Sword of the Demon Hunter: Kijin Gentosho Novel Volume 4 was written by Motoo Nakanishi.

It is year two of the Bunkyu era. Six years have passed since the alcohol craze that stole yet more loved ones from Jinya’s life, but as time marches forward, so must he. The new era keeps Edo on edge as the anti-shogunate movement gains momentum with each passing day. Meanwhile, Jinya investigates rumors of a demonic sword and meets Hatakeyama Yasuhide—a samurai who serves the feudal lord of Aizu and has sworn loyalty to the shogunate. But just how far will this samurai go to prevent the shogunate from becoming just another relic of the past?
