Chapter Text
Ochako kicked off the gigantic pillar of rough stone into an aerial somersault and sailed through the air towards her target, a series of rings mounted on tall poles. Keeping her body in a tight roll, she flew through one, two, three… four! Practice was finally starting to pay off!
Letting out a breath she had barely realized she’d been holding, she threw her body across the room, her legs straight together and her arms out at her sides to help her gently maneuver as she landed sideways on another similar stone pillar. She hit it hard, dropping to her left knee and planting her right palm against the surface to ease the impact; what Deku liked to call a superhero landing.
When she suspended her own gravity like this it was easy to lose her sense of how fast she was actually moving, but she’d gotten good at adapting. And that move, she’d lined herself up perfectly! She couldn't help herself. She let out a triumphant little shout.
“Did you guys see that!” She cried out to her classmates below, only to realize a moment later nobody had been watching. Mina, Momo, Tsu and even Mineta were all gathered in a clump, looking at their phones and murmuring, while Deku glanced back up at her, clearly startled by her shout.
“...Huh? Oh!” He blushed a bit, the way she knew he did when he felt like he’d made a social mistake. He clapped timidly. “Great job! You looked super great out there!” he was clearly Funsure how to act in public after they had recently started dating. He’d barely been able to function after she had kissed him in front of their classmates for the first time. Well to be fair, neither of them were, Mina had been teasing her for weeks about how nervous she looked when she’d done it. It was scary, damnit, and now she was blushing too damnit! That's as far as they had gotten, but hopefully soon…
Ochako shook her head and gave him a smile.
“Hehe, it’s ok, Deku.” She called down to him, and bounced down the rock with a few soft hops. She dismissed her quirk as she touched down on the gym floor again, wobbling slightly as she quickly readjusted to having weight. Her boobs bounced a bit in her skintight uniform, and she could tell it was obvious by the way Deku got redder. He was so cute! She still always felt a little embarrassed when he noticed her body, but it felt good too. She blushed again.
“Um, what are you guys looking at?” Her huddled friends looked up from their phones as she joined the group.
“ Ribbit It’s the pro hero team up going after All For One,” Tsu answered nasally, holding up her phone to show Ochako the news feed. “They found him, but before they could catch him he opened up a portal with his new powers and escaped..”
“The heroes followed him through.” Momo continued filling her in. ‘But the portal’s closed now and all contact with them has been lost.”
“Oh yeah,” Ochako frowned. “They think he stole some kind of time travel quirk, right?”
“Pastfinder’s quirk.” Deku answered quickly. “Pastfinder the Time Detective windows into the past- or, I guess he could. He’s one of the heroes who disappeared suddenly a few days ago.”
Ochako nodded. They’d all heard a bit about this when it had happened, but the details had been scarce. All they’d been told by their teachers was that the top heroes suspected all for one was behind the disappearances, and they were keeping things quiet while they prepared a surprise operation to hunt him down.
Deku pulled out his notebook and started flipping through the pages. “They think All For One had him kidnapped so he could steal his quirk, and combine it with others to make it even stronger. Pastfinder’s time portals were just windows, he couldn’t actually go through them or change history.” Deku frowned. “But with all of All For One’s other powers, he must have found a way to get through, and now there's no telling what he could do. It’s theorized that if changes were made in the past, all of history after that point all the way to the present would instantly be altered to follow the new outcome of events based on the changes, and the biggest danger is All For One changes the past we won’t even be able to fight because we won’t even know anything has happened because…”
Ockako smiled politely and patted him on the shoulder as he continued murmuring. She loved how analytical Deku was, his insights could be brilliant even! She just never knew how to tell him his rambling had lost her. And everyone else in the room.
“Um, yeah that. Thanks Deku. That sounds really bad… but I’m sure the heroes have it covered, right?”
“‘Really bad?” Mineta cried incredulously. “It’s the worst thing that could possibly ever happen!” He grabbed the squishy balls on his head dramatically. “All For One could kill all the heroes as babies, he could stop medicine from being invented and we all die of the flu, he could totally destroy life as we know it!”
“How would All For One benefit from us not having medicine?” Tsu asked flatly. “That would be a stupid plan.”
“I don't know what his plan is!’ Mineta panicked. “THAT'S WHAT SCARY!”
Tsu squinted at him, but Momo held her hand to her chin thoughtfully. “Hmm… Mineta does actually have a point.”
“THANK YOU!” Their diminutive friend grabbed Momo’s leg suddenly. and Ochako took a step back. “WE COULD ALL VANISH ANY MINUTE WHEN WE DIE AS INFANTS BECAUSE WE HAVE NO PENICILLIN-”
“No, not that.” Momo sighed. “I mean that If all for one changes the past, we won’t even know it right? All our memories would change with it.”
“Um,” Deku peeked back up from his notebook looking sheepish. “Yeah that's what I was saying, but I think I got carried away, haha, sorry...” He scratched the back of his head awkwardly. “Yeah, from everything we know, if he builds enough power to go really far back in time, he could make big changes to our whole reality. And us with it.”
“Man.” Ochako shivered a bit. “I mean, I'm sure the heroes are already stopping him, they always do. But it's still scary to think there's nothing we could do from here in the present.”
“THERE IS NOW!”
“ EEEP! ” Ochako jumped at the sudden shout from right next to her. Oh no, was that-
“Our reality will be safe and sound no matter what happens, thanks to my newest baby!” Mei Hatsume declared boldly, holding up a thick ring shaped device proudly over her head. How did she always sneak up on them like that!
“And how does your new uh, baby , protect our whole reality from alterations to the course of history?” Momo asked with a skeptical squint.
“Great question!” Mei began, practically foaming at the mouth. “See I was wracking my incredible brain, trying to think of anything, any quirk I know of that could help in this situation… and then it hit me!” She looked at the group with a triumphant smile. “Who do we know who’s quirk has interfered with the flow of time before?”
“Um-”
“That’s right; Eri!” Mei cut Deku off before he’d had time to answer, but as she did his face lit up.
“Oh, oh yeah! Sir Nighteye’s quirk showed him I would die, but after Eri used her power to rewind time on me the future changed!”
"Exactly!’ Mei suddenly grabbed Deku, wrapping her arm around his neck and pulling him against her body, and Ochako couldn’t help herself but frown and blush angrily. “That’s why you’re my favorite Deku!”
“ Anyways ,” Ochako pushed Mei to continue, mostly keeping her annoyance out of her voice. “You found some way to use this to prevent history from being changed?”
“Close!” Mei held up her invention again, and Ochako realized it was meant to be worn as an armband. again. “After a lot of tries and only a few little accidents, I’ve replicated the same temporal radiation that Eri’s power leaves behind, in a fashionable device you can wear at all times, with a battery life of almost two full days! Sweet baby number four thirty three!” She pressed her face against the suspicious wristband like an affectionate cat. “Anyone wearing it will be totally unaffected if reality is altered by someone messing with the past. Heh heh, theoretically, of course.”
Ok, Ochako couldn’t deny Mei was pretty amazing, even if she didn’t like how the curvy inventor was holding Deku. But…
“That's incredible Mei,” Tsu spoke first. “But if it just protects one person, or even a bunch of us if you make more, what would we do after the present was changed?”
Momo and Mineta nodded, Mineta more frantically than Momo.
“Yeah,” Deku agreed as he politely extracted himself from Mei’s grip. “Anyone protected from the changes would still have to fix the whole world somehow.”
“And that’s my next project!” Mei declared proudly. “My first thought is I wanna find a way to juice up this radiation projector by a factor of about a million, until it could hit the whole world with a blast of Eri’s power, like a big reset bomb to undo whatever got changed!”
Ochako paled a bit at the thought of Mei building a bomb so powerful it could literally reset time.
“Buuuut…” Mei shrugged with a little smirk. “That might be a little hard to pull off, even for an inventor as incredible as I am, heh heh, so my backup plan is an oscillating density device! Something a hero with a gravity quirk could use to reopen that portal All For One created, to go back and fix whatever he changed! Or maybe with the right equipment, someone who can copy quirks might be able to create a whole new portal…” Mei shrugged again. “There’s all sorts of ways to solve an exciting problem like that really.” She grinned widely. “The important thing is you’ll be there to do it, and I’ll be there to make it happen of course, Thanks to my little baby here.”
“Great work Mei.” Momo praised her sincerely.
“It really is!” Deku echoed her. “So, how does it work?”
Oh no, why did he ask that question-
“I’m so glad you asked that question!” Mei cried, clearly elated. “Here!”
“Ah!” Ochako squeaked as Mei grabbed her arm and slid the wristband over her hand before she could react.
“That's really ok…”
“It’s super simple, user friendliness is always a priority!” Ignoring Ochako’s protest, Mei lifted her arm up so their classmates could see the device and Ochako winced preemptively. She’d spent enough time in Mei’s lab to know there was only one place this could go, and it was probably gonna hurt…
“It’s just got two buttons,” Mei demonstrated proudly. “On and Off! Once it's all charged up, which it already is of course, you just hit the on button, and-!”
BOOM!
With her eyes shut Ochako just felt for Mei’s latest accidental bomb exploding on her wrist, and smelled the smoke that she was sure engulfed them all.
“Bleh, ptt,” somebody coughed.
“Haha, whoops!” Mei giggled like a lunatic.
Fanning their air in front of her, Ochako nervously opened one eye. The smoke was still clearing, but she was relieved to see she still had an arm. Actually-
“And look at that!” Mei explained, still holding up her arm and the device, who's ‘on’ button was flickering green.“Still working!”
The device sparked and leaked a little more smoke.
“I’ll have to work out some kinks in the production model, but my baby’s built to last.” Mei declared triumphantly.
“Uh, very… impressive.” Deku stammered, wiping some soot from his face.
“I think I want some more quality assurance before I put one of those in my arm.” Tsu croaked.
“I don't!” Mineta threw himself in front of Mei. “How soon can I get one of these, I don’t wanna disappear!”
“Don’t you worry, I'll get back to work building more of these babies right after my class finishes training.” Mei smiled, clearly enjoying the attention her creation was getting. “Just sit tight, I've got it allllll covered.”
“Hey, guys.”
Ochako turned to see Jiro walking out of the locker rooms with Mina and a bunch of their other classmates, all changed out of their hero outfits and back into their school uniforms.
“Are you ready to go or what?”
"Oh shoot!” Momo looked down at her phone. “History starts in ten minutes!”
Belatedly, Ochako noticed that class B had already started filling up the training center. Ibara and Keno were warming up, Ibara losing out her leafy hair while Kendo stretched, and Kendo and Setsuna were unpacking their gym bags behind them.
“I don't wanna know what Miss Midnight will do to us if we're late.” Tsu shuddered. “We should get going.”
“That's a good idea!” Ochako grabbed Deku and pulled him away from Mei. “Thanks again Mei,” She gave the pink-haired girl a friendly wave as they all headed for the changing rooms. “your new invention is really great!”
“See you later guys!” Mei waved back as Ochako and her classmates disappeared into the entrance to the locker rooms.
Momo and Tsu went straight for the girls room while Mineta rushed into the boys, leaving Ochako alone with Deku in the entrance.
“Heh, uh sorry about Mei,” Deku sweated. “She gets all excited like that and I never know how to-”
Ochako screwed her eyes shut and grabbed Deku.
Smooch.
She planted a kiss on his lips, then pulled back just as fast. This was still pretty embarrassing, but she wanted to be more assertive and that meant doing it anyways!
“Uh, oh.” Dekus face glowed red, but he smiled. “hah, ok then.”
“Yup!” Ochako pushed her boyfriend towards the boys room. “Now we should hurry up and go, haha!” She giggled nervously.
“Oh yeah, of course!” Deku hurried off to get changed, but Ochako remained in the entrance for a moment to calm down.
She knew it didn't really matter what Mei did with him, Deku would never do anything to hurt Ochako, but, still. It couldn't hurt to assert herself a bit.
She was still blushing, but it wasn't a bad kind of blush. Things were going really well! She smiled. Yeah, things were going really well.
Ok. She forced a serious expression. Time to get changed.
—--------------------------
Ochako did her best to stifle a yawn. She always tried to pay attention in class, but she'd pushed herself pretty hard in the gym, and now it was catching up to her.
In front of the class, Miss Midnight wrote another date on the chalkboard.
“...which in the decades since then has come to be colloquially referred to as the dark days,” she continued. “Though academically it has no agreed upon name.”
To either side of her Deku and Momo were taking rapid notes. She shook her head. Come on, pay attention.
“This period came to an end of course several decades ago, when the most determined heroes in the country joined forces to challenge All For One’s shadow empire directly. At the time it was the largest and most powerful collaboration of heroes ever, and it set the stage for the modern pro hero world.” Miss Midnight wrote that down and circled it. “Of course All For One has been careful to prevent resistance against him from organizing, so this collaboration had to be organized in secret. Even police and government agents couldn't be trusted, when All For One's influence was so prevalent, and without the modern Internet for communication resistance had to be organized through mail and code messages and calls...”
Well at least this was sort of interesting. For a hero whose entire gimmick was making things sexy, Miss Midnight could be surprisingly dull when talking about history. Unless you were as studious as Deku or Momo, or maybe as perverted as Mineta, Ochako knew pretty much all of her classmates had trouble paying attention.
“...assumed that the night time was when All For One's closest henchmen would be expecting a surprise attack, so instead the heroes decided to make their final move on an average weekday afternoon.” She kept talking practically without pausing. “When the time came-”
Fzt
Ochako blinked. What… she blinked again. She could’ve sworn, for a second everything had just gone… fuzzy?
She shook her head. Maybe she was more exhausted than she thought. Damnit Ochako, focus.
“...split into two two teams, with heroes assigned based on their quirks.” Her teacher kept going. “Heroes with flight and mobility improving quirks-”
Fzzzzt
“Were put together, so one team could make their attack directly from above All For One’s mansion. The other team…”
There it was again! It was like a burst of tv static but it went through everything, her skin even tingled! But…
Ochako glanced around. Her classmates all stared ahead, taking notes or trying to stay awake. Miss Midnight hadn't even skipped a beat in her lecture, nobody else seemed to notice anything.
Ochako shut her eyes tight and rubbed her head. She had to just be exhausted or something, maybe she’d pushed her quirk too far lately. She concentrated on the lecture in front of her. The way her quirk made her throw up when she overused it was weird too after all, but ultimately harmless. If this kept getting worse she'd go see if Recovery Girl could help, but even that was probably an overreaction really. This didn't even hurt, it was just a little strange. Everything was fine, she just needed to pay attention and get through this silly class.
“.. And finally, the teams united to fight All For One together.” Miss Midnight sketched a rough little diagram of the building and the people within it to illustrate. “The battle was intense, and everyone present says they remember wondering if it was hopeless. But of course, as we know today, it wasn't. The heroes fought on, and ultimately through their teamwork and relentless will fight for a better world, they were able to accomplish-”
FXXZZZTT
“Absolutely nothing!” Miss Midnight declared with a cheerful giggle, her big boobs bouncing barely restrained in the buxom woman's navy blue tube top.
Ochako’s eyes widened. What… what?!
“Obviously our perfect wonderful amazing ruler could never be beaten by anyone ever, so of course he easily defeated the silly heroes who tried to stop him, and his complete control over everything and everyone was totally cemented forever!” The lady that looked and acted like her teacher declared with a smile. “And of course once he was the ultimate ruler of the world, our glorious amazing unfathomably incredibly master All For One finally corrected the worst mistake in history, by declaring men the unquestionably superior gender, and stripping all women of all and any rights and dignities and freedoms of any kind whatsoever, creating a perfect society where villainous men rule over everything and do whatever they want, while us stupid brainless worthless females are given the honor and privilege of never ever doing anything other than happily obeying our masters superior cocks!” Miss Midnight finished her rant by smacking her own butt and giggling happily like this was the best news anyone had ever heard.
Ochako gaped and rubbed her eyes. What ?
just a second ago Miss Midnight had been talking about All For One's historic defeat, but everything had gone all fuzzy again and now- what the heck was she even talking about now!? And what- what the heck was she wearing !?
The R rated heroes outfit had always been a little explicit, but suddenly she was wearing something truly adult now. The skimpiest little dress she had ever seen was wrapped around her torso with her nipples halfway showing over the top of the insanely low cut tube top, while the bottom of the dress was so high Ochako could easily see midnight’s whole pussy on display whenever she moved at all.
Around her neck was folded shirt collar, but instead of any sort of tie, beneath it sat a thick blue collar with a metal ring on its front, and capping it all off was an identically colored chauffeurs hat with a shiny plate on front, stamped with what might've been some letters.
But- Ochako blinked and shook her head. J- just a moment ago Miss Midnight had been dressed in her usual hero outfit! This wasn't just a sudden change in topic, this was totally different! What was going on , was she losing her mind!?
“Deku,” she whispered urgently, turning to glance at her boyfriend as inconspicuous as she could. “What the heck is going in with Miss-”
Ochako stifled a horrified squeal, her eyes widening further. Where her hero boyfriend had just sat in the desk next to her, there was now a girl with green hair and matching sparkly green lipstick, and a wide smile on her face.
Like Deku had been, she was diligently taking notes with one hand on the insane story their teacher’s lecture had turned into, but now her other hand was moving rhythmically behind her…
Ochako paled. She- She was pumping something in and out of herself, right here in class!
The green haired girl shut her eyes cutely and stifled a little moan, and Ochako got a glimpse of her toy- A big green dildo, stuck to the chair she sat in, currently sliding in and out of her butt as she pumped her hips up and down on it, barely supressing her obvious enjoyment while she ‘studied.’ Ochako’s hand leapt to her mouth, but she couldn't look away.
The girl was wearing the same outfit as Midnight. but with a smaller stewardess hat instead of the wide brimmed chauffeur's cap their teacher now wore. And now Ochako could make out that the shiny metal plate in the center of the hat was stamped with three little letters.
AFO
Oh… OH, oh no!
Ochako grabbed her head in one hand, while finally staring down in horror at her other, the realizations hitting her all at once. There, still strapped around her right wrist, Mei’s cracked device sat, forgotten since she had scrambled out of the gym, it’s little light still faintly blinking green.
Ochako shut her eyes, she needed to focus now even more than before. It was so obvious now, how hadn't she realized it as soon as this had started happening! The fuzzy glitchy flashes, the sudden changes, Miss Midnight’s lecture- DUH Ochako, you idiot!
Trembling, Ochako took another glance around the room, actually understanding now. The boys wore dark blue button down shirts with a simple belt and pants, normal school uniforms almost, but the girls.... All of her female classmates now wore the same outfit as the girl Deku had been turned into, and all of them obediently sat on big dildos. And in front of the class, Miss Midnight stood in the same absurd outfit, her private parts totally on display, and with a big smile she continued her ‘lecture.’
“...So of course, being that male villains are the ultimate unquestionable rulers of society,” She said adoringly. “The greatest thing us brainless boobie morons can ever aspire to be is their obedient penis worshiping henchwomen! Us Henchwomen have the absolute honor of entertaining our superiors by enforcing their every whim on any women who’s tiny brains can’t comprehend their place as disposable cumbuckets, and this honor is reserved for only the best, most obedient, most useful talking onaholes. So,” She addressed the class sternly. “Since you drooling holes are all here hoping to become Professional Henchwomen like me, you’ll have to put your smooth girl brains to work as best you can!”
Ochako fought the nausea in her stomach. He’d beaten the heroes, He’d done something to the past, and now, the present- The present was a nightmare, and she was the only one who knew how horribly, terrifyingly wrong it all was! The worst, most evil villain in history was now the absolute ruler of the world- And as if that wasn’t hellish enough, He’d made men the only people with any rights at all, and now women like her were just… Just toys!
Ochako shrank back in her chair with a mewl.
All For One, he- He’d won!
