By day, she is a gentle and devout nun, but when monsters from the demon world threaten the earth, she transforms into the naked superheroine Saint Flame. Her figure is both beautiful and seductive, a presence powerful enough to overwhelm any demon. This time, however, she faces a monstrous foe with a unique ability—an aberration wielding living tentacles as weapons. Overpowered and captured, she is rendered helpless. The evil mastermind takes advantage of her vulnerability, cruelly exploiting her humiliation while roughly groping her big tits, stimulating the very source of her power: her shame. But this strength is fleeting. With her comrades taken hostage, she is completely at the enemy's mercy. Struck unconscious with a whip, she is taken to the enemy's lair, bound to a cross, and stripped of her nunchaku—the weapon that once defined her. In its place, the enemy implants devices directly into her body. Again and again she is tormented, pushed relentlessly toward her breaking point.
