A long time ago, a young girl named Haruka Haruno met up with a strange boy named Kanata who gave her a key while having her promise to never give up on her dreams. A few years later, now 13 years of age, Haruka attends the Noble Academy boarding school while still cherishing her dreams of becoming a princess like from her picture books. One day, she encountered two fairy creatures from the Hope Kingdom: Pafu and Aroma, who were followed by strange monsters. The fairies told her that the monsters are the creations of a witch named Dyspear who wants to bring despair to the world by locking dreams away in the Gate of Desperation. With no choice, the fairies gave Haruka a Princess Perfume, becoming Cure Flora, a Pretty Cure to oppose the dark witch's Dys Dark followers. Later joined by Minami Kaido and Kirara Amanogawa, as Cure Mermaid and Cure Twinkle, Haruka forms the Princess PreCure Team to collect Dress-Up Keys needed to open the Gate of Dreams while protecting people's dreams from Dys Dark's forces.
