Meanwhile, the Nightmares are moving into the real world.

A direct continuation of the former season, this series again follows the story of Nozomi Yumehara and her friends from Yes! Precure 5. The girls who had formerly lost their powers and bade farewell to their friends Coco and Nuts from Palmier Kingdom are resurrected as Pretty Cure by the mysterious woman Flora who also wants them to find her in a place called Cure Rosegarden. To go there, they need the magic Rose Pact and the powers of the four kings of countries surrounding Palmier. But a dark organization called Eternal is also striving to get to Cure Rosegarden by stealing the Rose Pact. Luckily, Precure get helped by new allies: the delivery-boy Syrup who can change into a giant bird and fly them anywhere they want and the mysterious and beautiful fighter Milky Rose stand alongside Pretty Cure to protect what is really valuable.

When people dream, they express their utmost desires and emotions within the confines of their mind; but when their strong emotions cross the border into reality, the dream can turn into an uncontrollable nightmare. Touko and Rinko are sisters known as "yume tsukai" (dream users), and their job is to take care of these nightmares. Using toys as weapons, the girls must both destroy the nightmare and return the dream to its rightful owner before the nightmare does any sort of serious damage. Have no fear, Touko and Rinko are here! (Source: Anime-Planet)

The story is set in the not-so-distant future. Five "Black Points" suddenly appeared around the world as portals to parallel worlds. Immediately after, strange creatures began their invasion from these portals. These creatures are the inhabitants of five worlds—the same worlds in different timeframes. In order to ensure their own future timeframe survives, each of the five invasion forces battle to wipe the other future timeframes out. The key is one card-shaped device. (Source: ANN)
