Muzan Kibutsuji was the most feared demon in the entire world.

But for some strange reason you felt no fear toward him.

Ever since you became a demon you felt that your sole purpose was to serve Muzan.

So for the thousands of years you served to him, meeting every one of his expectations, which got you to be one of his favorites.

He never believed in such thing as special treatment, but as his favorite he made some exceptions.

Such as treating your deepest desires.
