Ch. 526Aizen's Downfall
Shiraishi and Gin Ichimaru killed Aizen with a surprise attack, though Shiraishi worried Aizen might return from Hell. Shiraishi then brought Retsu Unohana to heal Nelliel and was reminded that the surviving Arrancar army still needed attention.
- Shiraishi used the PROJECT skin’s hypnosis to help Gin Ichimaru land a poisoned Bankai strike on Aizen, then burned Aizen’s body and soul until his reiatsu vanished.
- Gin Ichimaru confirmed Aizen was dead, while Shiraishi worried that Aizen might return from Hell and left that question to Kisuke Urahara and the others.
- Shiraishi found Retsu Unohana and took her to a ruined hall where Nelliel lay gravely wounded beside Pesche and Dondochakka.
- Pesche and Dondochakka begged Retsu Unohana to save Nelliel, and she began treating her with Kaidō.
- Retsu Unohana told Shiraishi to handle the million Arrancar below so the Quincy would neither kill nor recruit them.
