The Oni is an enigmatic, mysterious creature that lives in the abandoned mansion on the outskirts of a town in Japan. Not much is known about the Oni, but it lives with many creatures that resemble it, and may have once been a human resident of the mansion. It is known to feed upon people that enter. It was shown that after the Oni kills, the victim becomes an Oni themselves. It seems to act like a virus - when the "virus" interacts with a sentient creature, it can turn them within moments into a horrific monstrosity, as with the pregnant cat in the original game. The Oni is a 11 ft. 7 inch tall, blue/violet creature with a large head. Its face is nearly identical to that of a human, except for its large eyes and nose.
