uryuu ishida

We all know that Kubo said that this arc will be large, and therefore it doesn't seem reasonable for it to end any time soon, despite how far Yhwach has gone by now. It seems the war is far, far from over, the real war with mixed alliances (Quincy/Shinigami) has only just started~ This...

So... Do you think Uryu is powerful enough to become a Stern Ritter, not a Jagdarme or a regular Soldat? Which letter will he receive? What would be his special power?
