The escalating conflict between the True Female Body Torture Research Institute and the Moriyama Group intensifies, as the True Female Research Institute led by Tsuji mar formally declares war against the False Female Research Institute and the Moriyama Group, igniting an even fiercer battle between the men. Fearing the collapse of their criminal enterprise, the Moriyama Group decides on retaliation against the Female Research Institute—by kidnapping Hazuki Naho, the mistress of Research Institute executive Baba who works as a hostess in Kabukicho—and subjecting her to pleasure torture. After successfully abducting Hazuki, the Moriyama Group studies DVDs released by Baby Entertainment's Female Body Torture Research Institute to develop their own unique philosophy of guiding women to pleasure. In the process, the desires of men and the struggles of women evolve into a new and twisted form.
