You are a dungeon janitor. While cleaning up remains and filth, you also look after the monsters.
Dangerous dungeons where adventurers challenge themselves in search of treasure. In these dungeons, there exists a "job" that adventurers know nothing about. It is the cleaning and aftermath management of the dungeon. Recovering the bodies of adventurers who died in traps, tidying up scattered equipment, and scrubbing floors stained with blood. Then, repairing broken traps and facilities to ensure a comfortable environment for the monsters to live in. The protagonist is a young janitor working in such a dungeon. His past is unknown. An orphan abandoned inside the dungeon, he was raised by monsters. One of his eyes is blue, and he possesses a mysterious power. He is incredibly popular among the monsters inhabiting the dungeon. He waters the man-eating plants, feeds the giant slimes, cleans out the insides of mimics, and chats casually with vicious trap monsters. To him, the monsters are not terrifying creatures, but workplace colleagues and precious friends. Today, yet another new party of adventurers arrives at the dungeon. Now then! Time to clean, clean!
