One man travels across country, smuggling illegal black diamonds to sell in order to pay for his father's pardon in South Africa.

Two mountain road racers, Nakazato and Takahashi, challenged each other to find the best racers, and defeat them in "battles". Nakazato was surprisingly defeated by an old Toyota Trueno AE86 (Corolla in the US) one night, and he searched for the person who defeated him, which lead him to the Speedstars, a local team. But the car who beat him was actually driven by a local Tofu shop owner's son, Takumi Fujiwara, who had unknowingly perfected the art of mountain racing through daily deliveries of tofu. Takumi was able to defeat Nakazato again, showing that he is no fluke. However, winning hasn't helped him home life, as his father, Bunta Fujiwara, was a drunkard (and a racing genius). His girlfriend Natsuki Mogi wants his attention even though she's got a dark and shameful secret, and his best friend Itsuki (who has no talent in driving) wants Takumi to teach him road racing...
