Female ninja "Mika Tsuki" once belonged to a secret organization known as "Dark Fang," but she left the group and had been living peacefully as an ordinary citizen. One day, her fiancé is kidnapped by Dark Fang. Upon learning this, Mika Tsuki infiltrates the organization's headquarters alone to rescue him. However, she is surrounded by Dark Fang soldiers, overpowered in combat despite her resistance, and ultimately captured. She is then subjected to brutal torture: forced to urinate directly into her fiancé's mouth, anal beads are inserted into her anus and mercilessly manipulated. In front of a crowd, she is made to defecate publicly and receives a glycerin enema using an extremely thick syringe. Finally, her mask is forcibly removed, and she suffers the ultimate humiliation as low-ranking ninjas spray their filthy urine onto her face in a degrading bukkake.
