Synopsis

By the end of the 21st century, humanity discovered DG energy—divine grace energy—which transformed the economy and opened up space colonization. But when the first expedition reached Pluto, they ran into something unexpected: a massive, mysterious creature called Nergal that attacked without warning. To fight back, the military dug up ancient robot weapons from archaeological sites around the world, calling them the "G's Frame." Only girls with special abilities—dubbed "Ancient Girls"—could pilot these machines against the Nergal. The first unit took massive losses during the Jupiter Trojan campaign, and Unit 04's pilot, Minamiya Reiu, disappeared in the chaos. Years later, Reiu's younger sister Reika joins the AG Unit to find her and defend Earth from the Nergal threat. What follows is a story about friendship, piloting ancient mecha, and fighting for survival against an enemy that won't stop coming.
