Known as the Japanese-American superheroine United Woman, Lulu arrives in Japan to pursue Nicholas Wagner, who has committed serious crimes on American soil. Nicholas is being harbored by Nakamura, the boss of Japan's secret organization Ryu-shu and Lulu's close friend. Lulu obtains intel on his location and heads to their hideout. However, she is met by Saito, Ryu-shu's enforcer, who once had his right hand severed by Lulu during the thwarting of a criminal plot and now wears a mechanical replacement. Though Lulu fights with overwhelming strength, Saito withstands her assault just long enough to knock her unconscious with a neurotoxin called Chlorodaine and capture her. Refusing to yield, Lulu grows furious at Saito's actions and resolves to defeat him. Following Nicholas' advice, Saito successfully damages Lulu's costume with a chainsaw, deeply wounding her pride and solidifying her determination to destroy Ryu-shu. But Nakamura has another plan—one that thrusts Lulu into an unfamiliar world of eroticism unlike any battle she's faced before. Weakened by Chlorodaine, Lulu is made to enter a euphoric state and forced to perform lewd dances. Her humiliation is then exploited as footage for an international heroine auction attended by powerful figures. The elites force Lulu into degrading dogeza bows, subject her groin to intense vibrations, and jam an ice phallus deep into her private parts. The United Woman is utterly defiled, her body corrupted as she transforms completely into a depraved woman. 'BAD END'
