29-sai Dokushin Chuuken Boukensha no Nichijou Ep 1

Hajime Shinonome is a 29-year-old seasoned adventurer who has long stepped away from the glory of youthful ambition, instead content with his steady life in Komai Village. During a dungeon expedition, he rescues a young girl named Rirui, who was abandoned and nearly consumed by a slime. Driven by memories of a similarly unforgiving past, Hajime takes her under his care. But as Rirui begins to reveal unexpected abilities while adapting to the rhythm of village life, Hajime finds that their shared existence may prove to be more consequential than any other quest he has ever attempted.[Written by MAL Rewrite]
