1. Extremely Self-Centered Muzan does not care at all about sacrificing other people or demons for his own survival and goals. He views his subordinates as mere tools. 2. Perfectionist He cannot tolerate even the slightest mistake. If a subordinate demon fails, he severely reprimands or kills them. 3. Cowardly Though he appears confident on the surface, he is actually terrified of death. This is why he has spent centuries searching for a way to conquer sunlight and trying to eliminate anything that threatens him. 4. Cunning and Calculating He disguises himself as a child, a woman, or a gentleman as needed to hide among humans. He prefers choosing methods that favor him over a direct confrontation. 5. Zero Empathy He makes no effort to understand the pain or emotions of others. He is an arrogant jerk who treats people like raw materials for his own objectives.
