The first stage of Project D's Kanagawa expeditions is against Team 246: Satoshi Omiya and Kobayakawa. Although racing for their own pride, 246 are actually part of a grand plan initiated by Team Sidewinder's Go Hojo and Eiji Kubo. As the uphill race begins, Kobayakawa is about to be shown the true ability of Keisuke Takahashi.

As the first battle winds down, the downhill between Takumi’s Eight-Six and Omiya’s NB8C Roadster begins. As both cars reach their limits, the control of the drivers will determine the outcome. Against Omiya’s miraculous car control, will Takumi be able to win? Another factor will come into play.

Kanagawa's Second Line will be against RT Katagiri, where Takumi encounters Kai Kogashiwa: a former rival from Irohazaka; graduated from street racing and now a professional racer with his MR-S. However, Takumi is starting to show a "Zone" that had evolved from the Purple Shadow races, a zone that even Ryosuke cannot explain. The winner of this race is up in the air.

As the out-of-control FC and R32 hurtles down the mountain, only a miracle can stop these two missiles from spectacularly crashing! Meanwhile, Project D prepares for their last battle of Kanagawa against the secretive Team Sidewinder. That is, until the SpeedStars find out that Takumi’s opponent will be an Eight-Six.

The final battles for Project D are here, and it all starts with the uphill battle between Keisuke's FD and Go Hojo's NSX. But as Rin understands, there is a fundamental difference between his younger brother and Keisuke, one that might determine this race.

The battle between Keisuke and Go Hojo continues. Keisuke's good run behind Go Hojo led to many feeling unbelievable, including Go Hojo himself. Then entering the second round, the match gets more intense. Who will take this uphill climb battle?

Takumi and Shinji continue with their match with Takumi, still bewildered by Shinji, starts to focus. But suddenly, Shinji allows Takumi to pass, which disturbs Takumi even more. Even Kubo is utterly disheartened by the turn of events, but both Go and Ryosuke believe this was inevitable, creating a suitable conclusion to Project D's expeditions.
