No ano de 1973, uma raça alienígena conhecida como BETA invadiu a Terra, durante 30 anos eles mataram bilhões de humanos e praticamente dominaram a maior parte do continente europeu e asiático. A humanidade desenvolveu armas humanóides conhecidas como TSF (Tactical Surface Fighters) para tentar vencê-los, mas isso apenas atrasava as forças inimigas. Em 2001, o império japonês encontra dificuldade no desenvolvimento dos novos TSF enquanto defende suas terras da invasão. A Nações Unidas enviaram uma proposta de um programa entre os EUA e o Japão para um desenvolvimento mútuo para um novo projeto de TSF, The Prominence Project. E o encontro entre duas pilotos, uma japonesa e outra americana, vão mudar os seus destinos drasticamente.
