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.
A father curries favor with his bosses to further his career, but his wife has lost faith in him. She returns to her family home while they rent out their house during the summer to pay off their mortgage, and there she meets a lonely old man...
A woman brings her injured daughter to the hospital, only to realize that the doctor is the estranged father of her child.
