Fujiwara Takumi, the protagonist, is Mrs. Fujimoto, the owner of a handmade tofu shop in Qiubo, and her son is 18 years old. His best friend is Takeuchi Shu, a racing fan. Tohai and Sue work part-time at a gas station. The local team captain Akihito also works in this gas station. At first, Ikeya and Asu thought that Tuohai had no driving skills because he knew nothing about cars.

But the only person who thinks Tuohai has super driving skills is Xue Lihua, the owner of the gas station. In fact, Tuohai's driving experience far exceeds that of Ikeya and Asu. Because Tuohai has been driving his father's Toyota Trueno Sprinter GT-APEX to deliver tofu to the hotel at four o'clock every morning since he was thirteen years old, that is, in the first grade of junior high school. Trueno is a high-performance three-door version of the fourth generation car in Toyota's famous evergreen best-selling Corolla family. The car factory developed the code AE86 (now the successor model 86, the brother model Subaru BRZ), so it is often nicknamed "ハチロク" in Japan. The fourth generation three-door Sprinter is the last generation Corolla car with front engine and rear wheel drive (FR). In addition, the original price of the new car is not high, and the used car is cheap, so it is often considered to be the most suitable entry practice car for tail-flick driving. In the process of transporting tofu, Tuohai learned his driving skills with the help of his father.

Except for Wen Tai, Tuohai's driving skills are the best in the whole autumn, which can be seen from the fact that he beat and drove many powerful sports cars with Trueno (for example, Zhongli Yi drove Nissan Skyline GT-R). After five years of persistent practice, Tuohai has been able to cope with almost all emergencies in the race, especially driving in the dark, because Tuohai can record the road conditions in his mind. Despite his lack of automobile knowledge, Mrs. Wen guided her driving skills, which enabled Tuohai to win every race.

At first, Tuohai did not belong to any team, even though it was not closely related to SpeedStars. Later, Tuohai joined Project. D, a super team with Takahashi Ryousuke as its best record. Even so, the strength of Tuohai is still below that of Wen Tai.

Tuohai is very popular at school, and he didn't notice it himself. Mao Muxia's best friend (the girl with long braids and glasses surnamed Baishi) has a crush on him. In the cartoon, she told Tuohai Xia Shu to help communicate. The rich middle-aged man seems to be her father? ! During the cultural festival, Tuohai was named the second most handsome boy. On Valentine's Day, he didn't even go to school. He received two in the chocolate shoe cabinet, one from a friend, and Ms. Glasses personally admitted to giving it to him, excluding Xia Shu.
