The episode begins with Kochou having Kotoha take a look at many old books, in hopes of getting any leads that can bring them closer to solving the mysteries surrounding Kotoha, while Mirai and Riko find a copy of Cinderella in the library and discuss their surprise at discovering the story of Cinderella exists in both of their worlds. Mofurun comments that she also likes the story.
Later that night, something strange happens and the girls find themselves in the story of Cinderella, except here the story is about Mofurun as Mofuderella. The girls must help Mofuderella get to the ball and find a way to return to their own world.
This episode provides examples of:
- And Now You Must Marry Me: After Gametts in the role of the Evil Stepmother challenges the Cures after accidentally being turned into a giant, he/she states that he/she will marry the Prince if the Cures lose.
- Fractured Fairy Tale: Once again, a Pretty Cure series has an episode where the main cast end up in the story of Cinderella. This time around, however, it is the mascot character rather than the pink Cure who ends up in the Cinderella role, and things just get weirder from there.
- Hurricane of Puns: In one of the subs of the episode, Mirai and Kotoha's (who got cast as mice in the Cinderella story) dialogue contains a lot of mouse puns.
- Perspective Flip: When discussing the story of Cinderella, Mirai discovers that in the Magic World's version of the story, it is the Fairy Godmother/Magician who is the main protagonist of Cinderella. They also discuss a few other stories, including Peter Pan where it is suggested that Tinker Bell is the main character in the Magic World's version.
