The battle between Keisuke Takahashi and Wataru Akiyama is the thirty-sixth battle of Initial D.
Prior to the Battle[]
After the Impromptu battle in Second Stage, Wataru said to Keisuke that he will challenge him again later on. Wataru finally got his chance to battle Keisuke again, properly this time while Project D was on their expedition in Saitama.
During the Battle[]
It's pouring with rain at Maze, but that does not discourage either driver - in fact, it emboldens Wataru, who has replaced his Levin's turbo engine with a supercharged 4A-GZE, allowing for smoother power delivery compared to Keisuke's powerful but finnicky turbo 13B. The result of the first hillclimb is inconclusive, and the battle drags on for a while until both drivers are exhausted.

Wataru spins out and Keisuke dodges away
Already fatigued, Wataru tries to increase the speed of his wipers and forgets a drain is nearby, losing control of the Levin as he runs over it and narrowly being avoided by Keisuke.
After the Battle[]
Defeated officially this time, Wataru concedes to Keisuke.
