Four Knights of the Apocalypse Chapter 255 spoilers have arrived, and “Tragedy in the Demon Realm” shows just how dangerous Chaos Lancelot has become.
Lancelot is still resisting Cath from inside his own body, but the warning he gives the demons makes the situation painfully clear: get as far away from him as possible.
The Demon Realm listens.
Then it starts releasing monsters.
Four Knights of the Apocalypse Chapter 255 Spoilers and Full Summary
Chapter 255 begins with the demons recognizing Lancelot as one of the Four Knights of the Apocalypse and questioning why one of the heroes who saved their realm two years earlier has suddenly returned.
They quickly notice something much worse.
Lancelot is radiating an enormous amount of murderous intent.
When confronted, Lancelot struggles to speak and gives them a simple warning:
Run away from me.
At first, the demons don’t understand the seriousness of the situation. One even jokes about playing tag and suggests they might bring Lancelot before their king.
Lancelot responds by screaming for them to run.
That gets the message across.
Lancelot is Still Fighting Cath
The warning is another sign that the real Lancelot has not surrendered control completely.
He knows what his body is capable of doing and is actively trying to keep innocent people out of its path.
Cath is well aware of the resistance.
Inside their shared consciousness, Cath remarks that Lancelot is trying desperately to oppose him but believes he will eventually run out of options.
Cath is willing to wait.
For now, he seems content to enjoy whatever destruction comes next.
Why is Tristan Trapped?
Tristan remains confined while the crisis unfolds.
When he asks to be released so he can see what is happening outside, he is refused.
The reason is protection.
A human exposed directly to the Demon Realm’s miasma could suffer serious consequences, and Lancelot deliberately chose the Demon Realm rather than risk unleashing his destructive power in Britannia or the Fairy Realm.
That makes his decision strangely calculated.
Even while losing control, Lancelot appears to have chosen the place where he believes the collateral damage will be easiest to contain.
Unfortunately, the people actually living there might disagree with that assessment.
Zeldris Orders the Demon Realm Evacuated
The situation quickly becomes a full emergency.
Demons throughout the realm are ordered to evacuate to the Abyss, the prison where Gowther of Selflessness was once held for 500 years.
The order causes immediate panic.
Some demons question whether entering the Abyss means they will ever be able to leave again, but the command comes directly from the Demon King.
The implication is obvious.
Zeldris believes remaining outside is even more dangerous.
The Demon Realm Releases the Induras
The Demon Realm’s defenses escalate further when an order is given to release the Induras.
One identified as the Time Indura is sent out first, while another associated with Resentment is prepared as a possible follow-up.
The Time Indura does not last long.
Lancelot unleashes Death Penetration, followed by Shining Road, and the defenders soon report that the Time Indura has gone silent.
Whatever hopes the Demon Realm had of slowing him down with one of its most dangerous creatures disappear almost immediately.
The reaction says everything:
He’s too strong.
Zeldris Confronts Chaos Lancelot
The final pages bring Zeldris directly into the crisis.
He recognizes Lancelot as the friend of both Percival and Tristan and demands to know why he is doing this.
Lancelot does not provide an easy answer.
Considering what Chapter 255 has already shown, there may not be one he can give.
The chapter ends by setting up the next confrontation:
Chaos Lancelot versus Zeldris.
That leaves the Demon King standing between Lancelot and a realm that is already preparing for the possibility that it might not survive him.
Is Lancelot Still in Control?
Not completely, but Chapter 255 provides another strong sign that he is still present.
His warning to the demons matters.
Lancelot understands that Cath is using his body as a weapon, and he is doing what little he can to limit the destruction before his resistance fails.
That also explains why he brought the threat to the Demon Realm rather than Britannia or the Fairy Realm.
It doesn’t make the decision harmless.
It does suggest there is still a method buried somewhere inside the chaos.
What Happened in Four Knights Chapter 254?
Chapter 254 revealed that Lancelot remains conscious inside his transformed body alongside Cath and the Lady of the Lake.
He continues resisting Cath internally, but that struggle has not stopped his body from carrying out its destructive mission.
Chaos Lancelot eventually opened a path into the Demon Realm, where Zeldris and Gelda immediately sensed the enormous power approaching them.
Chapter 254 ended with Lancelot entering the realm and preparing his next attack.
Chapter 255 shows everyone else realizing just how bad that arrival really is.

What is Four Knights Chapter 256 About?
The closing teaser points directly toward the fight Chapter 255 spends its final pages arranging:
Chaos Lancelot versus Zeldris.
Zeldris has already watched one of the Demon Realm’s heavy hitters get erased almost immediately, while Lancelot is still struggling against Cath from within.
That gives Chapter 256 two fights at once.
Zeldris has to stop Lancelot from the outside.
Lancelot has to stop himself from the inside.
Neither job is looking particularly pleasant.
