Dilhade

Dilhade (ディルヘイド) is the demon kingdom.

History
During the Mythical Age, Dilhade was characterized by fierce infighting. Powerful demons fought each other for control of the country, while humans continued manipulating them to maintain the status quo. As a result, Dilhade was split into many territories, each ruled by a "king-class" demon. However, that changed when a promising young king appeared, Anos Voldigoad. He defeated the demons he didn't like, repelled the humans who attacked him, and made his name known throughout the kingdom. Some offered up their territories to the Demon King in order to gain his protection, while others antagonized him and were deprived of everything. Eventually, the Demon King Anos managed to unify the country.

When the Hero Kanon created a fake Demon King of Tyranny to protect Anos, he inadvertently gave rise to Pureblood supremacy. He only told Dilhade that the Demon King would reincarnate as a royal, but the royals took advantage of this to turn themselves into a privileged class. This split the country into two factions: the Royalists, who put pureblood descendants above everyone else; and the Unitarians, who wish for demonkind to be united regardless of parentage.

Upon the Demon King Reordination Ceremony, Anos abolished the segregation of demons with the support of several high officials and the Seven Demon Elders, a new order of egalitarianism was established between the royal and the mixed-blood demons. As a result, there are no longer distinctions between the two.

Society
Among demons, those who inherit the blood of the Demon King of Tyranny are called the Demon King's Descendants (魔王族). Within this group, individuals who marry other members of the clan, and have protected the purity of the Demon King's blood are called "royalty". But regardless of whether or not they are pureblood, any of Anos' descendants can attend the Demon King Academy, and only they can attend.

The academy exists to find the candidate most like the Demon King and train them to become future Demon Lords, officials who govern the districts of Dilhade. Because only royal demons can attain this position, the royal faction holds most of the power in Dilhade, and mixed-bloods have no say in how the country is run. However, even with this power disparity, the mixed-bloods live very comfortably, and Dilhade is ruled well.

Customs
Demons leave weapons without any magic as grave markers for the dead, as they believed that by doing so, the fallen could one day resurrect. The older the object, the more magic it possessed. Even if they rusted or weathered away, it went against their customs to repair them.

Laws
During the Demon King Reordination Ceremony, Anos installed new sacred rules for the newly reformed nation of Dilhade. When these rules are violated, no matter who the opponent is, the Demon King of Tyranny will risk his life to destroy them.
 * 1) This country will not tolerate injustice.
 * 2) This country will not tolerate malice.
 * 3) This country will not tolerate tragedy.
