Ai, whose father was a great wrestler, had been training in self-defense since she was young. One day, her father suddenly fell ill, and Ai and her trainer, Kawase, took over the dojo. Kawase, who had been eyeing Ai all along, started to act familiar with her in her father's absence. One day, during a lesson, Kawase summoned Ai after she made a mistake and attacked her under the pretense of practical self-defense training. Who would have thought that the dojo inherited from her father would become the stage for a rape!
