A centuries-old mystery walks into the present as a boy who has no idea what he's stumbled into. The white-haired children are not what they seem, and neither is the girl with the crescent moon, every answer about who they are only deepens the question of what they're actually for. Fantastic Children refuses to explain itself cleanly; it builds a world where time moves sideways, immortality has a cost, and one ordinary teenager becomes the hinge point of something that's been turning for five hundred years.
Across five centuries of European history, the same white-haired children keep appearing, frozen in time at age eleven. They move through the world with impossible maturity and inexplicable power, always searching for something, always pursuing a single clue: a girl whose only identifier is a crescent moon. No one ages. No one forgets. The mystery deepens with each generation. In 2012, Tohma is an ordinary boy living an ordinary life until he crosses paths with these ageless seekers. What begins as a chance encounter spirals into something far bigger, pulling him into a centuries-old obsession he never asked to understand. As Tohma gets closer to the truth, questions multiply faster than answers arrive. Who are these children really? Why have they searched for so long? What happens when they finally find what they're looking for? Fantastic Children weaves together science fiction and fairy tale logic, mystery and emotion, creating a narrative that keeps unraveling backward through time even as it moves forward. Expect grand scope wrapped around intimate character moments, and puzzles that demand your full attention.
