What I want to know is: why was Ryuken unaffected by Auswählen? You could make the argument that he was a pure blood Quincy, but Masaki was a pure blood too. So it doesn't make sense that one would lose their power, but not the other. Perhaps Yhwach doesn't know about Ryuken, but he knew about Masaki, so that seems unlikely.
