Two teenage girls, friends, find a strange book in the library. With a beautiful leather cover and illustrations. There is only one catch with this book. When you read it you get dragged into it. First one is dragged in and meets a bunch of odd characters.
There is a prophecy and they are pulled one to a side of it. With a cast of characters to go with each side of the prophecy, the girls learn about the world they are in and the history that makes the culture tick.
This is a series that is at first a bit silly, like a lot of animes, but as the story evolves the story becomes richer and a little confusing but you are drawn in and you definitely want to watch it.
