Himeko is an energetic, cheerful tomboy who has a catch-phrase to cheer herself up ("Ike, Ike, go, go, JUMP!"). Yet she somehow lacks the courage to tell the older boy at school that she has a crush on him. Perhaps she's just not feminine enough?

Erika, from the Magic World, has come to give Hime-chan a present that she's invented, a magical ribbon, that will allow her to turn into the image of anyone else for one hour. This ought to help solve Hime-chan's problem, shouldn't it?
