The oni (鬼) are a race unique to the Afterlife. All are humanoid in appearance: most have blue skin and yet others, such as Enma, having red skin. They also posses a varying number of horns atop their heads. They act as the stewards of the dead, leading them to their places in the Afterlife, guarding Hell, and, in Enma's case, even judging the dead upon the expiration of their mortal lives.
