Aku no Onna Kanbu: Full Moon Night

It is based on the pornographic video game Lune. Failure must be penalized, even if you are a high-ranking CEO. It is Katsuma, the lone male executive of the Great Lunarium, who is responsible for implementing this regulation. He abuses his position of command by inflicting sexual pleasure hell on female executives who fail to do their duties. Over the years, he had developed a strong resentment towards these arrogant ladies who had mistreated him on a daily basis, and now it was time for him to exact his vengeance. His next targets are: Ephanatica, who is very devoted to the Great Lunarium and has been given the look of a demon as a recompense for her talents; and Diana, an earthling who deserted her people and has the biggest breasts among the executives.
