Early one morning on Mt. Akina, Koichiro Iketani witnesses an impromptu battle between Keisuke Takahashi of the Akagi RedSuns and a mysterious Toyota Sprinter AE86 (nicknamed "Eight-Six"), which outmaneuvers Keisuke.
Several days later, Iketani invites his gas station workmates Takumi Fujiwara and Itsuki Takeuchi to a meet with his street racing team, the Speedstars, on Mt. Akina, but are surprised to see the whole Akagi Red Suns already there. Keisuke wanted to find and race the "ghost" Eight-Six whereas Ryosuke, Keisuke's brother and leader of the Red Suns, uses the meet to initiate his plans to dominate the Kanto region. The Speedstars are humiliated by the speed of the RedSuns, but this doesn't stop Iketani from trying to keep up. As he starts another run downhill, he crashes into the guardrail after running over a sharp bump.
