ONI : Road to be the Mightiest Oni

The story takes place on Kisejima, a small island in the middle of the ocean. Here, it is said that the power that lies dormant within the local demon spirits can be drawn out by challenging them to trials, where ancient demons who were once defeated by Momotaro are summoned to battle. However, few have ever returned from Kisejima alive. The protagonist, Kuuta, attacks the enemy using his club. Kazemaru sucks the enemy's spirit out of its body, and by destroying that spirit, Kuuta can then claim victory. Enjoy an all-new, unique co-op experience by playing both Kuuta and Kazemaru at the same time!
