Sky Girls OVA

Synopsis

After Earth's first battle with the alien Worms, the planet suffered immense damage—vast regions flooded and countless casualties. When the Worms reappear, nearly every capable fighter is conscripted into the resistance. Otoha Sakurano, Eika Ichijou, and Karen Sonomiya are chosen for a specialized "Sonic Divers" unit, young women equipped with high-tech exoskeletons to enhance their combat abilities. When their stealth carrier is unexpectedly and fiercely assaulted, the three must don their suits and demonstrate that their team is prepared to defend humanity.
