Uryu's Mother Kanae survived Auswählen as well, though the strain on her already fragile body was such that she passed away in the immediate aftermath. As seems to be in the same state as Kanae, and the fact that Yhwach acknowledged Uryu as his potential successor because he survived Auswählen clearly shows his interest in the survivors. Uryu was perhaps the only Gemischt Quincy who remained totally unaffected by Auswählen.
