Mana receives a treasured wedding dress that once belonged to her mother and grandmother, only for a mysterious man named Matthew to pull her into a world shaped by the past. There she can once again meet her beloved grandmother and her old dog Maro, but something is wrong: Rikka and Alice have vanished from the memories that should include them.

As precious moments are rewritten, the damage begins spreading toward the future itself. Mana and the other Precure must protect the bonds that made them who they are before their shared history, and the tomorrow waiting beyond it, disappear.
