Shuichi Matsumoto is best known as Takumi Fujiwara's personal mechanic, keeping the legendary AE86 in fighting shape. He likely holds a chief mechanic position within Project D as well, though his exact role remains somewhat unclear depending on the source material.
During Project D's expeditions, Matsumoto drives support van #3—essentially keeping the team mobile and ready. Early on in the manga, Ryosuke tapped him to tune up his FC in preparation for a showdown with Rin Hojo, which speaks to the trust placed in his skills.
