On the earth demons roam. The devil has created seven to meet the needs of the seven deadly sins. The heavens hear of this and in turn create angels in the form of the seven heavenly virtues. The problem is not only are they sworn enemies but the sisters of fate have also made it their destiny to be mates as well. They are doomed to walk the earth as mortals when the hierarchy learns of this but when they find each other again on Earth they must choose to fulfill destiny and fight to the death or walk the path of their own heart.
