"Tsk, what is this? If that's all you've got, you might as well have come to me directly and let me stab you to death in one go."

The white-haired, red-eyed boy spat in boredom, then casually lifted his foot as he moved closer to the girl.

"Whatever, I'm not in the mood to continue playing anyway."

"O...saka..."

"Hmph, after I kill you, I'll go back and take a good shower, and then eat the fried chicken I just bought."

Ugh... I hope there's no bits of this guy's meat in the fried chicken. No matter how disgusting I am, I wouldn't eat human flesh, would I?

This is what Accelerator, the strongest Level 5 esper in Academy City, thinks.

Therefore, in the final moments, he had no intention of holding back at all.

Without hesitation, he stomped his right foot down on the girl's head.

Puff——!!

Like a watermelon bursting open, countless drops of blood sprayed onto the wall—this was probably an inevitable result.

"…ah."

However, the girl did not die.

Because the source of this blood is from one side of its abdomen.

A hand ruthlessly pierced through his stomach.

"Wh...this...this—Pwaa ...

The intense pain reached his brain, causing him to faint instantly without even uttering a cry.

puff!

The pale arm was pulled out from the other person's abdomen. The person calmly stared at the fallen strongest ability user and kicked him away as if he were trash.

Of course, even so, he is still the strongest ability user, so he probably won't die.

However, because Accelerator had never been injured before, the sudden pain caused him to faint instantly.

"…you…"

The girl lying on the ground—Misaka Sisters—stared at the person in front of her in disbelief and in a daze.

"Who are you?"

At first, she couldn't see the other person clearly because he seemed to be wearing some kind of very dark clothing, and in the darkness, it was impossible to see his figure at a glance.

But things are different when the moonlight shines in.

The girl noticed that his appearance bore an extraordinary resemblance to the first-place winner.

White hair, red eyes, only with even thicker hair, giving off an overwhelming sense of madness.

Not only that.

On that predominantly black garment, there was a distinctive black and white design, much like the shape of eyes.

She looks...like an angel.

The other party didn't speak.

However, a streak of purplish-black light flashed behind him, and after that, Misaka Sister felt a warm sensation all over her body.

In other words, all the injuries disappeared in an instant as if they had never happened.

It was as if time had been turned back to the moment before I got hurt.

"Who exactly are you?"

He still did not respond.

After glancing sideways at the Misaka Sisters beside him, he put his hands in his pockets and slowly walked out of the street.

When Misaka Sisters walked out of the alley and looked outside, they couldn't find anyone at all.

Only when he fell to the ground in the distance, attracting a large crowd of onlookers, did he pass through.

He lay there on the ground, and the absolute defensive barrier formed by the power of vector manipulation could not protect him at all.

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

And things like this happen constantly in one world after another.

The one who accomplished all of this was, of course, Accelerator himself.

It can be said that he spent some time personally traveling to all the worlds where "Accelerator slaughtered the Misaka Sisters" and stopped it all at its source.

In this world where magic and science intertwine, parallel worlds should not exist in an infinitely extending form.

However, this is merely the perspective of people in this world.

Only Accelerator, who transcends the limited concept of the world, can see that even those powerful beings who believe that there are no other possible branches in this world are still wrong.

If we describe the world as a book, then the idea that "parallel worlds do not exist" is merely a setting known only to those within the work itself.

If other viewers who have seen this world were to rewrite the story of this work and depict it in the form of fan fiction or other derivative works, at that moment, a world equivalent to a so-called "parallel world" would be born in some unknown corner.

Now, Accelerator is heading to all the worlds where such things have happened.

He arrived in a world where every Misaka Sister had been threatened, and at the source of all these threats, he completely stopped the experiments on the Level 1 users.

Although his very existence cannot be rewritten in any way, this actually helped him to further prevent this series of events from happening.

For example, now.

"Stop it... Let her go! You scoundrel!"

Kamijou Touma, the spiky-haired high school student who rushed to the scene, was looking ahead with extreme anger.

Amidst countless shipping containers, the figure of Misaka Mikoto is being trampled underfoot.

"Get away from Misaka Mikoto! What... huh?"

Everything should be proceeding as planned.

The enemy being rebuked, the boy rebuking him, and the girl waiting to be saved.

Something seems to have gone wrong.

Kamijou Touma stood there in disbelief, his mouth agape at the sight before him.

Accelerator is the strongest Level 5 esper in Academy City.

That guy dressed in black and white, now...

Is someone stepping on the ground?!

"What... is going on?"

And that person looks exactly like Accelerator?!

"What on earth happened? Could it be? Even the number one ability user has clones?!"

"…Hey."

Stopped.

The Misaka Sisters, who were standing to the side, also looked over in great surprise, though of course, she was unharmed.

And that white-haired, red-eyed man with his hands in his pockets, dressed in eerie black clothes, his hair disheveled to the point of looking like a madman.

He gave a calm, yet terrifyingly oppressive laugh.

"Although this all happened so suddenly for you, this is exactly the effect I wanted, so it doesn't matter."

"Wait--"

"As for you, I'll have to give you some extra food."

The number one in Academy City, the master who transcends the concept of infinity and connects all worlds, the one who defeated the Gray Wings who created the world, and the one who transcends the realm of gods with a non-god's body.

With a whole host of such titles, Accelerator looked at Touma Kamijou in front of him.

"Since the guy you were originally supposed to fight wasn't challenging at all, why don't I play with you instead?"

"Don't worry, you'll thank me later for giving you more combat experience... I'll go easy on you at first."

then.

Six generators emerged from behind the first figure, and a fiery red scythe appeared in his hand.

Invisible wings slowly burst forth from behind him.

"You must be tired from the performance, so... isn't it time for a thorough cleaning?"

"If you can last ten minutes against me, then you've got guts, kid."

Before Touma could even react to what was happening, an opponent of far greater size charged towards him, seemingly holding back in every way.

The night in Academy City then ushered in an unprecedented period of revelry.

Chapter 866 Each Person's Path in Life

"This is really troubling."

In a massive skyscraper in Academy City, almost in the very center of the Seventh School District.

This is a building facility without doors or windows.

Despite having endured numerous acts of destruction and unimaginable suffering, given the passage of time, the building has been restored.

Now, the city has returned to peace, and the high-rise building has also returned to its former tranquility.

Right now, right here in this building.

The humans, immersed in countless liquids, then spoke.

"I never imagined he would choose to travel back in time."

Aleister Crowley, a magician.

As the chairman of the board of directors of Academy City, after experiencing events such as his trip to England and his encounters with the magical society Gold and the great demon Coronzon, he has now returned to the building where he was before.

A huge instrument, like a test tube filled with orange liquid, is a life support device.

In reality, Aleister no longer needed such a thing to sustain his survival.

All the "Crowley Frenzy" have been slaughtered by his nemesis, the mage Mathers, and after the slaughter, the power that Crowley possessed will be added to Aleister's main body.

In this way, the man with over a billion possibilities is no longer the same body that needed life support devices to survive.

Nevertheless, he still chose to stay inside the device.

Is it because they've gotten used to living here? Or is it for some other reason? No one else knows.

"But upon closer reflection, it's not that complicated. After all, everyone would have such thoughts. If they had the ability to travel through time, they would probably first want to understand the mistakes they made in the past."

Another voice came from the darkness.

Platinum-gold light exploded in the room where Aleister was, but the chairman of Academy City was not surprised at all.

Without a doubt, this is the supreme and holy being who has been by his side until now.

"What's truly surprising is that the so-called 'past' actually exists."

Holy Guardian Angel Aiwass.

After the series of turbulent events, the angel who had made a pact with Aleister returned once again to Academy City, where AIM diffusion fields filled the air.

However, its appearance actually drew some attention from Aleister.

"Oh? You're actually willing to stay by my side."

"Oh My God."

Aiwas's voice seemed to have become somewhat feigned innocence.

"It seems I've been exposed. I once considered siding with that Rose Maiden, and even that seems to have been seen through."

"Looks like you've already confessed. Oh well, I'm too lazy to pursue this any further."

Anna Sprenger, a magician from the Rose Cross magical society.

Aiwas originally seemed to genuinely intend to side with that legendary mage, and had even prepared to elevate his body to a higher level.

However, all of this seems to have been forced to end due to the actions of a certain number one player.
