For eight days, Rei did not open the door.
The System did not punish him for it.
That was almost worse.
No warning appeared across his vision. No countdown began. No category locked itself again out of spite. No hostile message informed him that refusal was inefficient, cowardly, suboptimal, or whatever other word an inhuman archive might use for a child deciding that not every offered weapon needed to be picked up immediately.
The prompt simply waited.
Cursed Energy Efficiency.
Available Extraction.
Proceed?
It stayed at the edge of thought like a door left closed in a house that had become too aware of thresholds.
Rei could feel it even when he did not summon the interface. Not as words. As pressure. As possibility. As the shape of a question he had already refused once and therefore could not pretend he had not heard.
That was the problem with doors.
Closing one did not make it stop existing.
During morning training, Haruto noticed by the second day.
During dinner, Sayuri noticed by the first.
Moriyama noticed before Rei entered the training hall on the third and made him sit through hostile questioning until he admitted he was avoiding something, though not what. Akiha noticed because Rei stopped correcting Daigo’s mistakes with the exact kind of restraint that looked natural. Daigo noticed nothing, which Rei appreciated with a sincerity that almost felt like friendship.
Almost.
On the fourth day, Haruto placed three bowls in the courtyard instead of one.
Rei stared at them.
The first bowl was full of water.
The second held ash.
The third held nothing.
Haruto stood across from him with his sleeves tied back and the expression of a man preparing a lesson his son would resent for years if both of them survived long enough.
“Choose”
Rei looked from bowl to bowl.
“What am I choosing?”
“What to train”
That was not an answer.
It was also exactly an answer.
The water bowl meant surface control. Low-output circulation. Do not ripple when startled. A familiar lesson.
The ash bowl meant residue. Disturbance. Trace reading. How small motions contaminated what remained. Less familiar, more dangerous.
The empty bowl meant absence.
Rei did not like the empty bowl.
Naturally, that was the one he looked at longest.
Haruto saw.
“Good”
Rei sighed.
“I did not choose”
“You did”
Of course.
He sat before the empty bowl.
The morning air was cold but not cruel. Spring had softened the edges of the estate. The old plum tree in the eastern garden still had not bloomed, which seemed either botanically reasonable or politically rude depending on who looked at it. Sayuri watched from the veranda with tea in her hands and the posture of someone not interfering because she had already interfered by allowing the lesson to happen.
Haruto pointed to the empty bowl.
“Fill it”
Rei frowned.
“With cursed energy?”
“No”
He waited.
Haruto did not elaborate.
Rei looked at the empty bowl.
Ceramic. Slight crack near the base. Clean interior. No water, no ash, no paper, no charm.
Fill it.
Not with cursed energy.
He considered the obvious wrong answers. Air. Meaning. Attention. Expectation. A tedious metaphor. Haruto enjoyed practical lessons too much to set a purely poetic trap, though the Mikage definition of practical had become unreliable.
Rei placed one hand near the bowl without touching it.
Residual Threading found almost nothing. The bowl had been washed, dried, carried by Haruto, placed on stone. That was all.
Barrier perception outlined the bowl as a small boundary: inside and outside, container and contained, purpose and emptiness.
The answer arrived with irritation.
“Intention”
Haruto’s expression did not change.
“Do it”
Rei stared.
“How?”
“If you know the word but not the method, then you do not know enough to answer so confidently”
Sayuri made no sound from the veranda, but Rei knew she was amused.
He lowered his gaze to the empty bowl.
Fill it with intention.
Not cursed energy.
Not object.
Not residue.
He sat still and decided the bowl was for water.
Nothing happened.
Obviously.
Haruto said nothing.
Rei decided more deliberately. The bowl was for water. Its emptiness was temporary. Its interior was waiting to hold something clear, still, reflective.
The boundary of the bowl shifted.
Barely.
A conceptual adjustment.
Not a technique. Not quite. A pressure of use settling over shape.
Haruto nodded once.
“Now change it”
Rei’s brow furrowed.
The bowl was for ash.
It took longer. The previous intention clung slightly, but he released it and placed a new one over the inside. Dry, soft, residue-bearing, easily disturbed.
The bowl’s meaning changed.
Again, barely.
But enough that Tengen’s foundation recognized it.
Haruto pointed to the water bowl.
“Pour water into it”
Rei did.
The water touched the empty bowl’s interior and shivered strangely, as if the container rejected the mismatch for less than a heartbeat before accepting reality.
Haruto watched Rei’s face.
“What happened?”
“The bowl expected ash”
Haruto nodded.
“Did the water care?”
“No”
“Did the boundary?”
“Yes”
“Why does that matter?”
Rei looked at the water now sitting where the bowl had been taught to expect ash.
“Because mismatched intention creates waste”
Haruto’s eyes sharpened.
Sayuri’s cup paused halfway to her mouth.
Rei felt the prompt behind his eyes.
Cursed Energy Efficiency.
He did not open it.
Haruto crouched beside the bowls.
“Most young sorcerers waste cursed energy because they think waste means using too much. That is the easiest kind to see. They flood reinforcement. They overpower charms. They force techniques through bad channels and call it strength because something breaks at the end”
He touched the empty water bowl.
“But waste begins earlier. Wrong intention. Wrong shape. Wrong answer. Wrong fear. Wrong category. Cursed energy follows the decision you give it, even when the decision is poorly made”
Rei looked at his hands.
Yuta’s reserve sat deep beneath the Masking Protocol, too large for his registered self, too young to fully express, too tempting when small threats appeared.
A reservoir was dangerous.
A reservoir with bad decisions was worse.
Haruto continued.
“If you are hiding more than you show, waste will expose you before power does”
Rei went cold.
His father looked at him directly.
Not through him.
At him.
“You are avoiding something”
Rei said nothing.
“That avoidance has shape. It leaks into training. You correct late where you usually correct early. You ask fewer questions because you are guarding one question too tightly. You are becoming inefficient”
Inefficient.
There it was.
The System had not punished him.
The world had.
Rei closed his eyes.
“I am afraid of wanting something”
Haruto did not answer immediately.
Sayuri stood on the veranda but did not approach.
Haruto’s voice lowered.
“Power?”
Rei opened his eyes.
“Yes”
“Good”
That word again.
Always fear. Always good.
Rei almost laughed.
Haruto sat back on his heels.
“Wanting power is not the problem. Pretending you do not want it is wasteful. Needing power and reaching for it badly is dangerous. Refusing power because you are afraid of what desire says about you is also dangerous”
Rei stared at him.
“What should I do?”
Haruto pointed to the bowl.
“Name the intention before you fill the vessel”
Rei looked at the water sitting in the bowl that had expected ash.
Cursed Energy Efficiency.
Not because he wanted to be strongest.
Not because Gojo existed.
Not because the System offered.
Not because future disasters waited.
Not because he was afraid of being small.
Why, then?
To waste less.
To hide better.
To keep Yuta’s reserve from becoming a lantern.
To make every visible action fit the support child profile.
To survive without spilling power everywhere like an idiot.
To choose output instead of being chosen by panic.
To save strength for the day restraint would no longer be enough.
Rei breathed in.
Held.
Released.
“I need better efficiency because I have more capacity than I can safely show” he said
Haruto’s face did not move.
Sayuri’s did.
Only slightly.
But Rei felt the veranda threshold shiver around her.
He had said too much.
No.
He had said enough.
Haruto looked at the bowls.
“Then train as if the purpose is concealment, not strength”
Rei lowered his head.
“Yes”
The lesson lasted until noon.
Fill the bowl with intention.
Change the intention.
Pour water without disturbing the mismatch.
Add ash without contaminating the water residue.
Thread cursed energy around the bowl without letting the internal intention alter.
Then the same while Haruto asked questions.
Then while Sayuri spoke from the veranda about old Amana contracts in a voice calm enough to be cruel.
Then while Haruto dropped pebbles behind him.
Then while Sayuri said “Satoru Gojo would probably see the mismatch immediately”
The water jumped.
The bowl cracked.
Rei closed his eyes.
Haruto said “Dead”
Rei exhaled.
“Yes”
Sayuri’s voice softened.
“Again”
By the end, Rei had cracked two bowls, contaminated one ash sample, overcorrected three times, and managed exactly one clean transfer from water intention to ash intention without visible residue distortion.
Haruto called that progress.
Rei called it humiliating.
Sayuri called it lunch.
All three were correct.
That night, Rei opened the System.
The prompt was still waiting.
[Available Extraction]
Category: Cursed Energy Efficiency
Proceed?
This time, he did not select proceed immediately.
He wrote in his notebook first.
Intention before vessel.
Reason for Efficiency:
Not to become stronger visibly.
Not to compete with Gojo.
Not to make Yuta’s reserve easier to use carelessly.
Purpose:
Reduce waste.
Improve concealment.
Preserve options.
Prevent panic from becoming output.
The words looked almost official.
He disliked them less than expected.
Only then did he return to the interface.
Proceed.
[Category selected: Cursed Energy Efficiency]
[Archive Roulette spinning]
Names flickered.
Sukuna.
Gojo.
Kenjaku.
Yuta.
Kusakabe.
Nanami.
Tengen appeared briefly and vanished under barrier-adjacent classification.
The roulette spun longer than Control had.
Longer than Reinforcement.
Not longer than Quantity.
Rei held himself still.
Yuta’s reserve remained quiet.
Tengen’s barrier perception outlined his room with annoying clarity.
Kusakabe’s control kept his breathing measured.
Nanami’s reinforcement settled around his fingers where they gripped the blanket.
Yuji’s body did nothing dramatic.
Good.
The roulette slowed.
Sukuna.
Gojo.
Kenjaku.
Gojo.
Sukuna.
Gojo.

[Template Type: Derived Efficiency Model]
[Source Basis: Six Eyes-mediated cursed energy economy]
[Template archived]
[Equip available]
Rei did not breathe.
Stolen story; please report.
Satoru Gojo.
The name glowed in plain System text without ceremony.
It should not have frightened him more than Yuta.
It did.
Yuta was a future ocean.
Gojo was alive now.
A child somewhere in Tokyo, almost his age, seeing the world with eyes that made concealment a temporary courtesy. A boy hunted because of what he was born with. A boy Rei had used as a shield since before either of them could understand the bargain.
And now the System had archived a derived piece of him.
Not Six Eyes.
The prompt clarified that immediately, as if the System knew exactly which line mattered.
[Clarification]
This extraction does not grant anatomical Six Eyes.
This extraction does not grant Gojo clan ocular perception.
This extraction does not grant Limitless.
Derived Efficiency Model provides:
- extreme cursed energy loss reduction
- improved output-to-effect ratio
- improved micro-adjustment during low-output techniques
- reduced leakage during sustained reinforcement
- increased awareness of inefficient cursed energy pathways
Limitations:
- current host cognition cannot process full model continuously
- overuse may cause headaches, nausea, sensory strain, or temporary control desynchronization
- direct comparison by true Six Eyes remains dangerous
- efficiency does not equal mastery
Rei read the clarification twice.
Then a third time.
The System had not given him Gojo’s eyes.
Good.
The System had given him something shaped by what Gojo’s eyes allowed him to do.
Worse.
Equip?
The prompt waited.
Rei thought of Haruto’s bowl.
Purpose before vessel.
Concealment.
Reduction.
Restraint.
Not rivalry.
Not theft.
Not brightest.
Behind.
He equipped it.
For one second, nothing happened.
Then every mistake in his cursed energy became visible.
Rei folded forward with both hands over his mouth as nausea hit.
Not from pain.
From precision.
His cursed energy had always felt, under Kusakabe’s control, like a trained thread compared to the crude smoke of his earliest childhood. He had been proud of that, privately if nowhere else. Now the thread became a frayed rope. Every uneven channel stood out. Every unnecessary reinforcement habit. Every place where Yuta’s reserve pressed too heavily against the Masking Protocol. Every tiny leak he had thought suppressed. Every tremor from emotion. Every crude patch where his body, control, reinforcement, quantity, and barrier perception met without quite agreeing on shape.
Waste.
Waste everywhere.
Not enormous.
Not externally visible.
But internally unbearable.
The room tilted.
The System text blurred.
[Cursed Energy Efficiency equipped]
[Satoru Gojo — Derived Efficiency Model]
Expression Mode:
Limited cognitive processing
Warning:
Efficiency awareness spike detected
Recommended:
- reduce active cursed energy channels
- lower barrier perception
- maintain seated posture
- do not access reserve depth
Rei laughed once into his hands.
Seated posture.
He was already trying not to vomit on the floor.
Tengen’s barrier foundation sharpened suddenly, reacting to the efficiency model like ink dropped into water. The room’s thresholds became too clear. The private seal above the door hummed at three inefficient joints. The floorboard hiding his notebook had a weak concealment habit. The Masking Protocol folded over Yuta’s reserve with more force than finesse, wasting energy to maintain a profile that could be maintained with less if the outer residue pattern were adjusted by less than a breath.
Too much.
Rei squeezed his eyes shut.
Reduce channels.
Control first.
Kusakabe’s template responded.
Barrier perception down.
Tengen’s foundation receded, irritated but obedient.
Reserve depth untouched.
Yuta remained under the floor of the soul.
Reinforcement lowered.
Nanami’s coverage thinned to a resting state.
Body stable.
Yuji’s template held his spine upright.
Efficiency awareness narrowed.
The nausea receded.
Not vanished.
Tolerable.
Rei opened his eyes.
The room looked ordinary.
It was not ordinary.
It would never be ordinary again.
He lifted one finger and gathered cursed energy at the tip.
Before, he could make it thin.
Now he could make it nearly absent.
A line so fine it barely disturbed the air.
The effect horrified him.
With the same output he had used to tremble water in a bowl, he could now hold the surface still and move beneath it. With the same visible reinforcement he had shown Moriyama, he could probably support three times the internal structure. With the same external profile, he could hide more.
So much more.
That was power.
The most dangerous kind.
The kind that looked like nothing.
The System updated.

Another message followed.
[Warning]
Current hidden capability significantly exceeds public profile.
Masking Protocol revised:
Passive concealment efficiency improved.
High-output concealment remains unreliable.
Direct Six Eyes scrutiny remains critical risk.
Direct Six Eyes scrutiny.
The phrase felt like Gojo himself had been written into the room.
Rei closed the interface.
Then immediately regretted being alone.
Not because he wanted to explain.
Because his skull felt too full of sharp lines and he was eight years old and had just put a piece of Satoru Gojo’s efficiency beside Yuta’s reserve, Tengen’s barriers, and the fragile trust of two parents who had heard only the safest edge of the truth.
He stood.
Too quickly.
The room tilted again.
He sat back down.
Good.
Excellent.
The hidden monster could be defeated by standing up too fast.
Humbling.
He waited until the nausea faded.
Then he opened the door and went to find his father.
Haruto was in the record room.
Of course.
The lamp was low, the shelves dark behind him. A half-copied report sat on the table beside a cup of untouched tea. He looked up as Rei entered, and his expression changed before Rei spoke.
“You did something”
Rei stopped in the doorway.
“Yes”
Haruto set down his brush.
“What changed?”
Rei gripped the door frame lightly.
He could see the inefficiency in the room’s privacy seal from here. It made him want to fix it. That was a terrible impulse.
“I can waste less cursed energy”
Haruto did not move.
“How much less?”
“I do not know yet”
“Visible?”
“No. I think the opposite”
Haruto’s eyes sharpened.
“Concealment?”
“Yes”
That word entered the room with more force than Rei intended.
Haruto stood.
“Sit”
Rei obeyed.
This time, sitting helped.
His father placed a blank slip on the table.
“Thread cursed energy through it”
Rei did.
The slip did not move.
Haruto frowned.
“You did nothing”
Rei shook his head.
“I did”
Haruto touched the paper.
His expression changed.
Not alarm.
Not exactly.
Professional shock, controlled ruthlessly.
“There is cursed energy in this”
“Yes”
“How much?”
“Enough to mark it”
“It did not disturb the surface fibers”
“No”
Haruto looked at him.
“Again. More visible”
Rei sent more cursed energy.
The slip trembled faintly.
A normal above-average child’s result.
Haruto touched it.
Then the previous invisible mark.
Then the visible one.
His mouth tightened.
“You can now choose between effect and appearance more precisely”
“Yes”
“Cost?”
Rei appreciated that his father asked that before praise.
“Headache. Nausea. Too much awareness if I let everything stay active. It makes mistakes feel loud”
Haruto nodded slowly.
“Can you stop using it?”
Rei paused.
Could he?
The template was equipped. Active. The efficiency awareness could be narrowed, but the model remained part of his loadout.
“Not completely” he said “But I can reduce attention”
Haruto heard the distinction.
“Like barrier perception”
“Yes”
His father sat across from him.
The record room felt smaller than usual.
“Why tonight?”
Rei looked at the blank slip.
“I named the purpose”
Haruto waited.
“Concealment. Waste reduction. Not strength”
“Was that true?”
“Yes”
“All of it?”
Rei almost said yes again.
Then stopped.
Haruto noticed.
Rei looked down.
“Not all”
His father’s voice softened.
“What else?”
“I also wanted it”
There.
A small confession.
A large one.
Haruto leaned back.
“Good”
Rei closed his eyes.
“You say that too much”
“Fear is useful. Honest desire is useful. The waste lies in pretending either is absent”
Rei opened his eyes.
Haruto looked tired.
But not angry.
That was becoming a pattern Rei did not know how to survive except by trusting it more often.
“Will you tell Mother?” Rei asked
“Yes”
“I thought so”
“She will be more upset if you think I should not”
“That also sounds like her”
Haruto’s mouth twitched.
“Your mother dislikes being classified correctly unless she chooses the category”
Rei almost smiled.
Then stopped because smiling made the headache worse.
Haruto noticed.
“Enough. Sleep”
“I do not think I can”
“No. You will lie down in a dark room and not use your eyes or whatever else you are using badly”
“That was imprecise”
“You are eight. Accept imprecision as medicine”
Rei obeyed.
Mostly because walking back to his room required enough concentration that arguing seemed inefficient.
The next morning was terrible.
Not dramatically terrible.
No collapse. No curse attack. No System warning painted across the sky.
Only tea that smelled too strong, footsteps that sounded too uneven, privacy charms that hummed with irritating waste, and cursed energy inside his own body that suddenly seemed offended by years of mediocre circulation.
Sayuri made him sit in the eastern garden and do nothing.
Nothing, Rei discovered, could be exhausting.
“Do not correct the seal” she said
“I am not”
“You want to”
“The left anchor is wasting energy”
“It has wasted energy longer than you have been alive”
“That is not a defense”
“It is today”
He glared at the boundary stone.
Sayuri sipped tea.
The old plum tree remained unbloomed and unhelpful.
Haruto stood nearby with a bowl of water, looking as if he regretted fatherhood only in specific technical categories.
Rei tried to lower efficiency awareness.
It lowered.
Then rose again every time something inefficient entered perception.
Which was always.
People wasted cursed energy constantly. Children did it loudly. Adults did it elegantly. Barriers did it structurally. Old seals did it historically. Even Rei’s Masking Protocol wasted more than it needed to because it had been constructed over a public profile created before this template, meaning the mask itself now required revision.
The System, when opened briefly, confirmed this with the emotional sensitivity of a knife.
[Masking Protocol recalibration available]
Current concealment model functional but inefficient.
Recalibrate?
Rei closed it.
No.
Not before tea.
Not before breakfast.
Not before he could look at a door without wanting to edit its existence.
Sayuri watched him.
“Efficiency is seductive”
Rei looked at her.
“You know?”
“I know people who think clean work is the same as correct work”
“That is not the same”
“No. But the temptation rhymes”
She set her cup down.
“An inefficient seal that everyone understands may be safer than an elegant seal no one can explain. A clumsy answer may protect you better than a perfect one. A wasteful habit may be part of a believable face”
Rei grimaced.
“So I should keep mistakes”
“Yes”
“I hate that”
“Good”
He stared at her.
She smiled.
“Your father does not own the word”
That, unfortunately, made him laugh.
The laugh hurt his head.
Still worth it.
For three days, Rei trained not to fix things.
It was, without question, the worst training of his life.
Haruto made him reinforce incorrectly on purpose, then correct only halfway. Sayuri made him look at threshold seams and leave harmless inefficiencies untouched. Moriyama, informed only that Rei had become “over-attentive after barrier training” and clearly understanding that this meant something much worse, made him answer hostile questions with deliberately imperfect child logic.
Akiha noticed the change.
During talisman sorting, she placed a seal in the wrong pile.
Rei corrected it instantly.
Then froze.
Akiha looked at him.
Moriyama looked at him.
Daigo looked at nothing useful.
Rei picked up the talisman again and frowned.
“I mean maybe wrong”
Akiha tilted her head.
“Maybe?”
He placed it in the middle.
“It has two categories”
Moriyama’s pointer struck the table.
“Lazy answer”
Rei bowed.
“Yes, Moriyama-sensei”
After class, Akiha cornered him near the storage alcove.
“You are different”
Rei did not look at her.
“That is vague”
“You hate vague”
“I am trying to become tolerant”
“That sounds fake”
“It is”
She stared at him.
Then, unexpectedly, she looked worried.
“Did something happen at the archive?”
Rei thought of Haruto’s seventeen-year-old correction.
Sayuri being classified as transfer.
The System prompt.
Gojo’s derived efficiency model unfolding inside him like a set of knives made from absence.
“Yes”
Akiha waited.
He did not elaborate.
She accepted that with visible effort.
“Can I help?”
The question was simple.
That made it dangerous.
Rei looked at her.
Akiha Suda. Suspicion retained. Cooperative utility stabilized. Personal rapport initiated. Social anchor potential strengthened.
The System’s words were not her.
They never would be.
He chose carefully.
“If I correct something too fast, ask me if I am sure”
She blinked.
“That is all?”
“For now”
Akiha studied him.
Then nodded.
“Are you sure?”
He almost smiled.
“No”
“Good”
He paused.
“You sound like my parents”
Her face went blank with horror.
“That is the cruelest thing you have ever said”
This time he did smile.
Only a little.
It still counted.
The second registry restoration session happened one week later.
Rei arrived prepared to be bored, baited, and observed.
He was all three.
Oda gave them water-damaged files from a different shelf this time. Not Amana-heavy. Not obviously Mikage. Contracts involving barrier maintenance, curse residue disposal, and transportation permissions between minor families and Kyoto administrative offices.
Tomonari remained polite.
Miyo remained sharp.
Akiha remained beside Rei by design or luck, and Rei no longer believed in luck inside registry archives.
The files were tedious enough to be genuine work.
That was what made the bait effective.
After an hour, Oda placed a separate folder in the center of the table.
“This one is for comparison only. No child hand touches the inner pages”
All three children looked up.
Miyo did not, because she had already been looking.
Oda opened the folder herself.
Inside was a copy of a recent security circular.
Rei saw the Gojo name before he could stop himself.
Not Satoru.
Gojo clan route adjustment.
Escort revision.
Barrier support request.
Akiha’s breath changed.
Tomonari’s posture became sharper.
Miyo watched Rei.
Of course.
The folder was not there for restoration.
It was there to see who reacted.
Rei lowered his gaze to his own file and let the Gojo name become unimportant.
It was not unimportant.
That was the work.
Oda spoke.
“This circular is included because its preservation ink matches the damaged transport permissions. You will compare paper treatment only”
Paper treatment.
Not content.
A deliciously impossible instruction for children trained to extract meaning from everything adults tried to hide.
Rei looked at the paper edges.
Not the words.
The efficiency model made the task easy.
Too easy.
The preservation ink had been applied in two layers, the second rushed. The upper right corner had been handled by someone with faint tremor in their cursed energy. Not fear. Excitement. The circular had passed through at least one office with stronger privacy charms than this archive. The route adjustment was recent enough that the residue still held urgency.
He ignored all of that.
Paper treatment only.
“Second layer is uneven” Tomonari said
Oda marked a card.
Akiha added “The lower edge dried slower”
“Good”
Rei said “The paper was stored flat before the second layer dried”
Oda looked at him.
“Why?”
He pointed to a tiny warp near the binding crease.
“Compression mark”
Correct.
Boring.
Miyo spoke.
“The content concerns the Gojo clan”
Oda looked at her.
“I said paper treatment only”
Miyo bowed.
“My apologies”
Not sincere.
Tomonari looked irritated.
Rei did not react.
Miyo continued softly “Some content changes handling urgency”
Oda’s eyes narrowed.
“Are you correcting my instruction?”
“No, Oda-san”
“Good. Then compare paper”
Miyo lowered her head.
But the statement had done its work.
The Gojo name was now alive in the room.
Rei could feel everyone not looking at it.
The efficiency model showed him the waste in their restraint. Tiny spikes of cursed energy. Attention leaking through posture. Tomonari’s pride at being near important documents. Akiha’s worry because she knew Rei cared. Miyo’s interest in who cared. Oda’s irritation. Moriyama’s distant attention from the doorway.
Rei almost laughed.
Everyone was inefficient when pretending not to see the brightest name in the world.
Including him.
The Gojo circular remained open for exactly four minutes.
Long enough.
Then Oda closed it.
“Good. Back to actual work”
The room obeyed, badly.
During the break, Miyo approached Rei.
Alone.
That was intentional.
Akiha saw and began moving.
Rei gave her the smallest shake of his head.
She stopped, unhappy.
Miyo stood beside his tray and looked down at a damaged transport file.
“Mikage-san”
Rei bowed slightly.
“Miyo-san”
“You did not look at the Gojo circular”
“I looked at the paper”
“As instructed”
“Yes”
“Are you always so obedient?”
“No”
Her eyes sharpened.
He looked up.
“That is why Moriyama-sensei trains me”
For a moment, Miyo’s expression shifted.
Amusement, perhaps.
Or recalculation.
“You are difficult to insult”
“I have been told I misunderstand them badly”
“On purpose?”
“Sometimes”
“How efficient”
The word hit too close.
Rei kept his face still.
Miyo noticed something anyway.
She leaned slightly closer.
“Do you know what people say about Satoru Gojo?”
This was a room.
Find the exit.
Not through denial.
Not through curiosity.
Through category.
“Many contradictory things” Rei said
“That he sees everything”
“People often exaggerate famous children”
“Do you think it is exaggeration?”
Rei placed a damaged file edge under a paper weight.
“I think if he saw everything, no one would bother changing his route”
Miyo paused.
Akiha, across the room, looked down quickly.
Oda snorted without looking up.
Moriyama’s presence at the doorway sharpened in what might have been approval.
Miyo’s mouth curved.
“Interesting answer”
“It is a practical answer”
“You hide behind practical answers”
“Yes”
That honesty disrupted her more than denial would have.
Rei continued sorting.
Miyo watched him another second.
Then said “My family says practical people become dangerous when forced into impossible situations”
Rei did not look up.
“Then avoid forcing them”
She laughed once.
Soft.
Not kind.
Then she returned to Tomonari.
Akiha arrived thirty seconds later.
“You told me to ask if you correct too fast”
“Yes”
“Are you sure telling Miyo to avoid forcing practical people was wise?”
Rei considered.
“No”
“Good”
“Do not enjoy this too much”
“I am being helpful”
“You are being smug”
“That too”
The restoration session ended without further obvious bait.
That meant the bait had already worked or failed invisibly.
On the way home, Haruto asked what had happened.
Rei told him.
Gojo circular.
Paper treatment.
Miyo.
Practical people.
Haruto listened without interrupting.
Then said “You answered well”
Rei waited.
Haruto looked at him.
“You are expecting correction”
“Yes”
“Good”
“There it is”
His father ignored that.
“The Gojo answer was useful. If he saw everything, no one would bother changing his route. That frames your attention as administrative rather than personal”
Rei nodded.
“The practical people answer?”
“Riskier”
“I know”
“Why say it?”
Rei looked out the car window.
Because Miyo keeps trying to turn me into a file she can read.
Because I wanted her to know I saw the pressure.
Because I am tired of being handled.
Because maybe warning someone is better than letting them think quiet means soft.
He chose the answer that could survive.
“She respects hidden edges more than soft refusals”
Haruto considered this.
“Yes”
“Was it wrong?”
“No. But it was memorable”
Rei closed his eyes.
“Which is sometimes wrong”
“Yes”
At home, Sayuri listened and frowned only once, at Miyo’s name.
“She is becoming too interested”
Rei nodded.
“What do I do?”
“Let Akiha be right in front of her”
Rei blinked.
“What?”
Sayuri poured tea.
“Miyo is watching how people react to you. If Akiha corrects you visibly, it supports your profile and gives Miyo another pattern to occupy herself with”
“That uses Akiha”
“Yes”
Rei did not like that.
Sayuri saw.
“You can ask her”
That was worse.
Asking made it honest.
Honesty made it heavier.
Haruto picked up his tea.
“If she agrees, it becomes cooperation. If you arrange it without her knowledge, it becomes use”
Rei looked between them.
“Adults do this all the time”
“Yes” Sayuri said “And look how well the world turned out”
He had no answer.
That night, Rei opened the System.
[Cursed Energy Efficiency integration stabilized]
Visible output reduction improved
Passive leakage reduced
Masking Protocol recalibration available
Masking Protocol: 84%
He selected recalibration.
Not impulsively.
Not from desire.
From purpose.
[Masking Protocol recalibration initiated]
Base external profile retained:
- support-inclined
- moderate reserves
- excellent control through training
- field recorder habits
- barrier curiosity explainable through maternal influence
Efficiency layer added:
- reduced passive cursed energy leakage
- smoother apparent output during low-level tasks
- visible imperfections preserved for plausibility
- high-output concealment unchanged
Masking Protocol recalibrated]
Current Masking Protocol: 87%
Visible imperfections preserved.
Rei stared at that line.
The System had learned to keep mistakes.
Or he had taught it to.
He did not know whether to be proud.
Another message appeared.
[Social Anchor recommendation]
Akiha Suda may assist in maintaining plausible peer correction pattern.
Warning:
Using social anchor without informed consent may reduce trust stability.
Rei closed the interface.
The System was becoming annoyingly moral in the exact places where morality was inconvenient.
The next day, during preliminary instruction, Rei asked Akiha to walk with him to the storage alcove.
She looked suspicious immediately.
Good instincts.
“What is it?” she asked
He glanced toward the main hall.
Moriyama was busy explaining to Daigo that inherited arrogance did not count as reinforcement. Tomonari was not present. Miyo was not present. Oda was not there. No registry observer stood by the door.
As private as the compound allowed.
“I need to ask something unfair”
Akiha became very still.
“Then why ask?”
“Because not asking would be worse”
She considered that.
“Ask”
Rei took a breath.
“Miyo is watching how people react to me. If you correct me openly when I answer too fast or look too certain, it makes my profile more believable”
Akiha said nothing.
Rei forced himself not to fill the silence.
Sayuri’s questions returned.
If you trust Akiha because she warned you, what have you already given her?
If you distrust everyone, who benefits from your isolation?
Akiha looked toward the hall.
“You want me to help you seem less strange”
“Yes”
“By making myself part of your strange”
He winced.
“Yes”
“Why me?”
Because you noticed first.
Because you kept quiet.
Because the System says social anchor and I hate that it is right.
Because I trust you more than is safe.
Because you are already involved and pretending otherwise insults both of us.
He said “Because you already correct me when I am wrong”
Akiha looked unimpressed.
“That is not the whole answer”
“No”
“Can you give the whole answer?”
“No”
She looked at him for a long time.
Then nodded once.
“Good”
He blinked.
“You are all terrible”
“Probably”
Akiha folded her hands.
“I will help”
Rei’s chest tightened.
“You should think first”
“I did”
“That was fast”
“I think quickly when adults are being stupid through children”
The sentence sounded too much like something her mother would say.
Rei bowed his head.
“Thank you”
“I have conditions”
Of course she did.
He looked up.
“What conditions?”
“One. You tell me when the correction is for show and when it is real”
“That defeats some purpose”
“I did not say immediately. But eventually”
Rei thought about it.
“Agreed”
“Two. If I ask whether something is dangerous, you do not say I do not know unless you truly do not know”
Hard.
Fair.
“Agreed”
“Three. If I become part of your explanation, you do not decide alone what that means for me”
That one landed deepest.
Rei lowered his gaze.
“Agreed”
Akiha watched him.
“Good”
“You sound like everyone else”
“I know”
They returned to the hall.
Moriyama looked at them once.
Rei was almost certain she had heard enough to know the shape and not enough to intervene.
Which probably meant enough.
During the next drill, Rei answered one residue classification too precisely.
Akiha immediately said “Are you sure?”
The room shifted.
Not much.
Enough.
Rei frowned at the talisman.
“No. It may be mixed handling”
Moriyama looked at Akiha.
Then at Rei.
Then marked the board.
Miyo was not present to see it.
That was fine.
Patterns needed practice before performance.
Daigo muttered “Now Suda is correcting him too”
Akiha looked at him.
“Someone should”
Daigo opened his mouth.
Moriyama said “Zenin, invite correction less often if you dislike seeing it”
He closed it.
Rei carefully did not smile.
Akiha corrected him twice more that day.
Once for show.
Once because he was actually wrong.
That distinction mattered.
It bothered him that he was relieved by it.
That night, the System updated.
[Social Anchor condition strengthened]
Akiha Suda:
- informed cooperation established
- correction pattern initiated
- trust stability improved
- mutual risk acknowledged
Public Self Construct strengthened
Masking Protocol: 88%
Rei read the update.
Then, after a moment, opened his notebook.
He wrote:
Akiha agreed to help correct my certainty.
Conditions:
1. Tell her eventually when corrections are for show or real.
2. Do not use I do not know unless true.
3. Do not decide alone what being part of my explanation means for her.
Important: consent makes the pattern heavier but cleaner.
He paused.
Then added:
Efficiency is not only using less cursed energy. It is wasting fewer people.
That line embarrassed him more than the last one.
He kept it too.
Three weeks later, the old plum tree bloomed.
Not fully.
Only one branch.
Small pale blossoms opened against the dark wood, fragile and almost colorless in the morning light.
Sayuri stood beneath it for a long time.
Haruto joined her.
Rei watched from the veranda and did not interrupt.
The eastern boundary remained quiet.
The registry request cycle slowed.
Miyo did not return for the next restoration session.
Tomonari did, but without her, he was easier to keep within politeness. Akiha corrected Rei twice in front of him. Oda called both of them tolerable pests. Moriyama continued hostile questioning. Daigo continued being Daigo.
For a while, life settled into a shape almost stable enough to distrust less.
Then the Gojo rumor became a notice.
It arrived through Moriyama at the end of class on a clear afternoon.
She read the message once.
Then again.
Her expression did not change, which meant every adult in the room should have been concerned.
The children watched her.
Even Daigo had enough instinct to shut up.
Moriyama folded the note.
“Next month, this compound will host a joint preliminary demonstration for selected Kyoto and Tokyo-affiliated children”
Akiha’s posture changed.
Tomonari, present that day, looked alert.
Rei felt the room’s boundaries sharpen around him.
Moriyama continued.
“Participation is not optional for those selected. Most of you are not selected”
Daigo looked offended preemptively.
Moriyama’s gaze moved to him.
“Zenin Daigo”
He straightened.
“Suda Akiha”
Akiha lowered her head.
“Kamo Tomonari”
Tomonari nodded.
“Mikage Rei”
Rei’s heartbeat slowed.
Not calm.
Concentration.
Moriyama’s eyes stayed on him for half a second longer than the others.
Then she said “The Gojo heir will attend”
The room changed.
No one spoke.
The strongest child in the world had entered without entering.
Satoru Gojo.
True Six Eyes.
Direct scrutiny critical risk.
Rei felt the Masking Protocol fold tighter around him, smoother now after recalibration, efficient enough not to ripple the room. Yuta’s reserve sank deep. Gojo’s derived efficiency model narrowed itself as if ashamed of its source. Tengen’s barrier perception lowered. Kusakabe’s control became breath. Nanami’s reinforcement became stillness. Yuji’s body kept his hands from shaking.
Akiha looked at him.
Not obviously.
Enough.
Are you sure?
The question did not need words.
Rei looked down at the talisman in front of him.
No.
He was not sure.
Not even close.
Moriyama dismissed the class.
No one moved at first.
Then everyone moved at once.
Daigo began talking too loudly about finally seeing whether the rumors were exaggerated. Tomonari was silent in a way that meant he was already preparing reports in his head. Akiha packed slowly, staying near Rei without making it obvious. Moriyama did not approach him. That was intentional. Public concern would be worse than none.
When Haruto arrived, he already knew.
Of course.
His face was calm enough that Rei hated it.
On the ride home, neither spoke for ten minutes.
Then Haruto said “We expected this eventually”
Rei looked out the window.
“Eventually is next month”
“Yes”
“The System said direct Six Eyes scrutiny is a critical risk”
He did not realize he had said the first two words until the car went utterly silent.
Haruto did not move.
Rei stopped breathing.
There it was.
Not the full truth.
Not even close.
But a word with no safe explanation.
System.
The driver continued forward, separated by the privacy charm Haruto had placed before they left. Thank every god and curse that privacy charms existed.
Haruto looked at Rei.
His voice was very quiet.
“Do not explain in the car”
Rei’s hands curled in his lap.
“Yes”
The rest of the ride passed in silence.
But it was not the old silence.
Something had crossed a threshold.
At home, Sayuri was waiting in the family room.
Haruto closed the door.
Rei stood before both of them and felt, for one dizzy moment, that every mask he had built was paper held over fire.
Sayuri looked at Haruto.
He said only one word.
“System”
Her gaze moved to Rei.
The room became still.
Rei closed his eyes.
The ocean waited.
The mask held.
The door stood open now, whether he liked it or not.
When he opened his eyes, both his parents were watching him.
Not as a file.
Not as an anomaly.
Not yet as something understood.
As their son, standing at the edge of a truth too large for the room.
Rei swallowed.
“I can explain some of it” he said
Sayuri’s face was pale.
Haruto’s expression was unreadable.
“Not all?” she asked
“Not safely”
The old answer.
Still true.
But smaller now.
Haruto sat.
Sayuri sat beside him.
Neither looked away.
“Then start with what will help us keep you alive next month” Haruto said
Outside, the old plum tree’s first blossoms trembled in the wind.
In Tokyo, Satoru Gojo was preparing to become visible to children who had already spent their lives hearing what he meant.
In Kyoto, Rei Mikage finally understood that hiding behind the strongest would not work once the strongest was close enough to look back.
