Chapter Text
It starts like this, a test, simple with simple questions but with the expectations of complex answers.
Not hard. Simple but complex and routine.
Students write their answers hoping that their answers will be worthy to get them accepted into the highschools of their choices. After all tests like this were essential to a bright future, and each needed to be answered to attract the right crowd.
"The hell is this!?"
A loud exclaimed voice of blonde hair, vermillion red eyes and explosives roared in the classroom.
"Quiet, Mr. Bakugou."
A tired looking teacher chastised the teen, Bakugou's glare doesn't let up and he sneered.
"What the hell kinda question is this!?"
He asked vehemently pointing at the question on the section of the page, the teacher strolled towards the bomber's desk with narrowed eyes and sighed softly.
"It's a simple question Bakugou."
"Wrong. It's a stupid question. What idiot asks about what would I do if something happens to my clothes? That's nothing hero related!"
Bakugou pointed out, annoyed, the teacher sighed again nodding her head.
"Be it as it may, you still have to answer the question."
The teen wanted to protest. He really did. But the glare his teacher was giving him–challenging him to disrupt the class with another explosive tantrum–stopped Katsuki in his place. The blonde knew full well what would happen if he was kicked out of the classroom during this test.
After all, this test was what determined whether he could attend U.A. high school.
Something Katsuki's dreamed of since his younger years as a child who looked at crime fighting movies and news of All Might, childlike wonder turning into sheer determination and hard work to control his quirk, years old training to be a hero in the making lead him to this final point.
This test.
Then finally, he'd be off into the big leagues fighting real villains with real heroes and becoming the number 1 hero.
That was the plan since day 1 of him getting his quirk at five years old.
But now…
Now Bakugou's glancing down at one question, a simple question that has him stumped, one that took him aback.
What would you do when your hero costumes keep getting messed up?
It was this question that had Katsuki violently gripping his pen, hitting down a simple but expressive answer.
What shitty question is this? If my costume keeps getting messed up then I'll just make my own damn clothes!
And that's how Bakugou Katsuki finds himself with a scholarship to attend the Support Course at U.A., wild blonde spikes going everywhere stick out making him look like a Pomeranian, his nasty scowl doesn't leave much of the image either as he marches down the halls of the prestigious school.
Red glare directed themselves at everyone who he passed. "The hell you shitty extras lookin' at?!" he snarled menacingly, daring the extras to say some shit that would result in a famous tongue-gun lashing and some explosives.
They all turn away. Some walked quicker than most to avoid the blonde and all his ire. Bakugou tsked.
'Fuckin' cowards.'
He mentally cursed at their spinelessness, disgustedly disappointed by the lack of backbone the students of the seemingly unbeatable and famous school had, it reminded the teen of his weak middle school years, something he flinched at.
The reminder of the school and their quirksest mindsets sickened Bakugou, he being a victim of teacher's praise and egotistical assumptions of him becoming a powerful hero all because of his flashy quirk, meanwhile students with weak quirks or no quirks at all were looked down upon and ridiculed, one he remembered being the main target to all, including himself.
Bakugou shakes his head discarding the memory of the unfair system, he inhaled then exhaled harshly, mentally reminding himself that he wasn't there and that he was going to be a kickass Support Hero.
With a curt nod Bakugou puffer up his chest and continued on marching forward, right hand gripped the sticky note labeled 1–H tight with newfound confidence, searching for the classroom where he would spend three long semesters of trial and error becoming the #1 student.
BOOM!!!
An explosion erupts and an incoming blur of blue, black and pink comes flying at Katsuki "What the hell!?" He cried out loudly when the image of a pink haired girl with green-yellow eyes came into view, he notes that she's wearing the UA uniform albeit with some gloves and a pair of inventor goggles.
"Wow, that was close." The girl looked up smiling "Thanks for the save, spikes"
"Oi, the hell do you think you–"
"HATSUME!!!"
Whatever Bakugou wanted to say was stopped when the loud sound of footsteps erupted, the thumping was robotic, like some type of machine was coming out and Katsuki didn't know whether to leave the girl or use his quirk.
He does neither when a pissed off person comes through the door.
Well at least from the man's tone he was pissed, Bakugou couldn't really tell since the guy practically had a large yellow helmet that resembled a excavator claw covering his face, the lower part of the helmet was long with a jaw guard, he was short, shirtless and wore gray fingerless attached to gloves metal guards that extended down his arms, his hair was spiky, long and ginger.
"What have I told you about being careful while tampering with the equipment inside the lab? This is the fourth time you've wrecked the room with your experiments!"
"B-but sensei it wasn't my fault!"
The girl–Hatsume said I'm defense, the male folded his arms over his chest and cocked his hip to the right.
"Really?" he didn't sound like he believed her "And whose fault do you think it was? You and I are the only ones who use the lab on a daily basis, so do tell me who caused this explosion if it wasn't you?"
he asked in a tone that was either indulging or bemused, Hatsume beamed brightly at her teacher's question and looked at Katsuki.
"Would you believe me if I said it was this guy?"
Bakugou promptly drops her, Hatsume hisses at her but hits the floor harshly.
"Ouch, what was that for!?"
The girl looked up at Bakugou with a hurt look, he glowered at her with annoyance.
"Obviously that's for lying, stupid!"
"Okay but you didn't have to drop me."
"Actually I did, since I don't even know you and you suddenly flew into my arms like some crazy woman."
The girl blinked, she blinked again then beams brightly "Awwww hear that Powerloader-sensei, he called me a woman~"
The short man snorts.
"More like a spawn of hell out to destroy my lab." he turned his head to Bakugou "And who might you be, if you don't mind me asking?" he asked with curiosity in his voice, Katsuki bristled.
"Bakugou."
"Bakugou huh? And you're here because–"
Okay so Katsuki may've scowled at the lack of understanding Power loader had for him being here, but he holds back a scoff and says.
"I got a scholarship to work in the support department."
"Ah yes you're the newbie who I've been informed about." Power loader chimed as if recognizing Bakugou, the construction looking hero pulled off his helmet revealing a handsome youthful face paired with dull slanted blue eyes and a long mouth.
"My name's Power loader, I am head of the support department as well as your teacher."
"Power loader" Katsuki repeated voice, tongue-tied, unusually unsure of himself.
"I know it's a mouthful but I feel like you'll get used to it, at least in time."
Power loader chuckled, noticing the confused look on the teenager's face.
Bakugou nodded "Right, okay then."
"So Bakugou was it?"
The boy nods "I was informed that you have quite the observation skills and scored beautifully on the written assessment test. You even figured out how the robots worked earlier than the rest of your group, correct?"
A shrug "I guess. Shit was easy, a kid could understand if they actually paid attention to the whole thing."
Power loader smirked.
"Are you implying that you're sharp?"
"I'm implying that I pay attention, and I don't like being dragged behind by shitty extras who can't play the game."
Power loader nodded "Hmm. Interesting notion, a little harsh but understable. So you like a challenge?" he asked, brow raised in question.
"Hell yeah, give me all you've got and I'll meet it head on" He says, his competitive nature coming out for a split second, Bakugou smirking with challenge.
"Hey Power loader-sensei, got a minute?"
Bakugou turned his head to see two males; a boy with long blonde hair tied in a ponytail and bright blue eyes and a dark blue haired boy with dark eyes standing in the doorway, the blonde was big, buff and had this stupid grin on his face whereas the bluenette looked like he wanted to be anywhere but here his gaze to the floor in timidness.
"Ah you're just in time Mirio, Amajiki, come here for a sec."
Power loader smirked brightly at the two males who entered the lab, both approaching the redhead.
"Gentlemen, this is Bakugou."
Mirio and Amajiki look at Katsuki.
"Starting today he will be tasked with analyzing and figuring out a way for you to use your quirks without damaging your costumes."
The two turn and look at Bakugou.
"Isn't he a freshman, don't newbies in your course start off with the basics of hero tech?"
"They usually do but Bakugou here said he wanted a challenge, and I'm giving him one."
The ginger haired man admitted.
"But don't you think having a newbie analyzing us is a bit advanced?"
The blue haired boy asked with curiosity.
The blonde haired teen asked with a skeptical expression, it made Bakugou bristle, the spiky haired blonde opening his mouth ready to chew the blue eyed boy out, but Powerloader was already talking.
"I wouldn't judge a book by its cover Mirio."
Power loader tells the blue-eyed teen.
"Bakugou here was recommended to join the support department on a scholarship, bit.to mention he passed the hero assessment entrance exams with flying colors, which were mostly due to his observation skills."
"Really? Both tests?"
Amajiki looked surprised by Bakugou's feat, Power loader nodded "Yup and now he'll be working with you." He smirked, placing a power clawed hand over Katsuki's shoulder "I expect a thorough report from you in an hour, until then feel free to use whatever you like and do try not to overexert yourself. Good luck."
With that Katsuki finds himself alone with two other first year students, Mirio and Amajiki silent, awkwardly standing in the doorway unmoving, the blonde tsked.
"Well." Bakugou's voice growled alerting the two to his glare "Are you gonna come over and tell me what your crappy quirks are? Or would you prefer just standing there looking like dumbasses?"
Mirio's eyes narrowed a bit at the insult, but he took a step forward, approaching.
"Alright, guess I'll go first."
Bakugou assesses the tall blonde boy, red eyes giving Mirio a once-over, bidding curtly.
"Sit down and let's get this shit over with."
Obeying albeit carefully, Mirio does as he is told and Bakugou follows suit, Amajiki stands watching from his spot by the door.
"So what exactly do you need done on your costume? What are your main concerns?" Bakugou asked, getting straight to the point, professional and all focused–having parents in the fashion industry taught him to be forward and blunt, something that was key to success.
Mirio blinked "W-what?" he blinked at Katsuki's change in demeanor, the spiky haired teen's eyes narrowed, teeth bared.
"Your costume, what do you need done with it?"
Katsuki repeated, tone snappish, Mirio let out a small 'oh', sheepishly taking out a small piece of paper from his pants pocket that had a design of his costume.
It's a white skin-tight top with the golden number 1000000 in the center, the pants are blue and the boots are white and knee-high, there's also a cape that is messily colored red, all in one it's not a poor sketch of the blonde's costume.
"I'm having some trouble keeping my costume on my body."
Bakugou blinked "Keeping your costume on?" He gave Mirio a confused look, the older boy chuckled then nodded.
"Yeah, you see my quirk is Permeation and sometimes when I use it I phase through objects, people, the floor I even go through other surfaces but when I do, my clothes come off so I end up naked."
He sighed softly, a look of annoyance plastered on his youthful face with this look of reminiscing about the times he ended up being naked due to his quirk. "It's a real pain, and I really want to fight villains without fearing that my quirk will make me accidentally phase out of my clothes."
Bakugou nodded "I see." he says with a far-off expression glancing at the drawing.
"So I was thinking that maybe you could alter my costume in a way that allows me to move without it coming off."
Mirio finished explaining what he wanted or at least hoped the younger teen would help him accomplish, Bakugou hummed gruffly, thoughtfully, red eyes narrowed in thought.
"Sounds like you have a lot of shitty annoyances to your quirk."
Katsuki finally concludes without hesitation after mentally processing everything.
"Hey you shouldn't say it like that?"
Mirio says, affronted with indignation.
"Why, it's true? For one thing, if you're incapable of moving or standing still without phasing through things, which is a big issue in itself. There's also the fact that your crappy outfit will fall off regardless of how many silks, fibers and fabrics I can think of that will suit you–actually no scratch that. Even with those choices that won't guarantee that your costume will stay on, after all your quirk is Permeation."
Bakugou looked back at Mirio "Have you ever considered actually using something useful and similar to your quirk? Something that does follow you when you accidentally go through things?"
Mirio cocked his head to the side and hummed in consideration to the question, blue eyes focused and eyebrows furrowed.
"To be honest, I'm not sure." He shakes his head "I mean when I phase through things it's unexpected, and when I use my quirk in a fight it's the same thing, I go through my clothes, I can't think of anything that stays."
"Uh huh alright I see it now, c'mere for a sec." Bakugou crooked his finger at Mirio beckoning the buff teen over, the older boy approached looking confused.
"What's wrong?"
"Nothing, just shut up and bend down?"
"Why?"
"Because I wanna see something, dammit, it's vital to solving your shitty issue."
"Oh okay." Mirio awkwardly bends down now he is almost nose to nose with Bakugou compared to having the other barely up to his wide shoulders "Is this okay?" he asked the spiky haired boy with red eyes.
Bakugou grinned "Perfect~" Mirio blinked at him "What exactly are you–yowch!"
The buff blonde yelped when the younger suddenly plucked a strand from his golden hair!
"Yes this will do."
Katsuki crooned with an appraising nod as he held the long strand of hair in between his pointer and thumb finger, the third year gaped at him.
"What do you think you're doing?!"
he asked, completely confused and in disbelief that some guy he barely knew plucked a strand of hair right out of his head.
"I thought it was obvious that I'm working on your quirk problem."
Bakugou said, walking towards the tables in the lab and placing the strand down.
"Okay but why did you pull out some of my hair!?" Mirio asked with wide eyes making him resemble a kicked puppy.
"Use your head, why did you even come here? To get your crappy costume fixed, and I'm helping you make that possible."
"I don't follow."
"Then let me dumb it down. Your quirk allows you to phase through things. Shit goes through including your clothes which leaves you exposed. I took this piece of your hair because it's part of you which means it's part of your quirk since it's the entirety of your person, get the picture?"
Mirio nodded "I think so, yeah." his eyes widened "So you're saying that adding my hair sample in my costume will make it capable of staying on me even if I phase through things?" he asked in realization.
Bakugou grinned "Exactly, since your hair is part of you and remains intact when you use your quirk, it can be a key factor in making your costume. If that's the case then maybe I can use strands of your hair–with permission this time, to infuse them into the fibers in your costume so that it'll be capable of staying on." he says picking up the strand that glistened in the light of the lab.
"Almost like a second skin."
Mirio interjected excitedly.
Katsuki shrugged "Almost, I'll have to check it out to be safe. It could take a few hours since quirks like yours are a bitch to handle. But, I'm confident that it'll work enough to prevent your ass from getting exposed." he told the blonde.
"Still if there's a chance that my hair can be used to fuse with my costume so that it'll keep my costume from falling off each time I use my quirk, then I'll take that chance"
Mirio was grinning brightly, stupidly looking all optimistic, Katsuki could see the glimmer of hope in those blue eyes and flinched at how shiny the older boy got, he fights back a retort still observing the older.
"May I offer a suggestion?"
Mirio nodded "You're the one who's modifying my hero costume, make all the suggestions you want."
Katsuki snorted, his eyes narrowed "Aside from your silly costume falling off you when you phase through things, are you able to get a sense of your surroundings beforehand? Permeation means that you'll be able to go through things but you'll be weak using your instincts. If that's the case then maybe you should consider having something attached to you modified with fibers from your hair that will phase through things with you, a tracker or something small and can't be easily detected."
The teen continued analyzing Mirio from head to toe.
"Togata wears a visor, maybe you can do something to it that acts as a scanner or A.I. that informs him on the things going on around him, that way when he uses his quirk he will know who's around and won't risk detection so easily."
Bakugou and Mirio both look at Amajiki.
"W-what?" The blue haired teen asked with weariness "Tamaki, you just said something amazingly brilliant!" Mirio said with bright sparkling eyes at the other boy.
"I did?" Amajiki blinked confusedly, nervous with a jittery look on his face.
"You actually did, the idea on the visor is perfect and you seem to know more than you let on, why aren't you in hero support?"
Amajiki flushed red "W-well I...I didn't think I'd be good in support." his shy gaze shifted slightly towards Katsuki and Mirio, then lowering to the floor "And...I gu-g...guess I wanted to be a hero, like Togata." he answered truthfully, modestly.
"Pfft. That's lame." Bakugou groused, unashamed and blunt at the blunette.
"Hey don't be mean to Tamaki." Mirio lightly chastised the younger with a frown.
"Not mean, honest." Katsuki shoots back.
"You're calling him lame for wanting to be a hero."
"No, I'm calling him lame because he rather follow your Johnny Bravo looking ass than use his observation skills."
"Johnny what now, who's that?"
Bakugou let out the most dramatic gasp, "I know you didn't just ask who Johnny Bravo is. You uncultured swine, did you not have a childhood? Johnny Bravo is legit the equivalent to you! But broader and buff."
Mirio still looked lost. "Uh...what?"
Bakugou groaned loudly, shaking his head at them "No way I can't– you deadass don't know who Johnny Bravo is? Nope I refuse to accept this. This is blasphemy! Aren't U.A. students supposed to be know-it-alls and learn everything including old TV shows!?"
"If it makes you feel better, we watched Power Puff Girls."
Amajiki says as a matter of factly.
"It's not the same! They're kick-ass but seriously y'all never watched Johnny Bravo? Y'all ain't human. Nope y'all worse than humans, y'all worms hiding under a rock and I can't let this slide!"
He was so horrified by this newfound information that he didn't even hear Powerloader and Hatsume return to the lab.
"I see you're handling things well."
"Ah, Power loader-sensei."
Mirio chimed in greeting the short pro hero, the ginger haired man walked towards the three boys with Hatsume following, He looked at Ethan, then at both Amajiki and Mirio.
"So, was he able to help you with your costume modifications?"
Mirio grinned "He sure was! In fact he had this idea of adding fibers to it so that it will phase through things with me! He even plucked a strand out of my head"
Power loader's eyes widened slightly "Is that so?" He looked at Bakugou, "You were able to grab a sample of his hair?"
Katsuki nodded "I was, figured taking one would benefit explaining the theory that adding a sample of the ghostie's–Katsuki ignored Mirio's affronted 'ghostie'–hair could be used in making specialized fibers that are suited for his quirk, though I didn't start with his costume yet, I managed to get the gist of how it should be."
The teen jutted a finger at Amajiki "He also added some useful input on adding an A.I. into ghostie's visor so that it can inform him of his surroundings–that's if this information is approved by you, since this was a test for me to modify both of their costumes. Blue also admitted that he only came as a tagalong for ghostie."
"I see."
Power loader's expression is still unreadable "Hatsume."
"Yes sensei?"
"Show Bakugou where the tools are to make the fibers, also give him a quick tour of the lab and show him where he'll be assigned."
The man instructed the pink haired girl, Katsuki arched a light brow "Does this mean–" Powerloader nodded, answering the teen's question without finishing.
"Yeah, you passed."
Bakugou let out a loud triumphant cry, startling those around who witnessed the tiny explosions pop in his hands due to his quirk, the spiky haired boy canceled his activated abilities.
"Sorry." he grumbled "Shit goes off with my emotions." Was the added information.
"Ah so Mei was right when she said you were the cause of the earlier explosion."
Power loader's tone is teasing, amused, Bakugou tenses when the man's hand ruffles his hair "Guess we'll have to make you something to help keep those explosives from activating when you get like this, now won't we?"
"Stop it."
Katsuki gruffed lightly pushing the man's clawed hand away from his head, the ginger haired hero snickered "You did good on your first task, I expect you to be done with the modifications no later than tomorrow morning, Hatsume will assist you in that time so use your time wisely and don't dilly-dally. I will be back with your schedule and a spare key to the lab."
He smirks again then leaves the lab, Katsuki feels both annoyed by the teasing of his new teacher but also pride swell in his chest at his accomplishment, he jumps when Mei's slender arm slings over his shoulder and her grinning face is in his sights.
"Look at you already getting approved by our teacher, you're just a little genius aren't you Bakugou~"
"Get off me, crazy chick."
"The name's Hatsume and starting today I'm your classmate, so treat me nicely."
The pinkette chimed sweet and playful, Bakugou bristled at the girl.
"Like hell I'd treat you nicely, let go of me you damn annoying octopus!"
As the blonde tried getting away from Hatsume, Mirio and Amajiki stared amusedly, the blue eyed blonde smiling big.
"Well for everything that's happened so far, Welcome to U.A. Bakugou, I hope we can do this again."
Bakugou stopped struggling in Mei's grasp, looking at Mirio with a small glare.
"I guess, you better not have another shitty issue with your costume after this, ghostie." he says with a small smirk.
Mirio laughed lightly now. "Hey if you're confident that my costume will come out good and doesn't fall off when I'm fighting, then it's all good, we'll just have to see."
"Yeah and when I fix your costume you better tell the other extras about my awesomeness."
Bakugou added to the older boy who smirked back.
"You got it."
Mei giggled ruffling soft blond spikes "Good to have you here, welcome to the Support Department, let's do our best!."
"I'll do my best after you let of of me!" Katsuki says still attempting but failing to break loose of Hatsume.
"Hmm, how about no? Besides I've always wanted to have a freshman, let's make cute babies together~"
Bakugou finally broke free "Oh hell no, I ain't making any brats with a nut job like you!" he says running out and away from the pinkette.
"I didn't mean literally!"
Hatsume shouted running after him.
"Don't care, get your creepy ass away from me!"
Oh yeah coming here on recommendations for his response on a test wasn't really the plan Bakugou was going for, but he secretly doesn't regret his decision.
The Support Department was cooler than the hero course anyway, Bakugou would make sure everyone knew who he was and did by the end of the month.
