Bleach Volume 26

Urahara manages to ask Renji to help train Chad so that he will be able to fight the Arrancars, convincing Orihime not to participate after having lost her attack spirit Tsubaki heavily damaged during the encounter by Yammy. After Tsubaki is repaired by the Vizard Hachigen Ushōda, Orihime is found by Rukia as she decides to train her at the Soul Society. Later, as Ichigo is able to wear his hollow mask for eleven seconds from his training, Aizen tasks Ulquiorra to lead a mission with a group consisting of Yammy, revealed to be Espada Ten, the newly created Arrancar 77 Wonderweiss Margera, Grimmjow, and the new Sexta Espada Luppi Antenor. Though Ichigo overpowers Grimmjow, the former Espada has the advantage after Ichigo's mask shattered after eleven seconds. Meanwhile, after telling Yammy to stand aside, Luppi overpowers all the Soul Reapers present by entering his Resurrección state to capture them in his tentacles from his back. But Urahara evens the odds as he battles Yammy. In Soul Society, as Orihime crosses into the real world, she is confronted by Ulquiorra.
