In Part I we see the young would-be swordsman setting out to achieve greatness in war, achieving nothing because fighting on the losing side, & then beginning his long period of wandering & training, with the goal always in mind of his duel with Kojiro. Part II builds toward that great duel on Ganryu Island, with considerable focus on Musashi's planning & forethought as to how to gain an advantage.
1864. Samurai Shinbei is sent in a secret mission to Ezo, in the North of Japan, to stop riots of villagers commanded by Jirozaemon. A Russian count's daughter, the village leader's daughter and a secret treasure add up to the adventure.
