Do you know what it’s like to be a powerless NPC unit? I found out when I suddenly woke up in the body of an ordinary skeleton worker! The clinking of pickaxes against stone, the Network’s commands in my head, and a mysterious Master, whose property I am. A fun situation? Not really! And it’ll get even more fun when, with this very pickaxe, I level up on omnipresent monsters that have wandered into adventurers from the nearest town—and then evolve! And who knows, maybe I’ll even reach the so-called Master… but first I’d better find a pickaxe that’s tougher!
