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.

Takumi soon discovers Natsuki’s secret that leads him to vent his anger in an egotistic battle against Kyoiichi at Akagi, thinking little of the huge disadvantage he has.

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.

The battle between the two Eight-Sixes have met Wataru’s satisfaction much higher than he expected, but he plans to decide the outcome of this battle with the judgement of the human body’s limitations. Takumi soon realizes he is losing grip of his pace. After the battle, a series of revelations take place among all the characters in preparation to what’s coming next.
