Having a great wrestler as his father, Ai trained in self-defense from an early age. Her father suddenly fell ill, and she inherited her dojo with Ai and her trainer, Kawase. Kawase, who has been aiming for Ai from before her, takes advantage of her father's absence and becomes familiar with her. One day, Kawase, who called Ai who took her unconsciousness during her lesson, attacked her under the guise of her self-defense practice training. To think that the dojo she inherited from her father would become the stage for rape!
