Strategist Togame arrives on an island to locate the exiled head of the Yasuri family. She meets the current head, Yasuri Shichika, and his sister Nanami. Togame reveals her quest to find the twelve most powerful swords in Japan, crafted by Shikizaki Kiki, and requests Shichika's assistance. Shichika initially refuses, having no reason to help. Togame then commands him to fall in love with her, providing the necessary motivation for his cooperation. Their interaction is interrupted by an attack from a ninja of the Maniwa Ninja Corps wielding one of the twelve swords, Zettou Kanna. Shichika defeats the attacker and agrees to aid Togame. The pair then begins their journey across Japan to locate the remaining blades.
