Rangiku's Tears, the Sorrowful Parting of Brother and Sister

Although Yui is able to resist the arrancar and keep Shouta safe, the original arrancar devours her. It is overpowered by Hitsugaya and Rangiku, and stalls them by revealing that Yui's trapped soul will be destroyed if they kill him. It creates hundreds of copied arrancar to attack the town while it hides behind a barrier. Hitsugaya uses his bankai in an attempt to find the arrancar by freezing the surroundings. Rangiku and Shouta manage to track the arrancar via the song it sings, and Hitsugaya disables it with his bankai. Rangiku and Shouta defeat the arrancar, releasing all the souls it devoured in the process. With the arrancar gone, Rangiku sends Shouta to the Soul Society to reunite him with his sister.
