What will you sacrifice for Satoru Gojo? (Shinjuku arc, Gojo x Reader) PART 3

One.

Two.

Three.

Your eyes opened first. You couldn't see anything, but your heart was beating steadily.

One.

Two.

Three.

You were on the ground, and they were above you. You knew because the construction dust kept drifting down onto your face, forcing you to close your eyes again. Everything was shaking in regular intervals.

Then your hearing came back. Not all at once. The low frequencies first — distant echoes, long and deep, in time with the tremors. Then the mid-range: the acoustic disturbances trailing in the wake of the two sorcerers. The high frequencies came last.

Your peripheral vision returned too. Orange, red, purple, blue, black. The sky was stained with unnatural colors, with cursed energy. Like steam, you thought. And it was. You were soaking in an extraordinary bath of cursed energy. It would have been beautiful to witness, if you weren't part of it.

You smiled. And then the pain hit. That one came all at once. You clenched your teeth. You had dried blood at the corner of your mouth and you tasted the metallic edge of it when your tongue passed over it. Your body was working, yes. You were alive, but you weren't unscathed. You were exhausted from using your technique, and from reverse cursed technique. Your muscles answered when you called them, but the area where the cut had landed still ached, like a phantom limb.

You have to breathe.

You felt one hand. You felt the other. You felt your fingers closed around a piece of concrete with edges that had pressed into your palm — and you were grateful for it, because it was information, it was something solid, it was a way of knowing you were here.

What you'd done was fascinating, actually. Almost paradoxical: using your own technique on your own body, fully conscious that you were receiving an order, should not have worked at all. Conscious minds reject external commands. And yet yours had let it through. Maybe because you were so far outside yourself that you no longer recognized your body as your own — and you no longer had the strength to disagree with yourself. Maybe because you'd come close to an out-of-body experience. If you ever managed to do it again, you thought, you'd become something genuinely dangerous. On the level of Yuta. Of Kenjaku. Of Sukuna and Satoru. But to do that, you'd have to find a way to repeat it on the battlefield.

Above you, the sky kept bleeding color.

Gojo Satoru and Ryomen Sukuna had been at it too long. You watched Satoru flash overhead — looking for you, maybe, or repositioning. He moved with agility, with elegance, with that same dynamism. But also with exhaustion. The careless ease you loved so much wasn't there. He was tired. And in a fight, tired means vulnerable.

Sukuna, for his part, was moving a little more slowly. He'd recovered some mobility in his spine and was carrying himself almost normally now. He was tired too, of course. But he had more battlefield experience than Satoru. And Fushiguro Megumi's young body gave him an edge when it came to RCT.

You hated him.

Not Sukuna. Or — not only Sukuna. You hated Sukuna, and you hated the situation, and you hated yourself for throwing yourself onto the battlefield with no experience and no plan in mind beyond refusing to sit and watch yourself lose the man you loved.

That you could still lose him.

You needed to get back into the fight. Now.

The footage was reaching Mei Mei's screens in fragments.

"What's happening?" Itadori Yuji's voice came out higher than usual. He had his thumb in his mouth and was biting at the skin without realizing. "Kaizuma-san — can anyone see Kaizuma-san?"

"She's alive." Yuta hadn't taken his eyes off the screen. "She's in the collapsed building in the northeast quadrant. I saw her move."

"Move, or just breathe?"

"Mostly breathe."

No one had anything to say to that.

"Well," Choso added, "that's something."

Itadori noticed how flat it had come out. Too flat. Too controlled. He didn't say anything.

Kusakabe scrubbed his face with both hands.

"This is insane. This is absolutely insane. Gojo's running on fumes, Kaizuma's half dead, and the King of Curses is down there putting himself back together like nothing happened—"

"Shut it, Kusakabe," said Choso.

"—and we're up here glued to a screen—"

"I said shut it." This time it was Yuta. He didn't raise his voice. He didn't need to.

Kusakabe shut it.

On the screen, Gojo Satoru fired off a Red.

Satoru's Red always drew the eye. It was beautiful. Like everything that came out of him. From the distance you were at, the shockwave reached you as heat. The sound followed a few thousandths of a second later. Sukuna evaded it.

And answered with a Dismantle.

Satoru took the impact with a hip rotation that turned a killing blow into something merely devastating. He landed twenty meters away, kicking up a cloud of dust on impact. When it cleared, you could see him — composure already restored. Smiling.

Son of a bitch, you thought, and you weren't entirely sure who you meant.

You started moving slowly, listening to your body before risking another contraction. Everything seemed to be working. The pain had partly receded. Fingers first, then arms, then legs.

Good.

Your cursed energy was still circulating. It wasn't draining, because it had nowhere to go. A closed circuit. You moved one leg, then the other.

Above you, meanwhile, Satoru was readying another Hollow Purple. You couldn't see it from where you were, but you could feel the dust drawing upward on one side, and on the other the air being pushed back, repelled. Caught between the two, an almost unbearable pressure was bearing down on your body. And you weren't even up there. You were below — in the eye of the storm, but underneath it.

Sukuna, of course, saw it coming.

What he did next left you and the spectators alike speechless.

He threw himself bodily at Satoru. The whole of him, full force, and he caught Satoru with a punch that broke his stance and sent him reeling backwards. The Hollow Purple destabilized, imploded, and the recoil flung Satoru through the air.

He landed on his feet — but he was bleeding. That, you saw clearly. From his mouth and from his side.

Satoru.

Your head was pounding and his name was the only thing in it. You'd pushed yourself up enough to sit. You were dizzy, and a cold sweat was crawling down your back.

You had to manage to use your technique on yourself if you wanted any chance of saving him. And of saving yourself.

A binding vow is a pact made by jujutsu sorcerers, creating conditions for themselves or agreements with others. Binding vows are considered, by all jujutsu users, one of the essential tenets of the craft. They are, in essence, contracts an individual can form with themselves or with another person. By holding to the rules and restrictions written into those contracts, a user can gain increased power or achieve a specific goal. But breaking a binding vow has consequences.

You would apply your technique to your own body — but you would lose your sight every time you used it on yourself.

"How long has Gojo gone without regenerating?" someone asked, from the other side of the screen room.

"A while," Mei Mei said flatly. "Too long."

"And Kaizuma?"

"She's moving." Yuta hadn't taken his eyes off the screen showing you. "She's using her technique on herself. I think she's… I think she's healing."

"Can she do that?"

"She can now."

Silence.

"Damn," Itadori said quietly. "She's stronger than she looks."

Choso nodded.

To everyone's astonishment, again, something unprecedented happened.

Sukuna deployed his domain for the sixth time. Malevolent Shrine.

You'd never seen anything like it. You'd never had the misfortune of being trapped in the same space as the King of Curses while he had the chance to expand his domain. You were lucky to fall outside it. Inside an expanded domain, the sorcerer's technique strikes with absolute certainty. Inside Sukuna's: Dismantle and Cleave. Invisible. No room to evade. And Mahoraga had already adapted them to Gojo's Infinity.

Satoru responded. Domain Expansion: Unlimited Void.

The two domains collided. For the sixth time in a row. But Satoru's was weak. His brain couldn't hold any more, and Sukuna's was the one that prevailed. Dismantle came at him from every conceivable angle, exploiting the gap left by Infinity. Satoru evaded two. Took the third — it opened a red line from his left flank down to his hip, and this time he didn't cough up blood. The blood just came. Without resistance. Then both domains gave way.

Gojo Satoru got back to his feet. Again. But this time he did it slowly. For the first time in all the years you'd known him: Gojo Satoru was moving too slowly.

And of course he pretended everything was fine, with that wide grin of his.

Idiot.

You'd gotten to your feet. You weren't sure how. Maybe the adrenaline of the fight, maybe your body had decided on its own. The point was that you were standing, and you had cursed energy. And you'd made a binding vow.

Once again, with no plan, you levitated a slab of rubble from a distance and rode it up to the height of the two sorcerers. You looked from one to the other. Satoru was on his feet, his side soaked through, breathing hard. Sukuna was across from him — battered, but visibly in better shape than Satoru.

You had to step in.

Sukuna was stronger than you. That much was clear. Only Gojo Satoru could really go toe to toe with him. Your technique was a mental one. Not physical. You weren't used to close combat. You were strong — just not the way he was. But Sukuna had been fighting for a long time. A very long time. And Fushiguro Megumi's young body, however young, had its limits. Everything does.

You evaded the first Dismantle by a hair.

You felt the cut go past on your right like a gust of cold air. The ground behind you split clean on the diagonal, as though it had always been split.

You threw yourself left. One knee down. You launched off the cursed energy gathered in your legs — not to attack, just to gain height. Three meters. Four. You came down on a twisted steel beam that gave a little under your weight and held just well enough to keep you up.

Sukuna was watching you from below, hands in his pockets.

"You move well. Not bad, for someone who just took a Cleave."

"Thanks," you said, hoarsely.

You'd decided your tactic was going to be confusion. Don't let him think. Keep him off balance until he didn't know whether, what, or where the next attack was coming from.

Sukuna was intelligent in a way Satoru, for all his genius, had never been: with the patience of someone who'd had a thousand years to learn. He didn't improvise. He calculated. He waited. He set the stage he wanted, then carried it out with elegance. That was why he had been the most powerful sorcerer of the Heian era — and quite possibly of the present one.

If you gave him time to think, you died. So you didn't.

You pushed off the beam straight at him, on the diagonal, using the momentum to close the distance before he could reposition. Your technique slipped out like a taut thread from your mind into his. Not a big order. A small one. A single syllable planted in the fabric of his thought before his conscious will could shut you out.

Lose your footing.

Your technique landed and he staggered — which was enough for your fist to reach him.

You caught him in the right side, exactly where his self-inflicted Dismantle had broken his spine before. Not by chance. You'd aimed for the weakest spot. Where the reconstruction was newest.

Sukuna let out a small sound.

"Ngh."

And he hit you back. Bare-knuckled, clean and direct, no cursed energy. You were a fly. An irritating one, but a fly. You went flying until your back slammed into a wall and the air went out of you all at once. You slid down it and landed in a crouch.

You activated RCT immediately, localized, aimed at the point of impact. The rib that had cracked moved back into place with a feeling that wasn't exactly pain, but wasn't anything pleasant either.

In the screen room, Yuta had stood up out of his chair.

"What is she doing?" Itadori was watching the screen with his eyes wide. "Is she taking him on alone?"

"Yes."

"Then why aren't we—?"

"Because," Choso cut in, slowly, "if you go in there and you die, Gojo has one less person at his back, and you've done him no favors at all."

Silence.

"And if she dies?" Itadori asked.

No one answered.

On the screen, Kaizuma (Y/N) evaded another Dismantle by a margin Yuta put at a few centimeters. He closed his eyes. Opened them again.

"She's buying time," he said.

"For what?"

"For Satoru."

The trouble with fighting someone a thousand years old is that he's seen everything you can do before you do it.

Not because he's clairvoyant. Because every movement a human body can perform, every technique a human mind can conceive, Ryomen Sukuna has seen at some point in his existence. And almost certainly trained with it. And against it.

You realized that on your next attempt. Because on your next attack, Sukuna blocked exactly what you were going to do before you'd done it. Not the movement. The intent. He'd read your body before your body knew what it meant to do. You hit empty air, and you fell.

Your RCT was running in parallel, continuous, eating into cursed energy you couldn't really afford to spend. But what mattered now was for Satoru to recover enough to step back into the fight.

Sukuna was studying you.

"It's beautiful, you know," he said. He tilted his head, slowly. "A sorceress throwing herself at the most powerful being in history to save her boyfriend." A pause, almost contemplative. "I had a girl like that once."

You looked at him.

"She died," he concluded.

"Maybe she wasn't as strong as I am," you said through your teeth.

He laughed. A short sound, genuinely amused, which was almost worse than no reaction at all.

"You overestimate yourself, Kaizuma."

"No. You underestimate me." You straightened up. "You're done, Ryomen Sukuna. Just admit it. It's two against one. You needed three to bring him down on his own. Now there's only you. And you're tired. And you're hurt."

He didn't answer right away. He looked at you for a long moment with an expression you'd never seen before. The expression of someone who'd lived a thousand years, fought the best sorcerers history had ever produced, and decided in this exact moment that he'd had enough of you.

"It's been a pleasure, Kaizuma (Y/N)," he said. "I hope you both have better luck in your next life."

You were fast. Very fast.

In less than a thousandth of a second, you went blind.

Dodge.

Your body moved on its own against the incoming Dismantle. Your sight came back almost at once. Sukuna held still for a beat, Fushiguro's eyes fixed on you with something that, in any other being, would have been surprise. Had you actually surprised him? Part of you was glad. You were proud of yourself. But there was no time to lose.

And so you held to a closed economy of cursed energy, channeling it into your own body. Evading. Striking. Accelerating. Sukuna watched you, learned from you, rejected your orders — but you kept trying. You were starting to tire, though. Not from the cursed energy now, from sheer movement. You were spending only the bare minimum to send the commands, but inevitably, given how many of them you were sending, your reserves were ebbing.

Sukuna had shifted strategies. He wasn't underestimating you so much anymore. Now he was bringing cursed energy to bear against you. He didn't deploy his domain, but he was striking with very few restrictions. You weren't giving him time to react. He wasn't giving you time to rest.

But your cursed energy was running out, and you couldn't manage to land another Black Flash.

And then you understood.

The King of Curses was running a war of attrition.

The same one he'd run against Satoru.

You looked up after one of your exchanges — and that was when you saw him.

Satoru. At the perimeter, repositioning. Moving toward the side opposite Sukuna. He'd recovered some strength. Not much. But some.

Your eyes didn't have to meet for you to understand what to do.

Maybe that was part of why you'd always wanted each other. You understood one another. Perfectly. You didn't need to read his mind to know what he was thinking. He was transparent to you, and you to him. Your coordination was immaculate. And right now, that was the only thing that mattered.

Your eyes were still locked on Sukuna's.

Look at me, you ordered him.

He looked. For a second. Less than a second.

And the sky over Shinjuku turned blue.

The pressure wave threw you backwards before you could do anything about it. That's what happens when you stand too close as Gojo Satoru decides he's waited long enough. You rolled through the rubble. The dust took several seconds to settle.

When it did, you got to your feet slowly, your arms shaking, and looked for Satoru.

"(Y/N), run! For God's sake — get out of here!" he shouted in your direction.

"What? No!" you shouted back.

He teleported close to you for an instant. Sukuna had vanished into the dust.

"Please." His eyes were red. A capillary had burst, and a single drop of crimson was sliding down his cheek like an inconvenient detail.

You looked at him properly for the first time since you'd reached the battlefield. He had blood on his lips, on his side, in his eyes. He was wrecked. And it wasn't only Sukuna's doing. Gojo Satoru had burned out his own brain just to stay in the fight. He'd been showing off the whole time even though he knew, and now he really did know, that he wasn't going to win.

In the room, no one was speaking.

Itadori had his arms crossed and his jaw clenched. Choso, beside him, hadn't shifted his expression in several minutes, which spoke for itself. The others couldn't seem to look away from the screens either.

"What are they saying?" Maki asked quietly.

"Nothing good," said Miwa.

"Can you read lips?"

"You don't need to read lips. He's telling her to leave."

Yuta said nothing. His eyes were on the screen showing Satoru, holding there as though he were looking straight through him.

A sudden Dismantle severed his left arm.

The arm hit the ground before he did.

It made the sound of a dull, almost insignificant thud against the rubble. And a second later, Satoru dropped to his knees, slow and badly hurt.

The blood came in spurts.

And you, facing him, made no sound. Not a cry. Not a word. Something inside you leaned forward, toward him, with so much violence that you had to physically stop yourself from going to hold him.

Itadori stood up.

"I'm going."

"You're not." Choso's hand landed firmly on his shoulder. "Sit down."

"He's—"

"Sit down, Yuji."

It was the first time Choso had used his given name. Itadori stayed standing for two more seconds, his eyes still on the screen. Then he sat. Slowly. Without looking away. There was blood on his thumb, where he'd bitten the skin open, and he hadn't noticed.

Miwa had a hand over her mouth. The other was clenched around the hem of her jacket with enough force to whiten her knuckles.

Yuta still wasn't speaking. He wouldn't speak for a long time after this.

You spun toward Sukuna at once, putting yourself between them.

"Get out of here, (Y/N)! GO!" Satoru shouted at your back, in a voice you'd never heard from him. You mattered to him. A great deal. More than you'd let yourself believe.

"I'm not leaving you here!" you shouted back, with the same intensity, and your voice cracked on the last word.

Yuta exhaled slowly through his nose.

"How much does he have left?" Kusakabe asked, very quietly.

Yuta took a moment to answer.

"I don't know," he said. "I've never seen him like this."

No one added anything, because there was nothing to add. Gojo Satoru without reserves was like trying to picture the sun going out: the concept existed, but the mind refused to take it as something real.

Except this time, it was.

"(Y/N), please…" you heard at your back, in a new tone. Pleading. Desperate. Almost hollow. "I can't protect you. Not anymore."

His voice was fading.

"I've given everything. I have nothing left."

You turned to look at him. Slowly. Reluctantly. You didn't want your last memory of him — of the strongest man in the world — to be this. Like prey. Weak. Defenseless.

He was on his knees. The blood had begun to clot around the stump clumsily, as though it hadn't quite responded to his RCT. His white hair was stuck to his forehead with sweat, and blood, and dust, and his eyes — those beautiful eyes, those eyes you'd spent months, years, trying not to look at too closely — were red. Not from crying. Satoru wasn't going to cry in front of you. From bursting.

He tried to smile at you.

He couldn't.

That was the thing that hurt you most all day. More than the Cleave, more than the idea of dying. That Gojo Satoru tried to smile and couldn't.

His voice dropped to a murmur.

"Please," he repeated, "I'm begging you. Get out of here. Save yourself. Run."

You didn't answer — at least not in words. You turned around toward Sukuna, who was stepping out of the dust. He was done playing.

"Dragon Scales—"

You heard the name of the technique and something inside you made the decision before your conscious mind could intervene. Wild. Human. Almost primitive. The same thing that had decided to come to the battlefield in the first place, knowing perfectly well it was a death sentence.

"If you die, I die with you!" you shouted at Satoru.

"Repulsion—"

"I TOLD YOU TO GO!" Gojo roared back, raw, guttural, completely beside himself.

You had never thought of yourself as a special grade sorcerer. On paper, technically yes — but your power wasn't explosive the way Gojo Satoru's was, or Ryomen Sukuna's. You always operated from the back. You ran things from the shadows. You had no greater force amplifying your power, the way Yuta did with Rika. You were just you. (Y/N) Kaizuma. Twenty-eight years old. Until a week ago, your technique had been about telekinesis and reading minds. Suggestions. A little confusion, maybe. Nothing on this scale. So in this battle you were learning a great deal. About fighting. And about yourself.

And what you'd learned was that maybe you were stronger than you'd let yourself believe.

A great deal stronger.

You took your place between Gojo Satoru and Ryomen Sukuna. Between the man you loved and the most dangerous thing that had walked the earth in a thousand years. The dust of Shinjuku settled around you like a shroud, and the only sound you could hear was your own breathing — and, behind you, his. Ragged. Spent. Human.

And Gojo Satoru had almost never sounded human.

Your vision went black.

Domain Expansion.

The four words you hadn't believed yourself capable of saying within the same fight.

"Paired Falling St—"

"Domain Expansion."

A pause. Which lasted no time at all, and felt eternal.

"Divine Intervention."

And the mirrors began to appear across the rooftops for the last time.

[heavenlyfingers]

What will you sacrifice for Satoru Gojo? (Shinjuku arc, Gojo x Reader) PART 2

A series of mirrors spread before you, and around Ryomen Sukuna.

"What the—?" he barely managed to say.

(Y/N) Kaizuma had deployed her Domain!

Divine Intervention.

You looked up. An ethereal light radiated from you toward every reflective surface, multiplying infinitely, blinding your target. The Domain recognized you as its center, its mistress, its only possible law.

In modern sorcery, a Domain Expansion was far more than conquered territory. It was the perfect materialization of one’s innate technique — the sorcerer’s soul projected onto reality until the world itself bent. Within it, every technique struck with absolute certainty. No margin for error. No possibility of evasion. The Domain guaranteed the hit. In your case, it guaranteed an irrevocable command.

He looked at you through Fushiguro Megumi’s eyes — once bright, now completely hollow — and raised an eyebrow with the lazy grace of someone who had gone a thousand years without being truly surprised. Still, he acknowledged it with a hint of cold elegance. "Interesting."

He tried to stop it, of course. He invoked Hollow Wicker Basket. It was the logical response.

The Hollow Wicker Basket was a barrier technique passed down in secret through generations of sorcerers, designed specifically to neutralize the guaranteed-hit effect that every Expanded Domain imposes — much like a Simple Domain. It activated around him like armor woven from structured cursed energy, attempting to negate the rules your Domain was writing into the world.

But it was ineffective. Your Domain was incomplete.

And therein lay the paradox that Sukuna, for all his millennia of experience, had not had time to calculate: Divine Intervention was not a closed Domain. There was no spherical barrier containing the space, no clearly defined inside and outside. There was no shell. You had used the fragments of bricks and collapsed buildings as surfaces for your mirrors, and the sky itself as a reflective plane.

You had done it. For the first time, in real combat. Against Ryomen Sukuna. Against the King of Curses. Fuck, you were actually going to pull it off.

"Ryomen Sukuna, King of Curses…" you said slowly.

Your own voice surprised you. It was clear, steady, and powerful — as though you had been rehearsing this moment your entire life. And in a sense, you had. All those sleepless nights, all those weeks of practice. Or even further back than that. Since the moment you discovered your technique at six years old. A technique you had refined to its absolute limit. Not for persuasion. Not for seduction. Only for this. For this exact moment, when a single command from you could decide the fate of the most powerful sorcerer in history, the strongest of the modern era, and the fate of the world itself.

And this is how it ends, you thought. Satoru lives. Sukuna dies. You walk away unscathed.

"Self-destruct."

Sukuna's eyes — Megumi's eyes — went wide.

It was impossible to disobey you. That was the nature of Divine Intervention: within the Domain, your commands formed the laws of the universe.

"No…" he muttered, and in that single syllable was something extraordinary. Something almost genuine — surprise. "No."

But it was already too late. His other arm began to rise, turning toward his own borrowed body.

And yet. Things rarely go the way one expects.

With a clean, precise cut, Ryomen Sukuna turned Dismantle against himself, severing his own spinal column at the level of the sixth thoracic vertebra. His spinal cord split in two. The neuromotor connection between his brain and his body was severed instantly. His legs stopped functioning, and his arms froze midway, no longer answering to him.

He could not move. He had paralyzed himself to avoid the killing blow.

"What?" Now it was your turn to be left without words.

Had he resisted your mental command? Had he… overpowered you mentally?

Not exactly. He had begun to obey it. But he had been faster. Sukuna was intelligent. Far too intelligent. A thousand years of reputation are not undone lightly. He had used the paralysis as a shield — to avoid paying for his existence. After all, he was the King of Curses and a thousand-year reputation was not so easily discarded.

Your Domain collapsed.

The mirrors shattered inward into nothing, and you fell to your knees on the rooftop of the adjacent building. You were breathing hard, as though you'd just finished an exhausting sprint. Your lungs burned and you struggled to find the right rhythm to get oxygen in. Expanding Divine Intervention was not without cost: every Expanded Domain demanded a sum of cursed energy that the body was slow to forgive, and yours — trained but not limitless — was collecting on that debt now.

Sukuna smiled. He had begun using reverse cursed technique.

Cursed energy, in its most elemental form, is pure destruction: it corrupts, consumes, and undoes. It is entropy. Chaos. But its opposite exists — scarce and extraordinary, mastered by only a handful of sorcerers in all of history — the reverse cursed technique, which takes that same energy and inverts it upon itself, producing something that conventional sorcery refers to, with a certain conceptual unease, as healing. Sukuna wielded it with obscene ease. His tissues were knitting themselves back together at an extraordinary speed, sealing the vertebral fracture from the inside out. He reconstructed his own spinal cord as though the irreparable could simply be undone with enough will and enough cursed energy. Unfortunately, Sukuna had more of both than any reasonable calculation could account for.

"(Y/N)!" You heard Satoru Gojo's voice in the distance.

And then he was beside you, just like that. In an instant. Simple as that. So him.

"Why?!" He looked at you with eyes that, for the first time in all the years you had known him, you recognized as fearful. Satoru Gojo was afraid. For you.

But you couldn't even answer.

Mahoraga descended on him from the left flank. The shikigami gave him no quarter. Satoru was forced to spin on his heel, redirecting every ounce of his focus — and in that exact second in which he stopped looking at you, your certainty about the outcome of this battle began to crack.

"S-Satoru…" you whispered.

But there was no time to waste. You had to get off the building. Now. Without cursed energy. Hurt. A sorcerer without technique is not a sorcerer — they are merely a well-trained body navigating a world it was not built to face without armor. You knew that. You had always known that. But you got to your feet anyway.

For a moment, you wondered what anyone watching from the margins of this battle would think. An idiot doing something idiotic, you thought. Your Domain had been your strongest card — the only reason you belonged on this battlefield. Yet you had played it too early, without a backup plan, against the one being every sorcerer, past or present, feared. And you had still failed. You had underestimated him.

You looked up at the sky. Satoru was running on his last reserves, giving everything he had against an already-adapted Mahoraga, moving with an elegance that under any other circumstances you would have found almost beautiful — but which you now recognized for exactly what it was: the movement of someone spending more than they have, and prolonging the inevitable.

You felt tears rise. You didn't suppress them. What would be the point? You were useless. You had been useless. And now you were nothing but a burden to Satoru, and a weight on his conscience if everything went wrong. You would never be enough.

You stood with difficulty and walked to the edge of the rooftop.

Sukuna had taken shelter beneath the rubble of a collapsed building, healing at a rate faster than you'd thought possible. You could barely make him out from above — a silhouette among dust and fractured concrete, reconstructing himself with patience, unhurried. He knew Satoru was in the same state as him, or worse. And he knew that you were nothing.

You were nothing.

Satoru.

You can't lose.

For him. For Satoru, who was up there rationing the last of his life and cursed energy. The same Satoru who had crossed half of Shinjuku in an instant the moment he saw you fall. The one who had looked at you with fear — real fear — even though he was the Honored One, the man afraid of nothing. The only person who had ever made you feel like you were enough. Like you were his equal.

And so you gathered what courage remained in you — which was not nothing, even when it felt like nothing — and you slid down the face of the building, gripping exposed rebar and jutting slabs of concrete until you dropped into a pile of rubble, broken glass, and dust.

You walked toward where you had last seen Sukuna.

In the sky above, Satoru launched Blue, trying to construct the conditions for a Purple. The process was damaging him. You could see it in the way he moved — in the way he absorbed each hit with a grunt, a sharp exhalation of pain. He was exceeding his limits. It hurt. A lot, you thought. Too much.

"You're a very brave girl," said a voice behind you.

Sukuna. One knee on the ground, barely holding himself upright on the arm that had regained function.

"I'm stronger than you think."

Sukuna drew on what remained of his strength — scarce, but still formidable — and rose to his feet, falling into a fighting stance. Not perfect. But almost. And in him, almost was enough.

And you, drawing on your cursed energy still in recovery, and on a resolve that needed no technique to exist, launched yourself at him. Without an elaborate strategy. Once again. Without a Domain. With no plan beyond the only one that mattered: Satoru Gojo, your boyfriend, was not going to die today. Not while you still stood. Not while your heart was still beating.

And then you landed your first Black Flash.

The impact detonated between your fist and Sukuna’s body in a fraction of a second. The air warped with a pitch-black flash. Those who had experienced Black Flash described the world differently in that instant — sharper, more real, as though pain and power dissolved the veil between a sorcerer and true understanding.

Sukuna said nothing. He simply fixed his eyes on yours with an expression he had not shown anyone in millennia.

And he hit you with a Cleave at point-blank range.

The world tilted.

You felt the cut before you understood it had reached you. That is how pain works when it is severe enough — it arrives late, as though the body needs a few moments to believe what has just happened to it. First came the heat. Then the pressure. And then—

You fell sideways, onto the rubble, the impact of the ground reaching you from very far away, muffled by shock. The sky over Shinjuku opened above you — dirty with dust and residual cursed energy.

Somewhere above, Satoru was still fighting.

Satoru.

You tried to move. You couldn't.

This time you let the tears trace their paths down your cheeks. No sobs. No sound. Just the warm water descending across a face you no longer had the energy to control.

You were going to die.

You weren't afraid — no, that wasn't it. You had accepted this before setting foot on the battlefield. But you had regrets. You regretted dying like this: weak, useless. You had been a fool with too much faith in herself. You also regretted not having told Satoru everything you felt for him. That you knew he wasn't alone. That you were sorry you hadn't been able to save Suguru, either. That you had felt just as lost as he had. That you craved his love. That you wanted to be his — in every sense of the word.

That you loved him.

You took stock of your options.

The dark veil was advancing slowly across your vision, inevitable. You couldn't move. You couldn't scream — attempting it produced a wet, wrong sound that didn't resemble any voice you recognized as yours. And your technique couldn't reach far enough to—

Wait.

The thought arrived without announcement. It was a stupid idea. Probably. A drain of energy that would accelerate the inevitable rather than reverse it, that would add insult to injury, that would—

But your reserves had begun to recover. Slowly. Almost imperceptibly. Enough. Perhaps.

You had to try.

You breathed as much as you could. You had to negotiate with your own body — coaxing your lacerated lungs to accept even the smallest amount of air, ignoring the wet, horrible sound you made with every breath because it didn’t feel like yours.

You were drowning in your own blood.

And you used your cursed technique on yourself.

In truth, it was a logical idea. You had never done it before. You had never had reason to, and you didn't know if it would even work. But there was no other option left. Only this.

Use the reverse cursed technique, you commanded yourself.

Silence.

Reverse cursed technique demands the same as conventional healing: positive cursed energy, the product of multiplying the negative by itself until its nature inverts. Shoko did it with ease. But you were not Shoko. Your technique was not built for this.

But your technique gave orders. And your own mind didn't have the strength to generate them and refuse them at the same time.

Above, Gojo had managed to deal with Mahoraga. You sensed it from the rain of dust that fell across you. But he was still weak — you knew because Satoru Gojo was still gasping, still in pain. He was winning. But at what cost?

You were losing consciousness.

Focus.

You coughed up blood — no, you vomited it: a troubling quantity that forced your body to curl violently against itself in a reflex you didn't control. You gasped for oxygen, your lungs cut in half by Sukuna's Cleave. Lungs, you thought. That's what they are. That's what needs to be repaired. Focus on that. Only that.

Satoru.

He appeared in your mind with perfect clarity: that grin that was always too wide, that stupid habit of mispronouncing your surname, those eyes that sometimes — only sometimes, only when he let his guard down far enough — looked at you with something you didn't know how to name but recognized from somewhere deep inside.

He was the only thing you had.

And you were the only thing he had. However long it had taken both of you to say that out loud. However much the years and the choices and the accumulated foolishness of two people too damaged to ask for what they needed had tried to prove otherwise. It was true regardless.

You could not let Sukuna take that from him.

Not now.

Not now.

And somewhere between the will and the limit, something inside you decided to obey.

Your lungs began to respond. Slowly. Falteringly at first. The air came in. Not much. Not clean. But it came. And then it became easier. Just a little. Enough.

You didn't know how long you had been on the ground.

Time behaves strangely when the body is fighting just to stay alive. It stretches. It contracts. It becomes porous.

Perhaps it had only been seconds since Sukuna hit you with the Cleave. Perhaps minutes. Perhaps the sun had shifted in the sky over Shinjuku and you hadn't noticed because the sky was the same as the ground, the same as the inside of your eyelids — a surface without information, without context, without anything to hold onto.

Perhaps Sukuna had already lost.

Perhaps it was Satoru lying dead somewhere in the rubble above.

Your mind, in that state, had no capacity to process what that would mean. It had capacity for almost nothing.

And so you simply existed.

Alive.

(Y/N). You're alive.

Mahito my beloved.

[heavenlyfingers]

What will you sacrifice for Satoru Gojo? (Shinjuku arc, Gojo x Reader) PART 1

Losing people has never been a problem for you.

Or rather, it shouldn't be. You have never felt loved by anyone, and your attitude has been the same— a fair exchange, you'd always told yourself. But the mere thought of never seeing Satoru again twisted your stomach and painted your heart a dull, heavy gray. 

He doesn't know if he's going to win.

You had watched him for years. He always carried his shoulders straight, head tilted back with that arrogant, confident smile that convinced everyone he had the world under control. That him alone was everyone's savior.

But he didn’t have anything under control.

That afternoon, you had seen it in his eyes. Those usually bright, mischievous eyes were different.

Satoru.

His name came without permission, without the careful distance you had tried to maintain these last few months. Without the mental detachment you had spent years building. It slipped in on its own, the way it always did when you let your guard down. Like a prayer. Like a hymn. As if Satoru were your religion.

The others had gathered around Mei Mei’s screens. Satoru had launched the first strike, catching Sukuna off guard. But Sukuna was Sukuna. That advantage would likely be the first and last he ever got in this fight.

On the screens, he looked happy. You knew it was genuine. He had never had the chance to fight someone on his level before. Not even you, with your technique capable of bypassing his Infinity, could face him in a real confrontation. Neither could his best friend. Nor his strongest student. Some things couldn’t be measured by special grades—and Sukuna was one of them. Something older. Something that had existed long before the system that tried to name and classify and pretend it could contain them. And Satoru Gojo, the only other.

You lifted your gaze.

Yuta Okkotsu was glued to the screen, arms crossed, jaw tight. He was afraid too. He noticed you watching him—he had always been too perceptive for his age. He turned slightly and gave you a bitter smile before looking back at the battle.

You didn't smile back. You couldn't even manage that.

Your eyes returned to the screen. They had just blown up an entire building. Dust filled the frame for a second, then settled. He was enjoying it like a child on Christmas morning, with that lightness you had always found both admirable and infuriating. 

Oh, Satoru.

“…so if that guaranteed-hit effect is inside the barrier itself, it becomes a battle of domains, right?” Miwa said from across the room.

You glanced at her, then at the others. They were calmly explaining Sukuna’s Domain Expansion. Their voices sounded muffled, as if coming from the other side of thick glass. Like the whole room existed in another plane and you hadn’t been able to tune into it this entire time. Weren’t they going to do anything if he lost?

Fuck.

You didn't move.

It was entirely possible he would lose.

You closed your eyes. Opened them again. They were wet. You looked at the screens, then the window, then the floor. Your stomach remained a tight knot of nerves, heavy and acidic. Satoru had accepted the possibility of losing—that was why he had said goodbye to you the way he did. That was why he hadn’t bothered with a condom the night before, and why he had made you feel things no one else ever had in just a few hours.

In the hallway, right before he disappeared from sight, he had lifted two fingers to his eyes and then pointed at you, saying something he couldn’t put into words any other way.

Don't do anything stupid.

Or maybe simply: See you later. Which scared you more than if he had done nothing at all.

Satoru had always been like the sun to you. Lethal if you got too close, yet hard to ignore from any distance. For twelve years you had calculated the exact orbit needed not to burn, measuring the space with a precision that had cost you more than you would ever admit out loud.

But now you saw him on the screen, small against the scale of the destruction around him, and all your careful calculations meant nothing. So you allowed one forbidden thought to cross your mind for the briefest moment:

You loved him.

“(Y/N).”

Yuta’s voice was low beside you.

You didn’t answer right away. Your eyes were fixed on the screen, on the exact moment Gojo Satoru lifted his head toward Sukuna. There was something in his posture that shouldn’t have been there. Something you recognized and wished you didn’t.

Almost amusement.

You idiot.

You didn’t know if it was an insult or a caress.

"I'm fine," you said at last.

Yuta didn’t reply. He turned his eyes back to the screen. So did you. Neither of you said what both of you already knew: the understanding between you was absolute. You had both felt the same thing for two different people, and that bound you together almost like soulmates. That… and what you had whispered to him weeks ago—what you would do if the moment came. What you would do. What you had already decided.

You glanced at him one last time.

He wasn’t smiling either.

Some things, once named, became real. Especially for someone like you. That was why neither of you said anything. That was why you didn’t want to think about it now either, with your eyes glued to the screen and your heart stained that gray you still didn’t have a better name for.

He knew he might lose.

And you were terrified to believe it.

Domain Expansion.

For a few seconds, you saw nothing. But then—

“A draw,” a voice said from the back.

“No way!” Kusakabe shouted.

“That can’t be!” Mei Mei added.

Everyone knew that inside the domain, the effects canceled each other out.

The problem was that Sukuna’s domain was larger than Gojo’s.

And the barriers of these territories…

“…are weak to attacks from the outside,” Itadori finished.

Then a slash from Sukuna tore straight through Satoru’s Infinity.

It sliced across his neck.

Your blood ran cold.

But just as you were about to react, Satoru began using Reverse Cursed Technique to heal himself.

You allowed yourself to breathe again.

Almost. It had been too close.

Still, as long as Satoru remained inside Sukuna’s domain, the cuts would keep coming, and he wouldn’t be able to use his technique properly for a while. His best chance had been constantly healing with Reverse Cursed Technique. You silently thanked the heavens that he was so efficient and had such immense cursed energy. Anyone else in this room would have died from the first strike.

Satoru…

The fight continued. Gojo Satoru deployed a Simple Domain to temporarily stop the attacks, but he stopped using Reverse Cursed Technique to heal himself. That allowed Sukuna to land several blows that scarred his beautiful face.

He’s desecrating my sanctuary.

You started sweating. A cold sweat that clung to your clothes. It began in your armpits and thighs, then spread to the back of your neck, your feet, and finally your forehead. You didn’t notice until a drop fell into your eye and you had to wipe it away with your sleeve. Your attention remained completely fixed on the screen.

Then Gojo unleashed a Red. He expanded his domain once more. And lost it again.

Satoru.

He cast a third domain.

Your eyes scanned the screens with the sharp focus of a predator ready to pounce. Satoru was frying his own brain with so many domain expansions, yet he still managed to keep that devastatingly attractive smile—the one that always made your heart melt. This time, though, it only made your heart clench and beat in strange, painful ways.

You leaned closer to the screen. Not because it helped you see better, but because being closer to his image, to him, made you feel somehow more capable of helping—even though you knew you couldn’t. No one could.

The domain shattered. Gojo was testing new ideas, things you had never seen anyone do before. He wasn’t following any particular strategy. He was simply…

“He’s showing off against Sukuna,” you said out loud.

The others turned toward you. They agreed.

“And Sukuna isn’t even going all out. Not even close,” Maki added.

You nodded.

He knew he could lose.

Satoru was intelligent. But Sukuna was something else entirely. He was the King of Curses. The strongest sorcerer in history. Everything Satoru Gojo knew, Sukuna had known hundreds of years ago. You felt tears beginning to fill your eyes once again. You hadn’t wanted to face the possibility that the man you loved could lose, but now it felt much closer than you had ever imagined.

And then they unleashed another domain expansion.

And another.

Blood was dripping from Satoru’s nose. This wasn’t from Sukuna anymore—it was from himself. His brain was fried. You didn’t understand why he wouldn’t stop trying or call for help. Even if some of you died in the attempt, you could still help him, couldn’t you?

But this time, he had the upper hand. Sukuna had taken a millisecond too long to expand his domain, so Satoru struck him and managed to land a hit—

Mahoraga appeared on the battlefield. And it had already adapted to Gojo’s Unlimited Void.

You gasped, your breath catching in your throat once again.

Yuta must have heard you, because he stood up and moved to your side. You grabbed his hand with all your strength, eyes still glued to the screen. He squeezed back. He glanced at you sideways. Your eyes took in everything—every movement, every flash, every second—as if you were searching for something specific within the chaos.

Yuta didn’t say a word. He simply held your hand firmly, reminding you that you weren’t alone. But both of you knew that in this situation, you were completely and hopelessly alone.

Itadori noticed. He didn’t say anything either, but he came to stand beside you, a little further back, making it clear he wanted to offer support too. Choso followed his brother. Maybe he had grown fond of you these past few weeks. Or maybe he was simply following Itadori. You barely registered either of them.

Mahoraga.

On the screen, both tried to cast another domain expansion. Neither succeeded. Blood poured from orifices that shouldn’t be bleeding. Now they were simply fighting. You kept watching. But now you were noticing things you shouldn’t notice. You were trembling. And you shouldn’t be. You trembled, you sweated, your breathing was ragged, and your heart was pounding everywhere. Satoru seemed to have lost his sanity, yet he smiled, fought, dodged, and showed off—for him, for all of you, for you.

But there were only three turns left before Mahoraga fully adapted to Infinity.

Three.

You were deathly pale. Too pale. You had completely cut off the circulation in Yuta’s hand. He turned and looked at you. You didn’t want to meet his eyes. You didn’t want this to become real.

“Sa… Satoru…” you muttered through clenched teeth.

Seeing you like this, he pulled away and gently took your face between his hands.

“(Y/N), look at me. Please. He still has a chance. He’ll kill Sukuna before it fully adapts.”

But both of you knew that wasn’t true.

“We can do something,” you said. “There has to be something we can—”

You cut yourself off.

In the background, Satoru—or what was left of him—continued fighting against the King of Curses, Ryomen Sukuna.

You stopped clenching your teeth and your expression softened. But it wasn’t calm. It was something far more useful. Yuta noticed and let go of you.

“(Y/N)? What…?”

Then you turned toward Ui Ui.

Yuta’s expression changed, but by the time he could react, you were already speaking.

“Your technique… it’s teleportation, right?”

The boy nodded slowly.

Satoru.

“Yes. Why?”

His eyes darted toward his sister. Mei Mei barely moved, only tilting her head slightly.

“No,” she said firmly, without taking her eyes off the screen. “Don’t even think about suggesting it.”

No one else spoke until Itadori looked at you, reading your face. Despite his young age and limited experience, he understood exactly where your question was heading.

“Kaizuma-san… No.”

Yuta grabed your hand again and squeezed it tightly.

“We agreed you would only observe,” he murmured, just for you. “Until we were sure. That was the deal.”

On the screen, Gojo tried to fire a Red, but Sukuna’s amplification countered it.

Another turn.

Choso watched you from across the room with dark, worried eyes. If anyone understood what it meant to lose the people you cared about most, it was him. He should have supported you. But he didn’t.

“If you go in there,” he said quietly, “you’ll die.” A short pause. “And he’ll know. He’ll feel it.” Another pause. “What do you think that would do to him in the middle of the fight?”

You pulled your hand free from Yuta’s. The paleness had left your face. In its place was something worse. Something dangerous.

“It’s going to adapt. Fuck. Take me there. Now.”

“No.” Yuta stepped in front of you before Ui Ui could move. “No, (Y/N). Don’t you dare.”

Ui Ui still looked unsure what to do. He glanced at his sister again, who warned him with a single word.

“Ui Ui.”

Itadori stood up instinctively, positioning himself between you and the door.

“Kaizuma-san, listen to me. If you go in there right now with Mahoraga on the field—”

“I know,” you gasped. “I know, but if Mahoraga adapts to Infinity—”

“Gojo knows that too,” Yuta interrupted, placing his hands on your shoulders and forcing you to look at him. He brought your face close to his. He was losing his composure as well. “He knows, (Y/N). He’s calculating. He’s—”

“I have to go, Yuta. Let me go.”

The rest of the room had shifted their attention to you. You felt the weight of their stares, but you didn’t care. Nothing mattered except the screen and what would happen in the next ten seconds.

“Stop.” It wasn’t a plea—it was an order. “Stop, (Y/N).”

“LET GO—”

“Stop!” Yuta explained with all the calm he could muster. “If you teleport in there, Sukuna will see you. He’ll use you. Or worse—he’ll try to get rid of you. And Gojo… Gojo will see you at the most critical moment of his life and…”

He stopped and swallowed hard.

“He’ll watch you die, (Y/N). That’s what will happen. He’ll see you die right in front of him and he’ll lose. Then everything will have been for nothing.”

The final turn. Satoru.

You yanked yourself free from Yuta with a sharp motion. You walked toward the boy with tunnel vision. You had to go. You had to get in there and help him. You didn’t care if you died. You didn’t care if the others died. In that moment, the only option that existed for you was to go. It was the only thing you had left.

You grabbed Ui Ui and shook him, tears filling your eyes.

“Do it now!”

His eyes widened in fear. He looked at Mei Mei, who stood up and crossed the room in three quick, silent strides. She aggressively pulled you away from her brother.

“Are you crazy…?”

Yes.

You were.

In love—especially when you’re about to lose someone precious—there is a razor-thin line between concern for the person you love and pure madness. And you had just crossed it. Because what you felt wasn’t just love. It was devotion. Like Rika and Yuta. Like a devotee to their god. It was blind and unquestionable. Nothing else mattered.

Not even your own life.

Especially not your own life.

So you did the only thing you could do: you gave her a mental command.

Ui Ui looked at you, bewildered, but it was already too late. His sister spoke for you.

“You have permission. Take her. But come back immediately.”

Ui Ui, unaware of what you had just done, scratched the back of his neck and looked at you. You took a step forward, inviting him to cover you with his blanket. In the background, the others argued about whether they should go help too. Their voices reached you muffled, more distant than before. You knew you were right. This was the best idea. Even Yuta seemed to have changed his mind. But in the end, they decided not to go. To them, Satoru was still the solution—the weapon. The one who could defeat Sukuna at his strongest.

But they weren’t counting on the power of love.

Satoru.

Ui Ui covered you with his blanket.

You appeared in Shinjuku.

Not at the epicenter of the fight, but a little further away from the two of them. The air was thick with dust and cursed energy overwhelmed your senses. You knew Satoru would notice you as soon as possible, so you activated your technique to camouflage yourself. You became invisible. Undetectable. Just like Maki Zen’in. Just like Toji Fushiguro.

FLASH

The purple flash missed you by centimeters.

Satoru?

You ran. Adrenaline surged through your veins like heroin—hot, powerful. Everything except your goal faded away. You ignored the rocky, destroyed ground beneath your feet.

You ignored the burning pain in your feet. You ignored the smoke scorching your lungs. You ignored the colossal shikigami looming in the distance. None of it mattered. Absolutely nothing mattered.

You ran toward him.

You ran.

And ran.

And kept running.

You dropped your camouflage.

And the moment you saw Sukuna, the moment you saw Satoru, the moment you realized with terrifying certainty what was about to happen…

“Domain Expansion: Divine Intervention.”

OBIDIENCE

What (Y/N) possesses is not, strictly speaking, a cursed technique in the conventional sense.

Most techniques are extensions of the body—projections of cursed energy thrust outward into the world, into opponents, into constructs born of will made manifest. At their core, they all obey the same ancient principle: force meeting force. The stronger current prevails.

Cursed energy, at its most fundamental level, is born from the human mind—negative emotion, accumulated experience, the weight of consciousness pressing against the boundary of the flesh. What she has learned, what her cursed energy has always understood instinctively, is that this process can be reversed. She reaches inward, into the very origin point of another’s cursed energy. What she touches is the mind.

A command planted there, before the host’s own will has fully assembled itself, cannot easily be recognized as foreign. It arrives cloaked in the texture of their own thoughts. She sets it at the root, where it is nearly indistinguishable from their own intention.

The comparison to Inumaki Toge is understandable, yet ultimately incomplete. She carries Inumaki blood, though it is distant. What was passed down through the generations was not the cursed speech itself, but the inclination beneath it. In the Inumaki clan, that understanding became language—commands carried on sound, entering through the ears and compelling both resolve and body from the outside in. An imposition. A skilled sorcerer can intercept it at the point of entry. There is a seam because the attack has direction.

What Kaizuma (Y/N) inherited from that same root diverged entirely. The inclination never became language. She does not pronounce a command. There is no external word to intercept and no audible intrusion to recognize.

Her Innate Domain—what she calls Divine Intervention—is the perfection of this principle, and also its limit made visible. Within that bounded space of infinite reflection, the distance between mind and soul collapses. The target sees nothing but a divine figure. Her. And in that religious ecstasy, her command becomes something closer to law than instruction: one action, absolute and total, performed exactly as she wills it. A single, perfect execution. 

Whether that constitutes a lethal domain is the wrong question. The domain itself does not kill. It does not incapacitate through brute force like Unlimited Void or strip weapons away like Deadly Sentencing. What it does is place the decision entirely in her hands. 

Like all completed domains, it operates through a sure-hit effect. Sorcerers trained in anti-domain techniques—Simple Domain, Hollow Wicker Basket, Falling Blossom Emotion—can neutralize the domain’s reach. They would survive the expansion itself.

In this sense, she is perhaps the most dangerous category of sorcerer that exists.
