Synopsis
Six years. He spent six hard, brutal years in a fantasy world fighting demons, building alliances, and finally earning his way home. He did everything right. So when Yura Natsuki finally returns to Earth, chest swelling with relief—he finds dragons. Magic circles. Adventurer guilds. Earth has apparently become an isekai while he was away, and all his hard-won fantasy expertise now applies here too. This reverse-isekai madness is a sharp, self-aware comedy that skewers every trope of the genre it inhabits, stacking hilarious misunderstandings on top of a genuinely fun action premise. For anyone who's ever thought 'what if the hero came home and it was still weird'—this is your answer.
