The world has fallen, and the Precure were defeated. Caught by surprise by a massive attack from all their enemies at once, they had no choice but to run and scatter all over the world. Even so, the Precure will not let the world fall into darkness: though the light of the stars is gone, the Precures' hope still shines on. (AU involving all seasons up to Hugtto.)

Frighton, the world of fear, has become active years after its initial defeat. The disturbance can be sensed all the way from Earth, where a small bat fairy named Boo sets out to find promising young women to become new Pretty Cure warriors and stop the fear from spreading once again.

Mei Tarano lives a simple life until she comes across an injured fairy, Mocchi who informs her that Earth is threatened. Through a series of events, Mei awakens as Cure Daisy and along with Cure Flare, Maple and Snow she attempts to save the planet.
