Celestial Beasts

In this world,there are 4 cardinal governors who have full control over their area.These governors own the strongest type of spirit,the Celestial Animals.In the past,exactly 100 years ago the Owner of the White Tiger leaped time into the distant future and killed himself and everyone else while doing it and the blame was put apon the Exotics. Because the Exotics were blamed for killing most of the world's population and most importantly the 4 Celestial Beasts they are treated as dirt and the current Celestials do nothing to stop the mistreatment even while knowing the truth.Well,this is where a kid named Sento,owner of the Cat Spirit,has decided to end all the prejudice even if it means he has to get his hands dirty and lose the respect of his people to accomplish it.
