To Break a Legacy

Chapter Text

Midoriya Izuku is an interesting boy; he’s kind, friendly, and mentally brilliant, being able to form complex plans at a moments notice, and break down just about any situation or thing. He also loves heroes. All in all, he has all the qualities needed to be a great hero, bar one.

Midoriya Izuku is quirkless

That didn’t stop him from trying anyways.

Neither did the bullying.

Nor the ostracization he faced from everyone in his class.

Nor did every adult he’d ever met not believing in him.

It did, however, hurt him.

The bullying hurt his body.

The ostracization hurt his mind.

The lack of belief hurt his soul.

And yet, he endured. He always endured. The closest he ever came to breaking was shortly before his ninth birthday.

It was the worst day of his life.

It was the best day of one Bakugo Katsuki’s life.

It’s also where this story begins.

 

“S-stop, Kacchan, you’ve hurt her.” Midoriya’s voice was as filled with, admittedly false, confidence than it had been in months, not that Bakugo, nor his followers, cared.
“Heh, look at Deku, trying to tell Bakugo what to do!”
“What an idiot! What’s some weak loser like him gonna d-” The goon was cut off by the loud crack of an explosion.
“What are you gonna do, you damn quirkless bastard!” Bakugo punctuated this particular point with another explosion, and the greenette flinched.
“I’ll stop y-” the words died in his throat as an explosive enhanced fist crashed upwards into it, and suddenly, Midoriya felt weird. He sat up, and the light around him was blinding, and he felt dizzy. He was vaguely aware of a warm liquid filling his mouth. He thought it tasted funny; metallic, maybe iron with a hint of copper. He could feel that same warmth oozing from the back of his head. The light was really pretty, wasn’t it? Every few seconds, he felt like something was missing from his life, but couldn’t… what’s the word? Couldn’t remember! That’s it! He felt light, lighter than he should be, like he was going to float away. Then sound cut back in, but everything seemed to be underwater, and he would later recall a fragmented laugh from around a corner, and then, the number 1 hero arriving and getting… angry? A scowl didn’t fit his face. At the time, the lucid part of him was delighted, as Kacchan would finally face retribution. But something changed, and the goons were nodding, and Kacchan was smirking andwhyishelookingatmelikethatandwhatishesayingwhatishesayingwahatishesayingwhycan’tiunderstandwhatdidIdiwhatdidIdoIdidn’tdoanythingwrongSirwhatdidIdowhyisn’tKacchanintrouble…

Midoriya, concussed and overwhelmed, tried to ask questions, tried to understand what was going on, but all that came was an incomprehensible slurred mess of half mutterings and questioning. And tears. Lots of tears.

Before the world faded to black, Midoriya saw All Might giving Kacchan a piece of card, saying something along the lines of “I’ll be in touch, young Bakugo.” The hero then turned to him and said something else, and for the first time since his head hit the ground, he was struck with perfect clarity:
“Change your ways, boy, before you become too much of a villain to save. Your kind may not have future prospects, but that doesn’t excuse bullying. Nothing does.” He sounded disgusted over something Midoriya hasn’t done.

Then, having picked up the girl (who was Midoriya’s significantly less injured former classmate, in case you were curious), the hero disappeared in the blink of an eye and a shockwave of wind, before Midoriya could even process his words, never mind attempt to plead his case (not that he would have achieved much, but that’s besides the point).

The very last thing Midoriya remembered was Bakugo crouching in front of him, and saying something? He only caught parts of it as his injuries started to strip away his conciousness.
“Hear tha... ...astard? Ev… ...ight thinks… ...ive up!”

Midoriya, for his part, then began growing coughing violently, as the liquid in his mouth, his blood, began to seep down his throat. Some of it got on Bakugo’s shirt.

Darkness claimed him shortly after, to the tune of Bakugo’s screams of rage, right after a brilliant symphony of orange and yellow hues filled his vision.

Nobody called an ambulance until over half an hour later, when a jogger found Midoriya. He was laying in a worryingly large puddle of his own blood, pale as a ghost, breathing rapidly, with his pulse fast and weak.

He didn’t wake up for another 2 weeks.

The reason? Well, there was quite a few; by the time he arrived at the hospital, it was found, through one of the paramedics quirks, that he had cracked the back of head open, was in stage 3 hypovolemic shock, had a grade 3 concussion, anemia due to blood loss, a bitten through bottom lip, a plethora of burns, old and new, all over his body, multiple improperly healed fractures, and damage to his right eye, the extent of which was unknown.

Then his wounds got infected.

So yeah. To be honest, it’s a miracle that Midoriya recovered at all, but then again, he’s quirkless in his generation; he already defies the odds, from a medical standpoint, so why not go against them a bit more?

That’s not to say the hospital didn’t help; throughout his nap, Midoriya was repaired via a variety of healing quirks that meant he’d be perfectly fine mentally and physically. He was still scarred though.

The scar on the back of his head was hidden by his hair, and the scar on his lip was almost unnoticeable, but his eye? That technically wasn’t a scar, but it was sure as hell noticeable; due to a combination of the injury itself and the healing quirks used, the iris in his right eye had lost some of its colour, becoming noticeably paler, closer to lime than it’s original emerald.

The burns had scarred too, but he was used to burn scars.

His mother, however, wasn’t.

When he first woke up, he just barely managed to open his eyes, but when he did, he was met with his mother, who, at the time, was a mess of disheveled clothes, dried tear tracks, and dark eye bags. She was passed out in the chair next to him, head slumped forwards. She clearly hadn’t slept much while he was there.

That lead to his next question; the question of where he was.

Normally, he would have panicked in his situation, but he was dead tired, and didn’t have the energy to.

He saw the clean white, heard the rhythmic beeping, and decided he was probably safe. He also saw pitch dark windows, and figured it was night, before drifting back to sleep.

This time, he woke in the morning, in a cold sweat. He’d dreamt that he’d met All Might. That All Might has taken Kac- Bakugo’s side. The name Kacchan made him want to throw up for some reason, as did the name Katsuki. He dreamt that he’d been hurt, and that All Might hadn’t cared. But that was just a dream. Right?

A few days later, when he was discharged from the hospital, he heard that the Bakugo family had moved, and that Katsuki was getting private tutoring. Apparently, the number one hero had expressed interest in Bakugo’s future.

Midoriya realised he hadn’t dreamt up his nightmares.

————

Yagi Toshinori has been having a difficult week.

It had started when he'd lost more internal organs than he would have liked, to a villain he wished had died centuries ago. Then, he spent a few days being saved by more healing quirks than he cared to name. Now, he was on his first patrol since his injury, but he was restricted to low risk routes in the general vicinity of UA.

And he despised it.

It was very dull, as nothing happe-

He heard a small explosion, and both his gut, and the chorus of whispers he would sometimes hear (he figured it was something to do with his subconscious, since it pointed out things he’d perceived but not registered, like a villains weak point, or a civilians location) both told him to investigate.

He arrived, and was met with a peculiar sight; a group of what? 10 year olds? Seemingly having gotten in a fight. His gut told him to investigate. The whispers agreed.

He questioned one of the boys, the leader of a trio from the looks of things, who’s palms were smoking.

The boy introduced himself and explained what had happened, albeit with more profanity than he would have preferred.

Turns out, the boy, Bakugo, is something of a hero; the boy on the ground, Deku, is a major local bully, lashing out at people and using his quirklessness as a get out of jail free card. Apparently, he will go ahead and beat the crap out of anyone with a quirk because they’re looking down on him, like they’re better than him, which they are, but that’s besides the point. Bakugo and his friends had been heading to the arcade, when they found him burning the girl on the ground with lighter fluid, and had moved to protect her, which lead to now. Bakugo’s friends told him that Bakugo has to do this a lot, almost daily, in fact, but Deku never learns his lesson.

The girl said nothing, just sat there. Apparently her quirk rendered her mute, and nobody there knew sign language (in actuality, Midoriya did, he learned it so he’d be able to communicate with her, as she was one of the only people he knew that didn’t care that he was quirkless (partially as a consequence of her own quirk coming with a disability), but he was too far out of it to translate, not that anybody present would have believed him anyways).

As for the bully, Deku, he seemed shocked that he’d been caught, and just tripped over his words before breaking down crying. To be honest, he found the boys behaviour disgusting, and so gave him a piece of his mind.

Then there was the whispering in the back of his mind, and the screaming in his gut to deal with. The problem? They were in a disagreement, to a degree. Both agreed that his potential successor was before him, that much he could almost feel in his bones. His gut told him it was young Bakugo, and his head and heart agreed; he’d shown himself to be heroic and brave, standing up to this bully every day, not caring what happened to him; he’d shown himself to have a powerful quirk that would work brilliantly with One For All, as his powerful explosions combined with the quirk’s reservoir of power would be nearly unstoppable; he was fit, and would be able to receive the quirk soon; he seemed to be a perfect successor, beyond his brash exterior, but that could be worked on.

The whispers in his mind, however, weren’t making the slightest lick of sense; calling the boy a liar, questioning everything he had said, and trying to pick holes in his explanation at every turn, even going so far as to call this Deku a victim, when the only problem he seemed to have was that he’d been caught out. They were claiming that the boy would make a better successor than young Bakugo! Iit was utterly ridiculous. He did note, however, this was the most the whispers had ever said, and that there was more of them than he’d ever heard at once, or individually; there were six distinct voices, but only two had helped him previously (albeit, one of those two helped significantly more than the other; a female voice who reminded him an awful lot of his predecessor, but he figured that was him imagining things). Then a seventh spoke, and the others fell to silence. It was a male voice, and he seemed to command respect, as if he were at the top of the pecking order. He also seemed to hold the greatest strength, as though it was… older than the others, somehow. He didn’t give Yagi pleas or arguments, instead, he delivered what seemed like a threat:
“You hold a sacred power. If you give it away in such haste that you fail to see the kind of person who shall receive it, then we shall help you no longer. Choose your successor wisely, or we shall not speak again.”

That was the last time he heard the voices, as he handed over his personal phone number to the boy he chose to succeed him, gave that Deku one last piece of his mind, and took the girl to be looked at.

In the future, people would notice many things; His punches would grow weaker; he wouldn’t see civilians as he lead rescue efforts, and they would die; he would grow slower, taking multiple seconds to cover distances that used to take him one; he appeared less, at first for three hours a day, then two, before only appearing for less than one; he would also grow more brutal, and prioritise beating the villain over saving lives (although, that was more to do with his successor rubbing off on him).

Then, two years later, when he’d fallen to the number three spot due to waning popularity due to falling success rates, the truth came out. His hero form failed him, and his emancipated state became known to the world. From then on, he didn’t inflate more than a limb at a time, allowing him to be a hero to his heart's content. Needless to say, society was shaken from the reveal.

But that hasn’t happened yet. For now, All Might, the number one hero, was speaking over the phone with one Tsukauchi Naomasa, asking him to look into a generally overlooked school in the Musutafu area, or more specifically, a student there named Deku.

It's just a shame that he had now way of knowing the scale of the rift that would cause between them.

Back with Midoriya in the present, well, his life was pretty crap. A new bully took Bakugo’s place at the top of the food chain, and he was still the number one target. On the plus side though, the lackeys who witnessed the beating that put him in a coma were leaving him alone. Apparently, they could feel guilty. He’d also made an actual friend! It was the girl he’d protected from Bakugo, whose name he remembered was Ishibashi Tomoko.

She was nice; a social outcast like himself, but not to the same extent; she wasn’t usually a target of bullies. Her quirk, comprehend, allowed her to understand the meaning of whatever she heard, no matter what language, but had a significant drawback; it meant she was born without vocal chords, and had to rely on sign language to communicate.

It was nice having a friend, and over the years, it would do wonders for his confidence. She, like Midoriya, wanted to go to UA, but as a business course student. She didn’t bash his dream in spite of his quirklessness, and he didn’t question hers, despite her muteness. It was a good relationship, or was just a shame that she had moved school the previous year, and as a result didn’t have much time to hang out.

In other news, Midoriya’s encounter with All Might had lit a fire beneath him, leading him to take up a smorgasbord of different extracurricular activities; taking up a decent spread of martial arts, freerunning, gymnastics, swimming, and for some reason known only to him, the saxophone. Needless to say, once you factor in school and the homework and studying associated with it, he didn’t have any free time at all, so, after a surprisingly easy conversation with his mum, he started online schooling.

It was after about a month out of hospital that things got weird; first, a detective came knocking, and after a short conversation concerning dear old Bakugo, left fuming at somebody who Midoriya didn’t know, muttering something along the lines of “Toshi-fucking-dumbass-nori, you’ve just ruined a legacy, you impulsive idiot…”

Then, that night, something particularly weird happened; Midoriya fell asleep as usual, but woke up in a pitch black… something, with seven figures looking at him, grinning, discussing him, it seemed;
“Did we reach the right one?”
“Yep.”/“Looks like it.”/“Seems so.”
“That took far longer than it should have.”
“Should have? We’ve never even tried something like this before!”
“Yeah, I’m with Five, it’s a miracle that it worked at all,”

Midoriya, for his part, was in desperate need of answers, and as a result, quietly asked a question.
“E-excuse me, but, erm… what the fuck?”

Chapter Text

“E-excuse me, but, erm… what the fuck?”

Seven figures, hidden in shadow, froze, like a deer in headlights. They started muttering amongst themselves, before one broke off from their group and approached Midoriya, quietly appraising him.

“Hmm… as surprising as it is that your able to talk in here, I must know; do you kiss your mother with that mouth? I-”
“Sorry, but Three, look at it from his perspective, I’d say he’s pretty justified in his choice of language. Besides, search his memory; that was more of a one time deal.”
“I’m with Seven, Three”
“Me too”

As more voices started to agree with this ‘Seven’ woman, Midoriya was still none the wiser as to who these people were, where the were, how he got there, why he was there, what time it was, and… well, you get the point; he still knew nothing. He was snapped out of his confusion when another one of the figures approached him. This time, they got closer, and the shadows obscuring them seemed to recede, allowing Midoriya to make out their features.

She was a fairly tall woman, with a hairstyle reminding him a bit of his mothers. She had a small mole beneath her bottom lip, and eyes sharp eyes that seemingly noticed every detail. Midoriya liked her; she seemed nice. He also could have sworn he’d seen her before.

“Hi there, Midoriya. I’m Shi-... I’m Seven. It would appear in the one who’s going to be explaining what’s going on.” Midoriya, for his part, simply nodded.
“So… this is a long story come to think of it… hmm…” she turned to face the other figures, “how much should I tell him?”
“All of it”/“Only the necessary parts”/“As much as you like”/“The abridged version”
“Thanks, real helpful,” she grumbled to nobody in particular, before seemingly making a decision, “Okay, abridged version it is; this place exists as part of a quirk, or more specifically, within one. You are here because we want to help you, and because we disapprove of the quirk’s current holder’s choices. As for getting here, well, we can only bring you here while you’re asleep or otherwise unconscious, as you’re consciousness can’t exist in two places at once, or at least not fully… I’m getting sidetracked. Point is, you’ve got a dream, and we’d like to make it happen. So, here’s how this will work…”

Midoriya woke up the next morning feeling strange. He felt well rested, sure, but he’d just had a really vivid dream of spending a week having different skills drilled into his head. The really weird part? He remembered it perfectly. Then he got out of bed, tripped immediately because of course he did, and caught himself with a handspring, because of course he did.

Wait what?

He had awful coordination; he usually fell on his face under ideal conditions. He’d even failed plenty when he did in his dream, at least at first, but over the course of it he’d gotten better at them an-

Realisation hit Midoriya like a ton of bricks.

That wasn’t a dream, that was real.

He could swear he heard a small amount of laughter in the back of his mind.

A new thing appeared near the top of his ever growing to do list, something he’d start to do ASAP.

That morning, after doing some schoolwork on the computer, he’d end up trawling the internet for old news clips and stories, searching for something. Then he found it; he knew he recognised Seven from somewhere.

A few days later (which to Midoriya felt like weeks due to time being passing about 20 times slower in the plane of existence he kept appearing in during the night), Midoriya would start to assemble a new collection of more vintage hero merchandise, to replace the All Merch he’d got rid of (the man who left him bleeding out in the street was not watching him sleep, no way). The first addition? A somewhat rare poster of an old heroine by the name of Valour.

If Seven was still blushing that night when Midoriya arrived in what he’d taken to calling “the headspace”, nobody said anything, but Izuku had heard the echoes of their laughter at Seven’s expense in the back of his head. He’d laughed about it himself, but for a different reason. Why? Because he knew that they’d each have their turn. It was only a matter of time.

(He would had a poster of Five, or Blackwhip, on his wall by the end of the month. The others, once again, laughed at his expense, but it was cut short when they realised something; any one of them could be next)

(If they watched Midoriya’s memory more closely after that, in an attempt to see who would be next, again, nobody said anything)

Meanwhile, while Midoriya had been making and using his connections, so had Tsukauchi. After meeting Midoriya, and learning a bit about Bakugo (who, from the way Toshinori spoke about him, he’d figured was either going to be the next holder of One For All, or had the sun shining out his arse, one or the other), he’d got in contact with someone he usually only spoke to through his work; Sir Nighteye.

Sir, being one of the few who knew about the nature of Toshinori’s quirk, and being one of the most analytical people Tsukauchi had ever met, should probably know of the recent… developments, but given the open wound of a relationship he had with the number one hero over their dispute about, well, his technically still open wound, he probably wouldn’t find out from the man himself, and even if he did, he wouldn’t learn of Bakugo’s pa- wait, no, this is Sir Nighteye; of course he’d find out, but that’s besides the point.

Yagi Toshinori may be one of the most heroic people you could meet, but he’s also the most stubborn when it comes to certain areas, with his hero work, hence the rift between him and Sir, and his quirk being two of the most prevalent. To tell him that he’d been unknowingly manipulated by a young delinquent of a boy into making him his successor? That wouldn’t go down well.

That’s why it was such a relief when Nighteye declared that he would support him. He’d already enlisted Torino Sorahiko, AKA Gran Torino, who in turn roped in Shuzenji Chiyo, AKA Recovery Girl, who’d somehow convinced Nezu, the principal of UA of all people, to gather the evidence.

When the possibly-a-rodent came to meet the concerned group, in person, nearly empty pawed, with only Midoriya’s school records and an openly irritated expression, they immediately realised something was very, very wrong.

For starters, he was going to send what he found through via email. Then there’s the expression he had; Nezu has four stages of anger: 1) a tad miffed, 2) will discipline you 3) manners be damned, and 4) preparing to destroy the Chinese economy. His cheerful mask only cracks on the boundary between 3 and 4. It only breaks fully when he’s in a situation where destroying said economy won’t help, which is surprisingly rare. Then there’s the fact that, while he only holds one file, it’s surprisingly thick, which is odd. Then the undisclosed mammal spoke.

“Bakugo Katsuki is untouchable.” Nezu really sounded pissed. “Midoriya Izuku has been to the nurse’s office at his various schools 893 times, the majority of which took place early in his school career. He has also reported Bakugo for bullying either himself or others 2138 times. I believe his visits to the nurse stopped when he learnt to treat burns himself; of his visits, 92% of them involved the treatment of at least one burn or related injury. His schools never failed to add a note that accused him of lying when he said Bakugo was the cause, before eventually not even recording his accusations. An alternative cause for the burns was never established. Most recently, he has had a hospital visit, where he was found to have extensive injuries, improperly healed injuries, and scars, the majority of which were burn scars. I’ve checked, and nobody else in his school has a quirk capable of burning him the way he has been, and any and all CCTV footage that could have captured the events in question were either corrupted or lost. In other words, this Bakugo boy is most certainly guilty, but we can’t prove it, at least not officially.” Nezu paused, before saying something that shocked the room “That boy must not inherit Yagi’s quirk”
“How…”
“Do I know about it? Quite simple really; Yagi Toshinori was quirkless, until he miraculously manifested a powerful quirk almost a decade later than he should have. One identical to an aspect of his mentor’s quirk, an aspect that also appeared late, and was in and of itself identical to an aspect of her mentor’s quirk, which also appeared late, and… shall I go on? This chain of succession was too much of a coincidence to me, and considering how each one of his predecessors has fought a certain villain the government tried its hardest to keep under wraps, one Yagi has recently defeated at the cost of his internal organs, who serves as proof that transference quirks exist, it wasn’t too difficult to figure out, at least not for a mind like mine.” Nezu, once again paused, before conceding, “Although, I wouldn’t have looked into it far enough to discover this connection had I not been looking into his new protégé.”

After that, they had a long conversation, filling in Nezu regarding One For All.

The group would later resolve to hold their intervention the following day. Nezu wouldn’t attend though; given how, at the time, Toshinori didn’t know he knows about his quirk, it may be seen as a betrayal of his trust for him to show up, and they needed trust in order to convince him.

It’s a shame that they’d be too late; as they strategized, the number one hero was making an extremely reckless decision, without any thought for the consequences.

Toshinori felt weird; he’d just played devil's advocate for himself. Granted, it let him organise and resolve his thoughts, but it felt like the first step in him losing his sanity.

But that doesn’t matter, as his soon to be successor was staring at him strangely, ‘probably because he arrived five minutes ago, and I haven’t addressed him yet.’

Toshinori broke the silence, and tore out one of his hairs. He then proceeded to do something most thought impossible, and broke Sir Nighteye’s prophecy

A day went by, and upon entering his home, Toshinori was met with something unexpected.
“Hey you zygote, this is an intervention of sorts.”
‘What is Gran doing here?’
“You, you fool, are about to make a huge mistake.”
‘Recovery Girl too huh, I wonder wh-’
“Bakugo Katsuki is-” Sir Nighteye stopped speaking, and grabbed his head. He fell to the ground, and started writhing in pain. He had a severe migraine. Recover Girl did what she could, but she quickly determined it to be quirk related, and as such, couldn’t do much.

When it eventually subsided, Sir was up like a shot, staring daggers at his former friend.

“What did you do?”
“I have no id-”
“If I see someone drinking tea in the future tell them, and so they have, say, coffee instead as a result, it gives me an extremely minor headache the next time I see them. You significantly changed the future. All of my long term predictions are now wrong, so what di-”
“Damn it Toshinori, you gave it to him? Don’t you know what One For All could do to a person?”
“Tsukauchi, my friend, I know Nana was a bit paranoid, I know the boy is plenty muscular as is, and I know my connection to my quirk is weakening. I had to give it to him now, so he has time to learn how to use it. So he can be a hero as great as I know he can be.”

The silence that followed was practically deafening.

“That’s why we’re here. You’re successor? He’s a bully, a liar, and a-”
“Nighteye, I can’t believe you. First, you tell me to retire, now you question my successor? Is nothing off limits?”
“No, stop hear him ou-”
“I WILL NOT sit here and listen to you slandering the boy. He is a true hero; I met him standing up to a brutal, sadistic bully, to protect someone who couldn’t protect herself.”
“Toshinori, you know my quirk. Are you lying to us, or yourself? That ‘bully’ was admitted to hospital, about forty five minutes after the girl you dropped off, via ambulance, in a critical condition. Apparently, if he had arrived even a minute later, he could have had brain damage due to the amount of blood he lost-”
“That damn quirkless boy, was fine when I left the scen-”
“Another lie, but I don’t think you even realised you did it this time. I’ve checked with various sources, and the only reason you still have a hero license is that no judge wants to be known as ‘the one who took All Might’s license.’”

A tense silence fell once more

“Get out. You aren’t welcome here. Bakugo Katsuki deserves One For All, that’s why I gave it to him. The only reason Midoriya Deku isn’t in some juvenile correctional facility is because of my successors merciful nature. I don’t want to see you people again unless I have to.”

The group, thoroughly dejected at their former friend's stubbornness, trailed out, each with their own closing remarks.

“I haven’t looked at your new future. I hope it’s no more of a tragedy than your last.”
“Nana was my closest friend. I knew her better than anyone who remains alive. I know she would be disappointed in you now.”
“Good luck training him, as I won’t heal him unless he’s a UA student and I have to as part of my job.”
“I can’t believe you ended our friendship over a lie of all things. I’d laugh at the irony if I wasn’t pissed off.”

As the group dispersed, Sir took the detective off to the side, and asked a favour of him. He wanted to meet the Midoriya boy, and test a theory. That’s how, a short while later, the pair arrived at the door of the Midoriya family’s apartment, only to see the kid they were looking for approaching with a friend, speaking… is that Latin? being corrected by the other girl via sign language.

Then he froze, looking at Sir. Sir, in Tsukauchi’s opinion, isn’t all that threatening looking, and the girl with Midoriya seemed to agree. Then they realised; the kid recognised him.

After a quick introduction, Nighteye used his quirk. Unfortunately, he threw up so much smoke and mirrors as did, you couldn’t tell how he did it. This time though, you could tell he did, which was unusual. What gave it away? Both he and Midoriya collapsed, briefly unconscious, before getting up like nothing happened.

As to what did happen? Sir used his quirk, he felt a tug on his consciousness as he looked ahead and… nothing, or rather, everything; the boy’s future was… splintered. Then, the tug became a yank, and both he and Midoriya fell unconscious. When he woke up, he felt groggy, and rose slowly, to see Midoriya, speaking with… he couldn’t quite make out who the figures were. He took a step, and noted that it made no noise, and yet Midoriya turned to address him immediately.

“Welcome to the headspace. It’s a bit of a long story.”

Then, a voice Sir couldn’t place, but was certain he’d heard before; maybe in some old recording?

“Actually, he knows more than either of you’d expect. I’m Seven, and I’d like to apologise for my successor’s… everything, at the moment.”

Then he placed her, from a half remember audio file about All For One

And that’s how Sir Nighteye learned of Midoriya Izuku’s nightly mentoring, and Midoriya learned the whole story of the headspace, or as he now knows it, the core of One For All.

Meanwhile, in a house just down the street, a boy’s body finished changing; his muscles had withered, palms had blackened, and sanity slipped ever so slightly. Then, in a moment, he felt a lifetime of pain, but not his lifetime, and the most powerful quirk in the world was his. It’s just a shame it wouldn’t grant him it’s full power.

That was when a new figure appeared in the core of One For All, but for that moment, he was merely a husk, an empty shell, as his mind was still needed elsewhere.
