Emperor, a team of Lan Evos from the Tochigi prefecture has arrived with the goal to crush every team in Gunma. Soon they realize the fastest car in Gunma isn’t just Akagi’s White Comet, but also a new downhill legend known as Akina’s Eight-Six.

The Eight-Six has returned undergoing a major change. Takumi soon test-drives the new performance much to his mixed satisfactions and disappointments, but what he doesn’t understand is what Bunta knows what’s within that car. Also, the relationship between Takumi and Natsuki is falling apart, but Itsuki’s heart is shaken with the appearance of Kazumi.

After Wataru issues a short-lived battle against Keisuke, his sister Kazumi introduces him to Itsuki leading to a chance meeting with another Eight-Six driver. At first everything seems right with the meeting, but because of Takumi’s naïve reaction to his car’s new downhill weapon, Wataru rubs it the wrong way as his bad side emerges.
