An- My artwork of gendbent Koyuki.
===
How in the world did it end this way? How did classes A and B involved others to their mess? First, we must show how the battles progressed before the reveal of the mishap.
"Koyuki! Come here!"
Midoriya's voice suddenly rang throughout the steaming baths. Since both genders were seperated by sex, it's only fitting each side enjoyed their luxury given by the school. The boys snapped towards their green haired classmate. Who, mind you, is befuddled at the sound of his own voice ringing out.
"The fuck you doing, Deku?!" Katsuki grinding his jaw in rage, not quite understanding the greenette's mind in calling the Dragneel here, in the boys baths. Sitting far away from the others, although Eijirou, the brave soul, didn't fear any death threat by the explosive ash blonde. Although close friends with Izuku, Kirishima was flabbergasted that Midoriya would boldly call the Dragon Slayer to enter the BOYS bathroom.
Panicked with all the mortified looks from the other males in the baths, waving his hand before his flushing face. "I didn't say that!" Worse when Tenya and Fumikage looked to him with their jaws unhinged, speechless. Iida Tenya and Tokoyami Fumikage had no words what to say towards the greenette on this.
"That was your voice!" Hanta joined in argument; he clearly heard Midoriya's voice calling out the girl. Trying to shove Mineta's excited face away. The deviant individual kept throwing thumbs up towards Midoriya, obviously in agreeance with them.
"I--" Before Izuku could explain, another voice interfered. "What's up, Izuku?"
'She came!' Many internally screamed, unable to believe the girl nonchalantly entered without their notice and even heard Izuku's call. Not only that, once many snapped towards the girl's direction and to their horror [or happiness for a select few], the silverette came in without wrapping a towel around her voluptuous figure. Without her long lushes hair to censor her round breasts and leaving that job to natural steam around her form. Censoring her privates, yet bare before the eyes of her male peers.
"...ah..." Were Izuku's mortified peep, till slowly his skin glowed red. Unable to believe that the girl boldly entered nude before their very eyes. Yes, he's seen Koyuki naked, because of her habits! It was not his choice! But how could she enter without a care in the world and not be flustered to see her male friend completely naked, whiles she's bare too. Shrilling out the top of his lungs in such a high pitch that his voice cracked, "Koyuki!!!"
Both Denki and Minoru grinned broadly, faces bloody red with perverse glows in their eyes. Bringing their hands up to clap in thankful prayer, "Thank you for the..." Slowly losing their composure at Katsuki's body slowly turning and revealing his red visors that glared heatedly, while aiming his crackling hands towards them. Not only did Katsuki's malicious glare made their blood grow cold, also seeing Shoto's glare from behind and his slow motion of conjuring glaciers of ice towards their direction yet their emotion seemed to aim all, "view--"
Kyoka squealed and pressed her body to the wall from the ice piercing from the doorway. Momo and Tsuyu looked to the protruding ice coming out of the doorway to the boys bathroom. Both completely in awe at the ice, not knowing that the boys inside were frozen stuck due to Shoto's Quirk. Leaving those inside to shiver in place and for Koyuki to crouch and munch on ice, which she ripped from the ground, happily. Izuku kept his eyes clenched tightly closed, even he's frozen in the once warm waters, Koyuki's naked body was beside him. Attempting to dig him out by eating the ice.
"Koyuki! Come he-he-he-here!" Many heads snapped towards Izuku's direction, but saw Koyuki looked to another with just an appalled reaction. Looking to where she was looking and saw it. Clear, shivering, rage at the sight of a radio- that's pushed out its hiding due to the ice- in the corner.
"SON OF'A BITCH!!" Blowing up the ice around him, Katsuki marched out of the whole he created. Not unnerved with a girl in the room now, not when they discovered where "Izuku's" voice coming from.
Although his head was the only thing popping from the ice, Tenya's face flared red from seeing the object and knew who were the culprits that caused all of this. "THE NERVE!!" Even Mezo, even though he still wore his mask, strangely enough, glared angrily at the radio.
Class A's comeback?
Monoma looked to his classmates with such a pale complexion as he was being escorted out of their dorm in cuffs and two officers behind him. The boy thought it was all a joke, two police officers knocking on their door and asking for Monoma Neito presence. That's until one of the police officers revealed a warrant and Kendo- who stood behind the boy- frozen in her spot. Turning to the Copycat Quirk user with questioning eyes. It horrified Neito to see everyone staring him with questioning eyes. Unable to believe that his peers to believe he actually broke a law that needed his arrests. The hilarious reveal was when the officers said, "Monoma Neito, you have the right to contact a lawyer or smile for the camera." Perfectly looking to the waiting polaroid that snapped its flash and the image printed out with round baby blue eyes of shock.
Of course students in class A wondered how the hell the police even agreed to join. Thankfully, Toru asked the mastermind who requested their assistance, "How the hell did you get cops to join and also get them into the school, Koyuki-chan?"
Her wonderful response, "They owed me for beating them on poker and they told Nezu they were checking in on me. He nor Aizawa didn't suspect a thing." The perks of being a Fairy Tail wizard.
---
Of course class B had a comeback ready for class A.
"Oh, excuse me." The girl meekly apologized towards the Dragneel, her thick, round glasses on her button nose. Eyes clenched shut bashfully with her face deeply red. Her bony hair tied up in a messy ponytail. Bowing towards the silver-pink haired mage looking down the girl with a kind smile. Waving off their apology, "No problem." Koyuki frowned in confusion, her voice sounded oddly deep. But shrugged it off as if it were nothing.
The girl quickly snapped up and ran away from the mage, muttering erratically. Strange, she heard the shy teen squealed "They're so handsome!"
With that, Koyuki pivoted towards the direction where the girls left to change into their hero outfits, since the stranger suddenly bumped into her. Entering the changing room and went to her locker that's next to Ochako.
Uraraka hummed a tune under her breath, a song Koyuki sang during the sports festival. Ochako froze when she saw someone stripping beside her. Glancing to her side to see a male unbuttoning his dress shirt that is the girl's school uniform, tuat due to his broad shoulder's and obvious show of muscles beneath. Their salmon-white hair low and wild, his bangs a bit spiked and framing his handsome face, even if they had a scar on their left jawline.
As if feeling the brunette's stare, they shifted to meet her gaze. Their dark, soft, eyes watching Uraraka expectedly with a quirked brow. All Ochako did was glance down and see their abbs under...he has an eight pack?!
"KYAAAAA!!!" The girls around- who were in mid change- snapped to Uraraka worriedly until they, too, spotted the stunned male. Screeching in embarrassed horror at the fact a boy was stripping in the girls locker rooms.
Confused and panicked at the girls screaming and lethal attacks, they rushed out the room to boys locker and cried out for the greenette's aid. "Izuku! Something happened!!"
"Wah--" Midoriya snapped to the shirtless stranger who looked to him with frantic borts. Unnerved, and yet they seemed strangely familiar and was unsure as to why. "Um... Who are you?" Many of the other paused in their changing and were just as confused and appalled at the strangers entrance.
Taken aback at the question, their hand pressed to their bare chest. Clearly hurt. "It's me, Koyuki!"
Surprisingly, Izuku was not amused with the young man's declaration. His freckled features stoic in disappointment and thinking this was a terribly poor joke, "Yeah, very funny--" The young man slapped his left shoulder angrily with their face scrunched in exaggeration, revealing the Fairy Tail symbol with gray-silver outline and the inner is sky blue. Not only that, their hand's manifesting mist and frost that formed a scale-like armor up their arm.
How foolishly wrong he was.
"Koyuki?!" Blinking owlishly, stunned that the girl is now a boy! Instantly realizing they were in the boys locker, half naked and also seeing them all half nude as well. "KOYUKIII!!!!!" Throwing his shirt over Koyuki's face, on his tip toes to hold the shirt over the Dragneel's face and censor her, now, male body. To say, it's difficult to cover their face when they're six feet tall!
"GET THE FUCK OUT YOU IDIOT!!!" Bakugou cried out in the back, even though there was utter confusion behind it.
"DRAGNEELN-SAN!!!" Was Iida's voice crack, utterly mortified that it's the Dragon Slayer again inside the boys locker room.
"I'm sexually confused!!" Mineta cried in horror, unsure what to think anymore.
"I'M GONNA MURDER YOU, YOU LITTLE SHIT!!"
The boys predicament was quite comical. Katsuki being held back by Eijirou, Sato, and Mezo, while Denki and Hanta tried to ease the deadly aura Shoto begun to radiate. Tenya, like before, hid behind the curtains from Koyuki's sight. This also included Fumikage and Koji- who trembled in fluster upon knowing it's Koyuki- not wanting to be seen half naked.
With the girls: Kyoka- having her earphone jacks pierce the wall- heard all the commotion coming from the boys side and discovered who that mysterious intruder was. She stood by the wall, stunned. Leaving the girls to chatter frantically to themselves.
"Did you see them?! Eight packs!! Eight!" Mina couldn't get the image of the handsome stranger. She thought they were the description of a sculpted beauty of a Greek God. Their chest perfectly chiseled, arms pulsing with muscles that seemed like they could cradle you protectively.
Toru pivoted to Ashido's direction, a prominent red blush coated in the air; obviously her cheeks. "Is that all you saw. I thought my heart was going to explode!"
"Not as much as Ochako." Tsuyu pointed out, watching the girl in question worriedly. Seeing that the brunette was fanning her burning face. Completely red and pacing around the room with a high pitch squeals of confusion.
"He's a she. He's a she. HE'S A SHE!" Momo turned to the Earphone Jack user, seeing them muttering loudly as if to convince themselves of something. "Why are you chanting?"
The rest now focused their attention on the raven haired on the other side. Jiro shakenly turned to them with a deeply flushed complexion, "Tha-That was Ko-Koyuki-chan..." Gaining the reaction she thought she would get: they all squealed out the mage's name, clearly stunned. Hearing Tenya's voice on the other side, believing Koyuki left them to recollect their frantic minds from the sounds of it. "Midoriya-kun, wet your face. You're completely red."
As the greenette fanned his face, pacing around with high pitched mumbles, "Why would she do that? She knows not to do this again. This is the third time!"
Minutes later, Koyuki stood with gym clothes that fitted her male body with a complete a deadpan on her male facial features. Everyone remained silent with Aizawa looking to the now turned Dragon slayer, "I'm not going to ask what happened."
Her reaction never changing, "May I go see Recovery Girl."
Clicking his tongue in disappointment, but the already exhausted man vocally allowed them. "Midoriya. Iida. Go with her. I'll excuse Dragneel and Midoriya for today's class, but I want you- Iida- to report what caused this."
"Understood, Sensee!" Tenya oddly saluted, unable to recover from the dilemma that previously happened.
Izuku, who was flustered and couldn't seem to look up from the ground, nodded with a low stutter, "Ye-Yes...Sense..." Thus the three left the rest in silence. The trio were completely tensed, but thankfully it was broken by the Dragneel. Well, breaking the silence by swallowing her pride over phones and actually dialed a certain Solid Script mage on Earth. "Rebecca...by chance I could pay you to do something for me? It's..." Whispering in the receiver, the class president and greenette glanced to the other, wondering what she was whispering. However, with that unnerving look, even if it held a slight cringe from the static coming off her phone, they feared what the male was asking. Suddenly smirking to herself, it seemed the glasses mage agreed to the deal. "Yeah, I can do that...kay. Bye." Hours later, Rebecca actually came running and kicking their dorm's door open with a conniving grin and evil glint coming off her lenses. Duffle back looped around their shoulder. Dramatically pointing towards the waiting Slayer, "I got the goods! Now strip!"
Mina hummed to herself, "Huh...Free striping." To which Asui proceeded to throw a pillow at the giggling pinkette.
Kaminari, who stood behind the kitchen counter glanced in time to see Shoto's frozen reaction and barely laughed out in wheezes, "I can imagine the phone off hook sound effect with Todoroki's face!"
---
The next day, everyone in class A and B sat in their respective lunch tables, which are neighbors with one and another. The day was all calm, no chaos could be seen.
Koyuki, still a male since the affects would last two days, ate her rice steamed rice that's sprinkled with wheat grains. Seemingly serene and in peace with everything, even if her body still retained a young male figure. Even with the peace around, Izuku and Kirishima watched the girl, knowing something was bound to happen. That's when it begun...
Koyuki placed her chopsticks on the bowl and clapped her hands together in thanks, "Let it begin." Katsuki paused from his table at the Dragneel's voice and glanced up. Then they all heard the cries next to them.
"My body!!" Itsuka pointed directly at Neito, hear face scrunched in panic and confusion. The blonde before her was frozen, the chopsticks in their hand dropped from their frozen state. The trickster teen shakenly muttering, "How is my body over there...?"
Then another voice- Jurota this time- crying out and pointing at Pony and speaking in English. Thanks to their English class and practicing on the language, they were able to pick up the teen's perfect speech of the dialect. "Why's my body over there--? How am I over here?!"
"What is going on?!" Manga cried out, their panel seeming sharp and expressing of their exclamation. Next to them was Tetsutetsu, who cupped their cheeks, their face becoming deathly pale.
The pink-silverette male grinned broadly at the gawking audience around hearing the commotion class 1-B was causing. "Surprise mutha fucker!!"
Katsuki honestly lost it, slamming his fist on the table and almost fell off from the sight of the class B pointing at the other, seeing their bodies have switched. He wasn't alone, Hanta hugged his stomach from all the laughter, next to him was Fumikage. The silent teen attempted to conceal his reddening face, but his shoulders couldn't hide his silent laughter nor Dark Shadow bursting out and laughing hysterically. Koji kept trying to conceal his snorts, but would drop his head on the table and wrap his arms around his head, snorting some more. The rest either attempted to contain their giggles or were laughing their heads off.
Kaminari stood up and proudly pointed at the other class, "Gotcha bitch!!" Proudly puffing his chest and laughing for class B to hear.
Not realizing the other departments glared towards the two classes, their bodies also switched. "This is war against the Hero department!" The class president from class C declared, to which the other classes from the General, Support, and Managing departments nodded in agreement.
Daisy, who's also a victim and now in Hitoshi's body, nervously sighed out, "Oh, dear." Seeing her classmates quite terrifying glows in their eyes. Shinso, in Namine's body, who sat stiff in his seat. Namine kept trying to form wings, but ended up reverting to the small orange feline. Daisy watched Koyuki's and Izuku's class worriedly with Shinso's tired eyes, 'Koyuki, what have you and the others started?'
---
For once, the Support department thanked Hatsume's babies exploding. The Managing department had to calculate the trajectory and seconds the item to combust. While the support implanted the contraption under one certain seat in particular. Once lunch begun they all waited, yet kept their calm composures and watched. Daisy sweated in her seat, watching her mousy friend stare the two Hero department classes, not afraid to be spotted. Shinso attempted, but failed to stop his lips from twitching into a grin. Suddenly, they heard an explosion and someone squealing in fright then a squeak followed.
Izuku and Shoto gawked at the scene before them. Complete dread lines on their faces at the sight of Minoru, literally planted in between the mage's breasts. All they knew was there was a tiny explosion and then the small figure flew over into the girl's bust. Mineta blinked rapidly from the shock then sighed, feeling such serenity. Finally, the round haired teen felt what nirvana felt. Grinning ear to ear, neglecting the terror on other heroines faces, both class A and B. Knowing how the boy could be when it concern a woman's body. Upon seeing this, both Izuku and Shoto snapped their chopsticks in half; eyes shadowed by their hairs.
There was one thing Mineta knew, if he was going to die, might as well go out with a bang!
Although Koyuki's face remained impassive, her eyes were bulging wide. A hand cupped around her left breast. From seeing the action, a certain green haired hero snapped. Izuku didn't mean to, but his emotions got the best of him. Smashing his fists down onto the table and sending it to the ground in half due to him activating his Quirk on accident. Glaring harshly towards the perverted bastard with green electric energy pulsing around his whole body, "MINETA!!"
Who knew that Mineta could make Midoriya snap.
The whole departments, from First to Third years watched Mineta scream his head off as Katsuki dragged the boy by the hair with Shoto, Sen, and Shihai following behind with dangerous auras. Koyuki sat in her seat, still frozen, but held an aura intent to kill. If it wasn't the boys, it would be the Slayer herself. Nonetheless, both classes had a short cease fire and tried to comfort the poor girl. However, stopped to hear the mixed laughter or those who cringed deeply at the sight of Mineta harassing the poor mage. Thus causing the two classes to throw their glares at the other departments and internally declare them as enemies.
Mirio couldn't help to chortle under his breath; oh, how the two First year Hero classes caused such war. His sleeve suddenly being tugged from the pale bluenette next to him, "Hey, Hey, Mirio!" Grinning mischievously now, "Let's join!"
Tamaki, who gawked the whole situation in horror, snapped towards the heroine in panic, "Nejire--"
"Good idea!" Sputtering at the blonde's agreeance.
---
There was one thing the First years should never do. Never underestimate your senior from making you look like a fool with a simple method: music.
Sitting in the common room were the rest of class A, using it as a time to do a study group and help one another in certain subjects the other needed aid on or to assist the others. It was all calm, Momo making her herbal tea for the rest and Rikido making sweets to compliment Yaoyorozu's warm beverages. With the others working on their homework or mauling over the question for a minute or more. It was all peaceful...until a sudden background music begun to play loudly.
"Close your eyes, make a wish and blow out the candlelight. For tonight is just your night. We're gonna celebrate, all through the night."
Koyuki looked around, unsure where the music was coming from. "Is that Boyz 2 Men?"
Izuku, who was drinking his bottle of water, chocked on his drink at the name of the band. Coughing for air and slapping his chest for relief. If it weren't for Tenya, who sat behind the greenette on the couch, patted the poor Midoriya to relieve them.
Irked at the "little show" Izuku just made, "The fuck are ya--" That's when the part sang out and caused a certain five to go bonkers.
"I'll make love to you, like you want me too."
Katsuki, who was about to drink his bottle of water, took a spit take and splattered all over Kirishima and Fumikage.
Ochako sputtered out gibberish words and accidentally tripped herself to float from returning from her room to retrieve her textbook. Tsuyu and Kyoka latched onto the girl from floating herself around.
Momo froze in her spot, face flushing deeply and Russian dolls being thrown around that one actually hit a window and shattered the glass.
Shoto, deeply flushed setted one of the nearest notebook on fire. Panicking, he tried to pat the fire out, but only made it larger from his own Quirk. Causing the rest to panic at the growing fires and the sudden fire sprinklers activating on. Wetting the whole room in water. However, the music kept playing for all to hear.
Unable to focus, not when such song played, Katsuki snapped around. "Where is that fuckin radio!" Rushing out the door to give their neighbors a piece of his raging mind. What's worse, the song was also outside! The whole school was playing the song! "Are you shitting me!!"
Mirio, inside the school's main building, hugging his stomach in laughter; but froze when he saw All Might stand ahead of him. The retired hero wasn't alone, behind him were Aizawa and Yamada. The tired hero scowling at Present Mic for humming along with the song then stopped from the glare.
---
The battle between other departments didn't stop. Oh, no. It progressed to the point it became a water gun war. All armed with their respective weapon from water gun, pistols, and water balloons. Of course there was some aggressive sportsmen who wanted to use ice to aim at the others, mainly Bakugou arguing with Todoroki and Dragneel to use their abilities towards the other classes. But preferred to use the weapons given or for others, their water based abilities. Scoffing, Katsuki used one trump card: boldly stating that the Water Dragon Slayer couldn't make a tsunami big enough to beat the other side. And it worked perfectly in his favor. Even with everyone begging the mage not to do it, Koyuki leapt up above everyone's head. The perfect timing when two homeroom teachers of the Hero department enter the fray.
Many students seeing this, cried out to the mage to stop in her attack. Far too late, Aizawa glared up to the falling mage with glowing red orbs, while Vlad pivoted around with bulging eyes of panic at the sight of the Slayer conjuring waves of water. To say, everyone was indeed caught in the wild waves conjured by its laughing ruler. "I am the water warrior! Warrior of the waters! The lands shall fear me!"
Mina and Denki either clapped their nose from snorting or turned away to hide their puffed cheeks that held back laughter. Koyuki butchering the Sand Guardian meme.
"Dragneel!!"
The prank wars were merciless indeed...
Extra
"AH HA HA HA!!" Hizashi began to laugh hysterically, even more at the fact it's Shota's body the one laughing. He and the other staff were also victims of the mix up, to which Lunch Rush profusely apologized for not double checking the ingredients.
Seeing this that it's his body laughing obnoxiously, Aizawa cringed at this. Glaring under the lenses, "Present Mic, quit it."
"I-- Ah HA HA HA- can't!!" Now coughing between coughs, the fact that he's seeing his old classmate's body contorting with a wide smile. It was damn hilarious and he couldn't damn BREATH! He should steal a picture and send it to Miss Joke!
"Oh that's just disturbing..." Were Midnight's- well All Might's- words. Hugging himself and shrinking into a crouch; feeling vulnerable in this clothing. Creeped out in seeing Aizawa's body laugh like a mad man. Midnight, in Cementos' body, gawked at the others, "Well now..."
Cementos, who's in All Might's, had his eyes closed and kept inhaling and exhaling; attempting to calm his nerves. It didn't work the moment his eyes snapped open and released a defeated cry, "WHYYYYYYYYYYYYY?!"
