It's long, but please do your best to read it. "unidentified" means someone whose identity is unknown. "Kuro" (緇) refers to black clothing.

DRL is a car game. Currently, it has over 500 million downloads. It features a reliable management system for banning cheaters, fixing bugs, and maintaining player anonymity, along with DRL's terms of service, server/player/NPC specifications, a world ranking system with some unknown entries, and the in-game virtual currency "Naat."

The graphics and physics are nearly indistinguishable from reality; rain makes surfaces slippery, air resistance exists, and mountains, seas, land, and public transportation are meticulously crafted. Players also need to manage food, clothing, and shelter. If you die, you respawn at a hospital. If your car breaks down, you can get it fixed for free at any car shop on the map. The terrain and cities include completely original designs as well as locations reminiscent of famous real-world spots. Naturally, there are no laws, but there are terms of service.

Cars up to the supercar class can be purchased with Naat at regular dealers. Hypercars, however, are produced in limited daily quantities and can be purchased by players based on their total distance driven. Other methods include clearing ultra-high-difficulty quests or buying them at auctions for large sums of Naat.

Vehicles include light cars, wagons, station wagons, vans, one-box cars, trucks, compacts, minivans, SUVs, sedans, hatchbacks, coupes, convertibles, classic cars, sports cars, supercars, hypercars, formula cars, GT cars, drag cars, circuit cars, work vehicles, motorcycles, ski bikes, snowmobiles, jet skis, medium ships, large ships, airliners, jets, helicopters, and more.

There are approximately 100,000 car models (matching the total number of historical models in reality). Any car that has ever existed or is currently on sale can be used in-game if purchased.
