Ku-AG 101 (unyaka we-101 wekhalenda lesizukulwane esithuthukisiwe) ibhizinisi eliyimfihlakalo elaziwa kuphela ngokuthi “i-UE”, noma “isitha esingaziwa”, lihlasela futhi licekele phansi ikoloni lasemkhathini i-Angel. Lokhu kuhlasela okunonya kuba nedumela elibi njengokuthi “Usuku INgelosi Ewa Ngayo”, futhi kuphawula ukuqala kwempi yesintu yokusinda. Uchungechunge luqala ngo-AG 108 lapho i-UE ihlasela ikoloni lasemkhathini i-Ovan, lapho manje uFlit Asuno ehlala khona ngemva kokuphunyuka ekoloni i-Angel ngaphambi kokubhujiswa kwayo. Umama kaFlit ngaphambi nje kokuba abulawe yi-UE, unikeza indodana yakhe into ebizwa ngokuthi “AGE Device”. Ngaphakathi kwayo uthola ipulani yesikhali esinamandla sasendulo—umesiya wasendulo okuthiwa “uGundam”.
Kusukela kule miklamo, u-Flit uchitha iminyaka embalwa ezayo efundela ubunjiniyela esikhungweni se-Earth Federation ku-Nora space colony futhi aklame i-Gundam AGE-1. Eminyakeni eyisikhombisa kamuva, ngo-AG 115, uFlit uqeda iGundam AGE-1 Normal, njengoba nje i-UE ihlasela uNora, futhi iyisebenzisele ukusiza ithimba lempi yempi yeFederation "Diva" ekukhipheni izakhamizi zekoloni ngaphambi kokuba libhujiswe. Ezimisele ngokuletha impi ku-UE ngokucekela phansi ikhaya lakhe kabili, uFlit uyavuma ukusebenza eqenjini likaDiva lamasudi eselula elishayela iGundam. Ngemva kokuthola idatha eyanele namandla ezempi ukusungula inkambo yesenzo, ithimba le-Diva kanye nabalingani babo baqala ukuhlasela okuphumelelayo okwabhubhisa inqaba eyimfihlo ye-UE ku-Ambat asteroid. Lapho zifunda ukuthi i-UE empeleni iyinzalo yomuntu okuthiwa yehlulekile eyathunyelwa ukuyokwenza iMars ikoloni, ishiywe i-Earth Federation, eyakha isizwe sayo kule planethi ebomvu ebizwa ngokuthi iVeigan.
