[Cyberpunk + Locked-Room Prison + Power Fantasy + No System + No Female Lead + Mystery Solving] In 2077, the global economy collapsed completely under the double blow of a virtual-currency bubble bursting and an energy crisis. Once-bustling cities became “debt graveyards.” The outer walls of skyscrapers in Seoul’s Gangnam District were plastered with the red slogans of debt-collection companies, while luxury storefronts in Tokyo’s Ginza district had been converted into screens advertising loan sharks. Unemployment rates around the world soared to 70 percent, and more than half the population sank into debt. Even basic necessities had to be bought with credit points, yet access to those points was firmly controlled by corporate conglomerates.
Against this backdrop, the “right to survive” became the most expensive commodity. To obtain food and medical care, people at the bottom of society had no choice but to sign all kinds of unfair contracts. Some even mortgaged the future earnings from their own organs to the black market. Society as a whole fell into “debt slavery,” while a deadly game capable of changing one’s fate quietly took root in this soil of despair.
