Rukia Kuchiki vs. Di Roy Rinker

Rukia Kuchiki vs. Di Roy Rinker is a battle during The Cold War that takes place in Karakura Town.

Prologue
After Ulquiorra Cifer and Yammy Llargo attack Karakura Town, Rukia Kuchiki and a couple of other Shinigami are assigned 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 Koufang tells Grimmjow that there are more opponents now who weren't mentioned by Ulquiorra. In respnse Grimmjow tells them to use Pesquisa to find anyone with even a shred of Spirit Pressure. Once they all find an opponent to battle, they head out to their destination.

Di Roy Rinker heads out and finds Yasutora Sado. He nearly kills him but Ichigo Kurosaki appears and saves him. Sado runs away and Ichigo gets ready to fight Di Roy, however at this point Rukia appears behind him. She tells Ichigo to stand back because his Hollow might get out of control, despite this he refuses to retreat. Rukia then goes into her Shinigami form and explains that she got her power back because she got out of Kisuke Urahara's Gigai. Ichigo was held down by Chappy so that he wouldn't interfere with the fight.

Battle
Di Roy goes to attack Rukia but she blocks his blow with her Zanpakutō. The force of the blow sends them both through the town and Di Roy proceeds to send Rukia flying towards a pole. She gains her footing on the pole though and goes back to attack Di Roy. She swings her Zanpakutō at him, but he blocks the blow with his hand. He then introduces himself as the 16th Arrancar, in response Rukia begins to introduce herself as well until Di Roy tells her it doesn't matter since she and everyone else is going to be eliminated soon enough anyway. Rukia moves to create a small distance between the two and tells Di Roy that he should at least remember the name of her Zanpakutō. She then releases her Zanpakutō, Sode no Shirayuki causing her blade to become completely white.

Rukia uses Some no mai, Tsukishiro which forms a circle of ice around the two of them. Di Roy's legs begin to freeze, but he easily breaks out of the ice and goes up into the air. Di Roy tells Rukia that she won't be able to do anything with a sword that only effects the land. He lifts his eye patch, and begins to charge a Cero. However, the circle of ice becomes a beam of ice that shoots straight up into the sky and completely freezes Di Roy. As the ice begins to crack Rukia explains that her Zanpakutō can freeze anything within it's circle of influence. The ice then breaks, killing Di Roy.

Aftermath
Rukia gets out of her battle unharmed and goes back to where Ichigo is. Ichigo learns that Rukia has defeated Di Roy and is then given a full explanation on Sode no Shirayuki by Chappy, who also adds that Byakuya has prevented Rukia from becoming a seated officer out of concern for her. Rukia deactivates her Shikai and sheathes her sword and states that they should be helping the others fight. However, they are immediately confronted by Grimmjow who arrived after noticing that Di Roy was killed.
