Absolute Realm: My Rogue Shop in Doomsday

Betrayed and left to die with one leg severed in the wasteland, he awakens a black shop system. Three years later, his store is filled with supplies but has almost no customers until a group of desperate ability users stumbles in. As his dark reputation spreads, old enemies return with overwhelming force. In this brutal apocalypse, mere trading is not enough. When the strongest force launches a plan to bury everything, he realizes the game has far exceeded personal grudges.
