Chapter 20. Command Spell Resonance System, Celestial Curtain Appears, Shocking the World!
Chiba City, Happiness manor.
The long night dragged on, and the horizon gradually revealed a faint light.
In the bedroom, a young man wearing a white feathered cloak was scratching his head in frustration, fiddling with a round, blood-colored gem in his hand — it was the Killing Stone.
"Tch, what the hell am I supposed to do with this thing?"
After safely escorting Kagome back to Higurashi Shrine, Raku Sou had returned to his rental apartment.
After the battle in the Mt. Nokogiri forest, he had used a self-realized, one-time skill — [Hiken – Tsubame Gaeshi] — to effortlessly slay the evil spirit threatening the city. But as a result, he had burned through around seven hundred Divine Authority Jades.
That was still thanks to the recent release of the Fate/stay night PV — many people now had a vivid impression of the Tsubame Gaeshi technique used by Sasaki Kojirou.
Otherwise, he would've had to burn at least three hundred more Divine Authority Jades.
Although the cost was enormous, over the course of a single night, more and more people around the world had joined the Observer Network, becoming loyal fans of Fate/stay night, and in their reverence and worship, they contributed a significant number of Divine Authority Jades.
At this moment, the total number of Divine Authority Jades he had accumulated had reached 7256.14!
And with the current snowballing momentum, the growth rate was accelerating.
It had now reached the threshold required to create the Celestial Curtain.(Note: Previously translated as "Celestial Screen," I changed it to sound better.)
However, he still needed to figure out how to deal with the Killing Stone first.
Using it directly was definitely out of the question — the Killing Stone carried extremely strong demonic properties, and would silently twist him into a mad murderer.
While it was technically possible to eliminate the side effects using Divine Authority Jades, purging a treasure that had entered Tier 4 territory would require at least tens of thousands — maybe even a hundred thousand — Divine Authority Jades.
That would be absurdly wasteful. Not to mention, he was still dirt-poor at the moment.
The young man crossed his arms in front of his chest, falling deep into thought. Then, he suddenly opened his mouth and asked the silver ripple:
"Void, if I wanted to use the Killing Stone as energy to summon a Heroic Spirit from the Fate series, would that be possible?"
"Bzzzzzt... (Calculating...)"
On the left side of his vision, the silver ripple trembled with excitement and quickly gave an answer:
It's possible!
The fundamental nature of the Killing Stone was a condensed mass of energy.
It inherently possessed the duality of yin and yang — containing both the deep resentment and hatred at the moment of the Nine-Tailed Fox's death, and a store of incredibly pure, harmless energy.
This was also the reason why those who possessed the Killing Stone were prone to madness.
When one uses the power of an evil dragon, the reverse scales will also grow from their own neck.
The two sides blended together, nearly indistinguishable and almost impossible to separate.
To completely extract the killing aura from the energy was extremely difficult.
But Void had a workaround!
Raku Sou could choose to spend 2000 Divine Authority Jades to implant Heroic Spirit Mode into the Killing Stone!
After a successful implantation, he could then use the killing aura within to summon a Heroic Spirit. When the Heroic Spirit fell in battle, the killing aura would dissipate into the world, leaving behind pure energy that could be reclaimed — and used to upgrade himself.
At the lowest cost, he could obtain a bodyguard on par with Tier 4.
And once the bodyguard died, they'd even drop loot!
How amazing!
It really was killing two birds with one stone.
The corners of Raku Sou's mouth lifted slightly, a smile as gentle as the spring breeze appearing on his face.
But right after that, he seemed to recall something — once again falling into deep thought.
Wait a minute…
Everything was already prepared. He was ready to use the Celestial Curtain to publicly launch a "Holy Grail War of the Parallel World"…
Then why not go a step further — and become the mastermind himself, orchestrating a Holy Grail War right here in the real world?
He could shake the entire world, while at the same time increasing global belief and trust in the Fate series!
Under normal circumstances, creating seven Servants in the real world would cost at least several million Divine Authority Jades.
But now, it was different.
He could play for free!
Taking advantage of the rich resources available in reality, he could host a grand Holy Grail War.
Raku Sou might not have millions of Divine Authority Jades, but other people had Killing Stones!
Recalling Ga-Rei: Zero, there were a total of nine Killing Stones scattered across the world.
There were five individuals who had ever possessed a Killing Stone.
They were: Kagura's father, Kagura, Mikado Tooru, Isayama Yomi's sister, and Yomi herself.
Although Kagura and her father shared one stone, Mikado had his own, and Yomi and her sister shared another — throughout the entire anime, only three Killing Stones ever appeared…
But in theory, the real world could potentially summon up to nine Heroic Spirits.
Whoever possessed a Killing Stone could summon a Heroic Spirit.
Once these Heroic Spirits descended one after another and began fighting to the death on the grand stage of the real world, it would absolutely shake the world to its core!
As for Raku Sou himself, he only needed to calmly play the role of the mastermind behind the scenes, sitting securely on high and reaping all the rewards.
Every time a Servant fell, he would appear to recover the purified energy.
He'd be earning Divine Authority Jades and gathering countless resources — a total win.
Raku Sou rubbed his chin with his index finger, smiling softly as the corner of his mouth unconsciously curved upward.
But — the prerequisite for all of this to happen was:
He had to use the Killing Stone in his hand to resonate with the other stones scattered across the world.
He quietly asked:
"Void, while implanting Heroic Spirit Mode into my Killing Stone, can you simultaneously establish a resonance system, so that the other Killing Stones will also be affected?"
"Bzzzzt.... (Possible, but it will cost an additional two hundred Divine Authority Jades)."
The silver ripple trembled slightly, obedient and calm.
"Alright then, do it just like that," Raku Sou nodded in satisfaction.
Upon receiving the command, Void began consuming Divine Authority Jades. A brilliance invisible to ordinary people enveloped the blood-colored gem, gradually seeping into its interior, beginning the process of structural transformation — mystical auras continuously radiated outward.
At that moment—
The Killing Stone turned into a stream of light and entered his wrist, forming three red Command Seals.
The young man curiously touched his own hand.
He could feel — a mysterious power now resided within his body, ready to be summoned at any moment.
But it still felt like something was missing, like a bone stuck in his throat — he couldn't summon a Servant no matter what.
Raku Sou understood very clearly why — because the Killing Stone had been restricted to only summon Heroic Spirits from the Fate series, and he himself had yet to construct a Pseudo Throne of Heroes. So, these three Command Seals were like water in a desert — practically useless for summoning any Heroic Spirit.
Meanwhile—
Tokyo, Hokkaido, Osaka... The other Killing Stones scattered across Japan simultaneously lit up, vibrating in strange rhythms, before gradually settling down minutes later.
"..."
Across different locations, all those who possessed a Killing Stone furrowed their brows, unable to figure out what had just happened.
Because it concerned their own treasured artifact, they each carefully examined their blood-colored gem, scrutinizing it for half a day—
But they discovered nothing unusual.The Killing Stone still operated as before, responding like an extension of their own limbs.
Viên đá giết chóc vẫn hoạt động như trước, phản ứng như một phần mở rộng của tứ chi của chính bọn họ.
In the end, they just chalked it up to the Killing Stone acting up again.
"Haaaah, everything's all taken care of~"
"Now it's time to launch the Celestial Curtain and broadcast the full version of Fate/stay night!"
At Happiness Manor, the white-coated young man spaced out in a serene trance, the smile on his face gradually fading.
Divine Authority Jades began burning at an alarming rate, and were soon nearly exhausted.
He clenched his right fist tightly — it pulsed with mystical and divine energy.
Then—
He opened his palm, pointed straight toward the sky, and released a ray of mysterious golden light.
It was as if some invisible force from the heavens had received the signal.
As it soared upward, the beam narrowed, piercing through the troposphere, ionosphere, and diffusion layer — until it finally broke through the atmosphere. Only then did it suddenly expand, erupting violently, and within the blink of an eye, the blinding light enveloped the entire Northern and Southern Hemispheres!
A strange vibration resonated from the very ends of the firmament — dreamlike and otherworldly.
At that moment — the entire world.
Nations. Ethnicities.
Men, women. Young and old.
Everyone looked up—without even knowing why.
And under the astonished gazes of billions, a sacred halo enveloped the mortal realm.
The Celestial Curtain — had descended!
