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 thought.

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.

Spearhead is given orders to undertake a pointless march into enemy territory, and not to stop until they're dead. Lena tries her best to stop this suicide mission from happening.

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 Squadron comes to the end of their long road, and a new journey begins for Lena...

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

The members of Spearhead are given a brief respite from the war. But is it alright for them to enjoy themselves when so many have fallen?

The crew of Spearhead find themselves back on the battlefield, as the tide of the war turns against the Federacy.

The members of Spearhead are reunited as a massive Legion offensive looms. With the next deadly phase of the war almost here, how will they spend their remaining hours?

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...

As the war with the Legion rages on, the enemy makes a final march towards the Republic of San Magnolia. Lena waits to stop them, but...

The team prepares for a final suicide mission against "Morpho," a massive railgun Legion capable of single-handedly turning the tide of the battle.

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.

Deep in enemy territory, with supplies running low and damage piling up, Nordlicht makes a final desperate march towards Morpho.

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.

Shin is blown clear of the blast and falls unconscious, where he has a vivid nightmare where he tries to grapple with his loss of purpose and survivor's guilt. When he regains consciousness, he sees a Legion unit approaching him with the intent to harvest his brain, but he is saved when Lena intervenes.

Shin and his friends and Frederica return to Ernst's home to celebrate their second Night of the Holy Birth holiday. Shin visits Eugene's grave and apologizes for being unable to save him, but tells him he has a newfound purpose to live and promises to return to tell him about the things he's seen.
