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.

What would happen if the Eight-Six gets a new upgrade? That’s exactly what Iketani and Itsuki has been thinking about to increase the performance of Takumi’s vehicle. But would Bunta allow it? Elsewhere, team Emperor’s winning streak isn’t slowing down as they continue to sweep across Gunma, defeating every race team with ease. Their next target, Akina’s Eight-Six.

Kyoiichi senses an uncanny fighting spirit within the Eight-Six’s driver, as he gives Seiji strict rules against the race. Seiji however decides to ignore these rules and launches his Evo IV into full power. Takumi is outclassed in almost every category as the Evo IV’s power is truly amazing. The battle risk escalates when the race reaches it’s second half point of the coarse.

In his heart, Takumi couldn’t accept his victory over the Evo IV and decides to make a vow. To add to his already uneasy thoughts … anonymous messages are being sent to Takumi concerning his relationship with Natsuki.

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.

Kyoiichi is realizing just how incredible Akina’s downhill is, yet he has full confidence in his rally tuned Evo III. Takumi soon realizes the difference between the Eight-Six and the loud banging horsepower of the Evo III. It seems that Bunta instinctively knows of the race taking place as a major turning point is about to happen in the series.

With the Eight-Six out of the picture, the RedSuns has become the main representatives of Gunma, as every local racer within the prefecture are in favor of Emperor’s defeat. Ryosuke has returned on the street to defeat the revenge-seeking Kyoiichi, who plans to use his theories of motorsports against the White Comet. Also, Iketani and Kenji spot another racer from a neighbouring prefecture.

Mt. Akagi’s battle continues, as Ryosuke has his own theories about streetracing…and he plans to demonstrate it’s difference on Kyoiichi’s Evo III. Back in Akina, Takumi’s routine way of life is gone with the absence of the Eight-Six and the discovery of Natsuki’s secret.

Initial D Battle Stage (special) will summarize the major street races from the two TV series. Rather than simply using clips from the TV series, the new special will entirely re-animate all of the original CG car and background footage with new state-of-the-art computer graphics rendering. The special will also feature entirely new Super Eurobeat music and guest commentary from legendary "drift racer" Keiichi Tsuchiya.

The Toudou School brings in a professional driver to face Project D in a rematch. With reputations on the line, Ryosuke must decide who will represent the team.

The Toudou School's driver knows all about exploiting a challenger's blind spot. If Takumi hopes to win, he'll have to find a way to leave his opponent in the dark.

Takumi and Shinji continue with their match with Takumi, still bewildered by Shinji, starts to focus. But suddenly, Shinji allows Takumi to pass, which disturbs Takumi even more. Even Kubo is utterly disheartened by the turn of events, but both Go and Ryosuke believe this was inevitable, creating a suitable conclusion to Project D's expeditions.
