Megu Kanzaki is a powerful (but accident-prone) young witch who comes to Earth as part of her initiation into larger society. Megu is a contender for the throne of the Witch World but knows very little of human relationships.

Initially, Megu experiences severe difficulties adapting to 'normal' society, even at the simplest levels. Family relationships are completely beyond her. She argues with her Father and squabbles constantly with her younger siblings, Rabi and Apo, who love to play tricks on her. She confronts Boss, the school bully, in an escalating battle of wills and gets into trouble with her teachers. She falls in love with the new boy and weeps in secret when he returns to his home country. Basically, her behaviour resembles that of any other girl her age, given the social norms in mid-seventies Japan. As with the magical girl programs of the sixties, the main focus was on family and friendship; domestic disputes were normally handled with light-hearted humor.
