Long ago, there was an evil king who loved nothing more than to rape and torture beautiful women. He was so evil that it became taboo to even speak his name. He was slain by a woman that killed him through sex, but 300 years later he is reborn. In order to defeat this ancient evil, the greatest female warriors in the world face off to see who is worthy of fighting and defeating this terror.

Monzetsu Fighter is a card battle game where you play as a female warrior fighting other female warriors and occasionally a boss. Battles simulate rape fights and cards represent different ways of sexually attacking an opponent. As health decreases, characters get cuts, bruises, and lose clothes. The fight ends when one of the combatants passes out, of as the title says, faints in anguish.
