Why the fuck are they even still in the kingdom? They don't trust them at all and they made them slaves. Now that they've got their freedom what the hell is even keeping them there? Why cooperate with them at all? Why not just go to the demon kingdom since they are friends with the new demon king?
"You shouldn't have pulled a knife on the king after he tried to kill you, it's going to make cooperating with the kingdom that made us slaves even harder " Oh fuck off, fuck this retarded author.
