Scáthach blinked when she heard Izumi's sudden proposal.
"Move the Land of Shadows?"
It was something she had never once considered.
But when she thought about it, there was nothing stopping her.
After all, the Land of Shadows had already been exiled by Alaya and Gaia to the outer edge of the world.
If it existed on the fringes of reality, then "moving" it hardly made a difference.
And Izumi's world—
it was far more vibrant, far more chaotic, far more fun than the Type-Moon world.
Moving her realm there… might actually be interesting.
Scáthach gave a decisive nod.
"Very well. We shall move it."
She rose, closed her crimson eyes, and began chanting lowly.
"Unknown fortress of shadows."
"Fortress I command, fortress I possess."
"Descend from the sky—come to my hand."
The sky above Fuyuki City rippled, and the spectral silhouette of the Land of Shadows appeared above the clouds like a phantom continent.
The next moment, under Scáthach's control, the landmass shrank—
shrinking, shrinking—until it was small enough to fit within the palm of her hand.
Izumi stared blankly.
"…You can just grab a whole world like a toy?"
Scáthach held the miniature castle effortlessly.
"Now then," she said calmly. "What comes next, boy? Your world?"
Izumi didn't hesitate.
"Don't resist."
Those simple words were all he spoke before he pulled Scáthach into the small world he controlled.
...
Scáthach stood in Izumi's private dimension, inhaling quietly.
Then—she smiled.
"Interesting. Quite an amusing place you've made."
She released the miniature Land of Shadows—
and the world responded.
In that instant, Izumi felt something shift—
something profound.
His Model Star Simulation—the very foundation of this world—
began fusing at a faster rate.
"…What?"
Izumi's eyes widened.
"You mean absorbing another world accelerates the fusion process?"
The Land of Shadows wasn't just a territory—
it was a complete micro-world.
And by integrating into his own dimension, it directly strengthened his system.
Izumi checked his status.
His strength was nearing a breakthrough to the four-digit realm.
A terrifying possibility came to mind.
"So I can increase my power by consuming other worlds' cosmologies…?"
His lips curled.
If he absorbed the entire Type-Moon universe, what would he become?
He quickly dismissed it.
"Alaya and Gaia would fight tooth and nail before handing over their world."
He could force it—
but those two little brats would absolutely resist.
And frankly?
He didn't feel like dealing with a temper tantrum from the planet's twin guardians.
When Scáthach finished integrating her realm, she frowned slightly.
"Strange. I feel… connected. As if I've formed a bond with this world?"
Izumi paused, then examined the link.
"…You're right."
"Our relationship is now similar to Master and Servant."
"And moreover—"
He lifted a hand, amused.
"I can use your Noble Phantasms. Without cost."
Scáthach raised an eyebrow.
"It feels like I've been swindled."
She thought for a moment, then shrugged.
"Ah well. What's done is done."
...
They returned to Tohsaka Rin's house, where everyone waited.
Izumi turned to the knight in blue armor.
"Artoria. Do you want to come to my world as well?"
Artoria Pendragon considered it.
"…Very well."
Then she added, almost casually:
"But I will be bringing Camelot."
Izumi nodded without hesitation.
"Sure. Works for me."
The girl beside Artoria—Leff—nearly exploded with excitement.
"That's amazing! Ancestor-sama, please bring everyone!"
"My brother and the whole family will celebrate your arrival!"
Izumi resisted the urge to sigh.
"This girl really believes Artoria is her ancestor…?"
Still, more worlds meant more power.
And Artoria's domain wasn't something to refuse.
Artoria stepped forward, summoned Camelot, and compressed it just as Scáthach had.
Izumi helped place it beside the Land of Shadows.
Two great cities now stood proudly in his world.
He looked upon them with satisfaction.
"If I can't steal the whole Type-Moon universe, I'll just dig it out piece by piece."
And with every addition, his power rose—
even if only slightly.
"Maybe someday, I'll even pull Gensokyo in."
The thought delighted him.
...
Once everything was settled, Izumi sent Illyasviel, Miyu, and the others back to the Prisma Illya world.
Even Emiya Shirou returned.
As for Gilgamesh (child)—
he stayed in Rin's world.
"Makes no difference where I am. Everything will converge in the end,"
he said lazily.
After tying up all loose ends, Izumi turned to Rin with a wicked smile.
He stared long enough for her skin to crawl.
"Alright, Rin-san."
"Be a good girl and become my maid."
He held up a maid outfit.
Rin's face went flat.
"…You're actually serious?"
She wanted to die.
"Damn it… A year as his maid…?"
And knowing him—what if I end up pregnant by the end of it—!?
Her face drained of color.
Izumi laughed at her despair.
"Relax. I'm not that cruel."
"You don't have to wear the outfit. Just handle housework."
"Anyway—time to go."
Rin exhaled in relief—
but her soul still looked crushed.
"…Fine."
"But you'll help me create an identity over there."
"I want to attend school in your world and study magic—no, magick."
Living in another world for a year didn't sound entirely bad.
Dangerous, maybe.
But interesting.
Izumi nodded instantly.
"Sure. A new identity is no problem."
