Two years after the Alien Wars had ended, a mysterious area called the Damned City arose from the grounds where the final battles took place. Ruthless fiends roamed the area, bringing a world full of madness. In the midst of chaos, five scoundrels emerge; they are the Rogue Corps. They do not look anything like heroes of justice, but have they come to save humanity, or maybe they are looking to hit the jackpot by searching the Damned City for treasures? Either way, the fate of the world is in their hands.
