In the future, Nikola Tesla's dream of a 'World System' of electricity is realized. Cords and batteries are a thing of the past, and now people can directly draw energy using devices known as 'coils.' Some people, however, modify these coils for destructive purposes. Mabuchi Kyoma, a man who lives in ruins and has a passion for 'vintage' gas-powered cars, has good reason to know what damage these coils can do. He takes on assignments from a large woman known as Marie, recovering illegal coils in exchange for cash and gasoline.
