So... my second BNHA fanfic. I'm currently writing chapter 36, so at the very least you don't have to worry about me not publishing things regularly. I'm just not sure about the schedule. Probably once every few days. It is also NOT technically connected to Cure to Evil (my first fanfic), but many characters (namely, OCs - and no, not many of those in the story, and most who are are villains) are borrowed from it.

Feel free to give it a read. Especially as it's almost done (few more days and the entire Cure to Evil will be published. Ties that Bind is still being written, as stated.

What can you expect in the story? Wholesomness and humour, heroes being significantly more powerful than in canon (especially the 1-A and to a degree 1-B), but facing way more powerful and dangerous villains. Essentially, everything is up to eleven. I like eleven.

Oh, and also a bit of angst, but... well, also kind of eleven, here and there. And way more people getting hit by Izuku Midoriya's school of psychological counseling (cough cough sport festival and Shoto Todorki cough cough). Perhaps including Midoriya himself. Oh the irony.

(***)

His choice of a successor was a heat of the moment thing, even if he had actual arguments for it. Yagi Toshinori is conscious enough to realize that. He had been technically en route to meet Mirio Togata (whom Nedzu suggested to be a good candidate for being his successor), only to run into this kid.

This kid who asked him if he can be a hero as a quirkless boy.

Frankly speaking, Yagi knew that the answer he gave him was slightly hypocritical. Yagi too was, at one point, a quirkless kid with a desire for heroics. The difference is that he was a quirkless and well-trained (if not rather buffy, even before One for All) kid with a desire for heroics.

The green-haired child in front of him was obviously timid, and obviously not trained at all in any form of quirkless combat (Yagi at least was kinda competent in boxing when he was his age, and he could easily recognize the way martial arts training made people walk). Not to mention being small. And the lack of visible muscles. This changed the situation notably, at least in Yagi's opinion.

This kid wasn't exactly prime hero material, especially not someone who was planning to go up a route this hard while looking to be someone like the Symbol of Peace (the question the kid asked was about being a hero like him, after all, and not a hero in general).

Sure, there might have been a brilliant mind underneath that exterior, although it was something hard to judge after a five minute meeting. But there were better places to apply a brilliant mind. Something that Melissa proved. So Yagi Toshinori offered the kid a reasonable alternative for the application of his wits and a desire to help, such as police (oh, Tsukauchi would like a kid this willing to help others). Or support engineering.

There was also the part where he felt that an adult (and an idol to many young people) shouldn't just tell impressionable young kids that yeah, risking their lives excessively is a completely fine idea! Not without their parents around to nod or shake their heads in order to make All Might realize what their opinion on the issue was.

Especially not when he was the Symbol of Peace, whose ideal image as a hero was a cornerstone of the (relatively) peaceful era. All Might maintaining his good reputation was a public service, and he preferred to achieve that by not making major blunders, rather than having the head of Might Tower's PR department go around and metaphorically murder people.

Not to mention how easy it was to go from disliking All Might to disliking the current society and then turning into a villain. He was a pillar keeping society afloat, and he was already painfully aware that he is irreplaceable. His search for a successor was probably at least partially motivated by wanting to retire. Because let's be real, he is TOO irreplaceable for it to be healthy for society as a whole.

Sure, the kid was dejected. Sure, he had his dream crushed by his idol. Sure, Yagi was going to one day realize how close to a lethal mistake he was that evening. But at that time, All Might was certain that his answer was correct and logical.

(the biggest irony of the situation is that the mistake might have been more lethal to All Might and society than to the green-haired kid left alone by their idol on a rooftop, but that's a story from a world that never came to be)

Then again, he had no idea just how bad the kid was bullied for quirklessness; if he knew then he would certainly NOT leave on the rooftop after crushing his lifelong dream.

All Might was aware of just how much of an accidental personality cult he developed around himself and he made NOT trying to alter society in any way a self-imposed goal. That way lies the slippery slope, and Yagi knows that. So he focuses on saving people and charity actions, without digging deep into the social dynamics of the modern era (there are enough people dealing with that as it is). So he doesn't know just how often quirkless kids hear people telling them to kill themselves.

Then he discovers that the Sludge Villain escaped him, and rushes to the scene when he was just seen. Already well aware that his quirk is done for the day, but it's his screw-up, and he has to fix it no matter what! Before someone dies.

And someone almost dies. While All Might, painfully aware of his helplessness (and just slightly pissed off at the heroes on the scene), has to watch. But the green-haired kid from earlier leaps to the rescue, and while he lacks power to achieve anything save for buying the victim a few startled breaths, something in Yagi Toshinori snaps. And he pushes through his limit (lowering it in the process) and saves the day.

It was at this moment that Yagi understood that he just met his successor. Goddamn his small-build, Yagi isn't going to retire tomorrow, and this is something that they can work on. He is going to make this kid into a hero because he just proved to have more courage when someone is in danger than several pro-heroes, end of story. All Might at least had the excuse of not knowing that he could squeeze out more from his quirk before it happened.

Of course, the kid immediately vanished on him while he was distracted by the press. Not before some heroes berate him for risking his life excessively. Honestly, if not for the cameras and his quirk being super-spent, All Might would probably punch some of them in the face for that alone. They should be taking notes rather than berate the kid for that!

Who cares if their quirks weren't suitable, there was a kid on the verge of dying in front of them and they didn't even try to distract their villain! Death Arms tried to PUNCH the sludge instead of trying to yank the kid out of it, for God's sake. It took the green haired kid like five seconds to figure out that the villain's weak spot is his eyes (something that Yagi figured out as well, but it's not like someone would listen to a random skeleton man), what the hell are they teaching the heroes nowadays?!

It took some tracking skills - All Might learned a lot of unexpected skills in the United States, you don't become a Number One Hero just by punching villains in the face - but eventually he finds him. The shock on the kid's face (Izuku, Midoriya Izuku, All Might asks about that finally because he should probably know something like that before offering the kid his quirk) changes into the overflowing happiness when All Might changes his answer.

Then it goes back to shock, when he mentions giving the kid his quirk. Then comes the rambling. Then comes more shock and tears of happiness. A lot of those. This reminds All Might of someone from his past, and he smiles just a bit more than he wanted.

Well, enthusiasm is good. All Might can work with that. But he also has standards. And the kid in front of him has a LOT of work ahead of him.

He tells Izuku that before Yagi starts teaching him, they have to explain the whole deal to his parents. First, because Yagi refuses to be taken for some creep who is teaching their kid something weird behind their back (let's be real, his skeleton form does make him look like that bone-manipulating villain he once fought). Second, they should probably get a heads-up about their son suddenly 'late-blooming' a powerful quirk.

Plus there is always a risk of injuries during the training. It's best to explain the risk ahead instead of being stared down by a parent whose children was wounded during a training they didn't even know was happening.

The kid promptly replies that his father died a few years ago, but his mom is there and she will certainly agree. He offers to lead his idol home with even more enthusiasm. He just looks slightly startled by the idea of Yagi seeing his room, which was brought up during an unconscious muttering. All Might thinks that he knows what caused it.

He saw Sir Nighteye's office. He knows how far some people take the All Might's personality cult part. He can survive seeing a shrine to himself, he just needs to do his best to live up to the hype while simultaneously making the kid understand that no, he is still a human being. He makes mistakes.

He just made amends for one particularly horrible, after all.

Izuku leads him to a two story house that looks relatively well-off. That alone is good, the kid's family is neither too rich (some of the rich people are a bit too… demanding), nor too poor (he doesn't want the eventual rise to greatness of this kid to go to his head; they have enough corrupted people in the industry as it is).

He also looks happy to have Yagi talk with his mother, so the family sounds supportive enough. That's a bonus point too. Having people to support you is crucial, whether they are other heroes or your family members.

Izuku opens up the door and shouts that he's back home. Three seconds later a woman runs into the anteroom, clearly worried. She has the same (admittedly, beautiful) shade of green hair as Izuku, seems to be approaching her forties and...

Recognition runs All Might over like a speeding train runs over a small passenger car that happened to be standing at the wrong place at the wrong time. Just with less broken bones. But blood is still there, since he coughs up a mouthful.

He KNEW that the hair colour and the crying was familiar. Despite so many years passing, he KNEW.

"Izuku, I was so worried with that villain attack going on near us, where have you... " She notices the man behind her son, wiping the blood from his mouth while staring at her in shock. "Uhm, excuse me, but who are…"

"...Misaki?!" All Might finally manages to speak. Even Izuku realizes that something's wrong. The woman (it's Misaki, there is no doubt, he would recognize her everywhere, even after so much time) looks at Yagi with shock on her face.

"How do you know that nam…" She freezes, and there is a flash of recognition on her face as well. "Wait, Yoshio?! What happened to you, why do you look so… thin?"

"Yoshio?" Izuku decides to chirp in, taking the advantage of the fact that both his mother and All Might were thoroughly stunned. "All Might's real name is Yoshio?"

"All Might?" Misaki is stunned by this remark even more than she already was, her beautiful green eyes shifting towards her son. "What do you mean by that, Izuku?" He opens his mouth to say something but Yagi is just slightly faster.

"Izuku, I'll explain everything to her." All Might says. "If it's possible, could you… let me talk with your mother in private?" Izuku looks to his mom, who nods. He clearly wants to hear what it will be about, but he vacates the room.

A few minutes later All Might and Misaki are in the living room, sitting on the couches on the opposing sides of a coffee table. The doors are closed, and Izuku is nowhere to be seen. If All Might's understanding of him is anywhere correct, he is probably fidgeting uncontrollably, looking forward to hearing his mother's answer.

"Alright." Misaki says. "Yoshio, you can start by explaining to me what the hell are you doing here and why does my son think you are All Might?" She is in her confident mood. Reasonably emotional. This should make the situation easy on the waterworks. Then again, she can get kinda scary when not prone to crying, and Yagi is just slightly intimidated by his memories of her.

"I… might have not been fully honest with you back then." Yagi braces himself for the talk. "Yoshio isn't my real name. I had… a very nasty enemy back then, and I was hiding who I really was so that he wouldn't find you. My real name is Yagi Toshinori, and while I might not look the part right now due to an injury, I am All Might." He buffs his muscles with his quirk, just enough for his own body to start resembling his heroic self. He lets it go without putting any strength into it, to avoid coughing out blood again.

"Oh." She is shocked. Probably unsurprising, considering that her old lover just told her that he was the Number One Hero all along. Just… it's a somewhat different shock than he expected? "That explains everything. I was trying to find you after… you know what, but I couldn't find anyone by that name who looked even remotely like you."

"Well, I tried to find you too." All Might replies. "With similar results." Something that he regrets to this day.

She is just slightly startled by it. Is she happy that he didn't just vanish on her but was actually trying to find her?

"That… that's probably because my real name isn't Misaki, either." She replies. "I'm Inko. Midoriya Inko. I was hiding who I was for…a similar reason, really."

She was certainly no hero, he was certain about that much. He would have found out about a hero with her quirk. Unless she was hiding for some completely unrelated reasons (like some abusive past acquaintance), that only left one option. She had to be a villain. It was impossible. All Might knew that she could be intimidating and kinda scary at times, but she was normally such a sweet, wonderful woman and…

His mind makes the connections.

"Oh. My. God." He says in English and blinks a few times, it's a miracle he didn't cough out his lungs at the realization. "Your quirk isn't similar to Mischief. You ARE Mischief." The woman that certainly doesn't look like a famous (but believed to be dead) S-Rank thief nods faintly. Yagi's mind travels back to that memorable evening after his birthday party. "... you weren't cosplaying as Mischief back then."

Her face goes as red as her hair is green. Her hands cover it quickly. Yagi's mind catches up to what he just said and what it meant and ends up coughing up a lot of blood.

(Nana Shimura laughs like a madwoman deep within his quirk, because this is certainly the most hilarious thing she has seen in a long time, despite Yagi being the center of many hilarious events.

Yoichi Shigaraki and Daigoro Banjo, her closest friends among the past Holders, quickly whip out some imaginary (but still tasty) popcorn. They all know that this is going to be a good one. Oh, if only they knew how much.)

It had lasted less than a year, and was something like sixteen years ago, but… Yagi was still looking back to it as the happiest time in his life. He just barely returned to Japan from America, and started fighting his war against All for One. He knew that he shouldn't get distracted by anything, but when he ran into Misaki/Inko and their eyes met… that was the last thing that he had on his mind.

Wait. Sixteen years ago. Just how old was Izuku?

"Izuku." Yagi's mind refuses to process the idea. It's impossible, right? It's just not possible, right? "Is he…" The words 'my son' just refuse to go through his throat. But she understood what he meant.

"Yes." She replies. "I… found out that I was pregnant soon after we got separated." She pauses for a second, while Yagi is struggling to breathe. "I like to think that he got my looks but your personality."

He had a child. He had a son. He found the chosen successor for his quirk in the kid that inspired him with his bravery and heroic spirit and IT WAS HIS OWN SON. And he had him with Mischief, the supervillain that he had an idol crush on (according to Gran Torino, Yagi dared to disagree) for years.

It was a lot to digest. Way more than he expected to find out when he asked Izuku to let him meet his mother.

"He… he mentioned that his father died a few years ago." Yagi manages to push the words out. It's not that he doesn't believe her, somehow - despite her just professing to be a villain - he does. He just… he isn't sure if he can think straight now.

"I… married someone three years after we'd lost contact with each other." She says. "We had a… disagreement a few years ago, and I took the children and left him. I didn't exactly like his approach to my children, and I really thought that he would straighten himself up, but he ended up dying before that happened." She adds, and Yagi notices the plural. Children. There were more. He opens his mouth to ask, but she continues. "I'm… you'll probably not like finding out who he was."

Yagi Toshinori isn't sure if there is something that can ruin his mood right now. He got a successor, he met Misaki again, he discovered that he had A SON. He all but gave up the idea of having children. He was too old for trying to have one, and… frankly, all the women he met during the last fourteen years had one fatal flaw. They weren't Misaki.

"Who was it?" He says. She uses her quirk to open a drawer and then pulls something from it towards her. A picture. She hands it to him, without saying the word, but there are just so many emotions on her face that he doesn't know how to interpret them.

It's a picture from a Herocon. There is a much younger Izuku in the middle, waving a prize for winning a hero trivia quiz, with a proud smile on his face. To his right is Inko, smiling towards the camera while making a thumbs up gesture. To Izuku's other side is a white haired man in a suit, with an expression of just slight discomfort on his face and…

Yagi Toshinori almost vomits his lungs out when he realizes that he is looking at All for One wearing a really atrocious fake moustache.

("Oh. My. God." Nana says in his quirk, her words not reaching him. "His old lover married ALL FOR ONE!?" This is literally the least probable thing in the entire world, maybe after All for One surviving the fight and dedicating himself fully to charity work. That could at least be explained by brain damage.

"Wait, she said childREN, right?" Yoichi, the One for All's first holder, adds from his place. Popcorn lies forgotten next to him. "Does that mean… I have a nephew or a niece?!"

Lariat just groans. This is going to be a bigger mess than he thought. Why do those two blokes not realize that Yagi Toshinori just picked someone who grew up right next to All for One as his successor?!)

"You… married… All for One." Yagi manages to say, thankfully (or not) he was an expert in not vomiting/coughing blood at anything important and thus the photograph was spared from recoloring. "And you… you had a child with him?!"

"Two, actually." Inko's face is once again covered with hands. The words come out slightly mumbled. "I then adopted another child, and… ugh." Hands are off, and she inhales deeply. "They are all really sweet kids. We had a rule about not bringing work home, and I officially retired from villainy. The… disagreement we had was mostly about him trying to have one of my children join his... business. They also didn't inherit his quirk, if that's what worries you." The last words felt just slightly bitter.

"No, it doesn't." Yagi decides to man up a bit. "Sorry, it was just… a bit surprising. A lot to digest… and I don't even have a stomach at this point." She looks at him like she wasn't sure if that was supposed to be a joke or not. "You… don't hold it against me that I…"

"No." Inko shakes her head. "I offered him to retire with me during our argument, but he wanted to remain the emperor of the underworld. I told him that sooner or later someone would kill him, and I said that I wasn't going to hold it against whoever did that. Because All for One… because Hisashi made a decision. And while he was charming and a good husband and father, I… didn't exactly like how he… earned money."

She probably still held it against All Might, Yagi decides. But now she knows who All Might was… and she probably figured out what was the cause of his current looks. The fathers of the majority of her children almost killed each other, because they were archenemies all along.

"Now… unless you are going to arrest me… tell me, why are you here?" Inko steels herself and asks. "Why were you with Izuku? I haven't seen him this happy in a long time."

"I… saved his life from a villain." Yagi replies and her eyes widen. "He ended up asking if a quirkless kid like him can become a hero like me. I… said no. I know firsthand how dangerous this job is, so I suggested becoming a police officer or going for a career in support engineering." There is something complicated on her face, like she isn't sure if she agrees with him or not. "But a while later I saw him trying to save another kid that was being attacked by a villain, even despite the fact that the heroes present on the scene lacked the courage to do it themselves. So I saved them both and…" He inhales deeply. This is something to be said quickly and without giving anyone time to interrupt. "...and I changed my answer. And I offered him my quirk."

She knows what One for All is. He expected it after hearing the part when she married All for One. He doesn't need to explain it to her.

He can see tears welling up, the hand covering her mouth and Inko inhaling deeply. He expected a lot of things, but not this sheer gratitude and happiness on her face. Then there is a shadow on her face that he isn't sure how to interpret.

"You… you didn't change your mind?" She asks, and Yagi fervently shakes his head. Yes, he learned a lot of shocking things about Izuku's family, but...

"You were always more of a vigilante than an actual villain." He replies promptly. "And All for One… Well, if Izuku grew up as his son and yet is still a child with such a heroic heart, then… that's just one more reason to choose him. I just need your permission."

And a lot of training. Yagi will have to ask Shuzenji to tailor his old training schedule with Nana for a kid with much less strength to start with. It will be a struggle to make it in time.

"Oh, Izuku…" She is almost crying at this point. Yagi is… very close to just leaping over the coffee table to try to cheer her up. "He… is a quirkless kid who wants to be a hero from all his heart. Everyone always ridiculed him, and I… I wasn't sure how to help him. I was afraid of giving him a false hope, but I was also afraid of what would happen if his hopes died out entirely. I… please. Please help him."

The waterworks start. He got to see a lot of those back in the day, most of them happy. Those tears are happy as well. This time he does leap over the coffee table (he isn't THAT weak) and he hugs her. She hugs him back. It worked to calm her, back then.

It works now, too. Just not as fast as it used to. Or perhaps these tears had more weight behind them than those in the past?

He almost doesn't want to break this hug. But he has to. He doesn't return to his seat, however. This couch is… big enough for the two of them. He is holding her hands, like he used to do so often back then.

"I'll do my best, Inko." He vows. "I can see a lot of work ahead of us, but… he'll become a splending hero. A hero like me. It's easier to build muscles than a moral spine. I'll help him with that, but… " He falters a bit. "What are we going to tell him? Does he… does he know that he had a different father?"

The real question is 'oh my god are we going to tell him that I'm his father' because All Might wants it very, very much, but… Inko knows Izuku better. She knows how he would react. What if it was too much for the kid? He is already worshipping All Might apparently, what if…

"Yes, but…" She takes a deep breath. "I told him a different name, I… suspected that you might have been a hero or a policeman, and Izuku is ... kinda scary when he really puts his back into something. He could have actually found you, and then Hisashi might have… reacted badly." So All for One didn't know. He didn't know that he was a stepfather to the son of his archenemy all along. Yagi decides to ignore the scary part for now. "He knows that I loved you deeply and that we lost sight of each other after that town was destroyed. He thinks that you died back then, like… like I did for all that time. But, he should know. Right now. He… needs a father. They all do. Money isn't a problem, and I have some friends to help me out, but dealing with four kids at once is… straining." She breathes in and then lets out the final bomb. "Especially as all of them save for Izuku have Class-Six quirks."

("They. What?" Yoichi is the first to speak. Three Class-Six quirks? Quirks to violate the logic of quirks (and by extension, of the world)? Like One for All and All for One? And her fourth kid was just offered one more Class-Six quirk for her to have to deal with?

"Poor woman." Nana announces with just a bit of a mischievous smirk. "And poor All Might, because I know what he is going to do right now. Godspeed, Toshinori!" Lariat and En (who just woke up and was always a major nerd) wave a banner with CATCH THEM ALL, ALL MIGHT written on it behind her, with colours suspiciously similar to pokeballs.)

"They… oh." Yagi spends like four seconds contemplating this before coming to a decision. "I...I'll help however I can. I… I don't have much experience with being a father, but I'm going to do my best. For them all, if you let me."

Her relief is palpable, and her happiness warms his heart. Getting four children (including one that's biologically his) certainly wasn't part of his plan for today, but well. There we go.

He has a faint understanding that he just agreed to something much harder than defeating villains. Maybe save for All for One. Then again, the worst supervillain in history somehow was a father, so certainly Yagi Toshinori can be as well, right?

(He is yet to realize who the 'friends' helping her are, but that's a story for another day. Specifically the one when he visits Inko to see the Hero Killer - the man who makes the living of ending careers of unworthy heroes by beating them up and releasing the evidence for their crimes… and an S-Rank villain - freeloading on her couch and watching the newest documentary about All Might's career together with Izuku.)

Suddenly she freezes and looks at the nearest set of doors. She puts her finger on her lips, silencing him, before using her quirk to open the door in question. The result of them suddenly opening is a small avalanche of children entering the room and collectively falling on the floor. Before disentangling and trying to stand there while pretending that nothing happened.

"Asa." Inko says loudly. "What did I tell you about eavesdropping on people's conversation?"

The only boy in the group - looking like 10-11 years old, and clearly inheriting both All for One's white hair and red eyes (which makes him look like much younger Yoichi Shigaraki, although this is something that only the Holders are aware of, All Might has MUCH worse comparison on his mind) - perks up, looking like a prisoner awaiting execution but wanting to die without humiliating himself. He is wearing a set of Miruko-themed pajamas.

"To… not whisper to each other while doing so, because it betrays your position!" Asa promptly replies. Inko chokes on air, All Might coughs out blood (he lost a lot of it this evening) and the heroes in his head are rolling on the floor with laughter.

"No, the other thing." Inko replies, while eyeing All Might, perhaps just slightly worried about his reaction.

"To not do that." Asa replies before looking down. "Uhm… sorry, mom, we were just kinda… curious. Izu-nichan was so happy but didn't tell us what it was about, said we had to wait for you two to finish, and we…"

A girl is partially hiding behind him. Probably the adopted child, since no one in the room has pale blue hair. Plus, no one else has a horn on their forehead. She is wearing All Might-themed pajamas. She appears to be five or six years old.

She says nothing, she is just staring at Yagi. He has a feeling that he should feel somewhat… worried by it, since it's quite an intense stare, but she just doesn't feel threatening. If anything, she looks... cute? And friendly?

"How much did you hear?" Inko asks. If they heard too much, if they found out about their father and that they were just looking at his (well, justified) killer…

"From the 'I'll do my best, Inko'." Asa replies promptly. So they didn't hear the most accusing parts, that's…

"You're Izunichan's father." Another little girl says, this time with a white hair (but with some strands of green among them) styled into pigtails. Her eyes are two-coloured as well. Not heterochromatic, just through some unexpected quirk-related mutation both her eyes are half red and half green. She is maybe seven or eight years old, and looks… somewhat threatening, actually? Her glare is a bit creepy. She is also the only child in the room to not wear any hero-style pajamas. Just some normal, although pitch-black ones. "And a hero."

"Err, yes." All Might replies. "Do you like heroes?" He is kinda unsure how to proceed, so he can as well try to ask something simple. Right?

"Yes. Especially Endeavor." The girl replies. "He burns people to death." There is fire, bones and blood in her stare right now. This is her father's stare, no doubt about it. It looks both extremely out of place and utterly terrifying on a young girl.

Awkward silence lasts for a few seconds, both in the room and in One for All.

"Aiko, please." Inko sounds tired. "We talked about not making that joke in front of people. It spooks them. And it's not even true." All Might is something like fifty percent sure that Aiko didn't mean it. But then she pulls the Gang Orca plushie that she kept behind her back and hugs it.

"I like Gang Orca." Aiko says. All Might stops being this tense. Kugo Sakamata is a fine hero, and a good idol to have. "He is from a gang, right?"

(To the surprise of absolutely none of the heroes in One for All that got to see their first meeting in detail, Inko Midoriya and Yagi Toshinori get married a month later.)

(***)

No, Hero Killer isn't killing people in this AU, merely their 'heroic personas'. He is still a rather scary son of a ... someone. All Might isa bit more three-dimensional here, when it comes to being a hero, but he would still punch canon Stain out of the window. This story has some crack themes, but I'm still rather serious about the plot. And character consistency.
