Your loyalty to Aizen was incomparable to all the other Espada, you're his best creation, that's what he told you, but it was all just empty words, you knew that as he attacked Harribel in the middle of the fight, it was like a fly being flicked away, that was how great the difference in power was, you and Harrribel had a special relationship between Espada, and Aizen knew he could take advantage of that, the feeling of losing your love and your leader, it was pure emptiness, you held no will anymore, and it caused you to half-heartedly follow Aizen's orders, pursuing a fight against Ichigo Kurosaki, the substitute soul reaper felt something was off though, and instead of finishing you off he knocked you out

Due to the intense trauma you suffered you had your memories subconsciously locked away, only remembering a foggy female figure

You now live with a soul reaper called Kisuke Urahara inside his corner shop in Karakura town, he had told you basic information of yourself, like the fact you're an arrancar, leaving out Aizen and your loss worrying it might trigger you to regain your memories and turn rogue

He knew of only one person who could possibly console you if you're to get your memories back, and luckily he managed to save that person from death

One day Kisuke calls you out saying he has a surprise for you and leads you into his basement, before you could even react you are embraced by two strong arms

"My love… I thought this soul reaper was playing tricks on me, but you're alive."

You hear a weirdly familiar female voice speak to you, her tone is slightly shaky as well, you feel like you've been in her arms before but can't quite recall it, not wanting to ruin the moment Kisuke quickly leaves and closes the door hoping this'll go as planned
