In the 2030s Earth has been overrun by the Blue, which are mutated insect-like creatures that kill and harvest humans for food. Most of the surviving human race has moved to Second Earth, a huge spaceship that orbits the planet. Yuji and Marlene must work together to reach Second Earth and fight against the Blue.
Seasons & Episode
Still en route to Baikonur, Marlene and Yuji cross paths with a rough mannered stranger named Dice. With the Blue lurking dangerously close, he offers them shelter for the night and Yuji is given a glimpse into his seemingly carefree life. But as Yuji soon discovers, no one left on Earth is without their demons...not even Dice.
Marlene and Yuji arrive at Baikonur, only to find the space base in the state of chaos. The facility is crawling with Blue, and the computer defense systems have turned on thier human counterparts. Now, with supplies and personnel dwindling, the assembled recovery teams must launch a desperate bid to regain control of the base.
When Yuji disappears from the Medical Station, Marlene defies orders and decides to find him on her own. Now, with Amick Hendar's security forces on high alert, Marlene must descend into the lower reaches of the Military Station to find the one man who may know Yuji's whereabouts -- Science Director, Seno Miyagi.
Marlene notices that Yuji's behavior is getting stranger and stranger. On the battlefield he is a force to be reckoned with, but he has an unhealthy obsession with destroying the Blue. Has Yuji turned into something that he once despised -- a cold-blooded killer?
Director Miyagi reveals to Marlene the true cause of Yuji's accelerated rate of achievement -- an infestation of ""B cells"" that have begun to eat away at his mind. And unless she can do something to stop it, Yuji's sanity will soon slip away completely.
While Marlene flies a distraught Yuji back to Second Earth. Tony uses his Sleeper skills to infiltrate the High Council. The sky is turned into the newest battleground for survival. Only this time, the Blue have mutated into something unthinkable…
With Rick injured too severely to continue, Marlene and Yuji continue through the Medical Station alone. They arrive at the main computer room to find Tony waiting for them. Now Yuji must confront his one time friend and rival, and the only way to stop him is to kill.
A monstrous Blue has emerged in the heart of the South American nest, the only thing standing between Yuji and the answers he so desperately seeks. Unless Yuji wins this battle, all hope for the future is lost -- for him, for Marlene and for the entire human race.
