In the chapter where Uryu was announced as the successor to the vandenreich, Askin Nakk Le Varr referred to Haschwalth as "next emperor". I wonder if it is possible that the sternritter might be planning some sort of coup d'etat. Maybe not specifically against Yhwach. But maybe against Ishida. Even Bazz-B said something to the effect of most of the sternritters being cool with Haschwalth being the successor. I definitely think there is something going on there. Is Haschwalth really loyal to Yhwach or is he planning to pull an Ichimaru Gin?
