Summary
In Las Noches, an Arrancar named Patros arrives in the room where the Hōgyoku is being kept, but he is caught by Ulquiorra Cifer, who reminds him that this is a place he cannot enter without the permission of Sōsuke Aizen. Patros, however, does not understand this reverence to Aizen and questions why they have to do what a Shinigami tells them to and why their freedom has been taken away. Feeling that Hueco Mundo has changed since Aizen arrived, Patros does not intend to obey a Shinigami and wants to use the Hōgyoku himself to control Hueco Mundo. When Ulquiorra does not think that someone who is not even an Espada can do anything, Patros reveals that he has two allies who promptly attack. Ulquiorra is caught off guard and is slashed and stabbed until he falls. Patros then takes the Hōgyoku and heads to the Human World with his allies to find the person who knows how to use it. Tōshirō Hitsugaya, Rangiku Matsumoto, Ikkaku Madarame, Yumichika Ayasegawa, and Renji Abarai all respond to the Arrancar arrival, though since Renji is furthest away, he is unable to join the others in facing off against Patros and his two allies, both of whom release their Zanpakutō.

While one Arrancar fights Hitsugaya and Rangiku and the other battles Ikkaku, Patros passes through the town, encountering Kon. Shortly thereafter, Renji finds a scratched up Kon, who reveals that Patros is headed for the Urahara Shop. Already there, Patros tells Jinta Hanakari and Ururu Tsumugiya that he wants to meet the person who knows how to use the Hōgyoku, but Renji arrives in time to tell him that Kisuke Urahara is not here. In fact, Urahara, Tessai Tsukabishi, and Sado Yasutora had earlier left to make some purchases to restock the store, leaving Renji and the others to tend to the shop. Since Patros wants to wait for Urahara’s return, Renji draws his Zanpakutō and starts to fight him. Ririn, Noba and Kurōdo return to their Human-sized bodies in order to help out. They save Renji from being hit again by Patros’ super-fast sword draw technique after he had already been knocked into the ground by it once. They then use their powers to catch Patros off guard and manage to land several hits, but the Arrancar soon turns the tables by knocking all three out. With Renji still rearing to fight, Patros proceeds to use the second level of his twenty level sword technique which hits with so much force that it knocks up a cloud of dust that covers the entire store. Unbeknownst to them, a recovered Ulquiorra has also arrived in Karakura Town.
