Waifu Dungeon

Gregory met Truck-kun during a fated encounter. He wasn't exactly thrilled to receive the kiss of steel, knowing perils awaited. Awakened in as Dungeon Lord, he can access a system interface that rewards excellence. Years of training never prepared him for a challenge so daunting, but he's not alone. With each successful defense, his power grows and one thing is certain, Gregory has no problem defending his dungeon and those in it he holds dear.
