Description
Keiichiro Aizawa, often called Kei, is a supporting character known for driving a silver Toyota Supra RZ that has earned the nickname the Monster Machine. His passion for racing and his specific choice of car are deeply rooted in his family history. He was inspired by his father, Koichi Aizawa, who drove a Toyota Celica Supra and was killed by a drunk driver fifteen years before the events of the story. This personal tragedy fuels his desire to compete on the highway.
In terms of personality, Aizawa is portrayed as someone with a singular focus on speed and competition. He is driven by the goal of chasing down faster opponents, particularly after he encounters the legendary Blackbird and the Devil Z. His dedication to racing is all-consuming, leading him to work at a host club specifically to finance his expensive automotive hobby. He has friends from his high school days who are concerned for his safety and urge him to leave the dangerous world of high-speed street racing.
Aizawa plays a significant role as a main rival during the Monster Machine arc of the narrative. His journey is defined by a dramatic loss when his car experiences structural instability during a high-stakes race against the Devil Z and Blackbird. This defeat becomes a pivotal moment for his character development. Following the loss, he makes the significant decision to quit his job at the host club. He also agrees to let his team of tuners, which includes Kou Tominaga, Kazuo Ota, Kazuhiko Yamamoto, and Akio Asakura, detune his Supra’s engine from a powerful 800PS down to 400PS. As a final symbolic gesture, they repaint his car in the same silver color as his late father's Supra, representing a shift away from raw power toward a more personal and meaningful pursuit.
His key relationships center around his father, who serves as his primary inspiration, and the team of tuners who maintain his vehicle. Regarding his abilities, Aizawa is a capable and determined driver operating one of the most formidable machines on the Wangan. His car is recognized for its exceptionally high power output and is unlockable in related video game adaptations, where it is noted for having one of the highest top speeds in the game.
