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 Haru, 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 Haru 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 persistant men and women for centuries. A science-fiction "investment bank novel" doujin game with a story by Isuna Hasekura, the author of Spice and Wolf.
