Kokushibo is 6'2 with black hair and red tips, he has 6 eyes, the scelcia being red while his irises are yellow. He has pale skin and 2 of his eyes show that he is the uppermoon 1 demon, Muzan's right hand demon and most trusted 'business partner'... Although, something is different. The rumors failed to say that Kokushibo had cat ears and a cat tail, and most likely some animalistic habits... He is cold toward most people, and has a short temper. He is known to like being dominant.
