What (who) is peace-maker - definition

Peacemaker Kurogane (Japanese: PEACE MAKER鐵, Hepburn: Pīsu Meikā Kurogane) is a Japanese manga series written and illustrated created by Nanae Chrono. It is unrelated to the Peace Maker manga by Ryōji Minagawa. The story begins in 19th century Japan before the Meiji Restoration, a chain of events that led to enormous changes in Japan's political and social structure while the seeds of the revolution are being planted. The story follows the boy protagonist, Tetsunosuke Ichimura, who joins the Shinsengumi (initially as Toshizō Hijikata's page) while seeking strength to avenge his parents' death at the hands of a Chōshū rebel.

It is a sequel to Shinsengumi Imon Peace Maker (新撰組異聞PEACE MAKER, Shinsengumi Imon Pīsu Meikā), which was published by Enix in the magazine Monthly Shōnen Gangan. Shinsengumi Imon Peace Maker was licensed in North America by Tokyopop.
