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.

Yuji is seperated from Marlene and Dice amidst the confusion of a sandstorm. He is rescued from the desert by a band of nomads, and is befriended by Elena, a young nomad girl. As Yuji begins to believe that a peacefull life might still be possible, a raid by a group of bandits serves him a harsh reminder that there is more than one kind of danger in the world -- and it is never far away.

Marlene and Dice are reunited with Yuji outside the nomad camp. Marlene pressures Yuji to continue his journey to Second Earth, but Yuji refuses. He decides to remain Elena and her people and to live out the rest of his life in peace. But when Marlene and Dice are attacked by the Blue, Yuji is forced to choose between his life with Elena and saving the lives of his friends.

Satelite images of the Earth reveals a mass Blue migration in South America and Yuji volunteers to investigate. Once on the surface, he and his team discover that the Blue have mysteriously vanished without a trace. Now, the only hope Yuji has of finding answers, lies deep underground in the dark tunnels below a massive Blue nest.

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.
