Shoukoujo The Animation follows the tragic and sexually degrading ordeal of the innocent and naive heiress, Sena. After her father's death, Sena is left at the mercy of her cruel stepmother, Misa, and wicked stepsister, Airi, who conspire to seize her inheritance. Their method is to systematically break her spirit through relentless sexual torture and humiliation. Sena is first forced upon her lecherous uncle, who eagerly defiles her. This is just the beginning of her nightmare, as Misa and Airi auction off her virgin body to crowds of depraved men. Throughout the series, Sena is subjected to brutal and non-stop gangbangs, forced to service dozens of men at once in public orgies. Her body is treated as a communal fucktoy, her holes stretched and filled repeatedly. She is forced into acts of public exhibitionism and sold to perverted clients who exploit her in every conceivable way, pushing her deeper into a spiral of sexual slavery and despair from which there is no escape.
