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.
