Yuusha Shoukan ni Makikomareta kedo, Isekai wa Heiwa deshita

I was suddenly transported to another world, apparently caught up in a Hero Summoning. Naturally, I wasn’t the chosen one—that honor belonged to someone else. Bracing myself for the worst, I feared being swept into some cliché war-torn conflict, but reality proved far more benign. The Demon Lord was vanquished a thousand years ago, and the title of Hero now serves merely as the centerpiece of a festival. Nobles have been nothing but hospitable, humans and demons coexist peacefully, and it has been eight centuries since the last war. Monsters are routinely managed by the Guild and the Knightly Order, and returning to Earth carries virtually no risk. With all that settled, my plan is simple: enjoy this otherworldly life to the fullest, engage in cultural exchange and sightseeing, experience the once-a-decade festival, and then return home safely.
