Storyline

Mathew Wayne, a resident of a small country town, was a mechanical genius whose aptitude and skills were passed down to his sons, Brian and Jason. After gaining leadership of his automobile factory from him, the brothers' skills became renowned throughout the country. Eventually, the Federation approached the brothers with an extremely profitable contract to help produce military vehicles for it. The Wayne brothers accepted the contract and created weapons without peer. A short time later, the skies turned dark with the Federation's encroaching airfleet, and towns and cities everywhere were ravaged by these armies—including Brian and Jason's home town. To their horror, the Federation was using the weapons and vehicles they themselves had designed to reshape the land to their pitiless will. Taking up planes whose designs had never been submitted to the Federation, the Wayne brothers prepare to destroy the Federation's mad scheme. They are aided by the four heroes from Mahou Daisakusen.
