Arc 7The Hueco Mundo Invasion
Tokoyo Misao pushed Soul Society toward reform and prepared for Aizen and the Quincy, while training allies and confronting Xcution. After Yhwach’s forces clashed with Aizen and Ulquiorra in Hueco Mundo, the Espada launched an invasion of Soul Society, where Ulquiorra and Yammy faced the veteran captains.
- Shunsui Kyōraku brought Ichigo Kurosaki and his companions to the captains’ meeting, where Gin Ichimaru revealed Aizen’s plan to create the Ōken using Karakura Town and explained how Aizen had taken a Soul King Fragment from Rangiku Matsumoto.
- Tokoyo Misao challenged Yamamoto over Rukongai’s suffering, and the captains approved reforms and plans to replace Karakura Town with a replica while preparing for Aizen.
- Tokoyo Misao trained Soi Fon, Unohana, Kenpachi Zaraki, and Yasutora Sado, but X power began clouding his judgment, forcing him and Zaraki to delay fusing with it.
- Tokoyo Misao exposed Tsukishima’s attempt to manipulate Lisa and confronted Kūgo Ginjō, who proposed working together through Xcution as the coming conflict approached.
- Months later, Ryūken Ishida secretly helped Tokoyo Misao and Kisuke Urahara intercept a Quincy ambush on Orihime Inoue, and they captured Bazz-B and Cang Du.
- Yhwach led the Quincy to Hueco Mundo and offered Aizen an alliance, but Ulquiorra fought Yhwach, revealed his Segunda Etapa, and drove the Sternritter to retreat.
- Aizen and Kaname Tōsen planned an assault on Soul Society to collect Soul Reaper souls, sending Ulquiorra and Yammy to lead the attack.
- Ulquiorra and Yammy invaded Rukongai, and Shunsui, Ukitake, and Unohana confronted them as Yammy unleashed Bala and a massive Cero.
