After losing a street race to Tatsuya Shima's legendary "Blackbird" Porsche 911 Turbo, high school student Akio Asakura purchases a heavily-modified first-generation Datsun S30 Fairlady Z from a junkyard. The car has a dark history of accidents, leading some to believe it's cursed; hence its nickname "Devil Z." Akio also discovers that the Z's first owner shared his first and last name, and was killed in the car during a race with the Blackbird. Meanwhile, fashion model Reina Akikawa joins the rivalry between Akio and Tatsuya with her modified Nissan Skyline GT-R R32.
