The second round of the Grand Tournament of the Shogunate's main battle has finally begun! The strongest remaining fighters gather at the former Kaga domain residence in Edo in the hopes of claiming the title of the ultimate peerless warrior!! There's also Gama, who has joined forces with Tadaie Hiramatsu, his vassal Bihomaru, and Iori, ablaze with fighting spirit to get his revenge against Tadaie. Soon the Shogunate's most powerful protectors, the “Unlimited Divine Soldiers” take to the scene! The Shogunate's aim? To annihilate any strong warriors in their way. The Unlimited Divine Soldiers' first target is none other than Bihomaru-it's the clash of the Shogunate and the Suruga domain! Meanwhile…Iori is set to inherit the Ogame style's sixth sword technique from Hanjiro Okamoto, but will he be able to master it?

It's the clash of Shura vs. Demon God!! Which one of them is the true strongest warrior? Ran's been kidnapped, and Iori challenges Bihomaru to get her back.

And it's with all eyes fixated on Gama and Yagira's fierce battle that the Unlimited Divine Soldiers finally make their move…!

On the exile island of “Ashura's Prison,” the main battle of the Grand Tournament of the Shogunate finally begins! Iori's first opponent is Kitaro Mashima of the Myojin style, with whom he shares a fated connection-Kitaro is none other than the elder brother of Sasuke, the "Crimson Ripper" of the Four Divine Spears against whom Zenmaru fought in the Grand Tournament of Unabara two years prior. Kitaro swears revenge, descending upon Iori like a wild beast, but it's nothing Iori can't manage and he quickly gains the upper hand. However when Kitaro's ear is sliced off, he undergoes a bizarre transformation and reveals his true colors!

It's the battle of Gama vs. Shinnojo!! Next thing they knew, their match had become a true showdown of life or death! In their battle of strength, Gama unleashes a tremendous blow with his sword that even Shinnojo has never seen before! Meanwhile Zenmaru finds himself in mortal combat with a fierce opponent! He may be an old man, and only number 99 on the Hundred Swords list, but his hand holds a deadly power. Zenmaru, lured into the forest by his enemy, finds himself caught in a brand new dangerous predicament!!

Upon arriving at the inn, Ran seeks the power to live by the sword and asks Iori for his tutelage. However Iori seems to have a lot on his mind after his battle with Raio. Before he can catch his breath, yet another of the Hundred Swords comes to attack. Iori finds himself surrounded by more than 30 skilled fighters, including rank number 54, Ikki Obayashi. Iori demonstrates demonic godlike swordplay only to find himself faced with an even more formidable foe!!

It's time for Zenmaru Ichinose to put his resolve to the test! Zenmaru, who has always been aware of the gap between himself and Gama and Iori, steps up to prove his swordsmanship against Homare of the Unlimited Divine Soldiers! Who will be the victor in this battle of brute strength versus brute strength...?! Next up is a one-on-one battle between Gama and Yagira, at the behest of the shogun himself! What is supposed to be a sudden-death match turns into an unexpected showdown of tactical skill...!

At long last, the main battle of the Grand Tournament of the Shogunate begins! Before the main battle, Iori receives a visit from Yagira, the Shogun's military strategist. Yagira fills Iori in on the secret of the Shogun's family that lies behind the scenes of the tournament, as well as the existence of a formidable warrior! Meanwhile, Gama is paid a visit by Shimon Kudo of the Muho style. Surrounded by three of the strongest disciples of the Muho style, Gama finds himself faced with a big choice!

Iori, Shungaku, and Gama! Just as a confrontation threatens to break out between these three strong fighters, they part ways with a promise to clash swords again in the main battle of the Grand Tournament of the Shogunate. Iori, who is struggling to enjoy his sword, leaves Gama and Zenmaru behind to set off for Edo! Ran goes after Iori, who teaches her the Ogame style, and she then challenges one of the One Hundred Swordsmen in order to obtain a scroll of her own. Her opponent is none other than Burai Udo of the Seishin style! Can Ran's swordsmanship hold up against a sword powerful enough to split boulders?!

It's been two years since the infamous Unabara Tournament, but things aren't over for Iori Sengoku-in fact, he's received a summons from the Tokugawa Shogunate.
