This is simply the OVA summing up the major events and battles of "Initial D 4th Stage" much like the "Initial D Battle Stage" original summed up the first 3 seasons. Additionally, has 2 extra battles from the manga that were not incorporated into the original 4th Stage.

The Lancer EVO-driving group "Emperor" have defeated every racing team they've met in the Gunma region. Now they're out to challenge the duo of Mako and Sayuki and their SilEighty - the Impact Blue of Usui Mountain.

Initial D Final Stage takes place right after the end of Fifth Stage and shows the long-awaited final fierce downhill battle between Takumi's 86 and Shinji's 86.

Takumi Fujiwara is an aloof, spacey high-schooler who does delivery runs in his dad's Toyota AE86 in the dead of night. Despite working at a gas station and having friends who are car nuts, he doesn't know a single thing about cars. Takumi is introduced into the world of street racing and his natural talent draws attention from all across Gunma. Will Takumi face the challenges or back out from the call of the mountain passes?

Takumi Fujiwara finally joins Ryousuke and Keisuke Takahashi to create "Project D." Their goal is twofold: Ryousuke wants to develop his "High-Speed Street Racing Theory," while Keisuke and Takumi aim at improving their driving skills by facing powerful opponents on dangerous roads. The idea of Project D is to challenge street racing teams from other prefectures to improve both their uphill and downhill records. In order to attract the attention of the best racing teams, Ryousuke creates a dedicated website to announce the future battles of Project D and post the team's results. The fourth season of Initial D details the hardships and successes of the members of Project D as they try to become the best street racing team outside of Gunma Prefecture.

Following his victory over RedSuns leader Ryosuke Takahashi, AE86 driver Takumi Fujiwara is challenged by the Lancer EVO-based "Emperor," a group known for taking decals of racing teams they defeat, cutting them up and placing them on their cars like a fighter plane kill board. Takumi's undefeated streak is on the line as his AE86 is virtually no match against the more powerful and more agile four-wheel-drive EVOs of the Emperor team.

Shortly after graduating from high school, Takumi is approached by RedSuns leader Ryosuke Takahashi and offered to join him in forming a professional racing team. Before coming up with an answer to the proposal, Takumi seeks retribution by issuing a rematch to Emperor leader Kyouichi Sudou, who previously defeated him due to an engine failure. He is also challenged by Kai Kogashiwa, a second-generation street racer whose father was once a fierce rival of Takumi's father Bunta.

Initial D Battle Stage (special) will summarize all street races from the two TV series and movie and add one new race in the middle of it. 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" Tsuchiya Keiichi.

Iketani missed an opportunity to see Mako and hates himself for never calling to say he was sorry. By chance he runs into her 6 months later, and the situation is awkward. Iketani does not have time to talk at that moment, so they arrange a second meeting. Iketani goes to the meeting place early, but an old man who was left behind from a tourist bus asks Iketani to take him to his destination instead. Iketani being a nice guy, can't say no. Will he miss the meeting yet again?

Taking place in the sacred land of street running Kanagawa, once more Takumi Fujiwara will show his driving skills on his now legendary Hachi-roku.

Takumi Fujiwara is the son of the owner of a local tofu shop. At night, Fujiwara gets in his souped up AE86 Sprinter Trueno (AE86 Corolla GT(DOHC)) and races on the seldom-used Japanese mountain roads. One night, the Akagi Red Suns team, a racing club, challenges the Akina Speed Stars to a race on the mountain where Fujiwara lives. Keisuke, one of the leaders of the Red Suns, races his legendary Mazda RX-7 - only to be beaten by the mysterious Fujiwara.

Takumi Fujiwara and brothers Keisuke and Ryousuke Takahashi have formed "Project D", a racing team aimed at bringing their driving skills to their full potential outside their prefecture. Using the internet, Project D issues challenges to other racing teams and posts results of their races. Managed by Ryousuke, the team has Takumi engaging in downhill battles with his AE86, while Keisuke challenges opponents uphill. Among their rivals are the Seven-Star Leaf (SSR) and Todo-juku.Meanwhile, Takumi is caught off-guard on Mount Akina when he encounters his father Bunta and his newly acquired Subaru Impreza WRX Type R Version V.
