Masami Kojomon

In this first film of the Lone Wolf and Cub series, adapted from the manga by Kazuo Koike, we are told the story of the Lone Wolf and Cub's origin. Ogami Itto, the official Shogunate executioner, has been framed for disloyalty to the Shogunate by the Yagyu clan, against whom he now is waging a one-man war, along with his infant son, Daigoro.

Young geisha Koshizu's wish of reuniting with the man, Yukichi, who helped her ten years ago comes true. When she learns of the trouble Yukichi's business is facing, she stands ready to come to his aid, and thus repay a debt that's long overdue.
