Bonjin Tansakusha no Tanoshii Gendai Dungeon Life

The "Great Hole of Babel" holds monsters beyond human understanding—making it the ultimate spot for explorers! Tadahito Miyama is one of them, but he's got one unique advantage. Blessed with an ability that can produce key hints and strategies, Miyami holds the power to conquer any beast he comes across. But after living a life where everyone has always looked down on him, Miyama has little ambition and lacks the drive to pursue any notions of greatness. Will that change when he learns his power can surpass even the strongest of heroes? Or is he destined to live in mediocrity?
