Itsuki Takeuchi

Itsuki Takeuchi (武内 樹 Takeuchi Itsuki, known as Iggy in the Tokyopop version) is Takumi's best friend; 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. He eventually purchases a turbocharger for his Eight-Five. Self-proclaimed "Lonely Driver".

Likes: Taiwanese bananas, cheesecake, all cars popular among street racers and horsepower, cute girls in miniskirts, his AE85, AE86 (both Trueno and Levin).

Dislikes: FF, his scooter, trash talkers, and Automatic diesel cars.

Special skills: Hill road takeoff.

Bloodtype: O

Takumi Fujiwara
He is his best friend in high school as well as his workmate. After discovering he is Akina's fastest, he envies his driving skills and bought an Eight-Five (in which he mistaken as an Eight-Six Levin). Itsuki gained inspiration after Takumi drove his car in an impromptu battle and would practice drifting to one day follow his footsteps.

Koichiro Iketani
He is his workmate at the gas station.

Kenji
Just like Iketani, he is a workmate at the gas station.

Saori
His first love interest whom Natsuki introduced him to. While driving her home, Shingo starts an impromptu battle with Itsuki (thinking it is Akina's Eight-Six) which resulted to a crash. Although Saori wasn't badly hurt, she dumps him due to bad memories.

Kazumi Akiyama
His second love interest. At first, she mistook Itsuki as a vandal when he was flirting with his 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 again.

Trivia

 * Itsuki returns to chapter 96 of MF Ghost where he still lives in Shibukawa and still works at the gas station (although it is an ENEOS EV station). He is married and has children. It is revealed that his body weight increased 20 pounds.
