In a world where magic and technology was supposed to make the lives of all the people easier and productive, the opposite happened, the people became addicted to magic that they fought and killed each other just to gain new powers, and because of this they become corrupted and they mutated their appearance, they were called Aldakor, and they somehow lose their sanity. And because of this, the government sent NAILS and their Capt. John Kross, a guy with a cyborg's arm, and despised by other military personnel because of his arrogant and indifferent personality. He was tasked to roam the world and eliminate the Aldakors, as his family was brutally killed and eaten by Aldakors in the past.
