Ao Oni

Ao Oni is a Japanese indie horror game, created with RPG Maker XP. It follows the adventure of four teenagers who go into an abandoned mansion (which is supposedly haunted) in order to investigate...

Provided inspiration for Heta Oni, an Axis Powers Hetalia-themed parody/reinterpretation. Other games inspired by it include Aka Oni, Siro Oni, Niji Oni, Hakkyou Oni, Gon Oni, and Ao Oni S.

Keep in mind that with different revisions of the game may have significant differences within the plot.
