@AK true. Maybe Mashima can probably prolong the manga by introducing new villains. I was also actually thinking that maybe he could introduce new keys that are stronger than the gold ones. They could also be 12 that would represent the constellations from Uranometria. @WC I think that weird feeling will be tackled soon.
