When Ichigo attempts to fight Renji, he learns that each zanpakutō sword has a unique form that can be accessed only when the Soul Reaper discovers its name. Renji uses his transformed zanpakutō Zabimaru to overwhelm Ichigo. But Ichigo makes a comeback against Renji, overwhelming him and almost defeating him. But Byakuya steps in and defeats Ichigo at an overwhelming pace. Rukia returns to the Soul Society to await execution for her action so that the now powerless Ichigo can be spared. Urahara heals Ichigo's wounds at his shop, and begins training him so he will recover his spirit energy and possibly survive against the Soul Reapers within the Soul Society.
