Magically and mysteriously, Hime-chan meets someone who is the mirror image of herself, but she's a princess! 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?
