Demon

Demons (魔族) 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 with 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, many demons are indistinguishable from humans, but some have prominent features like horns or wings.

Powers and Abilities
Demons have long lifespans that differ depending on lineage and heritage. The average lifespan is around three hundred years, but powerful demons can extend their life and are capable of living for thousands of years using magic. Demons 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 immunity to parasites and end up dominating them instead. The effect still works even if the parasite is a dragon or god, provided that an individual has sufficient magical power. Unlike humans, demons have no differences in ability based on gender. Despite all their strengths, demons are weak to anything holy such as holy swords, magic, and water.

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
Royalty (皇族), 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), or Hybrids, is an umbrella term for any demon whose blood is impure due to being mixed with another race, or bloodline apart from the Demon King's. Due to the discriminatory nature of the royal demons, mixed-bloods are shunned and 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 the Demon King's blood to inherit the aspects of the founding ancestor.
