Synopsis
As the dome grows unstable and the Soul Reapers fight the Gillians outside, Ichigo fights Muramasa inside his inner realm, which is collapsing from the grudges of the hollows he consumed to sustain himself. Ichigo questions Muramasa's devotion to Kouga in spite of his apparent motives for freeing the zanpakutos, and insists that he should know what a true bond between a Soul Reaper and a zanpakuto is. Ichigo defeats Muramasa, causing the two to leave his inner world. Muramasa dies after realizing the error of his ways and Byakuya thanks Ichigo.
