A costume play adult video styled after special effects heroines, featuring Yuu Kurasu as a beautiful, glamorous woman. Her face is almost entirely concealed, but beneath the mask she struggles to breathe while desperately performing. Former female investigator Ayaka Shiroto was killed in the line of duty by a gang of robbers, but the Soid Corporation reuses her body as an experimental subject for their cutting-edge Project Sigmnoid, resurrecting her as the super enforcer Sigmarizer. However, when Sigmarizer uncovers Soid Corporation's terrorist activities committed for insurance fraud, she storms the company headquarters—only to fall victim to a treacherous trap.
