The power to manipulate star particles had originally belonged to the Star King Dragon, Veldanava.
And as his daughter, Milim had inherited that power perfectly.
What kind of existence was Veldanava?
He was the supreme god of this world.
It went without saying how terrifying the strength of such power must be.
When Milim had used this same technique against others before, there had only been one person capable of resisting it.
Guy Crimson.
Even then, the reason Guy could stand against Milim was not because his magicule reserves were comparable to her seemingly limitless power.
It was because of his Ultimate Skill.
"Prideful King."
Yes, the Sin-type ability possessed by Guy was also called Prideful King.
However, the power it granted was completely different from the one Ren wielded.
Guy's version of Prideful King allowed him to replicate degraded versions of other Sin-series abilities.
In simpler terms, it was essentially a low-spec imitation of the Star Creation Map: Avesta.
Without that ability, even someone like Guy would not dare claim he could truly contend with Milim.
She was the beloved child of the world itself.
From the moment she was born, she possessed a quantity of magicules that no one else could even begin to approach.
And on top of that, she had the bug-like skill "Wrathful King," which could raise her strength without limit.
If you ignored the drawback of eventually losing her sanity…
Then Milim was essentially invincible.
The moment Ren's Cosmic Slash collided with Milim's pillar of star-particle light, the entire space around them began to tremble violently.
Cracks appeared throughout the sky like fractures spreading across glass.
Then the space itself began to chip and fall apart.
It was obvious that the attacks unleashed by Ren and Milim had already exceeded the tolerance limit of the surrounding dimension.
If things continued like this, the space itself would collapse long before the two of them could decide a winner.
"Hey, Guy… if we keep standing here, we're going to be in serious danger too, you know?"
The Demon Lord Dino, who had previously looked half-asleep the entire time, was now completely awake as he felt the terrifying waves of energy rippling through the air.
"Do something already!"
"If I'd known this Demon Lord banquet would be this dangerous, I never would've come to watch the show."
The other Demon Lords didn't look much better than Dino.
The battle between Ren and Milim had clearly gone far beyond anything they had expected.
Even Demon Lords weren't immune.
If they were caught in the shockwaves of this battle, their lives could still be at risk.
For the Awakened Demon Lords, it might be manageable.
But for figures like Frey and Carrion, who had not awakened yet—or Ramiris, whose power was already depleted—
Even the residual aftershocks of the battle could be fatal.
"I'm already reinforcing the barrier as much as possible," Guy said, his tone losing the relaxed amusement he had earlier.
His fingers flicked rapidly through the air, constructing new layers of magical defenses.
"If any of you specialize in this kind of thing, get over here and help."
"Otherwise this space won't hold."
Behind him, the two maids standing quietly until now suddenly released enormous waves of magicules.
They were the Demon Dukes known as the Primordial Blue and Primordial Green.
Their power easily surpassed that of most Demon Lords.
Now they were assisting Guy in stabilizing the dimension.
Earlier, the location Guy had transferred everyone to was actually one of his territories within the Demon Realm.
He had assumed the environment would be a better place for Ren and Milim to fight freely.
But clearly…
He had underestimated Ren.
He had never imagined the battle would escalate to this level.
If the two of them continued fighting without restraint, then forget about his territory—
The entire Demon Realm itself might sink into destruction.
Meanwhile, the battle between Rimuru and Luminous had already ended.
The two of them had apparently reached some kind of private agreement.
Now they both stood watching the crumbling space around them with headaches.
Rimuru sighed heavily.
He genuinely hadn't expected things to escalate like this.
The entire reason for this gathering had originally been to deal with someone as insignificant as Clayman.
Yet somehow the situation had spiraled into a battle that threatened to tear apart reality itself.
Before coming here, Rimuru had always believed that compared to Milim, Ren was the rational one.
In fact, Ren had even repeatedly reminded him to behave himself.
And yet now…
Rimuru had behaved exactly as instructed.
But the person who had warned him was currently causing more chaos than anyone else.
In order to prevent the situation from spiraling into something completely uncontrollable, Rimuru quickly took action.
First, he used the power of "Covenant King" to summon the Storm Dragon Veldora.
Then he hurried over to help Guy reinforce the unstable space.
At the same time, two figures who had arrived as Ren's companions also stepped forward.
Wiz and Medea.
At that moment, both of them released an amount of magicules comparable to that of the Primordial Blue and Primordial Green.
They immediately joined the effort to stabilize the collapsing dimension.
Wiz was a lich.
In her own world, she had once been one of the most brilliant archmages alive.
Complex magical formations and barrier spells were practically second nature to her.
As for Medea—
There was no need to explain.
She was the greatest magus of the Age of Gods.
If one ignored pure magicule output and judged solely by knowledge and mastery of magical theory, then every Demon Lord present would probably look like amateurs in comparison.
With the assistance of Wiz, Medea, and Rimuru, the unstable dimension was finally reinforced just before it could completely collapse.
Guy glanced at the three of them and gave a small nod of appreciation.
If the space had shattered earlier, whether the Demon Lords themselves would have been injured was another matter.
But if the Demon Realm had been destroyed as a result…
Then he—the Primordial Red, Guy Crimson—would have been remembered as the greatest sinner responsible for its destruction.
Guy then turned his attention toward Wiz and Medea.
"I didn't expect that mere attendants would possess strength like this."
"If I had realized earlier…"
He sighed slightly.
"…I probably wouldn't have encouraged your master to fight Milim."
Looking at the two women before him, Guy's expression showed genuine surprise.
It wasn't just that their magicule reserves rivaled those of the Demon Dukes behind him.
The role they had played in stabilizing the space and reinforcing the barriers had been absolutely crucial.
To put it bluntly—
Without their help, there was no way the dimension could have held together just now.
Not only were their magicules powerful…
Their understanding of magic itself was on an entirely different level from the Demon Lords, who usually relied on brute strength in battle.
However, Wiz quickly shook her head.
"Ren isn't our master or anything like that."
"If we had to put it into words…"
She smiled slightly.
"We're just really good friends."
"Well… although it's true that he does have quite a few subordinates."
"And among them, there are several people who are about as strong as we are—maybe even stronger."
Unlike the others, Wiz and Medea never used honorifics like "Lord Ren."
To Wiz, Ren truly was just a friend, not someone she served.
As for Medea…
That situation was even more complicated.
If she wasn't completely fascinated by Ren's body and constantly dreaming of marrying him, there was no way she—Medea the Witch—would casually form a contract with someone.
As for calling Ren her "master"?
That was even more ridiculous.
Back in the world they originally came from, she had been the Master.
Ren had been her Servant.
So when exactly had the tables turned and Ren suddenly become the one in charge?
