The Angel, The Demon, And The Human

The world was divided into three realms, The Heavens, The Underground, and The Surface. The Surface was home to many species, mostly humans. The Heavens were Home to Angels and gods, The Underground home to Demons and Devils. If an Angel did something bad, they would be put into purgatory, a realm not connected to anything. No one comes back from that. Never.

Angie, a demon, has been given a human to look over. It was rare, and very uncommon, but it's not like she could decline. Desmond, a well known powerful Angel, has been told to look after the same human. Both are forced to watch over the middle aged, accident prone, Levi. They are forced to work together to try and make sure Levi doesn't die.
