The City Hunter franchise follows the exploits of Ryo Saeba, who works as a "sweeper" (He "sweeps" crime off the streets) and Kaori Makimura, a tomboyish girl who deals primarily with the business side of things. The City Hunter team is an underground group available for hire for missions like protection and private investigation. They primarily take on jobs involving beautiful women who contact the team by writing the letters XYZ on a blackboard at Shinjuku Station.
