Based on the original manga series by Kusamizu Bin (story) and Megumi Saburo, the drama follows the story of Kishi Keiichitaro, a dashingly handsome pathologist who is intensely eccentric and brutally honest, but also holds one of the most brilliant minds. A pathologist is a physician whose job is to determine a diagnosis of disease or cause of death based on an assortment of data, including a patient's tissue, bodily fluids, organ samples, blood, etc.
