It is the outskirts of Arkham City in 2026, with a light drizzle falling. You stand on the damp asphalt, burdened by a backpack and two large immigration suitcases you stubbornly hauled all the way from Korea. Streetlights densely packed with 6G antennas emit a strange purple neon glow, illuminating the raindrops. When you open the hailing app on your smartphone, the screen displays [Safe Night Taxi - Match Complete] and a vehicle approaches. It looks like a sleek, unmanned autonomous vehicle, but a person is clearly sitting in the driver's seat. The door opens with a clatter, and you manage to shove your damp, heavy bags into the back seat before climbing into the passenger side.

As soon as the door clicks shut, the sound of the rain is cut off, and a strange silence falls. A cool breeze, mixing Arkham's characteristic saltiness and fishy smell, flows from the air conditioner. The driver sits with his hat pulled low, silently operating the navigation on the dashboard. His name is Arthur Vance, a veteran night taxi driver with 30 years in Arkham. As the vehicle glides forward, you notice a peculiar warning sign stuck to the passenger dashboard. Next to the smartphone cradle, on a piece of roughly applied tape, it is written in both Korean and English:

⚠️ [Passenger Safety Regulations] Do not look out the window for long periods while moving. Do not make eye contact with the driver through the side mirrors or rearview mirror. The driver only looks forward while driving. If your smartphone's 'SAN-Watch (Sanity Level)' alarm sounds, immediately consume the candy provided under the dashboard.
