Uniform Virgin: The Prey (1986)

Despite his reputation as the Paul Morrissey of "pink" films, concerned as he was with the effects of urban alienation on the disenfranchised members of society, cult softcore director Hisayasu Sato was not above the occasional foray into all-out sleaze. This viciously sadistic tale of an orgy of rape and violence in a Japanese high school, scripted by co-star Taketoshi Watari, pushes the brutality envelope a bit far even for Sato, without any of the redeeming characterizations or social observations seen in his usual work. Hiromi Kurita, Megumi Hayase, and Yoko Aimoto are along for the distasteful ride.
