An end to the endless war. The possibility of stopping the Legion once and for all. Such is humanity's most fervent desire. But in the war-free world of tomorrow, what will become of the Eighty-Six?

Many have gained a renewed hope for the future. Some have found love, and others have new aspirations, but what of those who have yet to dream? The warm rays of hope have bent their iron wills and distorted their realities. For those tragic few, the worst is yet to come...

The Republic's evacuation resulted in massive casualties on both sides, and the fallout takes a toll on everyone. As Shin muses on what it means to be a leader, Lena thinks of her homeland, now lost to her forever. Frederica, too, is dismayed by her own powerlessness as the ill-fated Empire's last Empress—she'll have to change if she wants to survive. Meanwhile, discontent is brewing within the Empire, and a few disaffected squadrons, desperate to reverse the state of the war, reach for a dangerous miracle...?

The Spearhead Squadron has sustained heavy losses in the battle against the new Morpho. Among the dead is Shana, Shiden's-Vice Captain.

An unprecedented electromagnetic attack from the Legion rocks both Giad and San Magnolia to their very foundations. With the Gran Mur destroyed, nothing stands between the Legion and the unguarded Alba enjoying the height of luxury in the capital. Having no other option, the Federal Republic of Giad orders a special operation. But will Shin be able to take the fight to the mechanical menace while also battling his personal demons...?

Live to fight. Die with honor. That was all they knew, and they were proud. But as they saw themselves reflected in the Sirins-slaughtered by the thousands with nothing to show for it-a crack formed in their ironclad resolve. Shin's mind festered with doubt. Lena's heart tore at the seams as she struggled to understand him. Would they find common ground over the course of the United Kingdom operation? Or would they drift further apart...?

Long besieged by the fully autonomous killing machines known as the Legion, the Republic of San Magnolia endeavors to turn the tide of war by employing autonomous weapons of their own... Enjoy Asato-Asato's award winning novel in fully illustrated manga form!

The San Magnolia Republic has long been under attack by unmanned weapons from the neighboring Empire. Against this onslaught, the Republic has also deployed similar weapons, narrowly avoiding great loss of life and impending disaster-or at least that's how it seemed. The truth is that it has never been possible to have no casualties. Young men and women drawn from the Republic's supposedly non-existent 86th district are organized into the "86 unit" and then ordered to pilot the "unmanned weapons" before heading to battle

Following Kaie's death, Lena becomes distinctly aware of both her own ignorance and the fierce emotions the Eighty-Six hold toward Albans like her. As Spearhead squadron sorties again, she hears it-the voices of the dead, mixed in with the mechanical cries of the Legion, and Kaie's among them...!

Lena takes command of the front-line Spearhead squadron from her post within San Magnolia's fortified first district. She and Shin fight on without ever seeing one another, but the fate of the two takes a sudden turn due to a death on the battlefield...

A collective sigh of relief is exhaled as Lena, Shin, and the others enjoy a hard-won peace. But no true member of the Spearhead squadron can avoid battle forever, and these few survivors welcome it. They willingly walk back through the gates of hell, ready to resume the fight against the Legion, emboldened by full hearts, fresh perspectives, and...a new friend.
