Itsuki Takeuchi

Itsuki Takeuchi (武内 樹 Takeuchi Itsuki, known as Iggy in the Tokyopop version) is Takumi's best friend and a member of the Akina SpeedStars.

He provides the comic relief in the series, and is generally quite loud and obnoxious. Itsuki works part-time at a gas station with Takumi and Iketani; Itsuki plans to use the money he earns to buy an AE86 Corolla Levin (to complement Takumi's AE86 Trueno) but mistakenly buys an inferior (less power, poor brakes, less chassis bracing, and looser suspension) AE85. This upsets him until Takumi takes him for a drive (ultimately racing it downhill), demonstrating that the driver's skill can make a difference. With a car, he is a self-proclaimed member of the Akina SpeedStars. Unlike Kenji and Iketani, Itsuki is the most optimistic and excitable "member" of the SpeedStars. He eventually purchases a turbocharger for his Eight-Five. Self-proclaimed "Lonely Driver".

His first (second in the anime) love interest. At first, she mistook Itsuki as a vandal when he was flirting with her older brother's Eight-Six Levin. The following day, she took a liking after covering her the coin shortage in the taiyaki stand. She also taught Itsuki how to drift and found it easier to learn from her whereas he finds learning from Takumi difficult. As she parts to Saitama with her brother, Itsuki became heartbroken. He eventually saw her again during Project D's battle against Sakamoto. Kazumi eventually dumped him, leaving Itsuki disheartened.
