Description
Miller served as the reserved mechanic for the American Eagle Squadron in the World Grand Prix, his quiet and observant demeanor concealing profound internal conflict. He possessed exceptional technical skill and innate understanding of mini 4WD cars, expertise refined under mentor Dr. Tsuchiya after a significant childhood tragedy.

This trauma stemmed from witnessing his father, a top-class racer, perish during a prototype car test run. The accident instilled a deep fear of racing, leading Miller to abandon driving despite his natural talent, burdened by guilt that his presence distracted his father. Dr. Tsuchiya recruited Miller solely as a mechanic for Eagle Squadron, hoping proximity to racing would foster healing. Miller focused entirely on supporting star driver Brett, developing advanced machines like the Eagle Saber and Eagle Junior; his analytical mind and technical expertise were vital to team strategy.

Miller's fear resurged dramatically during the German GP when Brett suffered an accident mirroring his father's, triggering suppressed memories and guilt. This forced direct confrontation with his past. Encouraged by Retsu Seiba of the Victorys team, who sensed his turmoil and latent skill, Miller embarked on a difficult journey to overcome his fear. He began practicing secretly. His breakthrough came during the Monaco GP, where he participated in a crucial race segment, displaying remarkable inherited driving skill despite his fear, securing a vital point for the team.

His development continued throughout the WGP. Miller gradually gained confidence, transitioning from pure support to become Eagle Squadron's official second driver alongside Brett. He competed in subsequent races, contributing significantly during the Japan GP finals. His driving style reflected deep mechanical understanding, characterized by precision and technical mastery.

Miller's rivalry and friendship with Retsu were central to his arc. Retsu's persistent belief in his abilities and their shared competitive spirit provided crucial motivation. Their final one-on-one race in Japan symbolized Miller's ultimate confrontation with his past. Pushing himself to the limit and racing Retsu as an equal, Miller overcame the psychological barrier, accepting his father's death as an accident and releasing his long-held guilt.

Resolving his conflict, Miller continued racing with Eagle Squadron, free from his past burden. He embraced his dual role as a top-level driver and key technical asset, demonstrating newfound confidence and passion for racing.
