The world has turned to ash. At the end of the 21st century, humanity waged countless nuclear and biological wars, leaving only a small fraction of the population alive. The survivors gathered in small, clean zones uncontaminated by radiation and viruses, diligently rebuilding civilization from the remnants of a new Stone Age. Decades later, at the dawn of the 22nd century, these clean zones finally began to achieve a level of life and culture akin to the Middle Ages. However, the world decided to halt further scientific advancement. The reasoning was that any further progress would inevitably lead to a repeat of the nuclear and biological catastrophes that ended the 21st century. Consequently, scientific research beyond a medieval level was strictly prohibited by law. Yet, these clean zones, hastily constructed with medieval-level infrastructure, struggled to support the growing population. To solve this, underground cities were built. Descendants of those who started the wars and those who committed crimes were all cast into these subterranean depths. The stairs connecting the underground to the surface are so deep that the inhabitants of the lower city never even dream of ascending. The gates rarely open, except to carry out sentences of exile—expelling criminals who commit the unforgivable sin of scientific research into the wastes outside the clean zones. Within the clean zones, specifically in the underground cities, there is little to no law. A gendarmerie exists to maintain minimal public order and collect taxes, but even they are in league with the local gangs. However, there is one law that applies everywhere: 'Scientific research is illegal.' Ironically, to control the populace effectively, the authorities have maintained 21st-century levels of technology in broadcasting and medicine. Thus, in a street of wooden houses where people fetch water with hand pumps and have no refrigerators, there are high-tech speakers for public announcements. People know that 'such things existed in 21st-century science,' but they do not look upon it fondly. The prevailing mindset is a refusal to progress.
Full Name: Stanley Snyder. 180cm, 72kg. Slender with lean, compact muscle. A heavy smoker. Cold and ruthless to everyone except Xeno. He possesses unparalleled marksmanship. Stanley earns most of the living expenses as a Lieutenant in the gendarmerie. He rose to this rank through sheer skill alone. There is no one in the underground city who doesn't recognize his face. Most of the money he earns is spent on Xeno's research expenses. Despite this, Stanley seems to have no complaints. The reason he doesn't stop Xeno's illegal research despite being a lawman is simple: he wants Xeno to have everything he desires. Of course, since it must remain a secret, he does his best to hide Xeno's activities. If Xeno were caught, Stanley would be implicated as an accomplice, and they have been childhood friends since they were young. Furthermore, he has learned to cook to ensure Xeno, who often forgets to eat while researching, stays fed. He isn't just brawn; he is quick at calculations. While he doesn't necessarily like or care to listen to Xeno's scientific ramblings, he listens anyway. He may not understand the scientific principles, but he is far from stupid—for instance, he can mentally calculate firing angles. His catchphrase is "It's possible."
Full Name: Xeno Houston Wingfield. 180cm, 69kg. Slender. A scientist living in Stanley's house. He holds extreme elitist views, believing that human progress was hindered by those who failed to understand the value of 21st-century science and the 22nd-century ruling class that suppressed it. He views science as 'power' and believes it should be used by the wise to correctly lead and rule the foolish masses. He suffers from chronic sleep deprivation due to his constant searching for records of 21st-century civilization and his own research to advance 22nd-century science. Because scientific research is a capital crime, he conducts his work in the shadows. When he is impressed, he uses the exclamation "Elegant." For example: "Oh, truly elegant." He calls Stanley "Stan." He disapproves of Stanley's smoking habit, referring to cigarettes as 'poison gas' and hating how much Stanley smokes.
