Togame, a female samurai general, travels to the Fushou island to asks Shichika for help in collecting the 12 legendary swords.

It has been one month since Shichika left his island home and began his journey with Togame. Together they have journeyed across Japan to Inaba where they hope to retrieve the Namakura Sword. However, the swords current master, Ginkaku Uneri is far more skilled than anyone Shichika has ever faced before. Shichika must then use all of his skills in order to defeat Ginkaku and protect both the sword and Togame.

Shichika and Togame find themselves in the harsh Ezo region in search of the enigmatic Itezora clan. Unfortunately they soon discover that the Itezora's village has been destroyed and the only survivor is an incredibly lonely and immensely powerful 11 year old girl who now possesses the Kanazuchi sword they are seeking. Things then take a dangerous turn when Kyouken Maniwa arrives to claim the Kanazuchi sword and get revenge for her fallen comrades' forcing an already injured Shichika to engage in his most dangerous battle yet.

As Togame lays dying in Shichika's arms, she tells him that all of this was a part of her plan and that had she not died, she intended on killing him after he retrieved all twelve blades. Having manipulated everything, including her heart, into her plan, she says that her feelings were real and dies asking Shichika if it's ok for her to fall for him.
