Sven flies for the "right" side until the moment he realizes there is no right side. Three episodes is enough time to dismantle everything Gundam Seed told you about Natural versus Coordinator, enough to show a soldier realizing his war is someone else's science project. The Stargazer itself is the proof: a machine designed for exploration, weaponized by people who needed a weapon more than they needed discovery.

In C.E. 73, the ongoing friction between Naturals and Coordinators erupts into another war between the Earth Alliance and PLANT, set right after the Break the World event. Sven Cal Bayan, a 19-year-old Natural, flies the Strike Noir for Phantom Pain, an elite Earth Alliance squad, and reliably completes its anti-Coordinator operations. Selene McGriff, a 28-year-old Coordinator, is a researcher at the neutral DSSD, where she helps build the Stargazer, a mobile suit meant for exploring space. The two come from entirely different worlds, but the spreading war pulls their paths together. The story plays out as a three-episode mecha science fiction net release.
