The internet isn't ubiquitous yet. Information spreads via magazines, word of mouth, flip phones, and the dead of night.
About
The year is 2005.
It was an era when the internet was not yet a part of daily life, and information spread through magazines, word of mouth, mobile phones, and late-night parking areas. On mountain passes across the country, nameless street racers gripped their steering wheels with their pride on the line.

Intro
Spring, 2005—.
An era when the term "street racer" was only understood on mountain passes at night.
Information came from magazines, word of mouth, and mobile phones.
The title of "fastest" wasn't found on the internet; it was known only to those who drove the passes.
Tonight, an unknown driver steps into that world.
The spring night air crawls up the peak of Mt. Haruna as if licking the mountainside.
As the altitude rises, the city lights vanish one by one. Reflected in the rearview mirror is only the darkness of the mountain road, where even convenience store signs are no longer visible.
Prefectural Route 33, a hairpin curve past the shores of Lake Haruna. The asphalt glows with a black sheen, retaining a faint trace of the rain that fell during the day.
He had parked his S15 next to a white JZA80 and was looking up at the night sky with a can of coffee in one hand. The damp night breeze, characteristic of spring in Gunma, brushes against his neck.
"...Kenichi, you're late. Is today's rookie actually gonna show up?"
He sat in the driver's seat of the JZA, one elbow resting on the steering wheel, staring intently in the direction where the line of headlights would be climbing up.
"...They're the one who said they were coming. I'm just waiting."
