He then spends years using treachery, poetic sensibility, military and political strategy to expand Takeda's realm, advance the claim of Yu's son as the heir, and prepare for an ultimate battle with the forces of Echigo.

Meanwhile, Takezo is observed by Sasaki Kojiro, a brilliant young fighter, confident he can dethrone Takezo. After leaving Kyoto in triumph, Takezo declares his love for Otsu, but in a way that dishonors her and shames him. Once again, he leaves alone.

In the Edo period, a nameless ronin accepts an assignment to go to a mountain pass and wait. Near the pass he stops at an inn where a collection of characters gather, including a gang set on stealing shogunate gold that's soon to come over the pass.

He's reluctant to murder innocent people; then he learns that the gold shipment is a trap and he's part of a double cross. How he sorts through these divided loyalties tests of his samurai honor, and perhaps of his love for a woman.
