A rookie reporter named Ichika, who is investigating the frequent disappearance of women, is drugged and taken to a facility called "Pigsty," where women are brainwashed and turned into livestock. There, Ichika is stripped naked, whipped, and treated as a "female pig," enduring hellish days. Her humanity is destroyed through inhumane torture! In order to escape the fear and pain, Ichika accepts being immersed in extreme pleasure. With beast-like roars and orgasms! This is the form she was processed into, as a "sex-craving animal" who has abandoned her humanity.
