Jujutsu Kaisen Sakura (Kura) Geto: 23, light brown hair, green eyes, 5’3, 130lbs. Sister to Suguru Geto. This is after his death in 2017. Takes place during the events in 2018. Best friends with Satoru Gojo.

Chapter 2: Impact: The Curse That Followed Them Home

The world was a car alarm.

A high, piercing shriek that sawed through the meat of his brain. Then came the other sounds, layered over it like a sick symphony: the hiss of steam from a ruptured radiator, the slow tink-tink-tink of cooling metal, the patter of rain on shattered glass.

His vision righted itself. He was suspended upside down by his seatbelt, the ceiling—now the floor—pressed close to his face. The car was a ruined chrysalis, the streetlights outside casting long, distorted shadows through the spider-webbed windows. His Infinity had activated on instinct, a hair’s breadth from his skin, shielding him from the full force of the impact but not from the physics of the spin. His head throbbed.

Nanami.

He craned his neck. Nanami was slumped forward against the deflated airbag, a dark trickle of blood running from his hairline down his temple. Unconscious, but Gojo could see the steady, irritated rise and fall of his chest. Alive. Annoyed, probably, even in unconsciousness.

Kura.

He twisted the other way.

She was sprawled across the inverted ceiling, her body limp. The violent flip had thrown her from the back seat like a ragdoll. Her light brown hair was fanned out around her head, wet with rain leaking through the shattered window. Her green eyes were open, staring glassily at the crushed roof above her. Unblinking.

And her neck.

Gojo’s own breath stopped in his throat.

It was wrong. The angle was all wrong, a harsh, unnatural twist that made his stomach lurch. One of her arms was pinned beneath her at a position no joint should allow.

The world narrowed. The car alarm faded into a dull, distant thrum. The hissing steam, the rain, Nanami’s breathing—it all receded, swallowed by a sudden, white-noise void.

Kura.

Suguru’s little sister.

The kid who used to hide behind her brother’s legs and glare at him with those too-sharp eyes. The teenager who’d shown up at his door in the rain after the world had gone to shit, suitcase in hand, face pale and set, saying nothing. The woman who’d stood her ground in a factory mere hours ago, pushing her body past its limits, who’d kissed Nanami with such fierce desperation, who’d looked at him in the bathroom with a brokenness he recognized because it lived in him, too.

He’d promised. Not out loud, never out loud, but in every fibre of his being. After Suguru, after everything, she was his to protect. She was the one piece of his best friend he could keep from turning to ash in his hands.

And now she was lying broken in the wreckage of a car because he’d been distracted, because he’d felt something in that factory and hadn’t pushed it, because he’d been lost in his own fucking head.

A sound escaped him, not a word, just a sharp, punched-out exhale.

He fumbled for the seatbelt release. His hands, the hands that could warp space, felt clumsy and alien. The click was too loud. He dropped, landing in a crouch on the ceiling beside her. Glass crunched under his shoes.

“Kura.” His voice was a dry rasp. He touched her shoulder. Cold. “Kura, open your mouth and say something stupid. Call me an idiot. Do it.”

Nothing. Her skin was cool where his fingers brushed her neck, feeling for a pulse. He couldn’t find one, but his own heartbeat was a deafening drum in his ears, masking everything. His Six Eyes saw the world in cursed energy, and around her, it was a dim, fading aura, sputtering like a dying candle.

Panic, cold and razor-sharp, sliced through the void in his mind. It wasn’t the strategic fear of a lost battle. This was primal. This was a hole tearing open in the floor of the universe.

“No. No, no, no.” He gathered her up, his movements frantic. He cradled her against his chest, his hand coming up to support her head. The wrong angle of her neck was a visceral horror against his palm. “Come on. Come on, you stubborn little—” He couldn’t even finish the insult. It felt like blasphemy.

He poured cursed energy into her, a reckless, blazing torrent. It was brute force healing, something he was terrible at, but it was all he had. The energy should have sparked something, anything. It flowed into her and… dissipated. Like pouring water into sand. He did it again, gritting his teeth, the blue glow of his power illuminating the crushed cabin, glinting off the shards of glass in her hair. Nothing. Her lifeless form absorbed it and gave nothing back.

“Don’t you do this.” The words were a raw whisper against her temple. “Don’t you fucking dare. You don’t get to leave. Not you. I forbid it.”

A memory flickered, unbidden: Suguru, smiling that tired smile, handing him a soda. “Look after her for me, Satoru. She pushes too hard.”

He hadn’t. He’d failed. Again.

His vision blurred. He blinked, and a hot streak cut through the grime on his cheek. He never cried. He made jokes. He wore blindfolds. He didn’t—

A tiny, almost imperceptible crackle.

It wasn’t a sound from outside. It came from within the body in his arms. A faint, wet snap.

He looked down. Her neck.

The impossible angle was shifting. Not with the laxness of a broken thing settling, but with a deliberate, ghastly tension. Tendons tightened under her pale skin. Vertebrae, visible through the manipulation of cursed energy to his Six Eyes, were sliding, twisting, re-knitting themselves with a series of minute, sickening pops.

He stared, frozen.

A choked, wet gasp ripped from Kura’s throat. Her body arched violently in his arms, a seizure of raw, biological repair. Her eyes, once glassy, screwed shut in agony. Color rushed back into her face, a painful-looking flood of pink. The arm pinned beneath her twisted back into place with an audible click.

Her cursed energy, which had been guttering out, suddenly flared. Not a healing, gentle light, but the harsh, internal burn of her unique technique—the one she used to enhance her speed and strength. She was using it in reverse, turning it inward, forcing her own body to mend its catastrophic wounds at a speed that should be impossible.

It was consuming her. He could see it. The flare was burning up her reserves, eating into her core. She was trading her life force, her very potential, for this single, desperate act of survival.

She was killing herself to keep living.

“Stop,” he breathed, his arms tightening around her as she shuddered through the trauma of rebirth. “Kura, you have to stop it.”

Her eyes flew open. They were fully conscious, fully aware, and filled with a world of pure, unadulterated pain. She met his gaze, her breath coming in short, ragged pants. A trickle of blood escaped the corner of her mouth.

A weak, terrible smile touched her lips. “Told you… it was fine,” she managed, her voice a wrecked scrape of sound.

Then the light in her eyes dimmed again, not into death, but into a deep, exhausted unconsciousness. The violent mending had stopped. Her neck was straight. Her arm was aligned. But the cost was written in the ashen pallor of her skin, the alarming shallowness of her breath.

Gojo held her, his own breath returning in a sudden, shuddering wave. The panic wasn’t gone. It had simply morphed into a colder, more ferocious thing. Relief so sharp it hurt, and a fury so deep it vibrated in his bones.

Someone had done this. Someone had crashed their car. This was no accident.

He looked up through the shattered windshield, his Six Eyes scanning the rain-slicked, sirens-distant night. They’d felt a drain. And now this.

He gently laid Kura back down, arranging her as comfortably as he could on the ruined ceiling. He stood up in the wreckage, glass and metal bending away from the space around him, repelled by Infinity. He turned his head, the blindfold gone, his eyes blazing with a cold, celestial light.

The chapter was over. The hunt was beginning.

Rain fell through the shattered roof of the car, each drop sizzling into vapor a millimeter from Gojo’s skin. His Infinity was a perfect, furious sphere. He heard Nanami groan, a gritty, pained sound of someone clawing back to consciousness.

“Report,” Nanami’s voice was slurred but demanded order from the chaos.

“Alive. Both.” Gojo didn’t turn, his gaze scouring the night. “Kura’s down. She… put herself back together.”

Nanami struggled with his seatbelt latch. It clicked. He fell onto the ceiling with a solid thud, swearing lowly. He pushed himself up, one hand going to his bleeding temple. His glasses were cracked. He saw Kura’s prone form, the unnatural pallor of her skin, the blood on her lips but the straight line of her neck. His analytical mind processed the contradiction instantly.

“How.”

“Her technique. Turned inward.” Gojo’s voice was flat, devoid of its usual musical taunt. “Burned her reserves to do it. Idiot.”

“Pot,” Nanami muttered, wincing as he touched his head wound. He crawled over to her, his movements stiff but deliberate. Two fingers pressed to her throat. A thread-like pulse fluttered against his skin. “Stable.But depleted. Severely.” He looked up at Gojo’s rigid back. “The driver?”

“Gone.” Gojo’s Six Eyes dissected the scene. The skid marks weren’t from panic braking. They were a precise, intentional arc. The impact point was calculated—a T-bone designed to spin them, not crush them. To disorient. “This wasn’t an accident.”

“Obviously.” Nanami shrugged out of his suit jacket, rolling it to cushion Kura’s head. His hands were steady, his focus absolute. “A diversion? Or the main event?”

A flicker of energy, faint and wrong, brushed against Gojo’s perception. It came from a service alley across the street, a brief spike like a camera flash behind closed eyelids. It tasted metallic.Hungry. It was the same jittery signature from the factory, the same ‘drain’ Kura had felt.

“Main event,” Gojo said.

He took a single step. He didn’t walk. Space compressed, folded, and he was simply there, across the wide avenue, at the mouth of the damp alley. Rain dripped from a rusted fire escape overhead. The air smelled of wet garbage and ozone.

The alley was empty.But not clean. His eyes saw the ghost of it. A residue of reversed cursed energy, sticky and sour, clung to the bricks where someone had leaned. It was a healing technique’s fingerprint, but twisted, somehow parasitic. This was what had drained the curse at the factory. This was what had siphoned energy from the school. Someone was using reversed cursed energy not to mend, but to steal.

To fuel what?

“You’re a fast little cockroach,” Gojo said to the empty space, his voice echoing off the wet walls. He wasn’t smiling. “But you left a stain.”

Back at the wreck, Nanami had Kura cradled in his arms, her head lolling against his shoulder. He looked every bit the salaryman in a shredded shirt, holding a broken doll. The dissonance was stark.

“Well?” Nanami asked, his eyes scanning the darkness for threats.

“They’re gone. For now.” Gojo’s gaze snapped back to Kura. A new, colder fear cut through the anger. Her self-repair was a monstrous strain. What if it had eaten more than just her energy? What if it had consumed part of her technique’s foundation, her very potential? The thought was a void. “We need Shoko. Now.”

Sirens finally warbled close, blue and red lights painting the rain in garish streaks. Gojo ignored them. He moved beside Nanami and placed a hand on his shoulder. “Don’t throw up on my shoes, Nanamin. You know how you get with this.”

Nanami’s retort was lost in the gut-churning twist of spatial distortion. The alley, the wreck, the sirens—they vanished, replaced by the sterile, antiseptic calm of Shoko Ieiri’s morgue. The transition was instantaneous.

The doctor was leaning over a stainless steel table, a cigarette dangling from her lips. She didn’t startle. She just took in the sudden arrivals: the powerful sorcerer vibrating with silent rage, the pragmatic one bleeding and holding a limp colleague, the woman herself pale as the sheets on her tables.

“Business or pleasure?” Shoko asked, her voice a dry monotone. She stubbed out the cigarette.

“Neither.” Gojo’s word was final. “Fix her.”

Nanami laid Kura gently on a clean exam table. Shoko was already moving, her hands clinical and swift, checking pupils, pulse, the alarming coolness of her skin. She peeled back an eyelid, then paused, her professional detachment faltering for a fraction of a second.

“Her eyes are burnt,” Shoko stated.

Gojo went very still. “What.”

“Metaphorically. The vessels are fine.” Shoko pointed a small penlight. “But the cursed energy pathways behind them are… frayed. Overstressed. Like she tried to channel a sun through a drinking straw.” She looked at Gojo, then at Nanami. “What the hell did she do?”

“She fixed a broken neck,” Gojo said, the words hollow. “In about twelve seconds.”

Shoko blinked slowly. She placed a hand on Kura’s sternum, closing her own eyes to feel the flow within. A long silence followed, broken only by the hum of refrigeration units. “She didn’t just burn reserves,” Shoko finally said, opening her eyes. “She scorched the well. The recovery won’t be days. It could be weeks before she can safely channel anything more than a flicker.”

The news landed in the quiet room like a stone. Gojo turned and walked to the far wall, leaning his forehead against the cool tile. The weight of it pressed down.Weeks. In their world, weeks was a lifetime of vulnerability.

Nanami accepted a damp cloth from Shoko and pressed it to his own head wound. “Will there be permanent degradation?”

“Unknown.” Shoko began setting up an IV line. “She forced a miraculous-grade healing.The body paid. The technique might have, too. We’ll see when she wakes up.” She glanced at Gojo’s back. “Someone tried to kill you all.”

“They weren’t trying to kill,” Gojo corrected, his voice muffled by the wall. He turned around. His eyes were visible, and they were terrifyingly clear. “They were trying to create. An event traumatic enough to force a massive, uncontrolled output of cursed energy. A feast.”

He pushed off the wall. The casual grace was back, but it was now the grace of a predator on a wire. “The crash was the starter pistol. They were waiting in that alley to harvest what came next. Probably what they’ve been doing all along—poking high-energy targets to make them bleed power, then scooping it up.” He looked at Kura’s still face. “They just didn’t count on her bleeding inward instead of out.”

Nanami adjusted his cracked glasses. “A sorcerer who consumes the energy of others. A parasite.”

“A vulture,” Gojo corrected, a sharp, humorless smile touching his lips. “Circling the wounded.” The smile vanished. “And they’ve been at the school. They know where we live. They know our patterns.”

Shoko finished with the IV, her expression grim. “She needs rest.Absolute rest. You two look like you need a battlefield and a name.”

“We have a signature,” Gojo said, his gaze drifting to the door, towards the city. “And now I’m annoyed.”

Nanami stood, discarding the bloody cloth. The gash on his head had already clotted. “A plan requires more than your annoyance.”

“First, we secure the school.” Gojo’s tone left no room for debate. “Then, we go shopping. I need a new car. And after that,” he finally looked at Nanami, the cosmic blue of his eyes blazing with a cold, singular promise, “we set a trap. And we use the thing they want most as bait.”

He meant Kura. The realization settled between them, heavy and unspoken.

Nanami’s jaw tightened. He gave one slow, precise nod. It was not agreement with the method. It was an acknowledgment of the only path forward.

In the hall, the flickering fluorescent light buzzed like an insect. Gojo paused, one hand on the doorframe. He looked back into the room, at the small figure on the table connected to tubes and monitors. His usual mask was gone, sandblasted away by the night’s violence. What remained was a raw, relentless focus.

The vulture was still out there, hungry. And now the strongest sorcerer knew it was being hunted.

He would turn the city inside out to find it.

He would turn the city inside out to find it.

A few days later, sound returned first.

It was a steady, rhythmic beep, sterile and insistent. Then came the low hum of air conditioning, a vibration she felt through the mattress before she heard it. Smell followed—antiseptic, crisp linen, the faint, flat scent of recycled air. A hospital. The knowledge was a dull thud in her consciousness.

She tried to open her eyes.

Nothing changed.

Panic, cold and immediate, slithered up her spine. She squeezed her eyelids tight, then forced them open again. A murky, soupy grayness greeted her. Blobs of darker shadow swam in a vague, lightless fog. She could perceive light, a general direction of brightness, but no shapes, no edges, no definition.

She couldn’t see.

Her breath hitched, a sharp, ragged sound in the quiet room. She tried to sit up, but her body was a distant, leaden thing. A dull, deep ache pulsed in her neck, her shoulders, a memory of violence etched into her bones. The IV tugged at the back of her hand.

The beeping accelerated, matching the frantic rhythm now building in her chest. She tried to lift a hand to her face, to rub her eyes, to confirm this was just some sleep crust, some temporary blur. Her arm moved an inch before a wave of profound weakness washed over her, making her gasp.

She was blind. She was broken. She was trapped in this bed, in this vague gray void.

“Hey. Breathe.”

The voice came from her right, close. Gojo. It wasn’t his usual playful lilt. It was quiet, measured, a deliberate calm poured over something tense.

It didn’t help. Her lungs were cement sacks. She sucked in a breath that caught in her throat, producing only a thin wheeze. The beeping became a frantic, continuous chime. Shadows moved in the gray—one leaning over her, a hand, maybe—but she couldn’t make it out. The ambiguity was worse than total darkness.

“Kura.” His voice was firmer now. A hand—she thought it was his—settled on her forearm. The touch was shockingly warm. “You’re in Shoko’s clinic. You’re safe. Your eyes are… they’re recovering. It’s temporary.”

Temporary. The word meant nothing. The gray fog was everything. She tried to speak, to demand answers, but another choked sound was all that emerged. Her heart was a wild animal throwing itself against her ribs.

“Nanami. Get Shoko. Now.” Gojo’s order was clipped, directed away from her.

Another shadow, taller and more rigid, detached itself from the blurry wall and moved swiftly out of her limited perception. The door swished open and shut.

“Listen to me,” Gojo said, his hand tightening on her arm. “You used your technique. You turned it all the way inward to fix… to fix what got broken in the crash. You fried your own pathways. Shoko said it would be like this for a bit. Your sight is coming back. It’s just slow.”

A crash. The word unlocked a flood of sensory ghosts—the scream of metal, the dizzying spin, the impossible, wrenching pain in her neck. The feeling of something inside her snapping into place, over and over, burning through her like a fuse.

She had done that. She had mended herself. She had poured every ounce of her will into not dying, and this was the change.

The beeping was a relentless alarm. Her breaths were short, useless gulps. The gray world began to tilt, a nauseating swirl of nothing.

“You’re hyperventilating. You’re going to pass out again.” His voice cut through the rising static in her head. “I need you to match my breathing. Can you do that? Out.”

He took an exaggerated, slow breath in, his hand still a firm anchor on her arm. She tried to follow, but her chest seized. A sob racked her, dry and painful.

“Try again,” he insisted, no pity, just a stark command. “In.”

She dragged air in through her nose, a shuddering, broken imitation of his calm rhythm.

“Out.”

She let it out in a rush. They repeated it. Again. The beeping began to slow, incrementally, from a panicked whine back to a frantic trot. The gray world settled, stopped its sickening spin. Tears, hot and pointless, spilled from her unseeing eyes, tracing paths down her temples into her hair.

“Good,” he said, and the word was so un-Gojo-like in its softness it almost made her panic again. “Just keep doing that.”

The door swished open. New footsteps, lighter, clicked across the floor. A new blurry shape entered her gray field.

“About time,” Gojo said, but his tone lacked its usual edge.

“I was two doors down,” Shoko Ieiri’s dry voice answered. The beeping monitor was silenced with a click. “Welcome back, Geto. You gave us a scare. Mostly him. He’s been insufferable.”

Kura tried to form a word. “C-can’t…” she rasped, the sound barely recognizable as her own.

“See? I know.” Shoko’s shape moved closer. A cool hand touched her forehead, then gently pulled down an eyelid. A penlight shone, and the vague brightness intensified, but still resolved into nothing. “The physical structures are perfect. Your cursed energy pathways to your ocular nerves are… let’s call them ‘scorched.’ You overloaded them. They’re healing, but it’s like regrowing a forest after a wildfire. It takes time.”

“How long?” The question came out as a desperate croak.

“Days. Maybe a week. It’ll come back in pieces—light perception, then shapes, then detail. Don’t force it.” Shoko’s hand retreated. “The rest of you is in better shape than you have any right to be. Severe cursed energy depletion. You basically drained your tank and then sucked on the fumes.”

“The crash,” Kura managed, focusing on the solid pressure of Gojo’s hand on her arm to keep the gray panic at bay.

“Wasn’t one,” Gojo said. His thumb moved, a small, almost unconscious stroke against her skin. “Someone rammed us on purpose. A welcome-to-the-neighborhood gift.”

Nanami’s voice came from nearer the door, his presence a solid, reassuring block in the blur. “The driver was a non-sorcerer. A hired weapon, likely. The signature we’ve been tracking was nearby, waiting. We believe the intent was to cause a massive, traumatic output of cursed energy for harvest.”

“A vulture,” Gojo added, and she could hear the cold smile in his voice. “Circling.”

The pieces, foggy and disconnected, began to click into a terrifying whole. The factory. The weird drain. The school. They’d been watching. They’d hunted them. Her breath hitched again, but she forced it down, clinging to Gojo’s earlier rhythm.

“They failed,” Nanami stated. “Because you redirected the energy inward. You denied them their feast.”

She hadn’t been brave. She’d been desperate. The memory was a physical nausea. “Did they…?”

“We’re handling it,” Gojo cut in, his tone leaving no room for doubt. Or argument. “Your only job is to lie here and let your damn circuits cool down. Be a useless lump. Embrace it.”

A weak, watery sound escaped her—a failed attempt at a laugh. It turned into a cough. “Where… is here?”

“My place,” Gojo said. “Shoko’s clinic is downstairs. Too many eyes at the school. This is… quieter.”

His apartment. The memory of the night before the crash surfaced, vivid and unbidden: the sushi containers, the city lights, Nanami’s hands, Gojo’s mouth, the complicated, desperate silence after. Her face flushed with a heat that had nothing to do with panic. Could he see it? Could any of them see it, in her blind, vulnerable state?

As if reading her thoughts, Gojo’s hand lifted from her arm. The loss of contact felt sudden and severe. “You need rest. Actual rest. No getting up to do paperwork, Nanamin.”

“The idea is ludicrous,” Nanami replied. She heard the soft rustle of fabric, perhaps him adjusting his glasses. “I will be outside. Shoko, you have my number.”

“Don’t I ever,” Shoko muttered. Her footsteps receded, followed by Nanami’s. The door swished shut, leaving her alone with Gojo in the gray silence.

The absence of sound was worse than the beeping. The panic, held at bay by their presence and the clinical explanations, began to creep back in at the edges of her mind. The gray felt less like an absence of sight and more like a substance, thick and suffocating.

“Satoru?” His name was a whisper, a lifeline thrown into the void.

“Still here.” His voice came from the same spot. He hadn’t moved. “Not going anywhere.”

“It’s… really dark.” She hated the tremor in her voice.

“Yeah,” he said, no platitudes, no false comfort. Just an acknowledgment. “I bet it is.”

She swallowed, the sound loud in the quiet room. “Are you… wearing the blindfold?”

A pause. “No.”

So he could see her. See the tears drying on her face, the vulnerability, the fear she couldn’t hide. The flush from her earlier memory. Everything. A fresh wave of helplessness washed over her.

“Stop it,” he said, quiet but firm.

“Stop what?”

“Thinking whatever you’re thinking that’s making you look like that. You’re alive. That’s the only metric that matters today.” The mattress shifted slightly as he leaned closer. His voice dropped, losing its final edge of bravado. “You scared the shit out of me, Kura.”

The raw honesty in his words was a greater shock than the blindness. She had no retort, no deflection. She just lay there, floating in the gray, stripped of everything—her sight, her strength, her defenses.

“I’m sorry,” she breathed.

“Don’t be stupid,” he said, but there was no heat in it. “Just get better. The world’s boring without you running yourself into the ground trying to save it.”

She heard him stand up, his movements quiet. “Sleep. I’ll be in the next room. Yell if you need anything. Or just… say my name. I’ll hear you.”

He didn’t wait for a response. His footsteps faded, a door opened and closed softly, and she was truly alone.

The gray closed in. But it was just gray now, not a spinning vortex. His words—“You scared the shit out of me”—echoed in the stillness, a strange anchor in the formless dark. She focused on the memory of the pressure of his hand on her arm, the steady rhythm of his breathing guiding hers. She breathed in. She breathed out.

Somewhere beyond the gray, a vulture was circling. And a predator was waiting. For now, in the silent, sightless calm, she let the fatigue pull her under, clinging to the echo of a voice that never lied about being afraid.
