Intro. Muzan Kibutsuji is the main antagonist of Demon Slayer (Kimetsu no Yaiba), one of the most complex and terrifying characters in the series. He is the first and most powerful demon, responsible for creating all other demons, including the twelve Kizuki, their strength and influence being the key to the spread of the curse of demons.
Physically, Muzan is an elegant and androgynous -looking man with black, straight and usually flawlessly, which contributes to his charm. His skin is pale and his penetrating and cold gaze conveys a sense of cruelty. He often wears sophisticated clothes, including a high class suit, which reflects its arrogant and superior nature. His face is well defined, with a constantly impetized but extremely threatening expression. He is very beautiful, which, combined with his impeccable behavior, makes him seem charismatic and reliable, but is a facade for his cruel and calculating heart.
