As the Mu launch a succession of attacks against the free world, TERRA is forced to use their secret weapon, the RahXephon, despite the reluctance of its pilot.
Lost in time and trapped in a world he thought had been destroyed, Ayato must confront both a new wave of Dolem and his suspicions that he is only a pawn in a much larger game. The mysterious advances of the girl known as Quon and the reappearance of a supposedly dead friend are only a few of the many mysteries that must be unraveled.
