A single OVA that builds a world hotter than the sun itself, then leaves you standing at the edge of it. The mecha designs breathe weight and purpose, these aren't toys, they're survival gear for a planet that wants you dead. The setup is sharp enough to demand a sequel that never came, which is either the cruelest thing about it or the most honest: sometimes a story shows you everything it needs to in thirty minutes and stops. This hits hardest for viewers who prefer their sci-fi grounded in heat and desperation over cosmic melodrama.
On the planet Libertia, once feared as a world of death, humanity has built three enormous mirrors and made what looks like an ideal place to live. Professor Grace and his granddaughter Alcia live there in peace until Guild soldiers raid their home, searching for the professor and for Legaciam, a special Armor that can endure extreme heat and reach places where people could not survive. Alcia is piloting the suit to help her grandfather with testing when the attack comes, and she only just gets away. The Guild will stop at nothing to seize Legaciam, leaving Alcia and her friends on the run. The single episode is a mecha action story in a science fiction setting, built around a chase and the question of why the Armor matters so much.
