A hop, skip, and a jump away

Summary:

It was meant to be yet another theory-heavy class day in UA, boredom hopefully chased away by a joint debate class between classes 1-A and 1-B.

Aizawa's class gets rudely interrupted by... an alternate version of himself? That's apparently in a relationship with Midoriya, of all people?

This makes no sense.

He wants a nap (and brain bleach).

Note: The AiDeku in this work does not involve underage, there is a dimension in which they are a lot closer in age and were never teacher/student.

Notes:

Hi everyone!

Well, to make things less confusing, from the second section onwards, Shouta means present!Aizawa and Aizawa means alternate!Aizawa, while Izuku means alternate!Deku and Midoriya means present!Deku.

I tagged it, but I’ll reinforce it here - there is no underage in this fic, the relationship tag is solely for the alternate universe in which their age gap is a lot smaller and Aizawa was never Deku’s teacher.

Getting all of that out of the way, I hope you enjoy!

(See the end of the work for more notes.)

Work Text:

They settle in for yet another theory-focused lesson. During the last few weeks there had been unprecedented storms, with record breaking rainfall. The only reason classes hadn’t been dismissed outright was the fact that the students lived on campus and could safely get to the building - there were city-wide reports of flooding and damaged infrastructure, resulting in rescue heroes working overtime. 

In any case, not even UA, with its money and prestige, had come away unscathed -  their bigger gyms had water damage, and their mock cities and open air training grounds were sodden and in no shape to be used. The hero course students were making do with the compact gym in the dorms buildings, using it to maintain their training regimens as undisturbed as possible. It had all the basic gym equipment and an area for sparring, but it was nowhere big enough to accommodate everyone. That had led to some animosity (high energy kids with no outlet will lead to that) before Iida quickly sketched out a schedule for them to follow and be able to use the gym unimpeded. 

It helped, but everyone was getting a bit stir-crazy. They missed the sunshine, and laying on grass, and overall being able to set foot outside without being immediately drenched. It was gloomy and cold and they almost wept for joy when the weather forecast tentatively announced a break in storms for the next week. Class 1-A was already making plans - they were going to load up on food and stay outside from daybreak to moonrise, and nobody would stop them!

Meanwhile, however, they were condensing all of their theoretical courseload to make the best of their time cooped up in a classroom. That meant lots of seminars, documentaries, and essays. Even studious Iida had lost enthusiasm, regarding their boring assignments with dread. The teachers seemed tired of sticking to books and written exercises, itching for something more interesting, as was their usual fare in UA. 

In a desperate attempt to make things more dynamic, they were setting up a debate for the day, combining classes and teachers to try and keep away the monotony. No one could sit through another documentary, that’s for sure. 

They were gathered in one of UA’s larger classrooms (and yes, Aizawa had tried getting permission to empty it and use it as a makeshift training gym, but had been denied based on petty concerns such as “noise level” and “structural integrity”), and the students had been split into groups with different themes and stances they were meant to prepare arguments for. 

Even with the lights on, the room didn’t seem to be bright enough, and while the students dutifully read through the document folders they were given, quite a few were fighting off sleep. A few had their phones or laptops out, researching bits and pieces from their topic, but most were just scanning the pages. This was meant to take all day, so they had a generous timeframe to get it done. 

 


 

Other than the occasional low mutter of groupmates discussing a point or the sound of pages turning over and pencils scratching paper, it was silent. Which made it all more jarring when the door slammed open and two figures tumbled into the room. Shouta drew a breath to berate whoever it was for being disruptive, but his voice refused to work when he realized that one of the figures seemed to be him, and the other looked remarkably like his Problem Child. 

He watches speechless as the green haired man (because it was a man, there was no way that person was under 25) quickly turns on his feet, closing the door and pushing Aizawa against it, kissing him deeply while reaching down to hike up the Erasure hero’s legs.

Shouta flushes as he sees his other self sigh into the kiss, returning it eagerly, and thinks he might just perish from second-hand embarrassment from seeing his likeness being held up against a wall and ravished like that. 

Izuku,” his counterpart whispers, confirming the identity of the other interloper. Shouta feels sick to his stomach - was there a reality in which he’s that much of a pervert? Unbidden, his gaze finds Midoriya, all of fifteen years old and with baby fat still clinging to his cheeks, which are cherry red from mortification. 

“Shouta” Izuku purrs “It’s been forever , I thought marrying you meant we’d actually get to share a bed” he sounds playful and confident, and clearly unaware of his audience “Do you know what I’m going to do to you?” he whispers teasingly, kissing Shouta’s neck.

“What” Aizawa breathes out, distracted. If they started going at it in a room full of kids he’d have to murder them both and then himself, Shouta thinks hysterically.

“So glad you asked,” Izuku says, tone low and sensual. Then he sheds his amorous disposition entirely, voice becoming cross “I’m going to feed you and make sure you sleep for at least three uninterrupted hours!”

“What” Aizawa repeats, this time with no breathlessness and a healthy dose of confusion.

“We share a bed, Shouta, meaning that I know for a fact you haven’t been in it for the last week ” Izuku hisses out, upset “I know you’ve been working on the Shie Hassaikai case, and I understand how important it is, but you’re going to get yourself into the hospital before the raid is even planned out!” he huffs “So I asked Lunch Rush to make a very calorie-dense lunch for you, and you’re going to eat all of it and then sleep for the rest of the afternoon, ok?” he pleads, gently putting Aizawa’s legs back on the floor “I know you have some grading to get done, and I can do it. My assignments are all graded already, let me help!”

Shouta is so relieved this had naturally swerved from the perilous territory it had been headed into, but still feels speechless. He wants to gather more information before interrupting. Everyone else seems similarly shocked into silence, which he counts as a blessing even though he knows he will never live this down. 

“You don’t have to take on my workload, Izuku,” Aizawa starts, but quickly gives up when he sees his husband’s stubbornness clear on his face, “ but I appreciate it all the same. Thank you” he kisses him softly, before arching an eyebrow and asking “And how exactly do you know about that case?”

“Officially, I know nothing at all, and no one can prove otherwise” Izuku says it like it was a regular disclaimer he offered “And quit deflecting! I’ve seen Hitoshi more often than you this week. Hell, Kacchan slept in our apartment more than you did these last few days” he grumbles. 

At the mention of their names, Shouta notices both Bakugou and Shinsou perking up. He absently wonderers how it unfolded, was his whole class different ages in that reality?

“How is Hitoshi’s process doing?” Aizawa asks, carding his fingers through his husband’s curls.

“I called in a few favors, they’ll be removing him from his current home within the week” Izuku relaxes against Aizawa, accepting the affection “I don’t want him going to another group home, though. Are you ready to stop pretending our guest room doesn't have purple accents and put in our bid to foster him?”

Shouta observes how Shinsou reacts, but if the mix of embarrassment and naked hope in his eyes were any indicator, he’d need to do some investigating as soon as possible. 

“That depends” Aizawa murmurs “Are you ready to admit that our pantry has food so spicy neither of us can eat it and that our laundry room has that specific detergent that I know you use to get nitroglycerin safely off of clothing?”

“Kacchan is different and you know it, Shouta” Izuku mumbles “Hitoshi is in the system, making a case for him is easy. Kacchan has his parents still” he sounds despondent.

“Izuku” Aizawa says, gently touching his chin to make him look into his eyes “Katsuki’s parents are really fucking awful. If they weren’t he wouldn’t be at our house almost as often as Hitoshi is. In fact, I wouldn’t be surprised if they made a schedule for them to alternate their sleepovers”

Once more, Shouta observes his student, and by the way Bakugou flinches he knows there is more to uncover, still. He feels a headache building already. 

“I think they made a schedule, too,” Izuku laughs. “Are we really going to try and get Kacchan?” he asks.

“Tell me you haven’t already started drafting the paperwork, that you haven’t shopped for lawyers, that you haven’t already mentally committed part of our savings to the legal fees, and I'll drop it” Aizawa says, and Izuku blushes, caught. 

“I thought I’d have to convince you first,” he sighs, kissing Aizawa in overflowing gratitude. 

“I’ll start looking for a bigger place” Aizawa says “They’ll need their privacy, and honestly I’m pretty sure they’d murder each other if they had to share a room long term”

“Make it a five bedroom house” Izuku hums, hugging him closer. 

“Five?” Aizawa questions warily.

“At least five, love. One for us, one for each of them, one for an office and…” he trails off, hesitant. 

“What’s the fifth one for, Izuku?” Aizawa presses, gently. 

“Let’s just say I know more about the Shie Hassaikai case than you think, and if my intel is right we’ll need an extra room soon” Izuku deflects with an apologetic smile.

Having finally worked up the nerve, Shouta clears his throat loudly.

The couple whirls around, finally registering the room full of people that had been incredulously watching everything unfold. 

“While this is fascinating ” Shouta starts, using every last shred of his pride to not blush “we are in need of some context.” he crosses his arms and waits.

Aizawa is the first one to recover, while Izuku is turning an alarming shade of red, likely replaying the last few minutes in his head and being hit by crippling mortification. He says “I have no idea. I’ve been locked inside classrooms and meeting rooms all week. Izuku, love, did anything happen on your end?” he runs a hand down his husband’s back, hoping to soothe some of his distress. 

“Uh, maybe, let me think…” Izuku mumbles and considers this for a moment before saying “this morning I had a new client - she was adorable, and her parents didn’t really know her abilities”.

“And what is it that you do?” Shouta asks. Pro heroes did not have clients.

Izuku scratches the back of his neck, smiling bashfully “Well, it’s a little bit of everything, really. I do some analysis to identify and strategize against villains, when the case calls for it, I do some consulting work for heroes to help them improve their quirks, sometimes working with Support companies to get them better-suited gear, and I’m also a quirk councilor!” he counts off on his fingers, continuing.

“I have clients who are kids that are just developing their quirks, while some of them have an issue with using their quirk - some people can hurt themselves before fully understanding how to use it safely! - and I also help with a Villain Reformation Program, doing part therapy and part quirk counseling with them ” he sighs sympathetically “a lot of people turn to villainy because their quirk makes it hard for them to have a regular job, and, well, everyone needs money” he smiles brightly “I just love helping people!”

“And he teaches at UA, too,” Aizawa adds, smirking proudly.

“Yeah, that too! I usually teach second and third years, to refine their critical thinking and analysis skills!” Izuku agrees readily.

Shouta hums noncommittally, not letting it show how impressed he was (from Aizawa’s smirk, however, it seems he failed). “So” he intones “your client?”

Izuku brightens immediately “Like I said, she was so cute, but no one knew what her quirk did. Her dad can store non-living items into pocket dimensions, and her mom has a quirk similar to Sir Nighteye, letting her see pieces of people’s future” he holds his chin thoughtfully “I wonder if they’re related? She did have the same shade of hair as Sir, but his public records don’t list anyone as living family. Perhaps long lost cousins? Or is seeing the future simple enough to have convergent evolution happen from differing quirk ancestors?” Before he could spiral further, Aizawa gently squeezes his free hand, in a wordless bid for him to focus.

“Sorry” he blushes “In any case, this morning’s session didn’t have a clear result. She kept making things disappear, but they’d eventually reappear with no harm done to them. Her parents thought it might be her dad’s quirk, until she accidentally did it to her baby cousin - her dad’s quirk doesn’t work on anything living. Her cousin was fine! Not a scratch on her, but seeing as she is still a baby she couldn’t exactly tell us where she went.”

“How is that relevant to today, though?” Present Mic pipes up, trying to follow the conversation.

“Right!” Izuku smiles “Sorry, I was getting to that. I theorized that maybe she combined her parent’s quirks in a mutation and can now send things or people temporarily to another dimension!” he exclaims “I didn’t have a way to test it though” his smile dimmed “I was going to ask her to test it on me” at this Aizawa looked horrified and drew a breath to doubtlessly protest, but Izuku silences him by saying “but I didn’t . I’m not dumb Shouta, I’d never suggest this without a lot of research and in the presence of people who could help control the situation if needed, which would include you, Eraserhead ”. Aizawa exhales slowly, mollified. 

“I didn’t let her test it on me, but maybe the activation requirements for her quirk aren’t clear yet. I’ll have to look into that, and suggest they keep a quirk-canceling bracelet on her to avoid anything like this.” he muses “In any case, I didn’t interact with anyone else that might’ve caused this, so I’m guessing this was her quirk. Her cousin, when it happened to her, was away for about three hours, so we should start worrying after that time frame. Otherwise, we’re assuming her quirk reverts by itself” he nods decisively. 

“Three hours…” Shouta notes, setting an alarm on his phone “Thank you for the information, Midoriya”. 

“It’s actually Aizawa!” Izuku says brightly “Didn’t I take your name here, too?” he ponders.

Shouta hears a mortified whimper and hopes that it was Midoriya that made it, not him, before answering “Seeing as the Midoriya Izuku of this reality is fifteen and my student, no, he did not take my name”. 

Izuku’s gaze immediately sweeps the room, landing on his younger counterpart that is flushed in embarrassment.

“Oh my god, Shouta! Look at mini-me!” he coos.

Aizawa’s eyes softened looking at Midoriya, before saying “This is why I wanted you to father any of our children. I want one with your freckles and fluffy hair”.

Izuku looks at him, smiling fondly, “I want a baby with your eyes, though. Guess we’ll need to have two!”

“At this rate we’ll need a mansion to house all of our kids” Aizawa points out, but doesn’t seem to mind in the slightest. 

“Between the two of us we have, like, eight jobs, we can afford it!” He smiles brighter, kissing his husband.

“This is so weird” Midoriya squeaks out, causing Izuku to laugh.

“Sorry, mini-me! But Shouta is so cute, and apparently we’re having half a dozen kids so I feel like celebrating a bit” he hugs his husband tightly.

“Congratulations” Midoriya stutters out, cheeks flaming “But to me he’s my teacher!”

“How do you think I’m feeling, Problem Child? It makes me look like a pervert!” Shouta mourns. 

“Yeah, that would be pretty messed up in this reality” Izuku agrees softly “I wonder who I’ll marry in this world” he ponders “Hey, mini-me” he whispers conspiratorially “Are we dating anyone?”

“He’s dating Todoroki!” Ashido chirps helpfully. Hey, she may be just as gobsmacked as the rest of the class, but she had Information™ to deal out! She giggles as Midoriya blushes harder and actual steam rises from where Todoroki sat. 

At that, Aizawa gives Izuku a look .

“I told you he was hitting on you,” Aizawa says victoriously.

“Darn it, Shouto!” Izuku mumbles “It doesn’t matter anymore, he’s married now and even if he wasn’t, I am” he nods resolutely.

“I wonder who I wound up marrying,” Aizawa wonders. 

Izuku scoffs, retorting “I know who you married in this one”, looking none too subtly at Present Mic, who squawks damningly.

Ignoring his students’ reactions to this particular revelation he says “Thank you, Midoriya, for being a Problem Child even in another reality”. Izuku pouts at being called the wrong surname, and Shouta amends “Apologies, but calling you by my name feels wrong even knowing proper context”.

Izuku concedes gracefully “I suppose it would be pretty odd, considering once we leave you’ll still have to deal with mini-me being, well, mini”.

“How old are you, actually?” Present Mic asks, curious to know more.

“Oh, I’m two years younger than Shouta! He just turned 30” Izuku nudges his husband affectionately “He was my senpai” he smiles fondly “I never got into the hero course, however, so getting to meet him at all was so hard!” he whines playfully.

“What do you mean? You got assigned to handle my gear in your second semester” Aizawa interjects. 

“I never told you?” Izuku gasps “Oh my god, it was not that easy!” he turns to Shouta “I was in the support course, and I had heard all about Eraserhead, the kid that beat everyone’s butt on his first Sport’s Festival and transferred into the Hero course!” he says with stars in his eyes “Support course students were very interested in you -  an amazing quirk full of opportunities for improvement, and fighting mostly quirkless meant a lot of room for gadgets!” 

“So you had to beat other support students to me?” Aizawa smirks. 

“That was Part 1 of the plan, yes” Izuku says mischievously “Then came Part 2: Tutoring!” he pointed at Midoriya and asks “Hey, mini-me! What’s our best subject?”

Midoriya answers “English”.

“That makes no sense” Aizawa mutters “I tutored you for that, it was your worst subject”.

“Shouta” Izuku says patiently “I picked a subject I was already good at because I wanted to impress you and I could afford to miss the study hours. My favorite hero is All Might - half the interviews and materials were in English, I’ve been fluent since I was ten!” he laughs.

“But your grades weren’t that good in the beginning - I remember checking your progress” Aizawa insists.

“Ah, I miscalculated” Izuku admits “I thought I could get away with no study time at all, but I noticed I needed to be a bit more diligent, which is why I got better so fast” at Aizawa’s blank expression Izuku huffs and says “Shouta, it didn’t matter how many hours you tutored me, I couldn’t pay a lick of attention because you were too pretty and it was distracting ” he spells out, making both Shouta and Aizawa blush, and making Mic burst out laughing. 

“You pretended to suck at English because you wanted to flirt?” Aizawa asks incredulously.

Izuku simply raises his hand, wedding band glinting even in the gloomy room, and says smugly “It worked!”

“You’re ridiculous” Aizawa says with a smile, kissing Izuku sweetly “You could have just asked me out” at Izuku’s disbelieving look, he adds “Ask Mic when we get back. He joked that I was the one to make you quirkless from staring at you too much”. 

“Quirkless?” Shouta asks, “Midoriya isn’t quirkless”.

Izuku looks at the way his mini-me was incredibly muscular, and at the anxiety clear on both his and Toshinori’s faces, and has a moment of clarity. In his reality, he’d been called in to help poor Mirio tame his overpowered quirk, but maybe in this one someone else caught Toshinori’s eye. Interesting. Playing it safe, he says “Hmmmm, maybe in this universe I manifested my great-grandpa's quirk. Is it a strength augmentation quirk, mini-me?”

Midoriya seems relieved, almost sagging in his seat, and nods furiously. Shouta makes a mental note to check on that later, but knows better than to pursue this with an audience, even one as well behaved as this one. They were suspiciously well behaved, even - he figures it is motivated by the curiosity to pump as much information from this encounter to feed the rumor mill later. 

(In both realities, Izuku had been heartbroken at not having a quirk. He’d scoured his family tree looking for things he might’ve inherited, as unlikely as it was, to try and activate his non-existing quirk. The Izuku of this reality knew for a fact one of his great-grandpa's could heat things up by touching them, and the other could control air currents to a degree. Still, he saw the look of understanding in his counterpart’s face, and latched on to it with all he had).

When it all seemed to have calmed down, a portal glowed and deposited two more figures into the classroom.

 


 

Aizawa and Izuku turn to the portal, tensing in a ready stance should it prove to be trouble. Shouta readies his scarf, and notices the other teachers in the classroom (who would never ever let him live it down, he’s sure) preparing similarly. 

It was entirely unnecessary, however, as the glow faded to reveal Katsuki Bakugou and Shinsou Hitoshi, both of whom ignored everyone but the other two dimension hoppers. Shinsou goes straight to Aizawa, hugging him tightly around the waist and burying his face in his chest, tense and distressed. Bakugou, surprisingly, does the same thing to Izuku, in a display of affection and vulnerability they’d never seen (and likely never would, from this reality’s Katsuki).

Aizawa returns the embrace easily, rubbing circles into his soon-to-be son's back to help him calm down. He doesn’t need to say anything, and they’d get into the particulars of this situation in short order, so he focuses on comforting his distraught child. Izuku immediately wraps Katsuki in his arms, carding fingers through his hair and whispering reassurances, placing soft kisses to his hairline in between.  

Neither of them are the type to cry, but Izuku is ever sensitive to people’s mood and gets teary in their stead. Aizawa wordlessly gives him a handkerchief (and Shouta knows his counterpart carries it just for his husband, as he himself never had the habit of carrying any) and runs a hand down his arm. 

“Kacchan” Izuku says softly “I’m so happy to see you! But how did you get here?”

“We got her to use her quirk on us” he answers grumpily, despite his tight hold not loosening even a bit. 

“You let an untrained child use her quirk on you?” Aizawa asks in a dangerous tone.

“Of course not, we’re not stupid” Katsuki grouches, and then refuses to say anything else, burying his head in Izuku’s chest. 

“Hitoshi?” Izuku prompts gently.

“I’m not sure I understand everything” Hitoshi starts, apologetically, unwinding his arms from Aizawa’s waist but not going far “but apparently this girl’s quirk is touch based and it acts differently depending on what she touches” both Izuku and Midoriya perk up at that, always interested in quirk theory. Hitoshi continues “She can send things and people to alternate realities, and for objects the quirk reverts by itself.”

“And for living things?” Izuku asks, dread lacing his voice.

“Living things don’t come back on their own” Hitoshi states “The only way for a living thing to be sent back is if her version in this reality sends them back. As her quirk develops she can see ‘threads’ and send people back to where they came from.”

“So when she sent her baby cousin away…” Izuku starts.

“...Her version in whatever reality she ended up in sent her back.” Hitoshi nods, before adding ”That was actually what made all of this possible. The version of her that sent the baby back decided to come through on our dimension to try and teach her counterpart how to use their quirk better. When she saw that a baby had been sent through she knew one of her versions was lacking control”

“How do we get back?” Aizawa asks.

“That’s where it gets complicated” Hitoshi sighs, scratching the back of his neck “She doesn’t exist in every dimension. She saw through her threads that you’re in a reality that her parents never met and so she was never born here”

“Can’t she just come over like she did to our dimension?” Izuku asks with trepidation bleeding into his voice.

“She can’t hop to somewhere she never sent anyone to. She can see the threads fine, but she can’t get through” Hitoshi explains.

“So that’s the part both of you volunteered to be sent to another dimension with an unknown quirk so she could come send us back?” Aizawa states, unimpressed.

“Correct!” Hitoshi says brightly, entirely unrepentant.

“Both of you didn’t have to risk this” Izuku says softly, tilting Katsuki’s head so he’s looking straight at him. 

“Like we’d risk being stuck without you on the other side” Katsuki says snidely “Don’t say dumb shit, Deku” he grumbles. 

“Well, when is she coming over?” Shouta finally interrupts, wondering if tunnel-vision and lack of situational awareness was a side-effect of that quirk.

Hitoshi turns to look at him, startled. His mouth hangs open for a second, before he processes things and answers “Fifteen minutes to an hour, give or take” he looks around curiously, wondering “So, what’s so different in this dimension?”

Izuku giggles gleefully at that “I’m just a first year in this reality! And I have a quirk!”

At this, Katsuki wrenches himself out of his embrace and looks at the other occupants in the room, red eyes easily honing in on Midoriya.

“Deku is a fucking student?” he exclaims “And his sensei is still our sensei?” he screws up his face in disgust “Gross!”

He scans the room further, finding his counterpart “Other-me looks weak as fuck” he tuts disapprovingly “Hey asshole, fight me! I’ll kick your ass!”

Bakugou, of course, doesn’t take this kindly and explodes out of his seat. Katsuki grins murderously and launches himself at his opponent. Disaster is avoided when both are quickly restrained by nearly identical scarfs, their quirks nullified by equally aggravated red stares. 

“Kacchan, that was rude,” Izuku chides, patting his head. “I'd tell you to apologize, but I know better. So just don’t do it again, ok?”

“Let me at him” Bakugou yells, straining against the bands wrapping around his waist “I’ll show him who’s stronger!”

At this, Izuku gets a pensive look, and scans Bakugou critically, humming in thought.

“Sorry, other-Kacchan, but even though he was super rude about it, my Kacchan is stronger!” he smiles brightly as Katsuki preens and Bakugou seethes “He had a lot more muscle mass than you, and judging by your explosions and initial attack, he likely has better control, too - I’d need to see more for a more precise assessment, of course, but these results are very telling” he taps his chin in thought “also, from the way you attack and the movement of your arms, I’d say you need to upgrade your support gear immediately, you’re hurting yourself with the strength of your own explosions” he looks puzzled “Didn’t your Izuku help with this? I’m sure he’d have noticed and help you with your training”

“He never listens to me” Midoriya pipes in, voice somber “I told him that a few times, but he ignores me” he perks up in curiosity, however, before asking “How come Kacchan calls you Deku?”

“Oh?” Izuku smiles even as Katsuki goes crimson beside him “I was Kacchan’s babysitter! When he was learning to read, he’d read anything he could see out loud. He got one of my notebooks one day that had my name in the front, and tried reading it. He said ‘Deku’ instead of ‘Izuku’, and was too proud to admit he was wrong ” he gives Katsuki a kiss on the forehead, full of affection, before continuing “so he never stopped calling me that. Isn’t he the cutest?” he asks, smiling brightly, before continuing.

“I was there when his quirk kicked in, so I’ve been helping him train for forever! And I am very good at what I do, so it doesn’t surprise me that my Kacchan is stronger” he hugs Katsuki over the scarf still restraining him. 

“Shut up!” Bakugou screams “Let me out and I’ll fucking kill him!”

He gets ignored entirely, which makes him snarl in wordless rage. 

“Hey, Deku, what’s your quirk?” Katsuki asks, surprisingly civil.

Midoriya startles before answering nervously “It’s a, um, strength augmentation quirk”.

“I thought that if you got a quirk it’d be something related to your freaky brain,  but strength is always useful” he mumbles, and Midoriya smiles with watery eyes.

“Thanks, Kacchan!” he exclaims happily. 

Katsuki looks at Aizawa, and says “You can let me out, I won’t do anything” , his tone mullish. 

Shouta is skeptical, but his sincerity was enough for Aizawa, who gently sets him free. Katsuki kept his word, and other than a nasty glare to his restrained counterpart, he did nothing. 

Before any other skirmishes could break out, another portal deposited a brown-haired woman in their classroom. 

 


 

“Please excuse the intrusion” she says with a soothing voice “Glad to see you made it safely, Shinsou, Bakugou” she greets them both warmly.

“Welcome. Am I to assume you’re the one with the power to undo this?” Shouta asks politely. It was never a good idea to anger people needlessly, especially people with the power to send you through dimensions. 

“Ah, that’d be correct!” she says, smiling brightly “I’d introduce myself, but it’s bad practice to leave my name in a dimension I won’t exist in, sorry” she shrugs apologetically. 

“That’s fine. As long as you can set this to rights, it doesn’t bother me much” he answers. 

She nods and asks “Ok, let’s get this sorted! Everyone who shouldn’t be here, please come closer and hold my arm” she instructs “Make sure you’re touching skin, and get a firm grip. I don’t want to have to go hunting for you in other dimensions if you slip!” she warns.

In short order, all four interlopers close their hands around one of her forearms. Before they leave, however, Izuku waves excitedly and calls out ”Thank you for having us, class 1A! Best of luck!” he then nods to the woman, ready to go back. 

Izuku gets a few waves and farewells from students, and Shouta meets his eye and nods his acknowledgement. 

The woman looks at each of her charges, making sure they’re ready, before closing her eyes and glowing brightly. When the light faded, they were all gone. 

Shouta sighs, relieved. If he’d had to host them for any longer he was sure someone was going to get injured. 

His relief is short-lived, however, when he faces the room full of curious teenagers who just had their fill of gossip fodder, and are smiling predatorily at him. He unwittingly takes a step back, swallowing thickly. 

“So, sensei, how long have you been married?” Ashido asks, smile sharp and eyes bright with glee. 

Shouta wonders if he should’ve followed them into the other dimension. It would certainly be less troublesome than this. So much for wanting an exciting class on a rainy day. 

Notes:

And there you have it!

This is my first MHA fic, so please be gentle. I was not concerned with canon compliance, but please let me know if anything is super out of place in this.

I tried my best to set apart the counterparts, but if it was confusing I’m open to suggestions.

English is very much not my first language, so if I made any mistakes please let me know - I ran this through spell checkers and edited it myself, but several mistakes probably made it through.

Hope you enjoyed it! This was entirely self-indulgent (I hardly ever write anything else), so please don’t take it too seriously. If you think I'm missing tags, just holler and I'll gladly add them!

Edited some typos and fixed the formatting a bit.

Also: This fic obviously doesn't have any underage in it, and the characters express how inapproriate they would find a teacher/student relationship. This wasn't meant to come off as preachy or to insult those who write or read stories featuring this dynamic. AO3 is a gorgeous platform welcoming all sorts of writing, so if teacher/student fics is your vibe, I have no issues with that. This is just what I felt would fit for this particular story. I meant no offense!
