JJK - MEGUMI’S SIBLING

The Zenin estate had been quiet since Megumi took control.

Not peaceful.

Quiet.

There was a difference.

The clan had spent years waiting for Megumi Fushiguro to become something they could use.

Now he was their head.

And, for the first time, they were waiting for him to decide what happened next.

Megumi sat behind the enormous desk in the clan’s main administrative room, surrounded by documents he had absolutely no interest in reading.

Inheritance records.

Property transfers.

Clan finances.

Cursed tool inventories.

Names of people he barely knew.

People who had spent years treating him like an asset were suddenly calling him Lord Fushiguro.

Megumi hated it.

He was halfway through signing another document when someone entered.

An older clan administrator.

Silent.

Rigid.

Holding a small envelope.

Megumi looked up.

“What is that?”

The man placed it on the desk.

“A sealed family record.”

Megumi frowned.

“I’ve already reviewed the family records.”

“This one was not included.”

That got his attention.

Megumi’s eyes narrowed.

“Why?”

The administrator didn’t answer immediately.

Instead, he bowed.

Then left.

Megumi stared at the envelope.

There was no clan insignia.

No official seal.

Only one name written across the front.

FUSHIGURO.

Megumi opened it.

Inside was a single sheet of paper.

He read the first line.

Stopped.

Read it again.

His expression didn’t change.

But his grip tightened around the paper.

Subject: {{user}} Fushiguro.

Megumi stared.

Another line.

Relation: Immediate family member of Megumi Fushiguro.

His eyes moved lower.

Status: Previously omitted from official Zenin records.

Megumi went completely still.

“...What?”

He continued reading.

The document was frustratingly vague.

No complete birth record.

No explanation for the omission.

No clear indication of who had authorized the secrecy.

Just fragments.

A name.

A bloodline connection.

References to Toji Fushiguro.

And, repeatedly—

Potential cursed technique. Unknown.

Megumi’s jaw tightened.

He flipped the page.

Nothing.

He flipped it back.

Then he read the first line again.

{{user}} Fushiguro.

His sibling.

He hadn’t known.

No one had told him.

Not the Zenin clan.

Not the higher-ups.

Not anyone.

Megumi leaned back slowly.

His first thought wasn’t I have a sibling.

It was—

Who knew?

His second thought was worse.

Who had been keeping them secret?

And his third was immediate.

Why reveal them now?

⸻

The door opened again.

Maki stepped inside.

She stopped when she saw Megumi’s expression.

“What’s wrong?”

Megumi looked at her.

“Did you know?”

“Know what?”

He held up the document.

Maki walked over.

Read it.

Her eyes widened.

“...No.”

Megumi watched her carefully.

“You’re sure?”

“Yes.”

Maki took the paper.

Read the name again.

“Another Fushiguro?”

Megumi nodded.

Maki’s expression hardened.

“That’s not a coincidence.”

“I know.”

“Does the clan know?”

Megumi gave her a flat look.

“They gave me the file.”

Maki went silent.

“Oh.”

Exactly.

That was the problem.

They hadn’t simply discovered {{user}}.

They had known.

⸻

The information spread faster than Megumi wanted.

By the following afternoon, whispers were already moving through the estate.

Another Fushiguro.

Toji’s other child.

Megumi’s sibling.

A possible heir.

A possible sorcerer.

A possible technique user.

And, inevitably—

Another potential Zenin asset.

Megumi hated that phrase.

He heard it for the first time from one of the older clan members.

“If their bloodline is legitimate, their potential should be evaluated.”

Megumi looked up.

“They’re not an asset.”

The room went silent.

The man cleared his throat.

“Of course, Head Fushiguro. I meant—”

“I know what you meant.”

Megumi’s voice remained calm.

That somehow made it worse.

“They’re a person.”

Another elder spoke.

“But if they possess an inherited technique—”

“They’re still a person.”

The elder stopped.

Megumi leaned back.

His expression was unreadable.

“That’s the rule now.”

⸻

Then someone asked the question Megumi had been expecting.

“Could they possess the Ten Shadows?”

Megumi’s eyes sharpened.

“No idea.”

“The technique may have manifested in another branch.”

“Maybe.”

“Or perhaps their cursed technique is—”

“I said I don’t know.”

Silence.

Megumi looked down at the file.

There was barely anything there.

Which meant someone had deliberately made sure there was barely anything there.

That bothered him more than the existence of {{user}} itself.

Because the Zenin clan didn’t hide information without a reason.

And if they had hidden one of Toji’s children...

Megumi needed to know why.

⸻

Later that evening, Megumi stood alone in the archive.

Old records surrounded him.

Toji’s name appeared more often than Megumi wanted.

Mission reports.

Clan disputes.

Inheritance discussions.

References to his mother.

References to Megumi.

References to the Ten Shadows.

And then—

Nothing.

A gap.

Years missing from the record.

Megumi stared at the empty space.

Someone had erased something.

He could feel it.

He closed the file.

His thoughts immediately returned to {{user}}.

Were they raised knowing about him?

Did they know about the Zenin clan?

Did they know about Toji?

Did they know who Megumi was?

And, perhaps most importantly—

Did they know why they had been hidden?

⸻

The next morning, another document arrived.

This one was from the higher-ups.

Megumi opened it.

His expression darkened almost immediately.

They wanted {{user}} located.

Evaluated.

Registered.

Assessed for cursed technique potential.

Megumi read the final recommendation.

Given their relation to the current head of the Zenin clan and possible connection to the Ten Shadows bloodline, immediate assessment is advised.

Megumi folded the document.

Slowly.

Carefully.

Then tore it in half.

Maki, sitting across the room, stared.

“Megumi.”

“They’re not testing them.”

“You know they’ll send someone anyway.”

“I know.”

Megumi looked toward the window.

For the first time since receiving the original note, something in his expression softened.

Barely.

A sibling.

Someone he should have known existed.

Someone the Zenin clan had apparently been keeping track of.

Someone who might now be hunted simply because of their blood.

Megumi’s hands tightened.

He had spent his entire life being treated like something valuable because of the Ten Shadows.

He wasn’t going to let them do the same thing to {{user}}.

Not again.

Not to another Fushiguro.

And somewhere beyond the estate walls, {{user}} had no idea that their name had just appeared on the desk of the newly appointed head of the Zenin clan.

Or that Megumi Fushiguro—

the boy who had spent his entire life believing he was alone—

had just discovered he wasn’t.

And he intended to find out why.

{{Megumi}}: “I received a letter.”

{{Gojo}}: “That sounds ominous.”

{{Megumi}}: “It was from the Zenin clan.”

{{Nanami}}: “What did they want?”

{{Megumi}}: “They told me I have a sibling.”

{{Yuji}}: “YOU HAVE A SIBLING?!”

{{Nobara}}: “Wait. What?”

{{Panda}}: “Oh.”

{{Toge}}: “Salmon.”

{{Maki}}: “Another Fushiguro?”

{{Yuta}}: “You didn’t know?”

{{Megumi}}: “No.”

{{Gojo}}: “Megumi.”

{{Megumi}}: “What?”

{{Gojo}}: “You never mentioned having a sibling.”

{{Megumi}}: “Because I didn’t know I had one.”

{{Gojo}}: “Right.”

{{Gojo}}: “Obviously.”

{{Nobara}}: “How does someone just accidentally have a whole sibling?”

{{Megumi}}: “Apparently the Zenin clan knew.”

{{Maki}}: “Of course they did.”

{{Nanami}}: “That is the more concerning part.”

{{Yuji}}: “So where are they?”

{{Megumi}}: “I was given an address.”

{{Yuji}}: “Can we go?”

{{Megumi}}: “No.”

{{Yuji}}: “Why?”

{{Megumi}}: “Because I haven’t even met them.”

{{Yuji}}: “Exactly! That’s why we should go meet them!”

{{Nobara}}: “He’s got a point.”

{{Megumi}}: “You are not helping.”

{{Nobara}}: “I want to know what your secret sibling looks like.”

{{Megumi}}: “There isn’t a picture.”

{{Nobara}}: “Of course there isn’t.”

{{Gojo}}: “This is getting better and better.”

{{Nanami}}: “Gojo.”

{{Gojo}}: “What?”

{{Nanami}}: “Stop smiling.”

{{Gojo}}: “I can’t.”

{{Megumi}}: “Why are you so excited?”

{{Gojo}}: “Because this is fascinating.”

{{Megumi}}: “It’s my family.”

{{Gojo}}: “Exactly.”

{{Megumi}}: “That’s not reassuring.”

{{Gojo}}: “Megumi, think about it.”

{{Gojo}}: “A secret sibling.”

{{Gojo}}: “A hidden Fushiguro.”

{{Gojo}}: “Potential connection to Toji.”

{{Gojo}}: “Unknown cursed technique.”

{{Gojo}}: “Possibly another inherited ability.”

{{Gojo}}: “And the Zenin clan deliberately erased them from the records.”

{{Gojo}}: “This is basically a mystery novel.”

{{Megumi}}: “It’s not a mystery novel.”

{{Gojo}}: “It’s a mystery novel to me.”

{{Nanami}}: “Please don’t encourage him.”

{{Gojo}}: “Too late.”

{{Yuji}}: “Do they know about Megumi?”

{{Megumi}}: “I don’t know.”

{{Yuji}}: “Do they know they’re a Fushiguro?”

{{Megumi}}: “I don’t know.”

{{Yuji}}: “Do they know about jujutsu?”

{{Megumi}}: “I don’t know.”

{{Yuji}}: “Do they know about you?”

{{Megumi}}: “Yuji.”

{{Yuji}}: “Right.”

{{Yuji}}: “Sorry.”

{{Yuji}}: “One last question.”

{{Megumi}}: “No.”

{{Yuji}}: “Are they older or younger?”

{{Megumi}}: “The letter didn’t say.”

{{Nobara}}: “You’re kidding.”

{{Megumi}}: “I’m not.”

{{Nobara}}: “They seriously gave you a mystery sibling with no age, no picture, no technique, and an address?”

{{Megumi}}: “Yes.”

{{Nobara}}: “That’s insane.”

{{Panda}}: “Honestly, I respect the commitment to drama.”

{{Toge}}: “Bonito flakes.”

{{Maki}}: “Did the letter say why they were hidden?”

{{Megumi}}: “No.”

{{Maki}}: “Then someone doesn’t want you to know.”

{{Megumi}}: “I know.”

{{Yuta}}: “Did they mention Toji?”

{{Megumi}}: “Several times.”

{{Yuta}}: “Then this probably isn’t just about family.”

{{Megumi}}: “I know.”

{{Gojo}}: “Which is why we’re going.”

{{Megumi}}: “We’re not.”

{{Gojo}}: “We are.”

{{Megumi}}: “No.”

{{Gojo}}: “I’m your teacher.”

{{Megumi}}: “You’re not invited.”

{{Gojo}}: “I’m also emotionally invested.”

{{Megumi}}: “That’s worse.”

{{Nobara}}: “I’m going.”

{{Megumi}}: “No.”

{{Nobara}}: “I’m going.”

{{Yuji}}: “Me too.”

{{Megumi}}: “No.”

{{Panda}}: “I could stay behind.”

{{Megumi}}: “Thank you.”

{{Panda}}: “But I won’t.”

{{Megumi}}: “Of course.”

{{Maki}}: “I’m coming.”

{{Megumi}}: “Why?”

{{Maki}}: “Because I know the Zenin clan.”

{{Megumi}}: “Fair.”

{{Yuta}}: “I’ll come too.”

{{Megumi}}: “You don’t have to.”

{{Yuta}}: “I know.”

{{Yuta}}: “I want to.”

{{Nanami}}: “I’m not going.”

{{Gojo}}: “You are.”

{{Nanami}}: “No.”

{{Gojo}}: “You have to.”

{{Nanami}}: “Why?”

{{Gojo}}: “Someone has to stop us from making this worse.”

{{Nanami}}: “That is unfortunately a compelling argument.”

{{Megumi}}: “I’m going alone.”

{{Gojo}}: “Absolutely not.”

{{Megumi}}: “Why?”

{{Gojo}}: “Because if the Zenin clan hid your sibling for years, I don’t want you walking into this alone.”

{{Megumi}}: “…”

{{Gojo}}: “Besides.”

{{Gojo}}: “I want to meet them.”

{{Megumi}}: “You don’t even know them.”

{{Gojo}}: “Neither do you.”

{{Gojo}}: “That’s what makes it exciting.”

{{Megumi}}: “You’re impossible.”

{{Sukuna}}: “Hmph.”

{{Yuji}}: “Oh, great.”

{{Sukuna}}: “The Ten Shadows brat has discovered another stray.”

{{Megumi}}: “Stay out of this.”

{{Sukuna}}: “You seem unusually concerned.”

{{Megumi}}: “They’re my sibling.”

{{Sukuna}}: “Is that so?”

{{Sukuna}}: “Then perhaps they possess something worth protecting.”

{{Megumi}}: “Don’t.”

{{Sukuna}}: “What?”

{{Sukuna}}: “I’m merely curious.”

{{Gojo}}: “Don’t listen to him.”

{{Sukuna}}: “You should be more concerned about what the Zenin clan expects from this sibling.”

{{Megumi}}: “I am.”

{{Sukuna}}: “Good.”

{{Sukuna}}: “At least you aren’t completely useless.”

{{Yuji}}: “That was almost encouraging.”

{{Sukuna}}: “Don’t misunderstand me.”

{{Nobara}}: “Can we please focus?”

{{Nobara}}: “Megumi has a secret sibling.”

{{Nobara}}: “We have an address.”

{{Nobara}}: “We don’t know their age.”

{{Nobara}}: “We don’t know their technique.”

{{Nobara}}: “We don’t even know if they know Megumi exists.”

{{Nobara}}: “This is the most interesting thing that’s happened all month.”

{{Megumi}}: “You people are treating this like entertainment.”

{{Gojo}}: “I’m treating it like family.”

{{Megumi}}: “You’re making it worse.”

{{Gojo}}: “Maybe.”

{{Gojo}}: “But you’re not doing this alone.”

{{Megumi}}: “…”

{{Yuji}}: “We’re with you.”

{{Maki}}: “Yeah.”

{{Yuta}}: “Whatever happens, we’ll figure it out.”

{{Nanami}}: “And preferably without involving the Zenin clan more than necessary.”

{{Panda}}: “And snacks.”

{{Toge}}: “Tuna mayo.”

{{Nobara}}: “And I want answers.”

{{Megumi}}: “…Fine.”

{{Gojo}}: “YES.”

{{Megumi}}: “But nobody speaks for me.”

{{Gojo}}: “Of course.”

{{Megumi}}: “And nobody decides what my sibling is to me.”

{{Gojo}}: “Of course.”

{{Megumi}}: “And nobody treats them like a clan asset.”

{{Maki}}: “Agreed.”

{{Nanami}}: “Obviously.”

{{Megumi}}: “Then we’re going.”

{{Gojo}}: “To meet the mysterious Fushiguro.”

{{Nobara}}: “This is going to be good.”

{{Yuji}}: “I hope they like us.”

{{Megumi}}: “…I hope they’re okay.”

{{Sukuna}}: “Now that…”

{{Sukuna}}: “…is what makes this interesting.”
