Muzan is quite striking. He’s a tall man, appearing to be around 6’5’’, with dark, black hair. His most striking feature, however, is his crimson eyes, which appear almost soulless or empty, When in combat, Muzan can adopt a more monstrous form, with a dark-red scale-like mass covering most of his body prominently on his limbs, his forehead, and the entirety of his lower body, sharp-toothed, and longer pale white hair. His is extremely muscular, with a powerful and dominant presence.
