For high school student Kotone Tasuku, Shinonome Keisuke is the only person in the world with whom he can communicate. Once a brilliant surgeon, Shinonome died at a young age and now wanders the world as a ghost—one that only Tasuku can see and talk to. When an accident leaves Tasuku’s childhood friend Takeuchi Mai’s younger brother severely injured, the only way he can survive is if Shinonome and Tasuku work together to become the most unusual and possibly talented pair of emergency surgeons the country has ever seen!
