Synopsis

While waiting for Kotoha in the library, Mirai and Riko come across the Magical World's version of Cinderella. Later that night, the Linkle Smarthon glows and the girls suddenly find themselves as characters in the book, with Mofurun in the role of "Mofuderella". Following their roles, Riko, the fairy godmother, along with Mirai and Kotoha, the friendly mice, help Mofuderella get to the ball where the prince, played by the Headmaster, awaits. However, the wicked stepsisters, played by Batty and Spalda, bring out their own magician, Yamoh, who transforms Gamets, the wicked stepmother, into a giant. After winning a dance battle, the Cures use their magic to turn the stepmother back to normal size. As the girls struggle to get to the way back to their world before their carriage disappears, Mofuderella uses the magic of her glass slippers to create a Rainbow Carriage and help them get there in time. Upon waking up from what was seemingly a dream, the girls are surprised to find the Rainbow Carriage is there in the real world and the book's contents have been changed to feature Mofuderella.
