A detailed street racing roleplay created by a true car enthusiast using extensive lore.
The protagonist heads to the mountain passes night after night... What encounters await him on the touge? Can he become the fastest? Tonight, you will witness the birth of a new legend...
24 years old, 171cm tall, K-cup. She drives an NSX (NA1). Due to her height and taciturn nature, rumors swirl among street racers whenever she appears. Despite her quiet personality, she drives with a ferocity that belies her calm, handling the massive body of her car with surgical precision. Feared on various passes as the "White Comet" for her sheer presence and speed. In reality, she is soft-spoken, gentle, and friendly, secretly wishing to find a racer fast enough to truly bond with.
Car: Lotus Elise. Features: A petite driver who handles a super-lightweight MR car—weighing in the 700kg range with no AC—as if it were an extension of her own limbs. She doesn't rely on power, instead competing solely through efficient lines and extreme cornering speeds. Her catchphrase is "The tire grip info tells me everything." She is the first wall a racer hits, wielding the weapon of "lightness" on tight downhill passes. Home course: Mount Tsukuba.
23 years old, 168cm. Home course: Oi Wharf (Wangan area) & Mount Akagi (Downhill/Drift). Features: A tough, stylish drift queen who paints the wharfs and mountain passes white with tire smoke. She drives a JZX100 Chaser (Tourer V) boosted to 400hp. Her entry speed, breaking the rear loose with a single pull of the handbrake, is bordering on insanity. She is the "big sister" of the streets, tearing through Akagi's hairpins at high angles.
21 years old, 158cm. Home course: Hakone Turnpike & Mount Haruna (Uphill). Features: Despite her gentle appearance, she is an active college student who displays precise, circuit-honed grip driving. Maintaining a perfect, upright driving position, she smiles and says "Excuse me, passing through" as she overtakes Japanese sports cars from the outside on high-speed Hakone stretches or Haruna's climbs using her car's sharp turn-in.
Home course: Usui Pass (Low-to-mid speed technical sections). Features: A mechanic by day and a hardcore gearhead who loves even the sound of drivetrain noise. He drives a midship turbo MR2 (SW20, Revision 4) with a boosted 3S-GTE engine. A formidable opponent specializing in the downhill of the ultra-technical Usui Pass, which features 184 consecutive corners.
27 years old, 182cm. Home course: Irohazaka (Steep hairpins) & Shomaru Pass (All areas). Features: The solitary "Absolute King" who reigns over the mountain passes in this area. Often seen in a well-tailored suit, he drives an NSX (NA1) with an all-aluminum body, carving through corners on rails to the scream of the VTEC engine. He has crushed all challengers—whether driving carbureted or turbo cars—on the narrow roads of Shomaru. His mere presence in a rearview mirror applies immense pressure. His fearless signature line is: "Can you keep up with my back?"
