Demon Slayer Corps Headquarters · Main Hall
"Lord Takumi, how do you plan to eliminate Muzan?"
The question echoed through the hall, but this time, the world was already shifting. The air trembled faintly as Takumi—Herrscher of Finality, master of dimensions, and future founder of a new civilization—folded his arms calmly.
Takumi smiled lightly. "Eliminate Muzan? Easy. But what matters isn't Muzan. It's what happens after Muzan. We're building a future. A nation. A civilization that spans worlds."
The Hashira stiffened. This wasn't the answer they expected.
Kagaya Ubuyashiki leaned forward, his voice calm yet curious. "A civilization… across dimensions? Mr. Takumi, do you mean the 'Dimensional City' mentioned in your earlier description?"
"Exactly." Takumi nodded. "Killing Muzan is just a stepping stone. The real goal is to relocate everyone to a safe world and build a high‑tech nation—Dimensional City. A place where no one fears demons, where talent like yours can finally grow without restraint."
The Hashira exchanged shocked looks.
Rengoku's voice boomed first. "A world of safety and progress—truly splendid! Lord Takumi, if that is your vision, then we shall follow it with all our hearts!"
Beside him, Mitsuri Kanroji's eyes sparkled like stars. "So cool… A city from another world… Lord Takumi is amazing…"
Takumi looked away momentarily, trying not to stare at her overwhelming… presence.
Focus, Takumi. Civilization building first. Boobs later.
He coughed lightly. "Anyway. Muzan first. Relocation second. Civilization building third. And yes, I can find Muzan anytime I want." His golden eyes glowed slightly. "Herrscher of Finality doesn't lose track of small fry."
The Hashira stiffened. They weren't sure what a Herrscher was—but instinctively, they knew it was terrifying.
Kagaya bowed his head slightly. "We trust you. But before relocation, allow us to offer what help we can. Even if demons are weak compared to you, we—"
"I won't stop you if you want to participate." Takumi cut in. "Think of it as closure. After centuries of war, you all deserve to witness the end."
A unified shout exploded through the hall.
"Yes, Lord Takumi!"
Takumi nodded once. "Good. Prepare the Corps. After Muzan is gone, we move to the Slime World. From there, Dimensional City will rise."
Treating Kagaya & Gyomei – The First Display of Divine Power
Before leaving, Kagaya asked gently, "Mr. Takumi… about what you said earlier… curing our bodies… Is such a miracle truly possible?"
Takumi raised his hand. Golden Finality energy condensed instantly—pure, radiant, overwhelming.
Two orbs split off, one large, one small.
The large one flowed into Kagaya.
The smaller into Gyomei.
A second later—
Gyomei gasped as his eyes filled with light for the first time in years. "I… I can see! Lord Takumi, I can truly—see!"
Kagaya's decayed skin regenerated. His curse dissolved like dust. His body straightened, strengthened—and for the first time in his life, he stood tall without support.
The Hashira cried out.
"MASTER!!"
"UNBELIEVABLE!"
"LORD TAKUMI IS A MIRACLE WORKER!"
Kanae covered her mouth, eyes softening as she stared at Takumi. Somehow… he looked even more dazzling than before.
Takumi scratched his cheek awkwardly. "It's just a small trick. Anyway, I'm heading back to the Butterfly Mansion. Kanae, walk with me."
"Yes, Lord Takumi." Kanae bowed gently and moved to his side.
As Takumi left the hall, the Hashira knelt on one knee.
"FAREWELL, LORD TAKUMI!" ×8
Butterfly Mansion · Afternoon
Back at the mansion, Takumi wasted no time.
He sat cross‑legged, swallowed a high‑grade cultivation elixir, and began refining it. Spiritual energy surged like a flood.
Crack… crack… BOOM!
His golden core shattered.
A tiny figure formed—his Nascent Soul.
His power skyrocketed.
Nascent Soul Middle Stage… Late Stage… Peak.
A thousandfold increase.
Takumi exhaled. "Hooo… not bad. Not bad at all. With this strength, when I return to the Slime World, even Guy won't scare me."
He opened his system interface.
Host: Takumi
Title: Herrscher of Finality
Realm: Nascent Soul Peak
System: Civilization Development System
Goal: Establish Dimensional City
Items: Dimensional Gate, 4× Leibi, Whisper Core
Evaluation: Already a big shot, but still able to be stepped on if you're careless.
Takumi scoffed. "Stepped on by what? This isn't a xianxia world… probably…"
System: "Host, please maintain humility. Universe is big. Don't randomly provoke things you can't afford. □(•̀ᴗ•́)و"
Takumi ignored it.
"Time to return to Rimuru. Hehehe… this time, I'll make that slime's jaw drop!"
Slime World – Rimuru Awakens to Something Terrifying
In the center of Goblin Village, the small slime Rimuru—who had fainted from magicule exhaustion—shivered violently.
The goblin girl watching him screamed.
"Village Chief! Something is wrong! Lord Rimuru is shaking!!!"
The goblin elder rushed over.
But the real cause…
Was something far beyond their imagination.
A dimensional ripple appeared above the sky.
And through that ripple—Takumi's presence pressed upon the world like a descending star.
A new era was beginning.
The era of Dimensional City.
