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, humanity has rebuilt itself from the ashes of a brutal interstellar conflict. The Yuman, once mortal enemies, have accepted an uneasy peace, and for the first time in generations, people taste something close to normalcy. But fragile peace crumbles when the Yuman leadership decides the war never truly ended. They're simply regrouping, rearming, and preparing to finish what they started. As hostile forces mobilize across the galaxy, the burden of defense falls on soldiers who never wanted to fight again. Caught between duty and the weight of old trauma, they must confront whether peace was ever possible or just a temporary illusion. Explosions light up the darkness as mechas clash and space stations burn. This two-part OVA strips away sentiment and presents war as a brutal cycle. Action sequences drive forward with relentless momentum while characters grapple with the cost of survival. The result is lean, intense sci-fi that refuses easy answers about conflict and coexistence.
