Summary
As the dome grows unstable and the Shinigami fight the Gillians outside, Ichigo takes on Muramasa within his inner realm, which is collapsing from the grudges of the hollows he consumed to sustain himself. Ichigo questions Muramasa's devotion to Kōga in spite of his apparent motives for freeing the Zanpakutō, and insists that he should know what a true bond between a Shinigami and a Zanpakutō is. Ichigo defeats Muramasa, causing the two to leave his inner world. Muramasa dies in Ichigo's arms after realizing the error of his ways. As Muramasa fades away, the materialized Zanpakutō spirits all fade in the same fashion, returning to their original forms.

Ulquiorra and Nel tell Ichigo that the series won't be going back to the Hueco Mundo arc just yet. Ichigo is most upset to be the last person to know of this, being the main character. Ulquiorra asks the viewers to bear with them.
