Everyone passed the test easily, but there's an even more important event happening than everyone's entrance exam.
Back to two years ago, after the kingdom stopped several Stampedes that happened around the same time, Albert has prepared many things so he can report this to the other kingdoms.
Back when after Roy and the others just saved Candy as they are trying to kill every cult member who tried to attack Angela for trying to breakthrough, they found out from interrogating the twins they interrogated that in a city in another kingdom, kingdom Arturo, there's a recruitment for joining the cult. After hearing that report, Albert decisively sent out some of his trusted agents to spy on said kingdom.
The result was… they found nothing. The cult hides their existence well in that kingdom, and probably hides even better than the cultist in other countries. And that only makes Albert feel suspicious.
