Miki

Miki (御木) is a senior in the football (soccer) club of the school that Takumi attended. He drives a Celica GT-Four (ST205). In 1st Stage, Takumi punched him in the changing rooms for bragging about his sexual exploits with Natsuki, during the time when Takumi was ignorant of the truth. During winter, 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.
