But Ulquiorra's reiatsu was shown to be different than others. Ishida exlained that it wasn't like reiatsu at all but rather like a giant suffocating sea. None of the other shinigami noticed anything such in Stark or the rest. As stupid and predictable as it sounds, I'm sure we're meant to believe that Ulqiorra is infact stronger than the top three (or four)
