Following "Second Stage" in 2000, "Initial D: Extra Stage" was aired as a spinoff to the original series. This story focused on the all-female Impact Blue team of Usui Pass and their point of view of the recent events of "Second Stage" and the upcoming "Third Stage" movie. This was followed by "Extra Stage 2" in 2008, which look at the relationship between Impact Blue's Mako Sato and Iketani of the SpeedStars (following on from the original side-story in the manga).
