Awaji Island Recapture Operation Arc
Kanetatsu continues his paperwork as he haven't finished reviewing this year's taxes, as he prefers this work over combat. Masaki is surprised he brought paperwork to a battle, but tells him to not overdo it. Kanetatsu tells him not to worry, but then wonders if Masaki's house has been underpaying, and Masaki quickly denies it.

Moments later, oni attack and Kanetatsu goes to defeat them. Kanetatsu tells Masaki that he wants proper records of the first deployment battles. Masaki notes he will make everyone hear that he took three or four lesser oni at once, but that annoys Kanetatsu as three or four is vague and records need to be precise. Kanetatsu then continues to argue with his men, but tells them to be in formation since where there is one oni, there are more. A much larger group of lesser oni then appear. Kanetatsu inspires the people and tells them that they have chances and he will slay a hundred oni in a single attack. Kanetatsu tells Masaki that he is angry since a hundred oni popped with no real arrangement, complete disorder. Angry, Kanetatsu uses his blade, binding the oni and slaying them in a single strike.

Kuroko, Kanetatsu, Masaki and other bushi arrive to attack some oni, who were attacking Musashi, Michiru and Akihiro. As the oni tell them to move as they want the obsidian goddess, Kuroko and Kanetatsu realize that Musashi or Michiru is the goddess. Kuroko goes and binds Michiru's wounds with her blade energy to stop her bleeding, while Kanetatsu and the rest defeat the oni. When three remaining oni consume on of theirs to become larger and stronger. Kanetatsu and the rest go protecting the castle from the other oni, while Kuroko stays with Musashi and Michiru. When Tatsuomi shows up, he buffs the Uesugi Bushi, who then easily defeat the remaining oni.
