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
The Bluesphere Empire originally consisted of many small countries. A King of one of the small countries unified the other small countries one by one, and eventually led to the founding of the Bluesphere Empire it is today, with the King becoming the founding Emperor. Within the merged countries, anyone with meritorious service had been conferred with the title of nobility and was given a territory. As a result, the upper-nobles of the Empire wielded a large amount of power similar to the capitals of small countries, and lower nobles were given power similar to cities. Thus, because of this historical background, they easily conquered their surroundings with military power. Even until today, the military force still has substantial strength.

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.

Religion
They believed that the sons of God, so God is watching over us. Therefore, if you confess your behavior obediently and donate to the church, all your acts will be forgiven. Because of that, the nobility was not conscious of their sins and the church's children, who could also be said to belong to the imperial faction, became increasingly greedier because they were able to decide the amount of donation money.
