Mai Kazuki, a first‑grade student, dreamed of becoming a magician but her talent was not yet strong enough to join her grandparents" Magiccarat ensemble in the circus. One afternoon she watched a beam of light slip into an odd heart‑shaped mirror. The glow was actually Topo, a mirror sprite, who possessed her beloved plush flying squirrel and presented her with a bracelet bearing the four card suits. The charm could morph into a bubble wand, turning Mai into the eighteen‑year‑old wizard Magical Emi, who then used her powers to aid others and perform with her grandparents.
