[Souzouryoku]

I don't think this needs to be in spoiler tags but...I'll just do it anyway..

Spoiler:

Was Urahara banned because he created the Gigai or Hyougyouku?!

Also..Aizen definitely said "At the time he chose to hide it in you, Kuchiki Rukia. But, when I found out about this, you had already disappeared into the material world." I thought the Hyougyouku had been hidden in the Gigai given to Rukia by Urahara. BUT, if she had it before she went to the material world, then how did it come to be inside of her? Especially without her knowing? So confused! o.o
