While browsing the history of this world, I happened to come across this troublesome point in the timeline and just happened to come and resolve it.

If we consider Accelerator's previous personality, no matter how many times he's reinvented, he would never do something like this.

That is precisely why it can better prove just how much one has changed.

Not only in terms of strength... but also in terms of the heart, which has undergone an unparalleled change.

The first one took a slight step forward and then vanished into thin air.

The location where he will appear next.

It was located opposite a residential building.

"It's finally sunny, aren't you going out for a stroll?"

"There's still a lot of water outside, isn't there? If you leave now, you'll still get soaked."

"Hey~ the drainage system should be fixed soon, right? No way, I want to go shopping on this special day~!"

"Of course I'd like to go shopping with you too, really... no matter how many years have passed, you're still the same."

"Hmm, is this an expression of dissatisfaction?"

"How could that be? I'm too busy feeling happy to even think about it."

A couple was staying in the house across the street.

No… judging from the atmosphere and the content of their conversation, they'll probably be getting married soon.

A woman with long black hair and wearing a contrasting colored hair tie.

With his short brown hair, he looked handsome and refreshingly clean-cut.

“I said, Taki.”

The woman stood in front of the man, looking at him expectantly.

"When we get married in the future, let's invite the Imperial Envoy and Sayaka as well."

"Of course I will! Not only that, I'll also invite my friends here."

"Really? That's wonderful! Then, Ms. Okudera will be coming too!"

"Of course, I already included her share."

"Huh? So, Taki, you haven't already started planning our future marriage all along, have you?"

"Uh... this, this..."

"Hehe...she's actually shy, how cute~"

"W-what? Why are you suddenly playing a trick on me?!"

"Ha ha…!"

Even after so much time has passed, these two people haven't changed in the slightest.

Accelerator watched them calmly, a gentle smile playing on his lips.

then.

In a spacetime that no one has ever observed.

The man with white hair and red eyes completely disappeared from this world.

"...It's time to go back."

Bang——! !

After crossing the boundaries of this world, the system that Accelerator had called upon finally responded.

However, the words "Host status is dead" are still displayed in the upper left corner of his menu bar.

But he didn't pay much attention to such things.

Because even without relying on the power of this system, Accelerator now has the ability to return to his original world on his own.

"Well, it's about time to bring this all to a close."

--------------------------------

boom! ! !

Since the Great Heatwave, such massive events have rarely occurred in Academy City.

However, similarly, the entire Academy City fell into a very strange atmosphere after the Great Heatwave.

Most of the students no longer remain in the city.

Some left the city for other places, while others simply went to other countries to avoid the holiday.

Because of this.

Within this utterly empty city, countless new people subsequently arrived.

"I always feel that even after that big heat wave, there's still an unpleasant feeling of heat."

"Your Majesty, you shouldn't be saying that."

"Huh? What's wrong? I just feel hot!"

"That's not what I meant... You're a demon god, is there really an environment in this world that can make you feel hot?"

"Oh right, I accidentally forgot that I am a demon god."

"Take away some of your airheadedness, you Corpse-Dissolving Immortal."

"What's there to be proud of? It's just that her breasts are a little bigger, damn mourner."

Not long ago, a facility resembling a giant microwave oven appeared in the skies above Academy City, plunging the entire city into an unparalleled sweltering environment with its intense heat.

Now, that kind of environment has dissipated, and the bitter cold that originally belonged to December has arrived.

But neither cold nor heat matters to these two people.

…wrong.

In a layman's sense, they are not even human.

The demon goddess Nephthus sat on a nearly deserted bench by the roadside, eating ice cream she had taken from a vending machine without permission.

"Is that stuff tasty, Nephtus?"

"It's very sweet, but it's too early for a little kid like you."

"Of course I know it's ice cream! Just let me have a little taste!"

"Ugh, why don't you just go to that vending machine over there and get another one... Ugh, really."

Ignoring Nephthous's wishes, the Queen snatched the ice cream from her hand and ate it.

However, my tongue was ice-cold after just the first bite.

“It’s so cold!!”

"You took too big a bite, and I've already told you, you're a demon god, how could you feel something's wrong over such a small thing?"

"Stop arguing! Doesn't a demon have the right to pretend to be frozen?"

The empress, who was still licking her ice cream, also sat down on the bench.

Judging from this, it seems that there are only the two of them on this street.

However, the Empress spoke up soon after.

"Where did that little girl run off to again?"

"You care a lot about her?"

Swah——

It's unclear how, but after Nefutus's bandages were wrapped around the ice cream in the empress's hand, the exact same ice cream appeared in her hand the next instant.

"That child has had a tough time, it seems he's searching for someone we don't even know."

"...What does that mean?"

"It means exactly what it says. She seems to keep saying that there is a human being that we used to know, but who was erased for some reason, who exists in this world."

"How could there be something that even we demon gods don't know? It must be fabricated, right? Look, it's like that kind of delusional disorder, where a mental patient directly imagines a friend or something."

"Who knows, but..."

Nefertus was still licking the ice cream in her hand.

"I don't think the feelings in that child's eyes were fake."

————————————————————————————————————

And so, in a corner of this academy city...

The girl stayed there alone.

Long, azure blue twin ponytails, and eyes as beautiful as jewels.

only.

Those eyes had become utterly cold and indifferent.

She walked alone, dressed in a dark blue evening gown, slowly through the vast, factory-like area.

pat.

The originally dark and gloomy room instantly became bright.

"Although I had heard about the recent intruders in Academy City, seeing them in person was still quite a surprise."

"I've never heard of or even imagined a world-famous idol acting as an intruder before."

"I'm warning you beforehand, don't be fooled by how simple this girl seems, she's actually a very troublesome character."

"Don't worry, since you, as the number one, have said so, we'll naturally be more careful as well."

Three people appeared inside the warehouse.

A blonde girl wearing a pink halter dress.

A high school girl with red hair, holding a police baton.

A tall young man with brown hair stood in the center.

The prison is colorful and the sea is beautiful, the knot is light and clear.

And, Kakine Teitoku, the number one Level 5 esper in Academy City.

These three people seemed to have been prepared all along, revealing their true forms as soon as Hatsune Miku entered the warehouse.

however.

The girl did not stop walking.

She seemed to completely ignore the three people, and simply walked slowly toward the interior of the warehouse.

"Hey...can't you see us?"

"That guy is really annoying."

Both Kihara Ayaki and Yuki Ayami showed displeasure.

"I told you, that guy isn't someone you can just deal with easily. Otherwise, why do you think that bastard chairman made me come along with you all..."

"Okay, whatever it is, it doesn't matter."

Kihara Tatsuki, whose ideology prioritizes attack, immediately took action.

"No matter what kind of person the other party is, let's start with a straight shot!"

boom--! !

On the left and right sides, boxes containing heavy objects were instantly manipulated and thrown directly in front of her.

It landed right above the girl's head.

Boom!! The huge box crashed onto the ground, causing the ground to collapse instantly.

however.

After doing all this, Kihara Tsurugi frowned instantly.
