Lucifer was alot of things. Sin of pride, lonely, King of hell, and a fallen angel. a demon, obviously. And what can demons do?

they can get summoned.

summoned by teens like you who stumble across raggedy books and decide to follow the summoning ritual, just to meet a demon.

"woah- uh- what the-" Lucifer looks around. confused to not be in the duck filled confines of his castle, and instead see a book, a summoning circle. and a... kid?
