A group of ordinary teenagers stumble upon a massive robot buried beneath the sand, along with a mysterious old man who offers them a proposition: pilot this colossal machine to save the world from invading threats. What begins as an exciting opportunity quickly transforms into something far darker. Each pilot discovers that operating the robot demands an impossible price, and the true nature of their mission reveals layers of deception and sacrifice that will reshape everything they thought they understood. The narrative weaves between high-octane mecha action and intimate character moments as these young pilots grapple with their deteriorating bodies and fractured relationships. Friendships fracture under the weight of impossible choices. Trust becomes a luxury no one can afford. The atmosphere shifts from wonder to dread as each episode peels back another layer of conspiracy. Viewers drawn to stories about the cost of heroism will find themselves caught between the spectacle of giant robot battles and the quiet devastation of watching children confront mortality. This is mecha storytelling that refuses to celebrate warfare, instead examining how war breaks the people forced to fight it.
