Watari and Kunugi are coming back to Nirai Kanai, with an Yamato Communcations reporter, Futagami. While coming to Terra is the Alpha Squad, who join with Elvy to take the place of her killed/wounded colleagues. Meanwhile, Futagami goes to Rikudo's place, to find information for Ayato. And when Alpha Squad and RahXephon attack a giant Dolem, it releases smaller dolems. And Ayato must defeat it and does.

A photographer heads out to a mysterious archeological site, but is promptly shot to death by the very woman who brought him there. At Nirai Kanai, Sayoko and Mokoto are getting together. Haruka is shocked when she walks by and sees him leaving. Helena, of the Barbem Foundation sends Doctors to investigate Quon, who is in a deep sleep. A new Dolem attacks, and both RahXephon and the Alpha Squad is sent out, but Ayato becomes distracted when he finds Quon inside RahXephon with him...

All that Ayato has known about his life proves to be a lie: his mother is not who he thought she was, his old friends are spies and Tokyo Jupiter is infested with Mu. The only person he can trust is his old school friend, Hiroko Asahina. Together they decide to escape the city for the real world

The aerial cities continue to multiply. Kunugi decides to evacuate everyone from the island and stay by himself to try to stop the D1 headed their way. TERRA leaves with everyone else. The D1 is the Dolem of Kuki, Kunugi's former superior officer that gave him the order to kill his own daughter. It reaches the island of Narai Kanai and starts destroying cities. Kunugi sends some missiles and remote control fighter jets, but they do no good. The D1 attacks the building he's in while Kuki taunts him. Kunugi is injured, and Kuki says it's over. But Kunugi tells him that the entertainment has yet to begin, and activates the barrier creating thing. The barrier destroys everything in it's path, including the cities, Kunugi, Kuki, and the D1. Ayato makes a choice to join with Ixtli in order to protect Haruka.
