Synopsis by Cammila Collar
It is the year 2041 and an unknown enemy called Zeravire is moving through the galaxy, destroying each military base it crosses. One man, however, saw it coming long ago and has been preparing. The wealthy Klein Sandman is gearing his army up for battle and readying his greatest weapon: Gravion. This giant, powerful robot uses gravity itself as a source of energy. Piloting Gravion are two young men named Touga and Eiji. Eiji wandered onto Sandman's base in search of his missing sister, but fate had other plans for him.
