Isazo (Ichikawa Raizo), commonly known as the "Ripper," is a living legend in the world of Yakuza. He is known for his swordsmanship and bravery, but also for his politeness and gambling talent. One late autumn, at an inn near Fukushima, Isazo made friends with a little boy whose mother was his old love Yoshino. Due to their class differences, he was unable to marry Yoshino.
