An Adventurer's Daily Grind at Age 29

Hajime Shinonome spent his childhood in a poor district, desperately seeking strength just to stay alive. Now, he enjoys a peaceful and comfortable life as a village‑affiliated adventurer in Komai.

One day, while on a quest inside a dungeon, he comes across a young girl who is about to be devoured by the weakest of monsters, a slime.

Her name is Rirui, and she had ventured into the dungeon alone in order to survive.
Unable to abandon a child who was cast aside by her parents and has nowhere to go, Hajime brings her back to the village... and the two begin living together?!
