Animation studio
is an anime series that debuted in TV Asahi (then known as NET, or Nihon Educational Television) in 1972. It is the fifth magical girl anime in history (the sixth if one counts Osamu Tezuka's Marvelous Melmo), and the fifth produced by the Toei Animation studio. While the show was fairly popular, it was not as popular as Toei's earlier magical-girl series, and is relatively obscure compared to its predecessors.
