Shichika and Togame are three months into their search for the 12 Deviant Swords and this time they have arrived at the Sanzu Shrine in order to retrieve the Tsurugi sword. However, in order to obtain it not only must Togame find the original Tsurugi from one thousand identical blades but Shichika must defeat it's master Meisai Tsuruga in a one-on-one duel. To make matters even worse Kuizame Maniwa is also after the Tsurugi sword and soon makes his way to the Shrine.

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.

Having returned to Owari, Togame's home, Togame and Shichika meet with Princess Hitei who tells them about the location of Shikizaki Kiki's workshop and the possible sword hidden there. Following the lead, although distrusting of it, the two go to the location, Lake Fuyou accompanied by Emonzaemon. Upon their arrival, Emonzaemon departs and leaves Togame and Shichika to deal with Bito Kanzashi. While away, Emonzaemon tracks down Umigame Maniwa and reveals that he is the sole remaining heir of the Aioi Corps, a village of ninjas that were wiped out by the Maniwa Corps 170 years ago. Having told him this, he engages Umigame in battle and defeats him completely and effortlessly using Aioi Kenpo.

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.
