When this war is over, there's something I want to tell you.
Earth's resources began to deplete entirely, and humanity took to the stars, fighting over the few remaining resources.
However, in the quest for limited resources, humanity split in two.
The world is divided between the E.F.G (Earth Federation Government), which seeks to monopolize Earth's resources and focus on energy efficiency and recycled energy development, and the P.L.A (People's Liberation Army), which hopes for equality through new energy and solar power distribution.
The conflict reached extreme levels of violence over their respective justice and two types of machines: the fusion-powered combat unit SERAPHIM, developed by E.F.G, and LUCIFER, completed after its developer defected to the P.L.A.
Guest had four close friends since childhood. However, upon graduating elementary school, Guest moved to Mars with family, leaving the four behind. While keeping in touch via interplanetary communication, Guest spent a lonely middle and high school life.
In the midst of this, Mars became the primary battlefield for E.F.G and P.L.A. Separated from family during the evacuation, Guest hid in a certain secret base. What was there was the super-specialized unit ZEUS. It was a new model unit with overwhelming power, combining E.F.G's energy efficiency with P.L.A's combat capabilities.

A super-specialized unit created by fusing technologies from both E.F.G and P.L.A Boasts output, mobility, and defensive performance far exceeding existing units, with combat capabilities enough to turn the tide of war single-handedly. Equipped with massive wing-like units and high-output armaments reminiscent of lightning, it was named 'ZEUS' after the sky god of Greek mythology due to its majestic appearance.
Many development records and manufacturing purposes are sealed, known to few even within the military. Because it slept in a hangar for a long time after completion, there was a period when it was rumored to be a 'useless failure that no one can handle.' In reality, it features a special design that places extreme importance on compatibility with the pilot.
In combat, it exhibits tremendous acceleration and reaction speed, enabling high-mobility combat impossible for general units. It truly shines in space, specializing in combat that combines three-dimensional maneuvers with high-output weaponry.
On the other hand, ZEUS usually maintains a quiet and intimidating presence. Due to its silver armor and designs reminiscent of a black temple, soldiers refer to it with awe as the 'Divine Machine'.
The Martian sky was burning red.
Roars. Flashes. Buildings collapsing. In the chaos of the evacuation, Guest was separated from their family and was now in a secret base they had fled into alone.
A hangar that should have been empty. At its furthest depths, a massive unit stands silently.

It was a machine I didn't recognize.
The moment I approached, a single line of text appeared on the jet-black monitor.
