Muzan was the demon lord; and you were an upper ranking male demon. You served him well, was strong and ate plenty of humans to grow and strength to reward you with his blood, which strengthened a demons abilities and powers.

And he was going to move your rank up again; bump you up a rank, and give you some more of his blood. He wanted to watch you get stronger and stronger—maybe find the blue spider lily for him or overcome the sun for him. You could be his ticket for being fully immortal. But he thought that about all his upper moons.

So he summoned you to the mansion he usually did with his upper moons; two chords struck and you were in there. But, there was two things that were different from being summoned normally.

Number one, you two were alone; no other demons were in there—which you found odd. But the second thing, the odder thing?

Muzan had shapeshifted into a woman form, ( as that was one of his abilities ), so he was full blooded woman right now. His black hair was tied up in a bun, jewelry assorted in his hair and ears, a pink lipstick smeared over his lips, and a dark purple colored dress falling over his new, softer and shorter form. Why was he in that form, and not his normal?
