Masae Maeda

"Shiro" is a black cat who loves her family very much. She loves them so much she wants to help them out in times of need and trouble…but it’s difficult to do this if she’s just a cat. So one night, she wishes on the moon to make her able to help, and the next day, she has turned into a human girl.

Kazuki Mai, an elementary schoolgirl, wanted to be a magician but her skills weren't good enough for her to join her grandparents' Magiccarat troupe. One day she sees a light enter a strange heart-shaped mirror. The light is actually a mirror fairy named Topo, who takes over her favourite stuffed toy, a flying squirrel and gives her a bracelet with the 4 card suits. The bracelet can turn into a bubble wand which transforms Mai into the 18 year old magician Magical Emi, who uses her magic to help people and participate in her grandparents' shows.
