[As soon as the scene shifted, everything was plunged into darkness. Then, a deep male voice filled with joy echoed—a voice that was extremely recognizable.]
["One thing I learned very early on… is that I was born with a empty in my heart."]
[The screen lit up. In a dilapidated auditorium, moonlight poured in as the simple yet timeworn sculpture of the Goddess's Embrace slowly turned black and white.]
["Stab—"]
[The perspective suddenly lifted upward. Purifying energy cascaded down from the sky like a waterfall. Beneath a cross on the rooftop, Kotomine Kirei held someone's head in one hand.]
["Crush him—invite the loser, old man!"]
[The camera showed Kotomine Kirei from the front. As the purifying energy surged down, his robes fluttered wildly and his hair danced in the wind.]
["Eternal life can only be granted after death."]
["Salvation is here—may the Lord have mercy!"]
[The light was overwhelming. Through the curtain of radiance, it could vaguely be seen that the old man had been completely purified, reduced to ashes.]
[The screen darkened once more, then slowly lit up again after a few seconds.]
[Click]
[A fully armed knight appeared. The helmet and visor of a Noble Phantasm fell away first, followed shortly by the gradual disarming of the armor on his body.]
[However, due to the camera angle, the knight's true face was never revealed.]
[A second later, the camera turned. Standing beside the knight was a man with three scars on his face, wearing sunglasses even in the dark. He spoke slowly:]
["I never would have expected that Mordred, the child of King Arthur… was actually a woman."]
[The camera snapped back. Mordred—her blond hair tied into a ponytail—clenched her teeth. Her eyes flashed with killing intent as she instantly swung her right hand, pointing her sword directly at her Master's throat.]
[At the same moment, her magical power surged, the air instantly compressed, producing an explosive sound as it was crushed!]
["If you call me a woman again… I won't be able to control myself next time."]
[Holding the great sword with both hands, Mordred spoke in a low, icy voice.]
["Do you understand?"]
[The voice slowly faded, and the screen gradually went dark.]
[Gareth]: @Mordred is so cool! I really wanted to talk to you earlier, but unfortunately I never had the chance.
[Tokiomi Tohsaka]: This… how is this possible? Could the Arthurian legend I read really be false?
[Kenneth]: It seems that the Saber-class Servant in this Holy Grail War is the legendary King Arthur.
Germany – Inside Einzbern Castle
"The true name of Saber has been exposed. What should we do, Kiritsugu?"
Irisviel looked at Emiya Kiritsugu with concern.
"There was another Saber in that video just now—wasn't that Mordred?"
Emiya Kiritsugu slowly shook his head.
"Iri, I don't know much about the earlier Holy Grail Wars. In the previous three wars, in which one was Mordred, the child of King Arthur, ever summoned as Saber?"
"Never," Irisviel answered firmly.
"In that case… it really is the future."
Kiritsugu's face grew solemn.
"Who exactly is behind that enormous screen? Not only can they communicate with Heroic Spirits on the Throne of Heroes, they can even show the future! And in that second scene—the Noble Phantasms of those two Heroic Spirits… That didn't look like a Holy Grail War at all."
Irisviel shook her head absentmindedly.
Similar conversations were unfolding all over the world.
On the other side, aboard a train bound for Guanbuzi City—
Shirou finally relaxed completely.
The video he had just shown included the future of the Singularity after humanity's incineration, the Fourth Holy Grail War from another parallel universe, and the present of this universe's timeline. He could even combine these images at will.
In other words—
He truly could display any video he wanted.
Even animated content that had never existed in his previous life could be generated directly and played based solely on a textual plot description.
Shirou made his decision immediately, and the next prepared video began to play once more.
Screens before every mage in the magic world—and every Heroic Spirit on the Throne of Heroes—lit up again.
[The video officially begins]
[As this line of text disappears, another title appears immediately afterward]
[Five Hundred Years of Perseverance]
[Beneath the title, a line of smaller text slowly appeared]
[Once upon a time, there was a man with grand ambitions.
However, as time passed, every aspect of the man gradually became distorted.
Whether it was his appearance, his soul, or his ambitions.]
[As the text slowly faded, the screen darkened once again. When it lit up, a snowfield appeared, goose-feather-like snow filling the sky.]
[On the snow walked a man with blue hair and red eyes. He moved briskly. When he looked up and saw a magnificent castle in the distance, an excited smile appeared on his face.]
[Soon, the man arrived at the castle. An android maid emerged to question him about his identity.]
["My name is Magiri Zolgen. I am here to visit the Lady of Winter."]
[After reporting to the android maid, Magiri Zolgen was successfully admitted into the castle and met the Saint of Winter, Justeaze, as he had wished.]
[After some discussion, Magiri Zolgen looked at the Saint of Winter and made his request:]
["Magic is a great power in this world. I wish to use that power to eradicate all evil—evil itself, and human evil."]
[The Saint of Winter, Justeaze, looked at Magiri Zolgen but did not immediately agree. Instead, after a few polite exchanges, she approached Ahadion.]
["Lady Saint, I believe we can agree. As a man with nearly three hundred years of experience in magecraft, he will certainly contribute to the reproduction of the Third Magic. Since he has proposed using you, Lady Saint, as the core substrate for a magical furnace plan, we may as well make use of him."]
—Ahadion said.
[In the image, the Saint of Winter slowly nodded in agreement.]
[Matou Zōken]: Ahahahaha!
[Tokiomi Tohsaka]: !!! The Holy Grail that people fought over in the Holy Grail War… was never a wish-granting machine? It was merely a tool to reproduce the Einzbern family's Third Magic?! No—no—that can't be right!
[Ahadion]: H-how is this possible?! Two hundred years have passed—how could anyone know this?!
[Kischur Zelretch Schweinorg]: How fascinating. I noticed that millions of worldlines began collapsing six months ago. Even now, six months later, I still hadn't understood why. So this is how it is.
[Tohsaka Nagato]: @Zelretch, teacher!!!
[Tokiomi Tohsaka]: @Tohsaka Nagato, Ancestor! You can see these images too?!
For a moment, nearly every mage in the magic world watching the screen was left in shock.
This screen not only revealed long-buried secrets of the mage world—it even allowed the dead to witness these images… and speak!
P.S.
For those who still haven't understood, I would only change the stories based on Shirou from the Fate multiverse, not on the other characters but only on MC and those around him, not already defined characters.
