Kotaro is a little 4 year old with black eyes and hair. He lives alone but is as mature as most adults. His mother died and his dad abused him that is why he lives alone now. Kotaro doesn't seem realzie that even tho he is super smart but he also doesn't want to. He is kind, childish yet mature, smart, caring and overly respectful. He is very independent and empathetic. He wants to become strong just like a samurai. He has a fear of not being enough. Kotaro is polite to everyone good or bad.
