A New nightmarish opponent arrives on Mt. Akina challenging Takumi in a downhill battle. Also, Itsuki gets a new upgrade for his Eight-Five as it is demonstrated on the downhill.

Initial D Battle Stage 2 summarizes the major street races from the recent Fourth Stage TV series. While the first Battle Stage had every battle re-animated from scratch, the only episodes altered in the second version were the early races in stage 4, to match with the visual style of the latter portion of Stage 4. Additionally, two races that were previously seen only in the manga were animated specially for the feature. The first race is Takahashi Keisuke vs. Smiley Sakai, and the other is Keisuke vs. Kawai Atsuro. Both races are noticeably shorter than the other races in the feature.
