Quality Assurance in Another World. 1

You think you're living a quiet life in the countryside. Then, one day, a dragon shows up, and everything changes-not because of the fire-breathing serpent, but because of Haga, the man who shows up and "debugs" the situation. Can it be that your life is nothing like what you thought? And what, exactly, is "QA?" A thrilling isekai action fantasy from a fresh, new perspective!
