The first time Rei Mikage entered a room full of jujutsu children, he understood why adults were so fond of ruining them.
It was not because children were easy to break.
That would have been too simple.
Children broke loudly. They cried, sulked, screamed, clung, rebelled, ran, froze, lied badly, trusted worse, and carried fear on their faces like wet ink. Breaking them required cleanup, excuses, replacements, and the sort of paperwork minor administrators resented because it gave important families opportunities to ask why their investments had been damaged.
No.
Adults ruined children because children could still be shaped.
That was worse.
The training hall belonged to a Kyoto-affiliated registry compound, not the actual school. Rei knew the difference before anyone explained it. The compound was a place for preliminary instruction, classification, early screening, and the quiet sorting of useful assets from inconvenient ones. The real Kyoto Jujutsu High waited later, for those old enough, strong enough, connected enough, or unlucky enough to be sent into proper sorcerer training.
This place was smaller.
Cleaner.
Crueler in a way that wore softer shoes.
The outer gate stood beneath a winter-gray sky, its wooden beams old enough to have absorbed generations of fear. Paper seals lined the lintel in neat rows. None of them were decorative. Rei could feel the layered barrier as he passed through it with Haruto at his side, the pressure sliding over his skin like cold water testing for cracks. His father did not slow down. Neither did Rei.
That was the first test.
He knew because the boy walking ahead of him flinched.
The boy’s mother placed a hand on his shoulder too quickly, trying to make it look like reassurance rather than correction. Too late. A woman near the registry desk saw it. A clerk saw it. The instructor pretending not to watch from the inner veranda saw it.
Rei saw everyone seeing it.
He lowered his gaze and adjusted the strap of his small charm pouch.
Useful children noticed.
Safe children did not look like they noticed.
Haruto’s sleeve brushed Rei’s shoulder once.
A warning.
Or praise.
With his father, those often felt the same.
The preliminary hall held nine children that morning.
Four boys. Five girls. Ages six to eight. All from minor families, branch houses, administrative bloodlines, or households attached to more important names by old obligations. No heir of the three great clans would be tested here unless someone was making a political point. Still, the great clans were present in the way mountains were present in valleys: unseen, cold, and shaping everything.
A boy with severe eyes introduced himself as Daigo Zenin before anyone asked.
Not main family, Rei decided immediately.
Main family children did not need to place the name so sharply on the table. Branch family, then. Close enough to weaponize the name, far enough to bleed for it.
A girl with a pale ribbon and careful posture belonged to a Kamo retainer household. Her name was Akiha Suda. She carried herself like someone who had been told not to embarrass her family so often that embarrassment had become part of her spine.
Two siblings came from the Inoue family, barrier assistants with poor technique inheritance but excellent record-keeping. The younger one kept staring at the ceiling seals as if afraid they might fall. The older one pretended not to be afraid on his behalf.
There was a girl named Tomoe whose cursed energy smelled faintly of wet iron, a thin boy called Renzo who could barely keep his hands still, and another boy who had already decided Rei was not important because the Mikage name had not impressed him.
That boy’s name vanished from Rei’s mind almost immediately.
He allowed it.
Some people were safer as background.
The instructor entered after the children had been seated for exactly seven minutes.
That, too, was deliberate.
Enough time for nervous children to reveal themselves.
Enough time for proud children to establish hierarchy.
Enough time for quiet children to decide whether silence was a shield or an invitation.
She was a woman in her early forties with graying hair tied at the nape of her neck and a scar along one side of her mouth that made every neutral expression look faintly displeased. Her name was Moriyama Keiko. Semi-Grade 1, according to Haruto. Strong enough to matter here. Not strong enough to escape assignments like this one.
Rei liked her immediately.
Not because she seemed kind.
Because she did not.
Kind adults in jujutsu spaces were either dangerous, tired, or lying to children for reasons that might become dangerous later. Moriyama looked at them like tools she had not yet inspected and said nothing for a full ten seconds.
Several children shifted.
Rei counted their breaths.
Moriyama’s gaze passed over him once and did not return.
Good.
“Preliminary instruction is not school” she said
Her voice was dry, flat, and practical.
“You are not here to make friends. You are not here to prove your family’s worth. You are not here to impress me. You are here because someone has decided you may one day be useful enough to risk training”
The word struck the room differently than it struck Rei.
Some children straightened.
Some paled.
Daigo Zenin looked offended.
Moriyama noticed and ignored him, which was the correct response.
“If you are strong, you will learn restraint. If you are weak, you will learn application. If you are frightened, you will learn how to function while frightened. If you are stupid, you will hopefully learn silence before your stupidity kills someone near you”
No one moved.
Rei thought, not for the first time, that jujutsu adults wasted no effort pretending childhood was sacred.
Moriyama stepped to the side.
Behind her, an assistant unrolled a hanging paper chart with six categories written in bold black strokes.
Perception.
Control.
Reinforcement.
Technique manifestation.
Barrier sense.
Composure.
Not strength.
Not talent.
Not potential.
Rei understood the shape of the day before she explained it.
They were not measuring who could win.
They were measuring who could be sent where, taught what, used how, and watched by whom.
Moriyama tapped the chart once.
“Today we observe. You do not pass. You do not fail. You are recorded”
That was a lie.
A true one, in Haruto’s sense.
Recording was passing and failing in slower language.
The first exercise was perception.
Each child was placed before a lacquered tray containing three covered objects. One object carried cursed residue. One carried ordinary human handling. One carried nothing but a masking charm meant to imitate residue poorly enough that trained children should eventually learn the difference.
Eventually.
Most of them were seven.
The first boy guessed wrong twice and looked like he might cry. Moriyama marked the board without comment. Akiha Suda identified the residue correctly but mistook the masking charm for a weak curse trace. Daigo Zenin announced both correct answers and then smirked before Moriyama informed him that his first answer had been late enough to count as hesitation.
The smirk died beautifully.
When Rei’s turn came, he sat in front of the tray and placed both hands on his knees.
Three covered objects.
Left: ordinary handling. A clerk had touched it, then Moriyama, then the assistant. Ink on one finger. Slight irritation from a paper cut. No cursed residue worth noting.
Center: actual residue. Low-grade curse, old, probably collected from a school corridor. Fear of exams, embarrassment, resentment toward a teacher. Sour and thin.
Right: masking charm. Too regular. Too intentional. Cursed energy arranged to resemble residue by someone who understood structure but not rot.
Rei looked at the tray.
If he answered instantly, Moriyama would mark him as highly sensitive.
If he answered too slowly, Haruto’s report would look suspicious.
He counted two breaths.
Then a third.
He touched the center cloth and frowned.
“This one”
Moriyama watched him.
“Why?”
Rei tilted his head, letting his expression become uncertain.
“It feels dirty”
A few children laughed.
Moriyama did not.
“Dirty how?”
Rei hesitated.
This was where children gave too much.
He remembered Haruto’s second rule.
“I do not know the words”
Moriyama marked the board.
Not excellent.
Not poor.
Likely promising.
Acceptable.
“Next”
Rei returned to his place.
Haruto was not present in the hall. Parents had been dismissed to a waiting room after registration. That was another test. Children behaved differently without family beside them.
Rei sat with his back straight and his hands folded.
Daigo Zenin leaned slightly toward him.
“Mikage, right?”
Rei looked at him.
“Yes”
“Your family does cleanup”
“Yes”
Daigo’s mouth curled.
“My uncle says support families are useful because someone has to follow real sorcerers around”
Akiha Suda looked down quickly.
Renzo stared at his own hands.
The unnamed boy snickered.
Rei considered several answers.
Most of them belonged to someone older, sharper, and less committed to staying alive.
So he chose the mask.
“My father says real sorcerers leave messes because they are busy”
Daigo blinked.
That was not the reaction he had expected.
Rei looked back toward Moriyama.
“It is good that everyone has work”
The sentence landed with perfect childish sincerity.
Akiha covered her mouth.
The unnamed boy frowned, trying to decide whether Rei had insulted Daigo or agreed with him.
Daigo decided on insult.
His cursed energy twitched.
Small.
Undisciplined.
Angry.
Moriyama’s voice cut across the room.
“Zenin”
Daigo straightened.
“Yes, Moriyama-sensei”
“If you cannot sit beside a support family without leaking cursed energy, I will record that”
Daigo went red.
Rei kept his face blank.
Useful children did not smile at small victories.
They stored them.
The second exercise was control.
A line of thin candles had been arranged along a stone table, each flame protected by a simple charm. The task was not to extinguish them. That would have been easy for some and impossible for others. The task was to feed a thread of cursed energy through the charm without disturbing the flame.
Control, not power.
The first three children failed.
One snuffed the candle. One cracked the charm. One panicked and withdrew before his cursed energy reached the wick.
Akiha did well. Her thread trembled, but the flame leaned only slightly.
Daigo used too much force and made the flame flare blue. He looked proud until Moriyama marked the board without praise.
A case of theft: this story is not rightfully on Amazon; if you spot it, report the violation.
Then Rei stepped up.
The candle flame was small and yellow.
Kusakabe’s template settled into his breathing before he consciously called on it. That was dangerous. The longer a template stayed equipped, the more natural it became. Not possession. Not instinct stolen from another person. Something quieter. A path worn into the soul by use.
Rei could thread cursed energy through the charm cleanly.
Too cleanly.
He needed a child’s result.
Not a poor one.
A believable one.
He sent cursed energy forward.
Thin.
A little uneven.
He let it wobble near the charm edge, corrected too late, then stabilized it enough that the flame quivered but did not go out.
Moriyama’s eyes sharpened.
Rei pretended not to notice.
The flame held for five seconds.
Six.
Seven.
He withdrew.
The candle remained lit.
“Good correction” Moriyama said
Not good control.
Good correction.
That mattered.
A child with perfect control was suspicious.
A child who made a small mistake and fixed it was teachable.
Rei bowed.
“Thank you”
As he returned to his place, Daigo muttered “Cleanup boy has steady hands”
This time, Rei did not answer.
Silence could be a blade if left in the wound long enough.
The third exercise was reinforcement.
Rei disliked it immediately.
Perception could be moderated through language. Control could be disguised through small errors. Reinforcement was harder because the body had habits, and Yuji’s template had been teaching his body to survive better than it should.
The instructor placed a padded striking post in the center of the room.
“Strike once” Moriyama said “Then receive one strike from the post”
The post was not ordinary wood. It was mounted on a simple cursed mechanism that returned force proportional to the impact delivered. Hit lightly, receive lightly. Hit hard, receive hard. Reinforce poorly, bruise. Reinforce well, learn.
Daigo brightened.
Of course he did.
He struck first among the children, because Moriyama allowed pride to volunteer for pain whenever possible. His punch was strong for his age, reinforced along the knuckles and wrist, poorly supported through the shoulder. The post absorbed the blow, then snapped forward.
Daigo took the return strike against his forearm.
He slid back two steps but remained upright.
Not bad.
Moriyama marked the board.
“Too much wrist. Again later”
Daigo looked pleased anyway.
Akiha struck carefully and received carefully. Her reinforcement was thin but even. The Inoue younger sibling cried after his return strike and had to be escorted aside by his brother, who then performed worse because anger had disrupted his flow.
Rei watched all of it.
By the time his name was called, he knew exactly how much force would look right.
That should have helped.
Instead, it made everything harder.
He walked to the post.
Placed his feet.
Not too perfect.
Raised his small fist.
Not too high.
Cursed energy gathered along his hand and forearm. Kusakabe’s control shaped it. Yuji’s body aligned behind it. His shoulder settled. His hips prepared to rotate.
Too good.
He loosened his stance.
The punch landed with a dull thud.
Respectable for a six-year-old.
Not remarkable.
The post absorbed the force.
Then returned it.
Rei saw the mechanism release. Felt the cursed energy pulse. Calculated the angle. His body wanted to shift, soften, redirect, root. It wanted to take the strike properly.
He had to let it hit him wrong enough.
That went against every instinct he had spent a year sharpening.
The padded arm slammed into his forearm.
Pain bloomed.
He stumbled back one step.
Only one.
He almost made it two.
Too late.
Moriyama’s gaze fixed on his feet.
Rei hissed and grabbed his arm.
A real reaction. The pain was real, at least. He let his eyes water because they wanted to.
Moriyama approached.
“Show me”
Rei extended his arm.
She pressed two fingers against the bruise.
He flinched.
“Reinforcement present. Incomplete distribution. Good recovery”
She looked at his feet again.
“Your fall training is better than your striking”
Rei lowered his head.
“Father teaches me to fall”
“Good. Most sorcerers learn too late”
She turned away.
Rei returned to his seat with his heart beating too fast.
Not because of pain.
Because Moriyama had seen the important part.
Not strength.
Recovery.
People looked for what children could do.
Good instructors looked for what children survived.
By midday, the class had been divided into categories that would not be spoken aloud but were obvious to anyone paying attention.
Daigo Zenin: aggressive, decent reinforcement, poor control under provocation, politically sensitive.
Akiha Suda: disciplined perception, moderate control, low confidence, useful for records or support.
Inoue elder sibling: protective impulse, unstable under family stress.
Inoue younger sibling: too frightened, monitor.
Renzo: twitchy cursed energy, possible technique manifestation if not crushed by anxiety.
Tomoe: unusual energy scent, require follow-up.
Rei Mikage: support-inclined, good correction, good fall training, early Residual Threading expression, not visibly ambitious.
That was the mask.
Not perfect.
But alive.
The afternoon exercise changed everything.
Moriyama brought them to a lower chamber beneath the compound.
The parents were still not present.
The assistants were.
Three of them stood near the walls with talismans ready. That alone told Rei the exercise carried controlled danger. Not enough to kill children unless something went very wrong, but enough to teach them that fear in jujutsu was not theoretical.
The chamber was rectangular, windowless, and lined with layered seals. A small paper-screen enclosure sat in the center, no larger than a storage cabinet. Cursed energy pressed weakly from inside it.
Several children stiffened.
Daigo smiled.
Rei did not.
He remembered the storehouse curse.
Moriyama stood beside the enclosure.
“Inside is a fourth-grade curse restrained by a three-layer seal. You will not fight it. You will observe, maintain distance, and identify residue direction after it moves. If you panic, step back. If you interfere without instruction, you will be removed from the chamber and your report will reflect poor judgment”
A hand rose.
It belonged to Akiha.
“What if the seal fails?”
Moriyama looked at her.
“Then you learn why we have assistants”
Akiha lowered her hand.
Not reassured.
Intelligent girl.
The enclosure opened.
The curse inside was smaller than the storehouse thing, but faster. It looked like a knot of gray cloth soaked in saliva, with two bent legs and a mouth hidden where its stomach should be. The seals pinned it inside a square marked on the floor.
It twitched.
Several children recoiled.
Rei kept his breathing even.
The curse moved around the square, bumping against invisible pressure when it neared the edge. Each collision left a smear of residue in the air, faint and ugly.
Moriyama called the children one by one to identify direction, density, and emotional origin.
Most got direction.
Few got density.
No one was expected to get origin.
When Rei’s turn came, he saw it immediately.
Not only the direction.
The curse had been formed from fear of being locked in a dark place.
A child’s fear.
Old, repeated, probably from some storage room or disciplinary space where adults had mistaken cruelty for correction. The residue clung low to the floor, crawling back toward corners. Its movements were not random. They were searching for exit lines.
Rei’s stomach turned.
“Direction?” Moriyama asked
“Northwest”
“Density?”
“Weak but concentrated at floor level”
Moriyama’s mouth barely moved.
Good.
“Origin?”
This was not part of the expected question.
Rei felt the room’s attention shift.
Daigo looked irritated. Akiha looked curious. The assistants looked bored, which meant they were listening closely.
Rei had to choose.
“I do not know” he said
Moriyama stared at him.
He added “It feels like a closed room”
Akiha inhaled softly.
Moriyama marked the board.
“Acceptable”
The curse struck the barrier again.
This time, one of the seals flickered.
Rei saw the error before the adults did.
Not because he was better than them.
Because he was smaller, closer to the floor, and already watching the residue lines rather than the curse itself.
A thin thread had slipped beneath the square, drawn toward a crack in the chamber stone where old fear had gathered. The barrier was still intact, but the curse was not trying to break the whole thing. It was pressing through the weakest seam, smearing itself along a path too low and too pathetic for prideful eyes.
The assistant on the left noticed half a second later.
Half a second was enough.
The curse flattened suddenly.
Its body poured through the edge of the seal like wet cloth forced beneath a door.
One child screamed.
Moriyama moved.
The assistants moved.
Daigo moved too, because pride was faster than instruction.
He stepped forward, cursed energy flaring around his fist.
Wrong.
The curse was not attacking the nearest target. It was fleeing toward the corner where the Inoue younger sibling had stumbled back and frozen. The child’s fear was fresh, bright, compatible. The curse changed direction mid-skitter.
Rei’s body moved before his mask could vote.
He did not sprint.
That would be too obvious.
He dropped.
Smallness became useful.
His hand slapped the floor where the residue thread crossed an old seal line. Residual Threading caught. Kusakabe’s control narrowed his cursed energy into something thin enough to pass as family technique. Yuji’s body gave him the balance to twist without falling flat.
He pulled.
The thread snapped taut.
The curse jerked sideways.
Not stopped.
Delayed.
“Move” Rei shouted
The Inoue older brother grabbed the younger and dragged him back just as the curse scraped across the floor where his ankle had been.
Daigo’s fist came down late and hit stone.
Moriyama’s talisman struck the curse a heartbeat after that.
The chamber flashed.
The curse dissolved into smoke and a stain.
Silence followed.
Real silence.
The kind that came after everyone understood the difference between controlled danger and danger that had briefly stopped obeying.
Rei was still crouched with one hand against the floor.
His palm burned.
Not from injury.
From residue.
He withdrew slowly.
Moriyama turned toward the assistants first.
“Report the seal flaw”
One assistant bowed too deeply.
“Yes, Moriyama-sensei”
Then she looked at Daigo.
“You moved without instruction”
Daigo’s face went pale with anger.
“I was going to exorcise it”
“You were going to hit the floor while it attacked someone behind you”
His mouth snapped shut.
Moriyama’s gaze shifted to Rei.
The room seemed to shrink.
“And you”
Rei lowered his head.
“I am sorry”
“For what?”
“I interfered without instruction”
“Yes”
Her voice was unreadable.
“Why?”
The correct answer was not because your seal failed
The correct answer was not because Daigo is an idiot
The correct answer was not because I saw the thread and knew I could pull it
He chose the safest truth.
“The residue line reached him”
Moriyama watched him.
“You saw that?”
Rei nodded once.
“It was low”
“Low?”
“Near the floor”
Moriyama looked toward the stain.
Then toward the crack in the chamber stone.
Then back at Rei.
“Show me”
The words were quiet.
Too quiet.
Rei’s pulse kicked.
This was dangerous.
The event had already happened. The residue was still there. If he failed to show enough, she would know he was lying. If he showed too much, she would know he was hiding.
He walked to the edge of the square.
Crouched.
Pointed to the crack.
“Here”
Moriyama crouched beside him.
For a woman who had looked severe standing up, she became almost frightening at eye level.
“Continue”
Rei touched the floor two inches away from the crack.
“Then there. It went under the seal. Like water”
“Not through?”
“No. Under”
One assistant cursed very softly.
Moriyama heard it.
Everyone heard it.
She stood.
“Exercise complete”
No one argued.
As they left the chamber, Akiha Suda walked beside Rei without looking at him.
After several steps, she whispered “You saved him”
Rei kept his eyes forward.
“Moriyama-sensei saved him”
“You pulled it first”
“I saw a line”
Akiha looked at him then.
Her expression was careful.
Not suspicious exactly.
Worse.
Grateful.
Rei did not know what to do with that.
Daigo pushed past them hard enough that his shoulder struck Rei’s.
Yuji’s template corrected his balance instantly.
Rei forced himself to stumble.
Daigo noticed the stumble.
Good.
Akiha noticed the correction before the stumble.
Bad.
Very bad.
She said nothing.
That was either kindness or intelligence.
Rei hoped, for both their sakes, that it was fear.
Parents were allowed back into the compound at sunset.
By then, the children had been fed, the reports updated, the chamber sealed off, and the official version shaped into something administrative enough to survive.
Minor seal flaw during controlled observation.
Instructor neutralized curse.
No serious injuries.
One child support response noted.
Daigo Zenin had a bruise on his pride and two scraped knuckles. The Inoue younger sibling had stopped crying but had not released his brother’s sleeve. Akiha Suda kept glancing at Rei and then looking away. Moriyama spoke to each parent briefly.
When Haruto entered, Rei knew from his face that he had already heard enough to be worried.
Not frightened.
Worried was more controlled.
More Mikage.
Moriyama approached them with Rei’s report tablet in hand.
“Mikage”
Haruto bowed.
“Moriyama-sensei”
“Your son has good eyes”
“Residual Threading appears to be developing early”
“That is one way to write it”
Haruto did not blink.
Rei stood between them and wished he were anywhere else.
Moriyama looked down at him.
“You saw the flaw before my assistant did”
Rei lowered his head.
“I saw the thread near the floor”
“Yes. You have said that several times”
That was not praise.
Haruto’s voice remained mild.
“Was his conduct inappropriate?”
“He interfered without instruction”
Haruto’s hand tightened slightly at his side.
Moriyama continued.
“And prevented another child from being injured because my containment seal had a maintenance flaw”
Haruto said nothing.
Smart.
Moriyama handed him the report tablet.
“I will record him as support-inclined with strong residue sensitivity, good composure under pressure, and a tendency to act when he sees a line of intervention”
Haruto read the tablet.
“That last phrase is unusual”
“So is he”
Rei’s stomach sank.
Moriyama’s scar pulled slightly as her mouth shifted into something too flat to be a smile.
“Do not panic, Mikage. Unusual is not the same as important”
Haruto bowed again.
“We understand”
Moriyama looked at Rei one last time.
“No, you do not”
For a second, Rei thought she was speaking to his father.
Then her eyes settled fully on him.
“You are young, so I will say this plainly. Seeing a way to help does not mean you understand the cost of helping. Learn the difference before someone uses it against you”
Rei stared at her.
The warning slid beneath his skin and stayed there.
“Yes, Moriyama-sensei”
She turned away.
The conversation was over.
On the ride home, Haruto did not speak for almost half an hour.
The car belonged to the registry, driven by a non-sorcerer assistant who either knew nothing or had been paid enough to know nothing professionally. Snow began falling again as Kyoto slid past the window in dim golds and grays.
Rei sat with his charm pouch in his lap.
Haruto’s report tablet rested on his knee.
Finally, his father said “You acted”
Rei looked down.
“Yes”
“Why?”
The question was not Moriyama’s.
It was sharper because Haruto was not asking for the report version.
Rei could have lied.
He almost did.
Then he remembered Haruto beside his bed, saying secrecy would become too heavy for a child’s hands.
Not everything.
A little.
Enough.
“He was going to be hurt”
Haruto waited.
“And I could stop it”
The car hummed.
Snow touched the window and vanished.
Haruto looked at him for a long time.
“That is a dangerous reason”
Rei’s hands tightened around the pouch.
“I know”
“No. You do not”
There was no anger in it.
Only certainty.
Haruto looked out the window.
“Every sorcerer who dies young believes the same thing at least once. Someone will be hurt. I can stop it. Therefore I must”
Rei said nothing.
“In the moment, it feels noble. Later, if you survive, you realize the world can create more pain than your body can stand between”
The words should have sounded cynical.
They sounded tired.
Rei thought of Shibuya.
Of civilians crushed into stations.
Of transfigured humans.
Of Nanami walking burned through a nightmare.
Of Nobara’s face.
Of Yuji breaking under the weight of being alive.
He whispered “Then what should I do?”
Haruto turned back to him.
“Learn how much you can carry before you reach for more”
Rei looked at the report tablet.
“Moriyama-sensei said I do not understand the cost”
“She is right”
“I still saved him”
“Yes”
Haruto’s voice softened by a fraction.
“And that is why the lesson will be difficult”
The car continued through Kyoto.
Neither spoke again.
At home, Sayuri read the report twice.
Then she read what Haruto had not said.
Rei stood in the family room while his mother sat near the brazier, the tablet balanced on her lap. Her face gave nothing away. That was how Rei knew she was upset.
Finally, she placed the tablet down.
“You used your technique in front of other children”
Rei nodded.
“To stop a curse that should not have escaped”
He nodded again.
“Did anyone see more than they should?”
Rei thought of Akiha.
Her careful eyes.
The way she had noticed his correction before his stumble.
“I do not know”
Sayuri closed her eyes.
That answer hurt her more than a lie would have.
When she opened them, she looked at Haruto.
“The Suda girl?”
Haruto’s brows lifted slightly.
Rei stared.
Sayuri looked back at him.
“Children from retainer households are trained to watch reactions. Girls especially. People underestimate them because they are polite”
Rei swallowed.
“She saw something”
“What?”
“I do not know. Maybe that I moved better than I pretended”
Sayuri breathed out slowly.
Haruto rubbed a hand over his face.
For the first time, Rei saw both his parents look their age.
Not old.
Just mortal.
Responsible for a child shaped like a secret in a world that punished improper secrets.
“I am sorry” Rei said
Sayuri’s gaze softened immediately.
That made it worse.
“Come here”
He went.
She pulled him into her arms carefully, as if he were still bruised. He was not, mostly. Yuji’s template had helped with that. Another thing to hide.
“You saved a child” she said against his hair “Do not apologize for that part”
Rei closed his eyes.
“What part should I apologize for?”
Haruto answered.
“Surviving sloppily”
Rei almost laughed.
Sayuri gave Haruto a look over Rei’s head.
He shrugged faintly.
“It is accurate”
It was.
So Rei nodded into his mother’s sleeve.
“I will do better”
Sayuri held him tighter.
“That is not always what mothers want to hear”
Rei did not know what to say to that.
There were many things his old life had not prepared him for.
Being loved by people he was lying to was one of them.
That night, Rei opened the System later than usual.
He expected nothing.
The day had been dangerous, but not the way the storehouse had been. He had not nearly died. He had not defeated a curse. He had not unlocked some dramatic new power through blood and screaming.
He had only made a choice in front of witnesses.
Apparently, that was enough.

Not Yuji’s natural brawler reinforcement. Not Todo’s monstrous pressure. Not Sukuna’s absurd durability. Not Gojo’s refined perfection.
Nanami Kento.
Stable.
Professional.
Reliable.
A man who did not waste motion.
A man who understood labor, limits, duty, exhaustion, and the tragedy of showing up anyway.
For a long moment, Rei did not equip it.
He remembered Nanami’s final walk.
Half-burned.
Still moving.
Still killing curses.
Still thinking of others.
Malaysia.
The word hurt in a way he had not expected.
Not because he knew Nanami personally.
He did not.
Not yet.
Maybe he never would, if he changed enough.
But the template in front of him was not a collectible.
It was a life reduced to function by a System that did not grieve.
Rei sat in the dark and felt, suddenly, very young.
Then he equipped it.
[Cursed Energy Reinforcement equipped]
[Nanami Kento — Stable Professional Reinforcement]
Active Loadout updated:
Cursed Energy Foundation:
- Cursed Energy Control — Kusakabe Atsuya
Body / Physical Template:
- Yuji Itadori — Future-Imprint
Cursed Energy Reinforcement:
- Nanami Kento — Stable Professional Reinforcement
The effect was quiet.
No pain this time.
No seizure of muscle and bone.
Instead, Rei felt a weight settle over his cursed energy like a properly tailored coat.
Not stronger in the childish sense.
Better arranged.
His reinforcement no longer tried to gather where fear sent it first. It distributed in clean planes: forearm, shoulder, ribs, thigh, jaw. Practical coverage. No waste on intimidation. No dramatic flare.
He lifted one hand.
Cursed energy coated it.
Thin.
Steady.
Boring.
Perfect.
Rei almost smiled.
Then the System produced one final message.
[Warning]
Current active template synergy increases survivability beyond registered profile.
Unmasked physical response may contradict public identity.
Recommendation:
Fail believably.
Rei read that twice.
Then, despite himself, he laughed.
Once.
Quietly.
A child’s sound in a dark room.
A tired sound.
A dangerous one.
The next morning, Haruto swept Rei’s leg during training.
Rei let himself fall.
Not too well.
Not too badly.
His shoulder struck the ground with enough force to bruise, but Nanami’s reinforcement spread the impact before pain could bloom fully. Yuji’s body wanted to roll. Kusakabe’s control wanted to correct. Rei held both back by a hair’s breadth and landed like a disciplined, support-inclined child with good training and limits everyone could understand.
Haruto looked down at him.
For a long moment, he said nothing.
Then he extended a hand.
Rei took it.
His father pulled him up.
“You are learning”
Rei dusted off his sleeve.
“Yes”
Haruto’s eyes searched his face.
“To fall?”
Rei thought of the System’s warning.
Fail believably.
He looked at the practice yard, at the cold morning, at the estate walls that kept out far less than his parents hoped.
Then he looked back at his father.
“To be useful”
Haruto’s expression shifted.
Pride.
Fear.
Something between them.
“Again” he said
Rei raised his hands.
The world kept looking toward Gojo.
In Kyoto, beneath that great and terrible shadow, Rei Mikage learned how to survive the attention that remained.
