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.

Togame and Shichika travel to the Shinou Issou School to take on its master, Zanki Kiguchi, for possession of Outou Nokogiri. Being a sword instructor, Zanki is bothered by Shichika's style and refuses to fight him until he receives training at swordsmanship. She offers to instruct him and the two begin a ten day training regimen, much to Togame's chagrin. Meanwhile, the Maniwa Corps are able to retrieve the most poisonous blade of all, Dokutou Mekki. Before they can leave with the sword, Emonzaemon arrives with the intention of assassinating Houou. Penguin and Houou flee while Oshidori stays behind, only to be gunned down with Entou Jyuu after putting on an impressive battle.
