Rukia tells Ichigo why the Shinigami defeated the Quincy 200 years earlier. Ichigo confronts Uuryu with this knowledge while they are fighting the Hollows. This makes Uuryu remember how his Sensei died. While reminiscing Ichigo and Uuryu notice they are surrounded by Hollows and must work together to defeat them. While they are fighting Urahara and his friends show up and defeat the Hollows. Now Ichigo and Uuryu can concentrate on the Menos, a gigantic Hollow formed from hundreds of Hollows, which just appeared in the sky.
