For thousands of years, the church of Arzmania, used light magic called Paradis, to protect the people against, devils called Fyona. The church, was on the brink of extinction, causing them to hold a peace treaty, with the Fyona Kings and Queens. By that time the church, started to secretly raise an elite force of female knights, called Archangels. The Fyona Kings already knowing the church's plans, curses the Archangels, to fall in love with their sons. Due to the curse, Sarin, the next-gen of Archangels, seems to be the most promising and top, Archangel, until she is suspected of being cursed.
