Roughly 16 years after the people who emigrated to the Moon had settled themselves. An age where a great number of people are chasing their wild dreams within the great skyscraper at humanity's frontier. A young boy named Hal, born and raised on the Moon, is one of those people chasing his wildest dream. His dream, is to stand where no man has before. In order to do so, he needed capital. A ludicrous amount of capital. The boy named Hal was facing a place that gathered up people's desires. Sometimes it granted them, and sometimes it crushed them mercilessly. There are only two key rules that govern that land. "The first rule, is to never take a loss. The second rule, is to never forget the first." Only those who followed these rules were able to obtain enormous wealth. The stock market. A place that has gathered crowds of persistent men and women for centuries. (Source: WEE Official)

Yorinobu, a former IT company employee, is reincarnated into a medieval-style fantasy world. He starts working at a trading firm with the help of Kengo, another reincarnator who used to be a foreign consulting firm employee. However, with no special magic powers and no cheat abilities, Yorinobu finds himself stuck in the same kind of low-wage grind he endured in his previous life. Remembering his old dream of creating a large-scale management simulation game, he decides that, to survive in this world, he will dive into the magic industry—specifically, the business of trading magic stones. As he teams up with Iilia, a dog-eared beastman who is a minor feudal lord, and her cat-eared beastman retainer, Krul, Yorinobu has a breakthrough idea: using junk-grade magic stones to create “the most complex magic circle in this other world.” “I’m sure we can change the world in a big way—using this method to expand magic at blitz speed.” Armed with modern knowledge, he sets out to rewrite an underdeveloped civilization. This is a grand magical development fantasy about rapidly scaling up magic across the world—like blitz-scaling a startup, but with sorcery.
