The demons (mazoku) in Frieren: Beyond Journey’s End are not something you can simply label as “evil monsters.”
They speak the same language as humans, and at first glance, they even seem capable of negotiation.
But at their core, they are fundamentally different from humans—and that gap is what makes them truly terrifying.
To humans, demons are predators.
They do not use words to understand one another, but to lull their prey into a false sense of security before striking.
That’s why Frieren’s stance is always clear and unwavering: if you find a demon, you kill it.
There’s no room for emotional hesitation, and that consistency is a key part of this series’ worldview.
In this article, we’ll break down the demon race by covering their core lore and then organizing the major demon characters—based on both rank and individual roles—from anime Season 2 through the latest volume of the original manga.
Basic Information About Demons (Mazoku)
Demons are best described as “monsters that can speak human language.”
That alone sets them apart from ordinary monsters—but speaking doesn’t mean understanding.
Demons lack human values such as empathy, guilt, or familial love.
What looks like emotion is often nothing more than imitation.
Crying, apologizing, even begging for mercy—these aren’t expressions of feeling, but combat tactics.
Their use of magic also sets them apart.
Most demons specialize in perfecting a single spell to an extreme degree, rather than learning many spells like human mages.
This is why it takes humanity so long to analyze demon magic and develop countermeasures: their spells often exist beyond conventional magical logic.
Demon Biology and Behavioral Traits
Demon Magic and Mana
The higher a demon’s rank, the greater their mana—and the more dangerous their magic.
At the level of the Shichikuzuken (The Seven Sages of Destruction), it’s not unusual for a single spell to be capable of destroying an entire city or nation.
Macht’s golden transmutation is a perfect example.
Another key trait: when demons die, their bodies dissolve into particles of mana.
No corpse remains.
As a result, demons have little to no concept of funerary rites, which only deepens the sense that they are fundamentally alien to humans.
Physical Abilities
Demons aren’t just backline spellcasters.
Some individuals are terrifyingly powerful in close combat as well.
High-ranking demons, such as general-class fighters, can go toe-to-toe with warriors on Eisen’s level.
Assuming “demons = fragile mages” is a quick way to get killed.
Personality and Behavior
Demons are highly rational creatures.
Concepts like protecting the weak or respecting life simply don’t exist for them.
At the same time, they are intelligent.
They understand human weaknesses—emotion, language, personal bonds—and exploit them without hesitation.
Demon Appearance
Mostly Human-Like
Most demons closely resemble humans.
The most obvious giveaway is often their horns—but even that isn’t foolproof, since some demons can conceal them.
Never assume safety based on appearance alone.
Non-Human Forms Also Exist
There are also demons with clearly inhuman appearances, and those tend to be especially dangerous.
Kvarl, for instance, looks less like a demon and more like a full-fledged monster.
Demon Society and Structure
No Concept of Family or Packs
Demons rarely form relationships resembling families.
They may cooperate, but only for mutual benefit.
Following a stronger demon isn’t loyalty—it’s a survival strategy.
Organization and Hierarchy
When the Demon King was alive, demons were unified as the Demon King’s Army.
Now, they act independently and sporadically.
That lack of central control is precisely what makes them frightening—powerful demons roaming freely, acting on their own whims.
Major Demon Characters Overview
Let’s start with a high-level overview before diving into detailed breakdowns.
Warning: The following sections include major spoilers, including character deaths.
Shichikuzuken (The Seven Sages of Destruction) – List
| Name | Title | Overview |
| Schlacht | All-Knowing | A strategist who controls the battlefield through foresight |
| Aura | the Guillotine | A tyrant who commands armies via domination magic |
| Macht | of the Golden Land | A top-tier demon who can doom entire cities |
| Böse | the Undying | A defensive powerhouse with overwhelming barriers |
| Grausam | the Miracle | Abilities unknown, likely mental-based |
| Three Others | Unknown | Implied to have died fighting the Southern Hero |
The Seven Sages of Destruction – Individual Breakdown
Schlacht the All-Knowing
Schlacht isn’t so much the “boss” of the Seven Sages as he is the Demon King’s chief strategist.
With abilities akin to future sight, he continuously identifies winning paths before battles even begin.
What’s especially unsettling is that Schlacht likely knew he would eventually die.
Even so, he continued to fight—suggesting that his actions were meant to secure the future of demonkind as a whole.
Because Schlacht has very few direct appearances, his presence feels like lingering foreshadowing.
Even after his death, it feels as though his plans are still in motion, casting a long shadow over the story.
Aura the Guillotine
(Dantoudai no Aura)
Aura is one of the clearest representations of how terrifying demons truly are.
She looks cute, speaks calmly, and acts confident—but beneath that is a pure tyrant.
Her signature spell, Scales of Obedience, forces eternal submission based on mana comparison.
In simple terms: if she has more mana, she automatically wins.
Aura’s downfall lies in her arrogance.
She fails to realize that Frieren is suppressing her mana, assumes superiority—and the moment she does, she loses.
Her death is brutally symbolic:
the one called “the Guillotine” is the one who loses her head.
It’s a moment that drives home the series’ core message—demons are shown no mercy.
Macht of the Golden Land
(Ougonkyo no Macht)
Macht stands apart even among the Seven Sages and is treated as a true top-tier threat.
His magic is absurdly powerful: anything he touches turns to gold. Entire cities can be rendered uninhabitable.
What makes Macht fascinating is his interest in humans.
He attempts to understand the human heart—not through empathy, but through study and observation.
His relationship with Denken is especially important.
Macht is one of the very few demons who taught magic to a human.
Because of this, the Golden Land arc pushes the question “Can demons and humans ever coexist?” to its absolute limit.
The conclusion is deeply ironic.
A demon who couldn’t fully look down on humans is ultimately defeated by their stubborn will and persistence.
Macht is powerful not just in strength, but as a thematic symbol.
Böse the Undying
(Fushi naru Böse)
Böse leaves a strong impression despite limited screen time.
His title suggests immortality, but in reality, his strength lies in barriers so powerful they were considered unbreakable.
What matters is how those defenses fall.
Frieren herself states that humanity cannot break them alone—yet the Hero’s Party does, through coordination.
The decisive blow comes from Himmel.
Böse underestimates him, focusing only on Frieren—and pays the price.
It’s a perfect illustration of demon arrogance versus human adaptability.
Grausam the Miracle
(Kiseki no Grausam)
Grausam remains largely shrouded in mystery.
However, hints suggest abilities related to the mind—dreams, illusions, or memory manipulation.
Mental-type enemies are notoriously difficult to deal with, and Grausam’s title fits that danger perfectly.
The fact that his fate is unclear only adds to his intrigue.
If the remaining Seven Sages are ever explored further, Grausam is the one most fans are eager to learn more about.
Other Important Demon Characters
Kvarl, the Corrupt Sage
(Fuhai no Kenrō Kvarl)
Kvarl brings the terror of demons out of legend and into the present.
As the creator of Zoltraak, he once forced humanity into sealing him away.
But times change.
Humans analyze Zoltraak, develop defensive magic, and turn what was once a demon’s ultimate weapon into a common spell.
Kvarl symbolizes demon supremacy—and its collapse through human research and inheritance of knowledge.
That Frieren lives long enough to witness this shift is what makes the victory so satisfying.
And it’s Fern who delivers the final blow.
The new generation defeats what was once humanity’s greatest nightmare.
Lügner
Lügner functions as Aura’s top operative and negotiator.
He’s cunning, observant, and skilled at manipulating human psychology.
His blood manipulation magic allows seamless offense and defense, and his mindset is closer to that of a disciplined warrior.
That seriousness earns him quiet popularity among fans.
Yet he also represents the limits of demon rationality.
He cannot comprehend humans suppressing their mana—a tactic that defies demon logic.
That blind spot leads to his defeat, making his end feel quintessentially Frieren.
Linie
Linie embodies the “cute but terrifying” archetype.
Her mimicry magic allows her to replicate not just techniques, but the flow of mana itself.
She copies Eisen-level movements to pressure Stark, but her body can’t keep up.
Mimicry has limits.
Stark endures—and ends the fight with a single decisive strike.
It’s a victory that feels distinctly warrior-like.
Draht
Draht is best described as a wannabe assassin.
His wire-based beheading attacks are deadly, especially against unprepared opponents.
But he’s impatient and prone to overconfidence.
Once he believes he’s won, he relaxes—and that’s fatal.
His swift defeat by Frieren reinforces a recurring lesson:
demons underestimate humans, and they die because of it.
Final Thoughts: Demons in Frieren
The demons of Frieren: Beyond Journey’s End are beings who:
- Speak human language, yet never truly communicate
- Appear emotional, yet are fundamentally different
- Are terrifying not just for their power, but for their alien values
Seen individually, each demon serves a narrative role:
Aura embodies arrogance, Kvarl represents the passage of time, Macht pushes the coexistence theme to its breaking point, and others highlight the limits of demon rationality.
Organizing demon characters by rank and role makes it far easier to understand who’s dangerous—and why—as the story moves forward.
Whether you’re analyzing the lore or just enjoying the series as a fan, this kind of overview becomes increasingly useful as Frieren continues.
