Candidate for Goddess (2000)

Thousands of years in the future, an intergalactic crisis has wiped out the planets across the galaxy. With their home planet gone, humanity turns to the remaining planet, Zion, as their last hope for survival.

But the mysterious alien species, Victim, has now reached the planet, and the only thing that stands between them and Zion's destruction are five "Ingrids" and their pilots.

Zero Enna has always dreamt of piloting an Ingrid, and is obviously delighted to be training at the Goddess Operator Academy (GOA). However, Zero isn't the only one, and he and his fellow pilot candidates and repairers will have to learn to work together if they are to rescue the human race from imminent extinction.
