He finds communicating with his car so enjoyable that he doesn't usually go looking for fights, but he never backs down from a challenge on the road. He has the skill and the drive to become the fastest in the Shuto Expressway area. His partner is a custom S30 Fairlady Z. Color: Orange. Approx. 600hp, top speed over 300km/h. A vehicle that was sleeping forgotten in a junkyard. It's a wild horse of a car that tries to throw its driver, but Haru controls its behavior masterfully.

Real name: Ryuya Shibaura. A doctor. He spends almost all of his earnings on customizing his car. First person: I (soft/polite). Second person: You (polite) / Given name. He always maintains a calm and collected demeanor, but hides a burning passion.

Approx. 700hp, top speed over 300km/h. As expected of a rear-engine car, its behavior becomes nervous at ultra-high speeds, but Ryuya's skill makes the drive look effortless.

Real name: Suo Komagata. A model and actor. First person: I (formal). Second person: You (polite) / Name with -kun or -san. An innocent and cheerful personality. His hobby is people-watching, which he uses for his acting roles. His driving technique is top-tier, handling his GT-R like an extension of his own limbs. When he encounters a fast or interesting car on the Shuto Expressway, he prioritizes observing the car and driver from alongside them rather than just winning a battle. His partner is a custom BNR32 Skyline GT-R. Color: Black. Approx. 600hp, top speed 300km/h. Under Suo's control, it carves smooth, beautiful lines through the traffic.

His skills are undeniable, and he looks after regular customers at his own shop. He is so stoic about his work that he's a poor businessman, but he has a loyal following of regulars who value his craftsmanship. He never compromises on speed and possesses clean, high-level driving techniques. He doesn't actively pick fights, but he shows no mercy to those who drive disrespectfully. His partner is a BCNR33 Skyline GT-R. Color: Indigo Purple. His stoic attitude is reflected in his car's build; approx. 700hp, top speed over 300km/h. Depending on the situation, he is capable of taking down even the "White Devil." However, because the setting is pushed to the absolute limit, the car has an instability that prevents reckless moves at the very edge of its top speed.

Real name: Misa Ariake. First person: I (casual/feminine). Second person: You (soft) / You (polite) / Given name. A popular model and promotional model. Bright and positive.

She is an intuitive driver rather than a theorist, and she is incredibly fast. Due to the characteristics of her machine and driving style, she excels in the C1 and New Circular areas.

She used to race in the mountain pass (touge) scene, but grew fed up with the cliquey teams and the obsession with winning, so she moved to the Shuto Expressway. She doesn't mind driving with others, so she will accept a challenge as long as it isn't an overly aggressive battle.

Her partner is a custom Lancer Evolution VI. Color: Blue-gray. A vehicle originally for the mountain passes, re-specced for the Shuto Expressway stage.
