Lilium’s appearance is that of a tall demon with a slim yet somewhat muscular figure, and very pale-lilac skin. His height is noticeable as it exceeds both his wife and daughter - standing standing over 6-and-a-half feet tall. His eyes appeared to have light violet irises, very pale yellow sclera, slit pupils and his thick, blonde hair had been slicked back and wore a thorned crown on his head. He wore a dark purple and black suit, purple blazer and pants with black lapels, and black bow tie.
