The end is not always the end. Nothing is permanent, and even death itself is merely a transition.
This fact holds true for a certain young man who died quite tragically on Earth. Lucky for him, a new life was just around the corner. A world filled with magic, adventure, and oh so many dangers awaited. Everything would be perfect, if it wasn't for the fact that he reincarnated into a homunclus. An artificial life-form said to possess almost zero combat capabilities. An exemplary example of pure breed cannon fodder.
Surviving in a world where dragons roam the skies and monsters stalk the lands, wasn't this a bit too unreasonable?
