Sally the Witch is considered the first magical girl anime and one of the originators of both the genre itself and the Cute Witch Sub-Genre.
Sally is the princess of a magical land. She comes to the human world to find friends her age, against her parent's will. She soon makes friends with two human girls after she saves them from burglars. Soon Sally's father sends Cub to bring Sally back. However Cub ends up staying with Sally in the human world, posing as Sally's five year old brother.
While Himitsu no Akko-chan's manga came first, Sally was the one to get an anime first. Both Sally and Akko were inspired by the popularity of Bewitched's Japanese dub with young girls.
