Even the soda bottle in his hand fell to the ground and shattered.

"Hey... what's wrong with that look on your face? Are you scared by what's happening outside?"

Yuu Aya frowned, completely baffled as to what Kakine Teitoku was doing.

"...I'm going out for a little while."

"Go out? Didn't you say you weren't interested in things outside—"

Followed by.

Under the watchful eyes of Yuuka Mimi, Kakine Teitoku's body underwent a very strange change in an instant.

A very unique aura surrounded him.

as well as--

Those eyes turned golden.

"I need to make an idea now."

Disappeared.

Without any warning, without even the slightest prelude, the number one Level 5 esper in Academy City simply vanished before his eyes.

…No.

From this moment forward, he will no longer be the number one figure in Academy City.

The true number one is someone else entirely.

As for Kakine Teitoku, he has completely rediscovered his true identity.

And all of my memories.

boom! ! !

Accelerator then raised his hand, instantly gathering immense power into a single force.

His pure gray wings trembled with his movements.

Even just the aftershocks generated by this are enough to shatter all of this world and all of this phase in an instant.

but.

"...Tsk."

The pair of gray wings were not entirely under his control.

Now, even if Accelerator wanted to do something with it, the wings only began to become faintly visible, and he was completely unable to unleash any further power.

"As expected, this thing cannot be fully mastered yet."

Pure gray, the wings of chaos.

The reason why the color is gray is because it is the color produced when black and white are mixed together.

Black represents "killing intent," and white represents "protection."

And, by fusing these two concepts together, an absolute power that transcends the concepts of strongest and infinite is born.

The power was so immense that the excess power gained from acquiring it instantly elevated the first person's ability to Level 6 (an absolute power user).

It's practically like a freebie.

Even the Demon Wings obtained after merging with that being called Q-Demon, or the Platinum Wings that were integrated into the overall consciousness of the Misaka Network, are far inferior to the ultimate power.

Of all the "wings" he ever used, this pair of gray wings was undoubtedly the most powerful force ever.

It is a power that can even defeat the being known as the Evil Eye.

But the greater the power, the more difficult it is to control.

The black wings represent the emotion of killing intent, while the white wings represent protection.

He still couldn't figure out what kind of feelings these pure gray wings represented.

If one cannot understand the essence of the matter, one will not be able to fully control such a tremendous power.

Even he, who possesses vector manipulation and the essential power to control the direction of all energy, is no exception.

As Accelerator moved, the wings behind him vanished.

The whole world seemed to return to calm in an instant, as if everything that had just happened was merely an illusion.

So, what should we do now?

The first person then turned around.

Before him, both the goddess who was a demon god and the demon named Kronzun were staring at him with incredulous eyes.

But Accelerator didn't focus his attention on them at all.

Instead, he slowly walked towards the direction of another person.

Standing not far from me was the white-haired, red-eyed girl with twin ponytails.

She had waited for him for far too long.

"…I."

seen.

When she finally saw the figure she had been longing for day and night appear before her, she could no longer control her emotions.

Tears streamed down her face.

"I'm not... I'm not dreaming... I'm absolutely not..."

"This is not a dream."

Tick.

Those fingers, even more slender than a young girl's, gently stroked her cheek.

The tears will follow.

"I'm sorry for making you bear so much all by yourself."

Accelerator spoke in the gentlest of tones.

"I'm sorry, but I'm back now."

"From now on, you will never have to worry about anything again, Hatsune Miku."

I'm back.

That one sentence alone shattered all the shackles in the girl's heart in an instant.

She could no longer control herself.

"Waaaaaah!!!"

She held Accelerator tightly with both hands.

Accelerator didn't say anything either.

He maintained a calm expression, letting the girl cry in his arms, without saying anything as he used to.

She simply let the other person vent their emotions.

"I've been waiting for you for so long. I always thought you wouldn't come back. Why did you leave me all alone..."

"I'm sorry, it's my fault."

"I hate you... I really hate you... You're the person I hate the most right now...!!"

"Even if you want to kill me, I won't have any complaints."

"I don't want to do that kind of thing... I... can't stand being without you anymore."

After a long while, the sobbing finally subsided.

She wiped away her tears and pulled away from his embrace.

"…this."

A faint white light flashed.

She then revealed the pair of wings on her back.

"I always keep your things with me."

These white wings can be said to be replicas of Accelerator's power.

Now, it's time to return it to him.

but--

"Keep it."

Upon his return, he responded to the other party with only these gentle words.

"This power is better suited to remain in your hands now than in mine."

"…Really?"

Hatsune Miku took a deep breath.

“I…did a lot of bad things while you were away.”

"I know everything."

"I can't stay here any longer, everyone... I've hurt them all!"

"Don't worry about that. I've already integrated the relationship between the previous timeline and this timeline. All the effects you had have disappeared."

"That's not what I meant...no, that's not it..."

Hatsune Miku shook her head.

A bitter smile appeared on the girl's face.

"Even if you erase what has been done, the history that has already been done will not disappear."

"...So, what do you plan to do?"

Accelerator looked at Hatsune Miku in front of him.

And she made her decision immediately.

"I want to do the same thing as you."

That's right.

Now, both Hatsune Miku and Accelerator share the same identity.

—A person burdened with sin.

"I'm going to make up for all of this."

The girl made up her mind and said what she was determined to do no matter what.

"I want to make up for my past mistakes, just like you are now. But simply regretting won't change anything."

The world is now facing a very critical situation.

"I must work even harder to stop these things from happening, so...!"

As Accelerator said this, he felt his hand being gently held.

"We must survive."

Hatsune Miku stared intently at him with a determined look.

"To live and fight to stop all of this, to atone for the mistakes we have made in the past... to protect more people from these calamities, we... must live well."

"And then, fight hard to resolve all of this!"

After a long time.

Hatsune Miku only felt someone gently stroking her forehead.

Accelerator.

He smiled softly, looking at himself with a somewhat gratified expression.
