Mellowlink is on the run as he tries to assassinate the first of his prey.

Mellowlink fights in an AT Battling arena, where his next target is considered "the best" AT pilot there is, and known for squeezing to death all those who lose to him.

Mellowlink's next target is a Major who has carved out a life for himself as a rich man in the Kingdom of Kummen. While relishing a rare chance to hunt down Veela Guerrillas on his land, Mellowlink comes upon him mid-attack, and proves to be more than the Major bargained for.

Mellowlink is trapped aboard a crashed ship, as he duels his next target to the death. This time however, it's him who is cornered.

Mellowlink's motorcycle breaks down while traveling between locations. As he waits out a passing acid-rain storm, he dreams of the deaths of his comrades, and how his endeavor for revenge began.

Mellowlink is locked up in a prison where his next target is the warden. Beset by both the other prisoners and the warden's interrogations, he bides his time as he awaits Lulucy to arrive, with her performing troupe, to give him his gun in secret.

Mellowlink stows away on a train headed deep into wilderness territory where Bandits are prone to attack.

Mellowlink and Lulucy flee the train after being discovered by border guards and become trapped in the ghost town of Kerama City.

Mellowlink fights to kill his next target and to rescue Lulucy, who has turned out be of Nobility. What's more, he is fighting at her castle.

Mellowlink's final showdown with Major Boil.

Mellowlink travels to the base where Helumesion is the commander. Lt. Cardine's true agenda is revealed.

Initially hunted down by the base's guards, Mellowlink is able to escape with Lulucy when it becomes apparent that the 100-year War has begun again, with the Balarant moving into position to bombard the base. Among the falling ordnance, Mellowlink returns to the base for one last final showdown in the name of his fallen comrades.
