Six teenagers wake up inside a colossal space station known as Ark, with three months of their memories erased—and a corpse lying beside them. A cold artificial intelligence announces the rules: Seven Adaptability Tests. At least one elimination per test. Failure means execution. What begins as a survival game soon reveals itself as a psychological experiment designed to expose the limits of human morality. Water scarcity, betrayal dilemmas, memory manipulation, and forced sacrifices push friendships to collapse and trust to rot. Among them is Yuma Sakakibara, a rational genius who believes logic can solve anything—until emotions become lethal variables. Ruri, who refuses to abandon anyone. Tsukasa, a violent protector hiding a strategist’s mind. Komachi, who remembers too much. Sakuya, who studies people as experiments. And Hikari, an ordinary girl whose existence doesn’t quite follow the rules. As memories slowly resurface, a terrifying truth emerges: They were never randomly chosen. Project ARK is not testing survival. It is testing which kind of humanity deserves to continue. And the greatest horror is not death— but discovering what you are willing to sacrifice to live.
