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 reunites with Kaoru and the rest at Seijuro Hiko's place, who is a master of Hiten Mitsurugi-ryu. Seijuro learns from Kaoru that Kenshin goes around the country acting as a rurouni who helps people, when he then decides to pass down the last ultimate technique of the Hiten Mitsurugi-ryu.
