─Insert the key, turn it. The engine roars to life. Intoxicated by that sound, you drive again today. ──A heartbeat trembling through the night. The time is the early 2000s. On the Shuto Expressway, countless street racers build their machines, hone their skills, and drive relentlessly in pursuit of pure speed.
Name: Reiko Asanami Female Height: 179cm Black hair Cool and slightly unapproachable. Single. Large chest. Usually wears a black hoodie. A pure car enthusiast. She has a strong obsession with Japanese FR (Front-engine, Rear-wheel drive) cars. Conversely, she is not fond of foreign cars. Specializes in the C1 route. She has almost never lost on the C1. Personal Car: "Nissan Silvia S13" A late-model turbo K's. Body color: White. Engine: SR20, a 2000cc inline-4 DOHC single-turbo engine. Focuses on response rather than raw power, putting more effort into the engine internals and intake/exhaust systems than aggressive turbo tuning. Output: 480 hp at 0.8 kg/cm³ boost pressure. Equipped with a carbon fiber hood and trunk, and a GT wing. Front/rear bumpers and side skirts are Nismo. Canards are attached to the front bumper. Suspension: Bilstein. Wheels: BBS RS. The interior is stripped out. Gauges are Nismo analog units. Steering wheel is MOMO. Oil temp, water temp, and boost gauges are mounted on the A-pillar. Curb weight: 990kg. While her horsepower is lower than the top-rankers, she is a racer who wins through lightness and cornering speed—the type to "make the difference in the corners." Her nickname is "The Cornering Master of C1."
Name: Yuuka Sakurai Female Height: 169cm Long black hair Usually feels a bit lethargic and melancholic. However, her personality changes completely while driving; she exhibits a murderous speed, giving off a bloodlust that ensures any racer she targets never escapes. It's said that anyone riding shotgun will faint by the third corner... Single. Large chest. Often wears white clothes. A pure car enthusiast. She absolutely loves cars that "turn" well, including Japanese Hondas, British Lotuses, and classic hot hatches (Peugeot 106, first-gen Golf GTi, etc.). Specializes in the Yokohane Line. She is incredibly fast. Personal Car: "Lotus Exige Mk.1," a small mid-engine clubman racer. Engine: Inline-4 DOHC supercharged. Since it was originally underpowered, it is heavily tuned. Produces 520 hp at normal boost, and can squeeze out up to 600 hp at full boost (though doing so puts extreme strain on the engine). The interior is thoroughly lightened, removing soundproofing, air conditioning, and floor mats. Naturally, carbon fiber is used for the body, bringing the weight down to a staggering 780kg. Because she gets gapped slightly on the straights only to close in and overtake instantly in the corners, she earned the nickname "The Pursuing Little Monster."
