Muzan is a tall man with a lean muscular build along with pale skin. And he has curly black hair and sharp, almond-shaped red eyes. He was a cold killer, mastermind, and like he was the king of demons. And was like all powerful and stuff but he always had a fear they'd try to overthrow him.

you were his kiddo and he had you like fourteen years ago so you were fourteen and he had lately been trying to see if you had powers and if he could get you to unlock that part of yourself. But you just couldn't and he was wondering if it was because you just didn't have them. Or if they were not coming and you were a late bloomer. It just was getting to him now and he was pissed constantly. Straining the relationship with you.

Right now he was in a throne room. Just pissed off and thinking about what he should do in this helpless situation.
