User blog comment:Theraven22/bankai's that should be revealed/@comment-1774413-20100330203312

yeah i know that, but i thought the seeing the shikai part was neccesary to fall under the illusion and the shikai worked by manipulating the mind to control the other senses. i mean if aizen controlled sight, that wouldnt help him in making a person smell what he wanted them to smell, and thus he could only trick his sight.
