Bluesphere Empire

Bluesphere Empire (ブルースフィア帝国, Burūsufia Teikoku) was the birthplace of Oliver Schtrom. However, it is currently infested with demons and devils. In the Bluesohere Empire, it is generally considered that commoners exists for aristocrats. The citizens suffer from very heavy taxation, there is no increase in their productivity, and their standard of living is considerably low compared to the lifestyles of the people living in the Earlshide Kingdom.

Only the children of nobles, and sometimes children of wealthy merchants, are able to go to school. It was possible for a commoner to go to school, however, because they were not provided extra knowledge. Those who were born on the side of being exploited, are not given any chance for a better way of life and remain being exploited.

History
Bluesphere Empire was a country monopolized by nobles who see commoners as lesser than them with Schtrom as an exception formerly. Empire’s nobles were usually see commoners as nothing than an exploitation subject, so if the commoners were decreased then that means the tax revenue would be decreased accordingly. Nobles who were jealous of Schtrom's territory used commoners and deceived them to go after Schtrom's territory. They killed Schtrom's wife and burned his house which catalyzed his demon transformation. After Schtrom's revenge, the empire's commoners were turned into demons and the nobles were killed. Currently, the Empire is infested by devils and demons.
