In the chaotic aftermath of a city-wide cataclysm, special investigator Kyoko and her partner Miki navigate the ruins of a metropolis now teeming with 'Infected' — humans twisted by a hyper-sexualizing virus into depraved monsters craving nothing but brutal copulation. Their mission to find the outbreak's source quickly devolves into a desperate fight for survival. Kyoko is captured and subjected to an endless, violent gangbang by a horde of slobbering mutants, her body used as a mindless breeding hole. The series graphically details her violation by monstrous cocks and grotesque tentacles, pushing her past the brink of sanity. The aphrodisiacal nature of the infection twists her agony into overwhelming, addictive pleasure, systematically breaking her will and corrupting her sense of self. Episode by episode, we witness Kyoko's horrifying transformation as the virus remolds her mind and body, turning the once-proud investigator into a whimpering, perpetually leaking vessel, begging for the next monstrous seed to fill her womb.
