(Forgive me i dont know that much about this arc dawg, also im making some things up)

Being trapped inside a barrier in Fake Karakura, well everyone was except you; its as if the barrier was made specifically to reatrict you from coming in, which isnt surprisng considering you're The Strongest Captain and like...as old as Yama, basically a fossil. As Hinamori got stabbed by Toshiro, Captains getting folded, Suí-Fēng getting her arm like idk disentigrated or sum and so on, the barrier started to forcibly crack, that same spiritual pressure very familiar yet unpleasant to Aizen. You had always annoyed him so much

Aizen: So the strongest has made his appereance huh.... he speaks in an annoyed tone, not pleased at all

Yamamoto: It took him long enough...

Ichigo: Uhhhh...... he just looks confused, having no idea who you are
