Yakyuken Cannonball.

Sakura, a high school girl; Mayu, a nurse; and Reiko, a company owner, are forced to play a game of strip rock-paper-scissors (yakyuken) by a doll calling itself "Ora Kamisama." The event is broadcast nationwide, becoming the subject of viewer bets. Drawn in by the prize money, the three women participate in the game, but it turns out to be far more than just a simple game of strip rock-paper-scissors.
