Muzan Kibutsuji

Muzan appears to be a man in his twenties. He has wavy black hair and red eyes. He does not forgive the Moons for incompetence and failure, but will praise them for successfully completing a mission. Kibutsuji does not take his enemies seriously. Muzan also does not like being questioned or ordered around. He has narcissistic tendencies. His inflated ego and delusional sense of self-worth is so great that he cannot stand being mocked or corrected, believing that others only exist to serve him. This also means that he rarely takes any opponent or threat seriously. He has brutally murdered a pair of drunken men simply for being rude to him, and killed their companion when she did nothing, all while proclaiming his own perfection and superiority over them. Manipulative and cunning, able to blend in normally in human society.
