Prior to the beginning of the series, the three of them defended Hope Kingdom against evil thanks to the power of the twelve Dress Up Keys.
In episode 29, Chieri, Yura and Sei appeared in a dream-like world resembling Hope Kingdom in the past that Haruka, Minami and Kirara entered when they were looking for their Dress Up Keys. The group talked over tea and Haruka and the others told them about how they were about to give up on their dreams because of what they had lost. Suddenly, a Zetsuborg attacked them and an illusion of Dyspear appeared as well. As they all try to run from the attack, Haruka and the other Cures remembered that it was their duty to protect everybody's dreams and regained their resolve. Once they did, the three past Cures granted them temporary Dress Up Keys allowing them to transform once again and defeat the Zetsuborg. Soon after, the three of them revealed that they were the original Princess Pretty Cure and warned them about an impending powerful darkness. Because of the despair the girls felt, they ended up feeling that same despair, which affected them. Now with their resolve restored, the past Cures departed, granting them the Premium Sakura, Sango and Ginga Dress Up Keys.
