We meet again.
I believe the kingdom as it is understands most that of they were to do anything to chain her, even with words, the demon kingdom would be in so deep into their buttholes they'd cough up furballs. So right now they are giving her the highest title they can give her without being liable to said chain.
Yes, there are some who are dubious enough to not give a shit- we've already seen that. But at the same time, she's already been through it and won't likely fall for it again. And even if she does happen to get caught up in another scheme, she knows not to swear any oaths. But, external happenstance may cause this reasoning to go awry.
I doubt even that one kingdom with the Prick for a king will try anything again for fear of what will be done to them. Honestly, the only people dumb enough to try anything is the church, but only because they don't know of her higher authority and because it's the church. Them bitches always be trippin'.

R I dont think the kingdom is dumb enough to try and hold her, because demons.
