The two countries were fighting for a "saint" with only 10 people in the world. "Saint" is an existence that exercises super -normal power and causes miracles. Whether or not the "sacred" can be earned ahead of the enemy country determines the fate of the nation. The girl Mary, a "magician" who is considered the strongest of the "Empire" and is an assassin who has the nickname of "Reaper", is told that he should be able to play his life.
