Genryūsai Shigekuni Yamamoto vs. Driscoll Berci

 is a battle that takes place during the Quincy Blood War, focusing on the conflict between Captain-Commander Genryūsai Shigekuni Yamamoto and Sternritter "O" Driscoll Berci after the latter's theft of Chōjirō Sasakibe's Bankai.

Prelude
During the Fall of the Seireitei, 9th Division Lieutenant Shūhei Hisagi finds himself confronted by Driscoll Berci. Some time later, a bleeding and overwhelmed Hisagi is thrown into a wall by Driscoll, who laughs and declares that it sucks to be weak like Hisagi is. With Hisagi realizing that he is hopelessly outmatched, Driscoll wonders if the former is afraid of his strength.

Driscoll explains that his Schrift, The Overkill, allows him to grow stronger with each enemy, ally, or wild beast he kills before noting that he has already killed a hundred people today and killed just as many the last time he was in the Seireitei, including a lieutenant just like Hisagi, who gasps upon realizing that he is the one who impaled Chōjirō Sasakibe. Suddenly, with Driscoll forming a javelin-like Heilig Pfeil between his Reishi Tekkō and throwing it at Hisagi to demonstrate how he killed Chōjirō, Captain-Commander Genryūsai Shigekuni Yamamoto appears in front of Hisagi and deflects the Heilig Pfeil with his hand, leaving it to crash into another building. Initially startled by this alongside Hisagi, Driscoll laughs maniacally and calls himself lucky since he came here for Yamamoto prior to proclaiming that he will be killing the latter with his own subordinate's Bankai.

Battle
With Driscoll using his Medallion to activate Chōjirō's Bankai, Kōkō Gonryō Rikyū, Yamamoto recalls seeing Chōjirō himself using it as a younger man and closes his eyes in sorrow. While a large energy disc forms above him and pours down columns of lightning, Driscoll claims that Yamamoto should be thanking him since Chōjirō apparently had not used his Bankai in over 2,000 years. Watching this in astonishment, Hisagi is intimidated by its Reiatsu and mentally admits that he had no idea there was a Zanpakutō other than 10th Division Captain Tōshirō Hitsugaya's Hyōrinmaru that could control the weather just before Driscoll blasts Yamamoto with a large bolt of lightning, causing Hisagi to call out to Yamamoto in concern.

After Yamamoto recalls his history with Chōjirō, who attained this Bankai to prove his strength to Yamamoto by scarring his forehead and trained extensively to become Yamamoto's right-hand man with it, Driscoll continues to blast a motionless Yamamoto with lightning, to Hisagi's concern, and questions if he has lost the strength to retaliate after being struck by his subordinate's Bankai prior to intensifying the lightning striking him. With Yamamoto remaining motionless once the lightning ceases, Hisagi assumes that he has lost consciousness and attempts to intervene, only for Yamamoto to demand that he wait, to Hisagi's surprise.

Annoyed by Yamamoto continuing to talk instead of shutting up and dying, Driscoll blasts him once more and questions if Yamamoto has had enough yet, but a grinning Driscoll is unnerved by Yamamoto simply asserting that he understands Chōjirō's frustration and walking forward. After angrily proclaiming that Chōjirō's Bankai was not this weak when he used it, Yamamoto releases his Shikai, Ryūjin Jakka, and unleashes a massive blast of flame that flays the skin and muscle off Driscoll's face and chest.

Aftermath
As his flames incinerate Driscoll, reducing him to a skeleton that crumbles into ashes, Yamamoto notes that he has finally given Chōjirō a proper sendoff and bids him farewell. Approaching a stunned Hisagi, Yamamoto promises that he will kill every last member of the Wandenreich himself and bursts into the air in a scorching trail of flame. With Yamamoto hurtling across the Seireitei like a comet, the other captains are alarmed and impressed by his rage. Far away, when her lieutenant, Marechiyo Ōmaeda, questions what this sensation is, 2nd Division Captain Suì-Fēng calls him foolish and declares that Yamamoto is furious.

As they run down a street, 5th Division Lieutenant Momo Hinamori observes that she has never felt Yamamoto get this angry before and her captain, Shinji Hirako, confirms that he has not seen this or Yamamoto fighting on the front lines before telling Hinamori that he will get to have all the fun if they do not hurry. Elsewhere, Hitsugaya points out how hard Yamamoto is fighting and tells his lieutenant, Rangiku Matsumoto, that they cannot let themselves be defeated, which she concurs with as Cang Du raises his Reishi Claws in response.

Simultaneously, 7th Division Captain Sajin Komamura rouses his subordinates by declaring that it would be disgraceful for them to lie down while Yamamoto still stands. With 7th Division Lieutenant Tetsuzaemon Iba and the other Shinigami standing up and loudly affirming this, Bambietta Basterbine stands opposite Komamura and expresses confusion at how they are doing this when they were almost dead moments ago. During this, 8th Division Captain Shunsui Kyōraku gets to his feet and observes that Yamamoto's Reiatsu is reverberating across the Seireitei as though he is telling Shunsui that he does not recall raising a coward who would struggle against someone of Robert Accutrone's level.

With Shunsui readying his Shikai, Katen Kyōkotsu, and rushing toward a shocked Robert while attacking, Royd Lloyd, who has copied the appearance and memories of Yhwach with The Yourself, holds an unconscious 11th Division Captain Kenpachi Zaraki aloft by the throat, identifies him as a Special War Power, and questions if this is the best he can do prior to assuming that he has overestimated the Shinigami and telling Kenpachi to go to sleep. Suddenly, Yamamoto slams into the ground behind Royd and notes that it has been a thousand years since they last met before proclaiming that he has come to annihilate Yhwach, causing Royd to grin at this.
