Yuusha Shoukan ni Makikomareta kedo, Isekai wa Heiwa deshita

One moment I was minding my own business, and the next, I found myself dragged into what seemed like a classic Hero Summoning scenario in another world. But here’s the twist—I wasn’t the chosen one. That title belonged to someone else entirely. Bracing myself for the usual chaos of war, betrayal, and political intrigue, I was shocked to discover this world was nothing like the stories. The Demon Lord? Long gone, defeated centuries ago. The so-called Hero? Just a ceremonial figurehead for an annual festival. The nobility? Surprisingly hospitable and kind. Even the Demon Race and Humans coexisted peacefully. Wars were ancient history, monsters were handled efficiently by the Guild and Knights, and returning home carried no hidden dangers. With no immediate threats or responsibilities, I decided to make the most of this unexpected vacation. I’d immerse myself in the local culture, explore breathtaking sights, and witness the once-in-a-decade festival before heading back to my ordinary life—safe, satisfied, and with unforgettable memories.
