    Changing Amu’s life is going to take more than wishes and dreams–it’s going to take a little magic! One morning, Amu finds a surprise in her bed: three strange little eggs. Each egg contains a Guardian Character, an angel-like being who can give her the power to be someone new. With the help of her Guardian Characters, Amu is about to discover that her true self is even more amazing than she ever dreamed.

    Horrible nightmares are the only hints at the violent life she once led, but her past is about to catch up with her and awaken the merciless warrior within. Chiropterans -- powerful shape-changing creatures who need and crave blood -- threaten humanity once more, and a mysterious organization called the Red Shield needs Saya's deadly sword skills and mysterious powers to aid in the fight against these beasts. As her submerged abilities begin to reawaken and as she seeks to regain her memories, Chiropteran warriors are guided by a mysterious leader to threaten Saya and her loved ones. Asuka Katsura's manga series successfully expands upon the original Production I.G./Aniplex feature, delivering moments of jarring violence and thrilling action in a tale that spans several centuries.
