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.

Hakuhei Sabi challenges Shichika to a duel for possession of the Hari Sword and the rest of Shikizaki Kiki's Blades. Meanwhile, the Maniwa Ninja's Insect Squad attempt to kidnap Nanami and use her as a hostage against her brother. However, the Insect Squad soon discover that although Shichika is the head of the No Sword School, Nanami is far superior to her brother in combat and it doesn't take her long to kill all three of the Ninja sent after her.
