One year after the Chaos Arena's fall, Asagi and Sakura arrive on the forsaken streets of Tokyo Kingdom, a vast man-made island adrift in Tokyo Bay. The sole link to the mainland is a long bridge that has become a conduit for hellish beings, drawing in criminals and outcasts who have reshaped the floating city into a treacherous haven. Amid the abandoned blocks, a central business district maintains fragile order alongside notorious pleasure quarters. Survival here demands vigilance, as only the strong endure and unwise alliances can prove fatal.
