Chapter Text
The hospital hallway smelled faintly of antiseptic and old tile.
Yuji stood in the shadow near the wall, staring at nothing in particular while the fluorescent lights hummed overhead. The world had gone strangely quiet after the doctor finished speaking.
His grandfather was gone.
Just like that.
The words still hadn’t fully settled in his chest. They floated somewhere above his head like a sentence he’d read but hadn’t yet understood. A few hours ago the day had been normal, laughably normal.
He’d been joking around with the Occult Club, arguing about ghosts and stupid internet rituals.
Now his grandfather was dead.
And somewhere across the city, his friends might be in danger because of a cursed object Yuji had handed them.
Great. Fantastic.
What a day.
As if the universe had decided that losing one family member wasn’t enough emotional damage for a single afternoon. It had also apparently sent him two extremely weird high schoolers to stalk him through the hospital.
Both of them had black hair and they looked like they belonged in some kind of elite delinquent academy rather than a hospital corridor.
One of them, the boy with a permanently irritated expression and gravity-defying spiky hair. He stood with his arms folded, posture stiff with impatience. His dark eyes flicked occasionally toward Yuji as if measuring him for something.
The other one leaned casually against the wall beside him.
She spoke first.
“If it helps,” she said dryly, “my mother used to call me a monster.”
Yuji blinked.
He turned his head slowly toward her.
The boy, Fushiguro Megumi, he’d said his name was, looked like he physically wanted to face-palm but somehow resisted.
Yuji couldn’t help it. A laugh bubbled up in his chest, threatening to escape purely from the sheer absurdity of the situation.
His grandfather had died.
He was being chased by curse-hunting teenagers.
And now a girl he’d known for approximately ten minutes had decided the appropriate response to grief was comparing trauma.
“Yeah,” Yuji said through a wane smile. “That doesn’t help at all.”
The girl merely tilts her head slightly.
Up close, Yuji notices her eyes.
They were… striking.
Gold.
Not just light brown or hazel, actually gold. Like embered sparks caught in sunlight, flickering with an intensity that felt almost dangerous. It reminded him weirdly of fire waiting for oxygen.
Or a sleeping dragon.
“Oh. Sorry.” she says, interrupting his thoughts.
She didn’t sound sorry.
Still, Yuji appreciates the attempt. He studied her a little longer before he could stop himself.
She was… kind of incredible-looking.
Not in the flashy modern idol way some girls were.
There was something older about her beauty, sharp, elegant, almost aristocratic. Her features looked like they belonged in an old painting of some feudal princess dragged inconveniently into the twenty-first century.
Her hair fell like black silk down her back, two loose strands framing her face in a way that somehow made her look even more composed.
Yuji felt heat crawl up the back of his neck.
Kami, he was such a nerd.
He quickly looked away and scratched his cheek, hoping desperately she hadn’t noticed him staring.
Fushiguro definitely had.
The look he gave Yuji was so pointed it might as well have been verbal.
“It’s okay,” Yuji muttered quickly, suddenly unsure how he’d somehow become the one doing the consoling.
Fushiguro exhaled through his nose and shook his head before turning to the girl.
“What are you doing here anyway, Azula?” he asks flatly, “This is my mission.”
Azula.
The name fit her in a strange way.
She glanced at him with immediate disdain. The expression was so sharp, so completely unimpressed, that Yuji had to fight down another laugh. The contrast between her delicate face and the absolute venom in her eyes was weirdly… endearing.
She lifted her phone.
“Because,” she said, tone dripping sarcasm, “our dear sensei wouldn’t stop whining about his worry for ‘our precious Megumi.’”
She used her free hand to make exaggerated quotation marks in the air.
Yuji leaned slightly closer to see the screen.
Displayed proudly was a photo of a much younger Megumi Fushiguro.
He looked furious.
Someone, clearly the same “sensei”, had drawn flowers all around him in bright pastel colors. Underneath the picture, written in bubbly text, were the words:
OUR PRECIOUS MEGUMI
Yuji stared.
“…Is that you as a kid?”
“I’m going to kill him,” Megumi said immediately.
He lunged for the phone.
Azula moved before Yuji even fully registered the motion.
Her arm shifted an inch, barely moving and Megumi’s hand swiped through empty air. She steps smoothly out of his second attempt with almost insulting ease.
“Hands off,” she said coolly.
“And I’d love to see the day that happens.” Megumi flipped her off.
“You are just like dad.”
Azula’s expression brightened instantly.
“I am! Thank you!” She chirps surprisingly pleased, didn’t he abandon them or something?
Yuji looked between them.
Then back again.
And suddenly something clicked. The resemblance was subtle but unmistakable once you noticed it.
The sharp jawline, the same dark hair.
“…Wait,” Yuji said slowly, pointing between them. “Are you guys…what? twins?”
Azula scoffs like he asked if the sky was red.
“No.” Megumi responded looking insulted at the thought.
Azula answers for them, “Our father just slept around.”
“Like… A lot.” She gestured lazily between them. “Getting two women pregnant around the same time, I think Megumi’s mom and our dad had some sort of threesome with my mom.”
Yuji blinked. She doesn’t hold back on information.
“Azula.”
“…Oh.”
She continues unbothered by the fact she is over sharing to a stranger, “My mother dumped me on his doorstep after three years,”
“After the neglect and abuse got boring, I guess.”
Yuji opened his mouth.
Closed it.
Opened it again.
“…I’m-”
“Then dad disappeared too,” she finished.
Yuji winced.
“That’s… kinda messed up.”
He hadn’t meant to say it out loud.
Azula shrugs like she was talking about the weather, “Parents are useless anyway.”
Yuji hesitates.
He’d been raised by his grandfather his entire life.
His father and mother were… well. Gone.
Either dead or disappeared, he didn’t really know.
So technically he couldn’t argue with her.
Megumi glanced up at the wall clock.
His patience had clearly reached its limit.
“Great,” he said flatly. “We all bonded over trauma.”
He turned toward Yuji.
“Can we go finish this now?”
Yuji stared at both of them.
One looked like she’d happily start a war just to prove she could win it. The other looked like he’d already accepted the world was terrible and planned to punch it anyway.
And somehow… he feels a kinship building.
Yuji sighs, wishing and willing’ away all the stress of today.
“…Yeah,” he said.
He pushed himself off the wall.
His grandfather’s last words echoed faintly in the back of his mind.
Help people.
“…Let’s go.”
The hospital doors slid shut behind them with a soft mechanical hiss. Cool night air brushed Azula’s face as she stepped onto the sidewalk. Tokyo stretched out in glittering veins of neon and headlights, the distant rush of traffic humming like a restless ocean.
The world here never truly quieted.
She had noticed that quickly after being reborn.
Even at night this civilization buzzed with movement.
No torches, or oil lanterns anymore.
No silent docile palace courtyards.
Just endless electricity and noise.
Azula slipped her hands into the pockets of her school jacket and followed a few paces behind the boys. The pavement reflected colored light from vending machines and street signs as they walked toward the school.
Yuji Itadori walked ahead of them, shoulders slightly hunched, hands shoved deep into his hoodie pockets.
Grief.
Azula recognized it immediately.
Loss had a posture.
Zuko loved to use it, especially when their mother abandoned them. He carried it in their spine like a weight pressing down on the back of their neck.
Why bother grieving for someone who abandoned you?
Megumi walked beside him, voice flat and businesslike as he explained curses with the same exhausted tone he used for everything.
“Your friends most likely have opened the seal on a cursed object,”
Megumi said. “That will attract curses.”
Yuji nodded quickly, processing it with surprising speed.
“So we just go beat it up and grab it back?”
Azula raised an eyebrow.
Most civilians did not respond to supernatural explanations with this level of casual acceptance.
They screamed.
They demanded proof.
They fainted.
This one simply… recalibrated his priorities.
Interesting.
She studied him from behind as they walked.
Rebirth had been unpleasant.
Dying had been worse.
The last thing Azula remembered of her previous life was screaming. Her own voice echoing against the cold stone.
Chains around her wrists.
White walls and unadulterated humiliation.
The Fire Nation princess, the prodigy who had been raised to rule the world, had collapsed into madness before ever reaching the throne.
Her final moments had not been glorious.
Then darkness.
And then…
A new body.
A new world.
New way of energy.
No Fire Nation..
Just a small apartment and a tired woman who clearly hadn’t planned on motherhood.
Azula had adapted.
She always adapts.
By the time she was three she had already concluded that modern society was bafflingly inefficient. By five she understood that power still existed here, it simply wore different clothes.
Money, Influence, Information.
And eventually…
Cursed energy.
The euphoria of regaining her bending was therapeutic, the years of isolation from her bending after that hypocritical avatar stole her bending.
She isn’t ashamed to admit she cried the first time she had felt it again, the same essence deep in her chest had sparked with recognition and with more.
She knew instinctively that her bending has changed fundamentally, but has grown more potent and powerful.
Power shaped by will.
Once she understood it, everything fell into place. Even in this strange world, she remained what she had always been.
A prodigy among prodigies.
Which was why meeting Megumi had been…tolerable.
She glances at him as they walk. Her half-brother was cynical, quiet, and unimpressed by most of her theatrics.
But he had something she respected.
Backbone.
Unlike Zuko.
The thought tugs faintly at her lips.
Megumi glanced sideways at her.
“Stop smiling like that.”
The grin grows, “Like what.”
“Like that.”
The wave of cursed energy intrudes on their conversation and as they arrive at the school gate. The building stood quiet beneath the night sky, its dark windows staring down like hollow eyes.
There is a faint scream that echoes towards them as a figure runs across one of the windows.
Yuji didn’t hesitate.
“My friends are probably inside!”
He took off running.
Megumi groaned and followed.
Azula walked behind them at a slower pace.
She could already feel it.
Cursed energy wrapped around the building like rot creeping through wood.
Disgusting.
Inside the gymnasium the air felt thick.
Yuji burst through the doors.
“Sasaki! Iguchi!”
Something shifted in the shadows near the stage.
A curse unfolded itself from the darkness.
It was a grotesque thing, limbs too long, joints bending wrong, skin sagging like melted wax. Its mouth stretched open in a shriek that scraped across the air.
Yuji froze.
Megumi stepped forward immediately, hands already forming signs to summon his shikigami.
Azula leaned casually against the doorway.
She watches in fascination as the curse lunges towards Yuji who reacts instantly jumping into the air and arcing his foot in a downward motion slamming into the curse with a drop kick so powerful the impact cracked through the gym like a thunderclap.
The creature breaks through the floor and slides across the hallway. It smashed into a row of lockers hard enough to dent the metal. Azula blinks and waves the construction dust out of her face.
She notices Megumi doing the same.
Yuji landed on his feet, staring at his hands with a look of wonder.
“…Did that work?”
Azula straightened slowly.
He had used no cursed energy, not even a trace.
Yet the strength behind that strike had been…
Her eyes sharpened.
Comparable to Maki Zenin, even without training.
Fascinating.
The curse screeched and lurched upright again.
Yuji grinned suddenly, adrenaline replacing hesitation.
“Oh man!” he said, turning toward them excitedly. “Did you see that?! I actually-”
The curse’s arm stretched unnaturally behind him.
Megumi’s eyes widened.
“Itadori-!”
Azula moves before she realizes. Her foot snapping up into a familiar upward motion in a swift smooth and precise move.
Cursed energy flared along her leg.
Her familiar and so beautiful, blue fire ignites instantly. She then kicks down and a crescent arc of flame sliced through the air like a blade.
It all happens in less than a second.
The curse’s arm is then separated from its body with a scorching wet boiling sound before it could reach Yuji.
The severed limb still burning dissolved into ash before it hit the floor. The curse rears back and screams as the blue flames attached to its stump continue to burn its flesh. Nothing it’s doing can put out her flames.
Yuji turned just in time to see the remains disintegrate.
“…Whoa.”
Azula lowered her leg.
The smell of scorched curse lingers in the air as the thing withers in misery.
Megumi sighed.
“You turned your back on it.” Yuji scratched his cheek sheepishly, in contrast with the screeching.
“Right. Probably shouldn’t do that.”
The curse howled in pain, crazed fury, its remaining limbs writhing and diving for a strike. Megumi’s divine dogs are already lunging forward, tearing into its limb while he prepares another technique.
Azula barely paid attention and her gaze rested on Yuji instead. He already squared up again, fists raised, eyes bright with reckless determination.
Most civilians would still be screaming.
He looked excited.
Azula stepped closer, studying him openly.
“You’re strong,” she said.
Yuji blinked.
“Oh, uh, thanks?”
She tilted her head thoughtfully.
“Yes,” she said after a moment. “You and I should probably produce very powerful offspring.”
Silence.
Yuji’s face turned bright red.
“W-WHAT?!”
Megumi slammed a hand over his face. His dogs keeping the curse distracted at the moment.
“Azula.”
“What?” she said calmly.
“You can’t just say things like that.”
“Why not?”
“You met him ten minutes ago.”
“That’s irrelevant.”
Yuji looked like his brain had stopped functioning.
“I just punched a monster!”
“Yes,” Azula said approvingly. “Very impressive.”
Megumi groaned into his palm.
“This mission was a mistake.”
“Now who might you-”
The sentence never finishes.
Azula’s foot cuts through the air where his head had been a fraction of a second earlier. The kick whistles past his ear with enough force to fracture bone. Sukuna bends backward just enough to let it pass, his body folding with lazy grace as if he had expected it.
The instant his spine straightens again, her fist is already driving toward his throat.
Precise and efficient.
A killing strike.
Sukuna slips aside, her knuckles grazing his jaw as her knee follows an instant later, aimed perfectly for the floating rib beneath his heart. If that strike landed cleanly it would collapse a lung.
He twists his hip and lets it pass, sliding around her like water around stone.
Interesting.
Very interesting.
Behind them the other boy -Megumi- has dropped into a crouch, preparing something with his shadows.
Sukuna ignores him completely.
This one is far more entertaining.
The girl slides back across the gym floor, landing lightly on the balls of her feet, golden eyes narrowed as she recalibrates. Sukuna can practically see the calculations happening behind that gaze.
A strategist.
Not just a fighter.
He laughs, a delighted rasp that echoes across the empty gymnasium.
“You’re fun.”
Her expression doesn’t change.
She circles him slowly.
Every step is measured. Every breath is controlled. He can tell already she’s probing his movements, mapping out his rhythm.
Delicious.
He hasn’t felt this entertained in decades.
“You modern sorcerers,” Sukuna says, spreading his arms slightly, voice dripping with mock grandeur, “aren’t the complete disappointments I expected.”
His eyes gleam.
“Come now.”
His grin widens.
“Show me something worthwhile, girl.”
Her brow twitches.
‘Ah.’
There it is.
Pride.
The irritation sharpens her cursed energy instantly, and Sukuna feels the pressure shift in the air around her like the moment before a thunderstorm breaks.
“You asked for it.”
She vanishes.
Not literally, but the speed is impressive enough that the human eye would struggle to follow it.
Sukuna notices the trick immediately.
Flame.
Incredible.
The instant her foot strikes the floor, a burst of fire erupts behind her heel like the ignition of a rocket. The explosion doesn’t scatter randomly, it funnels, compressed by her cursed energy into a focused thrust that launches her forward.
Propulsion.
Sukuna’s grin widens.
‘Clever girl.’
She’s on him in the next heartbeat.
Her arm carves through the air, blue flame trailing the motion like a painter’s brush across a canvas. The fire follows the exact geometry of her strike, not wild or explosive but shaped into a tight, crescent arc that slices toward his neck.
Beautiful.
Truly beautiful.
Sukuna ducks beneath the flaming blade, heat licking across his cheek as it passes. The flames aren’t normal fire either, he can feel the density in them, the compressed cursed energy stabilizing the combustion.
They burn hotter.
Cleaner.
More obedient.
He allows himself a moment of genuine appreciation.
“I’ve seen many flame techniques,” he muses aloud, sliding past another kick. “But yours…”
Her heel whistles toward his temple.
He leans aside and lightly taps her leg away.
“…has artistry.”
Her response is a spinning backhand wrapped in a spiral of blue fire.
Sukuna catches her wrist this time, examining the flames curling around her arm with clear fascination before casually kicking her in the stomach and sending her skidding backward across the gym floor.
She flips midair and lands cleanly on her feet.
Not bad.
Not bad at all.
But something else pulls at the edge of Sukuna’s awareness.
The brat.
Yuji’s soul is fighting back.
Annoying.
He can feel the vessel resisting, the boy’s consciousness clawing its way toward the surface again like a stubborn weed refusing to die.
Irritating timing.
Sukuna rolls his neck lazily and smirks.
“Is that all?”
Azula straightens slowly.
Blood runs from a shallow cut on her lip where his knuckle clipped her cheek during the exchange. She wipes it away with the back of her hand, eyes gleaming not with fear.
…but excitement.
“Oh,” she says.
A slow grin spreads across her face.
“I’ve got more.”
Sukuna’s interest sharpens immediately.
Good.
‘Show me.’
She shifts her stance.
And something changes in the air.
The cursed energy around her stops behaving like fire.
Instead it begins to separate.
Sukuna’s eyes narrow with intrigue as he watches the technique unfold.
Her breathing slows.
One hand rises.
Two fingers extend.
The other arm pulls back across her body in a deliberate motion, carving a line through the air as if she’s drawing an invisible circle around herself.
Cursed energy begins to divide along that motion.
Positive.
Negative.
Two currents sliding apart like opposing rivers.
Ah.
Recognition sparks instantly.
Lightning generation.
But the method-
Sukuna leans forward slightly.
-is exquisite.
Most lightning techniques rely on brute compression of cursed energy until the discharge occurs naturally.
This is different.
Her arms move slowly, almost like a dancer performing a ritual. Each motion separates the energy further, pulling opposing charges apart along the pathways of her body.
The air begins to vibrate.
Not loudly.
But enough that Sukuna can hear it.
A faint high-pitched hum as static begins to crawl across the floor.
Tiny arcs of electricity flicker between Azula’s fingertips, blue-white sparks snapping violently as the energy difference builds.
The atmosphere tightens.
The scent of ozone spreads through the room.
Sukuna’s grin becomes almost feral.
“Now that…”
He chuckles softly.
“…is magnificent.”
The charge intensifies.
Her hair begins to lift slightly as the electric field builds around her body. The blue flames that once clung to her arms now twist into thin streams of plasma as the heat and voltage combine.
She draws her hands together slowly.
The electricity screams louder.
Between her fingertips, a spear of pure lightning begins to form…brilliant, violent, unstable.
Even Sukuna can feel the destructive potential in that strike.
Yes.
‘Yes.’ This is what he wanted.
A true sorcerer’s technique.
His laughter echoes across the room.
“Do it,” he says eagerly.
“Show me.”
Azula’s golden eyes sharpen.
Lightning gathers at her fingertips…
And then-
“WHOA WHOA WHOA WAIT-!”
The cursed energy collapses instantly.
The lightning sputters out as Yuji Itadori violently reclaims control of his body.
Sukuna’s expression twists into pure irritation as his vision jerks sideways.
Yuji throws his hands up frantically.
“DON’T KILL ME!”
The tension in the room snaps like a broken string.
Azula blinks.
Megumi freezes.
And a cheerful voice suddenly drifts down from the gymnasium ceiling.
“Well,” the voice says casually, “this looks like fun.”
A tall man with white hair stands casually on the rafters above them, hands in his pockets.
Satoru Gojo tilts his head slightly, a grin tugging at his lips beneath the black blindfold.
“Did I miss anything interesting?”
