Majokko Megu-chan

Majokko Megu-chan (魔女っ子メグちゃん, lit. Little Meg the Witch Girl) is a popular magical girl anime series. The manga was created by Tomô Inoue and Makiho Narita, while the 72-episode anime series was produced by Toei Animation between 1974 and 1975. This series is considered an important forerunner of the present day magical girl genre, as the series' characterization and general structure exerted considerable influence over future shows in the same genre. Most notably, several of the show's recurring motifs were recycled in Toei's Sailor Moon, AIC's Pretty Sammy, and (to a lesser degree) Wedding Peach.

Plot
Megu is sent to Earth in her early teens, she is adopted by Mammi Kanzaki, a former witch who gave up her royal ambitions to wed a mortal. Mammi bewitches her husband and their two children, Rabi and Apo, into believing that Megu has always been the eldest child of the family. Under Mammi's tutelage, Megu learns to control both her abilities and impulses in order to prove her worthiness for the crown. This Rite-of-Passage subtext is continued throughout the series.

Why it Rocks
Awesome animation.

Great stories.

Cool characters especially Megu herself.
