One place that Oni appears in Ao Oni is in the library.
A few 1st tier games based on Ao Oni are Abe Oni, Aka Oni,Akame Oni, and Ao Oni Plus.
It is thought that the Oni is inside the mansion because he was a former resident of Ao Oni.
The Oni in Ao Oni is a creature with light purple skin and large black eyes.
When an Oni starts following you in the game Ao Oni, the only place to hide is in a closet.
