During the first test of the revolutionary personal battle suit, the MADOX‑01, ace female pilot Elle Kusomoto obliterates an attacking tank force and humiliates Lt. Kilgore, Japan’s most macho tank jockey. Kilgore swears revenge, and he gets his chance when the prototype MADOX literally falls off the back of a truck in the middle of Tokyo. The suit, which has already slipped off one truck, crashed through a bridge, and landed in the rear of another, ultimately ends up in the hands of college student Koji Sujimoto. Intrigued, Koji foolishly experiments with the MADOX without reading the manual, only to find himself trapped inside and rapidly zooming through downtown Tokyo.
