Lionne in The Fake Saintess Doesn't Want to Save the World (yet to be introduced in uploaded chapters) would be facing charges for lèse-majesté and probably also assault and maybe treason (just for cursing and throwing a punch or something to that effect, but still). Not canon tho - at least as of now...
They don't like authority figures and have a long way to go in sorting out who exactly they are angry at all the time. Moreover, most of the authority figures in the story are trash, so really lionne's defense would be that the royal in question deserved it. And they would probably be right
