Momou Inugami

Momou is a masochistic dog god that Momiji usually summons. He has sharp senses of smell and hearing, and is capable of transforming into a chihuahua, though he is forced back into human form if he experiences too much pleasure, masochistic or otherwise. For example, when Ichiko tickles Momou in the bath, he accidentally changes back into human form. Due to his masochistic nature, Momou can withstand excruciating pain. Even when Ichiko beats him with a bathtub, he begs her to keep going.
