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.

Mano Reiji, a man who experienced a gruesome incident, is a forensic researcher at the Tokyo Metropolitan Police Department's Investigative Science Research Institute. Under the belief that "appraisal will result in the truth" and with his vast knowledge, Mano approaches cases from a view point that differs from others. On the other hand, Sawaguchi Nonna (Araki Yuko) is a rookie forensic researcher that begins working with the no nonsense Mano. They are forced to work together on a murder case.
