Bringing the Princess Perfurme to Dyspear, Twilight receives a new Black Key to use with it. This causes a reaction in the Dress-Up Keys, which teleport Haruka and the others to the Hope Kingdom. Separated from the others, Haruka follows the light shining from her key and comes across Kanata while encountering some Zetsuborgs. Each of the girls are guided by their keys to a corresponding building, where they are greeted by the Princess Pretty Cures of the past, who warn them about the fourth Princess Perfume being used for darkness. As the Cures head towards Hope Kingdom's palace, Minami and Kirara are briefly stopped in their tracks by Shut and Lock respectively, while Haruka hears about Kanata's sister, Towa, who suddenly went missing one day. After everyone assembles at the palace, they are confronted by Twilight, who Kanata recognises as Towa. Rejecting such claims, Twilight uses the Princess Perfume, transforming into the Black Princess.
