In the world of Frieren: Beyond Journey’s End, the Demon King is often portrayed as an enigma of absolute malice. However, as the series progresses, we learn that demons are not merely monsters—they are biological machines of logic and evolution. This raises a massive question: Why would the Demon King issue a specific, resource-heavy command to “Kill all elves”?
The answer isn’t just hatred. It’s fear. Specifically, a fear rooted in the precognition of Schlacht the Omniscient.

The Power of 1,000-Year Foresight
To understand the genocide of the elves, we have to look at the Demon King’s right hand: Schlacht the Omniscient.
Schlacht possessed the ability to see one thousand years into the future. In the demon hierarchy, where magic is everything, this isn’t just a parlor trick; it is the ultimate tactical advantage. However, foresight in Frieren is often depicted as a burden of inevitability.
If Schlacht looked forward 1,000 years from the height of the Demon King’s era, he wouldn’t have seen a world of demonic utopia. He would have seen a very specific, white-haired elf standing over the Demon King’s throne, wielding mana so refined it eclipsed the “Sages of Destruction.”
The Timeline Fits: The 1,000-Year Gap
The timeline is the smoking gun here.
- The Command: Centuries ago, the Demon King ordered the total annihilation of the elven race. This led to the near-total disappearance of elves from the continent.
- The Result: By the time Frieren joins Himmel’s party, she is a “rare” relic of a bygone era.
- The Prediction: If Schlacht saw 1,000 years ahead, his vision would land exactly on the decade where Frieren, Fern, and Stark (or perhaps the original Hero Party) dismantled the Demon King’s empire.
By ordering the death of all elves, the Demon King wasn’t being cruel for the sake of it. He was attempting to prune the timeline. He was trying to delete the one variable—the elven mage—that his foresight identified as the catalyst for his own demise.
The “Frieren Problem”: Why Elves are a Demon’s Nightmare
Why were elves specifically targeted instead of humans? Humans are short-lived; they are “problems” that solve themselves within 70-80 years. Elves, however, are the only race capable of matching a demon’s greatest strength: Time.
- Mana Cultivation: Demons spend hundreds of years honing a single spell. A human mage can never truly match a demon’s mana pool through natural means.
- The Immortal Counter: An elf like Frieren can spend 1,000 years doing nothing but practicing the “boring” basics of mana concealment and detection.
Schlacht likely saw Frieren throwing high-level magic—spells perfected over a millennium—against the Demon King. He realized that as long as elves existed, the demons’ monopoly on “time-based power” was under threat. The command “Kill all elves” was a pre-emptive strike against a weapon that hadn’t even finished being forged yet.
The Irony of Fate: Making the Hero
In his attempt to prevent his death, the Demon King actually ensured it. This is a classic “Causal Loop” or “Predestination Paradox.”
By destroying Frieren’s village and killing her people, the Demon King created the very monster he feared. He turned a solitary elf into a survivor with a grudge, who was then picked up by Flamme and taught the specific art of “demon-killing” through mana deception. If the Demon King had left the elves alone, Frieren might have spent the last 1,000 years peacefully collecting useless spells in a forest, never lifting a staff against him.
Key takeaway for the journey: The goal was survival, but the process—the genocide—was the very thing that fueled the fire of the Hero Party. The journey to the goal is where the Demon King lost.
Proof in the Narrative: The Battle with Macht and Solitär
Recent chapters and arcs involving the “Sages of Destruction” show that even the most powerful demons are baffled by Frieren’s existence. Solitär, an incredibly ancient and scholarly demon, notes that Frieren’s magic is “unnatural” for the current era.
This confirms that Frieren is an anomaly. Schlacht’s foresight would have flagged this anomaly immediately. If you saw a nuke being built 1,000 years in advance, you would try to destroy the uranium mines today. For the Demon King, the elves were the “uranium.”
Conclusion
The command to “Kill all elves” was not a random act of villainy. It was a strategic, failed attempt by a King and his Seer to outrun destiny. Schlacht saw the future, and in that future, an elf was the end of all things. By trying to kill the future, they created the very Legend that would eventually walk through the Demon King’s castle gates.
