Just Like Me

Work Text:

Katsuki jolted when he felt the weight hit him in the leg, and it took every ounce of his self-control to keep from blowing it up immediately. After some reluctant practice, he'd come to know what that feeling was, what was winding around his leg, and the little whines that came with it.

"Oi, kid, what are you-"

He stopped mid-sentence when he looked down, eyes locking with a strangely familiar crimson, long, dark eyelashes ridden with tears.

"Daddyyyy," she whined, burying her face in his leg. "I found you! I was scared!"

As much as he wanted to shove the kid off and insist that she had the wrong person, there was some weird twinge deep in the pit of his stomach that stopped him. Her spiky blonde hair was tied into two little pigtails, with bright red bows securing them, and her face was just so...

"I need you to answer some questions for me," he said instead, bending down to meet her eyes, setting his convenience store bag on the footpath. "Can you stop crying for me?"

She nodded, sniffing hard and scrubbing her eyes on a dirty pink sleeve.

"I know, Daddy. We gotta do security! You can go first."

"What's my name?"

"Bakugou Katsuki," she said firmly, wiping her eyes again. "What's your favourite colour?"

Katsuki paused, pulling a face.

"Green," he answered honestly. "What's your name?"

"Bakugou Hisami. Daddy these questions are too easy, a villain could know. You gotta ask a hard one!"

"Can I be honest with you, Hisami?"

"You're supposed to always be honest!"

She pouted a little, and he found himself laying his hand on her head in a strangely fond way.

"I believe you that I'm your Dad," he began, watching her eyebrows knit together. "Because you look just like me. But I think you've been hit by a quirk, yeah? Was there a fight?"

She nodded faintly, and he let out a long sigh.

"I'm still in high school, Hisami. I'm only seventeen. Do you know how old I was when I had you?"

"Twenty-five," she mumbled, taking a step back. "I'm sorry, I didn't know."

"You don't need to be sorry," he assured her. "Let's go see my teachers, okay? We'll figure out what's going on. I'm still your Dad even if I haven't had you yet, so I'll find a way to get you home, I promise."

She nodded, and Katsuki picked her up, surprised by how easily she settled herself on his hip, where he could support her with one arm alone. She tangled her hands in his school shirt, and he felt a weird pang in his chest when she rested her cheek against him, closing her eyes.

"You must have had a long day," he sighed. "Just rest."

"Can I still call you Daddy?"

"Of course you can."

On some level he hated himself for how soft he had immediately become, completely giving himself over to the little kid. If she was somehow a quirk creation to lure him into a trap, he was completely and utterly screwed.

"Hey, what's your Mommy's name?"

"Mommy?" she asked. "I don't have a Mommy."

"Oh," he mumbled, holding her a little tighter. "Sorry."

"S'okay, I don't need a Mommy!"

"Yeah, we have each other."

He didn't bother heading back to the dorms to change and put his food away, just went straight to Aizawa's office, knocking heavily on the door. Hisami cowered a little when she heard the footsteps, but when the door slid open she lit up.

"Uncle Ai!" she beamed, reaching for him happily. "You're here too!"

Wordlessly, he accepted her touch, plucking her from Katsuki's hip and hugging her gently.

"Would you like to explain this to me?" he asked Katsuki pointedly.

"I went woosh through time!" Hisami informed him, still smiling widely. "I got lost but I found Daddy! Except he's still little he's not my Daddy yet."

"She just kind of appeared at my feet," Katsuki shrugged. "Crying and relieved that she'd finally found me."

"Alright, I'll start looking into it. She can stay with me and Eri until then."

"Haah?" Hisami demanded, her voice squeaky. "I wanna stay with Daddy!"

Hisami squirmed out of Aizawa's arms, hurrying back to Katsuki's side to cling to his pant leg again.

"It's fine," Katsuki snorted. "She can stay with me in the dorms."

"Are you sure, Bakugou? Children are a lot of responsibility."

"We'll be fine. I'm sure she can tell me if she needs anything, right?"

She nodded, when he looked down at her for confirmation, and he laid his hand on her head again, stroking her hair lightly.

"Alright, I was about to go make dinner. You hungry?"

"Starving!"

"Alright, let's go back to the dorms and cook."

He hitched her up again and steadied her against his side, smirking when she shot a tiny glare at Aizawa. How dare anyone try to separate her from her teenage father, right? Little idiot.

"Daddy, I'm dirty," she complained, as they stepped out the door. "I falled over a bunch and got all messy."

"I noticed," Katsuki snorted, pointing at the grey patch on his shirt beneath her. "You can have a bath while I cook."

"You won't have a bath with me?" she pouted. "Daddy always has a bath with me."

Katsuki blushed, even his chest burning as he looked away in a hurry. He'd never thought about having kids at all, let alone taking a bath with them.

"We'll see," he mumbled finally. "I, um, share a bathroom with lots of people."

"Oh. I can't bath with them?"

"That would be weird, you little shit. You want a bunch of sixteen year old dudes to have a bath with you?"

"If they're Daddy's friends it's okay."

"No it's not, idiot. You don't let anyone do that shit, alright? It's... not safe."

"Oh."

"Just... Ask me about it when you go back to the other me, okay? He's probably better equipped to deal with this shit."

She nodded, leaning into his side again, and he breathed a sigh of relief when she stopped asking questions.

"I don't know much about you yet," he began slowly, as they trudged up the path to the building. "Um, do you like people?"

"For a little while."

"Fair enough. What's your favourite colour?"

"Red!"

"Uhh... What's your favourite thing to do? What do we do on weekends and sh- stuff?"

"You can use adult words! I know I'm not allowed to say them 'til I'm thirteen!"

"Okay," he snorted. "What kind of shit do we do, then?"

"Before school we work out!" she informed him. "We do our sit ups and our squats and our push ups, and we lift our weights, and on Sundays we go for a run!"

"Yeah? You're learning early, I'm glad."

"Sometimes if you don't have to work we go rock climbing or swimming, those are lots of fun. Papa takes me to the trampolines and the playgrounds. And for bed we read stories together!"

"Sounds like I'm an okay Dad."

"You're the best Dad!"

"Thanks, kiddo."

When he pushed open the door to the dorms, the common area fell dead silent. With a sigh, Bakugou set Hisami down on the ground, nudging her forward.

"Go on, say hello to my classmates."

"Hello!" she said brightly. "My name is Bakugou Hisami! It's nice to meet you! I need a bath!"

Immediately she was mobbed by the teenagers, surrounded by cooing, squealing bodies that knelt around her to look closer.

"Look at your eyes!" Ochako fawned. "You look just like your brother!"

"I didn't know you had a little sister, bro!" Eijirou marvelled, leaning an arm on his shoulder. "I thought you were a spoiled only child!"

"He's not my brother," Hisami pouted, her cheeks puffing out stubbornly.

"Oh, I'm sorry!" Ochako said sheepishly. "I just assumed! Cousin?"

"She's my kid," he explained, running a hand through his hair with another long sigh. "Some time travel bullshit happened, she got lost back here in our time."

"What?!"

He scooped her up again when her eyebrows knitted together, smart enough to recognise the signs from his own face.

"Hey, it's fine, they didn't know," he said softly, tucking a stray lock of hair back behind her ear. "They would know if I had a daughter in this time, right? Of course they're gonna assume something dumb."

"How did you end up with a kid?" Eijirou asked carefully. "Like, that would mean you had to...?"

"Have sex with someone?" Denki finished with a laugh. "Seems far-fetched, right?"

"With a girl," Eijirou finished pointedly. "Stop being an idiot."

"Oh. Oh!"

"She doesn't have a mother," Katsuki supplied helpfully. "I, um, don't know more than that. Hisami, do you know anything about how I got you?"

"Daddy gave his genes to a lady and she cooked me for him!" she grinned, immensely proud of herself for the knowledge. "Because Daddy doesn't like girls and boys can't have babies together without help."

"Good job, kid. You're a smart cookie, aren't you?"

"That's what Papa always says!"

"Yeah, it's what my friend used to say when I was your age."

Ochako shuffled a little closer, smiling widely when Hisami gave her the side eye for it.

"It's nice to meet you, Hisami! My name is-"

"I know who you are," Hisami pouted. "No one remembers me."

"They haven't met you yet," Katsuki corrected her. "Why don't you tell us who you know, and the others can introduce themselves?"

"I know everyone," she answered stubbornly, lifting one hand to point. "Auntie Ocha, and Auntie Tsu, and Uncle Eiji, and Uncle Pikachu."

Katsuki couldn't help but laugh, and thankfully even Denki joined in, reaching out to ruffle her messy hair.

"I'm glad you know me!" he said brightly. "I can't wait to spend lots and lots of time with you when I'm older."

"You gotta take me to the movies," she said firmly. "Every holidays."

"Say please, kid," Katsuki warned her.

"I'm not asking," she insisted. "He already did. Papa took me to the All Might movies but Uncle Pikachu takes me to the magic movies and the princess movies!"

"I love princess movies," Denki assured her. "I'll take you to see them forever and ever."

"Yeah!"

"Alright," Katsuki spoke up, shifting his grip a little, "we need a bath, so just keep out of the bathroom for a while, you hear me?"

"Got it. Have a nice bath!" Eijirou grinned. "We were just setting up to watch a movie, the others are on their way back still."

With Katsuki's little nod and Hisami's wave, they headed through to the back of the building. A load of Katsuki's washing was still waiting for him to fold and take up to his room, so he grabbed his basket and took it with them to the bathroom, finding clean clothes for himself to change into. Hisami was a different story, with her tiny stature and torn up clothing.

"I wear Daddy's clothes," she said knowingly, digging through the basket. "This one is soft!"

In her hands she held one of Katsuki's old hoodies, and he chuckled as he nodded.

"Okay, you can wear that one. Maybe we can belt it around you or some shit."

"Kay!"

With her beaten up gear thrown aside, they headed for the showers. Hisami stuck close to his side, always leaning into him or sitting on his leg as she washed herself, but somehow he didn't mind it.

"Daddy, help?" she asked, tugging at her red ribbons. "Can't do my hair."

"Yeah, I'll help," he assured her, reaching out to untie her bows. "Come sit."

She dropped in front of him obediently, and he lathered her up with his own shampoo – just as he would never settle for the cheap stuff the school provided, his daughter deserved better too. She hummed to herself as he washed it, winding ribbons around her fingers, but she turned to look when Katsuki leaned over to wash his own.

"Sorry you got my hair," he mumbled, as he loaded them both up with conditioner. "I know it's a pain."

"But I like looking like Daddy," she informed him, wide-eyed and innocent. "I don't mind!"

"Thanks, kid."

When they were clean and rinsed, Katsuki shut off the water, leading her over to the ready and waiting bathtub. It was a big one, designed for a whole group of people to use at the end of a long day, and Hisami's eyes lit up when she saw it.

"I can swim," she marvelled. "It's huge!"

"Yeah," Katsuki laughed. "You remember how?"

"Uh-huh!"

He held her hand as they stepped into the water, but sure enough she paddled like a little blonde fish, giggling as she swam around the edges of the bath. Katsuki smiled to himself as he sat back, keeping an eye on her, but mostly contemplating how the hell he'd ended up in that position.

When she started to lag, Katsuki stood up, stretching his warm muscles before he gestured toward the stairs.

"Come on, Pipsqueak. Let's go get dry and dressed."

Hisami's eyes glistened with tears when she looked up at him, and Katsuki immediately opened his mouth to apologise, wondering what the hell he'd done so wrong in such a hurry.

"Daddy," she sobbed, wiping her eyes uselessly with a wet hand.

"What did I do? C'mere."

He pulled her in for a hug, and she shook her head, wrapping her arms tight around his neck.

"You called me Pipsqueak."

"Oh, you don't like that? I'm sorry."

"That's what you always call me!" she explained, sniffling against his shoulder. "I missed it."

"Oh. Are these happy tears?"

She nodded, and Katsuki cracked a smile, stroking her hair lightly as they hugged.

"You should have told me, dummy. How am I supposed to know what you want if you don't say it?"

"I didn't want to make you say it," she insisted. "I'm just happy you still thought it."

"It suits you. You're tiny and you squeak a lot."

"I do not!"

Katsuki laughed at her indignance, wiping the tears from her cheeks with his thumb and giving her a moment to recover from her emotional moment.

"Can we get dressed now?"

"Uh-huh."

He found himself glancing at her again as they dried themselves, watching the way her hair spiked up immediately beneath her towel, the way her eyes narrowed as she concentrated, her eyebrows sinking low until her forehead creased in between.

"You're cute," he explained, when she looked up at him questioningly. "I mean, of course you are, you look like me. But still, it's weird."

"I'm weird?"

"No, it's weird that I think you're cute. I don't even like kids. But you're... Well I guess it's genetics or some shit, I just like you even though I don't like kids."

"I like you too, Daddy!"

He unzipped the hoodie Hisami had picked out and held it open, letting her slide her arms into the baggy sleeves. After a moment of contemplation he grabbed a scarf from his clean laundry, grateful for once that he'd managed to get his winter gear muddy during his morning run. Rather than zip the hoodie up, he pulled one side of it right across her body, then layered the other side over top, securing it with his scarf as a belt.

"Daddy is a genius!" she grinned, when Katsuki looked proudly at his handiwork. "I feel like a festival!"

"A festival?" he frowned. "The hell does that mean?"

"The pretty flower dresses!"

"Oh, like a yukata?"

"Yeah!"

"Okay," he snorted, ruffling her damp hair. "I'm glad. Now, what do we do with this, huh? Brush it or some shit?"

"Comb for wet! But I don't have my comb."

"Maybe one of the girls will have one you can use. Let's go see, yeah? Then we can finally have dinner, my bag of groceries is still sitting on the counter."

"Spicy food?"

"You like spicy food?"

"Yeah! Papa keeps saying I shouldn't eat the super spicy stuff but it's always good!"

"Alright, we can have spicy stuff then."

When she reached for his hand, he let her link them together, leading the way back out to the common area where his classmates were watching TV. A few more had gathered, but the gossip clearly preceded them, since no one seemed surprised to see the little girl in her makeshift hoodie-dress.

"Auntie Mina!" she smiled brightly, when the pink face turned to look at them. She even dropped Katsuki's hand to step forward. "Hi!"

"Hi, sweetie!" Mina beamed, jumping up from her seat and accepting Hisami's hug. "Did you have a good bath?"

"Uh-huh! It was so big I got to swim!"

"That's awesome! It's a really nice bath, right?"

"Uh-huh! And Daddy made me a yukata 'cause my clothes got broke."

"He's very clever, isn't he? You look nice and warm and cozy!"

"And it's my favourite colour!" she grinned, tugging at the fabric like maybe Mina hadn't seen it. "It's so pretty!"

"Red is a nice colour, it looks very good on you!"

"Like my eyes!"

"Exactly!"

Hisami didn't even seem to notice that Mina was a decade younger than she was used to, they just chatted away happily as if they'd known each other forever. Katsuki was quietly relieved to see her talk to someone other than him without pouting and shrinking away, but a tiny part of him inexplicably felt a little jealous, too.

"And so now we're gonna make a spicy dinner! Oh, but I gotta find a comb first 'cause my hair is a mess but Daddy doesn't have one. Do you know where I can get one?"

"I'll go get you one, hun," she smiled fondly. "You and Daddy go start cooking, I'll bring one down for you."

"Thank you very much!"

She headed off to her room, and Hisami skipped back to Katsuki's side, taking his hand again happily.

"Food time, Daddy?"

"Yeah, let's go cook."

He dragged a chair up to the counter for her to stand on, setting her up with a sink of water and a bunch of vegetables to clean while he began heating and chopping. She hummed to herself as she cleaned, just the way she had in the shower, and something about it was so oddly familiar but he couldn't quite put his finger on it.

"All done!" she said proudly, handing him a bowl of freshly washed vegetables. "What next, Daddy?"

"Gimme one second and I'll find you your next job."

"Kay!"

"How about I help you with your hair while you wait?" Mina asked from the hallway. "Let Daddy do the cutting and you can help after?"

"Yeah!"

Mina sat down on the carpet, waving her over, and Hisami dropped into her lap like it was no big deal. Katsuki could see the fawning squeaks desperate to come out of Mina's mouth, but she held them back valiantly, settling for giving Hisami a little hug.

"Do you want to wear it loose or shall I tie it up for you?" Mina asked, as she gently ran the comb through Hisami's spikes. "Does Daddy usually do your hair in the morning?"

"Uh-huh! He's super good at bows!" Hisami nodded. "And sometimes he even does braids for me!"

"Yeah, Daddy is good at just about everything, isn't he?"

"Everything except saying please!" Hisami giggled.

Katsuki rolled his eyes when Mina burst out laughing, forced to take a moment to compose herself.

"He hasn't changed at all, huh?"

Hisami turned her head, looking at Katsuki at the counter, and shook her head when their eyes met.

"Nuh-uh! Except his hair."

"Oh yeah? What happened to his hair?"

"This Daddy's hair is big and fluffy! Normal Daddy's hair is short!"

"Ahhh, so Blasty finally gets a haircut one day? Good, I'm glad."

"Do you know how to do the twisty thingy with hair?" Hisami asked. "Like the half? Gramma does it for me sometimes!"

"Can you show me what you mean?"

She picked up the sides of her hair, twisting them messily back behind her head, and to Katsuki's disbelief, Mina nodded.

"I think I know the one! With a bow in the back?"

"Yeah!"

"Do you have a ribbon or should I find you one?"

Katsuki pulled two bright red strips from his pocket, still slightly damp from the shower, and Mina smiled, shaking her head when he offered them to her.

"You said Daddy does the best bows, right? How about I just do it with an elastic and he can do your bow for you?"

"Yeah!"

Katsuki rolled his eyes, but didn't protest. He continued cooking while the pair worked, only looking up again when Hisami sidled up to him and took the ribbons from his pocket.

"You look very pretty," he told her, as he washed his hands. "Okay, turn around I guess."

She pushed the ribbons into his hand and turned, smiling to herself as she waited. Katsuki frowned as he contemplated, threading both strands around the thin elastic band and wrapping them a couple of times to cover it. That seemed like a good step one.

With that done, he tied them in a knot to secure them, making sure both sides were even for the loops. The most he'd ever tied before was a shoelace, so ribbons felt beyond him, but his daughter seemed to believe in him and he was stubborn enough to make it work.

He made two careful loops, knotting them together and checking again that they were even before he secured them in place. He fanned out the two ribbons, making the bow a little bigger to look at, then pulled out his phone to take a photo.

"Look okay?" he asked, holding it out to show her the screen. "Is it too messy?"

"It's perfect!" she beamed, turning around to hug him tightly. "Thank you Daddy!"

"You're welcome, Pipsqueak. You ready to eat? We're just about finished here."

"Yeah!"

Mina excused herself with a smile, leaving the pair to dish out their food and sit down together at the table. Hisami sat on her knees to reach, but she didn't seem concerned by it, so Katsuki didn't bother to address it.

"Tastes yummy!" she praised, when she took her first bite. "Thank you!"

"You must have done good washing," Katsuki smirked. "Good job."

"Teamwork!"

"Precisely."

Katsuki was pleased to find that Hisami was a quiet eater, much like himself. Neither of them bothered to make conversation, too busy with their bowls of food, only exchanging the occasional little smiles when they caught each other looking.

The peace ended, though, when they finished eating and headed back out to the living room, only to find even more people hanging around, and a familiar freckled face just coming in the front door after his weekly dinner with All Might.

"Papa!" Hisami yelled, leaping at him with zero hesitation. "You're here! I missed you!"

Izuku stared with wide eyes when Hisami dove into his arms, catching her obediently and letting her nuzzle against his neck and cheek.

"What the fuck," Katsuki muttered. "Hisami, what are you doing?"

"Papa is here, Daddy! Look!"

Pieces slowly began to fall into place in his mind, his cheeks burning bright red as he slotted them together. Hisami hadn't just been using two different father titles, she had two fathers. And apparently the second was...?

"I got lost, Papa, but Daddy found me and brought me here and I dunno where we are but I'm so happy you're here too! Where were you before? Working? Did you have patrols again? Daddy seemed lonely without you but he didn't say anything so maybe he was trying to pretend he was okay for me since we're in an unfamiliar place but I'm okay! I'm big and brave! I can take care of Daddy and Papa in the weird home!"

"God damn it you just had to learn to mutter like him didn't you?"

"You say that every day, Daddy."

Izuku still seemed like a deer in headlights, gaze darting between Hisami in his arms with her bright smile, his classmates looking on in varying states of shock and awe, and Katsuki, cringing harder than ever before, pointedly avoiding every other pair of eyes in the room.

"H-Hey, Pipsqueak," he choked out in a hurry. "Um, he doesn't know you yet, remember? Like me."

"Oh," her smiled faded a little, and she looked up into the emerald eyes, seeing the confusion and concern waiting for her. "S-Sorry. I, um..."

She bit at her lower lip, but Izuku just smiled, shaking his head faintly.

"It's okay," he assured her, hugging her gently. "Did you think I was someone else?"

"N-No, you're my... Well, you will be my Papa, but I guess... I guess not yet."

"I'm sorry sweetie, I didn't mean to make you sad."

Katsuki plucked her gently from his arms, stroking her back when he saw her sullen face, her eyes shining a little with tears that she would never allow to fall.

"Hey, you don't need to be upset," he assured her.

"I'm not," she said stubbornly, cheeks puffing out a little in her indignance. "I just forgot."

"Why don't you introduce yourself to him, like you did to the rest of us, yeah? Maybe you can explain why you got excited, for him?"

She nodded firmly, wiping a stubborn tear from her eye as she looked up at Izuku's sweet smile.

"My name is Bakugou Hisami," she explained, just like she had to a crowd of their friends. "I'm three years old and Bakugou Katsuki is my Daddy and Bakugou Izuku is my Papa! Oh. Um, maybe you're not that yet? M-Midori?"

"Midoriya," Izuku nodded. "Midoriya Izuku, that's my name."

"Yeah! Like Gramma! Midoriya Izuku is my Papa, except his name- your name- changes before you have me! And, um, Daddy gave his genes to a lady and she cooked them up to make me for you both! And you named me Hisami from you both!" She drew the characters in the air proudly, spelling out her name. "Hisa like you and the Grampy I never met, and Mi like Daddy and Nana!"

"Are you serious, Hisami?" Katsuki asked, his mouth strangely dry. "Are you making a joke? You're very good, if you are."

"Nuh-uh! Papa didn't want to use his genes because of- Oh. I can't say- Um. Oh! Because of my booms!"

"Your booms?"

"Yeah!" Hisami grinned, clapping her hands and shooting off the tiniest, sparkliest explosions. "Papa wanted me to have booms like Daddy! So he used Daddy's genes for me! And Daddy says I probably got lots of bad stuff from him but Papa says I'm one hundred percent perfect just like Daddy!"

It was Izuku's turn to blush, at that, and Katsuki managed the tiniest of smirks.

"I'm perfect, am I, Deku?" he teased.

"Maybe in the future," Izuku snorted. "When you grow up a little."

"Wow, asshole."

"Does Papa believe me?" Hisami asked quietly, lower lip jutting out. "I missed you."

"Of course I believe you, sweetie," Izuku assured her, holding out his arms. "Come give me a hug."

Katsuki handed her over, and Hisami finally let her tears spill over as she snuggled into him, hiding them in his shoulder quickly. Izuku smiled as he patted her back gently, humming a familiar tune.

When Katsuki heard the hushed arguments behind him, he turned to see an intense debate raging between his classmates, held entirely in harsh whispers.

"Do you know how long we were together before we had you?" Katsuki asked, watching Hisami peek up from the grey blazer to look at him. "Are we... Shit. Married?"

"Uh-huh," she nodded, wiping her eye on her baggy sleeve. "Gramma cries when she looks at the photos 'cause you both look so pretty and happy."

"God damn it," Katsuki muttered, when he heard his friends cooing behind them. "Shit, let's uh, let's go up to my room to talk about this."

"Why? 'Cause Uncle Pikachu and Uncle Eiji will tease you again?"

"Exactly," Katsuki blushed, amidst much louder laughter from the group. "Come on, Pipsqueak."

Izuku followed him with an apologetic smile shot back to the group, Hisami still snuggled into his chest and shoulder. She was whispering something incomprehensible against his shirt, but he didn't bother to ask – she was Katsuki's daughter, after all. If she wanted to be heard, she would make herself heard.

"Hisami," Katsuki began, when they were safely locked inside his room. "I'm gonna be real honest with you, okay?"

"Uh-huh."

"Me and Deku aren't, like... together. We're just friends, and that's all. So we're, um, kind of surprised by all this shit."

"Mm-hm," she nodded, wiping her eyes once more, but this time they seemed to stay dry. "Daddy and Papa didn't get married until they were both top ten heroes."

"Are you serious?" Katsuki snorted, while Izuku giggled into his hand. "On purpose?"

"Uh-huh. Rankings before Wedding Rings."

"That sounds like a shitty Deku slogan if I ever heard one."

"Hey," Izuku laughed, punching him lightly with his free hand, the other still holding Hisami up. "Don't be mean in front of our daughter."

Katsuki blushed bright red again at the word, staring pathetically at the tiny girl with her blonde hair and red eyes and the sparks hidden in her palms.

"Do you know how long we were together before we got married?"

"Mm-hm. You had your ten year anniversary a little after Papa's birthday."

"And do you know how old he turned, Pipsqueak?"

"Twenty-seven. I got to help Papa count the candles."

Katsuki swallowed hard.

"I turned seventeen last week," Izuku smiled softly. "Do you think maybe we got together because of this? Because of you?"

"Daddy says he loved you forever and ever. Since you were just little like me."

"I've loved Kacchan since we were little, too," Izuku smiled, before Katsuki had a chance to squawk indignantly about it. "I guess maybe I should take him on a date, don't you think?"

"Yeah! Daddy gets embarrassed when you go on dates, but he always comes home super happy! And I get to watch Princess movies with Uncle Pikachu or eat pizza with Auntie Mina and Uncle Eiji!"

"At least we know we both live to twenty-seven," Katsuki snorted, hiding his blush behind a hand futilely. "That's not an excuse to do stupid shit and assume you're invincible though, nerd. Don't even think about it."

"I would never!"

Izuku finally sat down on the bed at Katsuki's side, letting Hisami fumble for his hand to hold so she could be linked with them both.

"What's the matter, baby?" Izuku asked softly, when the tears began to flow again. "Is everything okay?"

"I miss my other Papa and Daddy," she sniffled, hiccuping a little as she held back her sobs. "I'm sorry."

"You don't need to be sorry," Katsuki assured her, squeezing her hand a little tighter. "We understand. I'm sorry we don't know all the things you know."

"It's probably your bedtime, too," Izuku smiled faintly. "I bet you're over-tired."

"You want to go to bed?" Katsuki picked up for him. "Aizawa-sensei is gonna figure it all out super soon so that we can get you home."

"M'sleepy," she agreed. "B-but I don't wanna go."

"Go where, hun?"

"T-To bed. Wanna s-stay."

"You don't have to go anywhere," Katsuki assured her. "It's about my bedtime too, I'll stay here and sleep with you. Do you wanna sleep in my bed?"

She nodded firmly, and Midoriya plucked at her little hoodie-dress.

"I know someone who can make you some clothes," he informed her. "I'm gonna go get you some nice warm pyjamas to wear, and some clothes for tomorrow. What kind of clothes do you like best?"

"The dresses Nana brings me from work."

"Ah-ha, pretty things with bows and ribbons and ruffles?"

"Uh-huh. I like bows. See my bow?"

She pointed at her hair, and Izuku nodded, humming his approval.

"Super pretty. Okay, you give Kacchan cuddles and get ready for bed. He probably has a spare toothbrush you can use. I'm gonna go visit my friend and I'll be right back, okay?"

"Thank you Papa."

"Any time, sweetheart."

He showed himself out, closing the door behind him, and Katsuki pulled Hisami into his lap.

"I promise we'll get you home, Pipsqueak. Me and Deku are probably freaking out about you being gone, every hero in the city will be out searching for you."

"Papa was there when I left," she mumbled, leaning into him and closing her eyes. "He saw the lady send me away."

"He's probably talking to her right now, then, figuring out how to bring you back. It won't take long."

"What if I can't, Daddy? What if I can't go back?"

"Then you'll stay with me," he said firmly. "My parents – uh, you said Nana, right?"

"Nana and Pop," she agreed. "Um, M-Mitsuki and Masaru?"

"Yeah, good memory. Nana and Pop will help look after you while I'm at school, I'm sure Gramma Inko will help us out too. And you can teach us all the things you do, the things you like, and we'll all learn how to do them for you. I promise you'll be super happy, even if you have to stay a while."

"Or forever?"

"Or forever," he agreed. "But it won't be forever, because me and Deku will never ever give up on getting you back. And the best part of time travel is that even if it takes us years to figure it out, we can still come back to right now and get you, we won't have to wait years and years."

"Okay," she agreed. "I don't mind staying here with you until then."

"Good. I'll do my best to be a good Dad."

He rolled onto his back, dragging her with him so she lay across his torso, and she smiled down at him before she snuggled in.

"You're already the best Dad."

When Izuku returned, clothes in hand and his own outfit changed to match, he found them in that same position, cuddled together on the bedsheets. They both blinked their eyes open to look when he opened the door, and he held up a pair of bright red pyjamas with a smile.

"To match your bow!" he explained. "You like red, right?"

"It's my favourite!"

"Good! And the girls had fun coming up with cute outfits for you, so I've got a couple of things here for the morning, so you can choose." He gestured with the pile balanced in his arm, setting them down on top of Katsuki's dresser. "Do you need help with your pyjamas?"

"Uh-huh."

Katsuki watched through tired eyes as Izuku helped her change her clothes, smiling and laughing together the whole way through, then with a little kiss on his cheek that he happily returned, Hisami rolled over to snuggle with Katsuki again.

"Is Papa gonna stay too?" she pouted, reaching a hand toward him.

"Yeah, Papa," Katsuki snorted into his pillow. "You gonna stay for cuddles?"

"If Daddy will let me."

The teasing tone made Katsuki blush again, immediately regretting ever starting the game, but his worries were quickly forgotten when another weight sank into the mattress. Izuku lay down nervously, waiting for Katsuki to send him away, but Katsuki just rolled over a little closer to the wall and made room for all three of them.

"Are you happy, Papa?"

"Of course I am!" Izuku assured her. "Why did you ask?"

"Your happy lines are gone," she mumbled, reaching out to touch his face, fingers running up and down the side of his eye.

"Shitty nerd has wrinkles," Katsuki snorted. "You're not even thirty yet and you have wrinkles!"

"Shut up!" Izuku pouted. "Just because you have your mother's eternal youth thing going on doesn't mean you get to be a jerk."

"Happy lines!" Hisami said again. "Daddy likes your happy lines."

"Hear that, Kacchan?" Izuku poked his tongue out childishly. "You like them!"

"Yeah, yeah, whatever," he scoffed. "Can we sleep now?"

"M'sleepy too, Daddy."

"Good. I know we normally read a story, but I think we're both pretty tired, yeah? Do you mind if we don't read tonight?"

"I'll tell you a story," Izuku offered, when Hisami hummed thoughtfully. "It won't be a reading story, I'll just tell it while you snuggle up to sleep, yeah?"

"Yeah!"

He joined them under the blankets, draping his arm across both their tired bodies, and smiled to himself as he curled in with them.

"Once upon a time there was a little boy with no quirk, and his best friend had the most amazing quirk in the world."

"This one is my favourite," Hisami said sleepily, yawning as she nestled in. "Don't forget the bit with the sludge villain, Papa."

"I wouldn't dream of it."


Katsuki woke to a calm knock on his door, wondering briefly if he'd overslept until he saw the pitch black of his surroundings. He had two bodies draped over himself, one a lot heavier than the other, and he groaned as he attempted to lever them off.

Another knock.

"Who is it?" he called groggily, shaking the nerd awake. "It's the middle of the damn night."

"Sorry to wake you!" a strangely familiar voice spoke through the door. "I just came to pick up Hisami, Aizawa-sensei told me she was here!"

The little girl finally woke up at the sound of her name, sitting up and rubbing at her eyes sleepily.

"I asked who you were, asshole," he repeated, as Izuku looked around in confusion. "I'm not unlocking the damn door if you can't even answer a simple question."

"Sorry, Kacchan!" the voice chuckled. "It's Izuku! Bakugou Izuku!"

Hisami leapt up when she heard the voice, suddenly wide awake as she fumbled with the door handle, whining when Izuku pulled her away gently. Katsuki flicked the light on, giving them all a moment to adjust before he slowly opened the door.

"Sorry to wake you! Unfortunately time travel is only so controllable."

"Papa?" Hisami asked, blinking up at the tall, freckled man, before her face broke into a smile. "Papa! It's you! The real Papa!"

"There you are, my little love! I've been looking all over for you!"

The older Izuku scooped her up for a hug, her tiny body dwarfed by his thick arms.

"I got lost," she pouted. "But I found Daddy and he looked after me even though he doesn't know me yet."

"Your Daddy is such a good boy, isn't he?" Izuku teased, eyes shining when he looked down at the awed Katsuki before him. "Thank you for taking care of her. I know this must have been weird for you."

"Whatever," he shrugged, looking away stubbornly. "Like I was ever gonna abandon a kid who looks just like me."

"She does, right? She's the cutest little thing I've ever seen!" He nuzzled at her face playfully, and Hisami giggled and squirmed in return. "Aren't you, baby girl?"

"Pretty like Daddy!" she agreed with a grin. "I missed you, Papa!"

"I missed you too. So, so much! I didn't sleep last night, I was too busy coming to find you!"

"I slept with Little Daddy and Little Papa. They kept me safe!"

"I'm so glad."

The younger Izuku finally stopped mumbling for long enough to look up, meeting a matching pair of green eyes in a much older, less chubby-cheeked face.

"Do you remember this?"

"This didn't happen to me," he smiled wryly. "It's not direct time travel, more like an alternate timeline. You guys have complete free will, you can make whatever decisions you want."

"So we could just not get together and none of this would happen?"

"Correct. At least from what the quirk holder told me, anyway."

"Good," Katsuki snorted. "Because I promised myself I wouldn't do the parental-name-mash bullshit when I had my own kid."

"We'll see about that," the older Izuku teased. "You want to know all the dirty secrets, Kacchan? Like how you cried like a baby on our wedding day?"

"Shut up."

"And how you refused to put Hisami down for a week when she was born? Just carried her with you constantly even when she was sleeping?"

"Shut up."

Still grinning, Izuku leaned over and pinched at Katsuki's cheek, shaking him lightly.

"You're such a cute little thing, aren't you? Don't you think, Hisami? He's much littler than your Daddy, isn't he?"

"With poofy hair!" Hisami giggled. "It's all fluffy!"

"Yeah, I'd forgotten about the hair!" Izuku ruffled it playfully, amused that Katsuki didn't shove him away. "Don't worry, Kacchan, you're gonna be drop-dead gorgeous as an adult."

"I'm already fuckin' hot."

"Sure you are, babe," Izuku laughed. "The hottest."

"Super hot!" Hisami agreed. "Hot Daddy!"

The younger Izuku had to stifle a laugh when Katsuki burned bright red, watching on fondly as his older self teased with a confidence he wasn't sure he'd ever achieve.

"So how are you gonna get home, anyway?" he spoke up, watching Katsuki breathe a sigh of relief when the hand left his head. "Did you find out how the quirk works?"

"Well, it wears off in like a week, but I have a bit of her quirk stored here that I can use to get back!"

He pulled out a small plastic disk, and immediately Izuku was all over it, examining the little piece of technology.

"They store quirks?!" he marvelled. "How?!"

"You just hit the button then use your quirk, and it'll absorb it. Then when you hit the button again, it'll come out!"

He pulled a second one from his pocket, handing it to Katsuki and getting a little scowl as he accepted it warily.

"My Kacchan set this one up for me. He said 'I know me, I'm gonna ask' and stuffed it in my pocket."

"What is it?"

"Your quirk, dummy. Just push the button, it's not a big one."

Katsuki pushed it obediently, eyes widening when a familiar explosion popped off in his hand, the disk dissolving in his palm. He looked up at the smug little smile that was so inexplicably attractive, then looked away again with a pout.

"Alright, I get it," he grumbled. "Whatever."

"Shall we head back home, little love?" he asked softly, hitching Hisami up higher on his hip. "You wanna say goodbye?"

"Wanna hug."

"Okay."

He set her down, and the other Izuku knelt down beside her, smiling as he stroked her hair.

"It was so nice to meet you, Hisami. Thank you for telling me all those nice stories."

"I love you, Little Papa!"

"I love you too, sweetie." He leaned in close, lips right beside her ear. "I'm gonna make sure Kacchan falls in love with me, so we can meet again."

With a wide smile she turned her head to return the whisper, giggling sweetly.

"Daddy likes it best when you give him cuddles after a long day!" she informed him. "And when you call out 'welcome home, Kacchan!~' and go to him for hugs!"

"Thanks baby, I'll be sure to do that."

She planted a little kiss on his cheek and skipped over to Katsuki, snuggling into his warm chest and savouring the arms that wound around her.

"You'll always be my Daddy," she said softly. "Thank you for being such a good Daddy."

"I love you, Pipsqueak," he whispered back, hiding his watery eyes in her hair. "You be good, okay? Be good for Daddy and Papa. Be safe, and be healthy, and be happy, and don't answer back when Daddy tells you to clean your room."

"I promise!"

He hugged her tight one last time, returning the little kiss she gave him like it was the most natural thing in the world, then finally she returned to her own Izuku, the much taller, more muscular version, with his broad shoulders and strong jawline.

"Take care of her, nerd," he insisted, swallowing hard. "If you don't, I'm gonna travel every damn timeline until I find you to punch you in the face."

"I will, I promise," he laughed. "You be a good boyfriend."

"I'll be the best damn boyfriend ever, and you know it."

Waving, Hisami hit the button on the disk, and before their very eyes the pair melted away into nothing. Izuku's arms were out immediately, pulling Katsuki into his grip, and for once Katsuki didn't even pretend to protest.

"It'll happen," Izuku smiled softly, pressing their cheeks together as they hugged. "We're gonna get through school, take down all these shitty villains, become the best heroes in the world, and when all that is done, and our world is safe, we'll find the right surrogate and have a baby of our own."

"Our baby might not be Hisami," he mumbled, sniffling a little.

"No, but we'll love them all the same. We can always keep trying. Eventually it's bound to work."

Katsuki turned his head slowly, but the nerd was one step ahead as always, capturing his lips the moment they were close enough. His fingers tightened into Izuku's shirt, dragging him ever closer as they kissed, and finally with a little smile Izuku pulled away.

"Shall we go back to bed, Kacchan?"

He didn't bother to dignify it with a response, simply falling back onto the mattress and glancing at the glowing numbers on his bedside table. There was still at least an hour until sunrise, when he would normally get up to work out, but today... Today maybe he'd give himself a break.

Izuku snuggled in immediately, draping himself across Katsuki's chest and listening to his heart pound.

"From today onward," he said faintly. "We'll be together forever, okay?"

"Someone is demanding," Katsuki smirked, raking his fingers through Izuku's curls. "Only if you do your best to look like that."

"You thought I was hot?"

"I thought he was hot."

"But he's me!"

"We'll see," Katsuki snorted, amused when Izuku shot him an offended look. "He said it might not turn out the same, yeah? And I can't ever imagine your lazy, freckled ass becoming a beefcake."

"I will," Izuku pouted, his cheeks puffing out in the exact same way Hisami's had only a few hours prior, when the pair first met. "I'm gonna be hot as fuck. You won't be able to dream of resisting my charms."

"Good."

His expression softened a little, with Katsuki smirking down at him, his hand still gently petting Izuku's hair.

"On one condition."

"What's that, nerd?"

"You really need a haircut."
