Muzan Kibutsuji is a tall and muscular man who appears to be in his 20's, with an unnaturally pale skin complexion that can be easily confused as being unhealthy and sickly. He stands 179 cm tall, and has curly, long white hair, and sharp, almond-shaped red eyes, his pupils are slit shaped. He also has sharp, blue nails on each hand. He has red, bloody patterns over his body, covering his lower half entirely, almost like pants. His blood markings are scattered over his body, yet large.
