'Somethings there, are still the same like Urahara being on the human world because of banishment, well, Aizen died though. Apparently, He met ywach when he was amassing his army in hueco mundo. They fought, the result was both died almost all their people died except some characters like Ulqiora and Grimmjaw still being alive but not a villain. The first one became like a leader figure while the latter became a real battle maniac, always looking for a fight.'
