I Forge the Holy Grail War, Shocking the World

In an instant.

The Life-Killing Stone transformed into a streak of light and merged into his wrist, forming three vivid red Command Spells.

The young man curiously touched his wrist.

He could feel a wondrous power residing within him, ready to be unleashed at any moment.

However, something seemed to be missing, preventing him from summoning a Servant, a persistent frustration.

Luo Shu knew very well that this was because the Life-Killing Stone was limited to summoning Heroic Spirits from the Fate series. He hadn't yet created a pseudo-Hall of Heroes, and these three Command Spells were like boundless water, making it nearly impossible to summon a Heroic Spirit.

Meanwhile.

Tokyo, Hokkaido, Osaka... Life-Killing Stones scattered across the island nation began to glow, trembling strangely. It took several minutes before they returned to stillness.

"..."

In various locations, several holders of the stones furrowed their brows in unison, unsure of what had happened.

Concerned about this precious treasure, they wanted to ascertain the root of the problem. They each felt their blood-red jade beads, observing them for a long time, but found nothing unusual. The Life-Killing Stones were as before, easily controlled.

Ultimately, they dismissed it as the Life-Killing Stones acting up.

"Phew, everything's resolved~"

"It's time to create the Sky Screen and play the full version of Fate/staynight!"

At Happiness Villa, the young man with the feather robe was lost in thought, his smile fading.

The Divine Authority Jade began to be consumed frantically, quickly running out.

He clenched his right fist, which was brimming with a mysterious and profound aura.

Then.

He spread his fair palm, facing the sky, and a mysterious golden light source flew out.

There seemed to be an inexplicable pull from the heavens.

After ascending, the golden light source became increasingly tiny, soon soaring past the troposphere, ionosphere, exosphere... until it broke through the atmosphere, where it began to spread rapidly. Its vast radiance instantly enveloped both the Northern and Southern hemispheres!

A peculiar fluctuation emanated from the heavens, profound and mysterious.

At this moment, across the entire world.

In every country and for every ethnicity.

Regardless of age or gender.

Everyone looked up in astonishment.

Under the awe-struck gazes of countless people, sacred light enveloped the great earth.

The Sky Screen... had descended!

21. The movements of various forces, the beginning will be met with thunderous applause!

In the seas of clouds above Japan, where layered peaks resembled an ocean floating in the sky.

At the center of the mountains, Shuten-doji, the "Demon King" who proclaimed herself the ruler of Ooe Mountain, was leisurely drinking. Suddenly, she sensed the commotion in the sky. Her slender, fair feet swayed lightly, and she became intrigued.

The fine wine dripped onto her fair skin, but she paid it no mind, playfully remarking to her companion.

"What a commotion, have the humans invented some new technology?"

"Ibaraki, what do they call this again...?"

"Holographic projection?"

Beside her, the busty Ibaraki-doji scratched her head, not entirely certain.

Shuten-doji lightly patted her best friend's shoulder, glanced at the Sky Screen, her beautiful smile filled with anticipation.

"As expected of a favored race, they always manage to put on a good show when we're bored."

"Let's just watch quietly."

In Horiuchi Town, Kobe City, within a solemn shrine adorned with paulownia crests.

The ancient divine sword named "Muramasa," which had selflessly protected this land for hundreds of years, was now vibrating wildly on its stone pedestal. As if sensing an unprecedented danger, its blade trembled, instinctively wanting to fly out.

A wisp of green smoke slowly rose from the blade, transforming into a green-haired loli dressed in a kimono.

She tried her best to put on a dignified expression, scanned her surroundings, and then shouted at them.

"What kind of malevolent spirit dares to act so presumptuously before me?"

Silence reigned within the shrine.

After a long while.

Sensing that the anomaly originated from the heavens, the ghostly loli breathed a sigh of relief.

As the administrator of Muramasa, she felt her life threatened for the first time. Previously, she was the one who crushed the heads of malevolent spirits.

"That's terrifying!"

But...

"What on earth is that thing?"

Gazing at the Sky Screen that enveloped the world, Muramasa-chan fell into unprecedented confusion.

Itomachi, Gifu Prefecture, the solemn and ancient Miyamizu Shrine.

A girl in a sailor uniform, somewhat airheaded, stared blankly at the sky.

Has the outside world become this advanced?

Fumizuki Academy.

"Hideyoshi, hurry up and get out of the Hideyoshi Bath, something big has happened!"

With a magnificent exclamation, the stunning "girl" walked out of the bathroom in confusion.

"Could this be a sign that I'm about to cross over to another world and become a winner in life?!"

On a rural highway, Kazuma Sato, a "hikikomori," exclaimed.

The same scene unfolded across various locations.

Some worried, some feared, some were confused, and some didn't care...

Even more, lowly office workers became excited, raising their arms and shouting for the alien overlords to come and destroy the world!

Regardless, this shocking sight had long been imprinted in the hearts of countless people.

Amidst the myriad of human conditions, the brilliance of the Sky Screen flowed and changed, displaying lines of dark text that explained the current situation.

[The Great Thousand Worlds are full of wonders. Do you ever wonder if there's another you in the world, living a life completely different from yours, so spectacular that it makes you envious?]

[The same person, yet with diametrically opposed moral bottom lines?]

[If history took a different turn, would those historical figures still exist?]

[Now, we will begin exposing classic events that have occurred in parallel worlds.]

["Fate/staynight," play!]

Shiritsu Toyonozaki Academy.

A certain blonde girl with twin tails stared at the Sky Screen in shock, with two options appearing in her field of vision.

—[Normal Mode]!

—[Motion Mode]!

What the heck is this?!

Eriri Spencer Sawamura felt a bit nervous.

She had just curiously glanced at the Sky Screen, and this was the result.

The Sky Screen didn't seem to interfere with her choice; the options would disappear if she looked away.

But she was really curious right now!

Were the stories of parallel worlds real?

And Fate/staynight, wasn't that the PV from the Observer Net?

Was all of this some big shot's black technology, or an alien invasion?

Maybe she should watch it first...

Everyone else was watching, so it should be fine!

Normal Mode, based on the literal meaning, should be a normal viewing mode?

Then what was Motion Mode?

Could it be a mode with a stronger sense of immersion?

"Maybe Motion Mode?"

Eriri hesitated for a moment, but her curiosity quickly overcame her reason.

The instant she mentally selected [Motion Mode], the massive Sky Screen seemed to transform into a black hole.

A terrifying pulling force rose above her body, as if trying to suck out her soul, and the girl immediately panicked.

No...

It wasn't an illusion.

Eriri stared in shock at the husk below her, feeling an incredible lightness spread through her body.

My soul was actually sucked away, dammit!!

She was dazed for a moment, then her vision went black and she lost consciousness.

"Make way, make way, the young lady has arrived!"

"Can we still go back to Earth?"

"This floating, soaring feeling... Madoka, something feels really strange."

"Madoka, where are you?"

"Is this a trap by the Holy Controller? The Evil Eye of the Wicked King will not yield!"

"I'm so curious~."

"What a coincidence, Shikimori, you're here too?"

"Eh, Okami!"

A cacophony of voices echoed in her ears.

Eriri awoke, and in her panic, realized she had arrived in a pitch-black world.

She had become a sort of ghost, an unseen observer.

There were many other ghosts like her around.

Here, she also saw a familiar woman... Utaha Kasumigaoka!

And, the flat-chested black-haired woman she'd seen in the Fate/staynight PV, a dual-wielding Heroic Spirit with clear justice in her eyes. However, the feeling she got from this one wasn't as resolute as in the video.
