Japanese developer KAYAC has announced Ketsu Battler, a new butt battling game they’re making in collaboration with CoroCoro Comic.

The new butt-sword battling game is launching for Nintendo Switch in Japan later this year, on December 12th.

Here’s a brief blurb on the game, plus its reveal trailer:

Let’s have an ass battle! A competitive game where you and your friends can shake your butts as hard as you can and have a good laugh!

Ketsu Battler is an action game exclusively for 2-player battles. The most unique feature of this game is that you do not hold the controller with your hands, but control the character with your buttocks. By shaking your buttocks, you can wield weapons, and by building up power and thrusting your buttocks, you can perform special moves. The game is easy to relate to for elementary school students, who are the target audience of CoroCoro Comic, and is sure to be a lot of fun with friends.
