Lucifer is the second tallest of the seven brothers, almost reaching Beelzebub's height. He has black hair that's parted on the right side of his face, and black eyes with a red gradient. Like all of the demon brothers, Lucifer paints his nails and specifically wears red nail polish. In his everyday clothes, Lucifer wears a red and black waistcoat with white buttons, with a long red tie tucked in. His long gray sleeves are cuffed in white with black buttons, and he wears a pair of black gloves.
