Pairing: Kirishima x Fem!Reader
Featuring: Class 1-A Babysitting Chaos
Genre: Pure Crack, Full Ensemble, Epic Finale
Summary: In a desperate bid to prove they’re “hero-ready,” Class 1-A volunteers to babysit together. Team effort, they said. It’ll be fine, they said. But nothing—nothing—could prepare them for one baby and her Quirk: Mass Gas Destruction.
---
“You guys SURE about this?” Kirishima asked, holding your baby like she was the final boss.
The entire 1-A squad stood in formation—matching shirts, notebooks, snacks, and Mina with a whiteboard battle plan.
“This baby’s just a baby,” said Denki, already sweating but smiling. “We’ve survived finals!”
“She’s literally two feet tall,” Mineta scoffed. “What’s the worst she can—”
PFFFFFT.
The baby made direct eye contact with him as it echoed.
Everyone froze.
Bakugo walked by the door, still emotionally scarred. “Don’t say I didn’t warn you,” he muttered. “Little demon’s got a Quirk worse than mine.”
---
Phase 1: Attempt Diplomacy
Iida read a book aloud. Momo sang softly. Tokoyami played ominous jazz on a toy piano.
The baby?
She waited.
Ochaco: “She’s so quiet…”
Tsuyu: “Too quiet.”
PHBRRRRRT.
Half the team hit the deck.
“WE'RE UNDER ATTACK!” Kaminari screamed.
---
Phase 2: Divide and Conquer
Jirou and Ojiro tried calming her with lullabies.
Kirishima and Mina tag-teamed diaper duty.
Sero built a fart-proof barrier with tape.
The baby? She broke through it.
“HOW DID SHE BREACH THE TAPE LINE?!” Sero yelled, diving for cover.
“THIS ISN’T TAPE-RESISTANT GAS!” yelled Yaoyorozu, sketching a hazmat blueprint midair.
---
Phase 3: Full Meltdown
A fart rolled across the room like thunder.
Ashido screamed, “EVACUATE THE FLOOR!”
Todoroki used ice walls. She melted them with a warm, low pbbbt.
Bakugo peeked in again. “Still think this was a good idea?”
“LEAVE,” screamed Denki, wrapped in a baby blanket and crying.
“I can’t feel my legs,” muttered Mineta from under the couch.
“I think she farted my Quirk offline,” Deku whispered, stunned.
---
Final Phase: Acceptance
Aizawa arrived to find the class scattered like a lost battle scene.
The baby sat in the center, giggling and reaching for her pacifier, a picture of peace after the storm.
“I see she won,” he said.
“She always wins,” Kirishima groaned, gently scooping her up.
“She’s gonna be a future Number One,” Todoroki murmured, still clutching a Febreze can like a sword.
The baby looked around.
Smiled.
And let out one final, echoing toot.
---
Epilogue:
She grew up to be a kind, strong, powerful young girl.
…Her Quirk? "Pressure Release" – a combustion-based gas emission with trajectory control.
Pro Hero Name: Windbreaker.
Bakugo never recovered.
Kirishima was proud.
You? You carried Febreze in your hero utility belt—forever.
The End.

Warnings// Mild description of birth, a miscarriage, but anything else is just fluff!
AGED UP AU!
TELL ME IF YALL WANT MORE LIKE THIS
-When you first told him the news it looked like he was gonna pass out, he was excited to be a father again, but also scared that yku were gonna loose this one too.
-When you're pregnant, he will do his best to protect you, like he will literally baby proof every little thing in your house just so you or the baby don't get hurt. (SO SWEET😭)
-He will always have a hand on the tummy to check if it's alive and well, when he sees you waddle in your house he immediately follows you and walks behind you just so you don't fall because he can't handle another miscarriage.
-When you have morning sickness he will do his absolute best to make you food that doesn't make you nauseous.
-His friends from UA will always come to check up on you or visit you, to make sure everything is okay. Even bakugo visits sometime, to see the little gremlin he was gonna he an uncle to.
-His mother LOVES you, and she's really excited to be a grandmother. She always helps you when izuku isn't home because of patroling or work, theres so many times where you've had a false contraction and she immediately falls into panic but at the end everything gets sorted out.
-She also often just visits without asking to check on how everything's going, izuku has given up on deciding when his mother can visit because he knows it's a conversation he cant win.
-At night you often have nightmares because of your last miscarriage, izuku wakes up to you whining in your sleep and tossing around. He puts his arms around you and strokes your belly slowly while telling you sweet words of comfort.
-When your labour started you didn't know how to react, firstly some liquid spilled out and you got confused, then after a few minute's a strong wave of pain washed over you, that was when it clicked.
-You quickly grabbed your phone and dialed Inko's number, telling her what had happened in those few minutes. I'm not kidding, in under 3 minutes she already was bursting throught your door with a panicked expression her face. She quickly called an ambulance and sat you down in the sofa to steady your breathing.
-Just like izuku, she mumbled very much. You had to stop yourself from yelling at her. When the ambulance arrived, she quickly helped you get up and walk towards the door before some paramedics took care of the situation. While you and inko were seated in the ambulance (you laying in the bed thingy) she kept reassuring you that everything would be okay and that the birth would go well.
-Inko already had called izuku about your condition but he wasn't answering, probably because he was very busy at the time. As you arrived to the hospital the contractions got so much worse, you swore you saw jesus bringing you to the other side for a second.
-As the nurses made you comfortable in your room you couldn't help but worry about izuku, did something happen that made him unable to answer your calls? Did he get seriously hurt? So many questions flowed your head which worried you.
-As time passed you got more and more dialted and the contractions became closer and closer. Inko warned the nurses and made them look after you and check up on you. Panic set your body as you were told how far you were dialated. 10 centimeters.
-more time passed and soon you were laying in the hospital bed, cussing and throwing a curse on the poor nurses and inko that surrounded you, but what could you say? Labour hurt.
-Your whines and sobs quickly quieted down as a loud cry filled the room, you looked down to see a crying baby that flared It's arms in the air. It's face was red and angry as air filled It's lungs, it was covered in many different liquids and had a good pair of lungs.
-The nurses washed and packed the baby in a soft blanket before handing it to you, soon after the birth, you found out it's gender. A beautiful baby boy.
-You leaned back with your baby in your arms, his cries quietly calming down as soft coos came out of his mouth. Even if it hurt it was worth it.
•Some time later•
- Inko sat in a chair close to the bed where you were laying on sleeping, her peaceful snores echoing thought the room.
-Suddenly, a loud phone call was heard coming from Inko's phone placed on the table next to where she was sitting. The contact calling her was named as "my sweet munchkin" which you chuckled at, it was of course your beloved husband.
-But unfortunately the loud ringing woke up your baby, his face scrunching up before beginning to wail loudly. Inko picked up the phone and answered with a little "Hello?"
-Izukus panicked voice could be heard in the background, talking about how he was on his way to the hospital and asking if you were fine. It made you snicker.
-When he arrived to your room he couldn't help but fall to his knees crying happy tears when he saw the baby, your sons eyes were green while he had your hair color. It was everything izuku wanted.
-He moved closer to where you sat, gently picking the baby out of your arms to hold his son himself. He sniffled as he buried his face into your shoulder.
This was his happiest day of his life
Comment If you want me to do more characters!:)
Edgeshot prided himself on precision—both in the field and in life. He had slipped in and out of the hospital with the skill only the #4 Pro Hero could muster, careful not to attract attention. The media didn’t know. The commission didn’t know. Not even his closest colleagues.
And that’s how he liked it.
This was his peace—his sanctuary with you and your newborn son. And he wasn’t ready to share that with the chaos of the hero world.
Unfortunately, fate—and Present Mic’s big mouth—had other plans.
---
It started innocently enough. A casual patrol meeting at the agency. The usual crew—Endeavor, Mirko, Best Jeanist, Hawks, and of course, Present Mic—sat around the table throwing back caffeine like it was oxygen.
Edgeshot stood at the edge, arms folded, face unreadable as always. Calm. Controlled.
Until Hawks strolled in late, twirling a familiar beanie in his hand.
"Yo, Shinya," Hawks said with a smirk, holding up the tiny gray hat with a small embroidered duck. "You, uh, drop this?"
Time stopped.
Edgeshot's eyes flicked to the beanie. His son’s beanie.
"...Where did you get that?" he asked, voice perfectly flat.
"I was flying by the hospital yesterday. Saw a nurse wave it around outside the window. Said someone left it. Had a tag inside that said ‘Shin Jr.’," Hawks said with an exaggerated shrug. "Figured it was a sidekick or... surprise, surprise?"
The room went silent.
Then:
"No way," Mirko laughed, sitting up straight. "Edgeshot has a baby?!"
Best Jeanist narrowed his eyes thoughtfully. "Hmm... That would explain the recent increase in tactical leave. And the softer demeanor."
"You’ve been smiling lately," Endeavor grumbled, clearly offended by the idea of anyone having joy.
Present Mic practically leapt out of his chair. "OH MY GOD, SHINYA'S A DAD?!" he howled. "WHY DID NO ONE TELL ME?!"
Edgeshot, surrounded and betrayed by a single forgotten beanie, let out a long sigh through his nose.
"...Yes," he said quietly. "I have a son. His name is Ren. And I’d prefer to keep it private."
The teasing exploded instantly.
"Uncle Jeanist has a nice ring to it, don’t you think?" Jeanist mused.
"I CALL GODMOTHER!" Mirko yelled, punching the air.
"Does he have wings like me?" Hawks teased, tossing the beanie back.
Present Mic was already brainstorming a baby shower playlist.
Edgeshot stared into the middle distance, wondering if he could sew his vocal cords into a noose.
---
Later that night, he returned home, your baby curled peacefully on his chest as he recounted the day’s chaos.
"They know now," he murmured to you, gently stroking your son’s head.
You laughed softly, brushing hair from his face. "You knew they’d find out eventually."
"I was hoping for at least six months," he said with mock despair. "Now Jeanist’s talking about matching denim for toddlers."
You snorted. "Better than Endeavor suggesting fireproof diapers."
He smiled—soft and small—and leaned his head against yours. In the background, your son stirred and sighed, clutching the edge of Edgeshot’s hero cape like it was his whole world.
Let them tease. Let them laugh.
Because now they knew exactly what he was fighting for.
Can you make a fanfic about class 1A, but it's Omegaverse? Like fantasy too. And reader is the only Omega. And that they have tails and ears. You can choose yourself what animals represent each secondary gender.
The wind howled through the trees, its chill biting at your skin, but the warmth from the bustling students of Class 1-A kept you grounded. Today was different. Today, you could feel it—an undercurrent of change, something stirring in the air, beneath the surface.
You had always been the only Omega in your class, and even in a world where quirks and powers were as common as the very air they breathed, being an Omega was still a rarity. Most people thought of you as fragile, but they had no idea what it truly meant to live in a world where instincts ran deep, and your body was constantly at odds with your desires.
You had animal features that set you apart from the others: a pair of soft fox ears perched atop your head and a long, sleek tail that swayed behind you, a constant reminder of your primal side. Your scent was subtle but alluring, a combination of wildflowers and earthy musk, and it had always been a source of fascination for your classmates.
Today, however, there was something more—something deep within you that made your senses sharper, your instincts wilder.
---
It was lunchtime, and Class 1-A had gathered in the common room to eat. As you sat by the window, quietly nibbling on your lunch, you couldn’t help but notice the subtle glances your classmates sent your way. They tried to hide it, but the way their noses flared or their postures stiffened didn’t go unnoticed by you.
"Hey, [Y/N], are you alright?" Midoriya’s voice pulled you from your thoughts, his wide eyes full of concern.
You smiled softly at him, though there was a tension in your chest that you couldn’t shake. “I’m fine, Izuku. Just… feeling a little strange today.”
Bakugo, who was sitting across from you, snorted. "Quit being so dramatic. You’re fine, right?" His voice was gruff, but there was something strangely soft in his gaze. You weren’t sure if it was his natural alpha dominance coming through, or if it was just concern disguised as irritation.
But you could feel it too, Bakugo. You could feel the subtle shift in the air around you, the growing tension, the unmistakable presence of rut approaching.
---
As an Omega, the instinct to submit during rut was something that couldn’t be ignored. It was natural, and while you had never experienced it firsthand before, you could feel it stirring deep within your core. The closer you got to the day, the more your body reacted to the alpha pheromones in the air, the more your tail twitched in response to their presence. It was always a silent, unspoken bond between alphas and omegas—an instinct that only became stronger as the rut drew nearer.
You could feel their eyes on you now, and it wasn’t just because you were the only Omega—they could smell it, too. The pheromones you released were subtle, but to them, they were like a beacon. Each of the alphas in the room was aware of your presence, and they were struggling to keep their instincts in check.
You turned your head to see Todoroki's eyes narrow slightly, his sharp gaze flickering from the corner of his eye to your face. He was a rare alpha, a dual-quirked one with the power of ice and fire, and his presence was both soothing and intense. His left side was the fire side, often tempered and controlled, while his right side, the ice, was always more relaxed, colder. But right now, you could see the flame in his eyes—a sign that his instincts were flaring.
The temperature in the room seemed to rise, despite the coolness outside, and you felt the heat of it press against your skin, making your breath quicken. You stood, trying to compose yourself.
“I think I need some fresh air,” you mumbled, barely able to focus on your words as you headed toward the door.
Before you could step outside, you felt someone close behind you, their presence undeniably strong. Bakugo’s voice broke the tension, low and gravelly. “Where do you think you’re going, [Y/N]?”
You froze, your tail twitching as the sharp scent of his alpha pheromones hit you hard. It wasn’t just the usual arrogance you were used to from Bakugo. No, it was something primal. Something that made your heart race and your body pulse with heat.
“Bakugo…” you began, but your voice wavered, a shiver running through your spine.
“Stop acting like you’re the only one who can feel it,” he growled softly, stepping closer to you. His hand reached out, lightly brushing the tip of your tail, making you gasp and step back instinctively. His touch was almost too much to bear. “We all know what’s coming. Don’t try to run from it.”
Todoroki’s voice was colder, cutting through the tension like a knife. “Bakugo, don’t push them.”
You looked between the two of them, your mind clouded with the rising pressure of your instincts. The scent of fire and ice mixed with your own, the pheromones creating a storm in the room that made everything feel so much more intense. It wasn’t just the rut—it was something deeper, something more primal than any of you had expected.
“I—I don’t know if I can control it,” you whispered, your fox ears flattening against your head. “This… this feeling inside me, it’s getting stronger.”
Your tail was swishing nervously, caught between the instincts to flee and the urge to stay close to the alphas. You could feel it now, the pull of your Omega instincts, calling out to their dominant presence.
“I won’t let you run away,” Bakugo snarled, his eyes narrowing, the heat of his alpha aura almost suffocating. “You don’t get to hide. Not this time.”
The air between you crackled with tension, and suddenly, everything felt so much more real. The ruts, the pheromones, the undeniable urge to bond—everything was rushing toward a breaking point.
You closed your eyes, your head spinning with conflicting emotions. "I can't…" you breathed.
Before you knew it, you were caught between the two alphas, each with their own distinct scent that threatened to overwhelm you. The weight of their presence, their alpha nature, sent a thrill through your body, and it was impossible to ignore.
But then, a third presence made itself known.
“Enough,” a smooth, calming voice interrupted. “This isn’t the way.”
You opened your eyes to see Todoroki stepping forward, his calm and measured demeanor cutting through the intensity. “We need to control ourselves. [Y/N] is right to be cautious. But we will help them, not push them.”
Bakugo didn’t like it, but he huffed, the tension in his posture easing, though the fire in his eyes never quite dimmed.
You exhaled a shaky breath, feeling your heart rate slow, but the storm inside you hadn’t passed. The rut was coming, and you could feel it—the alphas' instincts, your own, all pulling in the same direction.
And you, the only Omega, were the center of it all.

◇
You grunted as the hard and big sharp blade pierced and dragged down your arm multiple time's, blood trickling down all the way to the bottom as you heard the drops of blood hit the ground. Your breath was uneven and your hands and whole body shok, probably because of the sharp object injected into your skin. You didn't know why you did it, but it just felt right.
A few moments passed before you walked towards the bathroom to wash of the remains of the blood on the blade, the bathroom door creaked as you pushed it aside.
You took a cloth that hung on the small metall bar beside the shower and carefully wiped the blade, being carefull to clean everything off and not to cut your finger.
You laid back the cloth and walked back towards a drawer next to your bed, you gently and carefully placed the blade into one of the shovels.
You sighted as you looked at your arms, blood dripping out of the hem of it, you'd probably have to bandage it because of the cuts, but then you'd have to go downstairs to get some from thr medkit in the small box that was hung on a wall inside the kitchen and then everybody would suspect something going on.
You didn't want to start commotion, that was the least you needed right now. You had a few cotton pads in a tall glass next to your makeup shellf and you also had a box of wipes under your desk so you didn't have to worry about those things.
"Hmm... maybe i should just ask katsuki he usually doesn't question things unless he gets suspicious, and most of the times he had to bring something to you he never asked why you needed it"
You told to yourself.
And if he got suspicious, you could just say something happened at training, right?
You walked to the bed and sat on it, quickly grasping your phone and pressing on Bakugo's contact.
"Can you bring me some bandages plsss"
You typed and laid down the phone, waiting for a response. "Bling" was suddenly heard and you picked up the phone.
"Tch, are you too lazy to to downstairs or somethin"
"Just get it for me asshole"
"K, fine."
A few moments later bakugo knocked on ythe door and you sprinted quietly towards it, you opened the door halways so he wouldn't see your bloodied arms.
"Here ya go, take the the bandages, but why do ya even need it in the first place"
"Oh uhm, something happened at training today, it's nothing serious but my "wound" opened up again, but anyways thanks for the bandages!"
He frowned and made a "tch" sound before he turned on his heels and walked away. You rolled your eyes before closing the door. You gathered all the things you needed to clean and bandage the scars.
First you put some water on a few cotton pads and softly wiped the bleeding cuts with it, then you grabbed a pair of wipes and carefully wiped of the water. Finally you picked up the bandage roll and cut off a small piece, you carefully wrapped it around your arms.
After everything was done you cleaned up everything around you, washing away the drops of blood on the floor and changing into your night clothes.
You checked your phone before placing it on your night table and pulling the blanket over your body.
Hours passed and soon sunlight beams became vissible shining strongly throught the curtains. You woke up and groaned as you sat up and rubbed your eyes, your memory refreshing as you thought about how much damage you did yesterday.
You raised your arm as a sudden pain stung you, you whinced and groaned as you shut your eyes closed. A sight left your mouth as you stood up and walked towards your closet, you grabbed your uniform and walked towards the bathroom to change.
When you were done you did light makeup look with mascara, lipgloss and a tiny bit of blush. You smiled at your outfilt, you put your books in your bag and made sure you looked fine before heading downstairs to eat breakfast.
When you arrived downstairs you saw some of your classmates already sitting around a table, they shoot you a glance and waved at you to come closer. You took quicks steps towards them and sat down next to mina.
"Hey girl! What took ya so looooong, it was getting boring without you"
She said as she took a bite out of her cereal earning a chuckle from you.
"Sorry sorry! I guess I lost track of time, I promise!"
"Hmmm, are ya sure you weren't making out with bakugo or something like that"
She smirked as the people around you quickly widened their eyes and shoot bakugo and you a glance. Your mouth widened and your eyes raised, bakugo quickly looked at mina and shot her a big frown, IIda's eyes looked like they were gonna pop out if his scull, momo put a hand on her mouth and sero smiled playfully.
"WHAT THE HELL RACOON EYES"
"H-HUH"
"Oh god"
"THAT IS HIGHLY INAPPROPIATE"
Your cheeks flushes with a red tint and you quickly tried to change the topic of the talk.
"That didn't happen, I promise!"
"Hmmm, fine fine I belive you but next time I'll catch you"
"You sure will"
You said while chuckling.
A few minutes later you checked the watch on your wrist, a few minutes left before class was starting. You put your breakfast in your backpack before rising up from your seat.
As you took some steps you heard mina say your name
"Y/n? Why didn't you eat your lunch, you didn't even take one bite"
She asked with a confusing look on her face.
"Oh uhm, im not really hungry right now, feeling a little nauseous so just might wait til dinner"
Katsuki took a notice in this but didn't say anything as he watched and listened to your conversation with the pink haired girl.
"Oh okay, hope you get better, we better get going to class too, mind if we walk with you to class?
"I don't"
You smiled as you watched her and the others stand up, throwing away the remains of the breakfast in the trash before following you to class.
Some hours later you're in your fourth period, your scars itched and were begging to get itched. Your brows furrowed in irritation, your homeroom teacher, shota aizawa took a notice in how your brows had furrowed in almost each period.
He walked to your desk and bent down with his hands on each side of the table.
"L/n what's wrong, and don't you dare say nothings wrong because I've noticed your face rhythms so tell me"
You looked up at his sharp face studying your every move.
"Uhm, nothings wrong what do you mean"
"L/n."
He stated strongly, "don't you lie to me"
"I'm fine, don't you worry"
He grabbed your arm before watching you whince and groan as you pulled your arm back in a fast motion holding it with your other arm.
He slowly pulled his arm back and looked at it.
"Why did you-" He stopped talking when he noticed something red spilled under your left arms hem.
You widened your eyes and swallowed your saliva, watching his eyes following your gaze. You hid your arm under the desk as you waited for a reaction.
"L/n, let me see" he spoke in a dark tone as his eyes darkened.
Your lips shivered as you shook your head, you didn't have time to react before he snatched your arm back and pulled your shirt around the arm back.
He stopped when he had pulled it away, looking at the cuts around your arms. Some were small, other were looking like a normal cut you would get from getting scratched from a cat or something like that, but what really worried aizawa was the three very big cuts bleeding on the top of your arm near the elbow.
"What the h-hell" he stuttered, his eyes wide.
"Tell me what happened right now, i know damn well this injury didn't happen during training"
Your throat got dry and you struggled to find the words to explain and make up a new lie.
"TELL ME RIGHT NOW"
Aizawa shouted as you flinched and turned your head away, other students heads turned your way and looked worried for Mr Aizawa's outburst.
They locked eyes with where aizawa's were staring and many eyes widened, including bakugos,
It dripped a little more than a normal cuts would bleed, plus an injury couldn't make so many cuts in different places.
"Y/n..."
Bakugo said your name slowly as he raised up from his desk, his normal grin or smirk replaced by an angry-worried expression.
He slowly walked towards you.
Shit, this wasn't supposed to happen.
TBC?
The soft hum of the hospital room filled the silence between you and Izuku. You lay propped up on the pillows, tired but glowing, as you watched your husband sit frozen in the nearby chair, staring at the bundle in his arms like it was the most sacred thing he’d ever held.
“Are you okay?” you whispered with a tired smile.
He looked up at you, eyes wide, already glassy with emotion. “He’s… he’s so small. I’m afraid to move.”
You laughed softly, your hand brushing your own tired eyes. “You’ve held babies before.”
“Yeah, but not ours. Not my son.” Izuku looked back down, his hand cradling the baby's head like he was made of paper. “He’s got your nose… and I think my ears.”
The baby gave a tiny yawn and wriggled in his arms. Izuku froze.
“Did I do something wrong?!”
You shook your head gently. “No, love. He’s just dreaming. You’re doing everything right.”
Izuku sat completely still, not even daring to shift his weight. His hair was a mess, his hero uniform jacket thrown over the hospital chair behind him. He hadn’t left your side once.
“I don’t know how to do this,” he admitted quietly, “but I know I want to do it perfectly.”
“You don’t have to be perfect,” you said, voice growing soft as sleep pulled at you. “Just love him. Like you already do.”
His eyes softened. “I love you both so much it hurts.”
As the baby settled in his arms, Izuku slowly stood up, walking carefully to your bedside. He sat beside you, cradling your son between the two of you.
“He’s going to be so brave,” he said in a hushed tone. “But I’ll be careful. I’ll be gentle. I’ll protect him with everything I have. Always.”
You leaned your head on his shoulder, your fingers brushing over the baby's blanket. “He’s got you. He’s already safe.”
In the quiet of the hospital room, with the city far outside and the world on pause, Izuku Midoriya held his son like he was holding the whole future.
And to him, maybe he was.

Pairing: Kirishima x Fem!Reader
Featuring: Babysitter Mina Ashido
Genre: Crack fluff, Chaos, Girl Power vs Baby Gas Power
Summary: After hearing the legends of Baby Boom, Mina insists on babysitting. Confident. Fearless. Fabulous. She walks in like it’s a spa day. But this baby has no mercy—and Mina’s about to find out that cute pink hair doesn’t protect you from napalm-level toots.
---
“Guys, please,” Mina waved her hand dramatically as she slid her sunglasses down. “How bad could one tiny baby be?”
Kirishima and you just stared at her.
“Bakugo almost cried,” you offered gently.
“Deku said his lungs aged five years,” Kirishima added.
“Todoroki won't make eye contact with any infants anymore,” you finished.
Mina grinned. “So she’s a little spicy. I’m spicy. We’ll vibe.”
You handed the baby over. She cooed. Mina winked.
"Girls stick together," Mina said proudly.
From the hallway, Kirishima whispered to you, “We should start a timer.”
---
T+10 Minutes:
Mina was dancing in the living room, holding the baby like she was in a music video.
“We’re thriving, girl!” she sang. “Look at you! A queen! A tiny, powerful queen—”
PFFFFFFFFT.
She froze. The baby grinned.
“Okay,” Mina said slowly. “That was... assertive.”
She sniffed.
“Oh no.”
---
T+18 Minutes:
Mina had relocated to the balcony.
“I’m not saying I’m scared,” she said aloud, talking to the baby like a roommate. “But I did just Febreze your diaper like six times. And you’re still going.”
The baby tooted again. Long. Proud. Musical.
Mina blinked. “That one had a melody.”
She pulled out her phone. “Group chat. Emergency. I’m being farted alive.”
---
T+30 Minutes:
Kirishima peeked through the window.
Mina was standing in the middle of the living room like a war general, armed with lavender incense, baby wipes, and a fan in each hand. The baby sat smugly in a bouncer, thumping her legs like a war drum.
You sipped your drink calmly. “She’s gone full tactical.”
Kirishima whistled. “I’ve never seen Mina sweat before.”
PHHHBBT.
Inside, Mina yelled, “I DON’T DESERVE THIS!”
---
T+50 Minutes:
When you returned, the scene was… dramatic.
Mina was lying flat on the couch, a cold washcloth over her forehead.
“She won,” she mumbled. “I tried… I really tried.”
The baby was sound asleep in her arms, looking peaceful—like she hadn’t just gas-bombed a fully trained pro hero.
Kirishima picked her up and sniffed cautiously. “She’s… calm now?”
Mina sat up slowly. “She was never mad. That’s the worst part. She enjoyed it.”
You patted her shoulder. “She respects you now.”
Mina exhaled. “Good. She can remember that next time, when I show up in hazmat pink.”

Next time: Sero and Denki want to babysit together.
You were a strong, independent aspiring hero. You’d faced villains, explosions, and Bakugo’s screaming. But none of that prepared you for the wildest opponent yet…
…a wisdom tooth extraction.
You blinked awake, mouth stuffed with gauze, brain foggy, and vision blurry. The fluorescent lights above you hummed like a villain’s theme music. Was this Tartarus?
“She lives!” a dramatic voice shouted. That was—oh god—Denki Kaminari, filming you on his phone.
“GET THAT CAMERA OUTTA MY EYE SOCKET!” you bellowed. Or at least, you thought you bellowed. It came out more like: “Geff dat camma outta my faysalkit.”
Mina popped into view, laughing hysterically. “Girl, you sound like you’re summoning demons!”
You tried to sit up. “Iz dis… is dis my quirk? Am I… a duck?”
“Honestly? Maybe,” said Kirishima, gently pushing you back down. “You’re being super unbreakable right now, though. Respect.”
You squinted at him. “You got… rocks for skin. Are you okay? Like emotionally?”
“Wow, even under anesthesia, she checks in on us,” Tsuyu said calmly from the foot of the bed. “That’s kinda sweet.”
“I love all of you,” you mumbled dramatically, reaching for Todoroki’s face. “Especially you, Mr. Ice-and-Fire Cream Sandwich…”
“…I’m gonna pretend that was a compliment,” Todoroki muttered, letting you poke his cheek with your numb finger.
Bakugo, leaning against the wall with his arms crossed, muttered, “This is the dumbest thing I’ve ever seen. She’s a disaster.”
You gasped. “You take that back, Kacchan! I’m a beautiful disaster.”
The gauze puff in your mouth fell out mid-monologue and Denki nearly dropped his phone laughing. “We’re keeping that. That's going in the group chat AND your graduation video.”
Finally, the nurse arrived to check on you, only for you to gasp and shout, “WAIT. AM I STILL A DUCK?!”
“No, sweetie. You're not a duck.”
“...Disappointing.”

Dinner started off normal.
You made katsudon (Bakugo’s favorite). Haruki was unusually quiet. Hana had a suspicious smile. Bakugo was halfway through his second helping, blissfully unaware of the emotional landmine about to detonate.
You should’ve known.
You should’ve known.
It started with Hana.
“So, I think Takeshi might ask me to be his girlfriend.”
Bakugo froze mid-chew. “He better not.”
You gave her a soft smile. “That’s exciting, sweetheart.”
Bakugo narrowed his eyes. “No it isn’t. It’s illegal.”
Haruki jumped in, mouth full of rice. “Takeshi’s not that bad. Better than closet girl.”
Bakugo dropped his chopsticks.
“You wanna repeat that?”
Haruki realized too late that he’d just outed himself. Again. “I—I mean, hypothetically—”
“You were back in the closet?!”
You groaned. “Oh my god, not again.”
Hana leaned back smugly. “I saw them holding hands yesterday.”
Haruki turned bright red. “TRAITOR!”
“She winked at him too,” Hana added, like she was announcing a war crime. “Both eyes.”
Bakugo stood so fast his chair screeched. “THAT’S IT. This dinner is OVER. Everyone to their rooms. No more hormones. NO MORE WINKING.”
You tried to intervene. “Katsuki—”
“Nope. I’m done. I gave the talk. I suffered through The Incident. I read the damn Diary. I survived ClosetGate. And now you’re telling me I’m raising a Romeo and Juliet sequel in my own house?!”
Haruki mumbled, “Technically we’re more like a Rom-Com—”
“SHUT UP, HARUKI.”
Hana, cool as ever, kept sipping her juice. “Don’t worry, Dad. It’s not like I’m gonna kiss him on school property.”
Bakugo wheeled on her. “YES YOU ARE. AND I’LL BE THERE. HIDING IN A BUSH WITH BINOCULARS.”
You snorted so hard you choked.
Haruki tried to sneak another bite of katsudon.
Bakugo caught him mid-chew. “You think you get to eat after all this betrayal?!”
“Dad,” Haruki said around a mouthful, “you need therapy.”
“I need a flamethrower.”
---
Ten minutes later, you were cleaning the kitchen while Bakugo sulked in the corner like a war veteran.
“I can’t do this,” he muttered. “We’re surrounded. Outnumbered. Hormones on all sides.”
You kissed his cheek. “You’ll survive.”
“I miss when they were babies. When they only cried because they wanted snacks, not because some punk told them they had ‘pretty eyes.’”
You laughed. “You’re doing great.”
“I’m dying.”
“You’re surviving.”
He groaned. “Same thing.”
Question would you do a class 1-b of the explosive love or is it truly over? (my lungs have been full of laughter from it all)
A/n, I added jiro bc, why not🫡
Pairing: Kirishima x Fem!Reader
Featuring: Class 1-B and Their Unique Babysitting Experience
Genre: Chaos, Crack Comedy, Baby Gas Wars
Summary: After hearing about the legendary struggles of Class 1-A, Class 1-B believes they can handle things way better. They don’t need a plan—just confidence. Spoiler: They were wrong. Very, very wrong.
---
“We’ve got this!”
Kendo, confident as ever, waved her hand as she stared at the baby in Kirishima’s arms. “Class 1-B doesn’t need a fancy strategy. We’re heroes in training. This is nothing!”
Tetsutetsu pumped his fist in the air. “Yeah! We’re tough enough to handle anything!”
“You guys sure about this?” you asked, looking at your baby, who was already cooing and glaring in their direction.
“Totally! We’ve got teamwork! We’ve got brains!” Kendo grinned, a little too widely. “Let’s do this!”
Kirishima turned to you and whispered, “Should we warn them?”
You shook your head. “Let them learn the hard way. We survived this chaos. They will, too.”
---
T+5 Minutes:
The plan was simple: Kendo would handle the baby while the others prepared snacks and games.
“Alright, little one!” Kendo smiled down at the baby. “Ready for a fun day?”
The baby gurgled and farted.
“Hmm,” Kendo raised an eyebrow, but she pressed on. “That’s a little... unexpected. No biggie, though.”
PFFFT.
The others exchanged nervous glances.
“That was... powerful,” Ibara murmured.
Kendo, ever the optimist, ignored the baby’s warning signs and decided to try a gentle lullaby. “Hush little baby...”
PHBRRRTT.
Kendo paused, her smile faltering.
“That one had vibration,” Ibara noted, raising an eyebrow.
“Okay, okay,” Kendo said, trying to keep her cool. “Maybe she’s just gassy. No big deal. Just... relax.”
---
T+12 Minutes:
The whole team was huddled in the living room now. Kendo was still holding the baby, though the team had taken up defensive positions.
Manga began sketching diagrams of escape routes. “I think we need a plan B... and C... and maybe D.”
Tetsutetsu, trying to impress, stood by with a bottle of milk. “Maybe this will help calm her down! I’ve got this!”
The baby eyed him suspiciously.
PFFFT.
Tetsutetsu jumped back like he’d been hit by a rocket. “WHAT THE HELL?!” he yelped, clutching the bottle like a shield.
Kendo sighed. “Okay. So, we’re not handling this as smoothly as I thought.”
---
T+22 Minutes:
Jurota was in charge of distracting the baby with toys while Kendo attempted a strategic diaper change.
“Jurota, you’ve got this, right?” Kendo asked, holding up a toy rattle. “She’s really into sound, so just—”
Before she could finish, the baby farted again. This time, it was a long one.
Jurota, who had been holding the rattle, dropped it and quickly backed away.
“I didn’t sign up for this! I thought it was just a normal baby!” Jurota cried, his face pale.
“I swear she’s aiming for me,” Tetsutetsu shouted from behind the couch. “I feel the pressure!”
---
T+35 Minutes:
The room was now a war zone.
Kendo, the ever-hopeful leader, was sweating. “We need to regroup,” she muttered. “We need... We need a strategic intervention!”
The baby, sensing weakness, let loose.
PFFFT
PBRRRRTTT
PBBT-TSSSSSS...
Kendo held her hands up. “Okay! We need a team effort! Shoji, you try distracting her with your extra arms. Ibara, you handle the snacks. Jurota, keep it together!”
Ibara carefully arranged some snacks. “I don’t think snacks are going to help this situation.”
“I’m gonna pass out,” Jurota groaned. “Is she cursed? Is this a curse?!”
Meanwhile, Jiro was completely overwhelmed. “Guys, I don’t have a soundproof speaker for this level of... chaos.”
Manga finally gave up and wrote: “Subject: baby. Threat Level: Explosive.”
---
T+45 Minutes:
Kendo had lost all hope.
“I’m sorry, I was too optimistic,” she muttered.
The baby looked up at her with big, innocent eyes and let out one final, massive fart.
Everyone in the room flinched.
“THAT’S IT! I CAN’T TAKE IT ANYMORE!” Tetsutetsu yelled, running toward the door. “THIS IS HELL!”
“We... we didn’t even try the baby wipes,” Kendo said softly, defeated.
---
Final Tally:
Kendo: Crushed by baby gas.
Tetsutetsu: Traumatized and refuses to even look at a bottle.
Manga: Analyzed the situation, concluded they had all made a terrible mistake.
Shoji: Vowed never to babysit again.
Jurota: Physically and emotionally drained.
Ibara: Retired from all babysitting duties.
Jiro: Still recovering from the sonic levels of flatulence.
Momo: Watching from the sidelines, unaffected, with a notebook full of new inventions for future diaper duty.
---
When you and Kirishima returned, you found Class 1-B sprawled on the floor, completely broken.
Kendo weakly raised a hand. “She’s... a powerhouse.”
“She’s a menace,” Tetsutetsu whimpered.
“And we’re never doing this again,” Manga finished, his face still pale.
The baby, in your arms, giggled.
Kirishima smiled warmly, “Good job, everyone! It’s a learning experience!”
You nodded. “Yeah, let’s never do this again.”
