Arc 12The Traitor Extermination
Asano Kiyoshi survived a nightmare in which Nel died, then led the Shinigami through the Dangai to defeat the Ryūtoji Clan and contain the Memory Bead’s threat. After reaching Seventh Class Reiatsu and freeing Senna from the Kihon’s influence, he began trying to stabilize the captured world.
- Asano Kiyoshi refused to abandon Nel, but Aizen wounded her, and she sacrificed herself after sharing a final kiss with him, and Kiyoshi unleashed his Bankai and killed Aizen before waking from the nightmare beside Nel.
- Asano Kiyoshi promoted Shūsuke Amagai, reviewed Nel’s reforms, and prepared for the nobles’ rebellion after Mayuri Kurotsuchi exposed their hidden Dangai routes.
- Asano Kiyoshi revealed that he had learned Bankai and led six captains and around five hundred combatants through the Dangai, where Nel and the Kidō Corps helped the force overcome waves of explosive Kihon.
- Asano Kiyoshi used his Bankai to destroy the Kihon horde and open a route to the Ryūtenji Clan’s world, then assigned the captains to protect the passage while he pursued the enemy.
- Asano Kiyoshi and the Shinigami fought the Ryūtoji Clan as Enyū and Yan Long formed a giant from Kihon, trees, and flesh, and Kiyoshi coordinated the captains and Kidō Corps to bring it down.
- Asano Kiyoshi used Strike Boundary against the giant, then restrained Senna with the King's Seal and Scroll to remove the Kihon pressure inside her after she affirmed that she was a real Shinigami named Senna.
- Asano Kiyoshi advanced from Sixth Class to Seventh Class Reiatsu and discovered new Scroll abilities, while Senna released Miroku Maru to sweep away the remaining Kihon.
- Asano Kiyoshi rejected Mayuri Kurotsuchi’s offer to experiment on the world and began trying to stabilize it as Mayuri analyzed how it might connect to Soul Society.
