People with unredeemable, immoral and sinful souls can turn into an Oni demon when they die. Oni resemble ogres with horns and can have almost any color skin. They tend to hide because they don’t like to be seen by humans. While in the past Oni were considered evil, in our time they are oftentimes seen as protector more so then evil demons. Although somewhat less known, Oni also have the ability to shapeshift!
