Work Text:
God, this is such a headache.
Aizawa truly doesn’t understand why his class is always doing stupid shit.
After an excursion last weekend let to an electrical fire in a mall, class 1-A has lost their privilege to go off-campus. This was met with rage, disappointment, and many, many groans.
It’s their own damn fault! If you can’t act right, then you can’t go anywhere.
Of course, punishments can never be so simple.
He’s staring down at Bakugou’s request. It was sent a week in advance, like it always is.
Every single weekend, Bakugou goes off-campus. He’s never once caused a scene in public, and he’s always back before curfew.
Obviously, the ban isn’t fair to him. But, Aizawa can’t go back on his word. Nor can he make an exception, because that would cause a commotion.
He sighs and reads over the request again.
Every single Sunday, Bakugou leaves early in the morning to spend the day regressed with his caregiver. It’s—technically—a medical need.
Aizawa can’t just deny his student access to their caregiver. He’s hard on them, but he isn’t cruel. If anyone deserves a break from it all, it’s his most hardworking student.
“What are sighing about now, babe?” Yamada asks.
“Fucking Bakugou..”
His husband leans over to read the request.
“Yup, that’ll do it. Sucks his caregiver can’t just come here. Then, you wouldn’t have to deal with any upset kids.”
Aizawa stops. That’s actually..
“I knew there was a reason I married you,” He says while pulling out his phone.
“Um..thanks? I think?”
Nezu’s contact is pulled up quickly. That damn rat loves drama, after all.
“He passed the background check, just barely. He will be given a keycard, just until the grounding ends,” Aizawa explains.
Bakugou nods along, looking rather relieved. “Thank you, Sensei.”
“I’m not a monster. I’m not going to unjustly say you can’t see your caregiver.”
Katsuki just nods again. He fucking needs this. The only day off he allows himself, and the shitty extras almost ruined it.
As he heads back to his dorm, he’s already dialing Kariage’s number.
“—And if those idiots try to ruin my one day, I’m going to blow all of them to bits!” Katsuki rants.
“Okay, KitKat. Why don’t we lay down with Bunny, huh?” Kariage responds, being able to tell how tired his little is just by his voice.
Bakugou grumbles, but he stomps over and turns out his lights anyway. He also turns on his nightlight before curling up in bed with his stuffed animal mountain. Particularly, he holds onto his worn, green rabbit plushie.
“ ‘M in bed..”
“Good boy. Just get some rest, Kitty. Dada will be there on Sunday.”
“Okay..night night..”
“Night night, Baby.”
This kid is fucking excited.
Aizawa, of course, has seen a lot of his students regressed. He makes it a point to meet everyone’s little just as he met them while big.
That’s not to say he spends a lot of time around them when they’re regressed. Least of all, Bakugou Katsuki.
Bakugou is rather..secretive with his regression. He hates the attention—something Aizawa can relate to. He’s not one to run around the dorms, stuffie in hand and pacifier in his mouth.
At least, until today.
Currently, Bakugou is still in his skull pajamas and gripping a green stuffed rabbit the size of his torso. The pacifier in his mouth is orange with beads on the handle that spell ‘Kitty’.
He’s bouncing on his heels, but thankfully doesn’t try to run off.
In fact, before they left the dorm, Bakugou all but demanded Aizawa hold his hand.
At least the kid knows how to behave.
When his caregiver shows up—nine on the dot—Aizawa can’t help how his eyes widen.
The kid is in torn up jeans, a leather jacket covered in patches, and way more piercings than a kid should have. Not to mention the tattoo Aizawa can see peaking out of his shirt collar.
Bakugou shrieks when he sees him, taking off running.
The punk teen is quick to set down his bag and open his arms. He catches Bakugou and swings him around. High-pitched giggling fills the air.
Aizawa walks over much slower and picks up the bag. He does a quick search, finding only typical little gear inside.
The kid gets Bakugou’s settled on his hip and sticks out his free hand.
“Hey, I’m Kariage. I take it you’re Aizawa?”
Aizawa shakes his hand firmly. “I am. Welcome to UA.”
“Jeez, never thought I’d hear that. I’m excited to spend the day here.”
“Let me show you to the dorms.”
The walk there is filled with cooing and giggling. Bakugou can’t take his eyes off Kariage, as if he can’t believe the boy is here.
Aizawa is man enough to admit that it’s adorable.
He’s distracted enough that he forgets that he wanted to avoid the common room.
Immediately, as they walk in, tens of eyes snap to them.
“Uh..” Kariage awkwardly waves. “What’s up?”
Mina gasps. “Is that Bakugou?!”
“Aww, he’s little!” Ochako says.
“Who the hell are you?” Denki questions.
“Unauthorized persons should not be on campus or interacting with regressed students!” Iida declares.
“Oh, hi Kariage! Hi Kacchan!” Midoriya says with a wave.
“Sup Izu,” Kariage responds absentmindedly. His main focus is on soothing Bakugou, who looks one shout away from starting to scream.
“You know that guy, Mido-bro?” Kirishima asks.
“That’s Kariage. He’s Kacchan’s caregiver. Has been since he first presented in middle school.”
Now, that is news to Aizawa. To be caring for someone that long? The bond between those two is obviously stronger than he thought.
“In light of your grounding, Kariage has been given access to the dorms on campus to continue caring for Bakugou. If I hear of any problems, you will report directly to me. Understood?”
He gets a sick satisfaction at the fear on his students’s faces and their immediate response.
“Good. Be on your best behavior.” He turns to Bakugou, reaching out to ruffle the blonde’s hair. “You, too. No blowing anyone up.”
Bakugou puffs out his cheeks in defiance.
With that, Aizawa takes his leave.
Hopefully they all survive this.
It’s..nerve wracking, being stuck in a building with a bunch of heroes in training. Kariage is very grateful for Midoriya acting as a buffer.
“Hey, Izu, can you show me to his dorm? I need to get this one padded.”
“Woah, /Bakugou/ wears diapers?” Asks some blonde with a..lightning bolt through his hair?
Kariage glares at him, smirking when he shrinks. Then, he realizes the blonde is more scared of Midoriya’s glare and deflates a bit.
“Yeah, just follow me!” Izuku says with a smile.
“You’re a lifesaver, Midoriya.”
Diapering Katsuki is always a bit of a fight.
The poor blonde is emotional throughout the entire process. More often than not, he’s in tears by the end of it.
The embarrassment at his own needs is just too much sometimes.
What works best during changes is distraction. Midoriya being there makes it even easier.
Years of complicated feelings, petty rivalries, and jealousy are all forgotten whenever Katsuki is little. His favorite person in goddamn word—right after Kariage—is Izuku fucking Midoriya.
Currently, Midoriya is waggling Kat’s stuffed rabbit in front of him. The silly voice he’s doing is making Katsuki giggle and distracting him from Kari strapping up his diaper.
Once his pants are pulled back up, Katsuki is whining to be picked up again. He’s a bit of a velcro baby, preferring to spend every second in his caregiver’s arms.
“I’ve got you, Kitty.” Kariage picks Katsuki up and rests him on his hip again.
Izuku hands the little his rabbit with a smile. “You wanna go play, Kacchan?”
Katsuki babbles from behind his pacifier in response.
Going back down to the common room is honestly terrifying. Unfortunately, that’s where most of the toys are.
Katsuki seems to agree, based on the way he tucks his face in Kariage’s neck.
Even worse, the crowd seems to have grown. As if everyone wants to stop and stare at the elusive regressed Bakugou Katsuki
“Okay, Kacchan. What do you wanna play?” Izuku asks.
Katsuki just hides his face, blush climbing all the way up to his ears.
Kariage tries to coax him out. “Cmon, KitKat, you can’t hide in there forever. That doesn’t seem very fun.”
He gets nothing.
“What about dolls? You love dolls, right Kitty?”
That, at least, gets him Katsuki untucking his face. The blonde puffs his cheeks at him in a pout.
“Kitty, c'mon, don't look at me like that,“ Kariage says.
He sits down by the toy box, letting Katsuki get settled in his lap. There's no surprise when the little curls up further in his arms.
“Hey man! You're Kariage, right?“ One of the students asks.
Kariage squints at him, before mumbling, “Shitty hair..?“
Katsuki looks up quickly, cooing at the guy behind his pacifier.
The guy—shitty hair—actually barks out a laugh. “Of course that's how you know me.“
“Yeah, sorry. Kats doesn't do well with names.“
“I'm Kirishima Ejirou,“ He says, holding out a hand for him to shake.
Before he can, Katsuki grabs said hand and tugs at him. He whines for Kirishima to pay attention to him.
With a chuckle, Kirishima sits down next to them. “Hey, Bakubro.“
Katsuki whines pitifully.
“You can just call him Katsuki when he's like this. Or some nickname like I do,“ Kariage says.
“Well, hello, then, Katsuki.“
“Do you wanna play with Kirishima, Kacchan?“ Midoriya asks.
Katsuki, suddenly over his shyness, reaches for the bin of dolls. Midoriya pushes it in reach without a word.
Each boy has a doll shoved into their hands by Katsuki. The boy himself also grabs one, clumsily making it stand.
The four of them spend a bit playing. Read: trying to make sense of whatever chaos Katsuki is babbling about. It mostly consists of ass-kicking and explosions.
They're occasionally interrupted by one of their other classmates. They come over to introduce themselves and/or coo at Bakugou.
It's rare that Katsuki acknowledges them. When he does, Kariage makes sure to make note of it.
“You're Kariage, yeah? I'm Ochako Uraraka,“ A girl with pink cheeks tells him.
Katsuki quickly looks up. Kariage is the only one who isn't shocked when he latches onto her hand with a squeal.
The poor girl obviously has no idea what to do.
“You wanna play dolls?“ Kariage asks.
She smiles. “Sure.“
A doll is thrust into her hand, and the ass-kicking resumes.
It isn't long before Katsuki starts to get a bit fussy. He whines behind his pacifier, squirming.
Kariage slips a hand down to check his diaper, but finds him dry.
“Sorry guys, I think someone is hungry. I'm gonna go make him some mash and a bottle.“
“Ooh!“ Ochako excitedly sits up. “Can I give him his bottle?“
Kariage squints at her. There's something in the pitch of her voice that's tugging at his chest.
Then, he realizes.
“I don't know. Are you sure you're big enough?“ He days almost teasingly, already knowing the answer.
“I'm a big girl!“
“Well, okay then, big girl. You wanna be my helper in the kitchen?“
The regressed girl hops right up, practically vibrating with excitement. Kariage carefully stands himself, settling Katsuki on his hip.
He isn't surprised when Midoriya follows them to the kitchen. He talks quickly to Ochako about being good and listening.
Kariage is honestly thankful. He's never had to deal with older littles, considering Katsuki regresses almost exclusively to a year old.
He sets Katsuki down in one of the high-chairs. Giving him Bunny to distract him while Kariage peels and chops up some fruit.
He puts it in one of the silicon bowls they have, before handing Ochako the matching silicon masher.
“Can you mash these up really good for me, Ochako?“ He asks.
“Mhmm! I can!“
Midoriya nods behind her, silently promising to help her not make a mess.
Kariage turns his attention to making oatmeal and a bottle.
While Katsuki mostly takes bottles, he still needs proper sustinence. He also despises baby food. Thus, they came to the compromise of oatmeal.
He mixes the fruit with the warm oatmeal, setting it on the little's high chair.
When he goes to remove Katsuki's pacifier, he's met with resistance. Tears well up with his comfort item gone.
They quickly disappear once he starts being fed.
Meals are actually pretty easy with Katsuki. He can be fussy, but he isn't one to throw a tantrum and waste food.
He even earns extra praises for being a good boy while Ochako gives him a few bites.
After finishing his food, Katsuki whines while Kariage wipes his face. Then, he whines some more when he doesn't get his pacifier back.
Kariage shushes him as he picks him up, grabbing his bottle and heading back to the common room.
Ochako runs ahead, following his instruction to sit on the couch. Kariage carefully sits next to her, placing Katsuki in her lap.
The boy fusses, not liking to be away from his caregiver.
“Okay, Ochako. Hold the bottle like this, and remember to be gentle,“ Kariage intructs.
Kirishima and Midoriya both hover nearby. Their caregiver instincts are probably going haywire right now.
Ochako adjusts her grip on the bottle, holding it up to Katsuki's mouth.
”Here Kitty Kitty. Drink up,“ She says.
After some more encouragement from Kariage, Katsuki latches onto the nib and starts to drink.
Both littles get praised softly by all three caregivers. For being so gentle and so good.
Katsuki is barely awake by the time he finishes his bottle. Once the nib is pulled away, he starts whimpering.
Ochako seems scared, but Kariage takes Katsuki from her before he can start crying. He's also given Bunny and his pacifier.
“I need to get this one down for a nap, I think. Thank you for your help, Ochako.“
The girl beams up at him, chirping, “You’re welcome!”
“We have a naptime room over here,“ Kirishima says, guiding Kariage to the area.
Katsuki always takes a while to get settled. Even once the nightlight is on and he's in the crib, he's still whining.
Kirishima and Kariage are both by his side. With soft touches and softer words, they calm the boy down. They soothe him until his eyes flutter closed.
With that, Kirishima heads back to the common room, leaving Kariage with the sleeping boy.
Kariage brushes the hair from Katsuki’s eyes, smiling softly down at him. When Katsuki wakes up, Kari will be right here. For now, though, he’s content just watching over him.
