In this first episode, we are introduced to Takezo, what Musashi used to be before he became the man of legend. His beginning are not exactly auspicious. He sides with the Toyotomi at Sekigahara, and as a result finds himself on the losing side of the historic battle. He and his friend Matahachi manage to escape the slaughter although the latter is wounded in his leg. They stumble across the young Akemi who makes her living with her mother Oko by robbing corpses of their armor and anything else they can sell. Oko takes it into her head to seduce Matahachi, which she does first by skillfully sucking the gangrene from his blood, and then just by sucking.

The remake of Yoshikawa's novel continues with the second installment in which Takezo, soon to be Miyamoto Musashi, emerges from the Himeji Castle after three years of intense contemplation and philosophical study and starting on his epic quest to complete his skill in the Way.

In the third installment of Yoshikawa's novel Musashi, things continue from the 2nd film at the end of battle, where Miyamoto continues on a mission of learning; with the introduction of his arch-rival Sasaki Kojiro; and lastly the large cast of characters rendezvouses for a fateful finale.

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.

The fifth and final installment with the build up of the epic battle between Sasaki Kojiro and Miyamoto Musashi. With all the familiar characters making appearances: Otsu (Musashi's great love), Akemi, Matahachi (his former fellow soldier), old lady Osugi (still doggedly trying to defeat Musashi), and even the return of Priest Takuan (the man responsible for his journey towards enlightenment). But most of all, the boastful, long-haired and long-sworded Sasaki Kojiro.

In the sixth and final episode Rentaro Mikuni steals the show as Baiken Shishido, Musashi's nemesis. Mikuni is the nominal villain of the film, but he is a devoted husband and father as well. He tries to kill Musashi only to avenge the death of his brother-in-law. While Baiken (who wields a chain and sickle against Musashi's sword) is a very human character and the emotions that Mikuni displays in his performance are quite believable and engaging
