Chapter 1: Boys are stupid

Notes:

Thanks to my friend and fellow writer Hi_H3llo_owo for beta reading this!

Chapter Text

Kyouka lays face down into a pillow and groans.

“Boys are so stupid!!!” her exclamation of agony is muffled by the fabric of the pillow case.

Katsuki stares at her, slightly annoyed by her intrusion. He moves onto his bed, and rolls her over to face him. “Why the hell are you in my room?”

She pouts, cheeks puffing out slightly. “Did you not hear me? I said boys are stupid!” The ash-blonde rolls his eyes and scowls.

“Then why are you in MY room? Can’t Ponytail talk with you or something?”

“Because YOU have a boyfriend!” she sits up and points to him. Her hand drops and she looks away, cheeks blooming a soft scarlet color. “P-plus you’re the only one who knows about...well you know.”

“Your crush on Sparky?”

“I-It’s not a crush!!” She defends, jabbing him in the arm weakly with her earphone jack. She grumbles, obviously frustrated about her feelings. She ponders as to what she’ll say next, face shifting to a richer shade of red. She purses her lips and looks at Katsuki with a timid gaze. “...H-how did you do it?”

“Hah?”

“How did you get Kirishima to notice you? Like… In a non-friend way.” She taps the tips of her jacks together nervously. She looks away, her body becoming rigid with anxiety. “A-actually never mind. I’ll just go.”

Katsuki sighs, “Stay. You’re a damn mess and you clearly need help.” Kyouka looks at him, a slight pout gracing her lips. The blonde looks at her, his expression softening.

“Look, I didn’t do anything. I mean he was the one that confessed, and I just so happened to reciprocate.” Kyouka looks down, somewhat disappointed at his response.

Katsuki purses his lips into a thin line. He shifts himself closer and puts a hand on her tense shoulder. “Did something happen to make you frustrated?”

She looks at him, and nods in reply to his question, “He keeps flirting with other girls, but he doesn’t even bother to look at me that way,” Katsuki hums and she looks at her hands. “But sometimes he’ll say these things that make my stomach flip, and I can’t tell if he’s only being nice to me.”

The blonde pulled the purple-haired girl closer to rest on his shoulder, like his mother did to him as he went through this. “Jirou, Sparky is an idiot.”

“Well we both knew that.”

“Yeah, and he is an absolute coward when it comes his feelings.” Kyouka looks at him slightly confused, “He likes you, but is too damn scared to tell you.”

“He likes me?” the girl mutters unbelievingly under her breath, “but how do you-”

“He never shuts up about you, he straight up asked me if I could move so he could sit next to you.” The aggressive boy explained. He continued to rattle off on how Denki Kaminari had obvious feelings for the punk rock girl.

Kyouka pauses, and thinks. A slight blush creeps across her cheeks and ears. “Oh my god…”

“Yep.”

“H-he likes me back!?”

“There it is.”

“What do I do now?“ Katsuki looks at her, a slight smile adorning his face.

“You tell him obviously,” He states matter of factly.

“I’m bad at talking to him and he’s dense as hell!” She pouts, a slight whine in her tone.

“I know he's a dumbass, Jirou. Just kiss him or something… but not too much. No tongue.” Kyouka giggles and looks at him teasingly, mischief ringing in her voice.

“Why not~?” She nudges him and he tenses up.”

“Because I said so! Don’t shove your tongue down his throat or-”

“Or what, Bakugou?” She smirks and watches the blonde’s face contort into one of anger.

“Because, you’re too little to be doing that! Now shut up about it, you’re pissing me off!” The short haired girl bursts with laughter, clutching her stomach as she wheezes. “Shut the hell up! It isn’t funny!” She calms down, and looks at him, violet eyes gleaming in the light from the window.

“Sorry, hehe, um,” She tucks her hair behind her ear and smiles, “Thank you for making me feel better.” She hugs him hesitantly, making Katsuki blink.

He hugs her back, and moves away quickly. “Tch. Can you leave now?” she nods and stands up, waving goodbye as leaves his room.

Katsuki sighs and lays back on his bed, smiling a little to himself. His moment of peace was interrupted by a knock at the door.

His boyfriend entered the room, his soft features traced in golden light from the window. The redheaded boy plops on top of him with a signature grin on his face. Their fingers intertwine and a chaste kiss is shared between the two.

“Katsuki, should I be worried that you’re cheating on me with Jirou?” Eijirou asks jokingly, a laugh following his remark.

“What? Ew, no she’s like my sister.” The other boy giggles, then plants a kiss on his cheek.

“I know, I’m just teasing. She likes Kaminari anyways.” Katsuki hums and lays his head back.

“I just hope she’ll finally tell him so she can stop pestering me all the damn time.”

“Accept it Katsuki, you like it when she comes over to talk to you,” Eijirou teased, his playful smirk still lingering on his lips. Katsuki looks away and scoffs.

Although he’d never admit it, he really did like it when she came over to talk.

Chapter 2: The Question He Asked Every Sleepover

Summary:

Kyouka and Katsuki have a sleepover. Flustered Katsuki is a thing.

Notes:

This is just a short little origin story for the title basically. My head canon is Katsuki really wants a niece because...well I might write about the reason he wants a niece another time. So yeah, this is also here to show off how close their relationship really is for example they'll call each other by their first names. I hope you like this short thing.

(See the end of the chapter for more notes.)

Chapter Text

“Katsuki, I said no.”

“Please.”

“you ask me this every time I sleepover at one point or another, and my answer is always the same, no”

The aggressive blonde whines, braiding her hair tighter. She yelps, and he loosens the strands of hair slightly. “Why not!?! I asked nicely!” Kyouka rolls her eyes and continues to paint her nails.

“You know. I find it ironic that you were the one that told me no sleeping with him, and now you want me to have a-”

“KyOukA, I WaNt A nIeCe!” She laughs at his silly comment, turning around on her spot on the floor to look at the pouting boy. She grabs his cheeks, careful not to get nail polish on him, and looks him in the eyes.

“Katsuki, we’re still in school. At least wait until after we graduate.” He swats her away and scoffs. He grumbles, muttering something under his breath. “What’d you say?”

“I said fine! Just...don’t wait too long after.” Kyouka tilts her head in confusion.

“Why do you want a niece from me so badly anyways? I’m sure Mina would be totally fine giving you like three.” He rolls his eyes and shakes his head.

“You don’t get it. You are the only female on this whole damn campus I can tolerate. Unlike literally everyone else you kind of understand my emotions I guess.” He pauses to think, a slight flustered blush tinting his ears and neck. “And I mean you even helped me with my crush on Eijirou.” He smiles softly looking down at his hands.

“...I don’t know, I guess I kinda see you as family away from my family.” Kyouka smiles genuinely, touched by his words. His face shifts to a red hue, and he pouts in embarrassment. “I-if you tell anyone I said this y-you’re dead meat, headphones!” She bursts with laughter, doubling over in her spot on the floor.

Katsuki grumbles, and she wipes fake tears from her eyes. “Thank you...I really mean it.” She pulls him into a loving embrace, giving him a crooked smile. “I’m glad it isn’t just because we’ve known each other for years. If one day I find out I’m having a baby girl. You’ll be one of the first to know.”

“One of the first? I’m first.”

“No, I should be the first.”

“Okay fair enough, second then.”

“No, because the father should know second.”

He groans, pinching the bridge of his nose. “Third? Can I at least be the third?!”

“...Deal.”

Katsuki smiles a bit and hums, tying off the hair he was braiding earlier. He crawls over to his lamp and turns out the light. “Alright, enough talking, get in your sleeping bag. I’m tired.”

Kyouka giggles and nods, “yes, sir.” she crawls into the warmth of her sleeping bag and her eyes begin to flutter closed. “Night, Katsuki.”

He smiles and gets under the covers. He whispers softly back to her before he dozes off. “Goodnight, Kyouka.” The room fills with a peaceful silence and they both slowly drift off to sleep.

Notes:

I hope you guys liked this short little origin thing. My friend Hi_H3llo_owo (who graciously beta read this for me) and I have this head canon where Katsuki has a soft spot for little kids but I'll touch on that in another one shot. If you could not tell this takes place a few years later so this whole series of one shots will just kind of hop around time wise. Anyways hope you enjoyed it, feedback is very welcome, and have a nice day.

Chapter 3: This is Why You're Not Allowed To Watch Makeup Videos

Summary:

Kyouka does her makeup and Katsuki comes to help her.

Notes:

Much like Jenna Marbles once said, I was feeling ~generally unmotivated~. I wrote two other one shots before this and I hated one of them, and the other I was worried no one would like. SO I wrote this. I had a lot of fun making this chapter so I hope you all like it!

(See the end of the chapter for more notes.)

Chapter Text

Kyouka lays down on her bed, earphone jack plugged into her phone as she watches mindless videos on the internet. A video comes up in her recommendations and she’s immediately intrigued. She frantically gets up and grabs her small bag of makeup, sitting by her mirror.

After hours of immense failure she decides to call in backup.

“Bakugou!! Help!”

“What happened? Do you need help with reaching something?”

“Now is not the time to make fun of me you ass!!” She rolls her eyes when she hears his snickering over the phone. “Seriously, just help me Kats. Please.”

He audibly sighs, and groans. “Finneeeeeeee I’ll be there in like a couple minutes.”

As he said, there was a knock on her door minutes later. Kyouka opens the door, letting the explosive boy in. He takes a seat on her bed, crossing his arms.

“Okay what do yo- Holy- What the hell did you do to your face!?” He exclaims with a dramatic grimace gracing his features.

Foundation blended unevenly, eyeliner transferring onto her eyelids in large black splotches, and lipstick staining her teeth it fairly obvious what she had been up to. “I tried to do my makeup.”

“Emphasis on the word ‘tried’.” The blonde said, pinching the bridge of his nose. “How did you even fuck yourself up this badly? I’m genuinely shocked, there’s lipstick in your hair!!”

“I know, I know it looks bad. I just wanted to try something different and I failed.”

“You need help.”

“THAT’S WHY I CALLED YOU IN HERE!!” She yells with a childish pout. She tugs at his arm, pulling him off the bed almost making him stumble forward. “Come on, can you help me fix this? I have plans tonight.” Katsuki looks away as she pleads, wincing as he feels his resolve crack. He sighs and rolls his eyes.

“Alright, but you better not whine if you don’t like what I do.” The bright smile that blooms on her face assures she’s okay with his terms. She sits down in her bed, grabbing her makeup bag for him to look through. Skimming through the products, Katsuki looks at her slightly surprised.

“What?”

“You have like four things in here.”

“Well.. yeah. I don’t like makeup that much. I only ever wear it when I need to hide my acne, or when I go to nice places.” Katsuki hums, filtering through her bag once again.

“I’m guessing you’re going somewhere?”

“Denki’s house.”

The blonde rolls his eyes and grabs what he needs. “What’s so important about him now that requires you to wear makeup now?”

“I’m uh.. meeting his parents for the first time. I want to make a good impression on them.”

“Why?”

“Because I really like him, and I want his parents to like me so I can keep dating their son.” A flick to her forehead makes her cringe in pain, she furrows her brows at yells at the offender. “Ow that hurt you dick! Why’d you do that?”

“If Sparky’s parents are anything like him, then they’ll like you. Plus you, unlike all of the other idiots, have manners so you’ll be fine.” His words make Kyouka ponder, her nervousness setting in. She chews at her bottom lip and looks up at Katsuki. He sighs and prepares to explain. “Look, they’ll like you okay. No need to wear all this fancy shit to appeal to his parents. You look pretty the way you look now, but if you just want to be dolled up for the hell of it then I’ll do it. Just don’t underestimate yourself.”

She smiles softly at his kind words and picks up an eyeshadow brush. “If you don’t mind, I kinda wanna try getting all dressed up.” With the brush being plucked from her hand, Katsuki gets to work on cleaning her up. Once she is once again a clean slate the makeup begins to be used.

“Keep your eye closed I’m gonna put on eyeliner.”

“Ehhh, just don’t get it in my eye.”

“I won’t, I’m not stupid.” The cold black liquid liner touching her skin makes her shiver. The small brush to the product gliding across the pale surface, creating a slight wing tracing her eye. Katsuki repeats the process on the other eye and tells her to open her eyes.

“Do I look okay?”

“Mhm,” In a small compact he picks up some of the pink powder inside, blushing her cheeks with it. The feather light touch tickling her nose making her sneeze.

She sniffs, and apologizes. “Sorry, it tickles.” A mischievous look shines in Katsuki’s eyes. He cleans off the brush and dusts it across her face, making them both laugh. “Haha! B-Bakugou! St-haha-stop!” With obvious reluctance, Katsuki stops his onslaught of tickling. She takes long steady breaths and giggles.

 

He grabs a dark violet shade of lipstick and applies it to her lips. He fixes her hair a bit, pinning back some of her short purple locks. He gives her one last good look before he gives an approving nod and puts away the products he used. “There, you’re done.”

The subtle makeup she wears gives her a pleasant feeling. The slight pink to her cheeks and the purple to her lips making her smile as she stares at her reflection. She twirls an earphone jack around her ear and plays with her hair a little. “Wow, I uh I look nice for once.”

“Shut your face, you always look nice.”

“Not true.”

He rolls his eyes and puts a firm hand on her shoulder. Red eyes locking with violet. “Don’t say that okay. You don’t have to wear makeup to look pretty, or to try and impress someone. You’re pretty the way you are, so don't belittle yourself because you don’t wear makeup.” Her lips purse in a thin line and she nods, looking down at her hands. The shadows cast from the lamp hiding her flattered expression.

“You really need to stop being nice, because It’s beginning to make me think you actually care about me.” The girl’s snarky remark stuns Katsuki, his soft expression quickly shifting to one of annoyance.

“JIROU!! I was tryin’ to be considerate you ungrateful little fu-” A faint knock at the door stops him in his tracks. He turns his head to the door to find Denki Kaminari waiting there in all his glory.

Kyouka smiles as she sees her grinning boyfriend, the dim light somehow making his golden eyes shine brighter. He picks her up off the bed and gives her a loving kiss on the cheek as he hugs her from behind. She rolls her eyes and she giggles, making the boys smitten smile grow.

“You look really cute. Well I mean you’re always cute a-and I’m just saying you look uh really nice and um-” An ear-jack to the chest cuts him off and he jolts, electricity flickering around his body.

“You dork.” she jabs, giggling at his awkwardness. He sneaks a kiss to get back at her but is pleasantly surprised when she kisses back. Pulling away with shy smiles, their eyes lock unable to focus on anything else. Especially the angry Bakugou Katsuki who tries to pry them apart.

“Please don’t just kiss.” His request was denied with a middle finger from Kyouka. He fumes, and releases a small explosion from his hand but retaliates when he sees the sparks emitting from Denki’s. “Tch… whatever.”

“Ready to go Kyo?”

“Mhm.” She pulls out of her boyfriend’s embrace and walks out to the hallway, giving Katsuki a pat on the shoulder. “Thank you… For uh, helping me out today.” He looks at her, a soft expression on his face. He gives her a slight nudge and smirks.

“No problem. Now go wow his parents.” She mimics his smirk and grabs her bag, interlocking fingers with Denki. The gesture making him swing their hands back and forth. She waves Katsuki goodbye, and walks off with her boyfriend, laughing their way downstairs.

Notes:

Thanks again to my lovely friend Hi_H3llo_owo for helping with corrections in this one. Both of us are cowriting an au for the Bakusquad, based off the show Chuck! It was Hi_H3llo_owo's idea to post it here. I recommend you check it out if you're interested. Thanks for reading and suffering through my inconsistent uploads. Have a nice day!

Chapter 4: Getting What He Wanted

Summary:

Katsuki finds out some very big news.

Notes:

Okay so this was one of the two abandoned chapters I wrote this past week. This was the one I actually liked, hence why I have posted it. I didn't think anyone would like this one because it's really short and kinda just me wanting to write something fluffy. And for anyone who wonders, no this is not the last one shot. I just want to hop around if that's okay with you guys. I really hope you like this, if not then that's fine by me. Have a nice day.

(See the end of the chapter for more notes.)

Chapter Text

“Kyouka why the hell did you not tell me sooner!??” Katsuki yells as he bursts through the door, hero costume not completely taken off. She sits on the floor, blinking.

“Um, I forgot...you were still third to know though” She responds flatly.

He runs over and plops down on the floor next to her, taking off his mask to his costume. He takes off the rest of his bigger pieces to his costume, getting irritated when some of the accessories won’t come off. He grabs her shoulders and stares her dead in the eyes.“If you’re pranking me you are a sick and twisted jackass.”

She silently looks under a pillow and hands him a pregnancy test with a little smile on her face.

Katsuki loses all air in his lungs in that moment, eyes flicking from the test to Kyouka. He looks at her, eyes glassy and an excited smile on his face. He pulls her in close, squeezing her tightly, planting a light kiss on her forehead.

“Congratulations, you’re gonna be an uncle.” Kyouka says, voice muffled in his chest. Katsuki’s voice audibly wavers, lip quivering as he continues to be on the verge of tears. He pulls away and looks at her belly.

“I-I’m gonna have a lil’ niece.”

She twirls an earphone jack around her finger and purses her lips. She puts a hand on her stomach awkwardly, still new to the fact of the baby growing inside her.

“Well, technically we don’t know yet, It could be a boy.”

“No.”

“Okay then… so um you’re happy?”

“Duh, Kyouka.” He puts a hand on her belly, amazed that he can feel a slight raise. He looks up at her, hand staying put. “How many weeks in are you?”

She puts a finger to her lips and ponders, counting with her fingers occasionally. “Well I found out about after eight weeks in...and then I forgot to tell you since Denki and I went on our trip.. but um, I’m eleven weeks I think?”

“YOU’VE KNOWN FOR THREE WEEKS?!?!” He yelled, looking offended.

“Look, I went on vacation for two and I’ve been throwing up and jet lagged all week. But hey at least I remembered.” Katsuki rolls his eyes, smiling anyways. He lays on the floor and stares at her stomach, wonder in his eyes.

“Hi kid.”

Kyouka smiles cutely, overwhelmed by the precious interaction. She sits up straighter and pulls up her shirt.

“Denki likes talking to it too.” She watches his expression turned to one of pure awe. He pokes her stomach, tickling her slightly making her swat his hand away.

“Kyouka, there’s a bump there.”

“Yeah, around twelve weeks is when showing normally starts.”

“Yeah but like there’s a baby in there, a real one.” She giggles at his little comments. He puts his hand on her belly, and he grins at his new reality.

“Uh hi.” He speaks timidly, looking at the unborn baby softly. “I am your uncle Katsuki, I’m gonna spoil you so much your parents will hate me, we’re gonna be best friends. When you’re born you can help me cook, and I can watch you when your mom and dad have date nights. You have more uncles and aunts, but I’m gonna be your favorite so they don’t matter. I’m really excited to meet you. I hope you look like just like me, even though we’re not technically genetically related.” He looks up at Kyouka and gives her a proud smile. “But if you look just like your mom then that’s okay too, she’s a pretty cool person.”

Kyouka sniffles, covering her smile and teary eyes with her hands. She hears Katsuki giggle and she laughs it off. “I-I’m sorry, my hormones are crazy.” He gives her a hug, and let’s her cry out her feelings. “Do you think I’ll be a good mom?”

“What kind of a shitty question is that? Of course you will. You’ll be the best damn mom on the planet, and I’ll be the best uncle.” Kyouka giggles and wipes her eyes, trying to steady her breathing so she doesn’t hyperventilate.

“I-I’m so glad you’re happy.” She says with a bright joyous grin on her face. The slight light makes her teary eyes look glassy, and she has a soft flush to her cheeks.

“Well duh, I’ve been waiting for this day since our first year of high school, seven years is too long in my opinion.” She laughs and hugs him once more, standing up shortly after and brushing the wrinkles out of her clothes. She tucks her short purple hair behind her ear and begins to stretch out her back, flinching when she hears it pop.

“Hey, wait where are you going?”

She gestures to the kitchen area with her thumb, resting her other hand on her waist. “Sonogram photos. Wanna see em?” His eyes seem to sparkle and he nods, standing upright quickly. He dusts off his hero costume and puts his things by the door haphazardly. Katsuki scrambles his way over to her, and runs a hand through his ash blonde locks.

“Yeah, ‘m right behind ya.”

Notes:

Thoughts? This is supposed to be set after high school and during their hero years. I am genuinely curious if anyone likes the future ones, and if you would like me to write more in the future. Again, feedback is always welcome, I'm always willing to improve.

Also just a random question. Do any of you like the band Marianas Trench? I write a lot of my stuff listening to them and I was honestly curious. If you hate them, that's fine I won't judge you for that. If you love them, same. And if you've never heard of them, I highly recommend.

…Um that's it

Notes:

I don't have an upload schedule, so updates will be whenever they happen. Feel free to leave feed back, I'm pretty new to posting so some tips would be great. Have a nice day!
