Prologue

The Incident

Wednesday, January 8

 

It was known as the Shussei-Ryoku Incident that changed the way people viewed the stereotypical roles gender played into society.  Sure, there were outliers of people who believed gender stereotypes were complete horse shit, but a majority believed males and females at least had a certain role to play due to what was between their legs. Man works to provide for his family, while the woman helps rearing children.  

 

But this society was already shaken up before by the emergence of quirks.  Superhuman traits gave way to spectacular powers of levitation, strength, or a variety of abilities as well as mutation of body parts of different skin color, additional limbs, or lack of limbs.  Quirks really did just throw human and animal DNA into a blender and voilà—a new era of what was normal came forth.  It also changed human DNA enough to where it was difficult to reproduce, which is where many companies popped up to fulfill the need for cute, chubby babies.  

 

Shussei-Ryoku was one of these pharmaceutical companies that worked with scientists to create a fertility treatment to help boost Japan’s declining population.  They managed to find some clueless, gullible person with a hyper-fertility quirk and convince the poor soul that what he/she was doing was saving Japan from collapse, and helping millions of childless couples have children. Said person was paid handsomely for their rights to his/her DNA and never to be heard from again.  Various human and animal DNA were also taken from unorthodox places and combined. 

 

In the beginning, Shussei-Ryoku had well-intentions to help families; however, as the company grew, so did their unethical practices.  Perhaps it was faulty training or lack of environmental concerns that caused the chemical for hyper-fertility to spill into the drainage systems which then seeped into the water system.  People were bathing in it, drinking it, playing in it.  The hyper-fertility chemical, also known as Abo-2gen (pronounced ah-bō-tū-gen according to media) mostly affected those with hormonal imbalance during puberty or who were taking estrogen/testosterone to better help with fertility treatments.

 

Abo-2gen had already reached nearly everywhere in Japan before scientists found out what had happened.  As typical of a large pharmaceutical company, they covered up the incident hoping no one would notice anything unusual save a slight uptick in pregnancy.  Of course, nothing ever goes as planned.  The Abo-2gen drug mutated.

 

It began affecting males and females in strange ways.  It mattered not if one was male or female—each came with a new set of genitalia that wasn’t there before.  Then there was the behavior characteristic.  Males or females suddenly became hyper-aggressive and ended up getting their partners pregnant.  Others were more subtle than their aggressive counterparts.  These males or females were more empathetic and introverted and ended up getting pregnant by their partners.  Senses were heightened such as smelling scents on people, the sensitivity of touch, taste, sight, and hearing.  Surprisingly, a majority were not affected as drastically as having a second gender, but still had sharp senses.

 

It was too late by then to reverse the side-effects.  All Shussei-Ryoku could do was pray to God that nobody would be the wiser.  Again, nothing ever goes as planned.  A whistleblower notified several pro heroes about the incident and an investigation began, which then got several local reporters sniffing for a good story.

 


 

Chapter 1

News of the Weird

Thursday, March 27



Katsuki Bakugou was running through a dense pine forest somewhere unknown.  It was dark and cold, and he was shivering.  His quirk didn’t work in this place for whatever reason.  Fallen trees and thick bushes blocked his way.  “Fuck,” Katsuki thought, as he was huffing, jumping over a small cliff nearly tripping on landing.  He was running towards something, he believed.  Or was he being chased?  It was never clear to him.  All that he knew was that he was running out of time.  A cold dread was creeping into his soul.  Something somewhere in this shitty forest had answers for him, and he needed to find out now before he goes mad.  Well, more mad than usual.  Suddenly, he slipped on a patch of mud and leaves slammed into the ground…

 

BEEP.  BEEP. BEEP.  

 

Katsuki awoke with a start.  6:30 a.m.  Ugh .  That same damn dream again.  He couldn’t remember when the dreams began, but they had been recurring amost nightly.  Maybe he was stressed, but for now, it was not a priority.  Katsuki pushed aside the dream, rubbed his eyes, and stretched his arms over his head.  Time for his morning routine: dress into a black tank top and sweatpants, do 15 minutes of stretching, and head outside the UA 2-A dormitory.  

 

Katsuki glanced at his watch—6:50 a.m.  This was his favorite time of the day.  The sky had barely a hint of the morning sun in the horizon with only flickering stars and wind-swept clouds to greet him.  Not many extras were up this early to bother him either.  He took the softly lit path that circled around the campus, passing well-maintained landscapes covered in morning dew, empty benches, beautiful contemporary architectural buildings, and sometimes an occasional student jogging—probably third-years.  Time was precious for them, so getting exercise at odd hours was quite common.  

 

I’ll be a third-year student in less than a month.  Tomorrow will be our last day as second-years.  Time really went by fast.

 

The cool spring morning air did little to help Katsuki from sweating as he rounded the last corner.  Finally reaching the dorms, he grabbed a clean set of his school uniform and toiletries from his room, then headed to the communal showers to rinse off.  Once he finished dressing himself (minus the red tie), he headed to the kitchen to make himself a light breakfast.

 

By this time, other students were already in the kitchen as well.  The quiet avian Tokoyami Fumikage nodded to Katsuki, followed by a yawning Mashirao Ojiro dragging his tail. 

 

“Mornin’ Bakugou,” Mashirao said.  “Want some coffee?  I’ve brewed some and can pour you a cup.”

 

“Sure.”  Mashirao poured a cup and handed it to Katsuki.  He gently blew steam from the cup to cool it off and sniffed the aroma of coffee.  He noticed it smelled a little bit too rich.  “Tails, did you switch brands of coffee?  What brand of coffee are you brewing?  Colombian?  Ethiopian?  Brazilian?  Aroma smells really good. Hm, maybe even Indonesian or Vietnamese?”

 

Mashirao looked at Katsuki curiously then at the bag.  “It’s the convenient store brand I always get.  Like…the cheapest brand.”  Tokoyami chuckled in his corner with a cup of coffee—black of course.

 

“Huh…really?”  Katsuki grabbed the bag and sniffed its contents, thoroughly confused.  Odd.

 

“Good morning everyone! It’s such a glorious morning! Spring has arrived, birds are singing, flowers are blooming, and we are well on our way to becoming third-years!”  Tenya Iida cheerfully proclaimed as he came down with the nerd squad.

 

Ugh, it’s too early to be this cheerful , Katsuki thought.

 

“Right!  Just two more days to finish this term and we’re officially gonna be third-years!  I’m so excited!” Ochaco Uraraka squealed, pumping her fist up and down.

 

“As am I.  I wonder what’s left to teach us since we already completed our work-studies, exams, and assignments for the term, ribbit ,” Tsuyu Asui mentioned as she placed a finger on her lips deep in thought.

 

“Good morning,” Shouto Todoroki said quietly while ignoring the rest of the conversation.  He yawned and headed straight towards the coffee machine.  Todoroki was not a morning person.

 

Finally, the King of the Nerds barged in fumbling with his tie, “Oh! I bet it’s a lecture on what to expect in our final year.  Or maybe a last minute test because it’s not expected, and UA wants to keep us on our toes to make sure to expect the unexpected like in real life?  Kinda like when we were first-years and we all thought that Aizawa would expel one of us and—”

 

Damn nerd never shuts up.   “Oi, shut up and smell this bag Deku.  What do you think of this smell?” Katsuki shoved the bag eagerly into his face to stop his rambling.  “Well?”

 

Izuku was startled a little bit yet grabbed the bag to breathe in the aroma.  “Oh wow, Kacchan!  This smells really good!  Is it imported?”

 

“See Tails, what’d I tell ya?  This is good stuff,” barked Katsuki.

 

Mashirao sighed.  “Doesn’t really smell any different,” he whispered as he poured coffee into a cup and handed it to Katsuki.  He took the cup and took a sip.

 

“Mm…shit tastes even better.”  Katsuki savored the flavor, then downed it quickly.

 

“Kacchan!  That’s hot!” Deku said worryingly.

 

“Whatever dweeb, I can handle hot stuff,” Katsuki sneered at Izuku.

 

“Pfft! Ha! I’m sure you can, Bakugou~ ,” Mina Ashido sing-songed as she came out of the elevator with Eijiro Kirishima, Toru Hagakure, Hanta Sero, and Denki Kaminari.  

 

“Shut up, Pinky!”  Katsuki glared at her.  Mina blew a flirtatious kiss towards Katsuki as he tried to swipe at her.  “Bye hot stuff!  See you in class,” she yelled to Katsuki before he could do anything else.

 

Eijirou laughed at Mina’s antics, then faced Katsuki.  “Come on Bakubro, don’t wanna be late like Kaminari,” while sticking his thumb at Denki.

 

“Hey! I take offense to that. I’m not always late,” Denki said as he was rushing out the common room shoving his notebooks into his schoolbag.  “I’m sometimes on time when I don’t short-circuit my clock.”

 

Hanta placed his arm over Denki’s shoulders.  “Yeah, well it wouldn’t short-circuit if you stop wearing socks in your carpeted room.  Seriously man, static electricity and you don’t mix.  How many times have you replaced your clock?”

 

“Lost count.  Besides, my feet get cold in winter,” Denki said as he shoved Hanta’s arm and hefted his schoolbag on his shoulders.

 

By now, Katsuki was leaving the stooges behind so he wouldn’t be late to class.  He didn’t bother to listen to whatever they were talking about. 

 

“Kacchan, wait for me!”

 

Sigh .  “Not gonna wait.  You walk too slow with your short legs, Deku.”

 

“Kacchan that’s mean.  I’m not that short.  I’ve grown several inches this year,” Izuku said pridefully.

 

Katsuki glanced back without stopping.  “Ha…more like you grew several inches sideways.  Most of it from your fat ass!”  Katsuki howled in laughter.  Sure, he apologized for bullying Izuku years ago, but they’ve grown close enough to where he could tease him without malice.

 

Izuku blushed at the comment.  However, the little nerd had grown a spine over the years too.  He twisted his backside towards Katsuki, “Kacchan, how do you know this?  Have you been staring at my ass all this time?” 

 

Katsuki suddenly stopped in his tracks and turned around with wide eyes and blushed in embarrassment.  “The fuck, Deku!?”

 

Izuku laughed as he quickly ran past Katsuki out of the 2-A dorm building.  “Looks like you’re gonna be late Kacchan~!”  

 

Snorts and giggles erupted from the kitchen.

  

Tch, fuck off,” Katsuki said as he flipped his middle finger and left the dorms to head to class.  Damn, his morning did not start off well.  Hopefully the morning classes would go by fast so he can blow shit up in the afternoon classes.

 

Katsuki made it to homeroom with enough time to spare.  He spotted Izuku already taking his notebook and pencil out while noticing his stupid smirk.

 

“The fuck you smirking for, stupid Deku? Think you’re real funny shit, huh,” Katsuki huffed as he stood in front of his desk.  Izuku and Katsuki were finally comfortable enough with the bantering between them.  Still, the blonde didn’t take shit from Izuku lying down.  He still had a reputation to maintain.

 

“Yup, something funny alright.  Anyway, I actually was going to ask you something before you called me a fat ass, which is pure muscle by the way,” Izuku nonchalantly said as he opened his notebook.

 

“Hardly.”

 

“That’s beside the point.  What do you have scheduled after the last day of school?  There’s two weeks we have off before we begin school April 14th.  I was hoping we could use UA’s gym facilities to continue training.  We can use the weightlifting room on Mondays and Wednesdays, then track Tuesdays and Thursdays.  Oh! And Friday we can use Ground Beta for quirk sparring.  They allow incoming third-years access to all facilities from 9am to 9pm.  All you gotta do is get the form signed by your parents and turn it in on Friday,“ Izuku rambled as he wrote down a schedule in his notebook.

 

Normally, Katsuki would roll his eyes and tell Izuku to shut up, but even he was kinda excited for training his quirk in top-of-line UA facilities.  This was something he could look forward to.  “You got an extra form?”

 

Izuku smiled and pulled out a sheet from his backpack.  He handed the form to Katsuki.

 

“Oh, are you guys gonna train those weeks?  Maybe I should sign up for it too,” Eijirou said, sliding into the conversation.  “I want to work more on my stamina and lift more weights,” the redhead said as he flexed his biceps and flashed a toothy smile.

 

“Seriously,” Hanta said as he pulled up a chair next to the group, “More weights?  You’re built like a firetruck and look like you could bench press Sato.”

 

Or Deku’s fat ass… Katsuki smirked at the thought.

 

“Haha…yeah, but I feel like if I don’t push myself, I’ll fall behind these two,” Eijirou said, pointing at Izuku and Katsuki.

 

“No way, Kirishima!  You’ve worked so hard on getting stronger, and it shows!”  Izuku proclaimed.

 

“That’s not a bad idea, though, Midoriya,” said Kyoka Jirou.  “I think we all should sign up for training.  I still struggle to do the fireman’s carry technique and need to get better in case of disasters,” the ravenette explained.  “I may not have muscles-on-muscles like Kirishima, Shoji, or Sato, but I want to be able to carry my own weight as a hero,” Jirou said as she flexed her arms.

 

Izuku’s eyes grew bigger.  “Really?  I can get the whole class forms and we can all train together!  It will be fun!”

 

“Great.  Might as well invite 2-B class while we’re at it, Deku.  Hell, just throw in support class, business class, and general class and it’ll be like school never ended,” Katsuki scowled.  Izuku and the others laughed at his snarky comment.

 

“Okay class, settle down,” Shouta Aizawa said as he walked into 2-A’s homeroom.  He was 2-A’s homeroom teacher instead of this year’s 1-A due to the craziness of what they all went through in their first year.  After everything eventually settled, the students couldn’t imagine anyone else being their homeroom teacher.  Many students begged him to follow them to 2-A; fat tears poured from Izuku and Ochaco’s round eyes, threatening to drown homeroom.  Katsuki even admitted out loud to the whole class that it would be ‘Cool if Aizawa was our sensei again’.  That pretty much cemented his decision to follow the class to their second and third-year—not that he would admit it.  UA even went so far as to change the rules: that all the first-years homeroom teacher, whether it be hero class, support, business, or general, will be with them until their final year.  The nice, fat raise thrown at him by UA administration to deal with the ‘problem class’ was just icing on the cake.   

 

Momo Yaoyorozu raised her hand.

 

“Yes, Yaoyorozu?” 

 

She shifted nervously on her seat, yet did not hesitate to ask the question burning on everyone’s mind.  “Aizawa, many of us were wondering what we will be doing these last two days despite finishing all our assignments and work-study.  Not that there’s nothing left to learn, but just curious as to what we will have only two days of learning before leaving for the break,” she politely asked.

 

Something wicked shined in Aizawa’s eye. “Good question, Yaoyorozu.  While there is always something for you to learn as heroes-in-training, it doesn’t make sense to teach something you may forget in two weeks.”  Aizawa glared at Denki and Mina.

 

Both students sunk further into their seats.

 

“What we will do these last school days is something fun ,” Aizawa said as he grinned evilly.

 

Katsuki crossed his arms and hunched in his seat.   This doesn’t sound good.  Aizawa’s version of fun is totally fucking skewed.

 

“Classes 2-A and 2-B will be helping with the preparations of the third-years’ graduation ceremony and party afterwards on Saturday.  As in, you will work together to make a great impression on the community as well as your peers.  You will be dismissed from the rest of the morning and afternoon classes today and Friday to focus on this task.  Graduation must go on without a hitch.  The party is to serve as a farewell to those who will one day be serving our community, so I expect the best from you all.  Don’t screw it up.  Iida, please pass these papers out to everybody.  This list is what tasks you will need to do.  If there is anything you need that’s not on the list or have any questions, let me or Present Mic know.  Preferably Present Mic.  Delegate the tasks however you see fit.  I really don’t care,” Aizawa said as he yawned and crawled into his puffy, yellow sleeping bag.

 

Aw, fuck.  I was really hoping to blow shit up today, not decorate the gym in frilly shit.

 

Hagakure passed the papers to Katsuki who then passed it over to Izuku.  He looked at the list given: 

 

3rd Year Graduation Ceremony — Location Gym Gamma

  1. Clear out Gym Gamma floor; roll protective mat over floor
  2. Set up chairs in two columns of 10x11 rows 
  3. Set up decorations (balloons, streamers, lights, etc.)
  4. Set up platform and tables on north side for administration
  5. Set up sound system (Present Mic will supervise)

 

3rd Year Graduation Party — Location Gym Delta

  1. Clear out Gym Delta floor; roll protective mat over floor
  2. Set up chairs and round tables (30 tables provided; 8 chairs per table) 240 total for students, staff, & guests  
  3. Store extra chairs (x20) in side room in case more is needed
  4. Set up decorations (balloons, streamers, lights, etc.)
  5. Set up sound equipment on south side (Present Mic will supervise)
  6. Set up tables on the west side for food & drinks (catering will be provided on Saturday)

 

  • Bring water to stay hydrated
  • Gym clothes or work out clothes are permitted to wear
  • Food & drinks will be provided for free
  • Contact Present Mic or Aizawa if assistance is needed 
  • Do not slack off!

 

Katsuki sighed.  Guess it was gonna be a long day today.

 


 

The class soon returned to the dorms to change and met at the common room where Tenya was holding a brief meeting to which tasks fellow classmates were assigned.

 

Kyoka raised her hand, “I think it’s obvious that I’ll work with Present Mic with the sound system.  I have a million questions I’ve been meaning to ask him about being a DJ.”

 

“Good idea Jirou,” Tenya said.

 

“Oh, the rest of us girls are pretty good with decorating.  We can handle that,” Toru volunteered.

 

“Don’t forget about me, mon chéri ,” Aoyama stated.  “Who else can make a room shine like I can?”  Sparkles emitted from Yuga Aoyama as he twirled around.

 

“That’s true, Aoyama.  You can work with the lighting then.  Let’s see, there’s still the grunt work bringing in all the tables and chairs to set up,” Tenya said, adjusting his glasses to look at the paper.

 

“We can handle that,” Rikido Sato offered, pointing at himself and the guys.  Mezo Shoji, Eijirou, and Koji Koda nodded.

 

“That just leaves the rest of us to clean the floor and place mats,” Shouto said as he read the list.  “We need to start first so everyone else can do their tasks.”

 

“Then let’s go before Aizawa yells at us,” Mineta said worryingly as he started to leave the dorms.

 

“Alright everyone! We have our assignments, so let’s work diligently and no horse-playing around.  Our upperclassmen will be counting on us for a memorable graduation,” Tenya said, waving his hands robotically.

 

Katsuki rolled his eyes but followed the class outside to the clearing of both gyms where a few 2-B students were already heading.  He did not want to deal with extras the whole day.

 

Tenya talked briefly to 2-B’s class representative Itsuka Kendo about their plan in splitting tasks.  Fortunately only a few from 2-B followed them to Gym Delta—Ibara Shiozaki, Setsuna Tokage, and Pony Tsunotori went to help the girls with decorations while Reiko Yanagi was to assist Kyoka with the soundsystem.  Sato, Mezo, Koji, and Eijirou decided to split their time with both gyms to move chairs and tables with several members of class 2-B.  

 

Katsuki along with the rest of the group had the glorious task of grabbing gym equipment and placing them in the storage room.  Next, they swept the floor until there was not a speck of dirt.  Large mats were taken out of the storage room, aligned, and rolled out to cover the whole floor to protect it from scuffing shoes and spilt drinks.  By then, the grunt work team already started bringing in tables and chairs.  Katsuki, Izuku, Shouto, and Tenya worked together to set tables in their proper spots while Mashirao, Denki, Mineta, Hanta, and Tokoyami placed chairs around each table. 

 

The decoration team began placing navy-blue satin tablecloths and candlelight centerpieces on tables that were ready, while others were filling up balloons of blue, gold, and white.  Ochaco, Tsunotori, Shiozaki, and Tokage teamed up to set up decorations high up in the ceiling with streamers, colored lights, and navy-blue, white and gold combination of voile sheer fabric draped from the very top.  LED lights were hidden within the fabric to create a beautiful fantasy-like scene.

 

By lunchtime, Aizawa and Kan Sekijiro, the 2-B homeroom teacher, brought takeout from a popular Japanese barbecue restaurant and passed plates and drinks to everyone.  Katsuki, Mina, Denki, Hanta, Eijirou, Izuku, Shouto, and Tenya sat on one of the uncovered tables and plopped down their takeout.

 

“Mmm! All those hours of hard work is totally worth it if we’re getting this for free,” Denki said as he messily dipped a rib into barbecue sauce and popped it into his mouth.”

 

“It’s not worth it if I have to see you eat like a goddamn pig, Pikachu,” Katsuki said glaring at the sauce dripping from Denki’s chin.

 

“Whatever, Bakugou.  You need to live a little.  Get a little dirty!”  Denki slurped meat into his mouth then double-dipped into the sauce.

  

Katsuki grimaced, “That’s just fucking gross.”

 

“Bakugou’s right,” Hanta interjected.  “Never hurts to use a napkin,” as he handed it to Denki.

 

“Oh wow, this is so weird!”  Mina said as she was browsing her phone.

 

Eijirou looked over to Mina’s phone.  “What?  What happened?”

 

“I was reading an article from the Japan Hero News website that sounded like your usual junk conspiracy theory stories, but it linked to the more reputable Japan National News site about a quirk causing people to have aggressive behavior,” Mina said, showing her phone to others.

 

“Oh, I heard about that around early in March.  The unknown quirk had been making people act strangely.  I guess the story finally picked up steam,” Shouto added.

 

Bakugou smirked, “You would be the kind of person reading weird conspiracy shit like that and believing it, right Icy Hot?” 

 

“What do you mean by that?”  A puzzled look showed Shouto’s face.

 

“You thought Deku was All Might’s love-child at one point, so you’d be gullible enough to believe in shit that website spews, duh,” responded Katsuki.

 

Izuku looked at Katsuki with alarm.  “Kacchan!  I never told him you were eavesdropping on us!” Izuku said, embarrassed.  “I’m so sorry Todoroki!”

 

“I bet Bakugou’s second quirk must be Eavesdropping,” Hanta whispered to Denki, both snickering while Izuku continued to apologize to the heterochromatic boy.

 

Oh, shit.  Katsuki needed to steer the conversation quickly.  “Pinky, what’s it say about the quirk?”

 

“Nice save Bakugou.  We’re gonna circle back to that whole love-child conversation, but for now, the quirk apparently changes the behavior of people.  It’s so bad that people who became aggressive ended up hurting friends or family.  They, themselves, can’t explain why their behavior changed.  And no one can pinpoint where the quirk came from, or how they got affected.  Reports say it’s random.”

 

“Ooh! It’s like the invasion of the body-snatchers,” Hanta said as he wiggled his fingers in a creepy manner.

 

“Maybe the start of a zombie apocalypse,” Denki added, talking with his mouth full.

 

“God, I hope not.  Can you imagine Midoriya or Todoroki becoming aggressive, homicidal zombies?  Like, we would have no chance to survive,” Eijirou said.

 

“I don’t know.  If we can survive Bakugou, we can survive homicidal zombies no problem,” Denki declared.

 

“You little fucker!  You wanna die?!  Come on Dunce Face, let’s fucking go,” Katsuki yelled at Denki, pointing his chopsticks at the ditzy blond.

 

Izuku and Eijirou held down Katsuki in his chair before he jumped across to pummel Denki.

 

“Really, Kaminari?  Why ya gotta provoke Bakugou?”  Eijirou managed to hold Katsuki back long enough for Aizawa to come in.

 

“Okay, everyone.  Break ends in 10 minutes so clean up and continue working until 5 pm.  After that, you’re free.   The teachers will lock up once everyone is gone.”  Aizawa glared at Katsuki’s table.  “Please don’t make me regret my decision to leave you all in charge,” he sighed as he left.

 

“So,” Mina turned back to Izuku with a mischievous grin, “What’s this I hear about you being All Might’s love-child?”

 


 

The rest of the day they continued setting up tables and chairs or decorating the gym.  Once school was over, the students headed back to the dorms.

 

“We accomplished a lot today.  Just a few more finishing touches for lighting and decorations and it should be ready by Friday,” Toru told Tenya.

 

“Good work ladies and Aoyama.  Tomorrow will be easier since we can all help with decorating,” Tenya told the class.

 

Katsuki went to get a change of clothes and toiletries to head to the communal showers.  It had been a long day and he wanted to rest before dinnertime.  

 

Several of the boys had the same idea, and a few had finished showering including Izuku who began to dry off next to Katsuki silently.  For some reason, Katsuki kept smelling a nice scent—kind of like a forest on a cool night coming off of Izuku.  Huh…must be his body wash or something.  “Deku, what kind of body wash are you using?  Smells good, like a forest or something,” Katsuki said casually.

 

“Uh, what?” Izuku blushed at the question.  He looked at his body wash.  “Uh…it-it’s…um…3-in-1 Essence Shampoo, Conditioner, & Body Wash.”

 

“Essence?  What kind of lame name for a scent is that?  Well, whatever nerd.  You should stick with that body wash.  Although, I recommend you get separate bottles of shampoo and conditioner that are specifically for curls.  Should work better for that nest on your head,” Katsuki said as he grabbed his shampoo, conditioner, and body wash.  Crap, his sense of smell had been off lately.  First the coffee, now this.  Not that he’ll admit it.

 

“Kacchan’s body wash smells great too!  Like caramelized sugar.  Very sweet,” Izuku said cheerfully.

 

“What the fuck?  My body wash is black pepper and bergamot,” Katsuki replied, showing his body wash to Izuku.  “What’d’ya mean, sweet?”

 

“Oh.  Oh!  Kacchan I didn’t mean sweet, “ Izuku frantically waved his hands in front of his face.  “Your odor is just really strong that I can smell it often.  No-not that you stink!  I meant to say your odor smells good even if it’s everywhere.  I-I mean I’m not saying you don’t bathe enough.  You do, but I can still smell you.  Oh, fucking fuck,” Izuku muttered covering his blushing face with his hands.

 

Katsuki wanted to get angry at Izuku for being fucking weird, but looking at him so flustered and hearing him cuss (which was like spotting a unicorn in the wild) was probably the best thing to happen today. “Heh...loser.  It’s ‘cause the nitroglycerin-like sweat that I smell fucking great.  One more thing I’m better at than you,” Katsuki smirked at Izuku and went to the next available shower stall. 

 

Little did he know, a blushing Izuku stole glances at him as he showered.

 


 

Once Katsuki finished showering and putting his dirty clothes and toiletries in his room, he headed to the common room to relax.  Mashirao and Toru were sitting and chatting with each other on one of the couches, while Mina was browsing Chatter on her phone.  Denki, Eijirou, and Hanta were on the floor pulling out a console and decided which video game to play—Silent Hill or Super Smash Bros.  Sato, Ochaco, Tokoyami, and Tsuyu were cooking in the kitchen for their turn in making dinner for the class.  The rest either sat at the tables by the kitchen, the common room, or were heading down soon.  Izuku finally arrived and spotted Katsuki on the couch.  He decided to sit on the same couch but on the other side…just in case.

 

Sitting on his side of the couch not paying attention to anyone, Katsuki pulled out his phone to read his messages.  Fuck, he had a lot.  He decided to ignore most and focus on the one that gave him the biggest headache first:




Old hag: brat text me when ur out of class

Old hag: so eloquent. i can literally feel the love pouring from your last text ❤️



GEMG Dynamight:  😒 bye




Katsuki put the phone away and got up from the couch.

 

“Where you going Kacchan?” Izuku said from the other side of the couch.

 

“Need to get my form for the UA facilities.  Old hag is swinging by to sign it in twenty,” he said while stretching, showing a bit of abs.  Izuku noticed this wide-eyed and quickly looked the other way.

 

“Th-That’s great!  I’m looking forward to when we can train.  I already turned in my form so our spots are guaranteed!”  Izuku scratched the back of his neck looking at the boys playing Super Smash Bros.

 

Katsuki raised an eyebrow.  Why is he so awkward all of a sudden?   “Yeah, sure.  While I’m waiting for the old hag to arrive, might as well get a head start packing stuff before we leave on Friday.”

 

“I should do that too since we’ll be moving to the third-year dorms.  I heard those dorms are better than ours.  Can’t wait,” Izuku said as he got off the couch.  “I’ll head over there with you.”

 

“Whatever,” Katsuki said as he headed to the elevator with Izuku.  He pressed the button to their level and waited silently.  He noticed Izuku’s reflection of the sliding doors that he was fidgeting nervously.  The hell’s making the nerd so uncomfortable?

 

Before he was about to say anything, the elevator dinged at their level and the doors slid open.  Katsuki headed to his room, while Izuku headed to the one next door.  Koji and Mineta’s rooms were the only other ones on the same floor.  As much as he preferred to have the whole level to himself, his neighbors weren’t too bad.  Koji kept quiet despite an occasional furball pet getting loose.  Mineta was afraid of Katsuki.  And Izuku…well, Katsuki accepted the fact that it was impossible to shake off the nerd anymore.  Besides, Izuku had been growing leaps and bounds into his power.  Katsuki had a proper rival now, so that meant dealing with Izuku every moment.

 

Katsuki began taking out and sorting clothes into piles on his bed.  Fresh clothes on one side, dirty on the other to wash at home.  Then he went through his drawers for any school supplies to stuff into his backpack.  Toiletries were left in a bag by the sink ready for the next day.  All his posters, books, and other miscellaneous items were already stored in boxes near the door.  Only the comforter on the bed was still unpacked until the last day.

 

There was a knock on the door. “Hey Kacchan?”

 

“What nerd?”

 

“Do you have an extra box to spare for my All Might collection?”  Izuku said as he grabbed the hem of his shirt and slowly walked to Katsuki’s bed.

 

“Seriously?  Damn, Deku.  How many figurines you have?”

 

“Ah-a lot,” he said as he scratched his head.  “I kinda collected a bit over the year.”

 

Sigh.  Nerd’s gonna nerd, I guess.  “Fine, let me move some of my stuff around,” Katsuki said as he turned towards his boxes.  “I need to rearrange some items to free a box…you know you’re shit at planning ahead, Deku?  Kinda surprising since you’re so good at analyzing quirks and strategizing that rival most pro heroes, but can’t clean your damn room.”  Katsuki turned around, handing an empty box to Izuku.  “Here, nerd.”

 

“Th-thank you Kacchan!”  Izuku said, nervously grabbing the box.

 

“Yeah whatever,” Katsuki said.  He was about to ask what was going on with the nerd but glanced at his bed, noticing the dirty pile of clothes was messed up.  I don’t remember placing my clothes like that.   Suddenly, Katsuki’s phone chimed.




Old hag: hey i’m at entrance of ur building. bought u n izuku some snacks too



GEMG Dynamight: k comin down




Katsuki took his permission form and pen from his desk completely forgetting all about his dirty clothes pile and headed towards the elevator.

 


 

As Katsuki had left his dorm room, Izuku was leaning against his door having a mini heart attack.  He slid down the door breathing heavily once Izuku knew that Katsuki wasn’t going to barge into his dorm room.  He did not know what came over him to grab Katsuki’s dirty boxers.  Izuku walked into Katsuki’s dorm actually needing a box, but the tantalizing smell of the potent aroma of caramelized sugar from the offending underwear beckoned him.  An inner voice he never knew he had suddenly possessed him and began echoed loudly in his mind— MINE MINE MINE .  

 

Izuku snatched it as fast as possible before Katsuki finished rearranging his stuff.  He placed the boxers behind his back and shoved it down his pants trying not to make a sound.  Katsuki turned around to give him the box.  Izuku angled the emptied box to hide a bit of his backside.  Luckily, Katsuki’s phone had chimed and looked away.  

 

Saved by the bell.

 

Izuku sprinted towards his room, nearly activating One For All. He made sure his door was locked, then pulled out Katsuki’s boxers from his pants.  Why he was mesmerized by the aroma, he couldn’t fathom—only that he put it closer and closer to his face until it smothered his nose.  

 

Oh my god.  I’m sniffing Kacchan’s boxers.  Oh god.  What is wrong with me?!  Oh god. OH GOD IT SMELLS SO GOOD!

 

Izuku breathed heavily in Katsuki’s scent.  Something deep within him started rumbling, pouring out into his chest.  He was crooning.  Izuku couldn’t believe he was crooning thinking of Katsuki’s crotch.  What the hell is happening to me?  Why am I thinking of Kacchan’s dick?  

 

Kacchan’s cock was in this specific underwear not too long ago, the emerald-haired boy thought.  He suddenly had the urge to touch, lick, and swallow Katsuki’s cock so bad—wanted to rub it all over his face and breathe in deep Katsuki’s scent.  He imagined Katsuki furiously rubbing his hardened dick and ejaculating cum on Izuku’s face while he looked up at Katsuki.  Izuku then imagined pushing Katsuki to the ground on his belly and forcing his legs apart with his quirk.  Katsuki would struggle, but it would be useless against One-For-All.  He would then accept his fate as Izuku fingered Katsuki’s hole, stretching him wide enough to take his dripping cock.  Izuku would then impale him mercilessly from behind as he grabbed his waist.  Katsuki would scream and beg, which only made Izuku fuck him harder and faster.  When Izuku reached his climax, he would bite Katsuki’s neck while gripping his bruising waist and come inside him.  Katsuki would sob underneath him after it was all over.  He looked so pretty in his pain.

 

No!  No, what the hell am I imagining?  I wouldn’t rape Kacchan ever!  That’s fucking sick and wrong.  Where the fuck are these violent thoughts coming from?  Why am I thinking like this about my childhood friend?

 

Izuku’s mind was in a haze.  He shakily took the boxers and searched for his ‘dirty clothes’ box.  Covered by piles of clothes was a hidden box at the bottom that kept his dark secret—a fleshlight.  Izuku had discretely bought the item online during his second year to help with stress.  Who could blame him; he was a teen with urges.  It was embarrassing enough when the unmarked package arrived at his address.  Luckily, his mother was clueless, thinking it was another one of his precious All Might merchandise he bought often, so she never bothered to check the package.

 

He breathed deeply and shoved the underwear into the fleshlight as much as he could. Izuku pulled down his waistband, grabbed a bottle of lube from the box and poured it onto his erect cock.  Ever so slowly, he started to penetrate into the fleshlight.  The whole time, he thought about Katsuki’s slim waist, taut abs, and his perky pecs.  I want to lick his pecs.  Let me just bite those nipples, just once.  The scent of caramel was overwhelming for Izuku’s senses, making him lose critical thinking. 

 

Izuku’s mind became blank, thinking only of his immediate urges, and chased his orgasm until he came…a little too quickly.  He pulled out of the fleshlight and stared wide-eyed at the sticky substance covering the boxers.  Post-nut clarity hit hard.  Oh, god! I just came using Kacchan’s boxers…I’m a fucking pervert!

 

Izuku was embarrassed and horrified at what he did.  He chucked the fleshlight as fast as he could in the small box and placed the clothes on top.  No one would ever go through Izuku’s dirty clothes, right?  Izuku went to the bathroom to wash his hands and wash his face to cool off.  What have I done?

 

Knock. Knock. Knock.

 

“Oi, loser.  My old hag bought some snacks for you.  Said I have to share or she’ll give me shit.  Anyway, dinner’s ready downstairs.”

 

Oh shit. Oh shit. Oh shit.  Just act natural!  “Okay! I’m coming! I mean, I’m heading down on you…I mean with you!  Fuck!  I’ll be there in a bit!”  Great, first thing out of my mouth are sexual innuendos.  I really am a dumbass.

 

“The hell, nerd?  You’re so fucking weird,” Katsuki said as he started to walk away.

 

Izuku opened the door.  Katsuki turned around and gave him a puzzled look.  He can’t suspect what I did.  There’s no way he knows what happened.  Don’t freak out.  Don’t freak out…just breathe.  This never happened.  I had a moment of insanity ‘cause I’d never actually touch Kacchan in a sexual way, no matter how hot he looks with a six-pack.  And those eyes…Fuck me.  “Uh…s-sorry Kacchan, I got frustrated packing.  I need a break,” Izuku said quietly.

 

Katsuki held Izuku’s gaze briefly, then looked away.  “Whatever.  Let’s go before the extras eat everything.”

 

“Okay.”

 


 

Once Katsuki got the old hag’s text, he quickly texted he was heading down and grabbed the permission form and a pen before getting into the elevator.  Katsuki hoped he’d make it before—

 

“Ahh! He looks like a cute little gremlin, Mama Bakugou!  Please, I beg of you send me this pic,” squealed Mina.

 

Denki and Hanta were looking at Mitsuki Bakugou’s phone over Mina’s shoulder.  “Cute is not something you ever hear when describing Bakugou.  Uh, no offense ma’am,” Denki said as Hanta snickered.

 

“None taken.  When you’re right, you’re right,” Mitsuki laughed.

 

Eijirou waved his hands in front of the group, “Come on guys, let’s not talk about him like that.  He’s gonna be pis—”

 

“WHAT THE HELL HAG?!  WHY THE FUCK YOU SHOWING THEM BABY PICTURES OF ME?!” Katsuki roared as explosions sparked in his palms.  He’s gonna destroy that phone, like right now.  And a few assholes.

 

“Told ya,” Eijirou sighed and walked away—definitely the smartest of the group.

 

“Calm down brat,” Mitsuki said as she snatched the phone away before Katsuki tried to explode it.  “I have a hard time getting you to talk about school or much about anything when you’re at home.  I thought I’d ask your friends how you’ve been doing. They were more than willing to tell me some interesting things.  One thing led to another, and we were talking about how you changed over the years.  But it seems like that volatile personality is as strong as ever since you were a toddler,” said a smirking Mitsuki as she put her phone in her bag for safe keeping.

 

“You didn’t have to show them my damn baby pictures!”

 

“Sorry, Bakugou.  I kinda asked your mother how you were like back then and asked to see if she had any pictures.  Please don’t be mad at her.  Blame me if you must,” Mina said nervously as she bowed, twisting her fingers.  “You looked very adorable as a toddler, though,” she said with a bright smile.

 

“Tch.  Fucking fine,” Katsuki said.  Then he walked to the common room ahead of his mother.  Most of the students left the area to head over to the tables to grab dinner.  “Old hag, I need you to sign the permission form now, then you can go.”

 

Mitsuki sat on the couch and grabbed the pen to sign the form.  “Katsuki, I know I sound like a broken record, but could you at least try to be nicer to your friends?  They seem like a decent bunch compared to your middle school groupies.  I’d hate it if you drove ‘em away with your…explosive personality.  Please don’t lose this group of friends you have.”

 

“Don’t worry about them.  I don’t make friends with cowards and losers anymore.  And if they can’t handle my ‘explosive personality’, then how the hell will they be able to deal with villains as pro heroes?”

 

Mitsuki tilted her head to the side in thought.  She smiled and ruffled his hair, “Sounds like I raised you right, then.”

 

Katsuki grimaced.  He wasn’t comfortable when his mother was being too soft.  

 

“Anyway, I did come bearing gifts, so it’s not too bad your mother stopped by,” Mitsuki said as she picked up several convenience store bags and placed them on the coffee table.

 

Katsuki started grabbing items from the bag—melon and blueberry Ramune sodas, chocolate and strawberry Pocky, matcha-flavored mochi, strawberry-flavored mochi, onigiri rice balls, Calbee Jagabee potato sticks, egg sandwiches, wagashi sweets, and several water bottles.

 

“Shit, this is a lot of junk food!”  Katsuki couldn’t wait to try some of the snacks.

 

“Hey brat, it’s not just for you.  You need to share with Izuku.  Think of it as a small gift for all the hard work you both did this year.  I would have planned something better than junk food, but this is kind of last minute.  Maybe Inko and Masaru want to plan an outing or something.  We’ll see what we can do.”

 

“Nah…this is good stuff.  Deku loves this shit,” Katsuki said as he put the snacks back in the bag.

 

“Before I head out, one quick question,” Mitsuki said as she slid her purse onto her shoulder.

 

“What?”

 

“You have any girlfriends yet?  Is it that cute Ashido girl?  She seems close to you.  Or boyfriends?  I’m not judging.  I’m very progressive.”

 

“Okay…we’re done!  You can fucking leave now!”   

 

Mitsuki laughed all the way as she exited the building.  

 

Katsuki glared at her as she left, then grabbed his stuff and headed towards the kitchen.  He stored the snacks in his personal section of the pantry and fridge to get later after dinner.

 

Katsuki grumbled all the way up the elevator.  Why the hell did she have to ask such an embarrassing question like that?  He doesn’t need a girlfriend.  He’s gonna be a damn pro hero—the number 1 pro hero.  There’s no time for romance or any of that lovey-dovey shit.  

 

The elevator dinged open to his dorm room floor.  He headed towards Izuku’s room to let him know about the snacks and tell him dinner was ready.  Katsuki knocked on the door three times.

 

“Oi, loser.  My old hag bought some snacks for you.  Said I have to share or she’ll give me shit.  Anyway, dinner’s ready downstairs,” Katsuki said as he heard muffled sounds on the other side.

 

“Okay! I’m coming! I mean, I’m heading down on you…I mean with you!  Fuck!   I’ll be there in a bit!” 

 

Okay….What the fuck was that response?  Deku’s also cussing again.  “The hell, nerd?  You’re so fucking weird.”  Katsuki was too tired to care about Izuku’s antics right now and started to walk away.  He just wanted to eat and sleep already.

 

Finally, the nerd opened his door before Katsuki could get that far.  He turned around and smelled…the forest?  Except it was really potent, like if he was in the middle of the forest during a torrential rainfall—the earth was damp and the fresh air smelled of ozone.  Whatever it was, Katsuki admitted the aroma was intoxicating.  He was just too embarrassed to bring it up.  Thankfully, he didn’t have to as Izuku began talking.

 

“Uh…s-sorry Kacchan, I got frustrated packing.  I need a break,” Izuku said quietly as he looked at Katsuki with those big emerald eyes.

 

Huh…Deku seems kind of…adorable?  I must be dead tired or having a stroke right now.  Deku?  Adorable?  As if!  “Whatever.  Let’s go before the extras eat everything.”

 

“Okay.”

 


 

Izuku and Katsuki were the last of the class to get their dinner.  Sato and Ochaco had made delicious hamburgers on toasted buns while Tokoyami and Tsuyu helped prepare side dishes of sweet potato fries, chopped carrots, and white rice.  Everyone else had finished and went to either the common room or to their rooms.

 

Katsuki ate quietly while browsing his phone on the website News of the Weird .  It was an entertainment news website but was still legitimate for breaking news about topics relating to pro heroes.  He clicked on a recent article that seemed familiar to what Mina and his mother had mentioned earlier that day.

ATTACKS OF CIVILIANS ON THE RISE

Is An Unidentified Quirk To Blame?

By Imamura, Naoko

 

March 27, 2xxx

 

MUSUTAFU, Japan—There has been an increase in attacks on civilians—not by villains, but by your everyday salaryman, neighbor, friend, or family member.  When asked about what caused these people to ‘snap’ according to witnesses, none of the aggressors could explain the reason they attacked.  A majority of the assaults have been physically violent.  There have been, however, several sexual assaults that have led to victims being hospitalized.

 

One victim, who allegedly has been affected and asked not to be named, has reported to have described the feeling of a ‘monster’ inside of him forcing him to do ‘inappropriate’ things.  As to what he meant by that statement, he became nervous and declined further questioning.  He merely insisted he never took medication or was exposed to any external factors [that he is aware of].

 

Is it paranoia?  Mass hysteria?  A villain’s quirk?  Or possibly an undocumented quirk in effect?

 

According to authorities, they are investigating along with several pro hero agencies the cause of the outbreak that has been random and sporadic, affecting an unknown amount of civilians.  Earliest reports indicate it started around late February—early March due to the uptick of strange behaviors documented by the Musutafu police and pro heroes.  So far, there is no known cause.  We will keep you updated on this ongoing story.

“Shit, this is fucked up,” Katsuki said as he read the article.

 

“What is Kacchan?”

 

“Remember what Pinky was talking about during lunchtime?  Well I found the article.  Apparently, people have been attacked at random by regular fucking extras for no reason.  One victim, or whatever the fuck you call him, said it was like having a monster telling him to do inappropriate stuff.  Many were violent attacks and a few were sexual.  Fucking sick fuckers.  Don’t care if they got affected by whatever quirk.  Their dicks need to be blasted.  That should stop ‘em,” Katsuki growled as he stood up and went to the sink to wash his dishes.

 

Izuku’s eyes were wide open.  Oh no.  “M-monster?  Telling him to do…inappropriate stuff?  Like…what kind of stuff?”

 

“The fuck I know?  Article didn’t say.  Definitely nothing good.”

 

“Oh.  Yeah…right…”

 

Katsuki turned around.  “Look nerd.  The pro heroes are on it.  Police are on it.  And we have our provisional licenses if we ever get on the case.  Just keep your eyes and ears open.  Besides, we can take care of ourselves.”  Katsuki put his dishes away and grabbed a Ramune melon soda from the fridge.  "There are some snacks the old hag got for us in my section of the pantry and fridge," he said as he headed back towards his room for the night.  "Don’t eat all the Pocky, fat ass."

 

Izuku looked at Katsuki as he walked away.  He couldn’t tell him.  He only heard that voice once.  That’s not enough proof he had been affected, right?  Not enough to be alarmed.  Maybe he was really, really horny.  He was a teenager anyway.  Raging hormones and not enough pleasure time probably was throwing him off balance.  Izuku needed to squash his urges quickly.  He had to.  He’s gonna be a pro hero soon.  Besides, whatever the hell that voice was, it was only affected by Katsuki, and Katsuki can handle it if Izuku did anything ‘inappropriate’ to him.

 

Fuck, who am I kidding?  He’s gonna blast my dick off!

 

Izuku decided to call it a day and headed upstairs to sleep after he grabbed the strawberry Pocky.  Tomorrow was the last day of their second-year term.  Best to leave it on a positive note.
