The King of Curses. Disgraced One. Imaginary Demon.
In the original Jujutsu Kaisen, Ryomen Sukuna was known by many names. Feared and dreaded by jujutsu sorcerers, and for good reason.
Partly because of his overwhelming power—he steamrolled the jujutsu world a thousand years ago.
And partly because...
"Graaahhh—..."
In the middle of the room, a grotesque and eerie curse formed seemingly out of nowhere.
This one was born from Mizunozuki Seishu's own cursed energy combined with the overflow of negative emotions from his neighbors in the old neighborhood.
Thanks to Sukuna's template, things that regular people would perceive only as abstract, invisible negativity… now had a clear and horrifying "form" in Seishu's eyes.
Looking at this newly born curse under his full control, Seishu found it pretty interesting.
Because this freaky curse was basically an extension of his own senses—he could see the world from its point of view.
In simple terms: this curse acted like Seishu's extra pair of eyes. Even if he wasn't physically near it, he could still see whatever happened around it.
Super convenient.
This worked because the curse carried Seishu's own cursed energy.
And it was decently strong too—Grade 2.
According to Jujutsu Kaisen's original system, curses were ranked as follows:
•Grade 4: A wooden baseball bat can exorcise it.
•Grade 3: A handgun will do the job.
•Grade 2: You'll need a shotgun.
•Grade 1: Even an armored vehicle might not be enough.
•Special Grade: Carpet bombing with cluster bombs still might not be sufficient.
Of course—
This ranking assumes a normal person could use modern weapons to hurt a curse.
But realistically? That's not how it works. Curses need to be exorcised using special, targeted techniques. If a regular human tried to fight a curse, even a nuclear bomb would just look like fireworks to it.
So, being able to create a Grade 2 curse from nothing but cursed energy and neighborhood negativity? Not bad at all.
Seishu gave it a casual kick, sending it flying into a discarded cardboard box.
He'd thought about it enough. It was ugly and annoying to look at anyway.
Because yeah, it was scary as hell.
He gathered a mass of cursed energy in his palm—the King of Curses had honed his control for over a thousand years. Now, Seishu could use that power like it was second nature.
He finally had the means to make real moves in the real world.
Which meant...
The opening act needed the right cast.

The Next Morning
Seishu got up early.
Thanks to his enhanced body and Sukuna's template, he barely needed sleep anymore—he'd basically kicked that "bad habit."
The morning sun shone gently outside.
Even though he was now strong enough to casually say "I don't eat beef," Seishu obediently went to school.
To hide in plain sight is to hide best.
If he was going to be a mastermind, he couldn't just lurk in the shadows.
Anyone scheming from the sewers would be immediately labeled suspicious.
Especially in this crossover anime world—with one particular detective-lover hanging around.
Yep.
Shinichi Kudo , the future death god of elementary schoolers (wherever he goes, people die), also existed in this world.
But from what Seishu observed, in this daily-life crossover setting, Kudo wasn't nearly as lethal.
At most, he was just a smart guy who liked butting into police investigations.
Still, with characters like that around, Seishu knew he had to keep a tight grip on his current identity—harmless high school student.
At least until he was strong enough to steamroll the world, he couldn't let these people find a single weakness to exploit.
Also, the system had a note.
Not everyone in this crossover world could be deceived for big system point gains.
Simply put: the more important a character was in the original series (higher screen time), the more system points Seishu could earn by tricking them.
So Seishu confirmed one thing:
All these protagonists and major side characters probably had some kind of plot armor or "fate buff" going on.
Which only increased the chances of him getting screwed if he slipped up.
He was trying to kick off a supernatural awakening, after all—and that would involve bloodshed.
Any bloodshed, and those detective types would sniff him out like rabid dogs.
So he decided to lay low.
He wasn't afraid, just practical.
No need for unnecessary trouble, right?
If he wanted to win in the end, he'd have to play it smart now.
On the train.
Seishu's newly optimized good looks caught a lot of stares on the crowded commuter train.
Several high school girls on their way to school began chattering excitedly.
Some even sneakily glanced his way, then compared his school uniform to theirs—and quickly figured out which school he went to.
Sobu High School.
"Hey hey! That guy is super handsome!"
"Where?! OMG, total hottie!"
"Shhh! Keep it down, he might hear us!"
Seishu, with his enhanced hearing, of course heard them—but he didn't mind being stared at or even secretly photographed.
If they're cute, why not let them fangirl a little?
He had the looks—might as well use them.
He gave a friendly nod and smile to the loudest group of girls, causing one of them to let out a loud, lovestruck squeal.
Suzuki Sonoko, with her bestie Mouri Ran.
Main girl and side girl from the original Detective Conan. Seishu had his eye on them too.
But for now, they weren't the top priority.
His main focus was…
Miko Yotsuya.
The heroine from Mieruko-chan (aka The Girl Who Can See Them), who awakened powerful spirit vision in the original series.
But in this crossover slice-of-life world?
She was just a regular girl.
Interesting.
Yotsuya-san, you better wake up soon…
That insane spiritual vision from the original—where'd it go?
Seishu was a kind soul, after all.
He couldn't just stand by while such a cute girl lost her original "golden finger" (i.e., her special ability).
And besides...
Wasn't this the perfect opportunity?
Curses were naturally invisible to ordinary people.
Even more extreme than the ghosts in Mieruko-chan.
Whether you could see them or not—they'd still kill you.
Time to give Yotsuya-san a little scare. Something that'll really make her wet her pink panties in terror.
Currently, Miko had no spirit vision and couldn't see ghosts or weird stuff.
So she didn't tremble in fear like in the original.
And if she didn't tremble in fear… Seishu couldn't enjoy the absolutely beautiful sight of her soaking her pastel pink underwear.
That just won't do.
To Seishu, a Miko who wets herself in fear… is the best kind of Miko.
"Achoo—!"
Miko sneezed suddenly, prompting concern from her friend Hana Yurukawa .
But Miko just looked a little confused.
She'd felt a weird chill down her spine.
Inexplicably, her eyes drifted toward the beautiful boy not far away—Mina.
He nodded at her politely, and she instantly turned red and shy like a proper good girl.
Hana Yurukawa blinked and glanced around.
Wait a minute...
Was her bestie… catching feelings?
