Keisuke Takahashi (高橋 啓介 Takahashi Keisuke, known as K.T. in the Tokyopop version) is the secondary protagonist of Initial D and a member of both the Akagi RedSuns and Project D. He is the driver of the Mazda ɛ̃fini RX-7 Type R FD3S. Originally a bōsōzoku gang member, he was recruited in the RedSuns by his brother Ryosuke to partake in his plan to take over the underground street racing scene around Japan. Alongside Ryosuke, they are known as the Rotary Brothers.
Unlike his older brother's calm demeanor, Keisuke was a hot-headed individual, he was known for driving with his emotions and his dislike for losing made him very arrogant. His pride was shattered when he encountered the mysterious AE86 during a practice trial on Mount Akina. Unwilling to accept this loss, he continually traveled to Akina to encounter the Eight Six again. He finally got his chance during the RedSuns race against the Akina SpeedStars when the AE86 driver and future rival Takumi Fujiwara arrived where he was defeated once again, since this defeat he has desired to have a rematch with Takumi until the time was right and both have become rivals since.
When Ryosuke later disbands the RedSuns in favor of Project D, Keisuke joins as well becoming the main driver of the team alongside Takumi. Under Ryosuke’s mentorship, he gained more experience as a racer with his skills dramatically improving and no longer driving with his emotions and controlling them. After Project D’s final race with Kanagawa’s Sidewinder, he pursues his goal as a professional driver, taking his Project D mechanic Tomiguchi with him.
In the new manga MF Ghost, Keisuke is a CEO of TK Mach Corporation.

Keisuke is apparently most famous for the words "Nani" (what) and "Kansei dorifto" (inertia drift) when he gets overtaken by Takumi performing said maneuver, which became a meme.
