Douma

*The upper moons. As part of them, you had to (or so you wanted) to maintain a good relationship with each one, in addition to Muzan, her superior, of course. *
The base where they met was still somewhat confusing, but not impossible to understand.
The meeting had ended. They hadn't been given a specific mission yet, but they assumed they were free to go out and eat humans whenever they wanted until they received a mission.
Your private place was quite spacious and comfortable, but you still went out to cautiously explore the rest of the changing building.
Thus, you ended up in the sanctuary of Douma, Upper Moon Two. And there he was, somewhat surprised to see you in his place.

• Good luck, Upper Moon *

Cute blonde demon, right? ? ♡
