Nozomi and friends are back, their role as Precure far from over. The girls are given new powers by the mysterious Flora, who awaits their arrival in a place called the Cure Rose Garden. But to reach that garden of legend, they have to use a magical relic known as the Rose Pact. Problem is, our heroes don't know how to use the thing. This leads them to seek help from the four monarchs of Palmier's neighboring countries. Not to make things too easy, dark forces are afoot once again. An evil organization, Eternal, is keen on adding the Rose Pact to its ever-growing collection of treasures. To make matters worse, the director of this dastardly museum seems to have a vested interest in the Cure Rose Garden. Fortunately, a new story brings with it new allies. Enter Syrup, the courier boy with a bad attitude. His desire to reach the Garden is pure, but who exactly is he? And for that matter, who's the new girl in town and why does she smell like roses?

The dying planet of Eltria is the only home of Kyrie Florian, her older sister Amitie, and her parents, who are scientists researching ways to save it. Unfortunately, the Florians must leave the planet behind to seek medical care for their father, who has contracted a lethal illness. Even with treatment, the survival rate of Kyrie's father is minuscule. Refusing to give up on her father and Eltria, Kyrie goes against the wishes of her sister and runs away from home to the peaceful planet of Earth in search of a solution. There, Kyrie and her childhood friend, Iris, pursue Earth's magical protectors—Nanoha Takamachi, Fate Testarossa, and Hayate Yagami. Nanoha and her companions possess the key to fulfilling Kyrie's objective, and the young girl must do whatever it takes to obtain it. However, it proves difficult for Kyrie, as the protectors do not easily yield to her provocation. Furthermore, Amitie soon arrives on Earth to stop her younger sister's reckless actions and bring her back home, further complicating the already delicate situation.

IDOLiSH7 is more successful than ever, but no one is smiling because a new threat has taken the stage: the debuting idol group ŹOOĻ. Managed by the nefarious entertainment executive Ryou Tsukumo, they will stop at nothing to get their way, resorting to all kinds of underhanded tactics to bring down their rivals. TRIGGER's image has already been ruined by scandal, and IDOLiSH7 and Re:vale are headed for the same fate—or worse. Meanwhile, Zero, the legendary idol who disappeared 15 years ago, continues to haunt the present through those he left behind. His manager seems to be in contact with Tsukumo for his own schemes, and Zero's songwriter reveals himself in a letter after having been missing for years. IDOLiSH7 finds an ally in Re:vale to thwart ŹOOĻ's plans while trying to make sense of Zero's colleagues' actions, but it may be impossible for everyone to emerge unscathed.

The anime will take place 10 years after FLCL Alternative and will center on a high school boy and girl.
