Chapter Text
Aizawa’s head felt like it would split in half. He got up from bed slowly, grunting as he turned off the alarm and massaged his temples. The small letters on the phone’s clock read Friday. The week was almost over. Soon he would rest, but first, he had to go to class. Get his students as ready as they could be for the harshness of hero-work ahead of them.
Clumsily, he wobbled to the closet, grabbing one of his clean hero uniforms and getting in the bathroom, following through his daily routine. Yet unexpectedly, he tripped on a pile of clothes from last night, quickly holding on to the sink to avoid falling to the floor. A mumbled curse and a racing heart to wake him up faster. It seemed he came back so late from night patrol, he couldn’t even bother to pick his clothes up.
How careless , he thought as he washed his face. Next time he’d put it on a hanger at least. He couldn’t even remember taking his clothes off last night, as if someone else had put them there. Eerie. Chiyo’s words telling him to please take a break from patrols now started making sense if he was tired to the point of memory loss. A shame he didn’t follow through her recommendations, neither students or hero-work could wait.
Up until that point, Aizawa’s day seemed more or less normal. Perhaps, it just wasn’t his best. His joints ached from last night, his head still bothered him, and felt like he woke up on the wrong side of the bed. But as uncomfortable as it was, at the same time it was pretty mundane.
And yet what happened next was not only out of routine but a complete inversion of it.
On an average day, Aizawa would walk up to the class, listen to the 1-A students fooling around in the classroom, some joking or commenting on their week. Then watch them as they scurried away to their seats the second they noticed their teacher getting close.
Instead, Aizawa was surprised at how quiet the classroom was as he walked down the hall, not sure what he would stumble upon once he opened the door.
Almost two dozen eyes were on him immediately, each of them showing different levels of terror. He wasn’t that scary was he? All kids were sitting at their respective desks as if he had already come into the classroom. He raised his eyebrows, as the students just kept staring at him like they were seeing a ghost.
“Good morning,” He muttered.
As if he lifted a curse, several students screamed in confusion. Some of them jumping up from their desks and running to one of the windows, which Aizawa noticed was open, while others rushed right upclose to him with a baffled look on their face.
“Mr. Aizawa?! How did you get out the window and came back so quickly!?” Mina practically shrieked.
“He changed his clothes too!!” Mineta pointed out while trying to climb on one of the desks to see the teacher better.
“My clothes have been the same since I got here.” Aizawa dead-panned but he was ignored in favor of the Bakugo’s barking.
“Dumbasses, he didn’t come back!” He yapped, always fast to understand situations. But he was cut off by one of the kids at the window.
Ojiro was pointing at something outside, making everyone try and look over his arm, as he commented along with other students who had a better view than the rest of the kids.
“Mr. Aizawa is still outside!”
“He’s running!”
“He’s still chasing the cat?”
“No, the cat jumped into a bush... he’s just looking around…”
Worried by the increasingly strange commentary, Aizawa rushed to look out too, just enough to see a sliver of someone jumping through an open window into an empty classroom across from theirs. Were they using his pink pants?
“He got into the school again!!” Another of the students shouted next to him. Confirming that, indeed, this was who was impersonating him, and most probably stole his clothes.
Not wanting to lose more time, Aizawa reached for his phone and messaged Hizashi, realizing too late he wouldn’t pick up during his lessons. The teacher quickly called for Iida to take care of the class for a few minutes and rushed to 2-B’s, knowing Mic would be there.
A few hand signs shared from across the door glass, and Mic was already out of the room, asking the students to start reading until he came back, so he could check on his distressed friend.

“No. You can’t tell Chiyo.” Aizawa grunted as they walked into an empty classroom to see what they could do.
“Huh, why not?” After receiving no answer, Mic turned to him and frowned. “You shouldn't even be here having class. Should you? You are so thickheaded, man. Has she told you to rest again?”
Aizawa muttered something in reply, sliding the classroom window open to check outside, just in case the clone appeared running down the garden.
“You should have called me in earlier and I would have covered you…” For a moment he sounded almost offended but then cracked a snarky grin. “I can't split between two classes like some people. Ha!” Aizawa only gave him a hard look, making Mic soften his smile, deciding the teasing was enough “I'll call 13 and see if they can handle it.”
The muted sound of things falling a few rooms away was followed by a sharp scream.
Yagi.
Both teachers exchanged a nod, Mic stayed to call 13 on the phone, while Shouta's feet practically moved on their own as he jumped over desks and made it out of the classroom.
More shuffling, a door closing and Yagi's muffled cough. They sounded close.
He turned right. Then left.
Then another thing falling in the distance.
The only place that could be coming from was -
He kicked the staff room door open.
There was no one there.
He grabbed at his capture weapon. Feeling strained, trying to breath slowly. It didn’t work, but he still needed to calm down. They couldn't be too far now.
Walking around the teachers desks he stumbled upon Yagi's chair on the floor, papers spread everywhere... A few steps away, there was a wet stain and a cracked cup on the floor. God, what did this idiot do now? What did he do?
A muffled whine made his head turn like a whip. The door to the kitchenette was closed.
In two steps he crossed the room, only for the door to slide open before he could reach for it, and the full weight of Yagi's back fell on top of him. Throwing them both to the floor.
“God!… I’m so sorry!…T-this isn't…” Yagi stuttered, trying to pry himself off from whoever he landed on. Aizawa couldn’t speak or move before he saw the clone, grabbing Yagi tightly by his suit's belt, making it harder for the older man to move anywhere. “A-aizawa please…” Hearing Yagi’s voice so high and stuttery- What were they doing?
“Hm, You were so happy moments ago… Are you worried about getting caught? I’m better at hiding than you think, All Might.” The clone answered with a lustful grin on his face. “ We both are. ” He looked away from Yagi, meeting Aizawa’s confused but furious stare. Protective of his coworker, he was still sitting in the same position on the floor, holding Yagi up from behind his back.
All Might turned his head slowly, afraid of who could be the person the other Aizawa was talking to, only to freeze when he noticed the same black stubble and eye bags on the man holding him.
“T-there’s two of you?” He stuttered.
“A villain hit me with his quirk last night.” Aizawa said in a monotone voice, a funny contrast to his co-worker's surprise."I'm sorry it's gone this far, All Might.”
He tried to untangle from the two on top of him, ready to beat the shit out of this doppelganger.
Just when he could free one of his arms, the other grabbed him by the wrist and pulled him back down, firmly pressing both of his palms against Yagi's chest. The small shiver of All Might’s body against him was hard to ignore.
“Don’t move! You both look so nice like this. It’s hot…” He heard his own voice rumble from below Yagi’s navel.
The clone was shamelessly pressing his face against Yagi’s inner leg, gripping his pants with one hand and pinning Aizawa to the older man’s chest with the other. As he nuzzled Yagi, a strained moan escaped the blonde. It was so different from his usual voice, it made Aizawa look down at him. Hot the clone had said… looking at the light blush on his co-worker’s cheeks, he couldn’t help but agree in silence.
Yagi tried to cover his face in shame, but found it difficult with Aizawa’s arms in the way. "I apologize about this too…" he whispered looking up at him. Then back down to the clone between his thighs. "I didn't- you are not Aizawa…?" The confusion in the teacher’s face was exasperatingly cute, Aizawa thought. Even more from this angle, having him perched on his lap.
“You didn’t seem to mind it before.” The clone deadpanned, propping himself up a little. “Don’t make me think about it too hard.” He insisted “Just kiss and make up already so we can k-”
“Shut up.” Aizawa growled. Stretching one of his legs to kicking him in the face. “Who do you think you are? Whatever you are saying. You think All Might will let you just do whatever you want, just like that?”.
He unconsciously pulled Yagi closer.
"All Might, whatever happened, I can inform Nezu about it. I didn't think it would go this far."
"No! Don't call Nezu!" Yagi stared up at him, his hair getting messier with each move. "I… Shouldn't be teaching today…"
"Sneaking around?" Aizawa couldn't help but chukle under his scarf, something about both of them having a dumb tendency to go to work, even when they shouldn’t, warmed him up.
"What a bad boy." The clone slurred, making Aizawa half-heartedly kick at him again.
To stop a brawl from breaking out, Yagi blurted out, "We can go to my room."
“Huh,” the clone purred. “I'd never thought you'd ask-”
“Shut up.” Aizawa grunted, yet was left with no choice than to trail behind them.
----
Yagi stared at Aizawa from the couch. A blush covering his cheeks as he sipped from his teacup. The clone pressed against his side, leaning into him with his eyes closed. Both listening to the teacher.
"The students said you jumped out the window to chase a cat." Aizawa frowned, serious.
"It was a real pretty one." The clone mumbled, pressing his face closer to Yagi, who put a hand against his forehead to stop him from reaching his neck.
The tension wasn’t helped by Aizawa, glaring at them from the other side of the room, knowing All Might was so patiently letting this stranger run their hands all over him. Worst even was the small sensation of jealousy on how nonchalant and happy the clone looked. Who does he think he is?
"He seems to be really... impulsive." The blond pointed out in a calm voice. Almost as if nothing was out of the ordinary. "You don't know how this quirk works?"
"No, I just woke up to this... -Aren't you a bit too comfortable?" Aizawa snapped, making All Might tense a bit. The clone lifted his head half-heartedly, disliking the sourness in Aizawa’s tone.
“Well, I… Wouldn’t like him to run away! If he’s so rash, I mean....” Yagi tried.
“I won’t,” The Aizawa next to him said against his ear, making Yagi hold his cup just a bit tighter. “...Unless you want me to.” Something in his voice made Yagi’s heart skip a beat. He gave it his all to say nothing and drink a mouthful of tea. Following Aizawa’s logic, this couldn’t be the real teacher. Could it..?
The real Aizawa took a hold of his capture weapon a few feet away, a dangerous aura surrounding him as he spat the words through his teeth. “You are talking like you have an option here, you hindrance .”
“Aizawa stop!” Yagi raised his free hand, attempting to keep the teacher from lunging forward “If we don’t know how the quirk works, we need to be careful. What if you hurt yourself in the process?!” Luckly, it proved enough for the other to take a deep breath and let his scarf fall over his neck.
“Let’s think about it a bit more...” Yagi kept saying “You had to fight the villain’s clones, right? Do you remember if they acted separately, or if they followed orders?”
“I don’t think so…” Aizawa answered, not taking his eyes away from the clone. “I wish I could have seen them interact before having to fight with them. The villain didn’t use the quirk on himself but on his partner, a girl with a speed quirk who knew a bit about martial arts.”
“It makes sense... They were rookies then? But... if they could fight you all at once, then there must be a way for them to coordinate themselves.” Yagi took a sip of his tea. Remembering about other similar quirks he’d seen in the past. “Could you get to see if they faded away after a while? Were the clones captured or did they disappear before the police could catch them?”
Aizawa hummed and crossed his arms, thinking. But his mind was blank. He was reminded of the clothes he found on the bathroom floor that morning, the same feeling of estrangement filling his brain.
“I can’t remember.”
“What?...Not even filling the police reports...?”
“The police reports…" Aizawa scratched his head "Hm...We could ask the po-”
Before they could keep talking, the clone made his presence known again, lazily stretching past Yagi’s chest and cupping his hand and cup. Breaking their train of thought. With a defiant glint, he sat back and stared at Aizawa as he pulled the larger man’s hand to him and sipped from his cup. Yagi’s face went red as he let Aizawa move him as he pleased.
“You little-” In a second, what little patience the teacher in front of them had collected was dropped as he lunged forward towards the clone.
“The copies disappeared.” He said cheekly, just when Aizawa reached the couch ready to get him in a headlock. Again forced to freeze -much to Yagi’s brief relief- and let the clone keep talking. “The girl got a medical check up because the copies’ damage added up when she came back to herself. Getting knocked out three times can be rough on your body.”
“You are the one who remembers that?” All Might stared at him, his hand still captured between the mug and the clone’s hand. “But then…”
Before Yagi could finish, Aizawa was grabbing the clone by the head. Forcing to woefully tear him away from the old man for the first time that evening.
“Then, I just have to knock you unconscious and I'll sleep for a few days after. Two jobs in one.”
Trying to break free, the clone grabbed onto Aizawa’s arms, shoving him with enough strength to try and get him off the couch.
This was getting ridiculous, having two grown up men fighting like they were first-years in training class. Yagi sat up, putting what was left of his tea on the side table.
“Aizawa! That’s enough!” He roared.
Both Aizawas turned to stare at him, and it was frightening how synchronized their movement was.
“Damnit you two! You bother me about my health nonstop, and don’t give a shit about yours? Can you just focus on this for a second!” Yagi cleared his throat by the end, noticing he was hurting his voice. As he grabed for his handkerchief, it felt like the wrong thing to say, as neither of the teachers stopped staring in his direction.
“Focus on you?” The clone in a chokehold grinned, while the one holding him down just blushed. Aizawa wanted to tighten his grip when he heard an echo of his exact thoughts, but released the other regardless. Not wanting to make this even more of a problem for Yagi that it already was.
