At the edge of the universe, the war between humanity and star beasts has raged for a thousand years. Star beasts, humanity's natural enemies born from the universe to purge its greed, live by devouring civilizations. Humanity has built defenses with technology and military might, but has never been able to break this cycle of life and death, so it has begun forbidden research.
An escaped test subject accidentally ends up as a military academy student, where they meet teammates carrying secrets and are forced into a conspiracy. They discover that the conspiracy behind the forbidden experiments goes far beyond creating super soldiers. Even the war from a thousand years ago is closely connected to a plan called "Pandora."
This is a showdown of deliciousness and violence, a symbiotic experiment spanning species, and a journey to find oneself and save the universe.
