Daimon Michiko is a 37-year-old freelance surgeon who is part of a questionable “doctor placement service” that has her wandering from hospital to hospital. The harsh environment at the hospitals led many doctors to retire from their positions, forcing hospitals to make use of the said program to fill the empty spots, at least temporarily. However, Michiko doesn’t look like a doctor at all with her flashy clothes and eccentric attitude. In the first episode, she raises objections to a certain operation which is planned to be done by the head of a hospital who hasn’t performed an operation for a very long time. This causes Michiko to incur odium at the hospital. However, everyone becomes frozen when Michiko points out the outdated skills of the director. She also holds scrupulous compliance when it comes to her working hours, never does any unnecessary chores that don’t require a medical license and couldn’t care less about the power struggles within the hospitals. Nobody knows how she acquired such a top-level skill that allows her to claim exorbitant sums as a reward, but her private life is an even greater mystery to everyone around her. Tanaka is a rookie surgeon, Uchida is an anesthetist, Kishibe is the head of the placement service, and Ito is the head of the surgical department of this institution.
