Tsubomi Hanasaki is a girl in the second grade of middle school who likes flowers and plants. One day she experiences a weird dream. In that dream, a large blooming tree appears. Suddenly, it loses all of its flowers and two fairies appear. A few days later after Tsubomi has transferred to Myoudou Academy, suddenly the fairies from the dream appear before her and plead to Tsubomi to become the legendary warrior Pretty Cure, and protect the Heart Tree. However, Tsubomi declines as she doesn't think that she would be able to do that. However, a mysterious enemy suddenly strikes and steals the Heart Flower of her classmate, Erika Kurumi. Now she doesn't have a choice. To retrieve Erika's Heart Flower, she has to transform into a Pretty Cure and fight.
