Aku no Onna Kanbu: Full Moon Night

Based on the erotic game by Lune. Within the Great Lunarium, failure is met with punishment, a principle that applies even to executives. The enforcement of this rule falls to Katsuma, the organization's sole male executive. He uses his position to subject female executives who have failed in their duties to a hellish ordeal of sexual pleasure. Having endured years of bullying from these arrogant women, Katsuma has cultivated a profound enmity toward them, and he now seizes the opportunity for vengeance. His upcoming targets include two figures: Ephanatica, whose demonic appearance is the cost of her powers and who demonstrates extreme loyalty to the Great Lunarium; and Diana, an earthling who betrayed her people and who possesses the largest breasts among the executives.
