Just when Ayato thought he had finally learned the truth, the walls between the world of the Mu and our own "real" world begin to crumble once more. With the enigmatic Quon and Reika as guides, he must discover the truth of his own nature or be forever trapped inside a prison of his own dreams. Reality and fantasies intertwine in nightmarish rhythm, but the ultimate horror is yet to come as the fabric of time and space itself begins to unravel in the third volume of RahXephon!
