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.

The war between the Iga and Sanada ninja clans is heating up, and a prominent gunsmith is on both clan's radar. Shinsuke Kakei, the gunsmith, is essentially a pacifist, but believes his weapons can bring peace to the land if put in the hands of the right group. Kasumi is sent to convince Kakei to come and work for them, and keep the guns out of the hands of the Iga. Of course Hattori, along with his sister Sayuri, have other plans for Kakei and his wife.
