Nobody's heard of this one. A 1987 OVA where the whole thing is just treasure hunters racing against time in a world that's already dead, chasing an energy source that could bring it back to life. The Demsters aren't some philosophical threat, they're just there to take it from you, and you have to move faster. It's lean and purposeful, built for an audience that doesn't need five episodes of setup to care about the hunt. The mecha is functional, not pretty. Everything exists to serve the chase.
After civilization collapses, the wasteland becomes home to treasure hunters and worse things. Riot leads a small crew across this broken landscape, chasing rumors of the Rido: a legendary power source from the vanished Quall civilization that supposedly grants life itself. The only map to it lies in the Eyes of Zalem, ancient artifacts scattered across hostile terrain. But Riot isn't alone in this hunt. The Demsters, a ruthless faction hungry for ultimate power, pursue the same prize with brutal efficiency. What starts as a race through ruins and abandoned cities spirals into direct conflict between those who'd use the Rido to rebuild and those who'd weaponize it for dominance. Mecha clashes punctuate desperate survival moments as Riot's ragtag team pushes deeper into dangerous territory. The question driving everything forward: who deserves control over infinite power? The crew that stumbles onto it, or those organized enough to take it by force? In a world where resources are scarce and hope rarer still, that answer determines everything.
