television series is a Japanese crime drama. Originally broadcast between April 2, 1979, and March 17, 1980, lasting 51 episodes, the series featured an all-female cast, not unlike the earlier series Playgirl. Supergirl, however, was primarily based upon the American television series Charlie's Angels and the softcore pornography films produced by Nikkatsu.
Despite the superficial similarities, Supergirl is vastly different from Playgirl. Featuring far more serious plots and less comic relief, as well as highly eroticised situations wherein the characters wore a variety of revealing and fetish outfits, including bikinis and schoolgirl uniforms, these elements of the series were a deliberate attempt by its producer Toei to create a more "adult" series. This can even be seen in the episode titles, such as episode one, "Seven Sexy Cats Make Their Explosive Debut", or episode nineteen, "Nude Battle Against the Wolf Pack".
The main characters of the series are members of "SG7" (short for Super Girl Seven), an all-female detective agency. Their leader was portrayed by Yōko Nogiwa; the other primary actors in the series are Janet Hatta, Linda Yamamoto, Rei Maki, Reiko Itsuki, Jun Izumi, Naomi Tanaka, Emi Shindo, and Akiko Hyuga.
