Ch. 81Nelliel
Ye Yang met Ulquiorra in Hueco Mundo to ask about Aizen and the search for Vasto-class Menos Grande. Their discussion was interrupted when Ulquiorra fought Nelliel Tu Odelschwanck, whose Cero Doble revealed her unusual ability to absorb Ceros; Ulquiorra regenerated from her attack and insisted their fight was not over.
- Ye Yang summoned Ulquiorra, learned Aizen had not appeared in Hueco Mundo, and warned him not to underestimate Aizen.
- Ulquiorra said recruiting more Vasto-class Menos Grande had been difficult, then attacked Hollows that had gathered to prey on them.
- Nelliel Tu Odelschwanck stopped Ulquiorra from killing the fleeing Hollows, and they fought over their opposing views on protecting the weak.
- Ulquiorra fired a Black Cero, which Nelliel swallowed and returned as a powerful Cero Doble that badly injured him.
- Ulquiorra severed his damaged arms, regenerated them with High-Speed Regeneration, and told Nelliel he still intended to fight.
