Bleach: Season 15, Episode 331
After regaining her zanpakuto and reaper abilities, Nozomi decides that she wants to help defeat Kageroza, but is met with opposition from Ichigo and the other soul reapers since she cannot remember her zanpakuto's name or it's power. Ichigo, Chad, Ishida and Rukia decide to help Nozomi awaken her zanpakuto's dormant powers through the same rigorous training that Ichigo underwent to awaken his. Meanwhile, Kageroza orders the fakes of Byakuya, Hitsugaya, Zaraki, and Komamura to infiltrate the Living World. While traveling through the Precipice World, they fall into a trap set by Urahara and are separated when they finally do reach the Living World. To buy Nozomi more time to awaken her zanpakuto, Ikkaku and other soul reapers battle with the captains from the Invading Army. Yumichika tells Ichigo and the others that they won't awaken Nozomi's zanpakuto if both sides keep holding back. After Ichigo throws a Getsugatensho at Nozomi, she finally remembers her zanpakuto's name, Arazomeshigure, which seemingly swallows up all of Ichigo's zanpakuto's spiritual pressure.Ikkaku, who was fighting fake Zaraki, looks like he is about to be delivered the finishing blow when Nozomi arrives and seemingly obliterates fake Zaraki with her Arazomeshigure.
