The Super Girl (ザ?スーパーガール, Za Sūpāgāru, sometimes referred to as Supergirl) 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.
