"Who do you think I am?"

"Is that so? That's good then."

Or is it the same tone as always?

Yoshikawa smiled, and then said nothing more.

"…that."

Beside him, a petite figure clung tightly to the hem of Yifang Tongxing's clothes.

"Really, will you be back soon?" Misaka asked you with great concern.

"Ah, that's right... that's exactly it."

The first person nodded, responding to the girl with great seriousness and earnestness.

This girl was his psychological pillar and the most important person to him.

"I made a promise to you, I will definitely come back as soon as possible."

Everyone, including the extra characters, nodded in response.

then.

Only after confirming that everything was arranged properly could the first person truly feel at ease.

"Ready to go."

He grabbed Hatsune Miku's arm, manipulated the spatial vectors, and disappeared into this space together with her.

then.

"...Really, is everything alright?"

Upon arriving in the outside world, the girl beside him asked with a hint of worry in her voice.

"Can we really end everything perfectly and come back here unscathed?"

Accelerator stood beside her, pausing for a moment.

"of course."

However, he immediately followed up with his reply.

"Whether it's you and me, or those other guys."

“We…we absolutely have to come back to this place; there is no other possibility.”

correct.

Although this city holds incredibly ugly memories for him.

Perhaps even now, Accelerator still cannot accept the corrupt and dark side and interior of this city.

Even so—

Within this city, there are still people he needs to protect, care about, and love.

That's why Accelerator will definitely return to this city.

This is because it is the "Academy City" in his memory.

"So, are we getting ready to leave?"

"Not that early."

Nevertheless, he did not intend for the two of them to simply leave this world.

He needs to bring other people with him.

"Even if I don't want that guy to get involved, there's no time to make any other choices at this point... Damn, this is really difficult."

"Eh? Should we... should we bring someone along?"

Hatsune Miku looked at him with a puzzled expression, but Accelerator did not respond with words.

He then looked up at the streets in the distance of the Seventh School District.

"I'll handle the work that required that guy to come along."

"Or rather, no matter what, I should be the one doing this kind of thing..."

————————————————————————————————————

"So... are you planning to leave?"

Kamijou Touma stood outside his apartment, looking at the two people in front of him.

"According to the latest news, the intruder who attacked District 23 has been eliminated, and it seems even their remains haven't been found..."

"In that case, it should be considered our job even more."

The water behind responded in a reasonable tone.

“That thing came from England and ended up in Japan. It’s our responsibility that we couldn’t stop it. Now that things have come to this, I will not let it end so easily.”

“Since the chief bishop of the Anglican Church has issued such an order, we must complete it, even if it is just to finish it.”

Both the Water of the Rear and the Fire of Kanzaki took the tasks assigned to them by their superiors extremely seriously.

Even though they themselves weren't sure whether the mysterious entity that attacked them had truly been eliminated, they still went anyway.

"I see... Well, I understand now."

Touma Kamijou nodded, respecting the decision the two had made.

"Take care of yourselves, and absolutely do not push yourselves."

"...Hmph, you're still the same as always."

After hearing Touma Kamijou's words, even Mizuki, who had always spoken with a straight face, couldn't help but smile.

"But that's precisely why you were able to stop me back then."

"Ah... So you all have to promise me that no matter what happens in the future, you won't do anything reckless again."

Now, both Kanzaki Kaori and Kanzaki Kaori laughed at the same time.

Do you think this spiky-haired high school student has the right to lecture them about such reckless behavior?

The saints said nothing more.

In the blink of an eye, their figures completely disappeared in front of the door.

Kamijou Touma stood at the doorway, observing for a long time.

"You should be able to come out now, right?"

Click.

From behind, the sound of the toilet door being opened came from behind.

Touma Kamijou turned around, and just as he had guessed, someone appeared in his room.

Moreover, it was someone he was absolutely familiar with, someone he knew very well.

"That's quite rare, you actually came to find me."

White hair, red eyes.

His entire body was filled with an ominous aura, making him seem like a monster.

Even so, he can still be considered a "human being".

"There's no time to explain the details right now."

"I knew it! Usually, when someone like you comes to me, it's never anything good."

Touma Kamijou looked around the room. Index wasn't there; she had just come downstairs with her calico cat to buy a drink from the vending machine.

Incidentally, the shrunken Othinus was also taken away because the calico cat was holding it.

"Before that, can I do something for you?"

"What do you want to do?"

Accelerator looked at the boy in front of him, but—

"It's nothing, I just wanted to leave them a note."

Touma Kamijou smiled and walked straight into the room.

"If I just leave without saying goodbye, when I come back, Index will definitely bite my head a few times without any mercy, right?"

"...You bastard."

Even without saying it, Touma Kamijou must have sensed the seriousness of the situation to some extent.

Even so, he was still able to maintain that smiling expression, and even felt that he would definitely come back.

Even Accelerator should have been prepared for the worst.

For a teenager, such behavior cannot be considered as putting on a brave face.

"I have to come back."

After writing the notes for Index and Othinus, the boy stuck them on the refrigerator and left the room.

His face bore an expression of unwavering determination.

"It is precisely because of the seriousness of the matter that I need to be even more prepared."

"I will definitely come back... No matter what, I will return to Index and the others, safe and sound, with the best and most wonderful outcome!"

Really... he hasn't changed at all, this guy.

No matter how many times Accelerator travels to different worlds, no matter how many different worlds he has seen.

The man before me will never change his true nature.

"...Let's get ready to leave."

There's no need to say anything more.

After taking Touma Kamijou downstairs, Hatsune Miku was waiting for him there.

then.

The three of them traveled together, heading towards the transit point of that world.

"In order to restore this world to its original state, let's prepare to do what we can...!"

Chapter 818 Battle at the End of the World

Accelerator, Hatsune Miku, Touma Kamijou.

These three are the people who have been decided to participate in this performance.

Then, those who arrived after them were beings whose strength was comparable to theirs, or even surpassed it.

"You guys are really slow."

A massive spatial rift.

Then, standing directly in front of the crack were three people.

After they saw Accelerator and his two companions arrive, they called out as if urging them on.

"Looks like everyone's gathered. Let's hurry up and deal with these damn things and come back as soon as possible."

Kakine Teitoku, Right Fire, and Orelus.

"Huh? Why are you all here too? And there's even the Right Flame here..."

"Since we are facing a battlefield on a global scale, it is impossible for me not to be involved."

After revealing an unhappy expression as if she had been looked down upon, Right Fire looked at Kamijou Touma.

"However, it doesn't matter if you have any prejudice against me."

"No, I wasn't talking about that..."

Kamijou Touma responded to him with a hint of helplessness.

Upon seeing this scene, Kakine Teitoku couldn't help but walk towards Accelerator.

And they directly questioned him.
