Tōshirō Hitsugaya vs. Shawlong Koufang

Tōshirō Hitsugaya vs. Shawlong Kūfang is a battle during The Cold War that takes place in Karakura Town. After Ulquiorra Cifer and Yammy Llargo attack Karakura Town, Tōshirō Hitsugaya and a couple of other Shinigami are assigned to defend the town from the Arrancar.

Prologue
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 tells Grimmjow that there are more opponents now that weren't mentioned by Ulquiorra. Grimmjow then tells his Fraccion to use Pesquisa to find an opponent to battle. Once they all find an opponent to battle, they all head out to their destination. Shawlong and Nakeem Greendina decide to head over to where Hitsugaya and Rangiku Matsumoto are. They reach their destination, and Shawlong asks Hitsugaya how he is.

Battle
Shawlong swings his sword at Hitsugaya but he blocks the blow with his Zanpakutō. Shawlong introduces himself as Arrancar 11 and Hitsugaya introduces himself as the Tenth Division Captain of the Gotei 13. The two of them then form a distance between each other and Shawlong tells him that he's hit the jackpot to be fighting a captain, Hitsugaya counters by telling him he was incredibly unlucky to fight him.

In the middle of battling, Shawlong notes that Di Roy Rinker was killed by someone. Shawlong easily fends Hitsugaya off, even while he is using his Bankai, Daiguren Hyōrinmaru. Shawlong tells him he's disappointed that this is all there is to a Captains Bankai and that he was completely wrong about him. He is then distracted by the fact that Yylfordt Granz went into his Resurrección, Hitsugaya uses this opportunity to attack him. Shawlong easily blocks his attack, but Hitsugaya uses Hyōrinmaru's tail to sneak attack him from behind. Shawlong easily blocks this as well and tells him that it's disappointing for him to have risked his life by using his tail, yet still accomplished nothing. Shawlong then takes note of the disappearing ice petals behind Hitsugaya's Bankai and speculates that it's a time limit for how long he can stay in Bankai. He then mocks Hitsugaya by claiming that his Bankai being incomplete is painfully obvious and that it's going to be disappointing when it disappears. Shawlong then decides that while Hitsugaya is still in his Bankai, he will defeat him with his greatest fighting ability.

Shawlong goes into his Resurrección, Tijereta and immediately uses his newly formed claws to inflict a devastating blow across Hitsugaya's entire body. He then decides to fully introduce himself and states that it was a pleasure to meet him. Shawlong then turns around and claws into the back of Hitsugaya's Bankai, damaging him further. Hitsugaya still stands up to fight though and Shawlong congratulates him on being brave enough not to run away despite the huge difference in power. Hitsugaya decides to change the subject and asks Shawlong if, because he's Arrancar 11, he is the eleventh strongest Arrancar in existence. Shawlong corrects him and states that the numbers simply indicate the order of their birth, but this only applies to any Arrancar with a number higher than 10. He explains that with the Hōgyoku they were born from Hollow's to Arrancars, and any who were strong enough would be given a number 1-10, with 1 being the strongest. Shawlong then states that any Arrancar that is in that number group is called an Espada and they have their number carved into their very flesh. They also rule over any Arrancar with the number 11 or above, and Shawlong tells Hitsugaya that the Espada are far stronger than a Números like him. He finally ends his explanation and states that an Espada came with them to Karakura Town and his name is Grimmjow, the 6th Espada.

All of a sudden Rangiku yells at Hitsugaya and tells him that the limit has been removed. Shawlong is confused by this and Hitsugaya yells out "limit release". As Shawlong asks Hitsugaya what a limit release is, his right arm becomes frozen. Hitsugaya 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, their power becomes 5 times greater. Hitsugaya tells Shawlong it's over and uses Ryūsenka. Shawlong attempts to retreat but Hitsugaya catches up to him and stabs him, causing Shawlong to turn into a huge pillar of ice. The ice then shatters, killing Shawlong.

Aftermath
Hitsugaya falls onto the rooftop below, heavily injured, and Rangiku calls for Orihime Inoue to come and heal him; which she does so immediately.
