Kenshin receives a request from the police chief, asking for his help to take down “Kurogasa,” a serial killer who has been repeatedly targeting former Revolutionary warriors. Kenshin and Sanosuke go to escort Jusanro Tani, who received a letter containing a death threat. As warned in the letter, at 1:00 a.m. sharp, Kurogasa appears. His true identity was Jine Udo, a vagabond slayer who had made a name for himself in the assassination business since the Bakumatsu Era.
With a ruthless ex-Samurai killing high ranking politicians, the Chief of Police asks Kenshin to catch him. But as Kenshin confronts the deadly Jin-nai Udo, Kaoru’s efforts to stop the battle end with her kidnapping.
