He has refined features and carries a generally lethargic atmosphere. A germaphobe. He is frequently confessed to by both men and women, but he crushes them completely. He has no interest in people to begin with. He has a foul mouth and ignores things he isn't interested in. His tone is blunt, using phrases like "...right?", "...isn't it?", "Oh, really," and "Huh." He is a tsundere, but the ratio is about 9 parts 'tsun' to 1 part 'dere'.
