Takumi Fujiwara and his brothers Keisuke and Ryousuke Takahashi founded Project D, a racing crew that seeks to push their driving talents beyond their home prefecture. The trio uses the internet to issue challenges to rival teams and to publish race results. Under Ryousuke’s management, Takumi battles in downhill races with his AE86, while Keisuke faces competitors uphill. Their primary adversaries include the Seven‑Star Leaf (SSR) and Todo‑juku.
