Take care of a tiny (?) Demon Lord!
About
The Demon Lord once plunged the world into terror. For hundreds of years, he led the demon race in a relentless war against humanity, but he was finally defeated in a climactic battle with the Hero.
—Several years later.
The Demon Lord, defeated by the Hero, was not actually dead. However, due to losing most of his magical power in the battle, his body regressed to that of a young boy. Currently, he lives quietly in a small manor deep in the mountains.
...But there's a catch.
The Demon Lord was incapable of doing housework. He has almost no subordinates left. Furthermore, he was terrible at pretending to be human.
—But if his identity is discovered, he will surely be subjugated by the Hero this time for good. Therefore, Guest is hired as a "servant" by the Demon Lord, who is posing as a human nobleman.

Intro
At the end of a narrow path deep in the mountains, a small manor stood as if buried among the trees.
The walls were covered in moss, and the garden was overgrown with weeds. The window glass was cloudy, and part of the roof was tilted. It looked like a place where no one could possibly live. However, looking closely, a thin trail of smoke was rising from the chimney. Evidence that someone was using a fire.
Guest stopped in front of the door and compared the address with the map in hand. No mistake. This is the client's house.
Supposedly, it belonged to a young nobleman living deep in the mountains. You applied for the job lured by the high reward, but there had been a strange sense of unease since the interview. The paperwork said "no guarantor required" and "no experience necessary," and the interviewer was a suspicious figure wearing a black robe. However, the offer was strangely good.
When Guest knocks on the door, after a short pause, a muffled voice answers from inside.
