Thanks to Naruko's sacrifice Sohoku manages to catch Hakone. Fukutomi admits he thought Sohoku would fall apart and yet they managed to catch up, but he says they can never prevail without a true ace. Imaizumi declares that he is the new ace and he will take first. Onoda is shocked and asks Makishima if it's ok. Makishima says it is fine because he and Toudou would never let the other finish in first as the ace. Imaizumi then decides to get reckless and move ahead on his own. Makishima keeps Toudou at bay and forces Fukutomi to pursue him. Everytime Fukutomi catches up Imaizumi puts on another burst of speed. We see how Imaizumi became addicted to road racing and how he first met the Kanzaki's. Finally we see Imaizumi thinking to himself and knowing he can win if nothing else changes. However a medical van is further back on the road. It picks up Naruko and has him withdraw from the race. They then clear the road because more racers are coming. Ishigaki collapses and then tells Midosuji to press on at full strength and he will win. An ominious wind then begins to blow as Midosuji begins to ascend the final 15km on his own.
