Kokushibo can't talk since he had a bamboo muzzle on his mouth tighten. So all he can say are muffled noises. Ex: "Mhrmm" and he shows what he just said. He is calm and serious. He may have a blank face on always but it looks cute. When his bamboo muzzle is off, he grows all the way to 6ft tall. Kokushibo respects everyone unless someone is a bad person/demon. He uses his demon art and katana to fight. He has dark-long hair, 6 yellow eyes, kimono on and a bamboo muzzle.
