Togame travels to a mysterious island to track down the current head of the Kyotouryuu fighting style to assist her in locating the Klesha Bringers, twelve weapons of extraordinary power.
|Tasked by the Shogunate to retrieve the Klesha Bringers, Togame travels to a remote island to find the current head of the Kyotouryuu fighting style. When she gets there, she meets Shichika Yasuri, the current head of the art form. After a brief test of his skill, Togame travels back to his home and is introduced to his sister, Nanami Yasuri. Here, Togame explains her reasons for coming to the island and asks for Shichika's assistance in retrieving the weapons. Because of past instances of betrayal by ninjas who kept the swords for profit and a swordsman who refused to turn over his weapon out of pride as a swordsman, Togame tells Shichika that he is the ideal candidate to help due to the facts that he does not care about worldly possessions and that as a Kyotouryuu practitioner, he has no interest in swords. In exchange for his help, she tells Shichika that she will allow him to fall in love with her.|
|After announcing this, the house is attacked by Koumori Maniwa, the ninja who betrayed Togame. Shichika rushes off and the two engage each other in combat. When the battle comes to a stalemate, Koumori retreats into the woods, taking Togame with him. Using his ability to change his shape, his transforms into Togame and heads off to find Shichika in order to kill him. However, his plan backfires when Shichika, who is terrible at recognizing faces, blindly attacks Koumori-Togame. Injured and shocked at Shichika's stupidity, Koumori tries to turn Shichika against Togame by telling him her true past: Togame is the daughter of the man Shichika's father was ordered to kill (and killed in front of her no less) and that her mission is solely to collect the weapons on her own behest so that her ranking in the military and government will increase.|
Koumori's plotting has an opposite effect as Shichika feels sorry for her after hearing the tale and decides to assist her. Koumori attacks Shichika by transforming into him to gain his superior strength but makes a critical mistake when he tries to wield Zettou Kanna. It's not a case that Kyotouryuu users don't wield swords, it's that they can't wield them, which causes Koumori to drop his weapon in the middle of an attack and Shichika counters him with a brutal series of attacks, ending the battle.
After finding Togame, the two head back towards Shichika's home where Nanami gives them her blessing and their quest begins.
