An ambitious racer who started when he was very young, Akio is in his final year of high school as the story begins. Drove his friend's red Nissan 300ZX (Z31) until, after a humiliating loss to Tatsuya Shima, he discovered &quot;the Devil Z&quot;, a Nissan Fairlady Z S30Z (known as the Datsun 240Z in certain markets) which is supernaturally fast and extremely hard to drive. Regarded as a legend on the Wangan, though he is actually a humble young man. Still, despite his gentle demeanor, he's dead serious about racing. In fact, he is so serious that he skips school (to the point of repeating a grade) to drive the Devil's Z. Like virtually everyone else in the manga, he has trouble forming intimate relationships, although he has made some slight inroads with Reina Akikawa. His day job is a waiter for a fancy restaurant, but then got fired for showing up late too often due to late night racing. He's regularly exposed to the active social scene at the heart of Tokyo. He was already a pretty accomplished racer with his old car, but behind the Devil Z, he's nearly invincible. He also has tremendous adaptive ability and can learn to drive virtually anything.

Based on a seinen manga by Kusunoki Michiharu serialised in Young Magazine. 
The story gets its roots from the actual street racing that occurs on Tokyo's Shuto Expressway, one stretch of which is known as the "Wangan", literally meaning "bay side" (although it is generally used to refer to the freeway), the longest, straightest road in the entire country. Of course, there's also lots of traffic to contend with, including a fair number of heavy trucks. Because of this, the action is inherently hazardous, and wrecks are common. Blown engines are also a frequent hazard, especially with the extreme-high power engines. 
One day, Akio Asakura, a third year high school student, is driving his Fairlady Z (Z31) and is challenged by Tatsuya Shima, a doctor, in his black Porsche 964 Turbo (nicknamed the "BlackBird"). With a friend in the passenger seat and two girls in the back, Akio pitifully tries to win, but is defeated. Determined to become faster, he goes to the junkyard to buy parts for his car, when he sees a pristine, unscratched midnight blue Fairlady Z (S30) in the junkyard. Intrigued as to why such a machine is about to be junked, he buys it. He soon finds that the car is unnaturally fast due to a tuned L28 engine, bored and stroked to 3.1 liters combined with twin turbos, which produces 620bhp. He also finds that all of the car's previous owners had unfortunate accidents in it, starting with the first owner's death. The manga follows Akio's various encounters, though the central plot revolves around his constant battle with the BlackBird for superiority.

When high school student Akio Asakura loses a high speed race to a Porsche 911 Turbo known as "Blackbird," he goes to a junkyard to find parts for his car - only to discover a blue first-generation Datsun Fairlady Z (S30), which he buys. Akio later discovers that not only is the Z tuned to 620 bhp, it's had a dark history of unfortunate accidents with its previous owners. Making matters more complicated is the fact that the last owner shared the same name with Akio. With the "Devil Z," Akio forms a new rivalry with the Blackbird and its driver Tatsuya Shima.
