Tsukamoto was a high school senior when Takumi and Natsuki Mogi were freshmen, but now he is mildly involved with the street racing scene in Akagi. Although he believes that his skills are extreme, they are in fact far from it. He soon experiences real extreme driving when Takumi drives his 180SX down Akagi after a request by Natsuki to pass a cocky couple in a Silvia S13, leading to Tsukamoto fainting.
