Genryūsai Shigekuni Yamamoto vs. Driscoll Berci

Genryūsai Shigekuni Yamamoto vs. Driscoll Berci is a fight that takes place during the Quincy Blood War between Captain Commander Genryūsai Shigekuni Yamamoto and Stern Ritter O Driscoll Berci.

Prologue
Having arrived in Soul Society, Driscoll Berci engages in combat with Lieutenant Shūhei Hisagi. Driscoll pins Hisagi against the wall before commenting how painful it is to fight someone so weak. Driscoll asks Hisagi if the Lieutenant is afraid of his power. He tells Hisagi that Juhabach gave him the letter O, the Overkill as the more opponents he defeats, the stronger he becomes. He then forms a lance in his hands, throwing it at Hisagi. However, the lance is caught by Yamamoto, who has just arrived. Upon seeing Yamamoto, Driscoll laughs, saying that he came here to meet Yamamoto and that he will kill him with his subordinate's Bankai, holding his medallion for Yamamoto to see.

Battle
Driscoll activates Chōjirō's stored Bankai as pillars of lightning form around him. Yamamoto stays motionless, closing his eyes. Driscoll asks if seeing the Bankai is nostalgic and says that he heard that it had not been used in over 200 years. He tells Yamamoto that he should be thanking him for showing it to him once more. Hisagi, still pinned to the wall looks on in awe of Chōjirō's Bankai, stating it manipulates the weather and is the only such Bankai he has seen other than Captain Tōshirō Hitsugaya's Daiguren Hyōrinmaru. Driscoll proceeds to unleash the power of Chōjirō's Bankai upon Yamamoto, who simply sits and takes the attack as Hisagi calls out to him.

As Driscoll continues to pummel the Captain Commander, the old man continues to sit and take the attack. Hisgai cries out once more as Driscoll asks if Yamamoto truly does not have the strength to defend himself. The Stern Ritter continues to taunt the Captain Commander, telling him to say something. Hisagi notices that Yamamoto has lost consciousness and rushes to help but stops as Yamamoto finally speaks, yelling to wait. Driscoll asks Yamamoto if he really still has the strength to speak and tells him to just shut up and die before hitting him once more with a large scale lightning attack. As Yamamoto gets up, Driscoll laughs, stating Yamamoto really does not want to die. Yamamoto stands and begins to speak out to Chōjirō, saying mortified. Yamamoto continues, saying that the Bankai that his friend and long time subordinate spent so much time improving, was not so weak. As he says this, he unleashes the flames of his Shikai, searing the flesh off of Driscoll's bones and killing the Quincy.

Aftermath
As Driscoll's bones turn to ash, Hisagi looks on in pure awe. Yamamoto tells the Lieutenant not to worry, as he will kill everyone in the rebel army with his own hands. He takes off in a burst of speed across the battlefield. Lieutenant Marenoshin Ōmaeda asks his captain what is happening and she tells him that Yamamoto has become enraged. Captain Shinji Hirako and Lieutenant Momo Hinamori both comment that they have never seen Yamamoto so angry as Shinji says that if they do not hurry, Yamamoto will steal all the fun. As Yamamoto continues to rush across the battlefield, he inspires new found hope and morale in the Gotei 13 members fighting the invading army. He rushes in a blaze of fire towards the Quincy leader, Juhabach. When he arrives, he states that it has been a thousand years since they last met and that he has come here to annihilate him.
