Demon Days

Heaven and Hell are on the brink of war, and the Angels are practice-fighting the demons. They are paired together by God and Satain, they pair them by strength, speed, capability, and rank. When a Satain's grandson battles with God's Granddaughter, they are perfectly matched. They soon swoon for eachother, though it was not what they intended, and little do they know is that the battle can be stopped only by them. But do they want to stop it?
