The relentless march of science and technology, the mastery of biotechnology... all of this should have been our salvation, freeing us from the chains of conflict and suffering, leading us towards an era of endless prosperity. Eternal Calendar, year 2030. Earth, once the cradle of humanity, is now beyond human control. Only 258 survivors remain, and a single Gundam.
