Nagisa Misumi and Honoka Yukishiro are as different as can be. Nagisa is athletic while Honoka is studious, and although they go to the same school, they share almost nothing in common—until a meteor shower one day introduces two unlikely guests into their lives: Mippuru and Meppuru, refugees from the Garden of Light, which has fallen to Darkness. Granted new and astonishing powers, Nagisa and Honoka transform into Cure Black and Cure White, magical guardians of the light—together, they are Pretty Cure.
