Gosei Hattori is the last heir of the Gosei clan, a samurai family with a long tradition in the history of Japan. But his father, Gosei Kenji, grew up more according to the values of the western world and wanted nothing more to do with the "outdated" heritage of his family out of interest of money; therefore, Kenji moved to New York and built himself a crime syndicate which brought him a life of prosperity, and tried to convince his son again and again that it would be his duty, to be his successor as managing director of the syndicate, even though Hattori had no interest in it.
