Arc 18From Hueco Mundo to Zuellni
Shiraishi survived the conflict with Munemasa, reunited with Kūkaku, and later fought through Hueco Mundo while Azashiro pursued his plans. In Zuellni, Shiraishi reunited with Rukia and Ichigo, and the group set out to find Ishida and reach Silbern.
- Shiraishi killed Munemasa, ending Infinity’s control, while Byakuya and Isane treated the wounded Kūkaku and Azashiro later helped her escape Seireitei.
- Kūkaku found Shiraishi training in a garbage-filled cave, confessed her love while choosing to leave, and Shiraishi proposed they spend ten days together.
- Azashiro sent modified souls into Hueco Mundo with Shiraishi, who hunted Adjuchas and descended with him into the Forest of Menos.
- Shiraishi and Azashiro ambushed Nelliel, but their battle destroyed Azashiro’s fused space and left Nelliel injured, so Shiraishi saved and cared for her.
- Ichigo met Rukia while searching for Silbern, and they traveled to Zuellni to ask Sora Inoue for Kisuke Urahara’s Garganta Device.
- When Hollows attacked Zuellni, Shiraishi appeared and killed Shabotas, then learned from Rukia that the Seireitei had been destroyed and the Gotei 13 scattered.
- Ichigo told Shiraishi he wanted to find Ishida, and Shiraishi agreed to travel with him toward Kūkaku and Silbern while Sora asked them to take Orihime along.
