Then, standing between darkness and emptiness, he seemed to sense something.

He stared straight at a spot that no character in the "work" could possibly notice.

"Is that right, don't you think?"

——————————————————————————————————

Aside from Accelerator and Hatsune Miku, what happened to the others?

Whether it was a world Accelerator had been to or one he hadn't, all the worlds connected to the World Transfer Station had completely vanished because of the previous battle.

The transit station, which was called the World's Transit Station, was completely shattered due to the energy explosion of this battle.

The people and things in those worlds were swallowed up by that mysterious, extremely colorful light and vanished into absolute darkness, with nothing able to survive.

This is the true, overwhelming despair.

however.

Amidst this chaotic and terrifying despair, a final glimmer of hope has been preserved.

wow-

In the darkness, two humans slowly rose from the ground.

"...Where am I?"

"Who knows."

Hatsune Miku looked around in utter shock.

Faced with Hatsune Miku's question at this moment, Accelerator could only frown.

"It's probably what the whole world would look like after it's been destroyed."

They now find themselves in a world where science and magic intertwine.

At least that's how it used to be.

However, after the devastating blow, all living beings and phases in this world, as well as the demons who could rewrite everything at will, completely disappeared from this world.

No, in the end, even the concept of the world has disappeared.

The boundaries between heaven and earth disappeared, and then darkness spread in all directions.

Even if you can still feel the ground beneath your feet and breathe in the oxygen you need to survive, no one, regardless of who they are, could continue to live in such a place.

Unless, of course, they are incredible beings like Accelerator and Hatsune Miku.

"Yifang, look!"

At that moment, Hatsune Miku suddenly realized something.

"Look there...!"

The girl pointed to the sky, and the two saw that an incredibly strange thing had already appeared there.

That was something completely out of place in this darkness.

It was a completely dark void.

Although it sounds strange, the appearance of a pitch-black hole in a dark space, even though both should be black, still creates an unnatural protrusion.

It evokes the imagery of a dimension that suddenly emerges from a two-dimensional space, a dimension that transcends the concept of quantity.

Not to mention Accelerator, who had a deep memory of that place, even Hatsune Miku knew that it was the place they were going to.

The girl straightened up, and unconsciously felt her legs trembling slightly.

That's because of the instinct transmitted by the body, a fear of something even more terrifying.

But—she overcame this weakness through her own willpower.

"...We can definitely survive and bring everyone back, right?"

The idea that victory would bring back all the vanished people and the world was instilled in the two of them at some point, probably after they met the young man named Yunze.

Although they didn't know the details of what happened with that young man, Accelerator and Hatsune Miku knew that they had to win no matter what.

Even if it's just the two of them.

"Hatsune."

"I'm fine."

Before Accelerator could say anything, Hatsune Miku spoke first.

She looked at the first person with a serious and earnest gaze.

"I am no longer the person I used to be. I will overcome my cowardice and use all my strength to play my part...!"

"...Hmph, I never intended for you not to come with me, did I?"

The first one smiled, which was rare for him. Then, he raised his hand and summoned the dark black generator.

In fact, the first one harbored a pain that no one could imagine.

The girl who was his pillar of support—Last Order—was also devoured by the other party.

But he knows.

If we try hard enough, we can definitely save them.

That is precisely why he has every reason to fight.

Using the power of space, the two of them entered the interior of that thing directly.

Om-! !

After a déjà vu feeling as if they had been sucked into a wormhole, the enemy's main camp was revealed before them.

wow-

Then, a sensation as if entering some kind of liquid instantly came over me.

“Wu——?!”

Upon experiencing this sensation, Hatsune Miku felt a little nauseous, but quickly overcame that urge.

Both of their feet touched the ground.

…No, it was less the ground and more something that could support their weight.

Because what they were stepping on was something very soft, still wriggling, like the internal structure of a living organism.

"This...this place?"

Hatsune Miku looked around in shock.

They were in a tunnel-like location.

It was completely different from the black hole-like space they had entered, but this was indeed the enemy's headquarters.

"Could it be inside some kind of creature?"

"It's not hard to imagine, actually."

After observing for a while, Accelerator came to a certain conclusion.

"If the 'Evil Eye' is someone's eye, then this is probably another part of that person's body."

"Ugh...it feels so disgusting..."

"They have such great power but they can't even spare a decent arena. Ha, what a twisted way to play. That eyeball bastard."

Accelerator turned his gaze forward and began to observe.

First of all, he was not observing purely the outward appearance of things.

Rather, it is the flow of energy along specific directions that only he can detect.

"...How is it?"

"There's no mistake, it's the same type of energy I felt when I came here before."

After drawing a simple conclusion, the first person nodded.

"From now on, every step must be taken with utmost caution."

"…I see."

There were no extra words, no unnecessary greetings.

The two of them made every effort to prepare for each other, and no longer treated this place with any negligence.

then.

The moment one side moves forward, it takes its first step.

A tremendous change has taken place in the world.

"—This, this is!"

Hatsune Miku didn't hesitate and instantly changed her outfit to Snow Miku 2019.

However, one side of the passage remained inactive.

It was precisely because he clearly saw the direction of the spatial flow that he knew that this spatial change was not harmful to them.

That was merely a matter of moving them to a much larger location.

Clang!

Under a dark red sky, what appeared before the two was a world that resembled the end of the world.

Everywhere you can see the scenes of things from different worlds being destroyed and piled up together.

Snap, snap.

From that ethereal environment, one could hear clapping coming from afar.

"It's amazing that you guys survived such a devastating attack!"

A person appeared before them.

With her appearance, the previously lifeless space was instantly covered by a fantastical hue.

It's an extremely purple atmosphere.

As that light enveloped the world, things appeared all around, falling like raindrops.

Butterfly.

Pink, and pure purple.

Rather than butterflies, they are light butterflies formed from some kind of particles. These light butterflies gather and swirl in the deepest part of the purple atmosphere, eventually forming a human-shaped posture.

A petite and shapely young woman.

She wore a purple dress, her face was covered with some kind of light purple veil, and she had long purple hair that reached her waist.

"That's amazing, absolutely amazing."

"…Who are you!"

Hatsune Miku raised her wand, immediately gathering a large amount of magical power in advance.

The magical transformation of the ice and snow structure into a massive deep blue aura dispersed the opposing purple atmosphere.

"Oh? I didn't expect that. Not long ago, she was just a little burden, but now she has evolved her power to this extent?"

Even after witnessing Hatsune Miku's aura, the purple-haired girl maintained her elegant demeanor.

butterfly.

A mysterious girl, whose true identity is unknown, whose reason for being here, and why she is doing this, appeared before the two of them.

"Where are your accomplices?"

Accelerator looked around but didn't see anyone else.

"You were sent here alone, are you planning to abandon me?"

"That's so mean! Saying that makes it sound like I'm about to die."

"Why, don't you know?"

After hearing her words, the first person couldn't help but laugh.
