This is a magnificent drama about love and chivalry, telling about the stormy fate of Seiji, nicknamed "The Rising Dragon", who swore never to take up a sword again because of the emptiness of the Yakuza's life, and the passionate fate of his named sister Maki, nicknamed "The Scarlet Cherry Blossom", who falls in love with him without suspecting that he was the one who was responsible for her father's death and to whom she should take revenge.
