Peace is a trap in this universe, and the moment you believe the war is finished, it starts again. The Yuman don't negotiate or compromise, they reset. You get two episodes to watch civilization realize it never actually won, just postponed losing. This is 1991 sci-fi OVA violence: economical, consequential, no time for you to catch your breath between the false security and the ambush.

In 2291, people live quietly inside an enclosed mega-city after a recent, devastating war between humans and the genetically enhanced Yuman. That calm will not last. The Yuman leader refuses to treat the conflict as finished and moves to restart it, backed by GORN, the controlling artificial intelligence of the machine force MME, which was thought destroyed along with the MME Citadel two centuries earlier. The two-episode OVA is mecha science fiction built on action and adventure.
