A Locksmith in Another World

Kii Jinroku, a freelance locksmith working in Japan, was recruited by a strange old man and a fox-eared girl to come to another world. His job was to pick locks at the thieves' guild. Using the skills and tools he honed under a master craftsman, he opens all kinds of locks in the other world. Treasure chests, hidden doors, prison cells—there are surprisingly many locks in this other world. What will he do as a master lockpick in this strange new world? Can he return to Japan? What? He can return? And freely at that? Well then, let's just enjoy it for now—and so he works freely and at his own pace. A hero? A demon king? They exist, but he doesn't care about them. Because he's a locksmith, after all. But he can't avoid the troublesome matters that come his way either… A single locksmith might change the world… or maybe not?
