In the fourth installment, Musashi's potentially greatest opponent Kojiro jumps in and out of the story at the oddest and most coincidental moments. As his great love Otsu has succumbed to madness. Musashi then sets off to beat the functionaries of a treacherous clan in an arranged duel. 73 against one. Boastful Kojiro watches, secure in the knowledge that only he is a worthy opponent.
As the Shogun lays dying, seventeen Iga clan ninja are sent to infiltrate the impenetrable fortress where his youngest son is preparing to storm Edo Castle and name himself Shogun by force of arms. They are to either steal the documents that will eventually give him lawful claim to rulership, or they are to assassinate him. But even before they reach the castle walls, they find their every move countered by a ruthless ninja hunter in the employ of the would-be usurper (Konoe), who not only knows their every tactic but knows the exact make-up of their team thanks to his own spies within Edo Castle. As the Iga Ninja fall one by one, the mission's success or complete failure--where failure will result in a bloody war of succession--comes to hinge on a single young and inexperienced ninja (Kotaro).
Three young yakuza, Fujitaro, Matsugoro and Kanjuro, travel the country fighting evil.
