There once were humans, then the monsters from beyond the horizon, the Spectrums, came and waged war against humans, then warriors of a new god, the Archangels, came and gave humanity the power to fight the Spectrums and so they did, some chosen humans, with the help of the Archangels mixed their genes with those of the monsters creating soldiers who could take on the Spectrums with ease.
Ages passed since the end of the war, now each Archangel rules over a continent and the world is with only a small number of Spectrums and at peace, making the existence of the hybrid soldiers seemingly useless, but there’s something else on the angel’s minds.
In this world a girl with a mysterious origin named Enid will bump into a ritual that would shatter the fleeting balance of the world.
