A woman in a power suit turns a tank commander's ego into scrap metal, then watches him chase her prototype through Tokyo traffic in his own mecha like a jilted ex with a grudge. The suit itself becomes a character, getting stolen, dropped, and passed between vehicles like the world's most dangerous game of hot potato. This is pure '80s testosterone collision: genuine humiliation followed by exactly the kind of petty revenge that escalates into absolute chaos.

During the first test of the MADOX-01, a new personal battle suit, test pilot Elle Kusomoto wrecks an attacking tank force and embarrasses Lt. Kilgore, a proud tank officer who vows payback. His opening comes when the prototype tumbles off a truck in the middle of Tokyo. After falling off a bridge and landing in another truck, the suit ends up with college student Koji Sujimoto. Curious, Koji starts tinkering with it without reading the manual first. Bad move. Before long he is sealed inside the armor and racing through downtown Tokyo. The result is a one-episode 1987 OVA of action and mecha science fiction.
