A lone woman pilots a ship across dead planets, hunting the one empire that took everything from her. Emeraldas moves with the swagger of someone who stopped asking permission years ago. The four episodes don't have time for bloat, they hit hard, move faster, and leave you wanting the story to keep going instead of overstaying what it actually is.

In the far future, a race that sees itself as destined to rule, the Afressians, is trying to take control of the galaxy. Standing against them is Emeraldas, a mysterious woman who roams space alone aboard her ship, striking at their forces with an arsenal of advanced weaponry. For humanity she is the last real hope, and she is haunted by the memory of a love she lost. When the scheming Commander Eldomain abducts a group of civilians, Emeraldas is lured into a lethal trap that may be too much even for her. This four-episode OVA is a science fiction action adventure built around a solitary warrior and her battle with an oppressive power.
