Hana no Kyoudai

Kayama Ichinoshin (Raizo Ichikawa) has been traveling for ten years in search of revenge for his father. One day, Ichinoshin reunites with his younger brother Shinjiro (Yukio Hashi), who has completely changed. Shinjiro abandoned the quiet samurai life and began to lead a Yakuza lifestyle. The older brother is angry at the younger one for his depravity, and the younger one laughs at him for being tied to old-fashioned traditions. As a result, they quarrel. Ichinoshin hears that the person he has to take revenge on has become a Yakuza, and in order to get a hint, he takes care of the Otsu family, to which Shinjiro owes, but later discovers that the boss of Otsu Kanemon is the one he is looking for.
