HetaOni is a Hetalia fangame based on the popular horror RPG game Ao Oni by noprops, first made by Tomoyoshi with RPG Maker XP (this version was just shown as videos) and then programmed with RPG Maker VX by Pianodream and NeoKyno to make it playable.
The game is about the Axis Powers and the Allies being trapped in a mansion, but legends say that this mansion was haunted.
