@kapodefrutilla @Summary
p sure that Elma has to return to her duties as a harmony faction dragon. Before, she could stay on earth under the purposes of 'monitoring tooru and iruru and keeping them in check'. Now that Kobayashi is a guardian, that reason is gone. And Elma, even as strong as she is, has a role to fill, just as she said. Strength alone doesn't cut it.
It's continuing from the Lucoa fight. Of course Lucoa is strong, she's more of a god than a dragon. She could probably take on most of either faction all on her own, but because of that she has to live a certain way. If you're not strong enough, strength doesn't matter, and even if you are, it doesn't mean everything works out as you like.
this is the kind of plot COOL tends to make.
