So I was just wondering what do you guys think about the Asauchi. Im referring to them not being physical manifestations. When Ichigo said they were the physical manifestations I thought spot on ichigo but then oetsu says "so close no there not really manifestations but that will do for now". Well what are they really what do you guys think, and also why does none of the zero division have their zanpakuto's on their person. I have not seen any of them with a zanpakuto. So I would like to hear you guys thoughts about these things.
