Now for a complete waste of time.

The Planet Libertia was once known as the Planet of Death until the inhabitants installed giant mirrors to try and curb the extreme heat.
Alicia and her grandfather Professor Grace are developing the armour unit Legaciam said to be capable of surviving extreme heat but a group called the Guild led by a former friend wants the armour in order to investigate a mysterious tower, which is also what Professor Grace wants to do so together with Zeno they break out of the Guild's grasp and head to the tower which never gets resolved.
That was a waste of time, nothing gained from the effort put into the armour which Alicia is too petrified to even pilot, there appears to be some form of class war but it's barely touched upon, it's unclear what the ultimate goal is either, all we know is the tower makes a horrible sound that makes people die and that Legaciam was found there, nothing gets resolved.
No dub but wonderful musical score, wish you spent more effort on the story.
Final Verdict: Waste of time but the music is at least nice
