Deunan carries the weight of every decision that keeps Olympus standing, knowing that protecting the city might mean betraying everything she joined up to defend. The Argonauts aren't mindless terrorists, they're asking the questions that actually matter, and the show doesn't pretend they're wrong just because they're dangerous. Watching her hunt someone she believed in, watching her realize the city she's saving might not deserve saving, turns this from a military action series into something that guts you.

Olympus stands as humanity's last refuge after a devastating war left the world in ruins. The city now serves as the center of command for what remains of society, but a terrorist group called the Argonauts threatens it. Deunan, a former LAPD SWAT officer, leads a special military force made up of cloned humans and her cyborg partner Brialeos to keep the city safe. Her task becomes harder when Al Ceides, the Argonaut leader thought to be dead, resurfaces and starts causing trouble. The OVA mixes action and mecha combat in a science fiction setting.
