Renji Abarai vs. Yylfordt Granz

Renji Abarai vs. Yylfordt Granz is a battle during The Cold War that takes place in Karakura Town.

Prologue
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 what he sees as 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
Renji immediately activates his bankai and attacks the Arrancar. Yylfordt Granz is able to fend off Renji's bankai with ease and move in close to land a deep slash across Renji's chest. Renji moves to fend Yylfordt off and the Arrancar laughs questioning the power of Renji's bankai and muses that this is the best that a lieutenant of the elite Gotei 13 is capable of.

Renji soon receives assistance by Ririn, Noba, and Kurōdo. Ririn creates illusions while Noba teleports Kurōdo around to attack Yylfordt. He quickly disposes of the Mod Souls after releasing his spiritual power and using Sonído. As Jinta Hanakari is watching from the Urahara Shop's roof, he notices that Ururu Tsumugiya is reacting to the Arrancar's reiatsu and goes into Genocide Mode. She then attacks Yylfordt from behind with a kick, which sends the Arrancar flying with extreme force. She gets upon him quickly and grabs him by the throat stating he is danger and therefore an enemy and enemies are executed, all the while in a trance state. She then proceeds to brutally beat the Arrancar causing him significant injuries. Yylfordt manages to fend her off and as he promises to kill her for attacking him, he goes into his Resurrección. He impales Ururu on one of his bull-like horns and confronts a stunned Renji, explaining that this how Arrancar release their Zanpakutō.

He then flings Ururu away but she is caught by Jinta who takes his Kinabo and hits Yylfordt in the head with no affect. Before Yylfordt can harm him, Renji uses his bankai to block another impaling attack from the Arrancar, telling the kids to run away. Yylfordt laughs at the attempt to block him and breaks Renji's bankai and impales him as well. He then flings Renji away and states that since these are his last moments he will tell him his name and rank as a sort-of farewell gift. Shortly lieutenant Rangiku Matsumoto attains permission to release the limiters and informs the rest of the task force, to which Renji happily states that he was getting tired of waiting. Yylfordt asks Renji what a limit release is, as one of his horns is cut off. Renji explains that a limit release is a process applied to captains and lieutenants of the Gotei 13 to prevent unnecessary ripples in the balance of the Human World. The symbols of their respective divisions are placed on them to seal 80% of their Reiatsu but after getting them removed, your power becomes 5 times greater. Renji directs his bankai to attack Yylfordt, which the Arrancar blocks by grabbing its jaws but is pushed back and loses his left arm in the process. Realizing that they are no match, Shawlong Kūfang orders his group to retreat. But it is too late as Yylfordt tries to get away Renji uses his Hikōtsu Taihō technique to obliterate Yylfordt enitirely.

Aftermath
Yylfordt Granz falls to the ground after being obliterated by Renji's Hikōtsu Taihō. Renji moves himself to ground, grievously injured and kneeling in exhaustion as his Bankai collapses into its segments. Renji expresses his concern for Ichigo, thinking about how difficult his own fight against Yylfordt Granz was.
