A swordsman who murdered Kakunojō's parents and attempted to kill her, whose face was forever to be remembered by Ebisu. Hario is a bearer of the ancient Jiwari-ken technique of swordsmanship, which attempts to create a continuous fissure within the earth's surface as a result of the vertical movement of one's sword, but which is stopped with the application of water within its path. He later serves in Yokohama as Kawai Tsuginosuke's bodyguard, as ordered by Nakaiya Jūbē, and is instantly recognized by Ebisu, who moves to inform the rest of the troupe and later traces him to an underground auction held in the Shanghai Club, where Hario had been accompanying Kawai. After witnessing Akizuki's attempt to destroy the Hasha no Kubi, Hario becomes very intrigued with Akizuki and attempts to find and kill him the next day, to the extent of even ignoring his job to protect Kawai and his Gatling guns. Later, Hario is cornered by Akizuki and the Yuyama troupe in the midst of a sun-brazen wheat field, and when they attempt to kill him, a sniper, Saiga Magozō, sent by Nakaiya, attempts to shoot him, and Hario soon dies.
