Haruka Haruno, a young girl who wishes to be a princess, meets a strange boy named Kanata who encourages her dream and gives her a special charm. Ten years later, Haruka enrolls at the prestigious Noble Academy boarding school, where her new roommate, Yui Nanase, shows her around the campus. Whilst hiding in the woods over her embarrassment over revealing her dream, Haruka comes across Pafu and Aroma, two fairy siblings from the Hope Kingdom. Just then, they are approached by Close, an emissary from the evil Dys Dark organization, who traps Yui's dream of becoming an author in a Gate of Desperation to create a monster known as a Zetsuborg. As Haruka becomes determined to protect Yui's dream, her charm turns into a Dress Up Key, which Haruka uses with the Princess Perfume the fairies brought with them to become the Princess PreCure, Cure Flora. Using her new powers, Haruka manages to defeat the Zetsuborg and rescue Yui. Afterwards, Pafu and Aroma reveal they were sent in search of the Princess Pretty Cure by Kanata, who is revealed to the Prince of the Hope Kingdom.
