City Hunter takes place in 1980s Tokyo and follows the exploits of private detective Ryo Saeba, who accepts work-for-hire jobs that require his particular set of skills, namely, he’s an expert marksman, a skilled combatant, and a talented driver. He’s also a womanizer, despite his lack of luck with the women of Tokyo, and that usually gets him into trouble, especially with his assistant, Kaori Makimura, who resorts to whacking him with a hammer when he gets carried away.
The pair work as “sweepers,” and though normally they butt heads with criminals of all sorts, sometimes they go against other sweepers or people from Ryo’s mysterious past as a guerilla fighter.
