This sequel directly follows the previous season's storyline, chronicling the escapades of Nozomi Yumehara and her comrades from Yes! Precure 5. The girls lost their magic abilities and recently bid farewell to Coco and Nuts from the Palmier Kingdom. However, the mysterious Flora reanimated them as Pretty Cure. Their paramount objective is to locate Flora in Cure Rosegarden by harnessing both the Rose Pact and the four kings' powers from neighboring lands. Unfortunately, a dangerous organization called Eternal is competing with them, vying for exclusive rights to the Rose Pact and Cure Rosegarden. Luckily, Syrup, a carrier-pigeon who morphs into a colossal bird, and Milky Rose, a stunning warrior, are new allies. Collectively, they band together to ensure that their true purpose is safeguarded.
