Heavy Object

The world is now fragmented into four coalitions that constantly wage wars across their many borders. These wars are fought by a new class of weapons called Objects, which rendered all other forms of conventional warfare obsolete.

The base is attacked and Milinda's Baby Magnum is defeated by a more advanced and well equipped Object called the "Water Strider", forcing the rest of the military, led by Frolaytia Capistrano to retreat, while Milinda decides to stay behind and serve as a decoy. But Qwenthur refuses to abandon her and returns with Havia to aid her.

Reunited with Milinda, Qwenthur and Havia infiltrate the enemy base looking for a way to disable the Water Strider and allow Frolaytia's forces to launch a counterattack, but things go south when Milinda is captured and it's up to Qwenthur to challenge all odds to make sure his plan works. He manages to sabotage the Water Strider's self destruct mechanism, causing it to explode and allowing Frolaytia to capture the enemy base. Qwenthur and Havia are hailed as heroes, and then are immediately transferred to a new front, much to their dismay.

Because of the success of their escapades with the first Object, Qwenthur and Havia are transferred to the entrance of the Mediterranean to assist in combating another Object which has been drilling and selling oil to terrorists. After the Object attacks, they are able to infiltrate it and attach bombs to it, but they are unable to destroy it, until Milinda arrives in time for support.

With Milinda facing the hostile Object, Qwenthur and Havia's part in the battle seemed over, but the enemy Object begins systematically disabling Baby Magnum's weapons. Qwenthur uses a series of mines to damage the Object's rudders, causing it to break apart under the stress of its own high speed maneuvering.

Qwenthur and co. are sent to a joint operation in Oceania with another Object from the Information Alliance. Milinda quickly grows jealous of Qwenthur's fascination with the rival Object and its pilot. Quenser and Havia are then sent to scout a jungle for enemies, and stumble across Oceanian soldiers massacring a village.
