Vanderreich Fear The Bankai.
There is a reason , why Vanderreich are sealing the Bankai.
But they cant seal Ichigos bankai = not even the Sternritter was able to.
Now , Ichigo weakened the vanderreich = With ease.
And Now Urahara comes to Hueco Mundo = And "One Hits" the vanderreich.
Ichigos Job in Hueco Mundo is done now = Now they head for Soul Society.
Also , Ichigos bankai = Cant be sealed.
Maybe because , hes Zanpakuto consists of Hollow and Shinigami powers.
Also , it could be possible , that Ishidas father is Ichigos Uncle.
I think , that Ichigos mother was a Quincy.
Maybe that's why Ichigos reiatsu is the color blue for some reason.
