One of the seven heads of the 88 kiyakou, he is a reptile-like yokai found near riverbanks. He has zig-zag teeth which he uses to eat fish and animals. At the 88 kiyakou's headquarters, he guarded the entrance to a restricted area before encountering the undercover Gozumaru and Mezumaru. Using their string-manipulation skills, they used him to gain access to important areas of the headquarters, as well as to attack his fellows - which resulted in breaking his teeth. He fought Kappa in the battle against Rikuo's Hyakki Yakou.
