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

Shichika and Togame are now five months into their quest and have just arrived in Satsuma where they hope to retrieve the Yoroi Sword. However, both the sword (which takes the form of a Western-style suit of armour) and its owner, legendary pirate Kanara Azekura (an expert in defensive combat) will pose a difficult problem for Shichika. Things then become even more complicated than usual when Azekura declares his love for Togame and the fight quickly becomes about much more than simply collecting another Deviant Sword.

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.
