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 it appears that the FD vs. Supra battle is giving no quarter, the question is, is it possible for Keisuke to hold off Minagawa's professional pressure? Meanwhile a new racer appears on the slopes of Hakone, and its evident he wants to kill himself, and take anybody with him!

Keisuke's next opponent in Kanagawa's Four Lines of Defense is the leader of Team Spiral, Ryuji "Zero" Ikeda. Ikeda believes in his "Zero Theory", where the driver thinks of nothing except being one with the car to create the ultimate racer. Quite similar to Ryosuke's Fastest Racer Theory, Ryosuke also notices a few flaws in Ikeda's theory. A flaw that would arise as the wet conditions create a fog battle.

The downhill battle between Takumi and Hiroya "Zero 1" Okuyama's S15 starts, with Okuyama waiting to attack until the later section because of the fog. However, he hasn't considered the ability of Takumi's adaptibility skills. Whilst this is on, another battle is in the midst: Ryosuke's inevitable battle with the driver known as 'Shinigami', Rin Hojo.

The destined battle between Ryosuke and Rin 'Shinigami' Hojo has begun, over a girl named Kaori. As the race progresses on, the story of Ryosuke, Hojo and Kaori is revealed. And as Ikeda of Spiral Zero spectates the race from behind, it's obvious that this race of fate has quickly risen well beyond dangerous.

As the battle get more dangerous, several confessions come into play that create the full picture behind the feud between Ryosuke and Rin, and how Rin's actions played a huge part in Kaori's suicide. But as they approach the end of the track, Rin's tires and brakes are completely shot, turning his R32 into an unstoppable weapon.

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?

The intense hill climb battle between Keisuke and Go Hojo is coming to the end of second round. Keisuke engages in attack mode and Go Hojo starts to get tense. Meanwhile, Shinji Inui has revealed to especially Mako and Sayuki, who has been with him, that he would be the racer of the downhill battle against Takumi.
