User blog comment:CoolJazzman/Uryu "Last Living Quincy"?/@comment-2211792-20130629184533/@comment-6904925-20130629201827

If you look at it Yhwach probably has caused the death of more Quincies than the Soul Reapers have and they tried to wipe them out.

As for Ryuken, that's real strange indeed, I wondering why, maybe due to the fact that he declines his Quincy heritage or he has lost his powers, or maybe Uryu has grown a lot stronger.
