On Mars, revolution simmers beneath colonial occupation. Two elite BAHRAM pilots, Radium and Viola, are selected for a classified mission that will change everything: testing Orbital Frames, revolutionary mechas powered by the mysterious metatron ore. Their superiors promise these machines will finally break Mars free from UNSF control, but the cost of liberation may be higher than either pilot imagines. What begins as military duty becomes something far more complicated when personal stakes and moral questions blur the line between soldier and saboteur. The tension between duty to Mars and doubt about their mission's true purpose creates a slow-burning conflict that reaches toward catastrophe. Romance and camaraderie fracture under the weight of impossible choices. This OVA captures the human side of war, focusing on how ordinary soldiers become entangled in extraordinary circumstances. The Deimos Incident looms as an inevitability shaped by ambition, desperation, and the people caught between them. Expect action sequences grounded in genuine emotional stakes and a story that asks whether fighting for freedom justifies any means.
