Atsuro Kawai is the hillclimb racer and the leader of the Tochigi-based "Seven Star Leaf". He seems to be a decent enough driver, again favouring the grip racing techniques, but his mastery of it is uncomparable to that of Takeshi Nakazato. His car is powered up to 400 hp.  Atsuro races against Keisuke during Project D's first expedition in Tochigi.

Takumi Fujiwara and brothers Keisuke and Ryousuke Takahashi have formed "Project D," a racing team aimed at bringing their driving skills to their full potential outside their prefecture. Using the internet, Project D issues challenges to other racing teams and posts results of their races. Managed by Ryousuke, the team has Takumi engaging in downhill battles with his AE86, while Keisuke challenges opponents uphill. Among their rivals are the Seven-Star Leaf (SSR) and Todo-juku.

Only the fearless survive in the white-hot world of street racing, as teams take on dangerous roads in the shadow of Mt. Akina. Behind the wheel of the mysterious "Ghost of Akina" is Takumi, on his way to becoming the greatest racer ever. (Source: Tokyopop)
