In this high-concept fantasy from director Hitoshi Nimura, three of the genre's most famous actresses—Nana Miyachi, Rin Ayase, and Momo Nakamura—collide in a "mixed" encounter. While the export title uses aggressive slang, the film is a classic Futanari production focusing on the unique anatomy and chemistry of the performers. The narrative explores the "mixing" of their hidden members in a series of group scenarios, moving from individual demonstrations to an intense, synchronized finale.
