Asmodeus

Appearance
He was a handsome young man. His white skin like a marble was a sharp contrast with his black hair and the horns of a lewd goat.

Description
The King of Lust was both a child and an adult. He was both he and she, and a pure virgin as well as a madman addicted to sex. As someone who could freely choose men, women, and children, his look didn't matter to him at all.
