A persistent nightmare comes true when Kenshin's old enemy, the former leader of a shadowy anti-Royalist organization, is hired to assassinate him.

Saito sets a trap for Kenshin by enlisting another assassin in his plan. And once Kenshin repels the accomplice, he's left to take on his old rival.

After stopping a fatal battle with Hajime Saito, a top government official asks Kenshin's help in killing a shadowy assassin who's threatening the future of the regime.

While preparing to give his decision on helping to kill Shishio, Kenshin learns of the Home Minister's murder.

Following Kenshin's departure from the dojo, everyone, and especially Kaoru, are sad at being left behind. And while Saito tries to dissuade Sanosuke from following him, Megumi sends Kaoru to deliver some medicine that will aid in Kenshin's fight .

In the wake of Kenshin's departure, everyone at the dojo is anxious to join the battle against Shishio. With Sanosuke, Kaoru and Yahiko in pursuit, Kenshin encounters Misao, a young girl who also happens to be a clever thief.

After befriending Misao, Kenshin insists that she return the money she's stolen before letting her accompany him on his quest to stop Shishio.

When he and Misao come across a village terrorized by forces loyal to Shishio, Kenshin enlists Saito to help liberate it from the evil gang.

Leaving Misao behind, Kenshin and Saito make their way inside Shishio's fortress. Following a confrontation with one of his most powerful henchmen, Kenshin is ready to take on Shishio himself.

Following Kenshin's defeat of the giant Senkaku, Shishio pits him against the young, emotionless assassin responsible for the Home Minister's murder.

As Kaoru and Yahiko continue tracking Kenshin, Sanosuke encounters a fallen Buddhist monk who offers to teach him some powerful fighting techniques.

As the showdown with Shishio approaches, Misao finds someone who could produce the sword Kenshin needs, only to be is disappointed when Shakkuu Arai refuses.

After watching an unarmed Kenshin bravely defend himself, Shakkuu Arai's only chance at saving his own son is to deliver his father's final reverse edge sword.

To prepare for Shishio, Kenshin asks a former teacher to help him master the last of his fighting techniques. However, Kenshin is distracted when Kaoru and Yahiko finally catch up with him after their long journey.

Although Misao is excited by the return of her mentor and hero, she's stunned to discover that Aoshi has betrayed one of their closest friends.

As Kenshin struggles to learn, Sijuro teaches him the most secret of his fighting techniques. And though Kenshin doesn't want to kill, it's inevitable if he is to beat Shishio. Meanwhile, Sanosuke is arrested during his search for Kenshin.

While waiting in jail, Sanosuke learns of Shishio's plan to overthrow the government by recruiting a deadly band of Samurai, including the blind warrior Usui, to defeat Kenshin and Saito.

Reunited with Sanosuke, Kenshin lays plans to stop Shishio from burning Tokyo to create the confusion he needs to overthrow the government. But Shishio harbors a surprise with his newest weapon, an ironclad battleship hidden inside another.

After Kenshin, Saito and Sanosuke destroy his battleship, Shishio issues his challenge for a final confrontation. And following Misao's defeat of the blind Samurai, Usui, Kenshin vows to spare the life of her mentor, Aoshi.

As Shishio prepares for battle, a henchmen suggests a plan to weaken Kenshin and his forces, ridding them of any opposition once and for all. As the moment of truth draws near, Sanosuke is pitted against Anji.

During his battle with Sanosuke, the fallen monk recalls how his hatred was born during an anti-Buddhist movement.

In his defeat of Usui, Saito exposes the blind warrior's plot to kill Shishio. And while Kaoru, Yahiko and Misao are preparing to defend themselves from an ambush, Kenshin readies for his fight against Aoshi.

Kenshin sets out to honor his promises to both fight Aoshi and bring him back alive to Misao.

Following his defeat by Kenshin, Aoshi vows to renounce Shishio. And while Shishio looks for clues to help in his impending fight with Kenshin, Kaoru, Yahiko and Misao fight to stay alive.

After Yahiko's fighting skills are stretched to the limit during his defeat of Shishio's warrior, it's now up to Kaoru to enter a battle of her own.
