Crusading doctors are certainly nothing new in the J medical staple -- doctors who are renegades, confrontational and do their best (or worst) to buck the system that they are forced to work in. Kosuke Sagara, a surgeon specializing in gastroenterology, is no different in that respect. However, aside from being the ultimate surgeon, he is a brilliant strategist bordering occasionally on the Machiavellian. Underneath that cloak of smiling affability that wanders around Dougami General Hospital, is a ruthless manipulator whose chief goal is to transform a mediocre hospital into a world class facility. Fortunately, for the hospital and its inmates, this meddling doctor is on the side of the angels and his clarion cry is "everything is for the sake of the patients".
