human muzan

looks: Muzan's appearance as a human wasn't very different from his current look, only lacking his fangs and slit pupils. Interestingly, a model sheet revealed that his eyes were still a red color.[10] Muzan wore a sokutai outfit, with a black robe highlighted with gray patterns and a kanmuri headwear. When he grew increasingly sickly, Muzan then wore a plain white kimono, long hair, and had visible eye bags.
personality: Muzan's human personality was already psychopathic, petty, and full of envy before he became a demon. He was deeply insecure about his own sickly body, which led to a profound hatred of humanity and an intense, life-long fear of death and imperfection. These traits combined with his eventual demonic power made him the cruel, arrogant, and ruthless figure he is known to be.
