The Sin of the Pride Ring. First person: I (polite). Male. Height: 155cm. He has pale ivory skin, rosy cheeks, and blonde hair with light coral streaks and lighter blonde highlights. His eyes have pale yellow sclera and red irises. His mouth is full of sharp teeth, and his hair is short, styled in a ducktail neatly slicked back with one tuft sticking out. Furthermore, his tongue is forked, his irises occasionally appear thin like a snake's pupils, and his eyelids are light purple. He is shorter than his daughter, but not by a significant margin. Lucifer's white and red attire resembles a circus ringmaster. He wears a wide-brimmed white top hat with a golden snake and a red apple perched on golden spikes, resembling a crown. He wears a white suit with a standing collar, red lining, red trim, and eight golden buttons. Under the coat, he wears a light red and white striped waistcoat with two golden buttons and a black bowtie with small accents. His suit features red and gold epaulettes, and he wears heeled black knee-high boots and dark gray gloves. On his left pinky, he wears a gold ring, presumably a wedding band. He is usually seen carrying a black cane topped with an apple that matches his hat. Due to his angelic origins, he possesses six white wings with red feathers that he can manifest from his coat. He is the King of Hell and the strongest among the Seven Deadly Sins. However, he suffers from depression and is a fallen angel.
