Mayuri nodded without saying a word.
Walk.
Let's go now.
Immediately. Right away.
She'd had enough of this godforsaken place—all ruins, empty cans, and silent archers!
Then she suddenly remembered something very, very important.
"... Can't leave."
Mayuri's voice deflated like a punctured balloon.
Olga Marie was kneeling in front of her, her golden eyes filled with the warm glow of "I've come to take you home."
Upon hearing those three words, the warmth and radiance shattered with a snap.
What do you mean by "can't leave"?
"My Spirit Origin is directly bound to the Holy Grail of this Singularity."
Mayuri huddled under the blanket, her voice muffled.
"If I force myself to leave, my Spirit Origin will collapse. To put it simply, the moment I step out, I'll be like a television that's been unplugged—snap, the screen goes black."
Olga Marie's expression went through three stages of change.
shock.
think.
The subtle frustration of "I traveled a long way to pick you up, only to be told the door was locked and the key was still inside"
Why couldn't you have said so sooner!
You didn't ask either.
"Does this even need to be asked?!"
Mayuri pulled the blanket up a little, revealing only a pair of rose-red eyes.
Those eyes flickered.
However, it's not entirely without a solution.
She stretched a hand out from under the blanket and pointed to her stomach.
To be precise, it refers to Leviathan, who is dozing at the bottom of the Great Hollow.
"It swallowed Medusa before. Medusa possessed a Holy Grail."
"The Holy Grail is now inside Leviathan's belly."
Olga Marie's eyes lit up.
"You mean—use that Holy Grail as a new Spirit Origin anchor, detach your Spirit Origin from the Holy Grail in this Singularity, and rebind it to the new Holy Grail?"
That's roughly the idea.
"But this transformation process is very complicated. I can't handle it alone. I need someone outside to help me stabilize my Spirit Origin structure."
Olga Marie stood up and dusted off her knees.
Her long silver hair swayed in the dark red light of the sky.
Her expression turned serious.
" Chaldea already possesses the theory of Spirit Origin transformation."
"During this period, Ritsuka Fujimaru and her companions conquered five Singularity and summoned numerous Servant through the Heroic Spirit Summoning System. Among them were several academic and Divine Era Magus- type Heroic Spirit who made significant contributions to the research on Spirit Origin."
"In short, the theoretical aspects are mature enough. I'll handle the external stabilization, and you'll be responsible for the internal autonomous reconstruction of the Spirit Origin. With proper coordination, it should be completed within half a day."
"Long time?"
Mayuri's face scrunched up.
"Half a day is too long."
"Your Spirit Origin complexity is the highest I've ever seen among all Servant. Half a day is already the most optimistic estimate."
"Okay, okay."
Mayuri stood up.
The Spirit Origin transformation was carried out next to the altar in the center of the Great Hollow.
Mayuri sat cross-legged on the ground.
Leviathan spat out the Holy Grail that had been digested from Medusa's body.
Mayuri stared expressionlessly at the Holy Grail, which was covered in saliva.
Olga Marie stared blankly at the saliva-covered Holy Grail.
"... Wipe it first."
"Um."
Mayuri used a corner of the blanket to wipe the saliva off the Holy Grail.
Then I threw the blanket away.
That blanket is no longer usable.
Olga Marie began to lay out the spell.
Her ten fingers rapidly traced Magecraft circles in the air, and pale blue light extended from her fingertips, forming a circular magic array about three meters in diameter around Mayuri.
The patterns of the spell array are extremely complex.
It is the culmination of Chaldea's theories on Spirit Origin modification accumulated during their conquest of the five Singularity.
It incorporates the research findings of several academic Heroic Spirit.
Each ray of light corresponds to a key node in the Spirit Origin structure.
"Here we go."
Olga Marie's voice became very professional.
"Disable all your Spirit Origin defenses."
Mayuri closed her eyes.
Turn off the layers of protection you have one by one.
The defensive layer of the Astral Dress was deactivated first.
Then comes the passive usurpation scene of the great sin, Envy.
Then there's the outer barrier connected by the Leviathan Contract.
Finally, there's the self-protection mechanism of the Spirit Origin.
After all the debunking was completed, Mayuri's Spirit Origin was completely exposed within the spell array.
It's like putting a heart on the operating table.
Olga Marie's forehead was beaded with sweat.
She could clearly "see" Mayuri Spirit Origin's entire appearance.
It's incredibly complicated.
The Spirit Origin structure of an ordinary Servant is like a tree—a trunk branching out into branches, with leaves growing on the branches, creating distinct layers.
What does Mayuri's Spirit Origin structure resemble?
It's as if someone tangled the roots of three trees together, stuffed a giant dragon inside, and then used the magic of the Holy Grail to mold the whole thing into a ball.
The Spirit Origin Spirit Origin of angels, elves, and Leviathan are three nested and interpenetrating Spirit Origin.
In addition, the fragments of power that Leviathan had seized after devouring various magical beasts were scattered throughout the entire Spirit Origin.
Olga Marie took a deep breath.
"Your Spirit Origin is the most chaotic I've ever seen."
"I know."
"Even more chaotic than Illya's."
"I suppose so."
"That's not right. This is Spirit Origin, not your room, although your room is messy too."
"A shed is not considered a room."
"Shut up, I need to concentrate."
The renovation has officially begun.
Olga Marie manipulated the light from the spell array to penetrate deep into Mayuri's Spirit Origin, beginning to sever the Spirit Origin nodes bound to the Singularity Holy Grail one by one.
Each time a node is severed, it must be immediately filled with the magic of the new Holy Grail to establish a new anchor point.
Mayuri has been sitting for two hours.
How much longer?
"Don't speak."
"..."
Another hour passed.
"And now?"
"There's still half left. Shut up."
Olga Marie looked up and glared at her.
Mayuri's wings immediately became still.
About two more hours passed.
"The last node."
Olga Marie's fingers made a final pulling motion in the air.
The pale blue light severed the last fiber connecting Mayuri's Spirit Origin origin to the Holy Grail in the Singularity.
At the same time, the golden magic of the new Holy Grail surged into the vacant spot.
Interlocking.
locking.
Finish.
Mayuri opened her eyes.
A golden light flashed in her rose-red pupils.
That was the sign that the new Holy Grail had been successfully bound to her Spirit Origin.
"Alright?"
"Alright."
Olga Marie sat on the ground and let out a long breath.
His long silver hair was covered in sweat.
Her magic power was significantly depleted.
Mayuri stood up.
She checked her Spirit Origin state.
The connection to the Singularity Holy Grail has been severed.
Instead, a new anchor point for the Holy Grail was established.
This means she is no longer bound to this Singularity.
You can go anywhere.
Mayuri took a deep breath.
Then she looked at Olga Marie.
"Next, let's make a contract."
"Um."
Olga Marie stood up and extended her right hand.
"A formal Master- Servant contract."
Mayuri looked at her hand.
I thought about it.
"I have one condition."
"Explain."
Does Chaldea have internet access?
Olga Marie paused for a second.
"... There is an internal local area network."
Are there any games?
" Da Vinci's workshop has some... entertainment equipment."
"Make a deal."
Mayuri grasped Olga Marie's hand.
A pale blue light emanated from their clasped palms.
Magic Circuits connection.
The contract is established.
The Command Spell pattern appeared on the back of Olga Marie's left hand: three dark red geometric patterns with Leviathan shell designs.
Mayuri looked down at the Command Spell.
"It looks pretty good."
Don't get distracted. There's still one thing to take care of.
"What's up?"
" The Holy Grail."
Olga Marie pointed to the Holy Grail floating on the altar.
The Greater Grail in Singularity F.
Mayuri has now severed ties with it.
But it's still here.
Someone has to keep an eye on things.
Mayuri turned her head and looked at the stone wall on the north side of the Great Hollow.
Shirou Emiya stood there.
I don't know when they arrived.
Amber eyes looked at Mayuri and Olga Marie.
Its expression was like that of a police dog that senses its owner is about to go on a long trip.
"Little Shirou."
Mayuri called him.
Shirou Emiya's eyebrow twitched.
He really disliked that title.
" The Holy Grail is now in your hands."
Mayuri said.
"Wasn't this your job before?"
"Now it's yours."
"Why?"
"Because I'm leaving."
Shirou Emiya glanced at Mayuri, then at Olga Marie, and then at the floating Holy Grail.
"... Understood."
His tone was like that of a corporate slave who had been forced to work overtime without being paid.
Mayuri chuckled to herself.
It laughed so hard that all four pairs of wings trembled slightly.
Then she turned around and walked over to Olga Marie.
Let's go.
Olga Marie initiated the Spiritron Transfer.
Blue light rose from beneath her feet.
Mayuri glanced back at the Great Hollow one last time.
That crooked, dilapidated shed.
That canned food mountain already possesses archaeological value.
The light grew brighter and brighter.
Mayuri and Olga Marie's figures gradually became transparent.
Shirou Emiya stood beside the stone wall, watching the two disappear.
"..."
The light faded.
He was the only one left in the Great Hollow.
And a Holy Grail.
