Seven heavenly sins

Every 150-160 years new pairs of sins and virtues are born. All the babies born in that decade will have a mark. 10 years after the decade is over 14 children will be chosen from that time period. The 14 kids were chosen because they were the ones that represented the sins/virtues the most. When they are chosen they are given special powers that represent the evil/good inside them. They each will be given an animal to represent their sin/virtue and also the opportunity to turn into their given animal. Each sin has an opposite, a virtue. The opposites are Pride/Humility; Gluttony/Temperance, Lust/Chasity, Envy/Kindness, Wrath/Patience, Sloth/Diligence and, Greed/Charity. Once they are chosen the virtues are sent to a camp to learn how to destroy their evil counterparts. The sins are usually thrown out as outcasts into the Pluto deserts. After 4 years of training the virtues are sent out to kill their opposites so the sins don't cause havoc for the world. Sunny was cursed with the sin, Wrath. Gray was gifted with the virtue, Patience. Both opposites of each other, what will they do? Will they destroy each other or work together to end this ancient feud? Who is it that wants to start a War for the ages?
