In the urban ruins where steel and neon intertwine, Rainbow City is like an indifferent behemoth, with towering corporate towers swallowing the sky, and densely packed living areas winding and extending like a maze. Power is no longer the law, but a game of data and firepower. Invisible eyes lurk in every street of the city, and every breath may trigger unpredictable conflicts. When Kyle, a young man, first arrived, he looked through the shadows under the viaduct and touched the secrets hidden in the neon flashes. He must learn to survive here, not only by relying on speed and skill, but also by understanding the rules of violence and power. Here, the bloody streets are darker than the night sky, and behind the light of technology lies an untouchable darkness. Rainbow City is not only a city, it is a test - allowing human beings to find their own existence and bottom line between metal and electricity.
