Most notably, several of the show's recurring motifs inspired Toei's Sailor Moon, AIC's Pretty Sammy, and (to a lesser degree) Wedding Peach.

A free spirit in the purest sense of the word, Megu-chan discovers emotions she had never known existed – loneliness, compassion, grief, love, desperation, and (perhaps most importantly) self-sacrifice.

As the story progresses, she proves the nobility of her character through the various trials and tribulations of youth, evolving from a willful and rather selfish little girl into a kind, generous, loving young woman.

She battles monsters, demons, and rival sorcerers (including her nemesis, Non), but quickly realizes that her true enemy is the darker side of human nature.

Complicated social issues such as domestic violence, substance abuse and extramarital relationships were introduced, while loss and mortality frequently underscored Megu's hijinks.

Rabi had an arsenal tricks aimed at catching his "big sister" disrobed, from yanking the sheets off Megu's bed in the morning to using a fishing rod to lift her skirt.

Initially overlooked as a minor effort due its relative obscurity following its airing in the seventies, it nonetheless formed a template on which many later scenarios were based.

The program's impact on Japanese popular culture should not be underestimated; thematic descendants include the entire magical girl genre, along with some degree of bishōjo, lolicon and hentai material.

Megu's effect on Japan's burgeoning manga industry has yet to be documented, but considering the vast number of shōjo titles currently available, it is safe to assume that Majokko Megu-Chan's animated adventures must have inspired at least a few of them.

The series gained moderate recognition after it reached the European market (with the heroine's name Anglicized to Meg in the French dub, and changed to Bia in the Italian, Portuguese, and Polish versions), but remains largely unknown in the English-speaking world, as it has never been officially translated into English.
