I think Uryu is the last living Quincy because all members of Vandenreich are souls, not humans with living bodies. However... What about Ryuken? Could it be that he was killed off-screen? Also, remember how Ryuken said, "I am not suited to rule the Quincies" after he left Masaki at Urahara's shop? And now Yhwach plans for Uryu to become the next emperor. Was Ryuken supposed to be his successor initially?
