The main character, Kuuta, attacks the enemy with his club. Kazemaru sucks the enemy's spirit out of his body, and by destroying it, Kuuta can claim victory. Enjoy an all-new, unique co-op experience while playing Kuuta and Kazemaru at the same time! ■Another way to level up! Kisejima, where the game takes place, is divided into three areas with different challenges, from fighting enemies to escort missions. The player can also level up by escaping from the monsters that chase them, like in a game of tag, and by collecting mushrooms that grow in clusters to buy upgraded sticks. ■Setting: Kisejima Island The story takes place on Kisejima, a small island in the middle of the ocean. It is said that the power that lies dormant in the demon spirits here can be brought out by challenging them to trials, where ancient demons that were once defeated by Momotaro are summoned to battle. However, few of them ever returned from Kisejima alive. ■ Characters: Kuuta, a demonic warrior, and his spiritual partner, Kazemaru Kuuta, the main character, is the only survivor of the Demon King's army to face Momotaro in battle. He and Kazemaru, a mysterious ghost who lives in Kisejima, join forces to take on challenges of all shapes and sizes! ■Graphic design by KENEI DESIGN Kisejima may not be big, but the colorful graphics by KENEI DESIGN, with the dazzling green of the meadows, vast forests and plains with floating megaliths, offers a unique impact on emotions unheard of in any other action game. The creator of the game has created a mini world in which each location has its own unforgettable charm. ONI is an invitation for players to enjoy a small world experience for a change!
