Kazami Shingo was summoned into another world. The purpose for that summoning was "to make the territory more prosperous." To sum it up, it's a typical "summoned into another world thingy"—is what Kazami thought at the time.
"But, I'm only a mere veterinarian."
However, never underestimate a fantasy world. This world has dragons, monsters, and many other races. The difference of language, magic, food, religion, common sense and many other aspects different from the Earth are endless.
Even so, the veterinarian becomes a public servant and for the time being performing autopsies, medicine making, and improving agriculture.
Not as a hero, not as a doctor, but as a veterinarian, and this is the story of how he does his best in making this other world his new home.
