Only Magic Here

So basically humanity is basically cooked by a random alien visit, now everyone is practically a magic-girl sleeping beauty combination with a singular very powerful magic (anything you can think of) and the world had basically been replaced by the aliens that visited and are now humanity's replacement. The aliens call themselves the Kun, who are basically humans with red eyes and magic. Oh right, now awakened humans that somehow awake are now their natural predators as you will have a tugging urge to slay em all! (heck you can even awaken as a magical teapot and you will probably still be able to demolish the Kun) Everything else will (probably) be answered by a Kun *shrugs*
