I'm doing a crossover anime/manga project, and I'm creating a new kind of "Moonlight&

By July of this year, a total of 324 files had been completed, with clear records of people, places, and times. Even the names of the investigation team leaders, specific members, and their affiliated units were clearly recorded.

Moreover, both Hikigaya and Ayanokoji had some recollection of the events mentioned above.

For example, the Saitama Titan incident last year, which was witnessed by eyewitnesses and even had photographs.

It didn't cause much of a stir; instead, it was considered to be AI-generated, and people marveled at how fast AI technology is advancing.

And the number one [stand-in] goes without saying.

Kiyotaka Ayanokoji looked into it afterward, and even now, thinking about it still makes him break out in a cold sweat.

The kind of despair, like the Grim Reaper coming, where fate is about to kill you, is suffocating just to imagine it.

Kiyotaka Ayanokouji took a deep breath, picked up the file, and calmly asked, "So, teacher, are those things from other worlds?"

Is this the crisis their world is facing?

"It doesn't count."

"It doesn't count?"

Ayanokouji's pupils contracted, and as if remembering something, he blurted out, "A Lostbelt?!"

Rosser smiled.

Hachiman also realized what was happening.

Among the more than 300 files, the monster that claimed to be a ghoul clearly came from Earth, or even from Tokyo.

Tokyo in a parallel world.

Isn't this Lostbelt?

From a certain point in time, a divergence occurred with pan-human history, leading to different dead ends in different worlds!

The thought sent chills down his spine.

If you were in a dead end in a world, what would you do if you saw a perfectly good world?

Ayanokouji also thought of this, and the two looked at each other, both seeing the fear in each other's eyes.

Yes!

Compared to the life-or-death war between two worlds, or even multiple worlds, what are mere evil spirits?

Rother sighed, "Since the Age of Gods, humanity has faced endless challenges from evil, but we have driven the gods from their thrones, banished fantasy to the inner seas of stars, and driven vampires to hide in coffins for millennia. But there is one thing we can never defeat, and that is..."

"Ourselves..."

Hikigaya's voice was dry.

It's not just wars between humans; it's a world heading towards its end.

If their worlds intersect, all the sources of disaster will converge and breed together a treacherous force.

In this situation, what's the point of living?

He suddenly thought of the game's opening sequence.

Extinct stars, Lostbelt debris floating in the void, a desolate land...

Holy crap, could that really be the future of their world?

Volume 1: Chapter 30 What does it mean to save the world using the Holy Grail War?!

Both of them trembled, shuddering at the thought of this terrifying possibility.

"Yes, that's one possibility for the future."

Rosser said calmly, "But time cannot be reversed, the past cannot be changed, and the future is uncertain. What we can observe is only a part of it, and it is only one possibility of the future."

His words of comfort had absolutely no effect.

The same thought simultaneously crossed the minds of Hachiman Hikigaya and Kiyotaka Ayanokoji: This might not be the most likely scenario.

If it's just one possibility, is it really necessary to go to such lengths?

"Allah, Allah~"

Rosser comforted him, "We already have a plan for this. As long as we reignite the Holy Grail War in the modern era and wield the Omnipotent Cauldron, we can rewrite everything."

Holy Grail War?

Hikigaya and Ayanokouji's minds were filled with images of all sorts of people and gods, disillusioned with humanity, seeking to destroy the world with the Holy Grail...

Cheating!

What do you mean by using the Holy Grail War to save the world?!

Is that something that can save the world? Are you sure it won't just die out immediately after it was supposed to live for hundreds of years?

The two almost blurted out their complaints.

I can't relax at all!

We think the Holy Grail War is way scarier than ghost stories!

“Mr. Rosser..…”

Hachiman forced a smile: "Isn't holding a Holy Grail War a bit too much? I think we should trust humanity. This is a small matter; there's no need for the Holy Grail to interfere..."

Even Ayanokouji, who usually prefers to stay out of things, nodded repeatedly this time: "That's right, teacher, I don't think it's necessary for the Holy Grail to intervene at all!"

Let's wait until he's in his peaceful old age, at least.

After he dies, there's no need to worry about the raging flood.

"Oh?"

Rosser gave a strange smile, something unknown swirling in his dark eyes: "Do you really think your daily lives exist for some other reason?"

Hachiman swallowed hard. "Mr. Rosser, you mean..."

Ayanokouji Kiyotaka's pupils contracted: "Sensei, do you mean our daily lives are also because of the Holy Grail?"

Rother chuckled and looked at Hachiman: "Hey Hachiman, why do you think it's necessary for you to see the evil spirit, and for the evil spirit to confirm that you can see it, before it can attack you? Do you think this happens naturally?"

of course not!

It is filled with traces of artificial design.

Ayanokouji murmured, "Yes, I should have realized it sooner; it couldn't possibly have happened naturally..."

Hachiman was also at a loss.

So, the reason they can maintain a normal life is simply because that terrifying world has been isolated and confined to another dimension?

Rosser's smile vanished in an instant.

It certainly didn't happen naturally.

Because even evil spirits are not born naturally, this world was originally just an "ordinary" technological world.

The anomalies arose because the shattered source matter fell into this world.

In the past, people probably didn't even have souls; death was simply complete annihilation.

Needless to say, evil spirits are most likely born from the authority of "life" or "soul" derived from the great being's "creationism".

The order that isolates evil spirits should be the result of evolution and order in the theory of evolution of the great.

Evil spirits, which are not naturally evolved, will naturally be excluded from the mortal world.

But that doesn't prevent Ross from understanding cause and effect...

"In the distant age of gods, humans and gods lived together. Mystery was not hidden from the world, and the boundary between the living and the dead was not clear."

Even after Gilgamesh bid farewell to the gods in the West and Zhuanxu severed the connection between heaven and earth in the East.

It draws a line between the living and the dead, separating life and death.

Although the living can still communicate with the souls of the dead in the underworld through rituals such as sacrifices.

But humans are never satisfied...

Rosser sighed.

The simple description captivated the two high school students.

Both boys were the type who enjoyed reading all sorts of miscellaneous books, and they had both heard of Gilgamesh and Zhuanxu, who had conquered the world.

But then Rother's sigh made their hearts skip a beat.

Don't they know what kind of idiots humans are?

Desire is the driving force behind humanity's progress and its rise to the pinnacle of planetary history, but it is also the key to destruction...

The rest is self-evident; they can guess what happened.

Eighty percent of the time, someone with the makings of a protagonist shouts, "Come back, my love!" causing the boundary between life and death to be broken, and all the ghosts to be unleashed!

and many more.....

Kiyotaka Ayanokouji suddenly looked up: "Teacher, could it be that the Japanese legend of the 'Night Parade of One Hundred Demons' and the Chinese legend of the gates of hell opening on the seventh day of the seventh lunar month are...?"

"good."

Rosser nodded slowly: "That terrible disaster caused an unprecedented tragedy in human history..."

Even though the source is dead, some are born to fulfill their destiny, inheriting the prophecy of the Golden Blade. They obtain the Northern Star Heavenly Wolf Blade, a divine weapon known as a divine weapon in the East due to its different magical foundation. Leading ten thousand ghosts out of their cages, they sweep across the east and west, engulfing the world and causing the deaths and injuries of hundreds of millions…

"Genghis Khan...?"

Ayanokouji and Hikigaya exchanged a glance and read out this very famous title.

The prophecy of the golden knife is a prophecy originating from ancient China.

It means "the Liu family will prosper", which is recorded in the Book of Southern Qi.

When Genghis Khan and the leader of the Kereit tribe became sworn brothers, they exchanged gifts of golden knives, symbolizing their eternal unity and willingness to share joys and sorrows.

The key point is that, according to Ayanokoji, Genghis Khan's father and sons all tested positive for direct genes from Liu Bang, the founder of the Han Dynasty.

That actually matches up!

Moreover, the divine weapon and treasure, the Northern Star Wolf Blade...

"The so-called divine weapons and treasures are the embodiment of historical legends, such as the Fish Intestine Sword, the Giant Sword, and the Red Sky Sword of Emperor Gaozu of Han in the East, and the legendary sword Durandal in Europe, the Sword in the Stone, and the Mountain-Slaying Sword, etc."

A Noble Phantasm is both a divine weapon and a destiny... To accept a Noble Phantasm is to accept one's destiny.

Rosser said calmly.

Even though the core of the treasure he created was source matter, it still needed to absorb ancient legends to take shape, and the legends themselves were a kind of destiny.

Not to mention that the source material itself is a fragment torn apart by the aggregation of the three great beings.

Every part of it has been tainted by fatalism.

Including him, but fortunately he is now the pollution itself, so it doesn't matter.

"destiny?"

It was a familiar word, yet it sent chills down their spines.

They had a vague feeling that it was not a blessing at all, but rather a curse of despair.

"Yes, fate..."

Roser chuckled: "Holding the imperial mandate accumulated over a thousand years, Genghis Khan swept across the world, but his southward advance stalled. So let's leave the main force behind and train troops to the west."

They destroyed the ancient hegemon Persia, trampled grasslands, tore apart civilizations, conquered peoples, and uprooted ancient magic families and societies.

They made everyone, whether in the Middle East or Europe, wail under their iron heel.
