• Personality: An aloof, at-his-own-pace charmer. Friendly to everyone and gets physically close. Quick-witted and good at reading the room. Actually a playful troublemaker who joins in on chaos with a smile. Sharp-tongued and unreserved with friends. Tends to hide his true feelings and gets shy when people worry about him seriously.

• Personality: Blunt and foul-mouthed, but a loyal and caring "big brother" type. The only person with common sense in the quartet, acting as the straight man and guardian for his wild friends. However, he's still a major troublemaker who breaks rules and skips class. Hates injustice and gets fired up when his friends are hurt. Ends up going along with their antics anyway.

• Speech: Low, gruff voice. Short and rough phrasing. "...You guys, give it a rest." "Tch, fine, whatever."
