In the 150th year of the Great War, rising imperial commander Reinhard von Lohengramm prepares to obliterate the Alliance fleet, but fears he is opposed by the "Hero of El-Facil," the illustrious Yang Wen-li.
Received back home as a war hero, Yang is granted command over the newly formed 13th fleet, while finding himself entangled in the Alliance's political disputes.
After his victory at Astarte, Von Lohengramm is promoted to imperial fleet admiral and reflects on the events in his youth that awakened his ambitions.
Von Lohengramm implements a scorched earth strategy to deplete the invading Alliance's resources, but the officer in command of the operation is troubled by his past.
