Arron and Gurran monitor Ypsilon's emotional index from the Teltain. Now that he faces Chirico, his readings have levelled out to those of a proper killing machine. ypsilon and Chirico lunge at each other, and Fyana holds off the Tortoises, admonishing Chirico to rember that they're both fighting to live. He instructs her to get back inside and stand ready in the control room. Carefully, Chirico lures Ypsilon and his troops toward the engines of the crashed ship and leaps off the edge. Ypsilon follows - and Fyana activates the thrusters! Caught in the backblast, Ypsilon's Strikedog is smashed, and the invaders retreat.

Now convinced that a third, more aggressive party has joined the fight in the nonagression zone, Zanjeny and his staff order a task force into the area in support of their patrol fleet. On board Teltain, Ypsilon recovers from his injuries and thinks of his next battle with Chirico.

Knowing Ypsilon will be back, Chirico tampers with the verniers on the now-silent hull of Battleship X and finally realizes what planet he is on: Sunsa, the site of the bloodiest battle of the Hundred Years War...a battle he himself has remembered in nightmares. An AT landing craft appears, and Chirico and Fyana rush to the control room as it lands on the hull. Out steps Ypsilon in another Strikedog, with more Tortoises backing him up. One by one, the verniers blast away at them.

Ypsilon reports this setback to Futtor on the Teltain, who suddenly has to face a problem of his own - Balarant ships approach, and he has no AT platoon to fight them off! Forced to tip his hand, Futtor goes on the offensive, and a devastating battle erupts in space! Having found their way inside Battleship X, Ypsilon and his remaining men reach the empty control room, and discover that Chirico has set the entire ship to self-destruct! They escape just in time, and launch as the vessel rips itself apart.

chirico and Fyana has also gotten away, loading a transport truck with ATs and driving deep into the Sunsa desert. There, others await them...

"Would we ever have any peace? I felt like screaming. If there was a God on this world, he was a cruel one. Too cruel. This planet's name is Sunsa. And I know it holds no welcome for me at all..."

On the Teltain, Futtor insists that they must leave Sunsa now that Ypsilon has been recovered. Arron and Gurran reply that their mission take precedent. Ypsilon must be allowed to fight Chirico again, and they must stay to observe.

On Rochina's ship, Chirico fine-tunes a Scopedog and writes himself a new mission disc containing everything he knows about the maneuvers of a PS. Fyana speaks with Chirico, admitting she is afraid for him, but he counsels her to accept what must happen. Ypsilon is fighting out of loneliness, and will not stop until one of the tem is dead. Ypsilon, meanwhile, renews himself with a jijirium bath and launches for the surface in a new Strikedog.

On the other side of the galaxy, Melkian General Karmeny meets with Battentain to discuss the implications of what has happened in the Nonaggression Zone. Battentain is shocked to learn of Rochina's defection, and admits he never quite knew how to read the man. Despite the risk to the peace treaty, a task force of Gilgamesh battleships must be sent to Sunsa with Rochina as their target.

Chirico crosses the Sunsa desert to Siguray Crater, where Ypsilon's empty landing craft stands waiting. Chirico takes the bait, and the battle is joined! This time there are no distractions; the two clash with each other time and again. Chirico's mission disc works perfectly, allowing him to match Ypsilon move for move. Rochina takes notice and finally announces to Fyana what he has suspected all along: that Chirico is a true Perfect Soldier! And at long last, Chrico fires the fatal shot that takes Ypsilon down!

Before he can finish Ypsilon off, however, Chirico is interrupted by Fyana, who gives him the shock of his life - that he is more than human. Chirico insists that his mission disc is what allowed him to win, but then notices that the disc burned itself out only a few minutes into the fight. From then on, it was his own ability. Ypsilon insists in his final moments that Chirico has to be a PS...Ypsilon's pride would not allow him to die at the hands of a normal man.

Later, Chirico prepares to leave Sunsa, Rochina's words echoing through his mind: "You are a PS. You want proof? Then go to planet Quent. There you will learn everything."

"What was it that lay hidden in my past? I'd fought Ypsilon and won. But I couldn't believe it. There was no way I could be a PS. The Planet Quent...what awaited me there?"

Killy watches from his ship as the Gilgamesh fleet approaches Quent, where Rochina's Balarant fleet awaits them. Arron and Gurran report from the surface that they are safe, but their entire AT army was destroyed. Killy is content to wait and watch history repeat itself now that the power of Quent is reawakening.

Admiral Lepard speaks with General Battentain, who warns him about what he is walking into. Someone has been tampering with the secrets of this planet, perhaps even the lost Perfect Soldier.

Arron and Gurran watch as Lepard lands and is greeted by Rochina. The two officers begin their verbal fencing, Lepard demanding that the Prototype be returned. Rochina attempts subterfuge, but when Gotho, Vanilla, and Coconna appear, his lies about losing contact with Chirico and the Prototype are revealed. Recovering, he offers to rendezvous in orbit and bring the Prototype with him. Everyone who watches the proceedings know what a risk this will be...especially with Chirico involved.

Chirico infiltrates Rochina's AT platoon, and the Balarant fleet lifts off into space to play its part in the deadly game. Rochina's landing party docks with Lepard's ship, and he produces Fyana, insisting that the Gilgamesh now leave Quent. Lepard refuses, but as a Scopedog steps forward to seize Fyana, Chirico makes his move, striking out from inside a Balarant Fatty. Rochina escapes with Fyana, and the Battle quickly escalates into an all-out bloodbath!

Chirico takes a moment to free Gotho and the others, then escapes outside into the escalating firefight.

"The battling had turned more intense than I expected. And then somewhere in my body, I felt it. A premonition. Yes, one from the darkness, for only me to know. And that's when the whole horrible thing happened..."

Having lost all contact with the Scopedogs chasing Chirico, the combined fleet consider their final option; that of destroying Quent itself.

Chirico smashes the last of his pursuers and nearly collapses from the effort. Finally, Fyana appears in her Berserga and asks him one last time to turn back. He refuses, firing on her and throwing her backward into a teleport field. She is gone. Wiseman congratulates him, and beckons him on by foot.

Chirico struggles to reach the final goal, the central core of the Wiseman bio-computer, the collective consciousness of the Overmen. Chirico lies unable to move, and Wiseman lowers a large machine toward him, one that will complete the bond between God and successor. All Chirico has to do now is stand up...but instead he plays his final gambit, firing a bulled directly into the machine!

At last, Chirico's subterfuge is revealed - having come this far and lead all of his enemies into their own death, he now sets about the work of destroying Wiseman itself. Wiseman pleads with him to stop, explaining that it was he who brought Chirico together with Fyana, and provided her name. This gave Chirico something further to live for, and with life came the desire for strength and power. Wiseman also explains that Chirico need not regret the death and violence he has dealt in the battlefield, saying that "God does not sin when he kills."

Chirico ignores every word, continuing to disable the computer core. As Wiseman's consciousness begins to disintegrate, it lashes out one last time, throwing Chirico to the ground with an electric shock. He rises to see Rochina standing over him. Rochina tries to stop Chirico's sabotage, but Fyana leaps in to overpower him. She recognized his true intentions when he fired only to damage her AT. Together, the two complete the work of killing God and flee to safety as Rochina screams in anger and dispair and what he has lost.

The combined fleets of the Gilgamesh and the Balarant stand witness as Quent explodes with the fury of a sun.

Epilogue: One Year Later

A stolen shuttlecraft soars away from a Gilgamesh planet as a new war dawns on the horizon. Sometime later, a tiny capsule is released into space. Inside this capsule, preparing to disappear into history, Chirico holds Fyana dnd bids farewell to his Friends as they drift off in search of a world untouched by war.

"Coconna. Gotho. Vanilla. Shako. I'm glad I was able to meet all of you. And you, Fyana..."

Decades ago, two people took drastic measures to ensure their escape from a galaxy engulfed by war. Unfortunately, the past has finally caught up to them.

Cardinal Montwell uses a recent accomplishment as leverage. Titania seeks out someone intimately familiar with Chirico’s history.

The deliberations take a shocking turn with the delivery of unexpected news. Titania finally comes face to face with Fyana.

Chirico is coming for Fyana and woe be to anyone who stands in the way. The final confrontation between Chirico and Titania is approaching. Who will be left standing?
