User blog comment:CoolJazzman/Uryu "Last Living Quincy"?/@comment-2211792-20130629184533/@comment-8295743-20130629210031

Ryuken is no longer a Quincy because he has no powers anymore, he passed on those along to his son. He has Quincy blood, the same way Ichigo, Karin and Yuzu do, but without any abilities he is nothing more than human now. Although, the wording used in this chapter means Katagiri is either dead or powerless as well. This "Last Living Quincy" pretty much directly states the others are not alive. Otherwise, killing them would be as simple as finding their bodies in the Living World and destroying them. As to where they have been, search me. I can't imagine Quincy souls would be welcome in the Soul Society. So maybe that's it, maybe they spent the last thousand years hiding on Earth. Although, there is an argument for them hiding out in Hueco Mundo.
