Plot
Atsuko Kagami, or her nickname "Akko-chan" for short, is an energetic elementary school girl who has an affinity for mirrors. One day, Akko's favorite mirror given by her mother gets broken, and buries it in her yard rather than throw it in the trash. In her dreams, she is contacted by a spirit who is moved that the little girl would treat the mirror so respectfully and not simply throw it away. Akko-chan is then given the gift of a magical mirror and taught an enchantment that will allow her to transform into anything she wishes.
