A Horror that inhabits a katana. A skilled swordsman named Juzo Igari on his quest in search for stronger men, possibly with a wish to die by the sword as he is ill and have little time to live, found the man who previously wielded the cursed katana by chance and slain him. He took the katana as it promises to heal him in exchange for Juzo cutting down living people for their blood. It took the Horror several centuries to heal Juzo as his body was too broken, ending up with Juzo revived in the modern era. To its chagrin, Juzo proves to be an honorable man who would not cut anyone down without a reason, asserting that he lives only to fight the strong. Juzo saw Rei by chance when the later was exterminating Rebecca and promptly challenges him to a duel when Rei was done with his job. The horror, however, refuses to abide by Juzo's wishes and Rei refuses to draw his blades on a human. The Horror demands Juzo to quench the blade with blood of the living before it can be drawn to fight the Makai Knight. Both men later ended up fighting with broom sticks, with Juzo demanding Rei to put on his armor but Rei refuses to do so as Juzo is not a Horror. The duel cannot be truly concluded since none of them is down, though impressed by Juzo's skills, Rei admitted defeat. Disappointed and refusing to just cut anyone down, Juzo commits seppuku to quench the blade's thirst as well as to free himself from a meaningless life. Surprisingly, as noted by Silva, Juzo's dead body reemerged as one possessed by a Horror yet unlike many other cases, Juzo's soul is firmly in control. Juzo's will is even powerful enough to wield one of Rei's swords effectively, despite having never even touch soul metal before. Eventually both men had their showdown, one between a Horror and a Makai Knight. Juzo is eventually slain as a Horror, dying with satisfaction under the blade of one stronger than he is. He hands Rei his wakizashi before turning into ash.
