Morning light shone upon the riddled wilderness.
The decision to disband the Demon Slayer Corps had already been handed down, and the surviving swordsmen were celebrating their hard-won peace.
Yamada didn't join the festivities. He held Shinobu's hand, and the diamond-shaped mark on his palm, emitting a faint starlight, suddenly lit up.
A deep portal, like a galaxy swirling backward, slowly opened before them.
"Let's go, let's see our new home."
Yamada chuckled, picked up the exclaiming Shinobu by her waist, and stepped into the starry portal.
After a brief sensation of weightlessness, the scene before them suddenly opened up. It was a massive island floating in the depths of the boundless universe.
On the island were not only verdant mountains and clear lakes but also an exquisite and massive courtyard standing at its center.
Above were brilliant nebulae, beneath their feet was soft grass, and the air was filled with a refreshing scent that cleared the mind.
"Is this the private island you mentioned?" Shinobu jumped down from his arms, her purple eyes reflecting the starlight from across the sky, her face full of disbelief.
"This is like the residence of a god from mythology."
"Do you like it? This place is called a Miniature Divine Realm."
Yamada put his hands in his pockets, surveying the surroundings.
"In this dimension, I am the absolute creator. No outside creature or even energy can invade without my permission. Moreover, as long as you are within the Divine Realm, the passage of your lifespan is completely frozen. In other words, here, you are ageless and immortal."
Shinobu was too shocked to speak.
Breaking the iron law of birth, aging, sickness, and death was a miracle that many could only dream of.
"You can usually prepare medicine and rest here."
With a thought from Yamada, a large empty space next to the courtyard instantly rose from the ground, transforming into a modern medical laboratory with world-class equipment.
"When I go out to 'hunt', this will be your safest haven. Once I settle down in the new world, I'll open the door to take you out shopping anytime."
Looking at that laboratory full of futuristic technology, the light in Shinobu's eyes grew brighter and brighter.
For a doctor passionate about pharmacological research, this was an irresistible temptation.
"But what if you get injured outside?" She turned her head, still asking with some concern.
"Don't worry, I'm very cautious." Yamada ruffled her long hair.
"You don't need to worry so much, just wait for me here obediently."
After settling Shinobu, Yamada walked alone to the edge of the Divine Realm.
Ahead was the vast sea of stars.
He took a deep breath and communicated with the system in his mind.
'System, open the passage to the new world.'
[Ding! Command confirmed!]
[Deducting 10,000 Dimension Points, opening the crystal wall system dimensional passage...]
[Target world locked: Jujutsu Kaisen]
[Current time node: Spring, 2006]
[World Background Analysis: This is a world shrouded in negative emotions. The overflowing negative emotions of humans, such as fear, resentment, and jealousy, will converge into monsters called Cursed Spirits. Those who exorcise Cursed Spirits are called Jujutsu Sorcerers. At the current world time node, the strongest duo in the Jujutsu world—Gojo Satoru and Geto Suguru—are about to undertake a critical mission before Tengen's assimilation: protecting the Star Plasma Vessel, Amanai Riko, Meanwhile, an assassination organization has already hired the Sorcerer Killer, Fushiguro Toji, to carry out an assassination.]
[Mission Objective: Forcefully intervene in the Star Plasma Vessel incident, change the fate of key characters (Gojo Satoru, Geto Suguru, Fushiguro Toji, Amanai Riko, etc.), and harvest Dimension Points!]
Listening to the intelligence summary in his mind, the corners of Yamada's lips curled into a sharp arc.
Cursed Energy system?
Gojo Satoru's Limitless? Fushiguro Toji's Heavenly Restriction?
"Sounds much more interesting than those demons who only know how to linger in the dark."
"Let's go."
Yamada took a step forward, and his entire body instantly merged into a blinding white light.
—
2006, Tokyo, Japan.
The streets of Shinjuku.
Traffic flowed like water, and neon lights flickered. Salarymen in suits hurried along, and large screens on the street played popular songs from the early 2000s.
An imperceptible spatial distortion flashed briefly in a deserted narrow alley.
Yamada, wearing a pair of black leather boots, stepped out from the shadows. He had changed into a black trench coat that suited modern aesthetics, with a dark shirt underneath. His Kusanagi Sword was wrapped in a long gray cloth, looking like a long musical instrument, carried casually in his hand.
As soon as he stepped into this noisy concrete jungle, Yamada frowned slightly.
In his perception, the air of this city was filled with a nauseating, thick aura.
Near a crosswalk not far away, on the shoulder of a decadent middle-aged man looking down at his phone, crouched a deformed monster like sludge, covered with several eyeballs.
While gnawing on the man's neck, it emitted incoherent murmurs. "Don't want to work overtime... I want to die..."
Although the man couldn't see it, his face was pale, and his shoulders seemed to be weighed down.
"An aggregation of negative emotions, so this is a so-called Cursed Spirit?"
Without even activating his Sharingan, Yamada easily saw through the essence of this thing relying purely on his Chakra perception.
He snapped his fingers.
Snap.
A wisp of lightning, almost invisible to the naked eye, shot through the air and entered the body of that low-level Cursed Spirit.
There was a soft sizzle.
Before the Cursed Spirit could even scream, it was instantly evaporated clean by the high temperature of the lightning.
The decadent man felt his shoulders suddenly lighten. His originally groggy brain cleared instantly, and he rolled his neck somewhat blankly.
"It's not much trouble to deal with." Yamada withdrew his gaze.
To act smoothly in this modern society, he first had to solve the issues of identity and money.
'System, exchange for a legal local identity plus a sum of startup capital.'
[Ding! 100 Dimension Points consumed.]
[A legal identity has been generated for you: Tanaka Yamada, a freelance investor who lived abroad in his early years. Includes identification documents and a bank card containing ten million yen.]
