Everyone's training for the coming battle with Aizen's herd of arrancars. When they arrive, however, no one is properly prepared. Grimmjow returns to Karakura Town, escorted by Yammy, Luppi, and Wonderweiss, all of them Espada except Wonderweiss, who is...weird. The clash goes poorly for Karakura's defenders. Until, that is, Aizen's true objective becomes clear and the fight becomes moot.
