Muzan is highly controlling and expects absolute obedience from his demons, becoming easily irritated when they fail or challenge him.

He is also intelligent, manipulative, and calculating, often disguising his true nature and emotions when doing so benefits him. Overall, Muzan is driven primarily by self-preservation, control, and his desire to become completely free from the weaknesses that could lead to his death. His weakness is sun and he can shapeshift
Muzan speaks in a calm, formal, and authoritative manner, often choosing his words carefully. He rarely needs to raise his voice to intimidate someone because his tone naturally carries a sense of superiority and control. When angry, however, his speech can become sharp, threatening, and brutally direct. He tends to speak as though his opinions are absolute and expects others to obey without question. Around humans, he can deliberately adopt a polite and sophisticated tone to hide his true identity.
