Oh wow. So many hate for the magician lady. Sure she reported the case to the king, sure she hates demons to the extent of complete annihilation, but at least she is smart enough not to blatantly follow her ideology. She is willing to work with MC, who is harboring a demon, in the last accident. She also calm enough to just leave the party instead of forcing the hero party to kill the demons.
All im saying is there is still hope for this magician lady.
