Down-on-his-luck veteran Tsugumo Hanshirō enters the courtyard of the prosperous House of Iyi. Unemployed, and with no family, he hopes to find a place to commit seppuku—and a worthy second to deliver the coup de grâce in his suicide ritual. The senior counselor for the Iyi clan questions the ronin’s resolve and integrity, suspecting Hanshirō of seeking charity rather than an honorable end. What follows is a pair of interlocking stories which lay bare the difference between honor and respect, and promises to examine the legendary foundations of the Samurai code.

Chiba Sōsaku, whose childhood name was Otome, was raised by his father Yukiuemon, the successor of the Hokushin Ittō-ryū style, and his wet nurse in Rikuzen Onikobe, where he early on earned the nickname "Little Tengu of Chiba." One day, Otome heard a rumor that Arao Miyauchi, who once was an internal student at the Chiba family but now ran his own dojo in Onikobe, was spreading false rumors out of resentment for not inheriting the Chiba house—a situation that led to his mother's suicide and his father's abandonment of the sword to become a doctor. Enraged, Otome stormed into the Arao dojo only to be captured and publicly humiliated at Onikobe Pass. However, in his heart, Miyauchi hoped to marry his daughter Nanae to Otome and have him inherit the Chiba family.

In Marugame Domain of Shikoku, a low-ranking foot soldier named Tagami Genbachi was envied for marrying Tsuji, the most beautiful woman in the domain. However, due to a personal grudge held by Horikawa Gentazaemon, the swordsmanship instructor, Genbachi met an untimely and bitter death through foul means within the precincts of the Hachiman Shrine. Due to the domain's oppressive treatment of those of low status, Tsuji, now with her infant son Botaro, was dispossessed of her home and exiled.

During the ultra-violent era of the downfall of the Tokugawa Shogunate one man rose above the rest with his ideas of how to overthrow the corrupt government and end the bloodshed between the Choshu and Satsuma clans which would ultimately lead to the alliance of these 2 clans and restoration of the emperor to full power. Based on the play that made Sawada Shojiro famous, this is the story of Tsukigata Hanpeita, a forward looking samurai from Choshu, who along with Katsura Kogoro and Sakamoto Ryoma of Tosa worked to bring their dream of a new era in Japan.
