The pursuers from the Oniwaban Group haven't made an appearance for over a week, and during this time Megumi familiarized herself with the Kamiya Dojo group. Sanosuke, however, was still unsettled and feeling frustrated knowing that Megumi was the one who made the opium that caused his friend's death. Then one day, Megumi suddenly disappears. In a letter they found from her, it stated that she had left of her own volition, but Kenshin and the others found this to be unnatural. They decide to head to Kanryu Takeda's residence, the man who was sending spies after her.

Raijuta, who wants to revive the murderous sword, considers Kenshin, who denies his idea, as an enemy. Raijuta initiates a fight using his actual sword, but Kenshin lands a blow that breaks Raijuta's sword and stops the situation from escalating further. After some time has passed, Yutaro, a boy who claims to be Raijuta's apprentice, arrives at the Kamiya Dojo. He claims he has come to challenge Yahiko, with whom he doesn't get along, to a match, but the way Yutaro holds his bamboo sword is no good...

Sanosuke is visiting the sukiyaki restaurant Akabeko, where he always leaves his bill on a tab. One of Akabeko's workers, Tae, asks him to go buy a Nishiki painting from the painting shop on her behalf. Though Sanosuke had no interest in paintings, he finds one at the store that catches his eye. It was a painting of the man he looked up to as his master back when he was a member of the Sekiho Army, Captain Sagara. With a gleam in his eyes, Sanosuke makes his way to meet with the artist of the painting.

The person who had sent Hajime to face Kenshin was none other than the Head of the Home Ministry, former Satsuma Domain Revolutionary warrior, Toshimichi Okubo. He asks Kenshin to go to Kyoto to stop the secret plans of a man who claims to be the legitimate successor of the Hitokiri Battosai. However, that man was supposed to have been killed 10 years ago by his own comrades in the government, as they regarded him as a threat. Receiving this request to conduct an assassination, what will Kenshin's answer be...?

Kenshin steps into Shingetsu Village, a place where the Mishima brothers escaped from. The village is currently under the control of Senkaku, Shishio’s subordinate, who rules with an iron fist and uses violence to control the villagers. They are frightened of the violence and unable to do anything but obey. The village has decayed and exudes an unusual aura about it. Kenshin heads over to where Shishio is located with Hajime, who’s learned about the current situation and visited the village. In the background of these events, Eiji’s heart burns with the desire for revenge against Senkaku.

Seeking a replacement for his broken sakabato, Kenshin visits Seiku, the son of highly honored swordsmith Shakku Arai, only to learn that he has quit making swords. Respecting Seiku’s philosophy of peace, Kenshin gives up his request for a new blade. Meanwhile, Ten Swords member Hoji Sadojima reports to Shishio on Kenshin’s movements.

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.

Shishio's underlings inconspicuously prepare for their battle plan when patrols arrive causing them to retreat.

Kenshin and Aoshi engage in a battle on the deck of the ironclad Rengoku. Behind the scenes, Sanosuke manages to board the ship and tries to blow up the engine room with the explosives he got from Tsunan. However, Shishio's underlings Hoji, Shuzo, Toshiro prevent him from going any further. Meanwhile in Kyoto, Arato faces off against Kamatari and Henya alone to buy time for the police forces to evacuate.
