"Since you don't plan to go, there's nothing I can do."

Accelerator put his hands in his pockets and prepared to leave.

"Oh dear, is this really a good idea?"

"It doesn't matter, what that guy said was nothing but some boring and stupid stuff."

Kakine Teitoku waved his hand dismissively, looking rather bored.

However, out of curiosity, he still took out his phone from his pocket and looked at the contents of the email he had sent.

The moment I saw the email message.

Boom! ! !

Accelerator heard a sound behind him that sounded like something being smashed.

"…oh?"

The first one turned around.

Under the astonished gaze of Yuuka Mimi, Kakine Teitoku threw the game controller away.

He even stomped the table to pieces with one foot.

"...Are you sure it's true, right?"

Why would I need to lie to you, kid?

"That's good."

The expression on the second person's face changed completely.

He went from feeling lazy to having a gloomy expression on his face.

His entire body emanated an aura of terrifying danger.

Even if you don't want me to go now, I will still go with you.

pat.

Stepping over the dust and fragments scattered on the table, Kakine Teitoku left the room.

He ignored the bewildered look on Yuu Aya's face.

"Wait... what exactly happened?"

"It's nothing, just a personal grudge."

Accelerator couldn't help but smirk.

"It's just some grudge that's been buried in that guy's heart for a long time."

——————————————————————————————

correct.

The place they stole together with Kakine Teitoku, Hatsune Miku, Takibayashi, Alice, Marisa, and Reimu Hakurei...

"This building... has no doors or windows."

A building without doors or windows.

Located in the 7th school district of Academy City, it was once a mysterious location that became part of urban legends.

That was the place Accelerator was told to come to in the mysterious email he received.

That is why Kakine Teitoku chose to come here with him immediately.

Inside this building lives someone he had always wanted to see in person, no matter what.

"Oh dear? So everyone's gathered here."

After circling around once, the others followed.

Those people were the group of girls who had come from Gensokyo.

"Ah~ Your city isn't very big at all."

The people walking at the front were the vampires from the Scarlet Devil Mansion.

Remilia Scarlett.

Despite her petite stature, the young girl displayed an expression that suggested she was quite mature and arrogant. Anyone familiar with her would immediately recognize her true nature.

After touring the Academy City, Remilia flew directly to Accelerator's side.

"You call this Academy City, right? Hmph~ It's not even as big as my Scarlet Devil Mansion, nothing special!"

"That's right, Miss."

—This is Izayoi Sakuya, who knows Remilia is talking nonsense, but in order not to hurt her self-esteem, she has to say nice things to her as much as possible, like coaxing a child.

"This is just a small city; it's nowhere near the size of the Scarlet Devil Mansion's interior. The entire city is only about the size of Lady Patchouli's library, no, even smaller..."

"Hahaha!! That's right, Sakuya has excellent taste! Hurry up and let this vampire lord see who the lord of this city is. I will teach him a lesson on how to become a qualified lord!"

…Of course, even Kakine Teitoku saw all of this as a scene of coaxing a child.

"However... speaking of this world itself, there are some things that really concern me."

This is an analysis that only Patchouli, a mage, could offer.

The girl held the book close to her chest and touched her chin with one hand, drawing a more detailed conclusion.

“I can feel a tremendous magical aura everywhere in this world. Hmm… although it feels different from the magic in our world, I can still sense it.”

"As expected of Patchouli! So, besides these, did you discover anything else?"

"Hmm... that's what makes this city special."

Just as Patchouli was saying this, several other people followed behind her.

They were a group of people from Eientei.

"Indeed, your observation skills are quite good, mage."

Kaguya Houraisan, with one hand covering her face with her sleeve, spoke with her usual elegant demeanor.

"Both Eirin and I can clearly perceive that there is a huge difference between this world and this city."

"Hmm, I think the Hakurei Shrine Maiden over there must have sensed it by now, right?"

Seeing that Eirin Yagokoro suddenly turned the conversation to her, Reimu Hakurei sighed lazily.

"Sigh, I can't really sense it that deeply either."

But what Reimu said was indeed her own feeling.

"This city does indeed have an aura that seems to emanate from within, an energy that is completely different from the energy that permeates the outer regions of this world, and is even... mutually repulsive."

You can understand this level of understanding simply by observing.

It must be said that the girls who came to Gensokyo all possessed extraordinary intelligence and talent.

If they could learn that the entire city is filled with things called AIM diffusion fields, and that the outside world is a magical world... perhaps they could try to understand it in a deeper way.

Then.

Who on earth managed to transform this city into what it is today?

The answer is at hand.

Accelerator and the others all turned their gazes forward to a very unique high-rise building located in the city.

The answer to everything lies inside this skyscraper.

Kakine Teitoku clenched his hands tightly, his eyes filled with a very complex expression.

I'm excited.

…there was also anger.

"Chairman of the Board, Aleister Crowley..."

The person he had always wanted to meet was in this tall building without doors or windows.

"Ready to go."

"Huh? We're going to go inside?"

Marisa looked ahead, somewhat bewildered.

This building is indeed very tall, but... anyone can see that.

There was no entrance, no exit, not even a window.

"That's really strange..."

Even Remilia, a vampire who prefers dark environments, couldn't help but frown.

“We vampires usually have windows in our homes, but this building doesn’t even have the most basic windows… Don’t the people living in here need any ventilation?”

In other words, the people living here are even stranger freaks than vampires.

"The most important question is, how do we get in?"

Alice moved closer to Accelerator and asked in a low voice.

One-way did not respond.

Rather.

He quickly answered everyone's questions with his actions.

——Swish.

After he pressed down on the necklace around his neck, six dark black generators appeared.

The first finger points slightly forward.

In an instant, a huge black spatial rift appeared on the surface of the building.

"Get ready to go."

Since there is no entrance, let's forcibly create one on the surface.

…That being said, there was actually an entrance not far from the building.

It's unclear who managed it, but the entrance was so small that it was impossible for all of them to get in.

Therefore, by using the One-Way Street method, everyone present could get inside.

Enter the building where the king of this city resides.

Chapter 682 A Notice from Aleister

There was absolutely no external interference.

Even if outsiders wanted to interfere, they couldn't do so at all.

The interior of the building has remained unaffected for many years.

Logically speaking, a building in this condition would definitely breed all sorts of bacteria and stains inside.

In the worst-case scenario, spider webs will be everywhere.

…But in this high-rise building, you can't use that common sense to think about all of this.

The deserted building has an ever-ascending staircase, but apart from that, its lower and middle levels are almost empty.

Even though there are no windows, it doesn't feel stuffy at all.

Even though there are no light bulbs anywhere, it still doesn't feel dim.

Various impossibilities, defying conventional Euclidean space, coupled with the building's exterior walls made of computationally induced, impact-diffusion composite materials that could not possibly be manufactured using conventional methods.

That's how this incredibly strange high-rise building was constructed.

then.

Having clarified all of this, we also have ways to deal with it easily and directly.

Swah——

That is spatial capability.

A teleportation portal was opened directly on the top floor of the building, at the location of the only resident living there.
