Mai's grandparents own a magic troupe called Magicarrat. Mai always dreams about becoming a fantastic magician, but she, as an elementary school pupil, is too young to perform magic tricks. Her grandparents try to expand the scale of Magicarrat by including dancers and acrobats in their magic show.
One day, she encounters a fairy in a mirror, Topo. Topo gives her magical stick, which has the power to make her wish come true. Mai uses the stick to transform herself into a genius magician, Magical Emi! As Mai wishes, Magical Emi becomes the superstar of the Magicarrat.
In the splendid magic show with songs and dances, Magical Emi performs amazing illusions and magic tricks for the audience. This is a third series of Magical Girl Series.
