Miss Tamayo, a talented researcher

"In terms of personality, Yuki Ieiri is highly self-centered. He acts with himself as the anchor, rarely considering—or even outright ignoring—the perceptions of others."

"Yet, strangely enough, when interacting with people, he creates an illusion, a peculiar sense of affinity in whoever he meets."

"Whether they are human or otherwise."

/

In the Gojo training grounds.

Four teenagers were sprinting across the field. They had split into two teams for a mock battle: Itadori and Ieiri against Fushiguro and Kugisaki.

"Kugisaki!"

Megumi Fushiguro’s gaze sharpened. "Take out Ieiri first."

"Got it!"

Although Nobara Kugisaki had only recently enrolled, much like Itadori, she had spent her time in the countryside training in jujutsu under her grandmother. Her control over cursed energy was formidable, and her martial arts skills were no less impressive.

"Straw Doll Technique…!"

Before the cursed-energy-infused nail could even trigger its effect, Kugisaki found herself immobilized. Three golden threads of cursed energy had bound her before she even realized it!

Those three golden "cords" were connected to Ieiri’s index, middle, and ring fingers. With a sharp pull from his left hand and a cross-pull from his right, he tightened them.

It was [Binding]!

One of the techniques of the Cursed Talismans.

Yuji Itadori’s praise was cut short as his expression shifted; he saw Megumi Fushiguro feint an attack, only to dash past him.

Fushiguro had completely ignored him.

He was charging straight for Ieiri!

Yuji Itadori: "...Huh?!"

Though stunned for a moment, he reacted quickly and gave chase.

However, blocking his path was a now-unbound Nobara Kugisaki.

Fushiguro’s shikigami, Nue, was already unleashing a rapid assault right in front of Ieiri. Ieiri could not maintain [Binding] indefinitely, so he immediately switched to [Area of Effect].

"Itadori, you and Ieiri are essentially a mage and knight combo. If you want to win, you obviously have to 'take out' the high-damage mage first!"

Kugisaki grinned, pouring cursed energy into her long nail. The "Hairpin" move of her Straw Doll Technique could trigger a large-scale explosion.

This was her trump card!

On the other side.

"Whoosh—"

Cursed talismans emerged from Yuki Ieiri’s pockets, guided by his cursed energy as he thrust them forward.

A circular halo instantly appeared beneath Megumi Fushiguro’s feet, followed by a pillar of fire shooting into the sky!

In the blink of an eye, Fushiguro burst through the thick fog. Simultaneously, his black Divine Dog coordinated perfectly, lunging toward Ieiri to snap at his pockets and devour his supply of talismans.

Ieiri sensed the movement.

"[Repel]!"

"Boom—"

The fluctuations of the boys' cursed energy surged throughout the arena. With each strike, a dense lingering residue was left behind at the point of impact.

Though it was just a practice session, no one was holding back. The training ground was completely enveloped in the billowing remains of their cursed energy.

Until a bell rang.

Everyone instinctively stopped.

Yuji Itadori and Fushiguro, who had been locked in a close-quarters combat exchange, landed from mid-air one after the other.

"Phew, time flies."

Rest time.

Yuji Itadori wiped the sweat from his brow, then suddenly remembered something. "Ieiri, the cooldown should be over. You can summon a shikigami again, right?"

Yuki nodded.

Since one shouldn't drink water immediately after intense exercise, a servant of the Gojo family offered clean towels to help the teenagers wipe the sweat from their faces.

"Thank you."

With the training over, Yuki Ieiri let out a sigh of relief and finally had the time to pay attention to the comments floating in the air.

The comments weren't always there—they disappeared from time to time. After observing for a while, Yuki had figured out the pattern:

They only appeared when there was a significant plot development.

Unbeknownst to everyone, these comments provided him with a wealth of information.

And so, he had developed a new function—

/

Fishing for comments.

For instance, right now, the teenagers were sitting cross-legged, waiting for their heart rates to normalize.

Naturally, this was the time for conversation.

Yuki Ieiri pondered and said, "I'm thinking of trying to summon a cursed spirit other than Muzan."

Perhaps because his technique awakened late, he only had a vague understanding of it.

[?!]

[Wait, so he can summon more than just the Scum Boss?!]

[I'm so excited I could rub my hands together! Since it's a brand new project, will they bring in a crossover from Bungo Stray Dogs?]

[No Longer Human, Upon the Tainted Sorrow, Do Not Die, Ultra-Deduction—if all four of those were gathered in the Jujutsu Kaisen world, I can't even imagine how explosive that would be.]

[But Yuki can only summon one at a time, right? And what if it's restricted to Demon Slayer?]

[Then it's still the Scum Boss.]

[Muzan is a cursed spirit in this world. He still hates sunlight, but he won't die.]

[Which means his greatest weakness has been eliminated. He’s truly overpowered.]

"Why not just keep summoning 'Muzan'?" Yuji Itadori asked.

Because they shared a body, Itadori could always hear Sukuna’s insatiable desire for his friend, Ieiri.

Sukuna was constantly coveting his friend's body.

This made Itadori feel uneasy. He wanted Sukuna to give up, but he couldn't defeat him. Summoning Muzan would provide an extra layer of security.

Yuki Ieiri, unaware of Itadori's internal struggle, said, "It gets boring if I always summon the same cursed spirit, doesn't it?"

Besides—people are always fickle.

Yuki Ieiri rested his chin on his palm and thought.

Of course, Muzan was special.

Even though Muzan had a terrible temper, he was beautiful to look at. And as the first cursed spirit Yuki had ever summoned, he held a unique status.

After hearing his reasoning, Megumi Fushiguro: "...?"

The sense of déjà vu was quite strong...

"Of course I love you."

"You are special."

—Ieiri, don't be a scumbag!

Hearing this, Kugisaki seemed to have found a kindred spirit and raised her hand. "I get it. It's like the new season's clothes; you need regular updates to keep things exciting."

She offered an example: "Pajamas, for instance, are the most special of all."

"The longer you wear them, the more they fit your skin, the more comfortable they feel."

Megumi Fushiguro: "...?"

He felt that actually made sense.

But something felt wrong.

[The formula is set: Muzan equals pajamas.]

[No way! Is Muzan really going to be benched just like that?]

[Help, I can't stop laughing whenever I see the phrase "just like that"...]

[Given Muzan's foul temper... if he’s really sealed for two weeks, he’s going to go crazy. Literally crazy.]

[He’s the most petty person ever.]

[Yuki, danger!!]

[If my "wife" wants to summon a new lover, I'm all for it. Can't wait!]

Yuki chuckled. There was no helping it; human nature is fickle. What could he do?

And how would Muzan react in his rage?

Would he... tear off that mask of his?

He was truly looking forward to it.

Yuki Ieiri changed the subject and proposed a hypothesis:

"The maximum duration a summoned cursed spirit can remain is two weeks, but that doesn't mean I have to wait two weeks to summon a new one, right?"

Fushiguro was startled, then immediately understood what he meant: "...You mean?"

The technique’s cooldown was two hours, and there were many two-hour blocks in a day.

Yuki Ieiri nodded, held up a finger, and smiled. "Perhaps I could use this to research the feasibility of summoning multiple cursed spirits in a single day?"

Itadori stood up. "Then I'll go call the teacher..."

/

Speak of the devil. At the main entrance, a tall figure stood with his head held high:

"The handsome and dashing Gojo-sensei has heard the calls of his cute students and makes a dazzling entrance!"

Itadori greeted him excitedly. "Gojo-sensei, you're back from your business trip!"

The white-haired teacher, whom they hadn't seen for a few days, exuded his usual frivolous yet reliable aura. His pink lips curled slightly. "In the few days I was gone, you've all made significant progress!"

"Especially Yuki and Yuji. Your cursed energy has become much more refined." His Six Eyes saw everything clearly.

"As expected of my students!"

o(￣▽￣)d

Gojo Satoru paused, remembering something.

"Oh, right, Yuki, your school uniform is ready. I had someone put it in your room."

Problem students usually wore white uniforms.

However, Gojo Satoru thought that color looked terrible with Yuki Ieiri’s design, so the final version was black, just like Fushiguro’s.

A pure black set, including a sleeveless top, cargo pants, combat boots, and a special belt with small pouches for categorized talismans and small cursed tools.

Practicality had been fully considered.

And it was incredibly stylish!

Yuki Ieiri thanked him.

Gojo Satoru stroked his chin and stated his purpose.

"By the way, I have a small mission here. Why don't we let Yuki have some real combat experience to warm up?"

"It’s not very dangerous. It involves word spirits. It’s the perfect time for the second-year seniors to take you along."

[Word spirits? It has to be Toge Inumaki, right?!]

[Can't wait! So excited!]

"Oh, Sensei, could you do me a favor?" Yuki Ieiri called out to Gojo Satoru, who was preparing to return to his room to finish off his souvenirs—a pile of sweets.

Gojo Satoru: "What is it?"

Yuki Ieiri explained his idea.

"I'm worried that any newly summoned cursed spirit might be powerful and uncontrollable, so I need you to be there."

Gojo Satoru preened. "You’ve definitely come to the right person, because—"

"I am the strongest jujutsu sorcerer, after all!"

The white-haired teacher said, full of spirit, "Go ahead and summon with confidence!"

Yuki Ieiri nodded. "Okay."

At the same time, he motioned for Fushiguro and the others to step back.

As the summoning technique was activated once more, space began to distort.

From the pitch-black void, a figure emerged. The first thing they saw was the hem of a purple garment.

Everyone held their breath, and the expansive training ground fell into complete silence.

Soft, measured footsteps stopped in front of them.

A woman stepped out from the void.

She had long black hair styled in a bun, eyes like pale purple mist, and was wearing a kimono in a matching hue.

[?!]

[Ahhhhhh!]

[It's the genius of the scientific world, Lady Tamayo!]

[A genius, indeed. Can't argue with that, since she really is a demon_(:з」∠)_]

[Can someone give me a recap? I don't remember the plot.]

[Lady Tamayo, the demon who broke free from Muzan's curse.]

[She then used her own efforts to develop the lethal poison that decided the final battle.]

[Hiss!]

[What if she tried researching the cursed spirit?]

[Wait, cursed spirits have lingering traces, right? Won't the Scum Boss recognize Lady Tamayo's traces? Given his personality...]

[?!]

[Yuki, you're in even greater danger!]

[If you're going to fight, make sure you do it in the bedroom!]
