A girl gets magic powers from a broken mirror and spends 61 episodes solving the smallest, warmest problems in her neighborhood. There's no villain, no world-ending threat, no reason to watch except the pure pleasure of seeing someone use transformation magic to help a friend find their lost cat or cheer up a lonely classmate. This is what magical girl looks like when nobody is trying to save anything, just a kid making the ordinary day slightly more magical for everyone around her.

Akko is a bright, energetic fifth grader whose father is a newscaster and whose mother writes picture books. She treasures a small mirror her father gave her, until her absent-minded mother accidentally breaks it. Under a full moon, Akko buries the pieces in the garden and goes to bed. She is woken by the gentle voice of the Queen of the Mirror Kingdom, who thanks her for caring for the mirror and gives her a magical compact. When Akko sings the magic words, she can turn into anything she wants. The result is a comedic magical girl story built around that transforming compact.
