"Months have passed since Uoodo was consumed in fire. I've now wandered into civil war-torn Kummen. Mercenaries. Front lines. How appropriate for me. But now I know that she is here as well. It has to be her. But why?"

Chirico attempts to communicate with the pilot of the Blue AT, but his Marshdog is demolished and he is thrown clear. Kan Yu and his troops arrive, and the Blue At vanishes. later, Chirico reports his findings to Gon Nu - the pilot of the Blue AT is definitely a Perfect Soldier.

At the Fan tom Club, Coconna sings Chrico a love song she has written while Vanilla introduces some of the other mercenaries to him, Bully Kiderra and Pol Potaria. Quick action from Chirico saves the club from a guerrilla's attempt to plant a bomb, earning him the respect of the other men. That night, Chirico works on Gotho's personal computer to write a mission disc for his AT that will positively identify the maneuvers of a perfect Soldier.

The next morning, Chirico joins Potaria and Kiderra on a mission under Kan Yu's command; a supply boat needs an AT escort through guerrilla territory. Also joining them is the imposing Quentman, Ru Shako. They don't have to wait long for action - enemy Turtles launch an attack from the banks of the river, and Kan Yu's group quickly engages them. Chirico spots the Blue AT again and puts the mission disc to work. Their battle is short, but reveals much.

"My anti-PS program had worked. A little more work, and we'd be evenly matched. She must know it's me. But then why is she doing this?"

Chirico and Fyana travel the jungle together in his Marshydog, and when the two are ambushed by Veela ATs, three unexpected allies come to the rescue: Kiderra, Potaria, and Shako. Afterward, Chirico tells them what happened to Kan Yu and introduces Fyana, the PS they have been tracking all this time. Potaria and Kiderra agree to accompany them on their mission to assault Kanjelman's palace, but Shako dissents; he is bound by his contract with EX-10 and cannot bring himself to violate orders.

A short while later, an EX-10 helicopter passes overhead and spots the rogue mercenaries. Gon Nu relays the news to Rochina, who orders him to keep Chirico under observation. His actions could give them the opportunity they need to launch an all-out attack on the palace.

with Fyana's help, Chirico and the others destroy another platoon of Turtles and make their way closer to their objective. At the palace, Albert Killy informs Borough and Ypsilon that he is sending a new AT for Ypsilon to fight in now that his Snapping Turtle is gone.

Chirico's group reaches one of Kanjelman's arsenals. Fyana makes her way up to it alone and finds herself a Brutishdog. The others make short work of the installation. Fyana informs them of something she has overheard on the radio; that Kanjelman has ordered all Veela Guerrilla units back to the palace. Potaria is confused by this news, unable to figure out why the prince is abandoning his tactics after all this time.

Heading back into the jungle, Chrico and the others are spotted by another helicopter from EX-10, which is piloted by Vanilla. He reports that he has found Chirico, but is ordered to return to base. Chirico watches him leave and realizes that many eyes are now on him. His next move must be a decisive one.

"Go Nu wasn't going to let me go. As the enemy closed in from both sides, my excitement built. But in the palace beneath the gathering storm clouds, a deep whirlpool of suspicions was also building..."

High above planet Melkia, Albert Killy listens to Arron and Gurran, two scientists studying the PS, speculating on what must be happening in the civil war below.

Holding Borough at gunpoint, Chirico questions him. Ypsilon arrives, but cannot intervene. Borough explains that the Secret Society brought the PSs here to try and perfect them; their emotions have proven too erratic, and have constantly interfered with their efficiency as killing machines. What's more, they can never be remade into normal human beings. Kiderra attempts to attack Ypsilon from behind, but fails at the cost of his own life. His move disrupts the scene, giving Ypsilon the chance to attack Chirico. Fyana can only watch from her AT as the two grapple and fall from level to level down into the bottomless mineshaft.

Outside the palace, Gon Nu gives the order to move in. Behind them, a third party prepares to enter the fray: the Melkian army. Lead by Rochina, their orders are to overwhelm the palace and destroy everyone in their way. Only the PS Prototype is need alive. Unaware of this new development, Vanilla finds Potaria, who passes along the key given to him by Kanjelman.

Chirico and Ypsilon land at the bottom of the mineshaft, which is full of oil and priceless jijirium. Both their ATs have been damaged, so Ypsilon leaps out and challenges Chirico to a hand-to-hand fight. Fyana appears in her Brutishdog, and when Ypsilon refuses to stop, she fires on him. He is furious at her final betrayal, but the scene is broken by the laughter of Gon Nu. Peering down from above, he proclaims victory. Now that Chirico is of no further use. Gon Nu will destroy him along with everything else.

Rochina, however, has already begun bombing the palace from outside. Suddenly, Gon Nu himself has become expendable! Chirico and Fyana escape as the palace begins to crumble, and Ypsilon is left standing alone as Borough dies in the fire.

Chirico and Fyana find Vanilla, who gives them Potaria's key. It will activate an escape shuttle, and Vanilla wants them to flee in it. At the last moment, however, the insufferable Kan Yu appears and prepares to finish Chirico off once and for all. Shako intervenes, having finally decided his commanding officer isn't worth following any more.

Their enemies now dealt with, Chirico and Fyana launch in the shuttle, just in time to evade Melkian Scopedogs. They burst out of the palace and into the open air, their future opening up before them.

"My journey through Kummen was at an end. For my own sake, I had chosen to enter hell. For Fyana's sake, I was now leaving it behind. Love? could it be even I was capable of fighting for love?"
