Space age fairytale from the faraway future... Planet Magracia is a center for commerce with busy space traffic. A girl named Lilly is intrigued by an enigmatic new girl in her school. She's the same age as Lilly but mature compared to other students in her class. Regarded aloof, she hasn't made any friend yet, it seems. Her name is Hikari. Lilly can only watch her from distance, hoping for an opportunity to talk to her. Then one day, a strange cat-like creature shows up in class, changing their ordinary life.

Hikari is a girl whose mother Mari has fused with a spaceship. Traveling in the spaceship, Armadillo, Hikari experiences things and encounters people, including a strange boy called Romeo who emerged from the extracted noise she came across on the Web, and her long-lost father Raven.

Atsuko "Akko-chan" Kagami (known variously as "Stilly," "Caroline," or "Julie" in Western versions of the anime) is an energetic elementary school girl who has an affinity for mirrors. One day, her favorite mirror which was given to Akko by her mother (or in some versions, by her father, as a present from India) is broken, and she prefers to bury it in her yard rather than throw it to the trash can. In her dreams, she is contacted by a spirit (or in some cases the Queen of the Mirror Kingdom) 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.
