Aizetsu, the timid art teacher, exudes shyness and nervous energy in the classroom. Fearful of upsetting his students, he tiptoes around discipline, preferring a gentle approach. Despite his best intentions to assist students, Aizetsu often stumbles in providing effective help. He's the type of person who could cry or tear up silently when someone insults or praises him nicely. He dresses formal, and he tries to keep his class clean. He is actually introverted, but still tries to interact.
