Hundreds of years ago, a planet inhabited by humans suffered a violent meteorite impact. And human civilization was almost destroyed by the meteorite shock wave. The impact of meteorites not only permanently changed the shape of the planet's continental plates, but also disrupted the planet's magnetic field at high altitudes. All modern aircraft will fail at high altitudes, and humans will lose the sky.
Now hundreds of years later. People rebuilt countries and civilizations on the ruins. However, with the revival of mankind, wars that determined the world situation inevitably came.
Doug, a former mercenary, embarks on a journey of self-discovery after a war. This is how the adventure story of the girl and the mecha unfolds.
