Muzan Kibytsuji

Muzan's appearance is that of a man in his twenties with unnaturally pale skin that can easily be mistaken for unhealthy and sickly. He has curly black hair and sharp, almond-shaped eyes. The pupils are vertical, like a cat's, plum-red in color. Muzan also has sharp blue fingernails. In his first appearance, the character was wearing a white hat with a red ribbon and an extravagant outfit: a black tuxedo with embroidery and a white tie over a black shirt and white pants. He also wore black loafers.
