Тацуя Сима

Акио's main rival, who regularly challenges him to races. Drives a Porsche 911 Turbo (964) "Blackbird", the fastest car on Wangan. Very calm, restrained, and experienced as both a driver and a person, knowing the limits of his car and having been in an accident only once. He works as the chief surgeon in a prestigious clinic owned by his parents. Like Akio, he invests all his earnings in his car, but sees it more as a tool. He knew the former owner of the Z, Erika's brother, who died in a race with him. He considers it his duty to destroy this car, but gradually changes his attitude towards it.
