Mahou no Star Magical Emi: Kumo Hikaru

Kazuki Mai, an elementary schoolgirl, wanted to be a magician but her skills weren't good enough for here 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.
