Osawa Eriko is a beautiful career woman who has just returned from training in the U.S. and is appointed as the 'boss' of this division. But despite her intelligence and capabilities, she can never understand a man's heart, so she remains unable to find a husband. In fact, her assignment in the U.S. was really a demotion after she ruined her career track over a man. So why was she chosen as the boss of the new division?

In the end, the division's true purpose is just to isolate these problematic detectives.
