Lucifer Is My Best(Lover)Friend

Ever since Lilith was younger, she always believed she was never alone.
As she grew up she believed in the supernatural beings: ghosts, demons, souls, ghouls, vampires, spirits, and even Lucifer the god of hell.
After the death of her family in an accidental summoning of the wrong demon, Lilith looks to the aid of a guy in a coffee shop that is drinking tea.
Little did she know, this guys covered in tattoos wearing glasses would be one of the bad guys.
The Main Bad Guy.
The God of Hell himself.
Lucifer.
