Crying Freeman (クライング フリーマン, Kuraingu Furīman) is a Japanese manga series written by Kazuo Koike and illustrated by Ryoichi Ikegami. Crying Freeman follows a Japanese assassin hypnotized and trained by the Chinese mafia (called the "108 Dragons") to serve as its agent and covered in a vast and complex dragon tattoo. A quiet but complicated killer, Freeman reflexively sheds tears after every killing as a sign of regret.
