Training Arc
Golden morning rays slipped through the old apartment's thin curtains.
The light was soft, warm, and surprisingly gentle despite the simplicity of the room.
A small bed sat against the wall — clean, neat, and well-kept despite the worn furniture.
On the bed lay a 5-foot figure, breathing shallowly, raven-black hair draped over his face.
Through the scattered strands, faint crimson light leaked from half-opened eyes.
Kai (gasping awake):
"Ah… what the hell was that speed…?
And where am I…?"
He pushed himself up slowly, scanning the unfamiliar room — but he barely managed a second look before something soft collided with him.
He was tackled.
A warm weight landed on top of him, giggling uncontrollably.
Emi (excited):
"Kai! Kai! Papa expected you!
He said he'll train us together — yah!
And you even landed a blow on Papa!"
Kai exhaled, half in pain, half amused.
The difference between Emi in combat and Emi out of combat was unbelievable — like two different people entirely.
Kai:
"So… where is this place? And where's Toj— I mean… Papa?"
Emi tilted her head at his slip but didn't question it.
Emi:
"Well… we're at Papa's apartment.
He lives here with a nice lady and their baby.
And the lady's daughter lives here too."
Kai blinked.
His mind clicked.
So the baby… that must be Megumi.
Which means Tsumiki should be around three years old right now…
The realization struck him hard.
Kai:
"Can I borrow a phone?
I need to call my mom. I disappeared for hours."
Emi's eyes widened — she had clearly forgotten about that — and she pulled him out of the room.
They walked into the living room, and the first thing Kai saw was a woman with short, spiky hair holding a baby with a blank, detached expression.
Kai (inner thoughts):
Megumi's mother… looks mid.
And the baby already has the "I'm Detached " expression…
Yep. That's Megumi. The sacrifice merchant himself.
Then he saw someone else — a petite woman with kind eyes, holding a small girl with bobbed, spiky hair.
Kai (inner thoughts):
That must be Tsumiki.
So the whole Fushiguro lineup is here…
Before he could observe further, he noticed Emi's expression shift.
Her cheerful look vanished.
Cold. Detached.
Her gaze aimed straight at the three Fushiguros.
Kai turned toward the couch as a deep voice called out.
Toji Fushiguro lay there lazily, muscular arm over the backrest, remote in hand, flipping channels every twenty seconds.
Emi softened instantly and walked over to him.
Emi:
"Papa, can Kai use your phone?
He needs to tell his mommy where he is."
Toji didn't even glance away from the TV.
He reached into his pocket, pulled out his phone, handed it to Emi.
She sprinted back to Kai and placed it in his hands.
Ring…
Ring…
Calling…
Kai (on call):
"Hey Mom...yeah, I was… playing with a friend.
I passed out from heat stroke…
Yeah, Mama… I'm at her house now.
I'll come home now."
He hung up, giving the phone back to Emi.
Kai:
"I'll be going now.
Today was… fun.
Training with you was fun."
He headed for the door — but Toji's deep voice cut through the quiet room.
Toji:
"Brat.
Be here early tomorrow.
Training starts at dawn."
Kai nodded.
Before stepping out, he caught Tsumiki peeking at him shyly from behind her mother's leg — but someone moved in front of him.
Ichika Fushiguro stood there with a warm smile.
Ichika:
"Here sweetie, let me open the door for you.
Are you Emi's new playmate?"
Her tone was gentle. Too gentle.
Kai:
"Yes. Emi is a friend."
He grabbed the door handle and closed it — directly in Ichika's face — at high speed.
Not out of rudeness.
But because of Emi's reaction toward her step family.
He stepped outside and immediately burst into motion — moving so fast that a breeze swept past people walking on the street.
He slowed only once — next to a restaurant window — and waved at a girl his age.
She giggled and waved back.
Random girl:
"Mommy, look!
I want to run like that boy!"
Father (on the phone):
"Yeah yeah, pumpkin, ask your mother im busy on an important call."
Mother:
"Sure, sweetheart.
Where's the boy?"
The girl pointed at the sidewalk.
But Kai was already gone — vanished like a gust of wind.
Random girl:
"He was right there!
He was fast… like Daddy's car!"
40 minutes later…
Kai finally reached Jujutsu High.
He walked through the gates, took a separate path toward a small wooden house.
He removed his shoes.
Prepared himself mentally for the incoming scolding.
He stepped inside.
Kai:
"Mom, I can explain. I was—"
She sat elegantly, drinking a soda, her eyes cold as ice.
Kai froze.
Ayaka:
"I hope you understand that the people who wiped out our clan are still out there.
If they learn you exist, they will take you.
And they will do terrible things to you."
A chill crawled down his spine.
But then — her expression softened.
She placed the glass down and ruffled his long hair.
Ayaka:
"I saw you playing with that cute girl.
Is she a sorcerer?
She seems like someone with Heavenly Restriction…
Is she your new friend?"
Kai nodded.
Kai:
"Yes, Mom.
She's my new friend.
Her father is—
never mind.
He's just a normal man but very talented in martial arts.
He said he'll train both of us.
So… I'll be going there tomorrow."
Ayaka's expression grew skeptical — very skeptical — but she didn't push further.
She only nodded and told him dinner was ready.
Next day..
The first rays of dawn spilled across the forest clearing, a soft golden shimmer brushing the dew-soaked grass. Despite the peaceful atmosphere, an intense pressure filled the air—sharp, alert, ready for violence. Toji stood barefoot on the dirt, arms crossed, faint steam rising off his skin from the early chill. Emi stretched her limbs beside him, silver eyes burning with excitement. I stood across from them, fingers tightening around the hilt of the training blade Toji had given me.
This has been weeks of my new life—training under the Sorcerer Killer.
And his methods were brutal.
Toji's Philosophy
Before any sparring, Toji drilled into us the foundations of his combat doctrine.
He explained that nearly every sorcerer wasted movement—exaggerated stances, unnecessary swings, excessive footwork, pointless gestures.
Toji:
"Useless movement gets you killed."
Then he demonstrated.
A small shift of his heel.
A subtle dip of his shoulder.
A minuscule twist of his torso.
Even the breeze seemed afraid to disturb him.
Toji:
"Everything you do must either build momentum or steal it.
Nothing in between."
His movements were so efficient that it was as if the air obeyed him, bending around his body.
He made Emi and I repeat the drills for hours—running, stopping, turning, swinging, jumping—over and over until our muscles burned. Each time we stopped, he corrected us with a single word.
Toji:
"Too wide."
"Too slow."
"Wasted step."
"Again."
When he finally gave us swords, it wasn't to learn swordsmanship.
It was to learn control.
Forming My Technique
As I swung the saber, I focused on channeling cursed energy through the blade—using it as a medium to stabilize my output.
Every downward arc of the sword became a training exercise.
Fill the blade with cursed energy.
Hold it.
Refine it.
Then—
Release.
I tried to recreate the feeling I had during Cleave—
that spatial fracture, that sensation of slicing space itself.
The more I practiced, the more I understood that Dismantle was forming within me—
a slashing technique derived from my earlier instincts.
And so I began cutting with smaller blades each session, reducing my dependency on them.
A saber one day.
A short sword the next.
A dagger after that.
My goal was clear:
Perform Dismantle with nothing but my hands.
And eventually… with only my eyes.
That last part would require a Binding Vow, but that was for later. For now, control was everything.
Seven days passed.
By the end of the 4th week, the smell of steel, sweat, and crushed grass had become familiar. And that's when Toji finally said the words I'd been waiting for.
Toji:
"Alright. You two can move. Time to spar.
Since this brat—" he jabbed a thumb at me "—is too much for my Mi-mi alone…
How about you both attack me at once?"
Emi and I exchanged a glance.
Then we smirked.
The Double Assault
We moved instantly.
I surged forward first, my speed 50% faster than Emi's—naturally. Then I reinforced my body with cursed energy. The leak was far less than before, finally under control. My speed jumped again.
Now I was 150% faster than Emi.
The ground cracked beneath my feet as I reached Toji in the blink of an eye. I swung my saber in a clean horizontal slice.
Toji shifted half an inch.
The blade missed by less than a finger.
I used the leftover momentum to rotate my hips, driving a secondary slash down toward his inner kneecap—one of the only weak points in the human body that could disrupt someone like him.
But Toji had already read the attack.
His body lowered with the slightest flex.
A light thump sounded beside me.
Emi arrived.
She leaped with a flying kick, the force sharp enough to break a normal man's ribs.
Toji simply raised one knee.
He stepped on the air.
Just lightly enough for the cursed-enhanced impact to lose all force.
Then his body bent backward in a perfect arc, rotating in midair. Emi's kick soared past his chest harmlessly.
I stumbled—my follow-up swing missing.
Toji, still upside down, extended both arms—
WHAP!
His open palms smacked our backs simultaneously.
We were flung across the clearing like rag dolls.
He landed perfectly upright.
Of course.
Emi and I pushed ourselves up, covered in dust, breathing hard.
She wiped her cheek and grinned.
Emi:
"Kai! Papa's too fast. We can't over-commit.
We'll have to go all out just to touch him."
I nodded.
Then I saw it—the shift in her aura.
Her irises flickered silver.
Eyes completely black.
Her legs glowed faintly with silver-white wisps of energy.
The Garcia Clan Ability — Intent (意思の閃光)
Emi Garcia's bloodline came from a hidden island protected by a natural barrier—its location invisible to outsiders unless shown by a native. The three great families on that island all possessed Heavenly Restriction, but because their island was saturated in evolved curse spirits that hunted HR users, the people had no choice but to evolve and develop special counter-abilities.
Garcia CLAN ABILITY :INTENT (意思の閃光)
"When all five senses exceed their natural ceiling, compress into one point, and align with a single purpose."
Intent is the Garcia clan's awakened sensory-fusion technique, the only "technique" that a Heavenly Restriction user can activate.
What It Is
The user pushes all 5 senses—
Sight
Hearing
Smell
Touch
Taste
past superhuman limits until they synchronize into a single hyper-sense, generating a spark of positive energy (rare for humans).
Think of it as:
Positive Energy + Sensory Overflow
It creates a burst of white lightning aura around the body or weapon.
What Intent Enhances
Damage dealt increases
Speed/acceleration increases
Reaction speed increases
Impact force increases
It ONLY enhances speed and raw physical damage, nothing else.
DAMAGE & SPEED increase
Because positive energy interacts differently depending on the opponent:
Against Cursed Spirits
+100% (double raw power)
Positive energy is lethal → full effect.
Against Sorcerers (normal users)
+55% (half again as strong)
Their CE buffers the hit partially.
Against RCT Users
+25% (one quarter increase)
Their healing potential dampens the intent impact.
Against Reversal Technique Specialists
+5% (one tenth boost)
Their mastery of positive energy cancels most of the positive energy surge.
When activated:
a bright silver white lightning sparks vein crackles across the arms and legs.
Emi's movements create thin streaks of white static
her eyes turn black and her irises silver slightly from sensory overload
Every clan technique needs risk.
Drawbacks of Intent
After activating Intent, the senses take a moment to "re-separate," leaving her vulnerable for half a second.
Using Intent multiple times in rapid succession causes severe sensory backlash:
migraine
ringing in ears
blurred vision
nausea
slowed reaction time
Overuse can lead to temporary sensory burnout, where one or more senses shut down.
But at life and death an awakening can be triggered which is rare only 20% of my the Garcia Clan can achieve this .
The Fight Resumes
We charged again.
This time, Emi overtook me—her speed doubling instantly under Intent. White static trailed behind her heels as she vanished from my side and reappeared in front of Toji.
She launched a sweeping kick with blinding speed.
Toji sidestepped by an inch.
Emi used the momentum to flip into a one-handed handstand, her free leg whipping toward Toji's thigh.
At the same moment, I threw my saber.
Toji's reaction was inhuman.
He leaned back just enough for Emi's kick to graze past, then—
CHOMP.
He caught my saber between his teeth.
Still rotating, he used his entire torso motion to fling the blade at me with monstrous force. The sword screamed through the air like a projectile.
I reached out to catch it.
A memory flashed—
a manga panel, an amplification of my technique,
I focused.
My fingertips brushed the steel—
Curse Technique: Cleave
A burst of miniature slashes erupted around my hand, forming a protective shell of spatial cuts. They softened the blade's force just enough for me to grip it without losing my fingers.
I grabbed the sword cleanly.
Then tossed it aside, where it buried itself deep into the earth with a loud THUNK.
I sprinted forward, landing in front of Toji.
He was grinning.
A wide, wild grin.
Toji:
"Good.
Now we're getting somewhere."
I burst forward—my feet shredding the dirt beneath me—as I finally reached Toji in half a step. Emi was already there. Her movements were a blur, a storm of silver-white static as she unleashed multiple strikes in rapid succession. Every kick, every chop, every sweep was perfect.
And Toji dodged all of them without breaking rhythm.
I could tell she was close to her limit—Intent only lasted two minutes, and she was already pushing 90 seconds. Her breathing was thinning. Her pupils shaking.
Kai (thoughts):
She's got seconds left. I need to push too.
I lunged in.
Toji whipped a palm toward my chest.
I twisted my wrist, reached out—
and parried.
Just a light touch.
Just enough physical contact.
And in that instant—
Curse Technique: Cleave (Low Output)
My fingers scraped across his skin as I triggered the technique.
Thin scratches split across his bicep and shoulder—shallow, but real.
Toji's eyebrows rose a fraction.
A sign of interest.
Emi used that exact moment, pushing past her pain and exhaustion. She pivoted and launched a full-force Intent-boosted kick straight into Toji's ankle. The impact cracked like a gunshot.
Toji didn't just tank the hit—
he used it.
His body spun.
Fast.
Too fast.
A tornado kick veered toward me, slicing the air open. The air pressure alone felt like a blade.
I reacted at the last second.
Both arms up.
Cursed energy flaring.
Eyes glowing crimson.
Cleave: reentry
I slashed the space in front of Toji's incoming strike—
cutting the pressure wave, diminishing the force.
It only reduced the impact by maybe 10%, but to Toji, that was enough to be surprising. I saw a flash of realization in his eyes.
He saw what I did.
Then his foot connected.
The world spun violently.
I was launched backward, crashing into the ground so hard dirt burst up around me. Pain flared through my arms—my muscles trembling, my bones rattling.
But he wasn't done.
With the remaining torque of his rotation, Toji used the momentum to drive his knee toward Emi.
She reacted beautifully.
Instead of blocking, she shifted her weight to the right—barely—and avoided most of the blow. The knee clipped the side of her hip, sending her stumbling, but it didn't break her.
She used that small misstep—
to launch an upward slash at Toji's knee with her sword.
The blade struck, just barely, drawing a thin line of red.
Returning something—no matter how small.
Emi was blasted out of the air, spinning before she crashed into the ground. But she was smiling even as she winced in pain.
Both of us were panting.
Dusty.
Bruised.
Barely standing.
Toji walked toward us with a pleased grin—one that only a man like him could make look both dangerous and approving.
Toji:
"After weeks of training, both of you can finally land one hit on me.
Even if I'm not going at 30%… that's impressive improvement."
We both smiled weakly.
Even a single scrap of praise from the Sorcerer Killer felt like gold.
For me, the feeling was deeper.
Kai (thoughts):
I know what's coming. The Star Plasma Vessel… Geto… Gojo… the future disasters. This training—it's priceless.
Landing even a scratch on Toji had taught me something crucial:
Cleave wasn't just for offense.
It could cut the pressure, the force, the impact of physical blows.
I evolved it by remembering what sukuna did, in the manag to hold a sword or weapon from yuta using cleave ...to protect and I also used the concept of infinity from gojo . but instead to reduce the impact ,since I can't use domain amplification currently but .
If I could refine that…
I could survive almost anything.
With it and by tanking the rest of the damage, even if I can just half the damage from physical attacks will be enough.
Maybe a Binding Vow would help refine that control…
Emi groaned lightly and sat up.
Emi:
"We almost got Papa… but he's too fast. Maybe we should fight each other more often!"
I glanced at her, feeling a tug of guilt.
Kai:
"Yeah… but Emi, if I fight you seriously, I can't practice my curse technique. You wouldn't be able to deal with it."
That wasn't the full truth.
The real reason was .
Fighting Toji gave me the feeling of death breathing down my neck—
that suffocating pressure that forced my Demon Cry Eyes to awaken survival instincts deeper within my body. Fighting him made me grow.
Fighting Emi… wouldn't.
She noticed my tone and puffed her cheeks slightly.
Then she grinned.
Emi:
"Okay then! We'll only use martial arts when we fight each other.
Then after… we'll fight Papa together!"
I smiled and nodded.
Kai:
"Deal."
Toji cracked his neck and looked at us like he was already planning something.
Toji:
"Well… you both better get ready. In one week, you're coming with me on a mission.
Time to see what you can do outside this clearing."
Emi's face lit up with excitement.
Mine tightened with focus.
Reality hit:
This wasn't a game.
Toji didn't do "training missions."
He did real ones.
This was a test.
A dangerous one.
But exactly what I needed.
Hours Later — Jujutsu High
Back at the small wooden house where I lived with my mother, I sat cross-legged in the back room. My eyes were closed, my breathing deep, steady.
The air in the room vibrated with cursed energy.
I began chanting quietly—
the beginning ritual for my next Binding Vow.
My heart pounded.
My cursed energy condensed.
My Demon Cry Eyes throbbed behind my closed eyelids.
I was preparing to take a step that very few have ever attempted…
a step that would either empower my technique—
or break my body.
