住んでる場所が田舎すぎて、ダンジョン探索者が俺一人なんだが？

"Please, just give me a day off..." Souma Hajime, the one and only dungeon explorer in the backwater town of Mifune, is forced to handle all the work by himself due to his guild's severe lack of manpower. In his private life, he is infamous as an annoying “backseat gamer” fan, sending high-value Super Chats to his favorite streamer along with unsolicited, hardcore advice. But his true identity is that of a genuine A-Rank Explorer, standing among the top 0.1% in the nation! This is the story of an overworked, seemingly unremarkable young man who, despite being stuck in a rural town, is about to make his name known across the globe.
