The day after being summoned, Mayuri left Mount Enzou.
With black wings unfurled behind her, Mayuri flew at low altitude for about three minutes before entering Fuyuki City.
Beneath her feet lay the streets she had walked through during the four wars.
Or rather, it used to be.
The asphalt road surface had been burned black, cracked, and sporadic flames were seen rising from the cracks.
Most of the buildings on both sides of the road are now just frames.
A convenience store with half of its exterior walls collapsed, a residential building with its roof burned down, and a shopping mall with only a steel frame remaining.
The shop window glass was completely shattered, and the shards were scattered everywhere by the heatwave, making a creaking sound when stepped on.
The utility poles lay crookedly on the road, their wires dangling to the ground.
The traffic light was reduced to a single pole; the light head had fallen to the ground and was burned black.
The vending machine lay overturned on the roadside, its outer shell burned and deformed, and all the beverage cans inside had bulged and burst open.
There were charred black marks on the road surface.
Its shape resembles the outline of a person.
Mayuri glanced at it once and then looked away.
There wasn't a single living person in sight.
She walked south along the main road for ten minutes, passing the location of the Tohsaka Residence where she had lived during World War IV.
That area has been burned to the ground.
Even the huge crater she blasted was filled in by flames and collapse.
wrong.
This is Singularity F.
The timeline is 2004, the Fifth Holy Grail War.
The Fourth Holy Grail War took place ten years ago.
The Tohsaka Residence was destroyed by Mayuri's lightning ball during the Fourth Holy Grail War, and the Tohsaka Family should have rebuilt it on the original site ten years later.
But in this altered Singularity, whether it has been rebuilt or not, it has now been burned to the ground.
Mayuri continued walking.
We passed through the commercial street, the port area, the residential area, and the Shinto.
It's the same everywhere.
Ruins, flames, ashes, scorch marks.
There isn't a single intact building.
Even half a building is hard to find.
The entire Fuyuki City was as if it had been pressed down from the sky and crushed by a giant hand, which then set it on fire.
Mayuri settled on a commercial street in Shinto.
The black wings were tucked behind him.
She walked on a path strewn with broken glass and ashes.
I stood there for a while.
She came to this street during the Fourth World War.
Back then, there were streetlights, roadside trees, and shops that were open for business.
She remembered there was an arcade here, the one that Young Gilgamesh frequented.
She remembered there was a working vending machine at the intersection where she had bought iced cola.
Now everything is gone.
The arcade sign hung crookedly on the wall, with only two charred characters remaining.
The vending machine lay on the road, its contents reduced to a lump of molten plastic and metal.
Mayuri stood on the broken glass for about ten seconds.
Then keep walking.
She wanted to see where the borders of Fuyuki City were.
After walking north along the highway for about twenty minutes, the buildings became fewer and fewer, and the road surface became increasingly dilapidated.
We walked forward for about five minutes.
Mayuri stopped.
There's no road ahead.
The road isn't blocked.
Everything is gone.
The asphalt road underfoot ended about ten meters ahead.
The road doesn't end at a cliff, a break, or a wall.
It is nothingness.
Mayuri stood at the edge of the road, looking ahead.
There was no sky, no ground, no color, and no light ahead.
It's not black.
Black is also a color.
There isn't even black here.
It's like someone painted a city on a canvas, and then stopped painting there.
Nothing exists beyond the edge of the canvas.
Mayuri extends her hand.
My fingertips reached into that void.
There was no resistance.
There was no temperature either.
There was no tactile sensation either.
The finger disappeared into nothingness and then reappeared.
Intact and undamaged.
Mayuri tried again.
This time, put your whole palm in.
It's still the same.
I felt nothing.
My hand was unharmed after I pulled it back.
But she was certain of one thing.
There's nothing there.
There was no land, no air, no magic, no concept.
That concludes the story of Singularity F.
Fuyuki City is the entirety of this world.
We can't get out.
Mayuri withdrew her hand and turned to walk back.
From now on, the only place I can move around in is this small area of Fuyuki City.
After returning to the large pit at Mount Enzou, Mayuri began to consider a practical problem.
live.
The bottom of the pit was full of rubble and exposed rock layers, with no place to block the wind.
Although it wasn't raining under the dark red sky, the smell of ash and sulfur in the air was very unpleasant.
Servant's body does not need rest or sleep.
Mayuri couldn't just stand by the Holy Grail and wait.
She needs some basic necessities of life, otherwise she will have mental health problems.
Mayuri decided to go out and search for supplies.
She flew out three more times in the next two days.
On the first trip, they found a relatively intact single mattress in a partially collapsed residential building and flew back with it using their wings.
One corner of the mattress was charred and smelled burnt.
Just make do with it.
On the second trip, they found a piece of advertising cloth from the ruins of the commercial street. It was unwashable, but it was large enough when unfolded.
She built two makeshift walls out of rubble in a recess inside the pit and used advertising cloths as a roof.
The third trip yielded the greatest harvest.
She found more than a dozen unopened cans of food in the ruins of a collapsed convenience store, mostly sweet corn and luncheon meat.
There are also two unbroken bottles of mineral water.
Servant do not need to eat.
But Mayuri still brought them all back.
Sitting in the makeshift shed he built, he opened a can of sweet corn and ate it with his fingers.
The taste was so-so.
The canned corn was overcooked by the high temperature, making the kernels too soft and the sweetness much less pronounced.
But as she chewed, Mayuri felt that at least she was still alive.
When the Fourth World War ended, she finally obtained a real physical body, but before she could even enjoy it for a few days, her original body in the Throne of Heroes was pulled into this Singularity.
She turned back into Servant.
It's the reverse version.
Mayuri chewed on sweet corn and wrapped herself up in black wings.
Although the feathers are black, they feel just as soft to the touch as when they were white.
That's alright.
Several days passed like this.
Shirou Emiya would occasionally return, catch a glimpse of Mayuri from afar at the edge of the pit, and leave after confirming that there was nothing wrong with the Holy Grail.
There wasn't much communication between the two.
Shirou Emiya is not a talkative person.
Mayuri didn't want to get close to him either.
Day 6.
Mayuri was sitting in the shed eating a can of luncheon meat when she suddenly sensed a presence.
It's not Shirou Emiya.
She had already memorized Shirou Emiya's Spirit Origin reaction.
This newly emerging aura is completely different.
Unlike Servant, they resemble humans, but are far stronger than ordinary humans.
It contained a very ancient, mysterious magical energy.
Mayuri put down the can.
The visitor did not enter from the edge of the pit.
He appeared directly inside the large pit.
It's as if some kind of teleportation or spatial jump was used.
Mayuri's senses swept around the perimeter.
Shirou Emiya was still on his patrol route and showed no unusual reaction.
In other words, Shirou Emiya was completely unaware of the visitor's presence as he passed through the outer defensive line.
They were completely ignored.
Mayuri came out of the shed.
A man stood beside the altar in the center of the pit.
Long, wavy hair, dark brown with a hint of burgundy, and black eyes.
He was wearing a dark green top hat.
He was wearing a long, thick wool coat in the same color family, with black fur trim on the cuffs and collar.
He wore a black vest, a purple tie, dark joggers, and black knee-high boots.
His demeanor is very much like that of a gentleman scholar from the Victorian era.
But Mayuri first saw him, the image that popped into her mind was neither gentleman nor scholar.
It's just a nickname.
Grand Bomber.
Lev Lenore Flauros.
The human vessel of the 64th pillar of the Seventy-Two Demon God Pillars.
The perpetrators of the Chaldea bombing.
The murderer of Olga Marie.
The executors of the plan to Incineration of Humanity.
One of the core villains in the first part of FGO.
Lev stood beside the altar, scrutinizing Mayuri as she approached.
His gaze lingered for two seconds on Mayuri's black wings and the red and black halo above her head.
"So you're the new Guardian Servant summoned by the Holy Grail?"
"Judging from your appearance, you seem to have some skill."
His tone was that of someone in a superior speaking to a tool.
It's only natural to be in a superior position.
"After that, all you need to do is diligently protect the Holy Grail for our King."
"Destroy all invading enemies."
Did you understand?
Mayuri stood five meters away, watching him.
Her rose-red eyes were expressionless.
She mentally reviewed this person's resume.
Lev Lenore.
Flauros.
He remained hidden in Chaldea for sixteen years.
A near-future observation lens, Sheba, has been developed.
Trusted by everyone.
Then, in 2015, the Spiritron Transfer chamber was detonated.
All forty-seven Master were critically injured and fell into a deep sleep.
Numerous staff members died.
Finally, he pushed Olga Marie into Chaldeas.
