Arc 7Return from the Valley
After the Hōgyoku fused with Rei, he vanished into the Dangai while Soul Society and Aizen’s forces fought over Hueco Mundo and the Hōgyoku. Years later, Rei escaped the Valley of Screams, returned to Hueco Mundo, and forced Baraggan to join his campaign against the Soul King Palace.
- Rei’s clone fought Ichibē Hyōsube while Negación extracted the Espada and other fighters from Soul Society.
- Rei returned to Las Noches, took Kisuke Urahara’s Hōgyoku, and fell asleep as it fused with the Hōgyoku in his chest.
- Yama-jii led the Gotei 13 into Hueco Mundo, where Soul Reapers and Espada fought while Aizen entered Rei’s training room and removed the Hōgyoku.
- Rei awoke and fought Aizen and Yama-jii as Kyōraku battled Ulquiorra, Yama-jii fought Starrk, and the battles devastated Las Noches.
- The Soul Reapers withdrew after Rei and the Espada seemed to fall, while Rei drifted through the Garganta and awoke in the Sixth Valley of Screams.
- Rei studied the Blanks for years, reshaped the Valley of Screams into the Great War Spear, and broke through into Hueco Mundo.
- Rei confronted Baraggan at Las Noches, overwhelmed him, and made him agree to join the campaign against the Soul King Palace.
