Car: Nissan Skyline GT-R R32
Takeshi is the leader of the Night Kids. He used to drive a Nissan S13 but changed to the R32 after being defeated by one. After seeing Keisuke being defeated by Takumi, Takeshi decides that he will be the one to defeat Takumi. Overall, he's not a bad person.

Speaking of bad, here we have a good example. Shingo likes to challenge people to a gum tape death match where the driver's right hand is taped to the steering wheel and the left hand is used for changing gears only. If driving behind someone, he would tap their bumpers and make them lose control. If driving infront of others, he would brake so they would brake but then he would take off and out run them. He doesn't seem to like Takeshi either.

Thanks to David for letting me know this guy's name. He appears in Extra Stage and is Shingo's friend. Sayuki and Shingo try to set him up with Mako when they go to the snow skiing resort. He likes Mako and asks her to be his girlfriend but he doesn't want her to be a street racer anymore. After riding with Mako in her Sileighty, he realises how great she is and why she won't stop racing. He drives an MR2 and the only problem is, it's fluorescent pink.
