Over the course of the Hundred Years War, many men rose to power and took leadership roles in the Secret Society. One such man was Gilgamesh General Albert Killy, whose expertise in manipulating lives and military resources placed him in an ideal position to capitalize on his agenda of greed and deception. At the end of the war, Killy and his men launch &quot;Operation Lido,&quot; the invasion of a Melkian research base hidden inside an asteroid on the galactic rim. There, they steal not only a strategic reserve of gold ingots, but also the top secret prototype of the Melkian Perfect Soldier Project. From that point on, they become the direct target of a Melkian investigation, but Killy has already taken many steps to make himself a force to be reckoned with. Ironically, the one element Killy does not foresee in this deadly game proves to be the most dangerous: Chirico Cuvie.

A century of bloodshed between warring star systems has plunged nearly 200 worlds into the flames of war. Now, an uneasy truce has settled across the Astragius Galaxy... 
Chirico Cuvie, a special forces powered-armor pilot is suddenly transferred into a unit engaged in a secret and highly illegal mission to steal military secrets - from their own military! Now he's on the run...from his own army! 
Unsure of his loyalties and to cover their own tracks, Chirico is left behind to die in space. Surviving by luck, the renegade is now hunted by both the conspirators and military intelligence. 
He is driven by the haunting image of a mysterious and beautiful woman - the objective of their mission, and his sole clue to unraveling their treacherous scheme. But the conspirators will do anything to preserve their mysterious agenda...

Released in 1985, this OVA tells a critical part of the story between the TV show's Uoodo and Kummen arcs. Although the TV series covered the Red Shoulders in some detail, we didn't get to see much of Chirico's time there or the people involved, and we get both of those here.
