Mahou no Tenshi Creamy Mami

Ten-year-old Yuu Morisawa encounters a mysterious spaceship and receives a magical gift that will last for only one year. With help from the strange cats Nega and Posi, she can transform into an older girl, a power that unexpectedly leads to her being discovered as the new idol Creamy Mami.

Yuu must now live two lives at once: an ordinary schoolgirl helping at her parents' crepe shop and a rapidly rising singer whose true identity must remain secret. Between performances, magical troubles, and her feelings for childhood friend Toshio, she learns that becoming the person everyone admires does not make the problems of growing up disappear.
