Chapter Text
To be quite honest, Yaoyorozu was unsure of how this all happened, solely because of how quickly it happened in the first place. One moment her and a few others were walking to the book store located on the west...no, east side of the mall when Kaminari had suddenly been tackled by a young child who looked no older than 6. A distraught older woman came running up behind, apologizing loudly as a loud bang came from the floor and pale yellow smoke emerged from the child.
Obviously a quirk at hand, Yaoyorozu had attempted to contact Aizawa before realizing he was not who accompanied them on the trip, but Midnight rather. Nonetheless, she called the 18-rated hero with increasing panic as the yellow smoke got thicker. Kaminari stood up form the floor, child in his arms and a hand over his nose and mouth. He handed the kid back to woman, trying to reassure her that everything was fine and attempted to waft the smoke away with the help of some of the others in her little group.
Then the quirk activated. It went downhill quickly, to be frank. Kaminari soon enough was back on the floor, shrinking as the woman tried to help but most likely having no clue of what to do. Turns out it was her quirk that had changed Kaminari apparently. Fun.
Now, Midnight was cradling a sleeping little boy (in a bundle of his own now too-big clothing and a small blanket the woman bought for them in apologies) who looked suspiciously a lot like her classmate. Yaoyorozu explained to the best of her ability a quick run down of what happened to her teacher, but the hero looked pretty occupied in making sure what she assumed was Kaminari stayed asleep. Considering his size, she gathered that he couldn’t have been any older than 4 or 5. They waited for the mall security to come by and assess the situation since the woman did use her quirk, but let them leave quickly afterwards to return to the dorms. Midnight asked for Yaoyorozu to send a warning text to the rest of her classmates of Kaminari’s current...state, so they could prepare.
Midoriya was busy freaking out to the left of her as they walked to the dorms, taking imaginary notes on his hand while muttering something about the woman’s quirk. She already explained it was a simple de-aging kind of quirk, that had a somewhat short time span. 3 days at least, a week at most, she whispered to Midnight loud enough for Yaoyorozu to hear.
Tsuyu took one glance at her and tilted her head, her tongue coming out of the side of her mouth with a finger poised at her dimple, presumably asking a non-verbal question. Yaoyorozu flustered under the sudden gaze, shifting out of the way for Midnight to reach the couch. Ashido came racing down the floors fast once she heard the news, squealing.
“Is it true?! Did Kami get turned into a little baby??”
Hagakure was right behind her, squealing just as much with enough passion to fill a gallon jug. “Where is he?? I wanna see a baby Kaminari!”
Said bundle of clothing stirred on the couch, stilling when Midnight gently patted it and releasing the tiniest bit of her quirk. It did the trick to get Midoriya’s attention though, prompting him to rant off in awe about the control of Midnight’s quirk.
Aizawa came into the dorms roughly 15 minutes later with Recovery Girl behind him, sighing at the sight before him. Ashido and Hagakure trying to poke a bundle of clothing and blankets, Midoriya rambling at 5,000 words a second, and most of the class now coming down to the common room. Recovery Girl took no hesitation in prying the girls off the poor kid, being careful to stir him awake. The class waited in silence with a few murmurs from the recently informed students. Uraraka nearly wailed when Kaminari poked his head out of the bundle, a cascade of bright blonde hair running down his back. For a moment, minus the ever-present black lightning bolt, Aizawa could’ve mistaken his student for a much, much, much younger Present Mic.
Recovery Girl briefly checked him over, using her “doctor voice” as little as possible and slipping into what Aizawa called her “little children’s nurse” voice. Kaminari responded to her either way, keeping his words short and blunt with eyes locked into hers as much as she would maintain the eye contact. A little unsettling, but Aizawa naturally had uneasiness around small children. Recovery Girl tsked quietly and moved to hold Kaminari’s hands in hers to keep them from shaking too much while she finished up looking him over.
Kaminari looked blankly at his classmates after Recovery Girl left with Midnight, settling his gaze on Midoriya and tapping his small fingers on those impossibly small knees hidden by the blanket that cocooned him.
“What time is it?”
“W-what?”
Kaminari had abruptly switched to English, which probably made up for the fact that all he said in Japanese was a simple yes or no. He stayed unwavering however, seeping his gaze into Midoriya’s forehead as if to see how much of a brain he had in there.
“What time is it?”
Aizawa had heard that phrase enough times to know what he was asking, even with his utter lack of understanding when it came to English, and let Kaminari see his watch, assuming the kid knew how to read clocks. It seemed he did, because as soon Kaminari looked at the watch he appeared to relax. Aizawa turned to his students after a moment of watching Kaminari pick at his baggy shirt and fiddle nervously.
“Yaoyorozu, do you know how to make clothing?”
A nod and some shuffling around led him to believe she went off to go make some in private, a few of the girls trailing behind more than likely to suggest patterns.
“You wouldn’t happen to know where my parents are, would you?”
Aizawa sighed and pulled his phone out, quickly texting Mic to get his ass over to the 1-A dorms ASAP and held up a finger towards the child as the universal sign for “give me a minute.” He wasn’t equipped to deal with a child who spoke mostly English and broken Japanese. Aoyama waltzed up to child-Kaminari, grinning ear to ear in a casual manner that almost made him forget this was Aoyama we’re talking about here.
Aoyama’s English was mediocore, after all his native tongue was french, but he held a decent enough conversation with Kaminari to capture his attention while Mic took his sweet ass time. The girls came back within a few minutes with new clothing for Kaminari, causing him to break away from his conversation with the forever sparkling student. Ashido was holding a hairbrush and a few hair-ties, a mischievous smile on her face while Yaoyorozu held a little stack, looking proud of her creations.
“I wasn’t sure of his size, or how easy it would be to dress him considering he’s so young so I made a few simple long shirts in case.”
Aizawa threw her a nod, swiftly opening the door as soon as he heard Mic and ushering him towards the now baby-faced student. A few more students got comfortable finally, including one Bakugou Katsuki who surprisingly had yet to utter a word. He mostly just watched with the others in faint curiosity and mock disgust.
Kaminari seemed unnaturally calm and collected being surrounded by adults and teens than a normal child would be, so maybe he still had his...teenage brain? His current brain, more like it. Mic made quick work of switching to English to talk to young Kaminari, asking him questions and answering the few that Kaminari had himself. The blank stare that had made itself known on Kaminari’s face was getting a little more unsettling the more it intensified and twitched. With startling realization, Aizawa focused a little harder on Kaminari’s face and found that his eyes weren’t the gold he’d been accustomed to...they were blue. A bright blue, at that. He’d heard from Recovery Girl once that a severe enough concussion or contusion can mysteriously cause a change of eye color somehow. Even with the birth of quirks, the phenomenon of eye color changing injuries has still yet to be explained. Maybe that’s what happened with him? Though the more logical reasoning would be that Kaminari simply wore colored contacts.
Mic took the clothing from Yaoyorozu and presented it to the young child, prompting him in English to choose something to wear. Kaminari looked at the stack and chose the first item on top, which was washed out green long shirt with little splotches of blue to vaguely resemble flowers. Mic tapped on Kaminari’s knee, asking the boy if he could dress himself. He nodded, so reasonably Mic scooped him up with the bundle to take him to the bathroom. Ashido looked a little saddened at not getting to pounce on his locks of hair just yet, but was soothed by Tsuyu’s offer to brush her own hair.
Aizawa rubbed his forehead, feeling an oncoming headache and sat down on the couch. The students burst in conversation, all talking of the same subject.
Sero scratched at his elbow uncomfortably and looked over to Ojiro. “I thought Kami would be a little more...excitable as a kid.”
Ojiro responded with his own nervous tick, swaying his tail lightly and tried to get make sense of the situation. “Maybe he’s just...uhm...I don’t know, confused?”
Mic and Kaminari came back after a couple minutes, Kaminari dressed in the shirt he picked and presumably some smaller shorts underneath whilst holding onto Mic’s index finger. Ashido poked Yaoyorozu with the hair brush, asking her translate (despite the fact that Mic was literally right there and fluent) so that she could play with Kaminari’s hair. Yaoyorozu’s knelt down as best she could to get to Kaminari’s new height, blinking in shock at his electric blue eyes but smiled sweetly nonetheless.
“My name is Yaoyorozu Momo, and my friend Ashido wanted to know if she could play with your hair,” Yaoyorozu paused and mumbled something in Japanese under her breath. “You can say no if you want.”
Kaminari considered her words with a hint of expression on his face, still holding tightly onto Mic and whispered. “...If you are gentle, then I will allow it..”
He paused like Yaoyorozu did for a moment and looked up at her, a ghost of a smile briefing his lips. “Your name is long...may I call you Yaomomo?”
It was the same nickname that current, well older, Kaminari had started to call Yaoyorozu, so she allowed it with a nod and helped him onto the couch where Ashido awaited. Kaminari reluctantly let go of Mic’s finger, grasping onto “Yaomomo’s” instead. Ashido squealed in excitement as the girls gushed over his hair, some of the boys even gathering. Mic slipped up to Aizawa unnoticed to the students to watch them.
Kaminari squirmed under the attention but otherwise kept a solid poker-face, occasionally asking the time from Aizawa. Aizawa was tempted to just give the kid his watch but also didn’t want to give an item of his to a small child who probably would swallow the damn thing if unsupervised considering he’s still Kaminari.
Mic whispered lowly right next to ear, a hand grazing his back. “I asked him how old he was, or thought he was, and damn kid said he was 10. There’s no possible way he could look that small and be 10 years old. I know a lot of kids go through a hell of a puberty when they reach highschool but that’s a lot of growing.”
There was a difference, Aizawa realized, between Mineta and Kaminari. Mineta was the smallest person in class, just a few inches shy of Aizawa’s waist. Kaminari was nearly the same height as Mineta, though even shorter. The difference came in the body structure. Mineta was roughly proportioned with his body, looking more like a shrunken teen than a small child in comparison to Kaminari. Kaminari had the full child package with a big head and features too big or small for his face.
Ashido carefully braided Kaminari’s hair, occasionally pausing to let whoever wanted to touch it to feel it (after Kaminari’s permission of course) and trying to ask him questions in broken English. Kaminari picked at his ankles, leaning into the hands when they came to ruffle his hair and tried his best to answer in broken Japanese.
Finally Bakugou decided to speak up after having stared at Kaminari’s baby face for long enough. “So where the hell is he gonna sleep? Little fucker is too young or small to be by himself.”
How considerate.
Aizawa sighed from the couch, slipping further and further into the arm of it. “Unless one of you want to volunteer, he’ll stay with either me or Mic, I suppose. Are any of you experienced with kids?”
Tsuyu raised a hand slightly, trying to teach Kaminari how to braid by practicing on her own hair. “I have younger siblings that I care for, kero, I could watch him if that’s okay, Sensei.”
It was logical and a quick solution, so Aizawa approved and immediately fucked off to catch some sleep before he went on patrol, leaving Mic to be the remaining adult in the common room. It was only 6:47 in the afternoon by that time and a few of the students were beginning to get bored just watching the now small blond child blink every few minutes like he had the emotional and facial expanse of a rock. Shouji suggested a movie to the others, to which they mostly agreed. Mic left for a moment to go get a few dvds for them, leaving the kids in mostly silence.
It was...extremely awkward, to say the least. They really, honestly, expected Kaminari to more or less the same, if not even more rambunctious and rowdy. What they got instead was some weird, quiet kid who reminded them a little bit too much of Todoroki, who was currently having his own staring contest with said kid. Mic came back eventually with a few genres tucked under his arm and had everyone vote, making sure the choices were still kid-friendly. Kaminari soon enough pried his newly braided hair from Ashido and scrambled off the couch, toddling his way over to Todoroki and making himself home on the teen’s left side. Hagakure definitely made sure to snap enough pictures of that sight.
The “Bakusquad” also definitely made sure to keep an eye on their now youngest member, wary of the crossing of squads. It was a little silly, but the “squads” tended to take themselves quite seriously. Not like they could stop each other from making friends between the squads but still, they’re only teenagers and teenagers usually liked a sense of belonging within a group.
Kaminari seemed to realize that a movie was playing and was aware of it enough to lower his voice when asking for the time. As soon as 8:00 pm came near the end of the movie, Kaminari immediately fell asleep into Todoroki’s lap. Mic shooed all the students off to bed given that the next day was a school day and made sure that Tsuyu picked up Kaminari.
He was light, she acknowledged on her ascent to her dorm room. Ashido still attempted to fuss with his hair, though Tsuyu made it clear that she didn’t want him waking up. Jirou offered to let her change in her room after she set Kaminari down for bed, though she decided to use the bathroom. Tsuyu figured it shouldn’t be too much of a problem to let him stay in the same bed as her (considering he wouldn’t even take up a quarter of her bed) though she hoped it wouldn’t bother him. As clingy and touch starved as regular-Kaminari liked to act, she did notice from time to time that he would hole himself up in his room. As Tsuyu crawled into her bed after turning the fan on, Kaminari sleepily reached out for her, grasping her thumb and asking for the time once more in a quiet voice.
“It’s 8:17, Kaminari-kun. Please try to rest. If you need one thing...no, something, let me know, kero.”
Tsuyu’s English wasn’t necessarily bad, but she was nowhere near fluent enough to talk to him casually, thus decided to stick to basic sentences that she knew. She hoped he understood her regardless. Kaminari curled into the smallest ball he could possibly be, still gripping her thumb, and fell back asleep.
