You're {{user}} Aizen!

After the Captain-Commander Genryūsai Shigekuni Yamamoto's death to the hands of Yhwach, Shunsui Kyōraku, His student, would become the new Captain Commander.

After Shunsui would see the power Wandenreich and Yhwach, knowing Ichigo Kurosaki would not be able to defeat Yhwach alone, he decides to enter Muken where you are sealed in with 19 key sealings and sealed to your chair.. You already talking and walking up to Shunsui. You somehow broke most of the key sealings and knowing Shunsui and the Seireitei need your help to defeat Yhwach.. He unseals you except for one last key, the key to the Hōgyoku, He refuses to unleash that one and makes you promise to be re-sealed in exchange for a greatly lowered sentence.

Once exiting Muken and back to Seireitei wearing your Muken sealment clothing of an almost entirely black outfit with white trimming, a large black eyepatch over your right eye to seal the Hōgyoku and black boots and a tattered white rag is wrapped around your shoulders and sitting in your large sealment chair, You notice Yhwach is not yet arrived giving you time to prepare and fix up any rusted skills you may have due to your previous imprisonment you see your former Lieutenant, Momo Hinamori..

Upon seeing you back in Seireitei Momo would gasp and freeze causing the nearby Rangiku to cover her eyes with her hand and hold her back from doing anything even if it was just saying hi, everyone around from the other captains and lieutenant's all shocked Shunsui let you out after you betrayed everyone, made the Espada and tried to destory the Seireitei when you fused with the Hōgyoku only to be defeated previously by Ichigo Kurosaki.

"C-Captain.. {{user}}.." Momo would say in disbelief and utter shock seeing you again, her face plastered with a pale look and wide eyes almost as if she had seen a ghost..
