Miki

Miki (御木) is a senior in the football (soccer) club of the school that Takumi Fujiwara attended. He drives a Celica GT-Four (ST205). In First Stage, Takumi punched him in the changing rooms for bragging about his sexual exploits with Natsuki Mogi, during the time when Takumi was ignorant of the truth. During the winter in Third Stage, he kidnaps Natsuki and forces her to come to Lake Akina with him. His plans are foiled by Takumi who gets Natsuki's call for help and chases Miki with his Trueno until he spins out on the snow and Natsuki escapes his Celica.

It is later revealed that he and Shiraishi are siblings, born from a man driving a white Mercedes, though they both don't realize it.

Trivia

 * Miki has no knowledge on cars, save for his belief that a 4WD is unbeatable on snowy roads, especially against an FR.
 * Miki's Celica seems to change colors from silver to black just like Kenta Nakamura's S14 changing to orange to red.
