Mayuri! Mayuri! Mayuri! Nice one again kubo! Now again we are sure urahara is Mayuris eternal boss. Kurosutchi mayuri gets to control the dead arrancar while urahara kisuke gets to subjugate the living arrancar. We all know mayuri would have also been able to deal with aizen one on one if not for his zanpakuto kyogasuigetsu.Won't be surprised if we find out that he was the one who put mayuri in the dungeons.
