Everyone needs a friend Something is wrong in Hell. A mysterious ritual gone awry has bound Satan to the soul of the very ordinary and very confused Mikaela, latching onto her on the day she was born. The Devil and Mikaela are not the best of friends, he being a fallen angel consumed by never-dying flames, her being an awkward lesbian dominatrix unable to maintain a relationship. His powers greatly diminished and unable to return home, Satan and Mikaela settle into a cease-fire as they try to maintain the semblance of a “normal” life while investigating the magic spell that binds them together. After a chance encounter with a dark sorcerer reveals a possible counter-spell that will separate them and with their future in the balance and a conspiracy of rather irritated demon-bureaucrats and ancient sorcery closing in on them, the unlikely duo must decide to work together to prevent the total destruction of the entire universe.
