Kenshin obtains a new sakabato. Having involved Seiku in this conflict, he decides to leave Aoiya before inviting any further danger. Meanwhile, Misao stops by Shirobeko, a beef hot-pot restaurant where Kaoru and Yahiko work part time, where she learns Kaoru is searching for Kenshin.

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.

Hoji plans an attack of Aoiya at night using a secret unit, the Owl Clan, in order to capture Okina and catch a hint of Kenshin's whereabouts, but instead the Owl Clan were the ones defeated. Okina challenges Aoshi to a battle via a member of the clan whom he sent back to Shishio's location.

Kenshin undergoes training so that he can learn the ultimate technique. He barely manages to get in a hit against Seijuro in a bout, where he then learns "Kuzuryuusen,"a powerful technique that launches nine slashes at the same time. Kenshin learns to see through Seijuro's swift sword movements and masters "Kuzuryuusen" by looking at it only once. However, the technique was only born out of the process of passing down the ultimate technique, "Amakakeru Ryuu no Hirameki" of Hiten Mitsurugi-ryu.

As a result of passing down the ultimate technique, Seijuro endures a fatal wound.

Shishio sends a dueling challenge directed at Kenshin, Hajime, and Sanosuke. The duel is to be held the next day on Mt. Hiei, northeast half way up the mountain in a small shrine with a six-storied torii. At Shishio's fortress, Hoji proposes a strategy to Shishio for an "absolute victory," when the Ten Swords assemble there.... And on the night before the duel, Kaoru talks to Kenshin as he stares up into the night sky.
