When Nagate finally emerges to the ship's surface, he enters a world where military service remains mandatory despite the passage of time since humanity's last encounter with an alien threat. His arrival coincides with the sudden reappearance of the Gauna, the alien race responsible for Earth's destruction. As humanity once again faces this existential threat, Nagate becomes involved in the ongoing conflict aboard the isolated vessel where the remnants of human civilization struggle to survive.
