A colonial war that refuses to pick a side. The Zor aren't invaders, they're coming home to a planet humans claimed by accident, and both sides are right enough to make you sick about it. The mecha combat serves the moral collapse, not the other way around. By the end, there's no victory condition, only the weight of two civilizations realizing they can't both exist on the same world. This is what happens when you strip away the hero narrative and just let two desperate peoples collide.
The year is 2120, and humanity has rebuilt itself across the stars following Earth's catastrophic wars. On the colony world of Gloire, people have carved out a new existence, unaware that they're not the planet's first civilization. When The Zor return to reclaim what was stolen from them, the fragile peace shatters. These otherworldly beings aren't invaders in the traditional sense, they're remnants of a world that burned itself nearly to extinction before departing for survival. Now they've come home, and the human colonists stand in their way. As conflict escalates into all-out war, both sides are forced to pilot advanced mecha in brutal combat. Pilots on both fronts grapple with the moral weight of their battles. The fighting becomes increasingly desperate, grinding toward a confrontation neither side can truly win. Questions of rightful ownership, survival, and coexistence weigh heavy as the war spirals toward its breaking point. Super Dimensional Cavalry Southern Cross captures the chaos of war where there are no clear villains, only desperate civilizations clashing over one world.
