Love Momozono, a cheerful middle schooler who tends to care more about others than herself, gains the power to become Cure Peach when agents of the Labyrinth Kingdom attack a dance show, hunting for the despair the crowd carries. She's joined by classmates Miki Aono and Inori Yamabuki, who become Cure Berry and Cure Pine, in protecting Tart and the infant Chiffon, visitors from the Sweets Kingdom that Labyrinth wants for its own ends. The three Cures stand against Labyrinth's ongoing hunt for a mysterious power called Infinity.
