Wearing a white holy garment, Shizuka Minamoto exterminates demons with her fists. Although she is a student at a prestigious female university, she secretly exterminates monsters that disrupt the world. Possessing extraordinary physical abilities, she transforms into the Saint Fist when in a pinch. The power of exorcising demons, passed down from the Warring States period, brings out the user's physical abilities to the limit, but it places a great strain on the body, and if she remains transformed for a long time, her body becomes sensitive and breaks down. This slight weakness is discovered, and the monsters take revenge on Shizuka! They torture her navel, and the witch's tentacles wrap around her body, tormenting her. She is beaten so badly with a whip that she foams at the mouth like a crab and faints. Then, her battered and sensitive body is sexually subjugated. In the end, she is impaled by Shizuka's holy sword and dies... [BAD END]
