Genryūsai Shigekuni Yamamoto vs. Yhwach

Genryūsai Shigekuni Yamamoto vs. Juhabach is a battle between the Captain-Commander of the Gotei 13 and the Emperor of the Vandenreich. It is also the final battle of the Captain-Commander.

Prologue
Quickly realizing that he is an imposter, Yamamoto shouts out and asks who he is. Before he receives an answer, there is a large explosion distantly behind him. Looking back, Yamamoto realizes that the First Division barracks are in flames and voices his concern for his Third Seat Officer. In addition, the real Juhabach appears behind him. As Juhabach thanks Royd Lloyd for his work, Yamamoto is shocked to find that he fought an impostor. Greatly pleased by his leader’s praise, Juhabach then kills him within an instant. Rather than questioning Juhabach about the current scenario, Yamamoto inquires of his activities while Royd has been impersonating him. In response, Juhabach asks him about what is beneath the First Division barracks, which is the Central Underground Prison, where Sōsuke Aizen is imprisoned at. Surprised at this, Yamamoto is silent as Juhabach states that he came to speak to the traitorous Shinigami.

Battle
Juhabach tells him that he wanted to recruit Aizen as a Special War Power for the Vandenreich, but Aizen naturally refused. Stating that this poses no problem, Juhabach asks if Yamamoto used up his power fighting his decoy. Reacting quickly, Yamamoto tries unleashing his Bankai again, only to have it stolen by the Vandenreich leader. Juhabach rebukes Yamamoto’s earlier reasoning for why the Vandenreich did not steal Yamamoto’s Bankai earlier by revealing that only he could handle Yamamoto’s enormous power; therefore, Royd made no attempt to do so while fighting the Shinigami. As Juhabach wonders if he should use the power of Zanka no Tachi, Minami: Kaka Jūmanokushi Daisōjin against the elder Shingigami, Yamamoto tries to take action against the Quincy. Before he can do anything, Juhabach summons a Reishi Broadsword. Juhabach then bids to the Captain-Commander and slashes Yamamoto.

Recalling earlier memories of when he had fought against a powerful threat to Soul Society, Yamamoto is silent as the result of Juhabach’s attack is revealed to be that Yamamoto has been bisected from his shoulder to his waist. Juhabach proceeds to berate him for looking so pitiful to die in this manner and attempts to leave. However, despite falling down dying, Yamamoto grabs a hold of Juhabach’s cloak in his final act. Cutting off the Shinigami’s arm, he tells Yamamoto that his attempts to stop him, even in death, are meaningless. He proceeds to further humiliate Yamamoto by stepping on the Captain-Commander’s head and explains that he never listed him as a "Special War Power" because of his foolish reluctance to exploit others. He rhetorically asks why Yamamoto never let Orihime Inoue heal his left arm, only to state he knows that it was because Yamatoto simply did not want to rely on a human. He goes on, saying that he knows that Yamamoto was uncomfortable about relying on Ichigo Kurosaki, even during the battle with Aizen. He tells Yamamoto that the reason he lost was because he grew weak from trying to shoulder the burden of protecting both Soul Society and the world alone. Stating that the original Gotei 13 was a group to be feared when Yamamoto did whatever it took, he then remarks that Soul Society will die soon but unbeknownst to him, the Gotei 13 died 1,000 years ago. Unleashing innumerable arrows from an outstretched finger, he obliterates Yamamoto's body entirely.

Aftermath
With Yamamoto’s death, Juhabach proceeds to have his forces finish up demolishing Soul Society.
