Under the influence of her father, a karate master, Miyuki Majima has practiced karate since the fourth grade and is now a genuine black belt holder. Her skills—demonstrated through kata performances, full-contact sparring with her sensei, and breaking boards and tiles—leave audiences awestruck. However, having grown up in an all-girls school, she harbors secret sexual desires and fantasies she's never revealed to anyone. Through interviews, these hidden aspects gradually come to light. The moment she receives a strike during sparring, her consciousness blurs, driving her toward climax through rape fantasies. She faces off against a muscular, dominant man, losing the match in bitter defeat, only to be subjected to an intense threesome rape, culminating in creampie after creampie. In despair, she loses control and urinates—this shocking sequence exposing the raw, true self buried deep within.
