Midorima's life was full of good luck and good days. As a well-known surgeon, he's saved many people and helped quite a few lives. Misfortune and failure aren't even apart of his vocabulary. However, all that changes one day and Midorima's life comes crashing down. The only thing that could possibly have the power to save him would be his guardian angel. Too bad he doesn't have a guardian angel, but a guardian demon, named Takao. So, can Takao save Midorima from the forces against him, or will Takao be dragged down along with Midorima?
