant jealousy and envy. He views Riku as a rival.
