City Hunter

Got a problem? Put down "XYZ" on the message blackboard at the East exit of Shinjuku Station, and wait for City Hunter, a "sweeper," to contact you. Ryo Saeba is an excellent sweeper but a terrible flirt; he and his tomboy partner Kaori get the job done, sometimes making a mess but almost certainly with Ryo getting "mokkori" (a boner) for every beautiful client. With 46 million books sold worldwide, it is an action series with an undying appeal. This is Tsukasa Hojo's second series following "Cat's ♥ Eye."
