Bleach Volume 68

The remaining captains and lieutenants join Urahara and his group with the purpose of being transported to the Spirit King Palace. Meanwhile, Ichigo and his friends arrive at the palace and confront Yhwach, but Ichigo's Quincy blood forces him to unwillingly kill the Spirit King, starting the destruction of the Soul Society, Hueco Mundo, and the real world. In response, Ukitake releases Mimihagi, the Spirit King's animate right arm who Ukitake hosted since he was young, to stabilize the Spirit King and Kyōraku releases Aizen from the Muken. At the palace, Uryū and the Schutzstaffel (elite guard) join Yhwach's battle against Ichigo's team, allowing the Emperor to assimilate the King and Mimihagi. The overflow of power creates a mass of black monstrosities which descend upon the Seireitei. The Shinigami fight the creatures until they are joined by Aizen, who destroys all of the creatures with his new tremendous power.
