[emmyrosee]

hiya emmy :D i was reading ur dad aus, and i thought ‘what if emmy wrote older sibling aus?’ and i wanted to request one :) somehow im a complete softie for ur bakugou, so i wanted to request an older brother bakugou who ten years older than his lil sis, and she absolutely adores him. i think shed be like ‘katsu-nī’ all the time, and be around five? six? when he gets into UA. idk why but im imagining him calling her ‘kid’ or ‘brat(in a nice way, u know?)’ and when hes rlly soft, maybe ‘sweetheart’ when she has nightmares? and maybe when he gets captured, shes so scared that she cant sleep well, and after he comes back, she begs to sleep with him, and mama mitsuki finds her kids sleeping together during the night, with bakugous lil sis clinging to him like her life depends on it and bakugou having an arm around her. and maybe when she was younger, shed enter bakugous room randomly, and sit on his lap while he does hw or study? and shed have all kinds of nicknames for his friends, for instance, she likes to call midoriya ‘zuku-nī’ and kirishima ‘aka-nī’ cuz he had red hair and calls the rest of them by their first names and ‘san’ at the end :) thx for listening to my rant and i hope ur having a good day, and u stay healthy :)

WAIT NO THIS IS ACTUALLY LIKE. REALLY REALLY CUTE-

Because like. Yeah, the last thing the boy needs in his life is a new sibling, he needs that like he needs a UTI.

But then she comes along and he’s like… like he’s obsessed with her.

He tries to hide it under indifference, he doesn’t really care that there’s gonna be a new, tiny presence in his home, he’s got enough to take care of.

That is, until Bakugou Kaida comes into this world.

Until the smallest, sweetest bundle of pink blankets is passed into his arms and it’s then and only then he realizes that he’s doomed, because this kid was going to absolutely have him wrapped around her finger, and come hell or high water, he’d keep her the happiest little brat to walk the face of the earth.

And he is sure to have her grow up with that knowledge.

One time, when she was three, someone pushed her on the playground, and Katsuki nearly punted a four year old- he, instead, told her how to push back (which wasn’t appreciated by his parents) and stand her ground.

However, said ‘happiest brat mantra,’ she knows exactly how to make it curve him for her benefit.

When he’s left to babysit her, she flashes him her biggest set of puppy eyes to make him play with her; his parents have come home god knows how many times to him with a table cloth draped over his back, playing Horsies- she does it more when Midoriya is the horse, because he can’t say no to her either, but anytime she says “Zuku-ni would do it” to Katsuki, he immediately drops on his hands and knees with a snarl on his mouth. Like hell he’s gonna let Midoriya win her heart like that.

And listen, the kid is cute, and she’s got that classic Bakugou charm. She knows how to work it! But Katsuki can’t help the absolute rage down his spine when she’s got her tiny arms curled around Kirishima’s thick neck and they tease him about when they’re gonna get married because yeah, of course, she wants to marry his friends, because why can’t she be disgusted by them like he is?

(”Yeah, bakubro, you’re cool being my best man for it, right?”

“I’d rather skin you alive and drape you over my banister before I let you come near her with a ring pop, do not test me-”)

But obviously, no matter what, for Kaida’s happiness, Katsuki is willing to move boulders, move mountains, part seas, and swallow the stars if it meant she would smile for him.

So, when he gets taken by the LOV, it’s wild how much Kaida deflates. Mitsuki catches her, more times than not, curled up on his bed to sleep for her nap, and at nighttime, she stares longingly outside of her window to wait for him. They try to be gentle and explain that he’ll be back soon, but she doesn’t believe them, she wants to see it with her own eyes.

They put her back to bed, but she’s up a few hours later, perched at her window and whimpering softly. They try to keep her in their bed, but all she does is ask questions about Katsuki until the early hours of the morning, things they don’t always know the answer to.

Those were the longest days of her little life, and when they finally get the call that he’s alright, he’s alive, it’s an extremely tearful reunion. And Katsuki, the hellion and wall of impenetrable rage, screws his eyes shut to fight the stabbing of tears that want to fall into her hair.

Kaida absolutely refuses to let him out of her sight after that.

The entire time they’re talking to the school, her big, crimson eyes are blinking up at him, tiny fingers curled in his shirt collar. Completely unfazed by the snapping between her parents and brother, she just. Stares. She doesn’t smile, she doesn’t frown, she doesn’t pout. It’s just a simple, blank face with all her emotions and relief in her eyes.

Even after the whole ordeal, there’s a part of Kaida that treasures Katsuki (somehow) even more. Anytime he’s home, she’s clinging to him, be it physically by dangling to his back and legs, or simply being in the same room with him: next to him at the dinner table, sleeping on his bed while he’s at his desk, playing with his fingers while he watches tv.

He’d be annoyed by it if she wasn’t so cute.

If he didn’t miss her almost as much as she missed him.

It’s different when he’s away at school and can call her whenever he wants; he hates how much he loves the little snot.

Even now, curled into his side and sucking her thumb while they watch TV, Katsuki knows that if he gets up to merely pee, she’s gonna follow him and sit on the outside of the door, talking to him under the door. (The first time Deku saw that in action, he cooed audibly, and Katsuki nearly ran out of the can with his pants undone to blow him to shit.) and he’d never be able to complain about it.

Sometimes, he can’t help but putting off whatever it is he needs to do, to keep her comfy.

It’s what big brothers do.

“Katsu-ni?” She hums around her thumb. Big eyes look up at him, and he scratched her hair gently.

“What’s up?”

She pauses, as if trying to find the words, her tiny brows furrowed in thought. Then, she speaks, words warbled from the digit in her mouth.

“You think mumma gon’ notice if I go back ta’ school wiff you? In your back-packie?”

He snorts and tightens his arm around her, burrowing his face in her hair to hide the sound. She squeals and bats him away affectionately, completely crawling in his lap when she deems he’s too far from her.

“I think she might, stink.”

Kaida pouts and thunks her head against his chest, the fingers of her free hand fisting his collar. “Do ya have to go…?”

“You know I do,” he grumbles, hooking a lock of hair behind her ear, once again burying his face in her hair. The only noise for a moment comes from the TV, and he focuses on the rhythmic breathing from his little brat.

“You don’t have to think about that for a few more days,” he says, planting a kiss to her head and choosing to fight the way his eyes water when she sniffles softly. “You can use me as a jungle gym for a few more days.”

This, has her giggling, and he angles his head up at the ceiling because this is always the hardest part about being home, especially since he was kidnapped.

“I don’t like when you leave, Katsu-ni,” she mumbles.

“I know, baby.”

“Make me miss you…”

“I know- you know I miss you too.”

“Wish you didn’t have to keep goin’ ‘way…”

He swallows again.

“I know.”

May I request how it would be to be Remus little sibling?

being remus's adopted!sibling would include

constant bickering because you-swear-the-chocolate-wrappings-were-not-present-in-your-room-earlier-that-day or please-stop-stealing-my-sweater-you-have-literal-fur-i-have-nothing-and-its-fucking-cold

having a sibling would totally change his story in small but significant ways; he would love himself more if he knew there was someone to be responsible for. he would love himself more if he knew he had a sibling who won't hesitate to bite if he tries self-negative talks.

he'll be protective over you for sure; and he'd constantly make sure Sirius or James isn't flirting with you.

if you did have a relationship with either of them, it's obviously a secret. Remus would easily figure it out but that's another story.

bonding times are usually accompanied by fewer words. most common ones are reading in the same room or preparing cookies for events.

you force him to go shopping every month with you because everything he had looked the same and to be honest, sirius was the only one with proper fashion sense in his friend group.

he likes baking a lot. he'd show his appreciation for you with beautiful cupcakes (mostly right after fights 'cause that's his way of apologizing to you).

your school had dance and drama showcases etc and he's always in the front row seat with a camera. (even if it's the kind of thing teachers have to force you to participate.)

there are no secrets between you. it was one of the only promises he asked you to make — to tell him everything that's going on in your life.

this has helped you out a ton because whenever you fuck up, you call your brother first 'cause he'd never judge or scold.

lemme rephrase that, he will scold later yes but first he'd know what to do to unfuck the situation. he's the smart sibling fr.

the earliest happy memory you have is him holding you up to the sky when you were 9 or 10, pointing to the stars and promising you magic.

after the war, the stars became achingly beautiful. the worst was over, but a big part of you had gone.

you'd go to his headstone every week to talk, making sure he doesn't miss out anything in your life - just like he had made you promise.

Au where Hollow and Ghost survive and then SILKSONG happens but- hear me out, hear me out-

Hornet was so, so young when the infection destroyed Hallownest. All her abilities in silk are derived from violence and hunting— unlike her weaver brethren, she never delved deep into the arts or healing beyond the basics to survive the destroyed husk of the kingdom.

This has direct consequences when Hollow survives in HK. Despite Hornet’s best attempts, Hollow’s wounds don’t heal quite right.

Hornet can’t forgive herself, never mind the insane reality she managed to save a voided godling from the brink.

(When Pharloom steals her, when she realizes there’s a history of thread, where she can learn how to spin silk maybe to heal-

-at the terrible cost of herself to save people she loves?

Hornet’s never been great about self preservation. All her life, she’s watched other people throw themselves into the abyss.

Now it’s her turn.)

Alas. Her siblings do not agree with that mindset. And they’re going to get their sister back, hell or high water.

ANYWAYS SOME OTHER DOODLES

Mafia AU with the batfamily, but it starts when Jason comes back as the Red Hood.

In this AU, Dick is the first one to find out about Jason being a crime lord. He finds out that his little brother is alive and running a gang and says "fuck it."

Is Dick currently a police officer and vigilante? Yes. Does he also immediately quit his day job to join Red Hood's gang as soon as finds out? Also yes.

Dick has a second chance with his brother. Is this brother a little murderous? Sure. Dick's tried to kill people too, though. Also, Dick is 83% sure Tim's got a kill count. It's fine.

So Jason is confused why Dick is willing to join a gang. The oldest brother says some cringe worthy stuff about family and Jason takes the action as the proof of love and loyalty it is (also, somehow Dick is just as terrifying to their enemies as Red Hood, but Dick doesn't kill them).

Tim, upon seeing Dick join a gang, instantly researches the hell out of this group. He finds out it's Jason, runs the stats for how crime has dropped in Crime Alley, and instantly starts working behind the scenes to create a smoother path for them. Without meaning to, Tim becomes the shadow boss for Jason's gang. The brothers are not aware that the other gangs, mobs, and rogues are wary of whomever it is that's smoothly guiding Red Hood's gang to success.

Red Hood is the face, Nightwing (though maybe a different moniker) is his right-hand man, and there's someone steering them to victory.

The startling efficiency of the gang and quick ascent drives Bruce into a paranoid bender. The man also has no clue where Dick wandered off to and why he's ignorning Bruce. Tim, as Robin, pretends to try to help Batman take down this group. This causes mass amounts of confusion because no one is aware that Tim is helping Hood besides Tim himself.

When Damian first appears in Gotham, he doesn't immediately go to Wayne Manor. He stalks it first. And what does he find? Tim is apparently shadow controlling a major mafia in Gotham.

As some convulted plan to dethrone Tim from Robin (and also because Damian is not aware that shadow controlling a gang is against Bruce's rules [like how he doesn't know murder is a big no no]), Damian decides to infiltrate Jason's gang. At first it's rocky cause Jason doesn't want kids in that line of work, but Damian being Talia's kid (and the chance to provide Damian a better childhood) has Jason and Dick adopting the child. They try to keep the runt out of the work as much as possible.

They all (minus Tim) grow closer until one night Damian overhears Jason lamenting to Dick about how the Joker is still alive. Jason hates that his father never avenged him.

Damian decides to fix that by killing the Joker.

When Dick and Jason confront Damian about this, he reveals Tim is controlling their entire mafia from the shadows.
