Azalea Latwick is an esper with telepathic abilities who suffers complete amnesia, leaving her unaware of her identity or past. Residing on the colony planet Dinahl, she begins hearing insistent voices directing her to a specific park atop a skyscraper. There, she meets four other amnesiac individuals—Locke, Eno, Umoth, and Neia—each possessing distinct superhuman powers: Eno wields psychic power, Umoth has X-ray vision, Neia can teleport, and Locke manipulates electricity. All five were summoned by an unseen entity under identical conditions of memory loss.

Azalea's telepathy enables mental communication and perception, complementing the abilities of the group. They are collectively tasked with a critical mission to save humanity, promised the restoration of their memories upon its completion. This mission requires their collaboration across interstellar travel, leveraging their combined powers to overcome challenges.
