A few weeks after the defeat of Kūgo and Xcution, the Wandenreich take over Hueco Mundo culminating in the advent of the Quincy Blood War. Uryū refuses to aid his friends in the matter by rejecting the offer of going to Hueco Mundo on the grounds that Quincys can do more harm than help. Later, Uryū is brought before Yhwach at Silbern with the other Sternritters and learns that he has been named the Wandenreich leader's heir. Ywhach proceeds to bestow Uryū with an 'A' Schrift in a private ceremony, making him a Sternritter while explaining to Uryū that he survived the effects of Auswählen compared to other impure Quincies due to an unforeseen power within him, thus, convincing Yhwach to appoint him as his successor. Despite learning that Auswählen is the cause of his mother's death, Uryū accompanies Yhwach to Soul Society for an invasion along with the Sternritters.
