“…… Although there are many mysteries about the truth that governs this world, it is impossible to change the reality of the existence of magic and demons. This "Demon Special Zone" itself exists to find out this mystery, isn't it? ”

"You're a good student, Sword Witch."

There was a hint of sarcasm in Sendu Mu Aye's tone.

"So, haven't you ever doubted the raison d'être of demons and magic? A single vampire has been endowed with the power to destroy a huge city - can you dare to assert that an unbalanced gesture like this is the proper way for this world to exist? ”

"That's ......"

Yukina couldn't help but be speechless. It was a natural question that everyone would have once they understood the threat of the True Ancestor. Why are they the only ones endowed with such great power?

The fiery witch looked out the window. The side of the face was so kind that it was impossible to overlap it with the impression of her brutal and unscrupulous demon offender.

"I've been wondering if whether it's demons or magic arts, they all exist only in people's imaginations. And a world where there are no such things is the right attitude for this world. ”

"But, the reality is that the power of abilities exists, even if they're wrong."

Yukina glared at Xiandu Mu Aye and said. And Ah Ye grinned at the corners of his mouth.

"That's right, that's why I said that this world is cursed."

"Maybe that's the case. But human beings still live in this world, for thousands of years. ”

The Fire-Eyed Witch, who listened to Yukina's words, suddenly became serious and tilted her head.

"It's been ...... for thousands of years Yes. Is it really like you say? ”

"What does that mean?"

"Do you know the idea of the five-minute pre-world hypothesis?"

After being asked by Ah Ye like this, Yukina shook her head. That's a very ear-scratched term.

And the fire-eyed witch did not despise Yukina, who was bewildered by this, but explained it blandly.

It is the hypothesis that the world became what it is five minutes ago, and that it did not exist before. It is believed that whether it is human history or memory, or the records and buildings of the past, they were all made by someone five minutes ago. ”

“…… It's just a simple hypothesis...... It's just a thinking experiment that can't be proven. ”

Yukina pointed out the point with a sigh. This hypothesis cannot be refuted. However, at the same time, it cannot be proved to be true. I really can't imagine that this hypothesis has the significance of philosophical thinking.

But Ah Ye smiled happily as if he had been waiting for this rebuttal for a long time.

This is indeed a hypothesis, however, there is a way to prove it. As long as I can succeed in creating the world at will according to my own preferences in reality, you won't have room for doubt, right? ”

Understanding the meaning of Ah Ye's words, Yukina's face suddenly lost its blood.

"Do you ...... That's what it's all about...... That's why I ...... with a secret oath! ”

"I didn't ...... Wrong. I wanted to rewrite the world, and I did an experiment to do it. ”

The fiery-eyed witch declared without hesitation. Yukina shuddered at this and trembled her shoulders.

The true purpose of the "Witch of the Secretary" Sendu Mu Aya is not to destroy the power of the supernatural powers.

She is planning to rewrite the world, to rewrite it as the correct world for herself.

"Why did you do such a dangerous experiment on the island of the String God......!?"

"This is the 'Demon Zone' - an artificial island that would not have existed in the world without magic. It's a symbol of this crazy world. There's no better stage for my experiments, right? ”

Xiandu Mu Ah Ye explained boringly. It was as if he was saying, "Why do you want to ask such a matter of course?"

Yukina suddenly felt nowhere to vent her anger and glared at the other party.

"Is that why you're going to kill hundreds of thousands of people for this kind of thing?"

"This is the retribution that has reduced our witches to a taboo existence and used them as they please...... Yes! ”

The fire-eyed witch shouted roughly. That was the first time Yukina had seen the other party's emotional behavior.

"You saw it through your eyes, O Sword Witch? My ally, Nangong has been subjected to how they have been treated that month-! ”

"Sendu Mua Night...... You ......"

With a confused expression, Yukina looks at Aye, who is struggling with breath from irrepressible hatred.

During the battle in the prison enchantment, Ah Ye didn't kill Nayue, even after taking away Nayue's memory and letting the other party run to a safe place, he didn't do anything to chase after him.

Even now, even if he was captured in a powerless state, he put revenge aside.

Sendu Mu Aye, she may not want to fight that moon in the end. During her time in prison at the prison barrier, she may have been thinking about the month she was left alone.

For Ah Ye, that moon is really an ally that can be called an existence.

"To activate the Secret Oath, you must use the spiritual power of the dragon veins flowing in the 'Demon Special Zone' and the power of the stars. The reason I've been dormant in the prison barrier for the past ten years is because I've been waiting for the stars to be arranged. There is only one night left, and at the end of the Haha-in Festival, my world will be gone. ”

Ah Ye, who finally calmed down his breathing, returned to his original tone and said.

This is an unexpected and beneficial information for Yukina. Tomorrow morning, when the position of the celestial bodies changes, the dark oath will lose its power. However, it is inconceivable that the ancient city, which lost the power of a vampire and was badly wounded, would have survived to that time. And before that, the island of the string god that continued to collapse didn't know what would happen.

"Of course, the island must have sunk to the bottom of the sea by then. In order to prove the correctness of my hypothesis, this experimental result is still necessary. ”

Goo, Yukina groaned bitterly, then clenched her spear. But the current Yukina, who is imprisoned in a birdcage, has no way to stop Aya.

"That gun...... the "Type Seven Assault Demon Slaying Machine Gun" says it has the ability to nullify all mana and tear through any barrier - that's right. But ah, could that be true? ”

Looking at Yukina who was holding the spear tightly, the fire-eyed witch suddenly changed her tone and said.

Feeling like she was criticizing her favorite weapon, Yukina put on a prickly expression.

“…… What the hell are you talking about? ”

"I wonder if it's not neutralizing the magic, but restoring the world to its original state, right? If it weren't for that, I don't think there would be any other way to explain its power that could be neutralized along with the power of the True Ancestor. ”

Ah Ye smiled leisurely and informed, her fiery eyes looking at Yukina as if she were watching closely.

"In that case, who are you who can use that gun freely, and are you really a human being in this world?"

"--Did you bring me here because of such a frivolous guess?"

Yukina suppressed the wavering in her heart and said in a flat tone.

So far, I have not been able to understand why I was taken captive, but now this question has finally been solved.

Sento Ki Aya became interested in Yukina as a user of the "Type Seven Assault Demon Slaying Machine Gun". Speaking of which, when they first met at the prison barrier, Yukina's gun caught her attention.

"Speculation. I wish you, then, would tell me why you alone could break free from the effects of the oath and use spells as you always did. ”

Sendu Mu Aya asked Yukina in a teasing tone. Yukina is silent because of this unexpected question.

A little doubt spread in my mind. Perhaps, what the fire-eyed witch said was the truth. It's all about the truth about this world.

"You, just said that the current posture of this world was made by someone, right?"

Yukina asked Aya in a stiff voice.

"That's right. It might be more appropriate to give a curse than to make it...... Point it. ”

"Who the hell did that?"

"I don't know. If you want to talk about the existence that created this world, you should call it God.

But it shouldn't be such a high-level existence. ”

Ah Ye shook his head unpretentiously. Then she smiled at Yukina as if she remembered something.

"Speaking of gods, it is said that the true ancestor was born by the curse of the gods, right?"

"So, what's wrong......?"

"In that case, who is the fourth True Ancestor who shouldn't exist in this world......? Whose will was it that gave birth to it? If you know this, you may be able to decipher the secrets of this world—"

Ah Ye's words were broken in the middle of the way. Then he looked out the window as if taken aback.

“…… What is this magic!? ”

Yukina also sensed the reason for Aya's consternation at this time. An extremely dense wave of magic power was shaking the atmosphere, shaking the atmosphere of the world dominated by Ah Ye.

"How is that possible?"

After spitting out such a sentence, Ah Ye moved to the playground, along with the birdcage containing Yukina and them.

Wrapped around the school was a silvery cloud.

The scenery outside is obscured by a thick fog and cannot be seen. No, it's the whole city that changes to the silver haze.

Yukina's eyes are looking at the monster lurking in the clouds through spiritual vision.

A carapacemon that does not hold entities like undead. This fog is the vampire's beast, the beast of the fog that wraps the entire island of the string gods. There is only one person in this "Demon Special Zone" who can use such a powerful beast.

The silver mist is blocked by the invisible wall.,Can't enter the territory of the school park.。

The barrier opened by Xiandu Mu Aye is blocking the invasion of the silver mist.

But the thick walls suddenly cracked. Someone is tearing apart the barrier along with the space, intending to invade the world of Aya.

"--Run here, Beast No. 3, 'Mercury of the Dragon Serpent'!"

It was an existence capable of swallowing up the entire space, the Dimensional Devourer. And the envoy of the intertwined mercury double dragon, breaking the closed school gate, is the strongest vampire in the world wearing a bloodstained coat.

The fourth true ancestor, Xiao Ancient City.
