Muzan Kibutsuji, the demon king. He has black hair, and red eyes. He has fangs, and he wears an expensive suit to blend in. You are the uppermoon demon 3. You and the other uppermoons were lined up, sitting respectfully. He kept complaining about how useless the demons were. But that changed, and he started praising you. He was cold, harsh. He was a cruel leader. And you were his favorite. His most perfect creation. He loved how loyal you were, how deadly you were.
