In which Bakugou Katsuki pisses off a young man so much that next thing you know Midoriya is taking care of him… as a child!
You Might As Well Be One!
Bakugou Katsuki is known to be a ball of anger and mismanagement that people tend to respect due to his high intelligence and crazy power. As he walked down the streets towards his home, he encountered a child walking a dog. He paid them no mid as he trailed on but heard the dog growl at his presence, he turned around to be met with a pissed off dog and the kid who was wearing thick black framed glasses held him back.
"Kacchan! Cut it out!" the kid scolded the ashy blonde dog as he took one las look at Bakugou and turned around, he saw the metal plate around the collar and caught the glimpse of 'Kacchan' on the dog's name tag.
"Oi… what's your dog's name again?" he felt heat around his palms as he looked straight at the kid. The kid fixed his glasses, golden eyes looking straight at his red ones.
"Kacchan," the kid replied. He turned his head slightly to his side. "Ah! You're the one that I named my dog after!"
"You got some nerve!" Bakugou yelled irritated as he tried to keep his explosions at bay. Kacchan (the dog) barked at him angrily, taking a defensive stance in front of his owner. The kid looked unfazed.
"Don't trigger Kacchan…" the kid looked pissed as he tugged back his dog towards him and he retreated slowly. "You're years older than I am and you're acting like a kid; you might as well be one!"
"Huh?" Bakugou was pissed at the shortie in front of him. "Listen you twerp, give your dog another name,"
"His name is Kacchan, not Bakugou Katsuki," the kid defended.
"You still meant to name him after me!" Bakugou clenched his teeth angrily.
"That's it!" the kid stepped forward, removing his glasses, there was a bright flash of light and Bakugou fell to the ground he felt pain all over his body, all he made out was the kid's golden eyes were now a bright neon yellow and a small smirk. He lost consciousness. "This gotta teach him a lesson."
Midoriya was just arriving home after hitting the gym with Iida and Todoroki after school, he was reaching the steps when… he blinked a couple of times. In front of his steps was a small lump, he walked carefully towards it, nestled inside the clothing, which seemed to be the UA uniform was no other than Kacchan... as a child.
"AAAGGGHHHHHHH!" Midoriya screamed loudly in terror, Midoriya's mother blasted out the door when she heard her son scream so loudly, stirring up some resting birds. "MOM! LOOK!"
"Eh?" Inko looked down as where her son was pointing, her eyes widening as another piercing shriek came out from her this time. Eventually, the small child woke up, blinking a couple times before realizing where he was.
"Deku?! Auntie Inko?!" the small child yelled surprised. "Why am I naked?!" the child exclaimed loudly.
"Ahh… Kacchan, why are you here? Like that?" the naked child looked everywhere, then put his hands up towards Inko. Unconsciously Inko picked up the child with his white shirt as a cover.
"Hurry in Izuku! It's cold out and be it how it may be, Katsuki-kun is still a child for some reason," Inko then hurried in with her son behind him, after digging through some of Midoriya's old stuff, both Midoriya's looked at Bakugou in confusion, expecting him to say something since he had remained silent this whole time. "Do you want some food Katsuki-kun?" Inko smiled sweetly and Bakugou nodded. "Take care of him, Izuku." The older woman left the two alone to go ahead and cook. Midoriya set his eye back on Bakugou.
"Um… so…"
"He lives in the neighborhood and has a quirk to take make you a child," Midoriya blinked confused. "His dog has the same name as me!" the little boy exploded in irritation, he looked at his palms in anger. "He took me back just enough so that my quirk becomes useless…"
"A quirk… that makes you a child?" Midoriya's eyes widened in pure amazement, and then he felt the slap of Bakugou's small hand against his face, smacking him multiple times.
"Baka Deku! I need to train and surpass you and now I'm stuck in this useless body of mine!" the small kid kept smacking at him.
"C- Calm down Kacchan!" Deku grabbed a hold of both of his little hands and lifted him up, restraining the little rascal.
"Don't call me that! He named his dog that!"
"Who did!?"
"The brat who did this to me!" Bakugou was fuming, he looked on the verge of tears.
"W- We'll find him okay? For now… we need to call your mom…?"
"Tell Auntie Inko to call her and tell her I'm sleeping over," Bakugou ordered, Midoriya nodded, taking orders from the small child.
"You two come down for dinner!" Inko called from downstairs. Bakugou walked ahead of him and Midoriya followed behind him. At the dinner table Inko nodded and called Bakugou's mother who was too excited about the fact that her Katsuki was going to spend time with her cute Izu-chan. Eventually night came around and the futon Midoriya had prepared for Bakugou was rendered useless since the small child decided to sleep on the bed.
"Shut up Deku! I'm in a child body and need to be more warm!" and he wrapped himself up in his blanket and fell sleep right away.
"I'm off now!" Midoriya called as he waved him mom off, young Bakugou in tow. Midoriya held his face along with his mother.
"You look so cute Kacchan/ Katsuki-kun!" the two Midoriya's awed, pissing off and also making the ashy blonde kid puff up proudly. As the two walked, Bakugou looked all over the place trying to find something.
"Stupid Deku! Pick me up!" Bakugou ordered, lifting his arms up, Midoriya nodded, lifting the small child who quickly climbed to his shoulders to look ahead. "Where's that dumb dog…" Bakugou murmured, they eventually arrived to school where Midoriya had to be very discreet with Bakugou in tow, in the most sneaky way possible… he made it to recovery girl's place, where the older woman smiled sweetly at him.
"Midoriya-kun… it's quite early to be here already!" Midoriya shook his head.
"Gomen, but it's not about me… not this time…" Midoriya scratched his head. "It's about Kacchan…"
"Bakugou-kun?" her small eyes widened as from Midoriya's back, appeared a small child, who looked exactly like Bakugou Katsuki. She gasped. "I expect quite the story here." After Bakugou explained what had happened Recovery Girl examined him.
"So what do we do?" Midoriya asked.
"I will speak with the teachers, you can attend class, Bakugou-kun is healthy and his mind seems to remain at his level but with a body of a three or four-year old his quirk is pretty much nonexistent…" Recovery girl looked at the child once more and sighed. "With the description of the person that did this to you, we'll be able to find the culprit much faster as well. For now, head to class,"
Class 1-A was as loud as always, Midoriya was extremely nervous and Bakugou seemed slightly nervous as well. Recovery girl had mention that while his mind was still his age, his body made him react as a three, four-year old anyway which made him at times, weak of mind. The door opened and Midoriya walked in, Bakugou on the top of his shoulders, he needed to feel tall.
"Eh, Midoriya-kun, who's that on your shoulders?" Iida asked. "It's not allowed for children to be here!"
"Shut up four-eyes! It's me!" the small child barked angrily. The class then paid attention to the young child on Midoriya's shoulder.
"B- Bakugou?!" the class yelled in unison as the class door opened and in entered their teacher, Aizawa Shouta.
"Silence," the teacher lifted his hand and smacked a textbook to the table in front of him. "As most of you may have noticed, Bakugou did something dumb and now he's a child. I don't want this to be a distraction but this is also not a daycare," his eyes locked on Midoriya who gulped. "Midoriya, you're to look after Bakugou until we find who the culprit is."
"Yes sir!" Midoriya agreed as the young child clicked his tongue in annoyance. And so, Midoriya had to carry him around… everywhere. Once lunch hit around, Bakugou felt annoyed at the stare of Iida, Todoroki and Uraraka on him.
"STOP STARING AT ME!" the young Bakugou yelled in annoyance at being put on the spot.
"It's hard considering you're a child all of a sudden," Todoroki said matter-of-factly. Pissing Bakugou even more.
"Shut up you thermostat! Deku! I want to eat somewhere else!"
"Were you this explosive even as a child, Bakugou-kun?" Uraraka asked in amazement, all the girls were in awe at the cute (yet still arrogant and obnoxious) child that was Bakugou Katsuki.
"Pretty much," Midoriya murmured as he picked up both trays of food and walking outside the building to eat alone in peace.
"He… He looks like a doting father!" Uraraka cried, Iida couldn't help but agree.
"Reminds me of my brother and I when we were younger," Iida smiled, wiping a tear from his eyes. Todoroki looked at the two crying figures by his side and back at Midoriya and Bakugou.
"Cute…"
"Alright… so the kid is between the ages of 11 to 13, he must attend a school near Bakugou's neighborhood. Golden eyes, thick black framed glasses and chocolate brown hair," the principle smiled at the heroes around his table. Everyone nodded, taking off immediately to attempt to find the boy who had made Bakugou a child. "Oh, he also has a dog named Kacchan!" All Might blinked and then slightly giggled.
"Kacchan… the dog?" Aizawa asked and the principle nodded. All Might and Aizawa broke down laughing, not believing it.
"No wonder young Bakugou got mad! A dog is named after him!" All Might laughed and Aizawa coughed to stop his laughter, something seen very rarely.
"He had it coming," was all he said and the two took off. Midnight and Aizawa were taken to middle schools, other heroes focused on primary schools.
"It seems like this is Bakugou's and Midoriya's old middle school, he may be a first year here," Midnight said thoughtfully as she walked ahead of Aizawa. Three of the one they had tried before were a failure and two of the primary schools as well. The principal quickly allowed all the first years to gather in the gymnasium to be seen. It was Aizawa that caught sight of the kid.
"Midnight, it's him," the three walked towards a small and pale child with chocolate brown hair and golden eyes wearing thick framed glasses. The kid looked up at the two teachers in slight surprised. "You, what's your name?" students began to whisper around him, the boy looked down.
"Hyuuga, Kyoya," the boy replied.
"Do you have a dog named Kacchan, Hyuuga-kun?" the boy bit his lip, but nodded. The two teachers looked at each other and nodded.
"You will have to come with us," Aizawa announced and the kid just sighed and nodded once more, following the two heroes out of the school, with his father informed about the situation he was now in UA. In front of him, that annoyance of Bakugou Katsuki.
"You! It was you!" Bakugou fused and the kid stared at him annoyed.
"You were the one acting like a child!" Hyuuga fought back annoyed. "It's only fair you go back to that." The teachers repressed their giggles at the scenario before them.
"While it is true that Bakugou was most likely being a nuisance, you should know by now that the use of your quirk without a license and in public is prohibited. Hyuuga looked away and nodded.
"I understand, but he also kept pushing my dog's buttons and I didn't want my dog to bite him, he's a good boy but hates people…" Hyuuga bit his lip. "I think it was the best way to avoid conflict since Kacchan likes children…" Aizawa nodded understandingly. The kid only wanted to avoid his dog biting Bakugou and put his quirk to use since it would be the safest way for his dog to stay calm and none of the two to be hurt. Aizawa put his hand on the child's head and ruffled his hair.
"You cared for both your dog's and Bakugou's safety, your reaction was good but you should've returned him to his normal form after.
"I can't,"
"What do you mean?"
"My twin is the one that makes them age… I make them younger… that is our quirk," the kid began to sweat nervously. "My twin is currently vacationing with my mom in South Korea since one of their favorite bands is having a concert, they won't be back until the end on the month," Midnight took a look at the calendar, it was a week before the month was over.
"You've got to be kidding me…" Bakugou looked enraged, although in child form, he didn't look as bad as his usual self.
"Well, we'll have to wait until his brother returns… 'till then… you will be staying here in UA!" Midnight announced. Bakugou was speechless. The child pushed up his glasses.
"Sorry, Kacchan," the boy gave a side smirk.
"You bastard!" Bakugou yelled enraged but Midoriya was able to grab him back from attacking the boy. Midoriya kept Bakugou in a bear hug as Hyuuga left. His quirk was truly… fascinating, he wondered… how it would look in action, and how it activated and to have a power that correlates with someone else? So his twin could make them much older! Fascinating. "Stop thinking they have incredible quirks you bastard Deku!" Bakugou seemed on the verge of tears.
"AAHH! Sorry Kacchan!" Midoriya apologized as he cleaned his eyes with a handkerchief. Midnight and Aizawa stared.
Midoriya! You're like a doting father! Midnight squealed and Aizawa coughed in surprise. As Hyuuga left campus, none other than All Might stood before him. Hyuuga's eyes became wide.
"ALL MIGHT!" the child said in pure disbelief.
"That's right young man! It is I, All Might~!" the hero laughed loudly, the kid's eyes widened from excitement. "I've heard of what you did to one of our young heroes as well," the kid's eyes quickly fell to the ground.
"I'm sorry…" Hyuuga apologized silently.
"I understand our young Bakugou was at fault here as well so don't feel too bad about it, it can be a lesson to you both," All Might kneeled before the kid. "That quirk of yours is truly amazing, I hope you work hard to become a hero here in UA as well!" Hyuuga smiled brightly.
"I am not as strong compared to my brother… but I will try hard to get in as well!" All Might stood up and ruffled the kid's hair just like how Aizawa had earlier.
"Take care young man!" Hyuuga was then escorted out by security and returned to his school, now Bakugou had to wait until the end of the month to return to normal.
"Ah Kyoya… I got the call from the school today, you went head on with a UA student," Hyuuga's father looked worried as he looked at his son who let go of their large dog.
"I'm sorry dad… I was also suspended for using my quirk…" the father only shook his head but smiled fondly.
"You still took care of Kacchan though, and your suspension is only two days so not too bad!" the father smiled. "I talked with your mother and she said they'll still be back by the end of the month and laughed about the whole fiasco, both her and Kyo were proud of you for caring for Kacchan."
"Ah, talking about Kacchan, I'll go on a walk with him right now!"
"Alright be back for dinner, and don't turn anyone else into a child!"
Hyuuga put the leash on his dog and off outside they went, crossing none other than Midoriya as he exited his home. Hyuuga quickly recognized the young man from the sports festival.
"Midoriya, Izuku," Hyuuga pushed his glasses up, his dog seemed to take a liking to young Midoriya since he didn't growl or bark at him even though he was a stranger.
"Eh, you know me?" Midoriya asked surprised. Hyuuga scratched the back of his head.
"Of course you're the really cool hero at UA!"
Cool hero…? Midoriya's face flush, someone thought he was a cool hero~
"Well thank you so much for the compliment," Midoriya smiled widely, the kid nodded, his face red.
"Um do you need something though?" Hyuuga asked, Midoriya nodded.
"I Just wanted to say thank you, since thanks to you, I'm able to spend time with Kacchan once more! Also, your quirk sure is amazing!"
"Thank you! I think your quirk is mysterious but very amazing as well! I hope you become the next Number 1!" Hyuuga blushed to his ears. "I want to be a hero as well… when I do, please take care of my brother and I, since we both admire you!" Midoriya felt like he was going to die. Someone… someone actually looked up to him?! He breathed in and smiled.
"Work hard, young man," Midoriya gave him a thumbs-up. Hyuuga smiled brightly and his dog began wagging his tail, he couldn't help but notice that… the dog resembled Kacchan! He really did! He said goodbye and turned back towards UA, having been assigned Bakugou's guardian for the time being, having picked up clothing his mother had prepared only.
This was going to be a long week. School was going to be hectic and Hyuuga's twin returned a week from that day, Monday.
I'm having too much fun with all these ideas flowing through my head! Freaking Bakugou pissed off some kid younger and now he's a child! With Midoriya in charge of kid Bakugou, how will their week turn out!
