Sousei no Onmyouji

This is the story about two kids, Rokuro and Benio, and their lives as onmyouji warriors.

Rokuro is from a family of exorcists who remove the evil Kegare, but his real dream is to be a singer, a soccer player, or anything other than an exorcist. When another exorcist, a girl named Benio arrives, Rokura is suddenly inflamed with competitive spirit and decides to put his natural knack to good use. Their rivalry gets more complicated when they both learn they are the destined "Twin Star Exorcists," two ultimate fighters fated to marry and create the prophesied child who will eliminate all the Kegare in the world.
