So not only is the summoned hero a massive cunt, but the third princess is an even bigger cunt. Good to know.
I would love to hear why she thinks she has the authority to order around foreigners and expect them to obey her, when they're visiting with valid visas. White Flame and MC aren't her subjects, she has no actual authority over them. They are technically standing on her land, though even then it's not hers, but her fathers, so the worst thing she could do if they are guilty of no crimes is order them to leave the country immediately. She can't "take command" of them. If this was most manga, I doubt that facet would even be brought up, but with this MC in particular, we might actually get to hear him ask why he's obliged to obey her.
