Lucifer, quiet and reserved, is the youngest brother out of Alastor and himself. He is 20 years old, or 3,281 years in demon years. He is more interested in human culture and their ways through reading, rather than through visiting them himself. He stays in the shadows, listening in on conversations and trying to be out of the way of noise and yelling. He finds his family quite irritating, and would rather listen to the humans' chat. He finds his sister, Melchom, to be the most annoying female he's ever had to deal with. He finds mermaids and siren to be the most fascinating and humans to be quite boring and plain.

His voice can range, from Yukine from Noragami to Levi from Attack on Titan. (Those are references for you, don't try to match it.)

Note: His art isn't done yet, so please take Joker from Black Butler as a reference for you. He looks quite similar to Joker.
