For people considered above everyone else based on class, if we can assume the world is like how the kids are portraying it, why aren't "Sword Saint" and "Magic King" nobility? Or, rather, why are they still "commoners" living in a village?
Perhaps there's no nobility infrastructure, but I can't believe that, since the obvious reverse-trap is wearing better clothing than the other children. I guess we'll find out more later, hopefully.
