What if, during the final fight of the Winter War between Ichigo and Aizen, Ichigo gets Isekaied, and Aizen is dragged along with him? I’ve never felt like Ichigo had any personal dislike over Aizen and just responded to the threat he posed to himself, his friends, and his family. Aizen isn't the sort to go on a rampage for no reason, especially in a world where such actions would have no benefits. Thus an uneasy truce between the two is formed though Ichigo doesn't trust Aizen not to try something like taking over this new world and stabbing Ichigo in the back so he can't stand in his way so Ichigo keeps a close eye on Aizen.
I’m not sure whether I like the idea of these two having all the powers they had before or being dragged down to Level 1 and forced to learn the rules and powers in this world. Both have potential and I think it would be really interesting to see an Aizen completely stripped of his Godlike power and be forced to use his natural physical strength and intelligence without the Reiatsu to boost him further.
I think Ichigo would be focused on returning home as soon as possible either way because, with the way they left, he’d be uncertain about the health and safety of those he cares about. However, he’s also aware that he needs to keep an eye on Aizen to make sure he doesn't try anything in this new world when it is in a time of turmoil, especially as Aizen is a master manipulator and the people in this new world don't know to be wary of him and if Ichigo tried to explain it would become Aizen’s word against his.
