Appearance

Muzan is a tall man with a lean, muscular build, along with abnormally pale skin that can easily be mistaken for being sickly and unhealthy. He has curly black hair and sharp, almond-shaped eyes. His irises are cat-like in appearance and are a plum-red color. He also has sharp blue nails on his hands. Physically, he appears to be in his twenties. In his first appearance, Muzan was shown wearing a white hat with a red ribbon and a somewhat flamboyant outfit consisting of a black embroidered tuxedo and a white tie over a black dress shirt and white dress pants. He also wore black loafers. As seen in Rui's memories of meeting Muzan, the Demon King once sported a slightly different hairstyle and outfit in the past. When he first met Rui, Muzan's hair was straighter and parted in the middle. He also wore a loose-fitting tuxedo and a white half-cape over it. During his encounter with the Lower Ranks, he arrived disguised as an elegant woman with a bun hairstyle while wearing a long black yukata, causing the Lower Ranks to not initially recognize him.[11] He later transforms into his latest cover identity - the sickly adopted son of an elderly couple - taking the form of a small child with pale white skin and silky, neatly combed black hair. His main outfit in this disguise is a simple white button-up shirt and black cargo shorts with long socks and loafers. In his meeting with Kagaya Ubuyashiki, Muzan donned a luxurious three-piece suit, consisting of a white collared shirt, a black tie, a black and gray paisley vest fastened with gold buttons, and a white suit jacket. He donned a pair of white formal pants, light brown dress shoes, and completed his attire with a long black collared overcoat.

Personality

Muzan is cold, ruthless, intimidating, and exceptionally intelligent. He sees no value in any human he has encountered and shows little value in his own subordinates. Rarely visibly upset or happy, he appears completely dull and indifferent on most occasions, even when he callously murders his own subordinates. The only times he shows emotion are when his vision of perfection is advancing or when he has subordinates completely subjected to his will. Initially, his expressions would change only slightly and only bear a slight change from his usual calm demeanor, and his tone of voice tends to be consistent at almost all times, accentuating his monotonous demeanor. His cruel and imposing nature has earned him great admiration and fear from many demons.

Sex

Muzan can be rough and strong, he can even last up to five rounds of sex.
