A tomboy who just wants to mess around gets a magical ribbon that forces her to understand literally everyone else's perspective. The show builds its entire charm from watching Himeko accidentally become more human every time she pretends to be someone else. Sixty-one episodes of transformation sequences that are actually about learning kindness instead of defeating evil, with a boy who stays genuinely likeable the whole time because the show never forgets that romance is just two people figuring each other out.

Himeko Nonohara is a thoroughgoing tomboy whose life turns strange when Erika, princess of the Magic Kingdom, comes to Earth looking for a human girl who looks just like her. Erika has made a magical item to prove she is worthy of succeeding to the crown, and Himeko is the one who must test it: a hair ribbon that lets her transform into any other person she sees. The story follows Himeko's adventures with the ribbon and her budding romance with Daichi, the boy who discovers her secret. Comedy, fantasy and mahou shoujo magic mix with a romance that grows alongside her secret double life.
