The overseeing chairman of Academy City, and also the most feared magician in the world.

He squinted slightly, as if recalling something.

"No... if we go back to the previous timeline, I should have appeared many times by now, right?"

"...So you really knew about these things."

Upon hearing the sound, Aleister turned his head.

Hatsune Miku.

The excited girl strode quickly toward him, her voice trembling with excitement.

"The overall chairman of Academy City... So you're someone who remembers the previous timeline too?!"

"You didn't just find out about this information now, did you?"

Aleister maintained an expression that was almost frighteningly calm.

He continued speaking.

"I know more than just these things."

"I also know that you and Accelerator... both of you possess the ability to travel between different worlds and acquire different powers."

Is that what happened?

"The host of the soul system."

thump--

At that moment, Hatsune Miku seemed to feel something.

My heart skipped a beat.

This means that she is not alone in this world.

Chapter 737 Challenges Faced by All Parties

"you…!"

How is this possible...?

These words alone completely terrified Hatsune Miku.

The information contained in these words goes far beyond simply the other party knowing about this past timeline.

He even knows about the system.

"What's going on...? How did you know...?"

"Yes, how do I know these things?"

It's clear that Aleister knew far more than just these things.

There is an even greater secret about him.

"But compared to that, what's more important right now is the matter at hand, isn't it?"

The things that are truly important enough for everyone to take seriously.

"Now, even a power level like a demon god is becoming a strange and incongruous thing."

"You damned human, if you utter another word, I'll tear your head off right now!"

The humans who casually mocked the demon god, and the empress standing to the side gritting her teeth.

However, what Aleister said, while puzzling, was in some ways close to the current reality.

The power level of the demon god is no longer simply the strongest.

At least, that's the case for now.

What should we do?

Hatsune Miku stared at Aleister, asking him anxiously.

"How can we save this world? I... I no longer want this world, which has already been saved once, to fall into a hopeless and tragic future again!"

"Hmm, so you're saying that even though you're the one who caused this riot in this timeline, you're still trying to save it, right?"

Well…

For a moment, it felt as if my heartbeat had stopped again.

The girl's expression turned ugly, and she even couldn't help but take a step back.

The reason is what Aleister said.

The enormous crisis the world is facing today... is actually caused by Hatsune Miku.

If she hadn't done these things, the demons wouldn't have known about the existence of another dimension, and they wouldn't have connected this world's passage to that dimension.

...and thus, the being over there wouldn't be aware of this place.

"However, even if you don't do these things, the other side will probably still invade this area in the future."

"Why?"

"Because things from the previous timeline still remain here."

After saying that, Aleister turned his gaze directly to Hatsune Miku.

This is referring to both Hatsune Miku and his own story.

"I retained my original memories for a different reason, while you did so because of that system."

"But either way, it's something we shouldn't have. That guy will find out about all of this and will soon choose to attack."

That guy… Hatsune Miku immediately noticed the way Aleister addressed him.

"Do you... know what the enemy's true face really is?"

"Of course I don't know, and it's impossible for me to know."

The world-renowned magician then shook his head.

"However, just because I don't know doesn't mean that others don't know."

"Who...who is it?"

Who could it be?

Hatsune Miku immediately followed up with this question, however—

"...Speaking of which, that's a bit tricky."

Aleister's eyes narrowed.

"Even if I really wanted to say that person's name, it's actually a word I can't understand at all."

"Varied--"

"It should be said that it is because the level is too high. Overly obscure words cannot be expressed directly through words, let alone with a simple mortal body."

Although he knew the other person's name, he had no way of expressing it in any written or spoken language.

"Wait a minute, the feeling you're describing, could it be related to your precious angel Aiwass?"

Aiwass.

Now that you mention it, it seems like I have some recollection of it—Hatsune Miku also began to recall.

Previously, when Hatsune Miku was attacked here by Aiwass, she had at least heard what the Platinum Angel had said.

It was like gibberish, a bizarre and completely unacceptable language.

"While I am pleased that you have compared my research findings to that level of existence... the gap is simply too large."

Aleister directly rejected the Empress's statement.

"That is not something you can fathom, nor is it something I can contemplate."

"Who is it? Stop with the old riddle game! You really want me to slap you to death, don't you?!"

"Think what you want, but this is the reality."

Even if the other side wanted to destroy the entire Academy City in one strike at this time, it wouldn't matter.

Aleister remained unmoved, his expression unchanged, maintaining that chilling calm.

"But he was the one who told me about the previous timeline, and he was also the one who told me about the soul system and all of this."

"Although he could have resolved all of this himself, he seemed to have said something like, 'The course of events in the book will never lead to a dead end.'"

"books…?"

I completely...can't understand it.

Hatsune Miku and the Empress both looked at Aleister with strange expressions.

"oops."

It was at this time.

He raised his eyebrows slightly.

"However, something interesting has happened recently."

Followed by.

Under everyone's gaze.

Other figures flew in here.

Boom——! ! !

Someone who was directly knocked away.

She shot through the wall of the windowless building like a rocket.

"Waaaaah...!!"

"Vulnerable."

The one lying on the ground looked like a delicate young girl.

And those that appear directly inside windowless buildings.

Several figures.

"You expect me to do it at this level? Can't you do it yourselves?"

"Not at all. After all, it was a great being who commanded us. I think even you, as the God of the Demon Realm, probably understand what the consequences of resistance would be, right?"

"...I know I can't possibly beat that kind of monster with my abilities, but shutting up a nobody like you is a piece of cake, isn't it?"

"Okay, okay, I think we can cut down on the useless nonsense."

One person, two people, three people... They each stood at the entrance formed by the hole in front of them.

The three people looked like people I'd never seen before.

but.

Hatsune Miku's eyes narrowed as if they were pinholes upon seeing them.

"How could it be...you...?!"

Standing on the far left is a beautiful girl dressed in gorgeous purple and white clothes, with long purple hair, and surrounded by light butterflies.

Standing in the center was a young man with short silver hair, blue eyes, and a calm demeanor, with a smile on his lips.

The man on the far right is dressed in black, red, and gold clothing, with red and white hair, and a pair of blood-red eyes that exude an eerie atmosphere.

Butterfly, art, and the god of the demon realm.

"Why do you..."

"Oh dear, just as I expected, you do remember our story."

Butterfly slightly raised her finger and touched the corner of her mouth.

"Is it that boring soul system that's causing trouble? Ugh, how annoying. It's just a random thing that was indirectly created to facilitate the fusion of worlds, yet it's causing such a terrible problem at a time like this."

"That's why I told you a long time ago that we should get rid of these small fry with soul systems as soon as possible."

"Because there have always been two clueless guys causing trouble, let me think, their names are... Advisari and Weite, right?"
