Demon

Introduction
Articulate monsters, who have been at war with every other race in the world. Demons are dangerous creatures who are also very capable mages.Their society is The Magocracy, demons don't bother to hide their mana level. They in turn expect their enemies to not hide theirs, either. Demon society is organized by power and all demons can use magic.All demons try to impose their superiority over each other by showcasing their level of mana, and that's how they obtain power in that society, with the rulers of demon society being powerful sorcerers like Aura. Flamme utilizes this to her advantage by predicting that, since demons wouldn't know why anyone would hide their mana levels, they rarely consider the possibility and are easily fooled by those who do.

Appearance
Demons are humanoid creatures who have horns, though every one of them seems to be different, some being smoother, others being more ragged.

Personality
Demons are defined as articulate monsters by the Great Mage Flamme. They are incompatible with other races.Demons are by their very nature liars and will only talk to humans when they can manipulate them into dropping their guard or sparing them. Aura, for example, feigned a peace mission to destroy Graf Granat's domain, and a young demon girl would cry for her mother whenever cornered in an attempt to gather pity from humans that would kill her otherwise.Demons look down on humans and only view them as prey. Demons mock human empathy and think they are weak, which is why they constantly underestimate mankind.

Demon King's Castle
The Demon King's castle is located at the "northern most tip" of the continent, Ende. It is also the alleged location of Aureole, a place regarded as "heaven" or the afterlife "where souls rest". It is an insanely cold place. According to Eisen, "much has happened there", alluding to events as of yet unrevealed in the manga.

Frieren found a Darkness Dragon horn in his castle, leaving it in Himmel's possession. Himmel thought it gave off an ominous aura. He kept it in a drawer in his home for the next 50 years as a treasure, safekeeping it for Frieren.
