Hurricane Keiko has arrived! The newscast weather segment. Usually the last thing anyone ever thinks about (unless they said "sun" and it wound up being "rain") but Keiko Nakadai's going to change all that. Toiling in obscurity for years at a horribly rated TV station, Keiko has figured out what the weather report needs and doesn't mind taking off her top (or lifting her skirt) on the air to do it. The ratings aren't going to go down, that's for sure. 
Of course, some of the people at the station don't find this appealing, and decide that Keiko's got to go. They devise a series of horrible "accidents" for her, but Keiko usually seems to be about a step ahead of them. 
Eventually, everyone at the station will discover that there's far more to her than meets the eye as Keiko's star rises incredibly quickly ... and as her importance increases, Michiko Kawai's (the old weather girl) drops. Something has got to be done, but who can do it?

There are many street races in the Initial D Series. This OAV has no plot other than to collect all the street races into one stage. The dialog during the original races is left in.

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.

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.
