 Yuu Morisawa is a 10 year old girl living in her parent s crepe shop in Creamy-ga oka. Alien Pino Pino rewards her for helping him find his way home by offering a magic wand for an entire year. Two cat-like aliens named Nega and Poji help her discover her new powers. She transforms into an older self with a few magic words and is discovered by impresario Shingo Tashibana who needs a singer for a TV show. Under the name Creamy Mami, Yuu starts a very successful career at Parthenon Productions as an Idol pop singer and becomes more famous than the studio s other jealous star Megumi Ayase. However, she still has to cope with her daily life as a school girl which proves to be quite difficult considering the boy she loves, Toshio Ohtomo is Creamy Mami s number one fan. Yuu must preserve her real identity at all cost. Should anyone see her transform, she would loose her powers and remain Creamy Mami forever.
