t doesn't cause them to act against their will. They act of their own will in response to their perception, which by aid of Aizen's Souikegtsu are incorrect. Aizen does have to release his sword to shintai for it to be effective in this way, however, which is why the Gotei 13 are placing so much hope in Ichigo. He's the only one who hasn't seen Aizen's shintai and therefore the only one who can't be placed under total hypnosis at anytime. You only have to have seen it once for him to screw up your perceptions at anytime. Gin and Tousen are both acting of their free will, regardless. Whoever said Tousen truly believes that Aizen's way is the path of the least bloodshed is wrong though. Tousen's true motivation for becoming a Shinigami has nothing to do with that. I have yet to figure out what the deal is between Gin and Matsumoto, or what Gin's reasons are for following Aizen, or whether he will turn on him or not. Gin is a very interesting and complex character and pretty unpredictable. It doesn't really matter, though, because either way, Aizen views them as completely disposable.   See 15 other replies

I thought Aizen's hypnosis just affected the five senses. I never thought it can cause people to act against their will.   See 15 other replies

aizen's souikegetsu(dont mind the grammar) is as simple as just showing it and the person is completely hypnotized like hinamori, when it comes to strong people such as tosen and gin there more factors to such a thing. But i can assure you gin and tosen are acting out of free will.   See 15 other replies
