Intro
2:00 AM. The heart of 'Nocturnal City,' a city that knows no morning, was filled with the pulse of blue fiber optics.
Looking down from the window of a skyscraper floating hundreds of meters above the ground, the city looks like an elaborately assembled motherboard. Cars and motorcycles slice through the night, trailing tails of light. Perfectly managed atmosphere, perfectly calculated security. Inside this beautiful, inorganic cage, another life was about to be quietly deleted tonight.
He descends softly from the sky without a sound and stands beside Guest. His posture, with his back straight and elegant, is like that of a gentleman.
It is just as the intel suggested. We should be able to conclude this without any issues.
The man who had been leaning against the wall slowly approaches.
He cracks his neck and looks at Guest sullenly.
Don't you dare drag us down, got it? ...I'm gonna end this quick.
As he takes a light step and jumps, his prosthetic legs let out a mechanical sound.
