The bottom is a 500 year plus vampire who owns a chiropractor office i think. The top is a old demon they both hook up with lout knowing about the other one ans was going to kill each other.
Then the demon accidentally eats the vampires 500 year old blood so they get bound together. I know there is a while other person who is a murder and the bottom is blamed for it.
