#rantaro fluff

After a few long hours of watching her get entranced in her work in her lab, Saihara ultimately leaves Kaede to her own devices and finds you in the dining hall when he decides he needs to eat before he collapses into bed. You also missed dinner, having allowed Angie to pull you along in her adventures around the Academy that afternoon, and are slumped back in your chair, staring at the wall when Shuichi enters. 

His arrival breaks you from your trance, and you nod at him when he raises a hand to greet you. You suppose you’re grateful that neither of you has a low enough opinion of the other to be wary of being alone together. You aren’t afraid of Saihara, and if he doesn’t feel the same about you, he’s at least kind enough not to show it. 

In fact, he apparently feels warm enough towards you to settle into a seat across from you once he has a snack in hand, but again, he’s gracious and doesn’t attempt small talk. It isn’t until he’s finished whatever’s in his cup that he speaks up. 

“Have you… remembered anything?”

You level a look at him. You may not be scared of him, but you aren’t necessarily jumping at the chance to discuss your “ultimate talent” with him. Or lack thereof. 

“If I did, I would tell you.” 

Despite your attempt to say it evenly, he senses the edge in your voice, and you in turn sense the wince from him as he registers your frustration with his question. For the third time that night, he is considerate to you and moves on politely, if a bit awkwardly. 

“...Rantaro mentioned that he felt bad.”

That gets your attention. 

“He was talking with me this morning about it. He asked if I had any theories on what might necessitate the two of you needing to be kept from that information. Apparently–” he hesitates. He doesn’t normally meet your eyes, nor anyone else’s, but he’s pretty pointedly avoiding eye contact now. “Apparently he got the sense that you were frustrated with not knowing. Said you felt like the two of you were being singled out.”

Well. Now things make a bit more sense. You had wondered why foot-in-mouth Saihara felt the need to bring this topic up when the two of you weren’t really close. He must sense the tension leaving you at his explanation, because he continues.

“I think he feels for you. I mean– he understands. I mean, obviously, he’s in the same boat, but he–”

It’s your turn to extend a kindness, so you cut off his rambling before it can get worse. 

“Shuichi, I get it. He’s concerned.” You think back to Saihara’s willingness to defend the two of you on the rare instances where someone did express suspicion. Why would the Mastermind do anything to single themself out from the rest of the group? I’m not convinced this is grounds for any real suspicion against either of them. Rantaro is even-tempered and easygoing enough to not let it bother him (not that you can see, at least), but having this gap in your memory on top of being stuck in a dome with sixteen strangers has been rough for you. It hasn’t helped that you haven’t been as quick to endear yourself to the others as Rantaro. Despite how mysterious he is, he has an undeniable charm that your courtesy can’t match. 

“It was sweet of you to check in. I’m glad I have people in my corner.”

Looking back, you should have stopped there. Saihara isn’t the only one who’s consistently at risk of saying things he’d rather not have let slip. But, as it so happens, you keep talking.

“I’ll talk to him tomorrow, let him know I’ll be okay. He’s worth sticking around for.”

Perhaps innocuous enough to you, but it can be easy to forget about Saihara’s deductive skills when he can barely make eye contact without losing his power of speech. You get up to leave as you make this remark, exiting too soon to catch the look on his face that indicates the gears are turning in his head. 

The next morning, you arrive at the dining hall for breakfast late enough that the very man you wanted to see is one of the only people left in the room. Saihara is leaving Rantaro’s table when you move to get your food, their conversation having apparently ended, and he meets your wave with a nod as he walks to the door. Rantaro smiles at you from his seat and greets you in his low, cool voice when you drop into the seat facing him. His easy smile and soft gaze make you want to keep any serious topics as far away from your conversation as possible, but there won’t be a better time to bring it up. 

“Saihara said you let him know you were concerned. About me.”

Rantaro looks sheepish at that, but you continue. No sense in making him feel bad about taking his concerns to other people when you aren’t upset. 

“I don’t like not knowing. And I don’t like feeling singled out. But I want to be done worrying about it. I know people aren’t going to turn around and point fingers at me if something goes wrong; you’ve made friends here, you’ve connected with people. I want that too.”

The neutral expression on his face as you spoke gives way to a smile as you both let your words process. The soft look in his eyes gradually gets replaced with something sharper. 

“The AV room should be free today.” 

He’s paid enough attention to you since you met to recognize from your expression that you don’t quite follow where he’s leading you. 

“If you want to build those connections. I’d like it if you started with me.”

As the two of you exit the dining hall on your way to the basement, Rantaro allows himself to hold onto the fact that it’s him, of all people, who you’re willing to trust. If he wasn’t willing to be honest with himself, he would be shooing away any thoughts of keeping everyone else from the AV room that day. But he’s here anyway, and he lets himself latch onto the idea of you leaning against his side as the two of you watch whatever you can get to play. 

On the floor above you, Saihara reaches the door to the Ultimate Pianist’s Lab, steeling his expression from the grin that has slipped onto his face.

As I wrote this I realized I was playing kind of fast and loose with "first" names versus family names and familiarity. Pretend I knew what I was doing. Also, this is pretty Shuichi heavy for a fic where the love interest is Rantaro, but my whole idea revolved around the reader getting "set up," so here we are.

Rantaro was def suspicious of you at first, he noticed something was off at first

This man LOVES your personality 100%

He thinks its amazing how brave and outgoing you are well being stuck in a killing game

So you guys get to talking and instantly click, becoming good friends :)

One day he asks about your ultimate, and you end up confirming his suspicions after a lot of bickering, and he offers to help you but an end to this killing game!

Eventually you start flirting with him and you see his reaction and- well its safe to say it turned you on.

So one day you invite him to your dorm and things got pretttyyyy steamy lmao. Wether you're top or not this man is sensitive as HELL. Like cums in 1-3 minutes sensitive lmao.

If he's topping he will always but your needs first and make sure you've came atleast once before him.

Even after that neither of you wanted to admit you liked each other, which annoyed pretty much everyone bc they could all tell you liked eachother

After you defeat the mastermind you confess to everyone your ultimate and ofc everyone is shocked, but most applaud you for your good work :)

After that your lives went to normal and Rantaro is getting tired of pretending you're just friends.. So...

"Hey, y/n? Theres something I've been meaning to talk to you about."

"What's up? Is everything okay?"

"Uh yeah, it is. So we've been friends for a while now and Im tired of hiding this. I like you, like romantically, would you like to go on a date sometime?"

"Yeah.. I would like that. Just.. Maybe don't tell anyone, okay?"

"Okay." He smiles tenderly and walks out of your room."

Shuichi

to be honest, I think he would find out before you did.

he is extremely observant so he would notice the symptoms right away

He would notice how you got fatigued easily, how you seemed to get nauseated

first, he would ask you if you were late

then, if you said yes, he would tell you straight up.

“S/o, you’re pregnant.” “I- I’m what!?” 

he would definitely get worried for you and his baby, 

a child born into a killing game is not ideal after all.

would be with you at all times, too scared to let you out his sight

he doesn’t want you or his baby to get hurt or killed by another student

yes, he believes in everyone but he can never be too careful.

he’s constantly pestering you and asking if you’re alright

you have 0 time to yourself, because he’s always with you

would probably hold hands through the bathroom door if you were using the toilet

he would try and prepare everything for when you go into labor

he wanted to make sure that both you and the baby are safe before and after labor

he takes care of you very well, always getting what you need or want

overall, i think he’d be a very responsible dad when the baby is born, probably the best dad out of everyone.

Kokichi

At first kokichi thought you were joking,

“Nishishi! Nice prank, s/o! You almost got me!”

But when you look at him with a serious expression, he goes-

“Wait shit, did we not use protection?” 

He’s not sure how to feel about it, so he just puts a fake face on.

He acts super excited and unworried but on the inside he’s not sure what to do.

he would constantly over think and become unsure of himself, the question repeating over and over in his head; Would he be a good dad?

Though he’s concerned for you and the baby, he’s actually kinda happy

he’s excited for all the pranks he and the baby can do against everyone in the killing game.

He has a new pranking partner!

yes, his pranking partner is less than a month old, but still! the baby is going to be a pranking master!

if you had strange cravings, he would try them with you

wanting to, “experience being pregnant with his tongue(kinky?)”

the horny bastard would probably still wanna smash, but definitely more gently than usual, he didn’t want to stab the baby with his dick

I think he’d talk to your baby via belly a lot

he would tell your baby stupid jokes that were kinda inappropriate but still hilarious

“Hmm, it must be nice being inside S/o. I would know, I was too.” 

“KOKICHI-” “NISHISHI!” *fucking books it*

i think he’d be a pretty irresponsible dad, but he’d definitely fight for his new family(with pranks)

random headcanon, but i think kokichi would wrap your baby in one of his checkered scarves when it comes out like- ahHHHHHHHHHH

he would also swaddle da baby with his scarf fvhajfgkgavkgbuyg

Korekiyo

When he found out, he was pretty shocked at first

But after the shock, he was insanely happy that he managed to create a human with you.

he adored the fact that his child would be able to make history and continue to live on even after he dies.

He loves humanity, so he’d love the human baby he made with you even more

during your 9 months of pregnancy, he would praise you and your ‘glowing body’ daily

constantly saying stuff like, “Your body is a temple and you are a Goddess.” and “The life growing inside you simply amazing and I am proud to share this experience with an entity such as you.”

You know, that cheesy ooey gooey romantic shit

“S/o, I want to crawl into your body so I can experience being born aga-” “That’s enough of that.”

It's cute and all, but it sometimes gets embarrassing when he is basically worshipping you in public(especially like that).

i think he would tell the baby, folk tales and myths while it was still in your belly

he wanted to raise the baby to be just as curious as he is.

though, behind all these adorable things, kiyo is worried.

don't get me wrong, he does enjoy the other students’ thoughts and strange minds, but he doesn’t trust them for a second.

he would never willingly leave you with another student.

he gets a teensy bit controlling; always asking you to stay in his lab or dorm.

but he won’t get unreasonably angry if you go anywhere else, he just encourages staying in places with less people

if you do need to go somewhere else with other people, he would just follow you

in the end, I think kiyo would be a dad that never neglects his kid(can’t relate-).

he would always be there for them.

K1-B0

K1-B0 doesn’t have the facilities to knock anyone up.

like kokichi asked, do robots even have a penis???? 

how the hell did you two fuck in the first place!????!

but if somehow, miu gives him a penis and actual sperm??? I guess it could work?? i don't know how it works man- I've never fucked a robot

I think he’d be happy and proud that he managed to impregnate you

“See!? I can do human things too!” “...Impregnating a human, K1B0? Seriously? Too fucking far.”

okay, I can’t take this one seriously T_T

um, if you and K1B0 had a baby, would it be half robot??

through your belly, the baby would make robot noises to communicate and K1B0 would understand which is cool

when the baby was born, he gets very protective; he doesn't want his baby to face the same discrimination and bullying he did

he wouldn’t be afraid that the others would hurt the baby, because he helped build in lazer eyes for his baby.

oh but he definitely would not let his baby go near Miu at all

he would prevent that from happening as much as possible

he’s afraid she’ll do something weird to the baby and add new gadgets,

sure its cool and all for him, but the baby is so young!

I DONT KNOW WHAT THIS IS ABVHGJDFKVJGVJ

Kaito

Kaito would be fucking psyched when you told him, stars in his eyes and everything

“I-I’m gonna be a dad!? whOOOOOOOOOOO!!” He picked you up and hugged you tight, but not too tight; he didn't want to hurt the baby.

But then realization hits him like a truck when he realizes, that the baby was going to be born into a killing game.

He would have a nervous breakdown and cry for about, ehhh a day or so

but once he gets it all out, he focuses on the positives

if it was possible, he loves you even more than he did before!

now that you have a mini you growing inside you(inception!?), its like, double the love :0

he’s giddy everytime he sees you with your baby bump, not being able to resist hugging you every time he sees you.

he loves you so much, it's hard to put in words 

he cries when he can feel the baby kick, kissing your belly uwu

when you’re around people he can’t trust in the killing game, he gets very very protective

he would watch their every move, moving to shield you when they move their hands.

but around the people he trusts like shuichi and maki, he’d let his guard down and relax

he would stress out if you were in any discomfort, always making sure you were okay

if your legs or back were sore, he would be there in an instant to massage your joints until his hands fell off

he puts you before himself, sometimes forgetting to take care of his basic needs like, eating or sleeping

you’d have to remind him a lot

I think something cute that he would do while you two slept is holding you or your belly protectively while he dozed off

overall, a goofy dad that makes stupid dad jokes.

would have a lot of proud dad moments

he seems like the type who would embarrass his child a lot lmao

Gonta

uh, gonta is father?

would definitely be shocked and stressed out when you told him

his protective mom dad instinct would intensify and he would constantly be carrying you

1. because he didn’t want your legs to get tired

2. he’s practicing for when he picks up his baby

3. if he carries you like this, no one can reach and/or hurt you

4. because he can

5. and because a gentleman would do that

he doesn't really know what to do when you’re having pregnancy symptoms, like vomiting, nausea, etc.

he’s not great at that part, but he knows how to protect you from danger and he knows how to make sure you’re comfortable

he treats you like a queen(as all women should be treated!)

he isn’t really worried when you’re around other students, but he still picks you up just in case

i think he’d act super sweet, like his sweetness would intensify to 100

he would try cooking a meal for you or giving you breakfast in bed, but it always tastes like boiled eggs in the end?

like no matter what it is, it always tastes like boiled eggs

pasta? boiled eggs

maki rolls(haha)? boiled eggs

sandwich? boiled eggs

“...Mmm! Gonta this is, uh, not at all tasting like boiled eggs!” You tried to say enthusiastically, Gonta nodded with a soft smile, “Gonta glad you like it!”

eventually you caved in and told him(after a few months... you didn't want to hurt the baby—gonta—, okay?)

he’d have to ask kirumi to do all the cooking while he just handed her ingredients

he feels weird when he thinks about the fact that his baby is growing inside you

all he can think about is larva

but he thinks its cool that his creation is going to grow inside you and become another human

so he just rolls with it

Rantaro

(i apologize in advance if this isn’t too accurate)

i feel like i can imagine this:

Rantaro was sitting on the benches outside, drinking his bottled tea. His eyes darted towards your approaching figure. He stored his leftover tea in his cheeks as he gave you a wave, putting his bottle down. “Rantaro, i’m pregnant.” His eyes widened as the tea came spewing out, luckily he turned his head away so you were out of the splash-zone. He dropped his bottle before standing up and immediately hugging you. “I love you so much, we can do this. I love you.” He repeated as he moved his hand up your head, tangling his fingers in your locks.

he would be pester you if you looked like you were in pain or struggling with something, thinking you were going into labor

*breathing pattern changes* “Holy shit! Are you going into labor?? Fuck, okay um, uH hospital?? UH contRACTIOns HOw LoNg?-” “I JUST BREATHED DIFFERENTLY.”

p a n i c

he doesn’t know how the whole pregnancy thing works, he’s only a teen after all

but no matter what, he supports you in any way he can

i think if anyone made a bad comment about your baby or you, he would probably scare the shit out of them with his scary expression

intimidation x100

i headcanon him to be a cuddly dad

he would hold you a lot, he likes feeling all three of you together

small scenario from when the baby was born;

As your baby’s cries filled the room, you sighed as you got up from the bed. Rantaro, however, abruptly stopped your movement, “Don’t worry, I got ‘em.” He rubbed his eyes, kissing your forehead as he gently pushed you back down onto the bed and walked towards the crib.

You watched with droopy eyes as Rantaro gently shushed the baby by bouncing them in his arms. Rantaro made his way back to bed and slipped in beside you, the now quiet baby still in his arms. “Mmm Rantaro no, we’re gonna crush the baby.”

You softly groaned in protest. Rantaro pouted at you, silently pleading with you with his puppy-dog eyes. You let out a huff of defeat before nodding, eyes half-closed. The last thing you saw before dozing off was Rantaro smiling goofily at the baby. You slowly fell asleep, Imprinting a gentle smile on your face as you slept. 

sorry for steering the other way for rantaro’s, its 6am ;-; what is sleep anyway? phew, thank you for requesting this! i enjoyed writing it, it was fun :D

A: attractive (what do they find attractive about each other?)

Rantaro would find your unexpectedly cute side attractive,

like when you secretly tries to bake avocado biscuits for him, secretly sleeps with stuffed animals... He find all of this very attractive from you.

So he will sometimes sneak at you when you're alone and took some pictures about you and your cute side about it.

Unexpectedly,you didn't even notice! He couldn't help but chuckled about it

G: gentle(are they gentle? If so how?)

His name is RANTARO, you expect him to nOT be gentle? Not happening

He could probably be the person with the most gentle trait than the others, he loves looking at you tenderly everytime, do anything to you gently,

Tuck you to sleep, cuddling with you, or even talking to you, he would be very gentle to you, not wanting you to feel uncomfortable around him.

Whenever you told him that he is being to gentle and he doesn't need to be that wary around you, he would just let out a smile and shook his head, implying that he isn't wary around you,

he just wants you to feel comfortable around him, and stated that you don't need to mind him.

E: everything ( you are my.... E.g. my life, my world)

" Rantaro, what am I to you?"

He chuckled, as he patted your head as he look at you tenderly

" let's see~ you're -"

He stopped and look at you afterwards, you with your excited look really made him giggle

" why did you stop?"

You pouted when you found out him looking at you, asking him with an angry tone.

" fufu.. aight aight- you're my lil avocado baby okay?"

J: jealousy (do they get jealous?)

Hmm I think yeah, Rantaro would get jealous,but not that strong like kokichi.

He would be the one who wouldn't show it out when he's jealous and would Solve things secretly

He wouldn't want to get in a fight with you so he would solve things on the day that happened

When you ask him what had happened to him he wouldn't tell you about his jealousy, he would still put out a smile on you implying that he's alright.

When you actually found out that he's jealous he would feel quite embarrassing about it, knowing that he would also do such childish action.

K: kiss( how do they kiss? Who initiated the kiss)

Rantaro would initiate the kiss-

He would kiss you when you're not paying attention just to see your flustered look with a slight of surprise, and then take a pic of it again-

Rantaro would just chat with you like normal, and looking for a chance for you to pay attention to other stuffs and just placed his lips on yours, hand Holding your chin, and look at you with tender eyes.

◊ Every single plushy you gift to him, he cherishes. He loves you a lot, so obtaining a plushy that was made by you kind of makes him feel as if you gave him a token of your love. So he’d thank you by kissing your face all over, uttering words of gratitude.  

◊ He had been searching for you, and so when he found you he nearly cried out in joy. He found you cuddled up and fast asleep with one of your almost finished plushies. He wouldn’t want to wake you up, but he just needed to cuddle you and make sure to tell you how much he loves you. After snapping a few photos, of course. He’d make you his lock screen. 

◊ “Hey, baby…” Putting his phone down on your work table, he would murmur into your ear, leant down to your level and near your face. Seeing your face close-up made him kiss your cheeks subconsciously, which made you stir awake. You sneakily peaked at Rantaro’s face love-sick with one of your eyes, closing both of them once again to fall back asleep. “Are you awake?” You nodded your head against your plush pillow, nuzzling the side of your face further in it. 

◊ “... You gonna get up?” He snorted at how adorable you were, silently ‘aw’ing underneath his breath. Shaking your head, “mm waiting for more kisses.” You mumbled, sleep laced in your voice. Your hearing intensified due to how sleepy you were, so you could hear his shirt shuffling as he reached down to pet your hair. The voice of your beloved sounding rough as he laughed, it made you smile in your half-asleep state. 

◊ Giving you what you wanted so much, he pecked your eyelids, cheeks, nose and forehead before pressing a small but loving kiss to your lips. Lingering for a moment and grinning as he felt you slightly pucker your lips to kiss him back. Pulling away, he saw your once closed eyes, half-open and staring at him with confusion, as if saying, “Why’d you stop?” 

◊ “You’re so sneaky,” He quietly giggled, responding to your grabby hands by carefully gripping each side of your hips and lifting you up to press against him. The plushy was held between the two of yours’ chest, feeling squished and soft against both of you. “I love it.” He nuzzled his nose against yours, smiling wide at your flustered reaction. 

◊ Loves opening up his phone just to see a picture of you being so fucking adorable. He would end up forgetting why he opened his phone and instead left it to find and hug you.

◊ Though he adores seeing your little face all squished up to your soft plushies, he gets jealous that that wasn’t him. Yes, he’s jealous of a small plushy. He really prefers you cuddle him instead of the plushy, although he wouldn’t mind holding you and the plushies close.

◊ He likes surprising you whilst you make a plushy, back hugging you and hearing you squeak at his sudden touch. He doesn’t like, however, if you work on a plushy for too long and end up losing track of time, forgetting to eat or even leave your workstation.

◊ He’d scold you but if you showed him your plushy, he’d go soft. “You should’ve at least set a timer-” You whipped out your plushy from behind your back, presenting it in front of his face, his once, somewhat stern eyes were now watering slightly, a look of pure adoration in them.“... S/o, you can’t do that.”
