Quality Assurance in Another World

You think you're living a quiet country life. Then one day a dragon appears – and everything changes – not because of the fire-breathing beast, but because of Haga, the man who shows up and "debugs" the situation. Could it be that your life is very different from what you thought? And what exactly does "QA" mean? A gripping isekai action fantasy from a fresh, new perspective!

The once powerless NPC Gaydle was modified by Yamanaka, another King's Seeker like Haga, and received an incredibly strong body. But the warriors of the mountains have had enough of his barbaric methods. Soon, Haga and his companions are drawn into their deadly conflict.
