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

The people of Earth finally realized that the situation seemed to be spreading to them...

.......

"Don't worry, is there somewhere else you're falling into the warp?"

Rosser reassured him, "Don't worry, as long as it's not worse than this world, there are at least tens of thousands of years left."

Look how many years has this little bit of sauce struggled? It tried again and again, trying different methods. Now, tens of thousands of years have passed, and it's only reached the end of the world, hasn't it? And even though it's said to have reached the end, theoretically, there are still more than ten years left.

"...Hmm, why do you look like your world is even more exaggerated than this one?"

"This is even more outrageous than this—!!"

Deep within dimensions.

The chaebols like Shinomiya Hiromitsu and Suzuki Ayako, along with high-ranking officials from various countries such as Trump, almost screamed out loud.

Don't scare me like that! You'll scare me to death! Tell me you're joking!

But it was clearly not a joke.

In theory, their world is the Yellow Spring Dimension, the precursor to the unborn subspace, and even the entire solar system is inside the belly of a giant evil spirit.

Rother's statement is an understatement...

"So, this time, after killing so many people, she really did it to save the world?!"

Kurumi Tokisaki said in a hoarse voice.

She suddenly couldn't understand who was truly righteous. People had tried for tens of thousands of years to save the world, and as for the slaughter...

To be honest, she killed quite a few people, and she could guess what they were thinking. Her repeated attempts to reverse time in vain were probably because the people she killed would also come back to life.

But if it happens too often, the appreciation for life will fade.

"Of course, it was probably the umpteenth time before, anyway, after the world was falling into the subspace to the point of almost touching it, she found a book outside the world."

"The Seven Secret Chapters of the Mysterious Monarch!"

Kurumi Tokisaki uttered the name of that terrifying grimoire, taking a deep breath: "So she wants to ascend to become an Outer God to save the world?"

That's a good idea. All the problems stem from the parties' lack of ability. If...

"Who did you listen to?"

Rother asked curiously, "As for Outer Gods, she arrived the moment she got the book. And you think too highly of Outer Gods. Unless they are formidable figures like the One Who Unifies All Things, Outer Gods are meaningless in themselves."

Kurumi Tokisaki was taken aback. Had they all guessed wrong?

"The purpose of Yimoduo is merely to replace all of humanity and even the planet with a perfectly intact world, using other worlds as scapegoats."

Rother shrugged: "That was indeed an ascension ceremony, but not her ascension. It was the ascension of the planet, and not only ascension but also displacement, replacing the souls of the planet and humanity with those of other safe universes, and thoroughly discussing the subspace."

Ultimately, only planets are humanity's true home. As for the solar system and other places, let's just give up on them.

I've calculated it; the success rate isn't high, but the fact that there's even a success rate is incredible in itself.

Even Rother was amazed by the idea.

Although the subspace is not yet fully formed, the Yellow Springs dimension has the largest piece of source matter for support, as well as many other sources of source matter. Under such circumstances, how can a practical technology for escape be conceived?

Therefore, experiences have a truly significant impact on shaping a person!

"..."

Kurumi Tokisaki opened her mouth, her thoughts somewhat muddled.

To say that Matou Kurumi went too far, making an innocent world die in its place, is immoral?

She couldn't say it.

Seemingly sensing his thoughts, Rosser comforted him, "Don't worry, there are hardly any humans left in the world that my sister chose."

Rosser gave a thumbs up: "Trading dozens of people for over eight billion people is an absolute bargain."

Kurumi Tokisaki was already numb; she instantly guessed which world it was.

"Anyway, Ritsuka-kun probably can't save the world. The final boss is completely unsolvable. He won't die unless the temple is destroyed, and the temple won't be destroyed unless he dies. Tsk."

"Isn't there any way to survive in the Warp? Like what you said about all of humanity becoming Servants, and so on..."

Kurumi Tokisaki stared wide-eyed, incredulously asking, "You're not trying to save the world too, are you?"

"Well, it's my own fault, so I have to find a way to fix it, right? But unfortunately, although my method could succeed, it was rejected by humans~"

Rosser said innocently, "After all, that's not the proper source. If you go in, you'll become an entropy demon, a demon of information entropy throughout. I only know one that can survive in the warp."

Kurumi Tokisaki took a deep breath and stared blankly at Rosser: "Lord of Cinder! That was indeed your true past, but now it seems... you failed too?"

"Yes."

A gentle night breeze swept by.

The boy nodded calmly: "We failed."

After all, failure is the norm on the path one chooses.

Now it means that humanity in this world is acting like a human being. In the very beginning, those chaotic subconscious souls were the most direct reflection of evil.

He started over again and again, beating himself repeatedly, until he finally became human again.

But at the beginning, he was mostly beaten up. He recovered from failure, depression, despair, and numbness time and time again. His personality would change to some extent with each cycle, after all, a person is the sum of their experiences.

In his past lives, the Lord of Cinder was one of the most glorious, single-handedly shouldering the world's burdens. However, when he encountered a time-space turbulence and was delayed, by the time he returned from hunting souls, the world had already collapsed, and everything he had protected for thousands of years had been buried long ago.

After all, the spiritual universe is also a universe, and time is meaningless between worlds; a moment can be thousands or tens of thousands of years.

That's what it means to entrust the fate of the world to one person—you can't afford to take even the slightest risk.

So he sat alone in the pseudo-subspace for over ten thousand years in that world, until his pre-set alarm rang, pulling him out of the dream...

“…”

Kurumi Tokisaki didn't know what to say. The boy just looked calmly into the distance, but seemed to belong to another world, with a quiet and aloofness that seemed detached from the world.

She still has her hometown to return to, but everything the other person protected has disappeared, fading away little by little in the passage of time.

At this time.

Suddenly, a red light appeared in the city center, growing brighter and brighter until it illuminated half the night sky. Then the earth trembled, and a gale swept through the entire city of Fuyuki.

"Has the final battle of Heroic Spirits begun? Next, Sister-chan will probably put pressure on them, forcing the people of Ledy to send more materials called Heroic Spirits, right?"

The boy immediately regained his frivolous demeanor and looked into the distance with great interest: "After all, there are no humans left in that world. It's not enough. At least a three-digit number of Heroic Spirits would be needed to manifest, along with the Composite Holy Grail, to barely manage to move a thousand pounds with a few ounces and replace all eight billion souls there, right?"

"Impossible, Chaldea simply doesn't have that much magic power stored up..."

Halfway through her sentence, Kurumi Tokisaki, who had subconsciously denied it, paused in surprise.

She remembered that Leonardo da Vinci had not yet returned the magic gem, which possessed planetary-level magic power, to the boy before her.

"I gave them a chance."

The boy spoke calmly, his azure eyes reflecting the firelight that spread through the city with the tremors, giving him an air of aloofness as if he were detached from the world.

"But they seem to be used to using petty tricks."

more than.

Kurumi Tokisaki pursed her lips and said softly, "Did you deliberately remind them back then?"

The so-called interest issue was just a reminder, but Chaldea probably planned to keep the magic crystals for emergencies. If they won, they could pay them back slowly, but if they died, there would be no chance to exchange them.

Why not keep it for now, since you can't afford the 30% interest anyway?

Why do people continue trying to gain small advantages even though they know it will lead to problems?

Gazing at the dazzling aurora borealis shimmering and illuminating the night sky, the young man sighed softly:

"You reap what you sow."

.....

Civic Center.

The shattered earth, the burning trees, and the haphazardly laid, resilient bodies covered in thick scales.

"Dragon Fang Soldiers, all of them are Dragon Fang Soldiers, how many are there?"

Hachiman coughed up blood, tried to stand up, but collapsed helplessly into a pool of blood.

In front.

Zi~~

Kazuma's gaze was icy, and arcs of electricity burst forth from his entire body, swirling and winding.

suddenly.

Purple arcs of light shone, transforming into streaks of sword-like light that leaped and crisscrossed in the darkness.

It was as if the air itself blurred for a moment.

Kazuma's figure slowly became clear, appearing a hundred meters away. Two sharp blades swirled in his hands for a moment before gradually dissipating...

Behind.

The two tall and imposing dragon tooth soldiers, frozen in time, emitted a burst of intense white light from their eye sockets, which gradually weakened over time, and the two massive dragon tooth soldiers slowly collapsed to the ground.

"You've gotten even stronger, Kazuma."

Lying in a pool of blood, Hachiman tugged at his gruesome wound and smiled.

"You'd better stop laughing. You've lost an eye, your nose was wiped off, and three of your limbs are missing. It's pretty scary."

Kazuma, still complaining, staggered back and plopped down next to Hachiman, saying shamelessly, "If you're really that strong, you should be facing the King of Heroes with Lancelot, not dealing with these grunts here."

The movement aggravated his wound, causing him to grimace. "I never thought we'd be facing monsters like the Dragon Fang Soldiers."

"indeed."

Ayanokouji, who had stood up to change shifts with his sword drawn, nodded with a slight gleam in his eyes.

Those were Dragon Tooth Soldiers, the psychological trauma and nightmare of countless Earthlings.

Absolutely unmatched in strength, with overwhelming oppressive power; without nuclear weapons, two hundred Dragon Tooth soldiers are enough to annihilate a modern superpower.

However, after the initial excitement, they quickly quieted down.

Until Hachiman said softly, "I miss it more and more..."

Although they didn't say it explicitly, they, including the Earthlings from the depths of the dimension, clearly understood what they were talking about.

They look very similar.

It was like that desolate world they had once explored, also named Fuyuki, a world also ravaged by Dragon Fang Soldiers.

"The Dragon Fang Soldiers were summoned by the corrupted Servant Caster Medea, but what about the Sword Demon?"

Hachiman sighed.

Is it really the future...? Have they failed...?

No time to think.

“Tatata..…”

As the earth trembled, a dense, muffled sound of footsteps echoed.

A vast, dark mass of Dragon Fang soldiers emerged from between the buildings, silently pressing down like towering steel mountains, stretching as far as the eye could see, far exceeding the number depicted in the game Fuyuki.

Everyone's face froze.

This quantity.....

Blood streamed down his forehead. Kazuma, leaning on the railing, stood up: "Looks like I'm going to die here, Ayanokouji."

"To die here, I'm truly unwilling..."

Ayanokouji pursed her lips, her hand holding the sword trembling slightly, but she did not run away.

Why? Would someone like him protect others?

"Don't hesitate, because there's no turning back. Either you win, or you'll be buried with this world!"

Squeezing out all the life force within his body to form a boundless magical power, he and Zhen constructed a longbow, which roared amidst a burst of purple light:

"Monsters, I am the First Investigator and the Great Lord under the command of Lostbelt King Rosser. Listen up, stop in front of me, demons are forbidden."
