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.

Hyottoko, a member of the Oniwaban group, raids Kamiya Dojo, where Megumi is hiding. He unleashes his special attack "Fire Breath," in which he breathes fire from his mouth, onto Kenshin and Sanosuke. Anticipating the defeat of Kenshin and the others at the appearance of the powerful middle-ranked spy, Megumi tries to flee the scene, but Kaoru stops her and says "He's fighting for you," telling her to believe in Kenshin's strength.
