Kenji

Kenji (健二) is a member of the Akina SpeedStars and Koichiro Iketani's childhood best friend.

He is the second-best driver in the SpeedStars and was set to race Keisuke Takahashi in Iketani's stead, though he was replaced when the Eight-Six arrived at the last minute. His last name has never been revealed.

The White Ghost of Akina
Kenji is first seen in Act 1, accompanying Takumi, Itsuki and Iketani at times. He generally provides tactical information and necessary background, but not much else.

MF Ghost
Kenji shows up to the gas station to share information about MFG with his fellow ex-SpeedStars. He is married with kids.

Koichiro Iketani
Koichiro Iketani is his best friend. He works at the gas station, so Kenji often comes over there to discuss about cars and races.

Itsuki Takeuchi
Itsuki is another worker at the gas station.

Takumi Fujiwara
Takumi Fujiwara works at the gas station along with Itsuki and Iketani.

Yuichi Tachibana
Yuichi is the boss of the gas station where Iketani works. He acts as a fatherly figure to the Akina SpeedStars despite Kenji not working in the gas station.
