JUJUTSU KAISEN MASTERLIST
At first, he’s irritated. Not at you but at the inconvenience of the circumstances. “Your body is weak. How irritating.” And yet, of course, he doesn’t leave.
He’ll lurk nearby, pretending disinterest, but the moment you shift in pain, his eyes flick toward you instantly. He notices everything.
He won’t fuss or coddle. Instead, expect his hand to press against your abdomen, cursed energy flowing subtly, easing the cramps effortlessly. “Stop writhing. It’s annoying,” Ryomen mutters, though his hand doesn’t move.
He mocks you endlessly. “Is this really enough to bring you down?” “How pathetic your body is.” His tone is cruelly teasing.
Secretly (and he’d never admit it), there’s something about your vulnerability that makes him even more possessive of you. You’re his. Your pain, your every shiver of discomfort - all of your weaknesses are his to exploit. He will brand you so no one else will ever touch you again.
His Blood Manipulation lets him sense subtle changes in your body’s chemistry - he can literally smell when your period is about to start. The second he notices, his protective instincts kick in before the cramps even hit.
“Does it hurt? Where? How bad? Tell me everything, Y/N,” he demands softly, needing details so he can act precisely. He’s very methodical.
Choso subtly manipulates his blood while rubbing little circles over your tummy, warming it just enough so his palm acts like a heating pad on your stomach. The heat, his heat, radiates soothingly. He watches your reaction like it’s the most important thing in the world, instantly adjusting if it’s too much or too little.
If you’re tearful or frustrated, Choso doesn’t question it. He just pulls you into his arms, holding you like you might crumble otherwise.
Even though it’s definitely not the right time, Choso might suggest a quickie. He’s straightforward about it: he doesn’t mind the blood; he claims it’s not gross at all; he insists there’s no better stress relief for cramps than sex.
He loves being physical with you - hugs, nuzzles, keeping you in his arms with his chin resting in the crook of your neck - these are his ways of showing that he cares for you.
The moment he realizes what’s happening, he’s hooked. He’s fascinated. Completely, utterly fascinated.
He crouches at the edge of the bed, chin in his palm, staring at you with wide, delighted eyes. “Wait, your body willingly puts itself through this every single month?” To him, it’s less inconvenience and more a fascinating ritual of flesh, something so uniquely human that he can’t stop poking at the idea.
His first instinct is, of course, deeply alarming. A grin stretches across his face as his fingers twitch with temptation. “I could fix it in one touch, you know.” He says it so casually, like reshaping your insides is the most obvious solution in the world. The firm no you give him only makes him laugh, shoulders shaking with amusement. “Humans are so attached to their suffering. That’s adorable.”
Despite his chaotic nature, he ends up helping in his own weird way: he reshapes part of his arm into the perfect heating pad, molded exactly to the curve of your stomach.
What makes it strange is how observant he becomes. Mahito memorizes every reaction: what drink makes you feel less nauseous, how much pressure helps, whether warmth works better on your stomach or lower back. Once he learns the pattern, he repeats it with eerie precision, almost proud of how quickly he’s solved you.
Might rest his head on your lap while you lie there, absentmindedly tracing patterns over your tummy. “Humans are so fragile but you’re interesting like this!”
With Suguru, it starts before the first cramp even hits. He catches the faint shifts in your mood, the way your shoulders tense, the subtle fatigue in your eyes. By the time you realize what’s coming, your favorite tea is already steeping, and a blanket has somehow found its way over the couch.
He sits beside you, fingers brushing slowly through your hair, smoothing it away from your face in repetitive motions that almost lull you to sleep. His voice drops into that velvet calm he uses when he wants someone to listen. “Breathe. Let the tension go.”
When the cramps worsen, he wordlessly shifts closer and opens his arm for you. The moment you lean into him, he secures you there, one arm around your waist, his other hand resting low on your stomach with slow circles, almost meditative.
Geto’s affection is subtle: a soft kiss to your temple when you wince; his lips brushing your hairline while tears of pain roll down your flushed cheeks. The tenderness feels almost disarming because it comes from someone so composed, making it all the more powerful.
Suguru absolutely keeps track, though you may never realize it at first. He remembers the dates, the symptoms, even the little preferences you mention offhandedly.
The moment Nanami notices the faint tension in your shoulders, the way your hand lingers over your abdomen, or the slight sharpness in your breathing, he mentally restructures the day. Meetings? Delayed. Errands? Handled by him. Anything remotely stressful is quietly removed from your path before it can even reach you.
Nanami is the type to remember what eased your pain three months ago. The exact tea that helped bloating, the pillow angle that supported your back best, the pressure point that made your cramps less sharp. He stores these things away with the same efficiency he gives to exorcising curses, and somehow that makes it feel even more intimate.
Nanami rarely lets emotion show, which is why it’s so striking when his voice softens. He sets aside whatever he was doing and moves closer, his hand resting at the small of your back or over yours in a grounding, steady way. “Tell me immediately if it worsens.”
He will absolutely keep track of the time between your medication doses, hydration, and meals with that almost inhuman sense of precision. You don’t even need to look at the clock. The moment it’s time, he’s already there with exactly what you need. There’s something oddly comforting about the fact that, in Nanami’s hands, even your discomfort feels managed.
The most Nanami thing of all: he sees rest as a responsibility, not a luxury. If you try to push through the pain, he gives you that calm, unimpressed look over his glasses and simply says, “Your body is not a machine. Stop treating it like one.”
Kento will absolutely read to you - a book or even an article from the newspaper - to help keep your mind focused on something other than the discomfort.
The tiniest signs of you feeling uncomfortable terrify him. However, Yuji’s super sweet and concerned, even though a little clueless - but he’s truly trying his best.
Yuji worries that he should be able to fix everything. If you’re still in pain despite his care, he mopes quietly and mutters, “I… I wish I could do more… I hate seeing you like this.” He’s completely aware it’s irrational but can’t help feeling like a helpless failure sometimes.
He’ll almost trip over himself trying to help. When he doesn’t know how to help, he literally starts whisper-googling. You might hear, “Okay… heating pad… cramps… peppermint tea… cinnamon rolls?? Got it, got it…” before he returns with a tray of snacks and a warm compress.
If you’re emotional, Yuji doesn’t hesitate - he’ll hug you so tightly you might need to catch your breath, rubbing absentminded circles over your back to soothe your nerves. “My fighter. You’re such a brave girl.”
He genuinely feels proud if his presence, hug, or snacks prepared by him make you feel better.
Megumi notices when something’s wrong within a moment.
He won’t make a big deal out of it, but suddenly everything is taken care of. You don’t even notice when he did it.
“You should rest, Y/N.” That’s about as gentle as he gets verbally.
His Divine Dogs will do their best to comfort you as well. Kuro might curl near your feet or nudge a blanket closer with his nose, while Shiro rests his head lightly on your stomach or chest. Their presence is cozy and grounding. They are protective without being intrusive, mirroring Megumi’s own careful attentiveness.
If you lean against him for comfort, he stiffens for a moment, processing. Then, almost imperceptibly, he relaxes, allowing you to stay like that as long as you want.
When you’re frustrated or irritable, Megumi doesn’t scold or try to cheer you up. His constant presence helps regulate your mood without words, like a calm current beneath the surface.
Dramatic. Over-the-top. Surprisingly caring underneath it all at the same time.
Spoiling you becomes his immediate priority. Anything you even hint at - snacks, chocolate, tea, ice cream - he materializes it, grinning like it’s the most natural thing in the world.
Gojo will never underestimate the power of sugar, and whenever you’re on the edge of crying, he will offer you a sweet treat. “Chocolate improves morale. Marshmallows improve morale. My presence improves morale, too, so you’re basically invincible right now.”
If you want to lie down, Gojo will drop completely into full human pillow mode. You can curl against him while he rambles endlessly about nonsense, trying to distract you from the pain. Sometimes he even hums or makes ridiculous commentary just to keep your mind off cramps.
Anyone who even looks like they might annoy you during this time gets the Gojo glare. He won’t raise his voice, but his sheer presence is enough to clear a room.
If the pain gets bad, Gojo becomes quiet, almost unnervingly gentle. He’ll brush your hair back, hold your hand, or press his palm against your belly with a soft “I’ve got you. Just tell me what you need.” He hates seeing you struggle.
Higuruma notices in the same way he notices inconsistencies in testimony - small things most people would miss. The way your patience wears thinner, the slight stiffness in how you move, the way you go quiet when the cramps spike. He doesn’t pry, just studies you for a second before asking in that low, even voice, “Is it bad this time?”
He listens carefully when you explain what hurts, giving you his full attention without interruption. With Higuruma, it never feels like you need to convince him your pain is real. The moment you speak, he accepts it as fact and starts thinking of solutions.
His care is thoughtful and deliberate. Medicine is brought exactly when it should be, tea set down while it’s still hot, a heating pad adjusted with precise hands so it rests where it actually helps. Every action feels considered, like he’s already weighed what would make this easier for you.
He stays nearby in that quiet, grounding way that suits him - reading through papers, sitting on the edge of the sofa, loosening his tie while keeping you within reach. He isn’t overly demonstrative, but if you lean against him, he immediately shifts to support your weight without a word.
What makes it so Higuruma is the way he protects your peace. If someone tries to interrupt your rest or dismiss what you’re feeling, his expression hardens almost imperceptibly, and his voice turns firm enough to end the discussion on the spot. “She’s resting. This can wait.”
The second Yuta notices you’re off, his whole attention shifts to you. His brows pull together, voice soft and immediately concerned: “Are you hurting?”
He doesn’t pry, but the worry is obvious in the way he stays close, watching for any sign the pain is getting worse.
He absolutely over-prepares, but in a way that feels very Yuta: quietly gathering things one by one because he’s scared of forgetting the one thing that might help. Water, pain relief, tea, your favorite snacks, blankets, extra pillows; he’d rather look excessive than risk you needing something he didn’t think of.
Yuta stays physically close in that naturally gentle way of his, letting you lean against his shoulder or rest against his chest while his hand moves in absentminded, soothing circles along your back or arm. He doesn’t even seem to realize he’s doing it; comforting you just comes naturally.
If the cramps hit hard, Yuta gets that quiet, determined look in his eyes; the one that means all of his focus is on you. He knows he can’t simply make the pain disappear, and that frustrates him more than he’ll admit, so instead he stays with you through every wave of it, making sure you never have to sit in that discomfort alone.
The more pain you’re in, the closer Rika seems to gather. If you curl tighter with cramps, her cursed energy thickens around the room in a strangely gentle way, almost like another blanket layered over the space. Yuta notices it too, glancing briefly toward her with that soft, understanding look only he can give. He doesn’t need to say anything; Rika simply reflects his own desperate wish to shield you from every ounce of hurt.
The first thing out of his mouth is a scoff. “What, you’re out of commission because of that?” His tone is cutting, almost mocking, like he can’t believe something so mundane has you slowed down.
“Tch. Women are such a pain. Stop making that face, it makes you fucking ugly, Y/N."
He absolutely judges how you handle the discomfort of the period. If you complain too much, he’ll sneer and compare you either to women from the Zenin clan who knew how to endure in silence or to his impossible standards of grace. “At least have the decency not to look so miserable.”
Yet, in his own strange way, he still expects you to be in proper condition. Naoya will curtly order someone to bring tea, medicine, or a heating pad, acting as if your discomfort is an inconvenience to his environment.
He hates anyone else noticing your vulnerable state. Not out of tenderness but out of pride and possessiveness. The idea of others seeing his woman looking weak irritates him deeply, and he’ll shut it down with a sharp glare and an even sharper tongue. If anyone comments on your condition, though, his expression turns ugly fast. “Did I or Y/N ask for your opinion?” is usually enough to make the room go dead silent.
The closest thing you ever get to softness from Naoya is him forcing you back down the moment you try to keep going with your usual tasks despite the discomfort. His fingers clamp hard around your wrist, sharp enough to make you freeze, while his expression twists with open irritation. He clicks his tongue in disgust. “Know your place. If you’re going to slow everyone down, at least stay out of the way.” The words are cutting, full of that familiar disdain he reserves so easily for women yet he never strays far, lingering just close enough to make sure you obey and actually stay put.
He notices fast. Toji is the kind of man who clocks the smallest changes in your body language; the way you move a little slower, the faint grimace when you sit down, the shorter fuse in your tone. He won’t ask if it’s your period. He already knows. All you’ll get is a sideways glance and a low, dry “That time again, huh?”
His care comes in actions, never words. A pack of painkillers lands beside you, followed by a bottle of water he cracks open first because he knows you’re not getting up. If there’s nothing decent to eat around, he disappears for a bit and comes back with something warm, and filling.
Toji isn’t the type to fuss, but he does subtly rearrange things around you. The blanket you like is suddenly within reach, the room is quieter. He makes comfort happen without ever talking about it.
If the cramps are bad enough that you’re curled in on yourself, he’ll click his tongue, sit down beside you, and tug you against his chest or side with a rough “There, there, it will pass soon.” The steady heat of him and that solid frame are exactly what you need.
Anyone who bothers you gets dealt with instantly.
