Ding..Dong
A sudden mechanical sound echoed inside Shirou's mind.
His eyelids twitched instinctively.
As a veteran otaku from his previous life, he immediately understood what that sound represented.
A system…?
But a video sharing system?
Before he could think any further, an overwhelming torrent of information flooded his consciousness. Data, functions, operational rules—everything was forcefully engraved into his mind, leaving no room for resistance.
Several seconds passed.
Shirou slowly exhaled.
He understood it now.
Simply put, the system granted him unrestricted access to all memories from his previous life, including complete and unfiltered knowledge of the Fate/Type Moon universe. His role was just as straightforward: compile that knowledge into videos—and share them.
Any video he uploaded could be viewed by anyone.
The living.
The dead.
Even Heroic Spirits who had already been reduced to records and stored within the Throne of Heroes.
As long as a shared video altered an established fate, Shirou would be given the chance to intervene in the flow of destiny itself. The greater the deviation caused by the content, the more the future of the timeline could be reshaped—at least, according to his understanding.
If a video attracted attention and sparked discussion, the interference would deepen, allowing the timeline to be reinforced along a new trajectory.
And if he could alter a Fixed Spirit Origin Record—an immutable conclusion carved into the timeline itself—then surviving the Incineration of Human Order would no longer be impossible.
That's why… Shirou thought.
After living in this world for so many years, recalling the events of his previous life and the structure of the Nasuverse came unnaturally easily. The system must have been synchronizing with him since birth.
The current Fixed Spirit Origin Record ends in 1994…
The nearest and most significant convergence point is the Fourth Holy Grail War.
The Fuyuki Fire represents only a partial conclusion…
And the most critical outcome—Lord El-Melloi II inheriting modern magecraft.
"I know every major conspiracy," Shirou murmured inwardly.
"And many of them… can be changed."
Thoughts flashed through his mind like lightning. For a brief moment, excitement stirred in his chest.
But it vanished just as quickly.
The more significant the fixed record, the harder it was to alter. Knowledge was his greatest advantage—but also his greatest vulnerability. A single deviation could trigger an uncontrollable butterfly effect.
He needed to be careful.
"Shirou?"
Ayaka Sajō, standing in front of him, tilted her head slightly. Seeing his unfocused gaze, she instinctively looked toward her parents, unsure of what to do.
At that moment, Shirou's parents returned.
After exchanging polite greetings with the Sajō family, they called out to him.
"Shirou, have you made a new friend? We're about to leave."
The voice snapped him back to reality.
Shirou looked up quickly and offered an apologetic smile.
Ayaka froze.
For a brief moment, her eyes lost focus as she turned toward him—but Shirou was already walking away with his parents.
Ticket check.
Boarding.
Departure.
Fuyuki City wasn't far from Kanfuko—but it wasn't close either. The journey would take several hours.
After a short conversation with his parents, Shirou turned his gaze toward the scenery flowing past the window.
But his thoughts were already elsewhere.
The first video…
Editing required no physical tools. Everything happened within his mind. All he needed to do was recall the relevant scenes and structure them into a coherent "broadcast."
And then—an idea took shape.
Germany — Einzbern Castle
"Irisviel. Emiya Kiritsugu."
An elderly man with a trimmed beard frowned slightly as he looked at the two standing before him.
"Do you understand the purpose of this journey to Fuyuki?"
"We do, Acht," Irisviel replied calmly.
Kiritsugu nodded in agreement.
Suddenly, all three of them lost their vision.
When it returned, an enormous luminous projection hovered in the distance—passing through stone walls as if they didn't exist, suspended silently in the sky.
"Acht… do you see it?" Irisviel asked.
"You see it too?" Kiritsugu added.
The old man's brows furrowed deeply.
"Some kind of Caster's magecraft?" he muttered.
"The Seven Servants haven't even been summoned. The Holy Grail War hasn't begun."
Before either of them could respond, text appeared across the glowing screen.
The video is about to begin. Please read the following notices carefully.
First: This video concerns the past, present, and future. Viewer discretion is advised.
Second: Due to the existence of multiple space-time entities across parallel worlds, identical individuals may appear. These projections are not aligned with the viewer's future.
Third: To enhance viewer interaction, the barrage system is enabled.
By default, messages are limited to your current time-space.
Cross-temporal communication is possible, but will consume magical energy.
Please act within your limits.
A fourth notice began to appear—
And at that exact moment, the announcement echoed throughout the entire magical world.
Fuyuki City — Tohsaka Residence
"…Aoi. Do you understand?"
Tohsaka Aoi looked at her husband. Her eyes were dim, yet she forced a gentle smile.
"I understand, Tokiomi. From the moment I chose to marry into the Tohsaka family… I was prepared."
"Sakura has inherited the Matou family's magecraft," Tokiomi said quietly.
"She will surely—"
His words stopped abruptly.
His expression froze.
Aoi noticed immediately. "Tokiomi… you see it too?"
He stared at the empty air, disbelief etched across his face.
"…Yes."
At that moment—
"Mom! Dad!"
A young girl with twin tails rushed out of the room.
"There's something like a TV floating in the air! I can't turn it off!"
"Rin can see it too?" Aoi exclaimed.
Rin nodded vigorously.
And before their eyes, the screen brightened.
