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.

A large attack force is sent to Earth, the first wave in a new campaign to reclaim the planet from the Blue. Yuji is awed when a fellow Sleeper, Tony, wipes out an entire Blue nest on his own. Yuji determines to be the best, at any cost. But is this unhealthy obsession with beating Tony really a symptom of a much greater problem?

The Sleeper Brigades launch yet another offensive against the Blue, and Yuji's lust for battle grows out of control as his B cells begin to take hold of his sanity. Meanwhile, a mutiny has begun on Second Earth, and Marlene finds herself with an integral part to play in the plan to overthrow the High Council. But Marlene has her own reasons for aiding Seno Miyagi?

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.

Yuji, a high school teenager, discovers that he has an incurable new virus. With life looking very bleak, he's left only one option: hope that the future may hold a cure. With his decision made, he opts to undergo artificial hibernation... Two decades later, the world has become a place where human beings are hunted down by giant insect-like creatures called the Blue. Yuji must now not only for his own survival, but for that of the entire human race!

It is unknown how long they have existed. Some sightings date back to 2017. But in the year 2031 Humankind was replaced as the dominant species on Earth. Suddenly awakened after 22 years in suspended animation, Yuji Kaido finds himself thrust into a nightmarish reality. Yuji soon learns that the very survival of the entire human race rests in his hands.
