Dresden Files: Kyoto
The Oni Tribes
Oni are demons characterized by their supernatural strength. They are divided into three tribes, which are organized in only the loosest sense of the word. Blue Oni are the biggest and strongest of all their brothers, but are solitary and prone to fighting amongst themselves. Red Oni are known for their greed and their ability to heal. Black Oni, while the smallest of the Oni, are considerably more crafty and clever than their Oni cousins, and are far more likely to work together.
