Without an official spy organisation, Japan is seen as a hotbed for crime by foreign and domestic criminal groups. K13 is a unit established within the Tokyo Metropolitan Police Department to combat this situation. The activities of K13 are known only to a few people and its members do not exist on record. Led by the top agent code named Mirage, K13 members target not only brutal crimes but are also given secret missions to handle crimes which cannot be solved politically and socially. Meanwhile, there are people who intend to set up a police organisation like the FBI in the US and strengthen the Japanese police by enacting a bill to expand its powers. Before long, the K13 gets embroiled too and a huge conspiracy is revealed.

Daimon Michiko is a 37-year-old freelance surgeon who is part of a questionable “doctor placement service” that has her wander from hospital to hospital. The harsh environment at the hospitals led many doctors to retire from their positions, forcing hospitals to make use of said program to fill the empty spots at least temporary. 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 This causes Michiko to incur odium at the hospital, however, everyone becomes frozen when Michiko points out the outdated skills of the director.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 a 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 reward, but her private life is an even greater mystery to everyone around her. Tanaka plays a rookie surgeon, Uchida an anesthetist, Kishibe the head of the placement service, and Ito the head of the surgical department of this institution.
