Bleach: Can't Fear Your Own World
After rescuing Grimmjow Jaegerjaquez, Kisuke Urahara, Yoruichi Shihōin, and Yūshirō Shihōin from Askin Nakk Le Vaar's Gift Ball Deluxe, Nelliel and Grimmjow saved Tier Harribel from Yhwach's dungeon in the Wahrwelt. With Nelliel carrying Harribel while leaving the Soul King Palace, they encounter Shunsui Kyōraku and Ichibē Hyōsube who are in the middle of turning Yhwach's corpse into the new Soul King. Before Grimmjow could attack the Shinigami who are surrounding them, Nelliel uses her Bala to stop and remind Grimmjow that picking a fight now, right after the Quincy were defeated, would make them the next enemies for Shinigami. Grimmjow is not perturbed in the slightest, arguing that they just need to kill them all, but he finally relents after Ichibē assured them they would be free to leave, after emphasizing the importance of the balance of three worlds for the moment. Before returning to Hueco Mundo, Grimmjow then considers fighting Ichigo, but Nelliel once again reminds him that Ichigo is still heavily injured and Grimmjow wouldn't be satisfied fighting the weakened Substitute Shinigami.

Six months after the Quincy Blood War, Nelliel, together with Harribel and several other Arrancar who used to serve Aizen, are gradually bringing back peace to Hueco Mundo by defeating the remaining Quincy. However, their peace is interrupted when a child clad in Shihakushō named Hikone Ubuginu arrives in Hueco Mundo and attacks them in an attempt to conquer them. Nelliel, together with Grimmjow, Harribel, and the Quincy Liltotto Lamperd and Giselle Gewelle, manage to wound Hikone enough to force a retreat through another Garganta.

Sometime later, Harribel and Nelliel are informed by Rudbornn Chelute that Grimmjow has left for Soul Society. While Nelliel is worried that Grimmjow wants to attack Ichigo Kurosaki, neither Harribel nor Rudbornn believe that even Grimmjow is that impulsive. Shortly afterwards, Harribel and Nelliel open a Garganta to Soul Society with the intent to recover Grimmjow.

As Harribel and Nelliel arrive in Soul Society, they are confused to find Luppi Antenor present and alive, as well as Quincy and Shinigami both fighting a gigantic, unknown Hollow controlled by Hikone. The Hollow, Ikomikidomoe, notices the new arrivals and addresses them, asking the female Arrancar if they are "misstresses" of Baraggan Louisenbairn. When an insulted Nelliel counters that Baraggan is dead, Ikomikidomoe reminisces about the former King of Hueco Mundo and lets out another massive roar.

Soon after, Ikomikidomoe proceeds to spawn a large amount of Hollows to attack the Quincy and Arrancar, and Nelliel confronts Grimmjow, demanding an explanation from him. Eventually, Hikone returns Ikomikidomoe to his sword form and prepares to leave through a Garganta. When the Quincy and Arrancar try to stop them, Hikone fires a Gran Rey Cero at them, though Nelliel reacts quickly enough to counter it with a Cero Doble alongside Liltotto's The Glutton. As both are exhausted from this, Liltotto ask Nelliel if the Arrancar wishes to resume their earlier battle from in Hueco Mundo, but Nelliel assures the Quincy that as long as they stay out of Hueco Mundo, she has no quarrel with them. While Grimmjow objects to this, they are interrupted by the arrival of Nanao Ise, who informs all present that Captain-Commander Shunsui Kyōraku requests their presence.

Sometime later, Nelliel alonsgside the other Arrancar, Fullbringers, and Quincy have gathered at Kūkaku Shiba's residence. As Yoruichi Shihōin explains the situation to Kūkaku, the tensions between the different groups are high, to which Kūkaku furiously exerts her Reiatsu and demands that everybody behave in her house, which earns her the respect of both Nelliel and Harribel, who note their surprise at Kūkaku's power despite not being a Shinigami.
