3X3 Eyes

This game can be considered a side-story to the series. The player does not control Yakumo, but an ordinary high-school student named Kenichi Yamamoto. Accidentally, Kenichi comes into contact with the world of demons, and now he needs the help of Pai and Yakumo to be freed. The gameplay is standard Japanese-style adventure. The player interacts with the game world by selecting menu commands "Look", "Talk", and "Move". The game features animated cutscenes and (in its console incarnation) voice-overs.
