The Super Girl[1] (ザ・スーパーガール, Za Sūpāgāru, sometimes referred to as Supergirl[2]) television series is a Japanese crime drama.

Supergirl, however, was primarily based upon the American television series Charlie's Angels and the softcore pornography films produced by Nikkatsu.

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.

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.
