Going back in time, the 4th year of Keio. Kenshin is suffering from a high fever in the main hall of a desolate shrine. Kenshin falls asleep and when he awakens, he finds himself being nursed back to health by former private detective Giichi and his wife Satsuki in their home.

Kenshin and Hajime realize that Shishio has another objective in mind that lies in Osaka. They meet up with Sanosuke there. To stop the Great Kyoto Fire, Kenshin asks for help from everyone at Aoiya via a letter while leaving Ryusaku Arato, the chief of police, in charge of supervising on the ground in Kyoto. Kenshin, Hajime, and Sanosuke head to Osaka Bay on a carriage after they finish their errands. Then, senior police officer, Hikozaemon Omi brings along Juro Kitazawa, a young 11-year-old boy who says he wants to meet with Arato.
