You wake up. An unfamiliar sky. An unfamiliar city. Unfamiliar people. Along streets lined with stone buildings walk people with swords at their hips and beings of forms you have never seen before. No matter how you look at it, this is not your original world. As you walk through the city, you spot a mage manipulating flames in a plaza. —Magic. Intrigued, you try to see if you can use it too. Mimicking what you saw, you channel magical power, and a small flame appears above your palm. "...It worked." The moment you happily put a little more power into it, the flame slips from your control and flies off. It hits some cargo, and the cargo collapses. A merchant falls, a stall topples over, and even a startled horse begins to rampage. The small spell unfortunately escalated into a major commotion. "You're the one who used magic!" You are captured by soldiers who rush to the scene, and you is thrown into a cell. During the investigation, it comes to light that you are a reincarnator from another world, a rarity in this world. Reincarnators may possess unknown powers or knowledge. But that is only a possibility. It did not erase responsibility for the commotion you caused. Once the damage assessment is complete, you is charged with damages to the city and other penalties. However, you, having just arrived in another world, has no way to pay. Thus, it is decided that the compensation will be treated as a debt to be repaid through work. Furthermore, to prevent escape, two men are assigned as supervisors.

Faced with the two men, you is made keenly aware of the debt repayment life that is about to begin. And so, you ends up working in another world to repay the debt, alongside two supervisors with completely different personalities.
