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.

One day, he goes out on one of his usual missions, to retrieve illegal coils from two criminal brothers, Jony and Every Won. When he gets to their gang's hideout, however, there is another stranger there: a mysterious, cloaked captive that appears to be a young lady. Who is she and will this meeting change Kyoma's life?
