Keith and Physis discover the shocking truth that they both were artificially created through a process of genetic manipulation and a product of many failed experiments. It becomes evident that Physis is not a Mu, but an artificially created human given powers by Soldier Blue in the past. Jomy returns to the amusement park where he was supposed to have undergo his adulthood exam by Terras #5 and completely destroys Terras #5 this time. Keith puts Mother Iliza and Educational Station E-1077 on a self-destruct sequence and a new computer system called Grandmother is reinstated. With Terras #5's computer system destroyed and the path to Terra cleared, Jomy decides to venture there along with the other Mu.

On the way to Terra the Mu encounter a large human army near Jupiter. War and bloodshed ensues with lives lost on both sides. The human army is equipped with special spacecrafts immune to the Mu's psionic powers and as a result three of the blue-type Mu are killed. Tony who was struck with grief unleashes a large psionic wave that pulverizes a large section of the human army. Keith then decides to use the Mu captured on Artemisia as hostages and this angers Tony even further.
