Song of Sado (1961)

Sentaro (Raizo Ichikawa) from Ipponmatsu sets out to commit evil and gain dignity, but his good-natured nature does not allow him to do anything bad. Along the way, Sentaro saves a young woman named Okimi (Yuko Miki) from a bad womanizer and meets a Yakuza named Katsugoro (Yoshie Mizutani). He then visits Katsugoro boss Kanjiro Inariyama (Ganjiro Nakamura II) to train to be a yakuza, but to his surprise discovers that Katsugoro is Kanjiro's only daughter, Okatsu. He also finds out that the young yakuza working in Kanjiro's house is his younger brother Hanji (Yukio Hashi). Then the Shigezo family, who had been annoying Kanjiro for a long time, set fire to his gambling hall!
