The Republic of San Magnolia fights a safe humane war using drones. In reality, however, the drones are piloted by humans called 86s, who are called “pigs” and considered less than human.

As Lena lives a life of safety and comfort inside the walls of her city, the 86ers fight a terrible battle against an unstoppable and inhuman enemy.

Lena finds herself growing closer to the Spearhead squadron, or so she thinks. But a deadly battle drastically changes her perspective.

After a brutal death, Lena comes to terms with her real status as an Alba, and what it means to force another to fight for your sake.

Lena learns the truth about the upcoming end of the war, and how the Legion is a much more deadly threat than she though.

Spearhead enjoys a brief respite near the cherry blossoms outside the wall, but a deadly attack brings the dangers of war even closer to home.

As the day of the festival arrives, Lena and Shin watch the fireworks and enjoy a brief respite from their battles.

Shin confronts his brother deep within Legion held territory. But even if he wins, there's no going back.

The crew of Spearhead has left on their final mission, never to return home. What awaits them outside the borders of their home?

Spearhead awakens to find themselves in a strange new land, while Lena continues her battles as a Handler.

The Legion's large-scale offensive begins, and the Spearhead crew are sent into the thick of the fighting. But even back at base, there's no safety to be found...

Nordlicht finds themselves up against a massive foe in the middle of enemy territory, with no hope of escape and no reinforcements coming to help.

The members of Nordlicht drop out one by one in the face of the Legion's onslaught, and Shin is left to face the Morpho alone.

At the end of it all and left behind once more, Shin is at the brink. Just then, someone appears, in a sea of red flowers...

The operation to destroy the Morpho was a success, and Shin and his team fulfilled their promise to return to the Federacy alive. After enjoying a brief respite, they once again wished to serve in frontline units, but they received a certain notice from Ernst. After crossing the deadly battlefields of the Republic, they arrived at a new meeting in the Federacy. They fight, suffer, and see a ray of hope. This is a story of boys and girls who have begun to move little by little. At the end of their journey, what is reflected in their eyes?
