29-sai Dokushin Chuuken Boukensha no Nichijou

Hajime Shinonome grew up in the slums and learned early that survival requires strength. At twenty-nine, he is a seasoned adventurer living in Komai Village, finally content with a quiet routine of guild jobs and no grand heroic ambitions.

That routine changes when he finds a young girl named Rirui inside a dungeon after her parents abandoned her and she entered alone to survive. Unable to leave her to a fate that resembles his own past, Hajime brings her back to the village and takes responsibility for her. As Rirui begins showing unexpected abilities, he discovers that raising a child may be a harder—and more important—adventure than any dungeon he has entered.
