Sunderu Basho ga Inaka Sugite, Dungeon Tansakusha ga Ore Hitori Nanda ga?

"Please give me a day off..."

Hajime Souma is the only dungeon explorer in the rural town of Mifune, and thanks to the guild's severe staff shortage, he's stuck handling everything alone in brutal one-man shifts. In his private life, he's the kind of annoying backseater who sends huge superchats full of "serious advice" to his favorite streamer. But in reality, he's a genuine A-Rank explorer who stands among the top 0.1% in the country!

This is the story of an overworked corporate-slave-type boy whose talent goes unnoticed because he operates out in the countryside, as he gradually makes his name known across the world.
