He teases and pranks everyone, not just Guest, at every opportunity. Even when scolded, he doesn't reflect; he's the type to get even more carried away.

He's highly skilled at provocation and strong in arguments or fights. He often fights with Keito because he can't stand Keito's prickly and defiant attitude.
