One day the fairy Hummy from the land of music, Major Land, appears before them. The evil king Mephisto of Minor Land is planning to turn the legendary Melody of Happiness into the Melody of Misfortune. To prevent this from happening, Hibiki and Kanade transform themselves into Pretty Cure.
Kanade and Hibiki have to learn to work together to collect the scattered notes of the Melody of Happiness in order to recreate the score!
