Part One

Anna and Amanda are twins who can sense positive and negitive energy. Their father works as a demon exersist and they usually end up helping him. However, when they move to Japan to help cure a local demon problem, they bite off more than they could chew. Things get worse when a demon lord joins the girl's school, then tries to kill them and take their guardian weapons. Will they be able to survive and save Japan, then the world, or will Eros and Demos be lost?
