Rikako Ota is the daughter of RGO owner Kazuo Ota, and an aspiring tuner herself. Known to inherit RGO from her father after his retirement, she follows her father's footsteps as a tuner by engaging in tuning herself. When Eiji Kamiya comes over to Tokyo and works for RGO, she tunes his Evo along with him and even comes along during his battle with the Devil Z and Blackbird. Her first solo tuning work was with the Devil Z, after Akio specifically asked for her help in tuning the Z's engine. Her addition of a dry sump lubrication system on the Z's L28 engine resulted in Akio's victory against Kijima's FC and the Blackbird. Since then, Jun Kitami has entrusted her with tuning the Devil Z, as he told her before the race with the Z's race with Kijima and Blackbird that he would no longer tune the Devil Z, infact she had a boyfriend. For unknown reasons, the shop was renamed Rikako Speed Factory when Rikako possesses ownership of the shop.

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.
