Demon

Demons  (魔族, Mazoku) are one of the four main races, alongside Humans, Spirits, and Gods.

Overview
Demons are a warlike race with a long history of infighting, as they each fought for control over the territories of the demon nation, Dilhade. They follow a hierarchical structure where weaker demons would pledge themselves to a more powerful demon, either for protection or because they valued strength. When the leader was defeated and killed, it was common for the demons under them to become a disorganized rabble. Despite this, they were able to set aside their internal disputes when faced against an outside threat, such when the Demon King of Tyranny and the Four Evil Kings joined forces against the alliance of humans, spirits and gods.

Appearance wise, most demons are indistinguishable from humans, but there are some who naturally have horns or wings.

Powers and Abilities
Individuals from the demon race have really long lifespans, ranging from hundreds to over thousands of years depending on the demon. They are also stronger than humans in both magic power and strength, as they can withstand injuries that would otherwise be fatal to humans.

Demons also have an affinity for Demons Swords, though a demon would have to subjugate the demon sword and make it acknowledge them as their master.

Demon Royalty
Demon Royalty (皇族, Kōzoku), or simply Royals, are demons who directly descended from the Demon King of Tyranny and have kept his blood pure by marrying other members from the Demon King clan. After Anos created the Seven Elder Demon Emperors from his blood and magic, those seven used their own blood and magic to further create more pure-blood descendants, until they could have children naturally without the use of magic.

In modern Dilhade, they have a lot of political power and privileges due to a misunderstanding regarding the Demon King's prophecy of reincarnation causing blood purity to be held in the highest regard. As such, their duty is to leave behind pure-blood descendants; and a royal who has a non-pureblood child will be excluded from royalty, with the addition that their family members from 3 generations will also be excluded from royalty.

Mixed-Blood
Mixed-Blood (混血, Konketsu), or Hybrid Demons, is an umbrella term used for any demon whose blood is impure due to being mixed with another race, or full demons who are not descended from Anos. Due to the discriminatory nature of the royal demons, Mixed-Bloods are shunned and are excluded from major political decisions. While it is believed that they are weaker than royal demons, Anos states that it only takes one drop of demon king blood to inherit the aspects of the founding ancestor.
