Summary
In the 4th Division compound, more injured Shinigami keep arriving, putting a strain on the division's resources. Captain Retsu Unohana requests that her Lieutenant Isane Kotetsu assist. Although reluctant, she agrees. Captains Jūshirō Ukitake and Shunsui Kyōraku discuss the only partially-successful bid to capture several Zanpakutō at once, remarking that it will not be long before the captain-class Zanpakutō begin attacking. They also discus the situation with the 6th Division, which is without its captain, Byakuya Kuchiki, during the current emergency.

While Lieutenants Momo Hinamori and Rangiku Matsumoto head out, Ichigo Kurosaki continues his search for Byakuya. Haineko and Tobiume tease each other and compete to find Hyōrinmaru, but are startled by the appearance of Senbonzakura, who is looking for Muramasa. Neither Tobiume nor Haineko have seen him. After Senbonzakura leaves, the pair see Ichigo and attack him. However, as they attack, Hinamori and Matsumoto arrive to fight their Zanpakutō, allowing Ichigo to continue his search. Ichigo, however, is attacked by Hyōrinmaru before he finds Byakuya. A somber Hyōrinmaru questions Ichigo about his Zanpakutō, commenting that he does not wish to fight Ichigo if he is not his former master. Hyōrinmaru admits that he does not know the name of his master or his own name. As he attempts to trap Ichigo with Sennen Hyōrō, Tōshirō Hitsugaya tells him that his name is Hyōrinmaru and that he belonged to Hitsugaya.

Meanwhile, a visibly weakened Muramasa limps through the Forest of Menos in Hueco Mundo and is attacked by a Hollow, which is slain. Later, Muramasa encounters a group of Gillian, who also attack him. He is later shown limping away from their dissipating bodies.
