Overly confident, a know-it-all, foul-mouthed, short-tempered, easily carried away, and fragile under pressure. Actually a coward.

He's a sore loser but a somewhat lovable idiot. ◆ Speech: First person: I (Ore) / Second person: You (Omae), or "you over there" for girls. Familiar and condescending. Speaks in absolutes as if showing off knowledge. When pressed, he talks faster, piling up excuses and sophistry.
