After the Imperial Envoy is murdered, a citywide hunt for all samurai begins. The team plans a fast escape, but blundering Kikuchiyo seizes the moment to prove himself to the team.

Kambei is in a prison cell, awaiting his fate as the purported assassin of the Imperial Envoy. But the turmoil at the Capital is far from over; a political whirlwind has engulfed the empire with Ukyo at its center.

Little is known about the Capital and the divine ruler responsible for the rise of the Merchants, the energy trade, and the Bandits torment of the peasants. With sword in hand, Kambei is about to find out more.

With Kambei pardoned, Sanae and Muzuki freed, and peace promised to Kanna, it seems the samurai’s work is done. But Maro has a warning: the true struggle has only just begun.

Kambei is to be executed in a public display. Kikuchiyo and Katsushiro’s rescue party arrives just in time to hear the news of their leader’s scheduled beheading. Can they battle quickly enough to save him?

Kambei’s rescue has created deep rifts between Katsushiro and his sensei. At a time when every move is critical, with Ukyo’s plot rapidly unfolding, can the samurai survive their team being split in two?

Ukyo is calling on ronin to defend other villages from the Bandits, while secretly ordering the Bandits to increase their attacks on the villages. All the while, he’s planning to burn Kanna to the ground.

Katsushiro has returned to Kanna to defend it from the approaching Capital. Meanwhile, Kambei and the rest of the samurai are racing toward the Capital as well, poised for the final showdown.

Knowing that the Nobuseri will be searching for them soon, Kambei decides the group must go to Kanna. To avoid detection, they divide into small groups and take three separate paths to the village.

The samurai must come to terms with the aftermath of battle. They can’t look to Kambei for leadership; he departs on a solitary trek to the Guardian’s cave, having an even more perilous mission in mind.

The samurai must leave the caves to rescue Kikuchiyo, but as soon as they reach daylight, the towering machines ambush them. Clearly a traitor is in their midst.

Kanna is bombarded by rainfall as the Bandits make their final assault on the village. They attack from every direction, and in the battle’s furious climax, it becomes clear that not all of the samurai will survive.

Kambei leads the samurai into a city of relaxation and pays a visit to an old friend from the Great War, Shichiroji. He now lives a peaceful life with a woman he adores. Will he take up his sword again?

While Katsushiro and Kirara battle with their feelings for each other, Kyuzo embarks on a solo mission into the heart of the enemy camp.

Kambei’s frustrated group hears of a wandering, moneyless man who chops wood with his sword to pay for meals. As they soon learn, that is only the start of this nomad’s peculiar, rice-loving, philosophizing ways.

Kambei initiates a bold plan - handing Kyuzo, Gorobei, Katsushiro, and Kikuchiyo over to the enemy. Can the samurai defeat the Bandits from the inside of their own massive ship?
