Despite the Humankind Empire Abh's dominance over the universe, not everyone is under its control. Four groups still remain free, and they've put aside the past differences between them by signing a treaty, the primary goal of which is to combat their common sworn enemy.
Unfortunately for Jinto Lin, one of the four independent nations, the United Mankind, has chosen this particular time to take aggressive action. His military career cannot start before his training does, however, and he is ordered off the ship as a noncombatant.
It is up to Lafiel to transport him to safety and warn the empire of the impending attack. The two manage to escape from the Abh ship before the United Mankind forces arrive, but what will become of the crew they've left behind to face seemingly insurmountable odds?
