11th year of the Meiji Era in downtown Tokyo. Kaoru Kamiya, the acting master of the “Kamiya Kasshin-ryu” style, was chasing after the “Hitokiri Battosai,” who was claiming to be a user of her sword style. One night, Kaoru meets a man carrying a sword. She immediately questions the man, but he seems to have absolutely no will to fight. “Is this the rumored Hitokiri Battosai?” As Kaoru dubiously looks on, the man introduces himself as Kenshin Himura, a “Rurouni.”

After defeating Arundo Akamatsu, Kenshin returns to the Kamiya Dojo and sees Hajime Saito. Hajime had introduced himself to Kaoru and Yahiko as Goro Fujita, the police officer, and they had invited him into the Dojo without any suspicion. Hajime criticizes Kenshin and the others for their naivety. Over the past ten years that Kenshin had washed his hands of manslaying, Hajime had honed his killing intent and skills as a hitman, and now Hajime's ferocity was aimed at them.
