In the bustling city of Neo-Tokyo, where skyscrapers mingle with hidden magical alleys, Mimi lives a simple life as an ordinary girl attending Sunny Hills Elementary. Orphaned at a young age, she stays with her kind aunt who runs a small bakery. With her short stature, tiny skirt and cropped blouse always fluttering in the breeze, Mimi dreams of grand adventures. Unbeknownst to most, she possesses a spark of latent magic that causes minor mishaps, like flowers blooming in her wake or toys coming to life during playtime. Her days are filled with school friends, after-school snacks, and secret explorations of the city's enchanted underbelly.
