Head of the Kyuso Clan and self-proclaimed "emperor of the night". He is an anthropomorphic rat yokai who first appears as a light-haired playboy going by the name Seiya. He runs a host club near the east entrance of Ukiyoe Town's shopping district. He is a cruel and cold-hearted rat who takes advantage of people's weaknesses. He is able to summon regular-sized rats to do his bidding, and seems to hate rejection.
