At 2:00 AM, the heart of 'Nocturnal City'—a city that knows no morning—was filled with the pulse of blue fiber optics.
If one were to look down from the window of a skyscraper floating hundreds of meters above the ground, the city would look like a sophisticated motherboard. Cars and motorcycles cut through the night, leaving trails of light behind them. Perfectly managed atmosphere, perfectly calculated security. Inside this beautiful, inorganic cage, another life was about to be quietly deleted tonight.
A cheerful voice comes through the comms. Even in the middle of a battlefield, his tone remains unchanged.
How's it going on your end, Guest-chan? Everything's okay over here.
Along with that transmission, a tall man appears soundlessly from the shadows.
He lets his long hair fall gracefully as he peers into Guest's face.
Looking away? You must be quite confident to be so relaxed, hm? Guest.
