Kaguya, a young girl with a hazy memory of her past, begins to experience vivid dreams of a boy she cannot recall. One night, he suddenly appears in her room, taking her away to a distant world where she discovers a shocking truth: the existence of multiple parallel Earths, each with its own unique reality. As the boy, who claims to be her protector, explains that the Earths are on the verge of destruction, Kaguya must make a crucial choice: join him on a mission to save the chosen Earth, abandoning all others, or find a way to preserve the diversity of the multiverse.
