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.
