Kira and Mu chase after Rau inside an abandoned building. The building was the Mendel colony’s generic research laboratory. Rau, Mu, and Kira engage in a gunfight. As if to break the tension, Rau begins to reveal a shocking truth.
Around the same time, Yzak is reunited after a long time with Dearka who went MIA in Earth. While pointing guns at each other, Yzak interrogates Dearka’s real intention.
Outside the colony, Natarle is strongly persuaded by Azrael, and the Dominion is about to resume battle against the Archangel.
During the firefight, Rau reveals about the experiments done in the laboratory to create Coordinators in an artificial womb. He says that Kira’s real parents were researchers, and he is the only successful example. Rau also reveals the fated bond between him and Mu… that he carries the gene of Mu’s father and says that he is his “defective” clone. Kira and Mu cannot hide their shock at the fact. “I have the right to pass judgment on humanity!” Rau cries out, and runs away.
As Rau returns to the flagship Vesalius, he entrusts Flay with a disk and sends her back to the Earth Alliance Forces…saying that it is the “final door” to end the war…
