Satoru Gojo

Satoru Gojo learned early that love, when left unattended, rots into something sharper.

He didn’t have the words for it as a child. Only the sensation: the hollow echo of voices speaking about him instead of to him, the way servants’ hands trembled when adjusting his clothes, the way elders smiled like men standing too close to a bomb. He understood instinctively that he was not meant to be held, only revered, and that reverence was a poor substitute for warmth.

Satoru learned the shape of loneliness before he learned language.

hands that hovered instead of touched, voices that softened into reverence, eyes that watched him like he might explode if handled incorrectly. He was never told outright that he was dangerous, only treated as if he were something that needed to be contained carefully, like glass under pressure. The Gojo clan compound was pristine and enormous, its halls echoing with footsteps that never quite reached him. Even as a child, he could feel the invisible boundary drawn around his existence. No one scolded him. No one played with him either.

So when another child appeared one afternoon in the garden—small, plainly dressed, standing stiffly with the posture of someone who had been instructed very carefully how not to misbehave—Satoru noticed immediately. Not because they were important, but because they weren’t afraid. They didn’t bow low enough. Didn’t avert their eyes quickly enough. Didn’t flinch when he approached too close, peering into their face with unfiltered curiosity.

They didn’t come with instructions. No script. No reverence. They didn’t bow deeply or avert their eyes. They just stood there in the garden, blinking at him like they weren’t quite sure what kind of creature he was supposed to be.

“Who’re you?” he asked bluntly in that squeaky kid voice. They hesitated. Glanced toward the adults lingering at the edges of the garden like decorative statues. Then gave their name quietly.

Satoru stared—He stepped closer, close enough that the attendants stiffened, ready to intervene. He tilted his head, peering at them through white lashes, Eyes humming faintly as they tried—and failed—to assign danger.

“Hey,” he said, blunt and unceremonious. “You’re my friend now, right?”

It wasn’t a question—Later, when he was older, he would recognize that moment as the first time something chose him instead of the other way around. Or maybe he chose it. The distinction blurred over time.

The adults called it a transaction. A low-ranking clan offering up a child to serve as a distraction, a balm, a preventative measure against the tantrums of the strongest sorcerer alive. They framed it as kindness. Opportunity. Mutual benefit.

Satoru framed it as ownership. He learned quickly that if he cried hard enough, they stayed longer. If he clung, no one dared pry his fingers loose. If he smiled and said he’d behave—as long as they were there—the elders agreed with tight jaws and tighter smiles.

He didn’t just want them nearby. He wanted them orbiting him. Sitting beside him during lessons. Eating when he ate. Sleeping within shouting distance. The idea of them leaving became unbearable long before he had the language to express it, so he expressed it the only way he knew how: possession disguised as need.

If he had nightmares, they were called in to soothe him—If he was bored, they were summoned.

If he was angry, they were placed gently between him and whatever had upset him, like a grounding wire.

And if anyone else tried to take their attention—another child, a servant, an instructor—Satoru felt something dark and electric coil in his chest.—That thing learned to smile.

At Jujutsu High, the world expanded, and Satoru pretended that meant freedom. Teenage years softened the edges of his obsession, or at least disguised them better. There were friends now: Suguru, calm and principled; Shoko, sharp-tongued and exhausted; Nanami, perpetually irritated by everyone. Missions that made him feel invincible. Power that bloomed until even the elders flinched.

But even surrounded by noise, laughter, battle, and blood, his attention always threaded back to one constant. Them.

He hovered unconsciously, positioning himself half a step closer to danger, intercepting blows, redirecting curses before they came close. He justified it easily—he was stronger, faster, better equipped. Why wouldn’t he take the lead?

When they were injured, even slightly, something feral rose in him. When they laughed with someone else, he felt an irrational irritation coil under his skin. When they talked about the future—about missions, promotions, independence—he smiled and nodded and quietly catalogued every variable that could be removed to make those futures unnecessary.

Suguru noticed more than he let on. “You ever think about letting them breathe?” Suguru asked once, voice light but eyes sharp, as they watched the sun dip below the campus roofs.

Satoru scoffed. “I let them breathe all the time.”

“That’s not what I mean.” Suguru murmured, his eyes locked onto Satoru.

The words hung there, unanswered.

Then Riko died.

The news didn’t haunt Satoru nearly as much as the silence afterward. The way everything stopped. The way the world continued despite something so precious being erased without ceremony. He learned, in that moment, that strength did not mean control. That infinity could still be pierced by inevitability.

Suguru broke loudly after that. He raged against the system, against humanity, against the endless cycle of sacrifice and suffering. Satoru watched him go with a numbness that frightened even himself. When Suguru died years later—really died—Satoru didn’t scream—He didn’t cry. He just felt the universe shrink.

When Suguru died, it felt like confirmation. After that, Satoru stopped pretending the world was salvageable.

And suddenly, the idea of losing another person like that became impossible to tolerate.

He threw himself into teaching, into missions, into being everywhere at once. He laughed louder, smiled brighter, acted even more obnoxious. People mistook it for resilience.

They didn’t see the way his gaze lingered on them longer each day. Didn’t hear the calculations forming behind his jokes. He started noticing patterns. How often sorcerers died young. How even talented ones were ground down by missions and bureaucracy. How close calls stacked up until luck ran out.

He imagined their name on a report one day. He began to see death everywhere. In mission reports. In casual injuries. In the way curses adapted, grew smarter, meaner. The Six Eyes fed him probabilities, outcomes, timelines that all ended the same way for people who stayed in the field long enough. And something inside him snapped—not violently, but quietly.

Satoru never thought of it as poisoning. That word implied malice. Carelessness. A desire to harm—This was precision.

Every morning followed the same rhythm. He woke before them—always before—long before the house stirred, long before they could hear the soft hum of the barriers shifting as he adjusted them. He moved through the kitchen silently, familiar with every creak of the floorboards, every shadow the dawn cast through reinforced glass. He prepared everything himself.

Tea steeped just long enough to be comforting. Soup simmered low and slow, seasoned carefully, nutritionally balanced, tailored to what he told himself their body needed that day. Medication lined up neatly on the counter—some prescribed, some… supplemental. Nothing dramatic. Nothing immediate.

Always diluted. Always measured—Always his hand.

The addition was so small it vanished the moment it touched liquid. Colorless. Tasteless. Something that disrupted without destroying, weakened without killing. Something that blurred the body’s signals just enough that no alarm bells rang loudly enough to demand action.

He watched it dissolve every time. And every time, he felt that familiar tightening in his chest—not guilt, not fear, but something closer to resolve—This is necessary.

When he brought the cup to their lips, his expression never changed. Still warm. Still teasing. Still so convincingly kind that even the Six Eyes, turned inward, couldn’t accuse him of cruelty.

“Careful,” he said softly. “It’s hot.” They trusted him, That trust made everything easier.

The sickness never announced itself as violence. That was important to Satoru.

Violence was messy. Obvious. Violence left room for resistance, for anger, for someone to say this is wrong. He didn’t want that. He wanted inevitability. Something slow enough that even the Six Eyes, turned inward, could justify it as chance.

So the illness wore the mask of frailty. It started with exhaustion that clung no matter how much rest they got. A heaviness in the limbs, like gravity had quietly increased when no one was looking. Their cursed energy output dipped—not catastrophically, just enough to be concerning. Enough to make missions harder. Enough to make recovery stretch uncomfortably long. Satoru noticed everything.

He noticed the way their hands trembled when lifting a cup. The way their breathing hitched after walking too far. The way they hesitated before agreeing to assignments, uncertainty creeping into places where confidence used to live.

He catalogued symptoms like love letters. “You’re pushing yourself too hard,” he said gently, every time. Always gently. “You’ve always been like this—too kind to your own body.”

When fevers came, they came softly. Low-grade. Persistent. The kind doctors waved off with tired shrugs and stress-laden diagnoses. Shoko frowned more often than she spoke, eyes sharp as she reviewed test after test that returned frustratingly inconclusive.

“It’s weird,” she muttered once, cigarette forgotten between her fingers. “Your vitals don’t line up with how bad you look.” Satoru smiled, easy and bright. “Guess that’s just how they are.” He said it often enough that it became truth—The sickness made them doubt themselves before it weakened them completely. That was the point.

On bad days, Satoru became indispensable. He guided them back to bed when dizziness stole their balance, hands firm but careful, like handling something precious and breakable. He brought water already chilled to the right temperature. Food prepared specifically to be easy to digest. Medicine—approved, reasonable, measured—administered with the air of someone who knew exactly what he was doing. Which, of course, he did.

“Don’t apologize,” he said whenever they did, voice laced with soft reproach. “You didn’t choose this. Honestly, it’s my fault for letting you overdo it.”

Letting.

That word slipped in everywhere. When they protested missing missions, he reframed it as responsibility. When they worried about burdening him, he laughed it off, loud and exaggerated, as if the idea were absurd.

“Taking care of you isn’t a chore,” he said, brushing damp hair from their forehead while the fever made their thoughts fuzzy. “It’s literally the easiest thing in the world.”

And maybe it was.

The more the illness progressed, the smaller their world became. The house—his house—was arranged perfectly for recovery. No sharp edges. No unnecessary stairs. Wards tuned not just to repel curses, but to contain. Outside noise dulled to a distant echo. Days blurred together, marked by meals, medication, sleep, and Satoru’s constant presence.

He talked constantly—About trivial things. About old memories. About how dangerous the jujutsu world had become lately, how many sorcerers had died on missions they shouldn’t have been sent on. About how unfair it all was.

“You’re lucky,” he said one evening, tone light, almost teasing, as he adjusted blankets around their shoulders. “You get to skip all that.”

Lucky.

If they questioned it—if some small, stubborn part of them tried to articulate that they hadn’t always been like this, that something felt wrong—he never shut them down outright.

That would be suspicious.

Instead, he validated, redirected, reframed. “You’ve been through a lot,” he said sympathetically. “Trauma messes with the body. You remember Riko, right? Suguru? It’s probably all just catching up to you.” He let the silence do the rest.

Guilt was a powerful suppressant—The sickness worsened in quiet increments. Muscles atrophied from disuse. Standing became an effort. Walking any distance left them breathless. On particularly bad days, even sitting upright for too long brought on nausea and trembling.

Satoru, of course—adjusted seamlessly.

He stopped encouraging movement. Stopped mentioning recovery timelines. Started using language like maintenance instead of healing.

“This is just how things are for now,” he said calmly. ”We adapt.”

He began staying closer. Sleeping in the same room “just in case.” Keeping a hand on their wrist while they slept, fingers brushing pulse points with unconscious possessiveness. The barriers tightened without announcement, subtle enough that only someone like him would notice the shift.

No visitors without his approval.

No doctors without his presence.

No conversations he couldn’t hear.

Sometimes, in the quiet hours, when the sickness left them too weak to hide their thoughts behind politeness, they cried. Satoru handled that worst of all. He wiped tears with practiced tenderness, voice low and soothing. “Hey. Hey. Don’t do that to yourself.”

do what? they might have asked.

“Thinking you’re broken,” he said softly. “You’re just… different now. That’s okay.”

Different meant staying, Different meant depending, Different meant alive.

On the rare occasions doubt crept into his own mind—when he caught his reflection in dark windows and thought, distantly, this is too much—he crushed it with logic so airtight it felt righteous.

If the sickness kept them out of danger, it was worth it—If dependence meant survival, it was kind. If love required control, then control was love. He was the strongest. He knew better than anyone how the world worked.

And the world, left unchecked, would kill them. So he stayed at their side, endlessly patient, endlessly attentive, watching the sickness bloom exactly as intended—not as a disease, but as a solution.

One night, as he helped them drink slowly from a glass, his voice dropped into something softer, almost reverent.

“You don’t need anyone else,” he murmured. “I’ve got you. I always will.” His smile never wavered.
