Modern day humanity finds itself besieged by otherworldly horrors akin to ancient mythological entities such demons, lizardmen and many more. The world's military powers are taken by surprise, not only by the unbridled ferocity of the attacks but also by the little effect even the most modern weapons have against these beings. A band of three highscool friends find themselves as sole survivors in their general area and now must find a way to safety. Perhaps concieted in the true nature of these attackers there's something about human nature as well, while their forms are hard to comprehend  the abilities they use, the way they manipulate the elements is somehow intuitive to us, was humanity perhaps once capable of such feats of power?
