『 Now, IT IS THE STORY OF THE HUMAN ALEISTER—!!!
The Golden Dawn society, founded during the age of steam, gradually disintegrated as the times changed.
And after that, what did Aleister do?
Kamijou Touma continued to climb the final stretch of the transparent, spiraling staircase, and finally, he reached the end.
And then—what connected to the ladder reaching the heavens was… an endless universe.
So vast, so insignificant; Kamijou Touma felt his own insignificance once again in an entirely new way.
He had no idea what kind of distortion had befallen the dimensions inside and out, but beneath his feet lay the massive blue planet extending into infinity.
"It's simple," a figure with long silver hair reaching their ankles, wearing green surgical scrubs—looking like both a man and a woman, both an adult and a child, both a saint and a prisoner—stood before Touma.
Looking at Kamijou Touma, he spoke softly, "The ley lines coursing through the earth govern space, thereby forming a field; magic born on Earth is magic restricted by Earth."
"By the same logic, those humans subject to heavy interference from sparks must either flee this planet or remain restricted everywhere." 』

Academy City—
Saten Ruiko watched the conversation between Aleister and Kamijou Touma on the screen. The girl was stunned for a moment, then her gaze quickly shifted to the Windowless Building.
She hadn't thought about it before.
But after Aleister's remark about fleeing the planet, Ruiko felt that the more she looked at that pitch-black Windowless Building, the more it resembled a…
Rocket???
Could it be that this Board Chairman is prepared to launch himself into outer space at any moment?
After all, they had seen before that even Academy City's strongest esper, Accelerator, used the energy of the Earth's rotation to bombard this Windowless Building.
But other than racking up a mountain of debt, Windowless Building remained completely unscathed!
And the words that followed on the screen proved that this was indeed the case—
—
『 The sturdy walls, the fully recycled environment, the rocket boosters—all were prepared for this very purpose.
But even if these conditions for escaping Earth were destroyed, it would not matter, because he had long since ignored Euclidean geometry, stretching space infinitely to build a tower of another dimension.
He had cast off the shackles of the sky!
"…Is your battle still not over?" Touma looked at the figure and said silently.
"Perhaps it will never end. I use life-sustaining equipment because I do not want traces of my life force to leak to the outside world, and I have set a limit of 1700 years for myself."
"I don't think Lilith would love this version of you," Touma said, uttering what he considered to be a vicious remark, and then the battle between the two began.
At this moment, it is Kamijou Touma vs. Aleister! 』
『 .....』
〜Three-Body Problem World〜
Countless civilizations in the Three-Body world widened their eyes, looking at Aleister on the screen.
Is this the person below the Magic Gods in that world, the Academy Board Chairman who founded the Science side?
Although most civilizations had never heard of the Euclidean geometry mentioned by the other party, that was just a name.
It should refer to the law that, simply put, given a point not on a line, there is one and only one line that does not intersect said line.
In simple terms, it is a law of the universe.
The names differ, but the laws of the universe are universal. If that world lacked magic, it would be extremely similar to their own.
In other words, in the realm of science alone, has Aleister already surpassed them? Or is this transcendence built upon the fusion of magic and technology?
After all, they knew clearly that Aleister was a super-hardcore existence capable of unleashing a destructive impact ten times that of a cosmic Big Bang.
Even if such an existence is not a Magic God of that world, how far behind could he really be?
The Three-Body world greedily absorbed all the knowledge, but at the same time, they grew increasingly fearful. Every civilization feared being discovered by more advanced civilizations, and feared even more that this world contained such power capable of instant destruction.
The more they knew, the more they feared.

Hidden World—
In order for the world to return to its original baseline, the Magic Gods made a wish. This wish attached itself to the Saint's right hand, ultimately giving birth to Imagine Breaker.
And now, Aleister intends to use this Imagine Breaker to end magic, shatter mystery, and eliminate phases?
Even to kill gods?
This… is getting more and more interesting.
The Magic Gods, thinking of this, couldn't help but feel a bit of amusement.
—
〜Type-Moon World, ????? Worldline〜
The magi fell into deep thought.
Magic, that is, mystery, is completely opposed to science. In other words, they cannot coexist.
There is a saying that mystery is called mystery because it is unknown; once it is widely exposed, it will bring unprecedented influence to the mystery.
But saying that conflicts with the previous Great Qin Lostbelt and Greek Lostbelt, as they had seen with their own eyes the fusion of mystery and technology in Great Qin and Greece.
And now, there is another big shot who fuses technology and mystery. For a time, reformers like Lord El-Melloi II found their thoughts becoming increasingly active.

『 Viewers of Myriad Worlds 』
Although everyone looked forward to the battle between the two, it seemed there was no suspense.
This battle was destined to be fruitless. The probability of Kamijou Touma defeating Aleister was extremely low, and the probability of Aleister killing Kamijou Touma was zero.
Because they could see that Aleister valued Kamijou Touma too much. To accomplish his grand wish, the one thing he absolutely could not lack was Kamijou Touma!
.....
『 The battle began, and Touma rushed toward Aleister, brandishing his fists as always.
But the gap between the two was like a chasm. Aleister could even proudly say that no one understood Kamijou Touma better than he did.
Under the explosive power of the Blasting Rod, Touma had no power to fight back and was soon covered in wounds, but a glimmer of realization appeared in Touma's heart.
Aleister was determined to eliminate all magic, which meant he had to be an enemy to the Magic Gods. Without exceptions like Kamisato Kakeru's World Rejector, how could such a goal be achieved?
But now it seemed Aleister had already designed this mechanism. Since it could not be done with a human body, he would provoke the destruction of the Magic Gods.
Maintaining a human body, borrowing the power of gods to kill gods!
Not to become a member of the gods, but to manipulate and dominate them! 』

〜A Certain Magical Index World〜
World Rejector?
The Magic Gods were thoughtful, and soon they understood what the World Rejector mentioned by Kamijou Touma was.
It had the effect of banishing those who, because their wishes were repetitive and thus yearned for a new world while clinging to the present, to the remaining areas of the same timeline—the other worlds—thereby erasing their existence.
And the reason for its birth was also very simple. They did not know about World Rejector; it was a power born from the future.
And there was only one source for the birth of this power: the wishes of the Magic Gods.
Clearly, this was because in the normal timeline, Kamijou Touma had won in his confrontation with Othinus, but ultimately became the only one who understood Othinus.
Imagine Breaker could no longer put them at ease, so some Magic Gods sought substitutes for Imagine Breaker. Power leaked, and thus World Rejector was born.
As for Kamijou Touma's speculation about Aleister, the Magic Gods did not deny it. Aleister was indeed such a wicked guy.
But it was precisely because such hatred resided in his heart that it led to such ultimate arrogance!
Many Magic Gods even hoped to see Aleister again. How about beating him into a billion… no, twenty billion pieces then?
—
『 "Don't think it's over yet," Aleister suddenly reached out and pointed at the empty sky.
He seemed to be chanting something, "Reaching out to touch the karma of man, the demonic nature of the mountain inciting from behind, why did I drive you all the way here, why did I let you pursue my past?"
"This is all part of the same ritual—"
"Rise, Aiwass. Guided by the chains that bind thought, fulfill my long-cherished wish!"
Touma looked around vigilantly, but nothing happened…?
NO!!!
The next moment, a light brighter than the sun filled this temporary universe!
Golden hair and a dazzling body; cold, pale gold radiated from every inch of him.
…Holy Angel. Such words flooded Kamijou Touma's mind. 』
『 .....』
〜Gabriel DropOut World〜
Gabriel frowned. This angel… was terrifying to an unimaginable degree?
Aiwass? A Holy Angel completely unrelated to their world? The power within him had reached a shocking level.
Even her sister was a mere amateur in front of her. Gabriel was certain that while the opponent was not as strong as a Magic God, destroying that universe would be nothing more than a wave of a hand.
Perhaps that angel called Aiwass was even summoned by Aleister to counter the Magic Gods!
—
『 Kamijou Touma looked at Aiwass before him in shock, so holy, so dazzling…
Aiwass greeted Touma, then He actually laughed. Under Kamijou Touma's shocked gaze, Aiwass laughed, "Now is not the time to worry about such trivial matters."
"After all, I am your natural enemy now."
The next moment, something exploded—
Before his brain could react, Kamijou Touma's right fist had already swung out, but even with that reaction, his right hand still presented a strange, twisted sensation.
The Invisible Thing that flew out from it was also easily crushed by Aiwass.
"Ignorance is truly terrifying. You actually thought to entrust your life to the distance of a three-dimensional concept in this box garden where Euclidean geometry has collapsed," Aiwass sighed.
Then, intense pain struck. Kamijou Touma roared in agony, his face deathly pale, and bouts of tinnitus assaulted him, but the boy still heard these words.
"Blasting Rod—"
Touma's pupils contracted violently. The next moment, Aiwass's figure expanded several times over, and the energy within his body expanded ten times again!
Touma endured the excruciating pain to reset his joints, then reached out to desperately resist. Grinding, horrifying sounds exploded from all parts of his body! 』

[ Kenjaku (Jujutsu Kaisen): "The gap is too big. And unlike Othinus, who had flaws before, Aiwass here is completely Aleister's tool~" ]
[ Othinus (A Certain Magical Index): "…I had flaws?! Speak clearly! Otherwise, be careful, or I'll blow you up!" ]
[ Misaka Mikoto (A Certain Magical Index): "Idiot… always thinking about saving others alone. What's the point of saving the world?! You still have us behind you!" ]
[ Fiamma (A Certain Magical Index): "Ten times… even if this is ultimately just a ten-fold effect based on the limits of human imagination, its destructive power is still unimaginably large. This is enough to give credibility to Aleister's arrogant act of going to war with the Magic Gods." ]
[ Mahito (Jujutsu Kaisen): "Touma-chan is being brutally tortured again. This time, won't he have to cycle through hundreds of millions of times again? That would truly be most unfortunate~" ]

〜A Certain Magical Index World〜
"Kamijou Touma,"
Aiwass murmured.
In his observations, the two protagonists of this world already had shapes. As for the remaining one, although the colors were not yet distinct, it could already be determined.
Kamijou Touma—the person who forged ahead following only the emotions welling up within his own heart, without ever receiving guidance from anyone.
Accelerator—the person who committed great mistakes in the past, suffered for his sins, and wanted to reform and walk the righteous path.
And Hamazura Shiage—the person not chosen by anyone, possessing not a shred of decent aptitude, but who stood up to become a hero to protect the person he cherished most.
These were the representatives of humanity, and also the people She watched. She looked forward to their future… simply because She found it interesting.
On the other side, seeing Touma being so brutally tortured, a trace of anger couldn't help but flash in Othinus's eyes.
But she also sighed. Aleister had always used the word science in a positive sense.
According to his thinking, whether it was on a physical or spiritual level, as long as one could properly arrange the sequence and explain the causality within it, that was science.
In that theory, Aiwass was at the apex. She did not belong to any religious place; She was a Holy Angel formed in this world by stacking multiple magic-side phases on top of physical laws.
She was a Holy Angel standing in a world of pure physical laws.
The beautiful blonde girl revealed a look of solemnity.
Perhaps… as long as one could perfectly devise a way to dominate Aiwass and use that vast energy to destroy all filters other than Aiwass, a world without magic would be born afterward.
However, that was too difficult. The difficulty was absolutely no less than Aleister taking on all the Magic Gods single-handedly.
—
『 Just as Touma was about to die at the hands of Aiwass, that cat-eared nun suddenly appeared in front of Touma and blocked the blow!
The first to be shocked was not Touma, but Aleister on the side!
"Wh…what?!"
"In that era, you chose me. In fact, you had already foreseen this failure, so you hoped I would defect to Kamijou Touma's side, right?!" Aleister said in a low voice.
Aiwass, on the side, laughed in a gloating tone, "I see. Aleister, it seems you have failed again."
Touma did not understand why Mina, the cat-eared nun who should have been a phantom, appeared here again.
"I am an artificial intelligence established inside the Windowless Building, an arithmetic machine for Aleister's plan correction. What exists in my central processing unit are the 78 Tarot cards that make up the administrator. I am the archetype of the Tarot cards."
Both sides were Aleister's masterpieces; for a time, it was hard to determine a winner!
And just at this moment, an attack came from the outside again!
While Touma was fighting, Othinus and the others were not idle. They destroyed Aleister's perfect structure!
And Aiwass, who should have been the strongest, was also disrupted by the attacks of the crowd and easily disappeared.
And Mina was so weak that she could no longer maintain her body and dissipated on the spot again.
And at this moment, in this Windowless Building, only Aleister and Touma remained.
"…I will erase this illusory scene, filled with phases and sandwiched by countless colored lenses." Aleister had suffered countless failures so far, but he would absolutely not change his stance!
He looked at Kamijou Touma and roared, "I will destroy all phases!"
"Correct this world that is being manipulated, which no one knows about! It's not just Lilith's death; I will reshape the world that considers tragedy to be helpless and therefore buries it! FOR THAT SAKE… I!!!"
"…Don't you think that even those ethereal things are sometimes protecting people's happiness?" Kamijou Touma spoke, staring straight at Aleister! 』
『 .....』
『 Viewers of Myriad Worlds 』
Everyone looked at the hysterical Aleister, unable to understand.
Does one really have to destroy all phases and magic to change the misfortunes of the world?
Couldn't Aleister work harder, reach the Magic God realm, and then surpass it? Aleister had the aptitude for that, right?
At that point, wouldn't it be better to directly modify the origin of the universe, change the power system, and solve everything from the root?
In their view, what Aleister was doing was like the decline of the Age of Gods in the Type-Moon World.
Even the World/Gaia was resisted by countless existences, let alone Aleister, a human, trying to change the entire world?
In the Type-Moon World, Aleister would at least be a Beast…

( Translator-kun: Regarding Aiwass's gender, the author knows that Aiwass is genderless, but since the catalyst used was Aleister's wife, the author refers to Aiwass as 'She.' )
