"Ranga, watch closely!"
"Yes, Master!"
By a quiet riverside, Rimuru stood proudly in his slime form, tiny hands raised dramatically.
"Rimuru, transform! ヾ(o･ω･)ﾉ"
His body twisted, releasing a swirl of black mist.
When the mist cleared—
A perfect mimicry of a Black Storm Star Wolf stood where Rimuru had been.
Ranga's tail wagged so hard the air shook.
"Master… majestic!!!"
Rimuru narrowed his eyes and summoned black lightning between his horns.
"Black Lightning!!!"
BOOM!!!
A massive boulder by the river exploded into fragments. Water surged up violently, forming a shimmering rainbow.
"Hehehe… too strong! I'll need to be careful using this one."
"As expected of my Master!!" Ranga declared proudly.
Rimuru nodded grandly. "Experiment over! Let's go home, Ranga!"
He hopped onto Ranga's back as they dashed across the plains.
Rimuru looked at the lively Goblin Village ahead.
"Ahh~ Peace. Truly the best!"
Peace Interrupted
"Mm-hmm, perfect! Perfect! As expected of Kajin!"
"Is that so? Is it really that perfect? And who is Kajin? Hm?"
A familiar voice.
Rimuru froze.
Then jumped.
"TAKUMI!!!! You're back!!"
Rimuru launched his round blue body straight into Takumi's arms.
Takumi caught her easily.
"Yes, I'm back! Did you miss me?"
"Hmph!! You said a few days! It's been almost a month! I didn't miss you at all!"
Takumi chuckled.
"Yes yes, my fault. Please forgive your dearest friend."
Rimuru puffed up proudly. "Mmm… fine, you are forgiven!"
Ranga rushed forward and bowed.
"Lord Takumi, welcome back!! Your subordinate is honored to see you safe!"
Takumi stroked his fur. "Hehe, thanks, Ranga."
Rimuru bounced excitedly. "Takumi! Everyone evolved! Ranga became Ranga! The Goblins became Hobgoblins!"
"And the Village Chief… hehehe… he changed a LOT."
Takumi smirked.
He remembered the anime scene.
The fragile old goblin turning into a BURNT-STEAK MUSCLE GIANT.
"I have to see that."
Takumi lifted Rimuru.
"Oh right—Rimuru, I brought you a gift."
"A GIFT?!" Rimuru vibrated with excitement. "WHAT IS IT?!"
"Hehe~ You'll see."
The Gift That Was… An Entire Population
Takumi led Rimuru deep into the forest.
Bushes parted.
And thousands of people appeared.
Hashira.
Demon Slayer Corps.
Families.
Doctors.
Craftsmen.
Rimuru's eyes became dots.
"Ta… Ta… TAKUMI—WHAT IS THIS?!!"
"Hahahahaha! This is the gift."
Everyone rushed forward.
"Lord Takumi, welcome back!"
Rimuru trembled in Takumi's arms.
"Takumi!! Why are there SO MANY HUMANS!! Why are THEY STARING AT ME?!"
Especially the girls.
Their eyes sparkled.
"Kawaii!!"
Rimuru realized—
Slime + round + soft = girl magnet.
Meanwhile, the System: Put down Nezuko—I mean, put down Rimuru! Let ME carry her!!
Takumi introduced Rimuru proudly.
"Everyone, this is Rimuru—Goblin Village's leader and my dear friend."
The Demon Slayers knelt.
"Lord Rimuru!! Please guide us!!"
Rimuru panicked.
"Eh?! Eh?! O-okay! Please get up! I'm not used to being treated like this!"
Takumi nodded with satisfaction.
"That's enough. Let's go meet everyone in the village."
He presented Kagaya next.
"Rimuru, this is Kagaya Ubuyashiki—former leader of the Demon Slayer Corps."
Rimuru extended a tiny hand.
"Nice to meet you! Please get along with us from now on!"
Kagaya smiled gently and shook it.
"The pleasure is ours, Rimuru."
Arrival at Goblin Village
As Takumi led the massive crowd toward the village…
Goblin guards nearly fainted.
"L-Lord Rimuru!!! Humans! Many humans! A whole ARMY?!"
"No panic!" Rimuru declared proudly. "These are guests!"
Then whispered to Takumi.
"Takumi… you brought a whole COUNTRY."
Takumi smirked.
"Just preparing the foundation for the future Dimensional City."
Rimuru's eyes sparkled.
"D-dimensional… City?"
"Yes." Takumi looked toward the horizon.
"A country that spans worlds. A civilization beyond imagination. And today—this is the beginning."

Takumi grinned.
"So the system is reacting… good. Very good."
Rimuru looked up.
"What now, Takumi?"
Takumi held him higher.
"Now—we build a nation."
Rimuru blinked.
"A nation?"
"A nation that will shake the multiverse."
The wind blew across the grasslands.
Thousands of Demon Slayers stood behind Takumi.
The evolved Goblins stood before Rimuru.
Two leaders.
Two worlds united.
And the foundation of Dimensional City had officially begun.
