Oni Hitokuchi is a Kyoto Youkai who works in tandem with Satori and is one of Hagoromo Gitsune's loyal followers. 400 years ago, he and Satori gathered princesses with abilities for Hagoromo Gitsune to eat. They used the ploy of making the princesses concubines of Hideyori Toyotomi to buy them away from their families. When they visited Youhime's father and he had greedy thoughts, Oni Hitokuchi beat him to death.
