The series follows this quick-change detective as she uses costumes like Chinese dresses and maid outfits to go undercover and solve mysteries. The setting is contemporary Japan, where the investigator operates within a framework of comedic and slice-of-life detective work. Three individuals, two men and one woman, work together as a team to cut through complex cases with speed and style.

The story is structured around episodic investigations, with each arc presenting a new case that requires the protagonist to adopt a specific disguise and persona to get close to suspects or infiltrate locations.
