The Madox 01 Slave Trooper battlesuit is the fastest, most agile and most dangerous weapons system ever created for ground warfare and now it's in the hands of a clumsy High School student who's lost the manual and is late for a date with the girl of his dreams. When Koji Sugimoto found the missing Madox he never thought he'd end up a wanted man! But now he's locked into the U.S. Army's toughest war machine on a head-long charge through the streets of Tokyo. Out to destroy him is the maniac Lieutenant Kilgore and his minitank who was beaten once before in test runs against the Madox, Kilgore is obsessed with trashing the battlesuit and reducing its hapless pilot Koji to a greasy spot. Meanwhile Elly Kusumoto, the Madox designer just wants to rescue her precious mecha before its too late... Koji has a date tonight in Shinjuku with his long-lost love Shiori, but with Kilgore, Elly, the cops, the marines, the defense forces, the tanks and the helicopter gun ships out to get him, he's in for the ride of his life, should he live that long!
