Satori is a Kyoto Yokai who works in tandem with Oni Hitokuchi and is one of Hagoromo Gitsune's loyal followers.

400 years ago, he and Oni Hitokuchi 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.
