"Hahahaha, all of you, die—!!"

boom--! ! !

The attack, which exhausted the highest limits of both Die and Yi's souls, struck their opponent mercilessly.

Even if the Demon God were to face this attack head-on, it would be difficult for him to completely block it.

however.

The young man didn't even move.

"Varied--?!"

"This is impossible! You...you who are you?!"

The young man stared coldly at the two people in front of him, and merely blinked.

For an instant.

Yi and Die's bodies belong to two different people.

"Since you loathe your lives so much, then just go with the flow and bring forward your fate to the moment of 'destruction.'"

They all vanished forever from the script of the story.

“…Huh?”

"What happened? What happened?"

Whether it was Weite, Advisari, or even the Demon God and the vampire girl, they all couldn't help but show a moment of astonishment.

"I remember, it seems like I was fighting someone here just now?"

"His injuries have healed."

"Oh... thank you, um... wait, wait—who are you?!"

Witte and Advisari looked at each other, but he only glanced calmly at Takibayashi lying on the ground.

That alone was enough to heal his injuries.

"Is that… done?"

Then the young man turned away.

The Demon God stared at him, looking at him in disbelief.

"Who exactly are you...?"

"...I don't have any special identity, I'm just a passerby watching the show."

Subsequently.

The young man waved his hand and disappeared from the spot.

"Just call me Yunze, but... you probably won't remember me anyway."

that's it.

This final battle has now come to a complete end.

Chapter 839 Don't think it's over yet!

"drink--!!"

With a sharp, piercing sound, the blade tore everything apart.

Kanzaki Kaori used her superb skills to cut her enemy in two with a single stroke.

Under the power of the single-handed slash that could even sever the angels of a monotheistic religion, countless enemies turned to ashes... and never to be reborn.

"Huh? That's strange..."

"What's wrong?"

Meanwhile, Mizuki, who was also fighting nearby, noticed Kanzaki's unusual behavior and couldn't help but move closer to her.

"What happened?"

"...If it were before..."

Looking at the monsters around her, Kanzaki couldn't help but show a somewhat incredulous expression.

"These monsters, if it were before, would have come back to life even after being killed, right?"

"Indeed, that seems to be the case."

The other people fighting nearby also noticed this.

Followed by.

"…Um?!"

Under everyone's watchful eyes, something strange happened.

I saw.

All the alien monsters in front of them vanished one after another after what seemed like a roar.

They didn't even need to lift a finger.

Like dust, these monsters disappeared at a visible speed, and that's not all.

Globally… no, in all worlds, all monsters of the same type meet the same fate.

"What...what is going on?!"

This situation immediately stunned all the knights from London.

Kanzaki, the water behind, and the knight commander and the second princess who arrived not far away were also like that.

"What exactly happened? Just now, those monsters were causing quite a ruckus!"

"We...we have absolutely no idea either."

No matter who you ask, you won't get a reasonable answer.

Kanzaki remained silent, gazing at the sky, where the monsters that had been falling before were no longer descending.

and.

…There was a vague feeling that made her think that the world seemed to have changed a little.

It's like——

"The power that belongs to this world... seems to have changed?"

"what are you saying?"

His unintentional murmur prompted Shui, who was standing behind him, to ask him a question.

"No, it's nothing."

Kanzaki Kaori shook her head and put away her Seven Days Seven Swords.

However, regardless of the circumstances.

In terms of results.

The world has finally returned to its former peace.

————————————————————————————————————

everything is over.

After ending all of this himself, Accelerator went directly to the location of the place that had served as a transit point for the world.

Clearly, after a devastating bombing like the one before, this place no longer serves as a world transit point.

The soul system has also disappeared, and everything related to it will cease to exist.

From this point on, all traces left by those transmigrators with soul systems in various worlds will disappear.

This applies to Accelerator and Hatsune Miku as well.

…That's right.

If we do nothing and just let things take their course...

"...If only there were something that could reconnect all the worlds together."

The primordial sea that created these worlds has disappeared.

Therefore, if we want countless worlds and worldviews to settle down, we need a substitute for the thing that was created.

Where can one find something that can support the weight of the entire world and remain in this state forever?

Very simple.

The person who can do that is right here.

boom--! ! !

Without the slightest hesitation, the first person unleashed their full power.

Those enormous wings that shimmered with black, white, and gray hues.

Now, it is spreading to all parts of the world.

This has nothing to do with speed alone. The moment those wings burst forth, the entire world, every place, even every corner, was imbued with the aura of those wings.

Clearly, since the primordial sea is the origin of all things, there cannot be anything that can compare to its size.

In that case.

Therefore, Accelerator, who cleared away that primordial sea, is undoubtedly the most suitable to bear this burden.

And the choice he made was also reasonable.

Accelerator began to recall everything he had done so far.

First of all.

What is the first thing you do after experiencing brain damage?

"If I could connect with so many people."

It is connected to the Misaka Network, a network formed by the giant clone brains.

But that wasn't the end. After that, the first person gained the approval of the Misaka Network's overall consciousness and thus received the support of the entire Misaka Network's massive computing power, which can be considered another new connection.

After connecting with the demon girl named Qliphoth545 and achieving a two-in-one state, what he gained was a further sublimation of the Black Wings, namely the pair of demon wings.

By connecting with the demon girl and Misaka's network computing abilities at full power, they obtained a third tree independent of the world—and platinum-gold wings that could plant such things within the world.

Upon closer reflection, there are many people who could connect with the first one.

This is not simply addition, subtraction, multiplication, or division. After connection, it can gain immense power. This has nothing to do with the strength of the connected objects, but rather with the degree of matching of their properties at the time of connection.

This is something only someone like Accelerator, the number one in Academy City, could do.

Now, what he has to do is also very simple.

Having already possessed this pair, enough to defeat the Primal Massive Strength of the Pure Gray Chaos Wings.

What he needs to do is connect with all the world and worldviews before him.

bang——

A silent explosion echoed through various worlds.

Then, the wings, like data transmission belts, spread out in all directions and extended further into all worlds.

The number of worlds beyond the concept of infinity is fully integrated into the First Mind.

However, he did not simply want to possess everything in the world.

Instead, he uses himself as a vehicle to build a massive framework that can completely connect all worlds and prevent everything from becoming fragmented.

It's like a giant server, or a tree whose branches extend to countless worlds.

Such terrifying data is simply unacceptable to any being in this world.

"I can do it."

Only the number one in Academy City could say such a thing so easily.

"Only I can do this kind of thing, it's that simple."
