Kanata informs the girls of a Dress-Up Key located somewhere on Noble Academy's campus in a "place where dreams are overflowing". Hearing rumors that the dorm mother, Shirogane, possesses a unique key herself, Haruka and the others follow her through a secret passageway leading to a beautiful rose garden. There, they come across a windmill where Shirogane has kept plaques of all the graduated students' dreams, which shine when Shirogane uses her key to open up the windows. Just as the Dress-Up Keys react to the dreams, Close suddenly appears and uses all the graduates' dreams to turn the windmill into a Zetsuborg, trapping Shirogane inside. Discovering Yui has followed them, the girls reveal their identities as Pretty Cures in order to protect her. Although Haruka's purifying attack initially fails, the Cures' remain determined to protect the captured dreams and combine their powers to defeat the Zetsuborg, receiving new Elegant Dress-Up Keys in the process. As Dyspear suddenly appears before Close and the Cures, Kanata prepares to send some magical items to the Cures.
