Ayato Kamina, a Tokyo high school student, witnesses an attack in the sky by a huge floating machine. In the ensuing chaos, he and the mysterious Reika Mishima find their way to an ancient shrine, where Reika awakens the giant, winged robot RahXephon from inside an enormous egg.

He is enlisted by Haruka Shitow, a feisty special agent, to help in the fight against the Murians - but what has become of Reika Mishima? Why does Ayato's mother bleed blue blood? What is the purpose of the Mu civilization? <br />
