There was a war that broke out between Heaven and Hell, and because of this war Angels and Demons are now widely known, as well as many other supernatural creatures. The one thing that could end the war was the Valen Aes, a sword so powerful that God himself had to sacrifice his life, along with a human's, in order to create it. With this sword the Angels sent the demons back to hell. But the sword was too powerful to keep in Heaven, and it would be destructive if it fell into the wrong hands, so the sword was given to the humans to hide. Before God sacrificed himself, he created a void within every human soul to hide a weapon that only Angels have access too, except for one soul that would hold the Valens Aes. Yet every 100 years the soul and sword would return to heaven in case the Angels needed it, but for the past 2000 years they did not. Our story takes place during the 20th reincarnation. The holder of the Valens Aes is Gabriel O'Conner, and the demons know. With the help of his guardian angel, Alexander Cassiel, and many other Angels, they manage to hide Gabe and keep him safe. But it wouldn't last forever.
