Renji Abarai vs. Yylfordt Granz

Renji Abarai vs. Yylfordt Granz is a battle during The Cold War that takes place in Karakura Town. After Ulquiorra Cifer and Yammy Riyalgo attack Karakura Town, Renji Abarai is assigned to a task force of Shinigami led by Captain Tōshirō Hitsugaya that goes to defend the town from the Arrancar. At the same time Grimmjow Jaegerjaquez decides to go to Karakura Town with his Fracción because of Ulquiorra's failure to kill Ichigo Kurosaki. When they get there Shawlong Kūfang informs Grimmjow of additional presences that weren't mentioned by Ulquiorra and Grimmjow tells them to use Pesquisa to find an opponent to battle. Once they all find an opponent to battle, they all head out to their destination. Yylfordt heads toward the Urahara Shop and confronts Renji Abarai. After Yylfordt arrives, he senses Di Roy's defeat and remarks to Renji on how lucky Di Roy's opponent was since the Arrancar was not a very skilled warrior.

Battle
During the fight, Renji seems to be struggling as he had released his Bankai. Yylfordt Granz is clearly shown to be overpowering Renji, having easily injured him without his Resurrección. Though the fight between the two is briefly interrupted as Renji receives some assistance. In the anime, Renji was assisted by Ririn, Noba, and Kurōdo. Ririn created illusions while Noba teleported Kurōdo around to attack Yylfordt. He quickly disposes of the Mod Souls after releasing his spiritual power and using Sonído. In the manga, Jinta Hanakari watching from the Urahara Shop's roof notices that Ururu Tsumugiya is reacting to the Arrancar's reiatsu and goes into Genocide Mode. She then attacks Yylfordt in a robotic state of mind. Her brute strength causes some head injuries to Yylfordt, causing him to go into Resurrección in retaliation.

With his power released, he brutally stabs Ururu and takes a direct hit from Jinta Hanakari's bat with no injuries. Renji then intervened and saved both the children but Yylfordt's horn pierces through Renji and his Bankai. Thinking that Renji was now finished, he gives his name and rank as a sort-of farewell gift. However, Renji releases his limiter to which Yylfordt questions what it is. Renji explains the process of the limiter and then attacks Yylfordt who is unable to hold back the attacks any longer, seeing as how Renji is now five times stronger. The Bankai charges Yylfordt and he manages to grab its jaws but loses his left arm in the process. Realizing that they are no match, Shawlong Kūfang orders his group to retreat. Unfortunately for Shawlong's group, all die at the hands of their Shinigami opponents with Renji using Hikōtsu Taihō to obliterate Yylfordt.

Aftermath
Yylfordt Granz falls to the ground after being obliterated by Renji's Hikōtsu Taihō. Renji is grievously injured and is seen kneeling on the ground in exhaustion after his Bankai collapses into its segments. While he is kneeling, he is seen being concerned for Ichigo, seeing as how difficult his own fight against Yylfordt Granz was.
