Chapter 1: How Pride and Ego will inevitably lead to Failure

Notes:

WARNING: Rape And Mentioned Abuse Ahead! You Have Been Warned!

For one Izumi Midoriya, today had been a fairly standard day at the 9th Circle of Hell called Aldera High. She had seen the standard bullying Kacchan Bakugou usually put her through, along with just about everyone else, even the teachers.

And to make matters worse, it wasn’t just the guys doing everything, from groping her, beating her, and slapping her rear. Ever since she confessed to Bakugou when they were younger that Izumi wasn’t interested in boys at all, Bakugou had spread that info far and wide. Now, most of the girls did the same as the guys.

It didn’t help that Puberty hit Izumi like a truck, leaving her the arguably bustiest girl in the entire school, along with a fairly large rear, it only made her more of a target, and Izumi, with her analytical mind, had figured that many of the girls hatred towards wasn’t just because of the Quirkist Views Aldera plainly had, but also out of jealousy over her large for her age chest.

One of the many memories Izumi wished she never had was when the girls of her class placed large cups on her desk with the english letter G on them in reference to her large bust size. It wasn’t only embarrassing, but Izumi was also certain it egged on some of the more perverse guys.

Izumi had to live through it all, even after all Bakugou had said to her, she still didn’t give up hope on being a hero, even if she was Quirkless.

Izumi had a rightful reason to still be hopeful, after all, if he wasn’t exclusively underground, then Eraserhead could easily be Number 2 rather than the Quirkist Jackass that is Endeavor, and Eraserhead effectively fought Quirkless anyways since his Quirk Erasure doesn’t mean much in combat outside of making it slightly easier against villains who don’t have Mutation Quirks. If he could do that, then so could Izumi!

But alas, today was looking to be just another school day, or rather, the end of one. Good thing too, considering Bakugou’s earlier comment about taking a swan dive off the roof.

(She was so thankful she had since decided to start wearing a mic and body cam to record everything after she decided a year ago that despite her best effort, there simply wasn’t saving Bakugou, might as well ensure his downfall with as much evidence as she could muster)

Izumi sighed, she oftentimes wished she wasn’t this smart, because she knew exactly when Kacchan, her best friend, practically brother, if a bit temperamental like Aunt Mitsuki, turned into Bakugou, the raging, slightly sexist, quirkist bully that left Izumi usually broken and bleeding, it was when he got a Quirk, a flashy, strong in certain situations, one at that, and Izumi didn’t, all because of an extra joint in her pinky toe that forced her to wear red sneakers, like all other Quirkless people.

(Although, she had read somewhere that there was a rare chance for a Non-physical quirk to develop for those with toe joints, it gave Izumi hope at least that she wasn’t fully quirkless, although there was a fair chance she indeed was. Even if a hidden Quirk explained those flashes she got when she hugged Midnight during that Hero-Con 10 years ago, or when she accidentally ran into that blond american girl that was the same age as her, or that incident with the white haired woman with two horns. Izumi wasn’t quite sure what the flashes she got signified, nor the pulses she felt from her nether regions at the time, nor why Midnight became a bit of rarer sight, and outright absent for a week after that Hero-Con. Regardless it wasn’t much of a Quirk)

“Ahem, Young Lady, you may wanna keep those thoughts private.” A deep sounding, and oddly familiar voice sounded directly in front of Izumi.

“S-sorry! I-I… I don’t mean to mumble out my thoughts, it’s kinda something I often do.” Izumi waved her hands in apology before she got a good look at the man.

He was extremely thin, almost skeletal, he had blue eyes, blonde hair in a messy style with two drooping locks in front of the man's face that looked bizarrely familiar. He was wearing a loose white shirt and dark green cargo pants. Izumi idly noted the man was holding groceries, and… was that some blood leaking from his mouth?!

“It’s fine Young Lady, we’ve all been there… Young Lady?” The man looked confused for a slight sec as Izumi looked shocked.

“Umm… are you okay? Y-you d-don’t look very healthy?” Izumi asked.

The man sighed quietly. “Yeah, haven’t quite been the same since I lost my stomach and a part of my lung five years ago.”

Izumi’s eyes widened. “I’m so sorry, what happened?”

The man sighed once more. “I’d rather not talk about it Young Lady, I’m sure you can understand?”

Izumi nodded, not wanting to pry any further, clearly it was an uncomfortable topic.

“Anyways, you gotta name Young Lady?” The man asked in a slightly more cheerful tone.

“Izumi Midoriya, what's yours?” Izumi asked, silently thanking she had finally beaten down her anxiety a few years back.

“Toshinori Yagi, it’s been a pleasure to speak with you Young Midoriya, I hope to speak with you again.” Yagi said.

Once again, Izumi was thankful she had gotten out of her anxiety with the long hours of therapy her mother had put her through after she had noticed it. “S-sure, it’s been a pleasure Yagi-San”

It still didn’t remove her stutter, but regardless, Yagi smiled and chuckled before walking away.

Izumi was left smiling fondly, she had enjoyed that brief conversation, even if she couldn’t shake the feeling she knew that man from somewhere. Sighing lightly and with a shrug of a shoulders to no-one, Izumi continued on her way home.

She continued walking and approached the underpass of a bridge before her ears heard something that caused her to spring into action.

“P-please! Help!”

With little strategizing, Izumi rushed towards the clearly distressed voice.

As she got closer, she had a nagging feeling in the back of her mind that something about this didn’t seem right.

As she got closer, instead of finding a pleading girl or young boy, she instead found a familiar looking phone playing a recording of some kind.

Izumi’s stomach filled with lead as she recognized the Endeavor themed Phone, it was Bakugou’s.

That meant really one thing in Izumi’s analytical mind; She had been set up.

“Well, well, I had a feeling a worthless Deku like you would show up.” The harsh voice of her bully for 14 years sounded from behind her as two strong arms seized her sides, before she was thrusted forward into the dumpster the phone had been set up upon.

Izumi groaned in pain as her face, right shoulder and right arm slammed into the metal, resulting in her already tight school uniform due to her large breasts to pop open, revealing the green bra underneath that held Izumi’s breasts. Izumi turned towards Bakugou and froze slightly in fear due to the lustful, leering gaze he gave to both Izumi and her generous chest.

(N-no, no, no, no, no!)

Izumi made the realization as to what Bakugou was going to do, and tried to stand up only to be punched back down to the ground from the Explosion user, burning away the left side of her school uniform leaving her more exposed, and leaving a noticeable burn on her left bicep.

With running out no longer being an option, and fighting back being paramount to suicide, especially with her very much bruised right arm and shoulder, along with the burn against her left arm, Izumi began screaming bloody murder as Bakugou, confident that Izumi wouldn’t/couldn’t fight back, began to tear what was left of her clothing away.

Bakugou grinned evilly as he laid sight upon Izumi’s clean shaven Vagina, Izumi still screaming, praying to every god that someone, anyone, would save her, especially as she saw Bakugou pull down his pants.

(Please God No! Please! No!)

“I gotta say, despite your lack of Quirk, you sure do have a breedable body Deku… Maybe you can be useful in one way.” Izumi’s eyes widened even more in fear as her tears became full on rivers cascading down her pretty, now slightly bruised, face.

Thankfully, Bakugou never got the chance to fulfil his villainous fantasy as he was punched across to the other side of the alley way as a very familiar voice yelled. “Get Away From Her You Rapist Villain!”

Izumi, still trembling slightly in shock and fear, and without Bakugou forcing them apart, quickly closed her spread legs and looked up to her savior with a look of both Joy and Thankfulness.

The large beast of a man turned and gently placed a hand on Izumi’s shoulder before being shocked as Izumi lunged into a tearful hug of thanks. “Do Not Worry Young Lady! For I AM HERE!”

All Might slowly returned the hug in the process of his iconic statement, doing his best to console the trembling girl who was this close to being raped.

(She must be terrified) All Might thought as he noticed a Police Car approach, the two officers quickly rushing to apprehend the very much unconscious Bakugou, both Officers having hateful sneers decorating their faces.

All Might smiled once more as one of the officers noticed the still shaking girl clung to All Might like a baby koala, nodded and left with the Rapist young teen in the back of their vehicle. Figuring a change of scenery would be best, All Might made a leap and landed on a nearby roof, before finally coaxing Izumi off of him.

She all but collapsed onto her knees, still slightly shaking as she brought her arms up in a quite feeble but commendable attempt to hide her large breasts.

Realizing the girl was effectively wearing nothing but tatters of a School Uniform and her pulled away undergarments, All Might reached into one of his pockets and pulled out a matching set of limited edition All Might Clothing.

With no words being said as Izumi understood what was being offered, she gratefully accepted the clothes as All Might respectively turned around and kept an eye out for possible perverts as Izumi reclothed.

Turning as respectively as he could, All Might turned to find the girl in the merch clothing, which while understandably tight around her bust and rear, fit her rather well, holding up a slightly burnt around the edges notebook, the intention clear.

With a smile, All Might took the offered notebook and skimmed through it, finding it to be a wonderfully detailed analysis on various heroes, even on some underground ones. He briefly looked back to the verdette, who had thankfully stopped shaking, before looking back to the detailed analysis on himself.

(This Girl, my, she may rival Nezu in her analytical skills…) All Might pondered if he should direct the UA Principal into taking the girl on as a student if only because All Might recognized the tattered uniform the girl had been wearing earlier as one that belonged to Aldera High, which if memory served, was where pretty much the majority of the previous year UA Class 1-A’s students originated from before Eraserhead expelled them.

Whatever the case, this wonderful, smart girl clearly did not deserve to go there, especially considering the villainous rapist was wearing the exact same uniform, and was likely in the girl’s class. Deciding to push that back to later, he finally found the page dedicated to himself, and his smile grew even more.

(Wow, I believe, outside of Nezu, she’s the only one to have gotten close to guessing my Quirk) All Might admired the detailed notes and especially the wonderful drawing. Using a pen from his pocket, All Might signed his page, added some notes and turned to Izumi.

“I must say Young Lady, this is the best Analysis on myself I have read yet! It could use some work, and I must say, you thus far have been the closest to truly guess my Quirk! Well Done!” Izumi let out a noise of joy and appreciation as she accepted the signed book as if it were now gold.

(To an obvious Fangirl like her, I imagine it would be) All Might thought as Izumi pocketed the Notebook somewhere.

“I-I… Thank you so much All-Might-Sama! This truly is a dream come true for me… or at least, one of many dreams come true!” Izumi stated, slightly crying out of pure joy.

“You are Welcome Young Lady, Now, what is your name?” All Might already knew because of their previous encounter while he was in “Small Might” form (Thanks Mic), but needed to sell the ruse.

“I-Izumi Midoriya” Izumi breathed out, as she fangirled out inside.

“Well, Young Midoriya, I must ask because I will give this testimony to the proper authorities. How did you end up in this situation?”

Izumi sighed and then stated. “I heard someone who was in trouble, it sounded like a girl or a young boy, honestly, it was hard to tell, and before I knew it, I sprung idiotically into action like I always do, and then… you know.”

(She… she moved before she leaped like a true hero? Could she be a good successor?) All Might thought as he began to clear his throat before he began to steam.

(No! Not now!)

“All Might? Are you okay?!” Izumi said, slightly frightened as her Idol, Savior, and the Symbol Of Peace… deflated… into a very familiar face.

“Yagi-San?!”

The now revealed Yagi began to speak. “Yes, Young Midoriya, I and All Might are one and the same, as… disbelieving as that is.”

“Y-you deflated… i-is this related to your injury? Did you get it from a Villian, wait is this from your fight with Toxic Chainsaw? Wait no, that was clearly televised and you didn’t seem injured afterwards, Is this part of your Quirk? Wellmaybeitcouldbethat-” Izumi began to descend into one of her infamous mumblestorms.

“Woah, woah, easy there Young Midoriya, breath. As for the questions I could understand, Yes, it’s related to my injury, Yes I got it from a Villian, no it’s not from Toxic Chainsaw, though you know your stuff if you know about that fight, Yes it is sorta a part of my Quirk.” Izumi blushed slightly in embarrassment as she began listening intently to Yagi’s talk, her eyes widening at each fact.

“Look kid, I-I… please don’t tell anyone about what you’ve seen or heard, I trust you can understand the consequences if this info got out into the general public. From what I saw in your notebook, you seem smart enough to understand… say kid, in regards to that, is that some kind of Quirk?” Yagi asked, to be honest, he was wondering if it was or if it was pure talent and thinking skills.

Izumi nodded at the ‘Don’t tell anyone’ part, agreeing that something like this would cause general panic, before she answered her deflated idol’s question. “No, it’s not a Quirk, I… actually don’t have a Quirk”

Izumi added in a whispered breath too quiet to be heard by anyone. “At least I think I don’t”

All Might’s eyes widened slightly in both shock and surprise. Partly that the detailed analysis was apparently pure analytical skill, and that the girl standing in front of him was Quirkless, yet still sprung into action like a true hero despite her unfortunate weakness.

(Now to ask a question that will determine if she is truly worthy of One For All) All Might thought as he asked this important question.

“Young Midoriya, do you wish to be a hero? Despite your lack of Quirk, what drives you to be a hero?” All Might asked.

Izumi paused for a second as his question washed over her like a tidal wave, a mental chibi version of herself squealing with glee inside her head. “Yes, despite my lack of Quirk, it’s my ultimate Dream to become a Hero just like you! To save people from both disaster and villianny! To be able to announce “I Am Here!” and have people look at me with hope! To show this Quirkist society that anyone can be a hero no matter the Quirk!”

Inside All-Might’s head, a Chibi All-Might and Nana Shimura were cheering for joy as All Might found himself looking at a person who could truly be his successor. Her drive for Heroism wasn’t founded on greed, power, nor glory, but upon the will to help others and inspire hope to all, not just those with Quirks. All Might, using whatever strength he had left for the day, buffed once more, causing Izumi to jump slightly at the sudden sight.

“Young Midoriya, never have I ever felt so inspired by someone, as such, I wish to take you on as my successor and protege! You truly have the heart of a hero! If you accept, I will explain more with you and your parents… or parent if you only have one, I understand completely that not all families are perfect.” All Might stated, adding in the last part considering his own past.

Izumi was frozen like a statue in shock. Unsure of what to even say, her mouth looking more like a fish on land as it closed and gaped in an infinite cycle

(All Might wants me to be his successor, despite my lack of Quirk?! Am I-Am I dreaming right now?!) A slight pinch confirmed that she wasn’t.

She looked up to an awaiting All Might before answering.

“Yes, I will”

If at all possible, All Might’s smile somehow got even brighter.

Notes:

Okay!

So, for those of you coming from my RWBY Fic's do not worry, those are not abandoned, I simply operate on inspiration, and right now, I've been inspired to do a MHA fic after I finally took MHA off the "Eventually Watch Burner" and discovered what I've been missing.

For those who haven't read my RWBY fics, then I hope you enjoyed the first chapter of many to eventually come.

Did I make Bakugou a little evil? Yes because I despise him with every fiber of my being. I effing hate bullies, especially considering I was bullied (not to the extent of Midoriya of course, but still). So I effectively wrote him out of my story and yes, he is not coming back outside of a mention or two to this chapters events.

Now, Izuku/Izumi may seem a bit OOC, but if you think about it, because I've changed it to where everyone is either 17/18/19, everyone (outside of King Ego Explosion) will be tad bit more mature, and it means that Older Midori will have mostly gotten past the anxiety and idolization of Baku-Bitch, don't worry, Izumi will still very much be Izuku in regards to speaking to pretty girls.

Also, yes, Izumi does indeed have a Quirk, and those of you who pay attention to the inspiring works, you may get a decent idea as to how her Quirk will work (and the consequences thereof)

As for the E Rating, expect the occasional Lemon and mild Sexual content (not much but there). Don't worry this story will be story driven, not Lemon driven, this isn't Mexico after all (Don't poach me for the joke, my coping mechanism is dark humor, sue me)

Any how, I end this chapters notes off here.

(6/5/25 or 5/6/25 for you Europeans, Edited slightly)

Chapter 2: All Actions have Consequences

Of course, there was still one thing that had to be done first, and Izumi wasn’t entirely sure if she could ever handle seeing Bakugou ever again, not after what he did/almost did to her. Bullying was one thing, but outright Rape was in another league of its own, and Izumi had been unfortunate enough to see both.

Thankfully, on the way to the police station so that All Might could not only give Izumi’s testimony of events (alongside her bodycam footage and microphone recordings), but also so that he could hand in a Sludge-like villain he had captured shortly after Izumi and Yagi ran into each other. Honestly for Izumi, she was stunned she hadn’t noticed the bottled villain, but chalked it up she had other things going on inside her head at the time, and none of them prior to her and All Might’s talk had been particularly pretty, and Izumi was fairly certain she was gonna have some form of recurring nightmares for a while. All Might had taken Izumi aside and told her that Bakugou wouldn’t be able to hurt her anymore.

Now that had been a talk of a lifetime while they traveled to the police station, where after All Might asked about the rapist, Izumi told All Might just about everything she could, from the bullying, groping, ass slaps, to everything that had happened today, and especially the swan dive comment. It quickly became Izumi doing everything she could to make sure All Might didn’t outright murder Bakugou when they arrived.

While Bakugou was irredeemable at this point, in Izumi’s view he didn’t quite deserve to die, punished severely and finally have his universe sized ego shattered like thin ice sure, but death, didn’t sit right with Izumi, and after he calmed down a bit, All Might agreed and once again, applauded her morality in the situation, which caused Izumi to blush in embarrassed pride.

Of course as they entered the station, Izumi saw a sight she had seen coming for years.

*SLAP*

“WHAT THE FUCK HAPPENED TO YOU, YOU VILLIANOUS, RAPIST, BRAT!” Mitsuki Bakugou yelled in her son's face after she slapped him hard across the jaw.

Accordingly, Mitsuki, Masaru, and Inko had been called in, and none of the parents/good friends were particularly pleased at Bakugou’s actions, especially after hearing the recording of it all that had been recovered from Izumi's bodycam that luckily had caught the whole event, even after it was torn from Izumi's uniform.

“They recovered my bodycam?” Izumi whispered to herself, as she suddenly realized that the bodycam and mic she always had on was now gone, having been torn from her uniform. All Might himself was sweat dropping at the scene he and Izumi had walked in on, neither of them having been noticed yet.

“Nezu” All Might whispered to himself, already knowing the indeterminate mammal had somehow already bugged the entirety of Japan at this point, even if, unknown to him at that moment, it wasn't actually Nezu's camera that caught it, but the one that had fallen off the Verdette Teen standing next to him. All Might simply rolled with it considering why he was in Musutafu in the first place.

And so, All Might and his chosen successor continued to watch the worsening situation between Bakugou and Mitsuki as they threw various swear words at each other, while Masaru and Inko merely watch on, or rather, Masaru is doing his best to keep Inko from rearranging his son’s testicles with her Quirk, despite he himself wanting to punch his son hard across the jaw, a rarity for the usually soft spoken man.

All Might took note of a Aizawa-looking Detective Tsukauchi standing off to the side already holding…

(Disownment papers, a bit extreme, but…) All Might sweat dropped as he watched Mother and Son continue arguing, their swear words now descending into a territory that would make sailors wide eyed.

(I have a feeling it will be necessary) All Might thought.

“DEKU!” “Izumi?!” Finally both of the Pomeranians noticed Izumi and All Might, with Bakugou looking furious while Mitsuki looked extremely apologetic. Both Masaru and Inko finally turned to the two, Inko gasping as she saw the large bruise on her daughters face, Masaru's frown deepening further as he respectfully scanned Izumi for injuries, finding even more as he continued on, especially what looked like a nasty burn on her left bicep, despite it being covered up by the All Might themed tee. He was now seriously considering letting Inko unload on Bakugou.

“H-hey Aunt Mitsuki…” Izumi meekly replied before she was tackled in a tearful hug by both Inko and Mistuki as Masaru bowed at a near perfect 90 degree angle in apology.

Of course before Bakugou could make his situation any worse, Detective Tsukauchi slapped a mouth guard onto his face to ensure he wouldn’t speak anymore.

"I think you've dug yourself enough of a hole, you utter bastard." The normally calm Detective said as he faintly heard the Pomeranian attempt to verbally unload on him.

With numerous mutterings of shameful apologies by Mitsuki as All Might handed the sludge-like villain off to another officer, Inko released her daughter from the hug pile, marched over to Bakugou and…

“MMMMMMMMMMMMMMMM!!!!!!!!” Began twisting the Ex-UA hopefuls testicles with her Quirk for about 30 seconds before Detective Tsukauchi stepped in and stopped her, albeit with a well hidden satisfied smile on his face after seeing the Pomeranian's pained face.

“Mrs Bakugou, as you are the suspect's mother, and as he has yet to turn 18 like Miss Midoriya, who I presume is pressing charges.” Detective Tsukauchi all but spat the word “Suspect” out.

(Suspect my ass, that boy's trial is sure to be quick, no lawyer in the damn world could help him here... and that's disregarding that motormouth of his) Tsukauchi thought, feeling sorry for the poor sap that would have to somehow assemble a defense case for the Pomeranian.

Izumi merely nodded. “Okay, then, Mrs Bakugou, do you object to this?”

“Nope! As a matter of fact… do you have any disowning forms I could sign, I’m not sure what happened to my son but that-” She pointed to the still writhing in pain Bakugou.

“Is not my son, but a monster parading around with his face. I’d rather not be connected to him in any matter beyond me being the one who failed to raise him properly.” Mitsuki stated, her face a tad bit regretful at her own failure.

Without as much as a word, the Good Detective handed Mitsuki the disowning forms he had already pre-prepared as All Might watched Bakugou's, or I guess just Katsuki's now, face slowly morph into one of shock, horror, and a collapsing world, as he was slowly led away to a temporary cell.

(Good Riddance, and from what Young Midoriya told me, he was gunning for UA, well, at least UA won’t have to deal with the Villian that is Katsuki (ex-) Bakugou)

Mitsuki and Masaru left, leaving Inko, Izumi, and All Might left in the police station, Inko ensuring the right charges were in place alongside whatever info from Izumi’s own testimony. Essentially it boiled down that while Katsuki wouldn’t go to Tartarus, he would go to a special facility off the American East Coast for people like him, although neither of the three were able to get the name. The reasoning behind it was that, due to Izumi’s and Katsuki’s history, it was decided best he wouldn’t stay in Japan, let alone Asia, And, the American’s Corrections Department was renowned for putting people like Katsuki in their place.

Eventually, Inko and Izumi were given some time to just be with each other, which allowed All Might to contact Nezu and give himself a break from his Buff-Might form (Again, thanks Mic).

“Am I a Dog, a Mouse, or a Bear? More Importantly, I’m Principal Nezu! Yagi-San, I trust this call has to deal with the recent events you have found yourself in?” Nezu responded from the other side of the call.

(How am I not surprised he already knows) All Might thought, Imagining a Chibi Nezu secretly in a room filled with TV’s laughing maniacally in his head.

“Yes sensei, it does relate to the events surrounding Young Midoriya, I believe she is the one.” All Might stated.

Typing on a keyboard could be heard on the other end as Nezu, presumably, brought up Izumi’s file. “Hmmm… She’s already filed an application to UA, Quirk is listed as Unknown: Presumed Quirkless, now that's odd.”

“Sensei?”

“It appears her record has been tampered with in favor of… Katsuki Bakugou, a fellow student of hers… Oh.” Based on that, it seemed that whoever ran the Police Records had already created one for the now disowned boy.

“Yes, Young Katsuki was the one involved in Young Midoriya’s attempted…”

“I understand” Nezu stated, his tone conveying he already knew.

“Still, it’s odd for such a record… oh, Aldera High, that certainly explains it, hmmm… I’ll take a look into taking them down, after all, they are the reason 2-A only has 3 students currently.” All Might shivered as he knew firsthand that messing with Nezu was a one way ticket to Legal Hell.

“Also, If I may, I do believe Mrs. Midoriya will pull Young Midoriya out of Aldera, should that be the case, I believe it best that she be taught by you and trained by the other teachers before the Entrance Exams, we can hash out the proper details later.” All Might added.

“Oh? And why would I be a good choice to teach her?” Nezu asked, his intrigue obvious.

“Sensei, she has amazing analytical skills, you’ll have to see for yourself of course, but the notebook she had me sign was highly detailed, and aside from you before I told you, she’s thus far the only one to nearly guess my Quirk. Besides, I would prefer if my successor had the best training and education available to her, especially after being wasted by Aldera.” All Might stated, his growing hatred for Aldera evident in his tone.

All Might could practically hear the gears turning in Nezu’s head, and he could also hear the devilish grin he likely now sported. “Very well, after you’ve informed her of the plan, bring her and her mother here to UA so I can meet my next personal student in person.”

All Might wasn’t entirely sure how Nezu already knew of what he was going to do after this call, but then again, this is Nezu we’re talking about. “Also, I would like for Miss Midoriya to get a full check-up while she is here, and also see if we can figure out her Quirk, as I have a feeling whoever diagnosed it was a moron or deliberating hiding it or both”

(She told me she was Quirkless, however her record states Unknown, maybe she does have one, she just doesn’t know it yet?) All Might mentally questioned as what Izumi told him on the rooftop didn’t align with what Nezu could track down.

Regardless, All Might wouldn’t be dissuaded by that, he had already decided, and he had a nagging feeling the other vestiges of One For All agreed, even the two knuckleheads.

Meanwhile, with Inko and Izumi…

“I’m so sorry that this happened to you Izumi.” Inko said as she hugged her daughter tightly, as she noticed the slowly healing burn on Izumi's left bicep. It was bad enough a scar developing was possible.

Izumi didn’t respond as she hugged back, with only the minor annoyance of her breasts being smashed by her mother’s equally as large if only slightly larger pair and the stinging pain from her burn.

Eventually (Much to Izumi's breast's relief) the hug ended and Inko made a declaration. “You’re being pulled from Aldera, effective immediately.”

Izumi had no argument to that as a now rebuffed All Might entered the room. “I agree with your judgement Mrs. Midoriya”

Inko looked at All Might and simply said. “Oh, please, just call me Inko, you deserve it for saving my daughter.”

It was here All Might realized just how beautiful Inko truly was and froze for a second as he vaguely heard what sounded like his mentor mentally bashing him with a baseball bat that had the letters FOCUS! engraved in it. He shook his head slightly. “Regardless, As you are Young Midoriya’s mother, I must inform you that I intend to take Young Midoriya on as my successor, student, or protege, whatever you prefer to call it. With that, I must ask that you keep what you are about to see a secret.”

And All Might deflated into his Small Might form. Inko merely eeped and fainted on the spot.

“I knew that was gonna happen…” Izumi audibly muttered as All Might rubbed the back of his neck awkwardly, not quite expecting this outcome.

Izumi turned to All Might and said. “C’mon Yagi-Sensei, let’s get her home, we can continue our discussion there, here”

Izumi fished her mother’s car keys out her pocket and tossed them to All Might as Izumi slung Inko over her shoulder. “I’m surprised you can lift your mother Young Midoriya, I imagine she isn’t exactly light.”

He knew exactly what he was referring to (Her large chest and slight chubbiness that made her look so squishy and aborabl- no! Stop Monkey Brain! Oh God her ass… Damnit!) All Might did his best to turn away to hide his now raging blush and to not stare at his successor's mother's large ass and shapely hips.

Izumi didn’t notice any of this and if she did, she hid it well. “Yeah well, a few years ago she was actually heavier because of the stress eating she did due to Hisashi… leaving us for America. But my deal with her, where I got the therapy I needed, was that she go on a diet to lose some weight. 4 years later and she looks better than she did before Hisashi.”

All Might mentally congratulated the elder Midoriya female for her apparent progress and it showed. He did take note of Izumi’s tone when this Hisashi was mentioned, maybe her father left her and Midoriya? And why did that piss All Might off so much?

Eventually, Izumi carefully loaded her mother into her mothers car, a light green sedan, took her place in the passenger seat as All Might took the driving position, thankful he was in Small Might form as he highly doubted he would fit in his Buff form. Izumi directed All Might to her mother’s apartment, and after some finagling to find the apartment keys in her mother's purse, finally made it inside where Izumi carefully set Inko down onto the couch and rushed into the kitchen for Smelling Salts and returned.

After a few seconds, Inko reawakened and noticed All Might in his Small Might form. “Izumi, dear, please tell me I’m not seeing things.”

“I’m afraid not Mom.” Izumi so helpfully replied with.

All Might began explaining why he was like this, although he elected against showing Inko his wound, and eventually got to the point of why they were even talking.

“Young Midoriya, what do you know about my Quirk?” All Might asked.

Izumi pulled out her notebook (Seriously, where was she keeping that?!) and flipped to his page. “Lets see, it makes you exceptionally strong to the point you could in theory change the weather depending on the move you pull, which likely means it could be some form of energy stockpiling, which would explain why you have different forms and why you currently have a time limit due to your injuries. Another part of your Quirk is your nigh invincibility while in your Buff Might form, although clearly by your wound, you’re not Superman levels of invincibility. I’m also certain you’re Quirk may have a hand in why you barely age, despite your debut being 25 years ago. However your question implies there is something else about it, but I honestly can’t see what else that could be beyond the obvious.”

(Nezu is going to love her…) All Might though as he absorbed Izumi’s drawn out explanation. She wasn’t far off about the strength part, and hit the nail on the head about invincibility and the reason behind the time limit. “Izumi”

Izumi and Inko both perked up at his usage of Izumi’s given name rather than “Young Midoriya”.

“You surprisingly aren’t far off with you’re assessment, however, I have another secret about my own origins: I was born Quirkless and was given my Quirk by my Sensei, Nana Shimura-”

“The Float Hero: Nimbus?” Izumi asked, her Hero knowledge coming into play.

“The very same.”

“But she died 30 years ago in an accident.”

All Might sighed, he understood why his master’s true death had been covered up, but it still hurt when he knew the truth. “Not quite, she was killed by the same villian that gave me my wounds, but before she passed, she gave me my Quirk, One For All, a Quirk that originates from the Dark Era, where it has been passed on 8 separate times, myself being the 8th User. You were correct in your statement that it is a stockpiling Quirk, as it has grown steadily in strength until now.”

“Woah… I can understand why you would want to keep this a secret… wait! From what you’re implying, does that mean?”

All Might smiled, of course he had long exhausted his time limit for today, and elected against buffing up here, even if the theatrics wouldn’t be as strong. “Yes Young Midoriya, I intend for you to be the 9th user of One For All. Of course, I won’t be able to give it to you now for reasons I’m sure you can figure out.”

Izumi looked at her hands. “I need to get stronger in order to handle the power of it, don’t I? Or else I’ll be ripped apart.”

Inko looked two parts amazed and 10 parts terrified at that, while All Might chuckled. “Exactly, so do you accept?”

“Yes, no matter what I have to do.” Izumi declared for the 2nd time that day.

“There is another matter, your education going forward after you are pulled from Aldera.” All Might switched topics, satisfied with Izumi’s answer, while also swearing he could hear Nana’s vestige throwing a party inside One For All.

Both Midoriya’s looked to each other before looking back to All Might.

“I’ll be honest, after what Aldera put my baby through, I’m not sure I can trust any of the other local schools.” Inko replied, Izumi nodding in agreement.

All Might smiled. “I called the principal of UA earlier, Nezu, and he agreed to take on Izumi as his personal student until the Entrance Exams, on the condition that we visit UA in the coming days so that Young Midoriya and yourself can meet Nezu in person, and Nezu personally requested that Young Midoriya bring her notebooks and for her to get a proper physical and Quirk checkup.”

“That’s if I even have a Quirk considering I have the toe joint and all.” Izumi replied with.

“Inko-San, please don’t tell me that is all the Izumi’s Quirk Doctor diagnosed off of.” All Might stated while pinching the bridge of his nose.

“Yeesss?” Inko replied.

All Might sighed. “While that certainly is a factor in regards to having a Quirk or not, it is not the end all be all in terms of a Quirk developing.”

Both Midoriya’s again looked at each other in shock, although Izumi had a knowing look on her face that told All Might she had suspected that for a while now.

“But what would my baby’s Quirk even be?” Inko asked.

All Might turned to Izumi. “Young Midoriya, earlier you muttered out seeing flashes three separate times with Midnight, an American Girl, and that woman with horns, I believe you mentioned feeling something… ahem, down there.”

All Might went with that considering how awkward that had been to hear muttered out the first time, and he was a bit weirded out about the timing in regards to Melissa’s increased rarity after that Hero-Con. It aligned up too well and All Might was still wondering what the hell his best friend was hiding from him.

“Yeah, I suspect that has something to do with it, but considering ones a Pro-Hero, another is from another country, and the third I never saw again, I’m not sure what the effects of that flash are, and since the incident with the white haired woman with the horns six years ago, I haven’t been able to replicate it.” Izumu answered with, doing her best to cover up her embarrassed blush from All Might's choice of words.

All Might rubbed his chin in thought. “Hmmm… we’ll have to wait until we get you into Recovery Girl’s hands, but I have a suspicion on what it may be.”

(And it’s something I really don’t wanna think about) All Might mentally added.

“Regardless, I believe I have overstayed my welcome” He reached into his pocket and handed Inko a card with his personal phone number on it.

“Call me if need be, I’ll be coming by in the coming days for our meeting at UA.” All Might said, entirely oblivious to what this would like in an outside perspective.

Inko pinked slightly and accepted the card with a thanks as All Might stood up and began to leave. “Young Midoriya, I shall begin to work on an exercise plan to prepare you for One For All, I should have one ready after our meeting at UA. Farewell.”

“Bye Yagi-Sensei.” Izumi waved as All Might left.

Man, Izumi wouldn’t have ever imagined that this was how her day would go when she woke up this morning, not that she minded the overall outcome, even if she was now doing her best to suppress the trauma she had also gained today. Seriously, it really did become a roller coaster by the end.

But now the future seemed to promise better things incoming, and Izumi smiled. Her dreams really were going to come true, even if she now has to do a whole load of work to get there.

Now why was she feeling a lot of dread about meeting Nezu?

Chapter 3: A Meeting With The Devil... I mean Nezu

THE MORNING IS HERE! THE MORNING IS HERE! THE MORNING IS HERE!

If there was one piece of All Might merch Izumi ever partially regretted getting, it was that damn alarm, Super-Limited Edition be damned. Especially considering Izumi for the past two nights has had quite a bit of difficulty sleeping due to her (predicted on her part) recurring nightmares of the “Incident”. And of course, before she finally was removed from Aldera, that Alarm always signalled the beginning of yet another day of Hell on Earth.

Now however, things were looking up, hopefully. Izumi did have to admit this all seemed way too good to be true, but still decided to roll with it, after all, according to Aunty Mitsuki, Katsuki’s trial (which Izumi had declined to appear at for obvious reasons that the courts perfectly understood), had been an extremely quick affair, especially after an anonymous witness (Izumi had a feeling it was Nezu), leaked everything Bakugou (and by relation, Aldera) had done to not just Izumi, but also others with “Weak”, “Villainous” or “Mutant” Quirks. She knew Katsuki was bad, but it never occurred to her just how low he had gotten, and what he did to her that sealed his fate was the last thing on a laundry list of crimes that most villains would balk at. Izumi also suspected that the Pomeranian's badmouthing of the judge and his lawyer didn't help his case.

There apparently was another thing regarding the HSPC, they had made a poor attempt to defend Katsuki… Izumi learned the next day from All Might that once again, an anonymous leak to the USFJ, Japanese Military, International Union Of Heroes, the UN, and the Japanese Government, lead to a grand reorganizing and depowering of the HSPC, with it apparently coming under direct UN-Government control. Izumi had only taken a glance at what was revealed, and well, it certainly didn’t paint a pretty picture, especially considering what occurred with Lady Nagant (who was pardoned of her crimes and was apparently released into UA’s custody as an employee, or at least, that's what All Might told her), and Hawks, who had his license immediately revoked, before he testified about some knowledge regarding the Neo-MLA.

THAT whole thing was still going on, thus why her meeting with Nezu would have to go on without All Might as he, alongside other heroes and pretty much the entire Military Force of Japan, alongside USFJ and other ROFTO (Rim Of Fire Treaty Organization) allies, were preparing to finally take the MLA or whatever the current form technically counts as, down.

Thankfully, All Might promised Izumi that her proper muscle training would begin after everything that had spawned from this situation was dealt with. Izumi merely countered that the Butterfly effect was simply in full motion, which led to both laughing (cutely giggling in Izumi’s case/roaring laughter in All Might's case) about it all, despite everything.

Izumi was reminded of an old Pre-Quirk meme that went: “Boy That Escalated Quickly” which again caused the two to laugh, even Inko got involved once she was properly read into it.

Sure, Inko had a feeling that this was a bit ill-timed to be joking about it all, but reasoned that this was simply maybe just Izumi trying to cope with everything.

Anyways, back to Izumi doing her best to get out of bed as she slowly extracted herself from her All Might themed bed sheets before finally just sitting there, thinking as she caught a look of herself from the Midnight Themed mirror she had in her room.

Her eyes traveled downwards until they found nothing but an overly large and loose fitting t-shirt that said “Pajamas” in English on the front, even if said words were strained taught by her practically gravity defying bust. She remembered how her mother told her that apparently, their crying which required special industrial quality drains be installed in their apartment, and their generous assets, both Breasts and Ass, were a result of minor Mutations, not a full Quirk, but the Genetic Remnants of one, which explained why both cried enough tears to drown nine men yet didn’t get instantly dehydrated afterwards, and their larger than average assets, and for both of them it explained why A. They didn’t suffer from severe back pain B. Why both Mother and Daughter had large breasts and rears and C. Why their breasts defied gravity, never sagging, even after Inko’s pregnancy with Izumi.

Of course this meant that Izumi and her Mother had to constantly order custom made bras (and Sports Bras as well) because most lingerie stores didn’t sell bras in their size, and for Izumi at least, as she never bothered/didn’t want to ask her mother, slept without a bra due to her sensitive, and thick as a Soda Bottle Cap, Nipples, said Nipple’s currently poking out underneath the T-shirt she was wearing.

The entire reason this not safe for work train of thought even came about was due to the stigma surrounding many female heroes in regards to their often times over sexualized appearances, even if Midnight had brought about a change is legislature in regards to her first costume (which one could barely even consider lingerie and Izumi had pondered early on when she was studying Midnight how the R rated hero never once had an accidental nip slip, Izumi chalked it up that it was likely the hero used pasties before her forced change of costume), and Izumi was reluctant to trust most support companies after their so called results, especially because she had a feeling that any design she could send in would inevitably, in some way, show off her large bust or ass, not that Izumi minded that, after all, both her bust and rear were the one thing that prevented her from being entirely useless in school, even if she had to face constant abuse, teasing, and borderline sexual harassment because of it. Honestly, even if she wasn’t already an open (no thanks to Katsuki essentially megaphoning it to the entire school) Lesbian, she doubts she would have remained straight or bisexual for very long after what the boys of Aldera put her through.

Thus why she preferred to have her and her mother work on her first costume together, and All Might even promised he would get in contact with an old friend of his regarding support items if need be.

(All Might didn’t mention to Izumi that he was also going to ask David about why he hadn’t seen Melissa for a long while, and All Might knew when David was throwing poor excuses, and after what Izumi had muttered, All Might had a question floating around his head that he really didn’t want to think about too much)

Anyways, after sitting on her bed for a little longer contemplating many things, she finally stood up and began getting dressed before her Mother worried herself over why Izumi was taking so long. Getting dressed in a custom made green tank top (at this point, a vast majority of her tops were either large T-shirts or custom made) and a pair of US Army UCP surplus pants with the name tag removed (They were dirt cheap and fit). As Izumi was getting dressed, it occurred to her that she needed proper exercise clothes for All Mights training, and made a mental note to ask her mom for them to take a shopping trip for some.

Meanwhile, with a certain cat loving insomniac…

Shouta Aizawa was annoyed, confused, and tired (that last one was rather normal though) as he navigated his way through this apartment building for what was shaping up to be the problem childs of all problem childs, outside of his step-daughter, there was no topping her muttering and already bright mind (even if her Quirk had accidentally caused the entirety of Class 3-A to suddenly catch on fire or when she nearly caused Vlad to drown on dry land or when she made Mic mute for 2 days (a shame Aizawa was never able to recreate that incident ever again), honestly, her Quirk, Reality Gas, named so because the gas she secreted essentially made her a living Reality Stone from Marvel, hell, it was even red like the one from the old MCU movies, made her both extremely powerful and extremely dangerous), Aizawa, while he would never openly state so, was very proud of his step-daughter, probably because she never decided to use her Quirk on him, primarily because she was smart enough to understand he was the only one that could actively ensure she didn’t accidentally use her Quirk as she trained with it.

Sure, he, Hizashi, and Nemuri were a little apprehensive at her wanting to be a hero like them, but decided in the end to support her dream as much as possible. Considering all three were teachers at UA, and considering his Step-Daughter was essentially raised there due to her… odd origins that none of her parents could quite figure out, she was set in terms of education and overall training, especially considering Nezu took a liking to her, not only because her favorite plushy to go to sleep with was a Nezu plush (When and how Nezu had one made was forever a mystery to the UA staff), but also because both respected each others already high intelligence, something Nezu wanted to cultivate further.

Honestly, if they ever found his Step-Daughter’s other parent, Aizawa wouldn't be surprised if they were a genius if how his Step-Daughter had turned out.

Eventually, the underground hero/teacher finally found the right apartment and rang the doorbell. Honestly, he didn’t want to be the one to fetch these two, but with All Might and Mic prepping to take down the MLA, Midnight having to look after their daughter, and the other UA teachers currently still teaching their respective classes as the hero courses did their internships, he was quite literally the only option, even if he didn’t really want to, he had little other choice, especially because, whether he liked it or not, Aizawa had a feeling that the latest girl to come under UA’s technical wardship (especially after the whole Toga situation last year and then this whole series of events that caused the downfall of both the HSPC and soon, the MLA, all because of a singular girl who was nearly raped by her childhood abuser, said girl now being chosen to be All Might’s successor (that had been a meeting of a lifetime).

Honestly, the butterfly/domino effect that this girl had caused was honestly excessive in Aizawa's tired opinion.

And now Aizawa was wondering just what the hell was taking so long for them to answer the door. So he reached for the door knob and found the apartment unlocked…

To be entirely honest, maybe not sleeping for 32 hours wasn’t one of Aizawa's best ideas as it occurred to him that Inko Midoriya had called him in probably a couple of times while he was stuck inside his head thinking.

Aizawa found Inko sitting on the couch, still patiently waiting for him to enter, and the entire reason for why he was here, Izumi Midoriya, was at the dining room table writing in a notebook.

“Welcome, I presume you must be from UA?” Inko stated to which Aizawa nodded.

“Shouta Aizawa, I was instructed to bring you two for a meeting with Nezu, so for my sake and wanting to take a nap as soon as possible, we need to get going.” Aizawa stated.

Izumi looked up and her first thought was why there was a sleep deprived hobo standing at their door with a large grey scarf, before she realized who exactly it was, and her second question was mentally asking when Eraserhead had last slept properly.

“Are you ready to leave Izumi?” Her mother asked, to which Izumi nodded, grabbed her red sneakers that signified quirklessness (yeah that had been one heck of a reveal), grabbed her bag that contained her latest hero/quirk notebooks, and followed her mother and Eraserhead out of the apartment.

What followed was a brief ride over to UA, where both Inko and Izumi were given security passes, so that they wouldn’t accidentally set off UA’s security system. They were then led up to the Principal's Office and finally entered.

Admittedly, it took a bit of time to get used to seeing the indeterminate mammal that is Principal Nezu, but once they did and finally sat down, the meeting properly began.

“I must say Miss Izumi, the butterfly effect of this whole situation has been very entertaining to watch, well, aside from what Mr Katsuki put you through and that farce known as Aldera High.” Nezu began, scowling when he spoke about Katsuki and Aldera, his disdain for both evident.

At the sheer mention of Aldera, Aizawa scowled, while 1-A currently was studentless, none of them had come from Aldera, but 2-A only had three students because of the poor excuses Aldera had produced.

Izumi meanwhile, blushed slightly in embarrassment about the whole situation, making a face that Aizawa found very familiar. “Y-yeah, I’ll be honest, I wasn’t expecting this outcome either, I’m just glad Katsuki can no longer make my life a living hell, even if it took 3 years of therapy to realize just how far gone my former best friend was.”

Both Aizawa and Nezu nodded in affirmation, the former still wishing to strangle the explosive boys testicles off. Even if this incident hadn’t happened, Aizawa was fairly certain that Katsuki would’ve been one of the hundreds he would’ve been expelled on day one. Nezu on the other hand was grateful that UA never had that rotten piece of garbage ever grace its halls, even if he only lasted a day.

“Regardless, that is not why we are having this meeting, now, Izumi, I believe you have something to share with me?” Nezu turned to the green haired 18 year old with an expectant grin.

“Yes, here” Izumi quickly handed Nezu two of her latest notebooks, which Nezu quickly flipped through absorbing as much info as he could. Nezu was quite impressed with Izumi’s analytical skills, his grin widening further and further as he read on, although they seemed very familiar to him.

“Um, Nezu-Sensei, does…” Izumi made a gesture to Aizawa to which Nezu nodded.

“Yes, Aizawa has already been informed about everything All Might already told you.” Nezu answered Izumi’s unspoken question.

“And your comments on my notebooks?” Izumi asked, a bit of anxiety creeping through.

“I must say Miss Izumi, your analytical skills are second to none! If All Might hadn’t already made you his successor, I would’ve gladly taken you on as my own!” Nezu praised to which Izumi blushed once more.

Throughout all of this, Inko sat silent, like a child waiting to be called on.

“Now, Miss Midoriya, I’m sure you have questions regarding Izumi’s future training for the UA Entrance Exam… or even the Recommendation Exam if she does well enough.” Nezu asked, while also confirming that Izumi would indeed be training here, the only thing he didn’t add was that if Izumi proved herself enough, her spot in the hero course was all but secured, no matter how well she did on the exam, but that would only occur if she proved herself, which Nezu found highly likely based on what All Might had to say regarding her.

“Other than a promise that you ensure my daughter isn’t harmed, then no.” Inko declared to which both Nezu and Aizawa nodded, despite both knowing how much of a titanic task that would be.

Aizawa recognized the Mama bear look Inko had, considering he had seen the same on Nemuri regarding her daughter, speaking of…

Izumi had been muttering to herself after Nezu’s impromptu confirmation and even her own questions regarding her future training and education, something that Aizawa found extremely familiar, and Nezu grinned even harder.

Realizing what she was doing, she stopped, pinked and apologized.

“No need to be sorry Izumi, you just need to work on keeping your thoughts internalized rather than letting them leak out like that.” Nezu actually related with the mutterings, he himself often mentally rambled after he had one to many cups of tea.

“Now, as for the future plan going forward, I shall take you on as my own student in regards to anything not related to Heroics, Mr. Aizawa shall handle your combat training, I insist you go to Hound Dog for continued therapy, All Might shall handle physically training your body in order to handle One For All, and the other UA staff shall assist you if need be.” Nezu stated, before allowing the two Midoriya's to process all that.

Aizawa bit down a comment on not wanting to train Izumi, while Izumi herself had nodded in reluctant agreement in regards to therapy with Hound Dog. She wanted to argue against it, but honestly, she had no real argument against it.

“Now, I believe Miss Izumi has a physical she needs done by Recovery Girl.” Nezu said, hopping off his chair, followed quickly by the other people in the room as they made their way down to Recovery Girl’s office.

As they opened the door, Aizawa was suddenly all but tackled by a two-tone Green-Purple blur. “PAPA ‘Zawa!”

Neither Izumi nor Inko were expecting this as both sweat dropped as the now identified to be a ~10 year old girl released from Aizawa.

“Yume!” A mature sounding female voice sounded from further inside the office. Upon looking, the source of the voice was indeed the R-Rated Hero: Midnight, outside of her costume, looking fondly annoyed at the now identified “Yume”.

Said Yume was now looking down a bit in embarrassed shame that freaked the hell out of Inko, memories of a young Izumi doing the same swirling through her head as she stared at the girl’s dual tone dark purple-dark green hair. Izumi also got a good look at the young girls face and paled slightly upon what she saw.

Yume had bright green eyes, three prominent freckles arranged in a sideways triangle decorated both sides of her face, and based on the small bumps under her (Extremely rare because Aizawa forced the company that produced them to stop producing them) Eraserhead shirt, she looked quite a lot like a younger Izumi, disregarding Yume’s dual tone hair.

Nezu and Aizawa also noticed the stark similarities that Yume and Izumi both shared, and together with Izumi, the pieces quickly fell into place.

Izumi very quickly fainted out of shock, followed shortly by Inko. Yume looked confused while Aizawa tiredly looked at Nezu and asked. “You knew this was gonna happen didn’t you?”

Nezu grinned madly. “Oh no, I didn’t plan this at all, it just happened to be a circumstance.”

Aizawa suddenly had an urge to bang his head against a wall until he passed out, while Yume simply asked. “Why does the younger looking girl look like me?

For Kayama Nemuri, she merely said. “I think we found your other mother Yume… I think”

Notes:

And here's Chapter 3!

So... yeah, the butterfly effect really is strong (and Nezu is oddly protective of a girl he hasn't even met yet, or he may have just found an opportunity to finally neuter the HSPC, and the MLA was just icing on the cake)

(I also added some tags that I forgot to add)

And then we have Yume, where more info will be divulged next chapter over her... creation (and Izumi analyzing her Quirk while Yume does the same to Izumi)

Also, this chapter was supposed to include All Might, until I realized the Domino Effect that Katsuki's trial could bring (and all the chaos that comes with it... Am I just subconsciously channeling my inner Nezu at this point?).

Also in regards to Izumi's Quirk, leave your guesses in the comments, I wanna see what you all think her Quirk is (based on the context clues and one of the inspired works).

And with that (I seriously need to stop using the word "Also" to begin every new line in this), see you all next chapter.

Chapter 4: My Quirk Can Do WHAT?!

After finally waking both of the Midoriya’s, Recovery Girl decided then and there that it would be best if both Izumi and Yume did a DNA test, just to be sure.

Of course it took some wrangling (aka Aizawa and the newly hired head of security, Lady Nagant, having to peel Inko off of her newly discovered granddaughter as she practically hugged the life out of the poor ten year old girl, while Izumi was still essentially catatonic from shock), but eventually both were able to take the DNA test.

The result was rather expected, and it took everything in Izumi’s power to not faint again as the results were displayed.

97.8% Genetic Match

It was rather quiet for a good 30 seconds after that as everyone in the room (Izumi, Inko, Yume, Aizawa, Nezu, Recovery Girl, and Midnight) processed that.

It was Yume who spoke first. “So… you’re my…”

She put a finger to her chin as she thought of a word that best fit. “Mapa?”

“What?” Just about everyone else in the room stated, confused.

“Mapa?” Izumi asked.

“Yeah! You’re technically my genetic ‘Father’, but you’re a girl, so ‘Papa’ wouldn’t work, but ‘Mama’ is already taken, so Mapa! Ma as in Mama and Pa as in Papa!” The ten year old explained.

Izumi pondered that for about a second before nodding in appraisal, causing Yume to beam brightly with a smile that, to Inko and Izumi, almost perfectly mirrored Izumi’s own smile.

“Too bright…” Aizawa muttered under his breath.

“As heartwarming and artery clogging as this all is, I believe we need to figure out how the heck this even happened, Izumi if you could follow me.” Recovery Girl stated as she led Izumi into another room to conduct Quirk Tests on Izumi.

Shutting the door, Recovery Girl turned to Izumi and stated rather bluntly. “Alright, I need you to undress.”

“What?” Izumi stated, slightly confused.

“It will be easier for me to conduct Quirk Tests without clothing in the way, and because I’m Yume’s sole doctor, I wanna look into some things I noticed in regards to her development.” Recovery Girl answered back with.

It suddenly clicked in Izumi’s mind. “Oh”

“Yes, I’m referring to the fact that your ten year old daughter is already beginning to develop secondary sexual characteristics, but she has yet to have her puberty start.” Izumi quickly looked away, slightly guilty, desperately trying to hide the knowing look in her eyes.

Unfortunately, Recovery Girl caught Izumi’s knowing look. “I presume that sounds familiar?”

“Yes… truth be told, I didn’t truly start puberty until I was 13” Izumi answered, slightly uncomfortable.

Recovery Girl sighed, but didn’t push any further, understanding that Izumi was looking more uncomfortable by the minute. She motioned for Izumi to begin to undress so that the tests and medical check up could begin.

Unsurprisingly, Izumi was fairly healthy, and thankfully, she at least did have a bit of muscle mass. Not much, but she wasn’t a twig. Of course, the faded abuse scars were noticeable, but Recovery Girl noted that Izumi more or less ignored the scars, telling the elderly hero that the girl had long put that behind her.

Still didn’t mean that Recovery Girl wanted to shove her cane where the sun doesn't shine on Izumi’s abuser.

As for everything else, Recovery Girl secretly took Izumi’s measurements at Nezu’s instructions, apparently so that her uniform could be tailor made due to Izumi’s large bust and buttocks. It was when Recovery Girl inspected Izumi’s Womb via both X-Ray and Ultrasound.

She remained quiet on the matter, but it did add some info in regards to Izumi’s Quirk, along with what the Blood Tests had given her.

Meanwhile, with a blood drinking cat…

Himiko Toga wasn’t very well known as being a patient person, nor was she well known for being “Normal”, even if the definition of “Normal” constantly shifted and never seemed to ever make much sense.

Of course, for Himiko, the phrase; “Just be normal” brought up many not very pleasant memories and PTSD that put Soldiers to shame. Honestly the fact that she was still sane was a testament to Nezu’s and Hound Dog’s abilities, especially Hound Dog.

Sure, no amount of therapy would ever make that trauma vanish, Hound Dog himself said so, but compared to when Dadzawa found her, it was like night and day, and ever since she had become a ward of UA, things were actually going her way for once.

(Sure, she would’ve liked a loving family, a normal childhood, and a girlfriend, but at least she wasn’t close to insane now, and Yume adopting Himiko as her “Aunty Himi” helped tremendously)

And Nezu utterly ensured the downfall of her parents was all the more sweeter, even if both she and Dadzawa had argued for her Sperm and Egg Donors to be put in the dirt where they belonged, but they were vetoed by Momnight and Dadmic.

And now she was spending most of her time either playing with Yume, training with Dadzawa to be an Underground Hero, or doing grueling study under Nezu.

Of course, now she was marching to Recovery Girl’s office, primarily because it had been nearly two hours since Yume’s Doctor’s Visit started, and Himiko was wondering what was taking so damn long.

As she opened the door to Chiyo’s office, the last thing she was expecting to find was Yume playing with a Green Haired older Woman while Nezu, Dadzawa, and Momnight watched on.

As she slowly entered, all heads turned towards her, and Yume’s eyes sparkled even more. “Aunt Himi! Guess What! We found my Mapa!”

“Mapa?” Himiko repeated, slightly confused.

“My Daughter, Izumi Midoriya, I’m Inko Midoriya” The Green Haired lady clarified, even though that caused even more questions.

“Wait, Daughter? But… don’t you have to be a male? Unless… is your daught-”

“She’s a natural female”

“Wha-, how-, huh?” Himiko sputtered as she tried to make sense of the situation before it finally clicked in her head.

She slowly turned towards Dadzawa and simply said. “Quirk?”

“Quirk”

“Quirks are bullshit…” Himiko muttered under her breath, quiet enough so that Yume wouldn’t hear her.

“So! What's your name, young lady?” Inko asked.

“Oh! Himiko Toga… but please, just call me Himiko, I… don’t like my surname all that much.” Himiko slightly shrunk inwards.

“I understand, and I can presume you didn’t have the greatest family life?” Inko asked.

(Understatement of the fucking century) Himiko, Aizawa, and Midnight all thought simultaneously.

Himiko nodded. Having no other major questions and not wanting to go any further, Inko went back to playing with her Granddaughter.

It was while she was watching them that a question emerged in her mind. Inko looked to be only a bit older than Midnight, which meant her daughter must be young, but…

(If Yume’s Ten, then…)

“Mrs Midoriya, how old is your Daughter?” Himiko asked, not catching Nezu’s maniacal grin as she asked that question.

“First, just Miss is fine, I’m divorced, and two, 18, why?” Inko answered.

“But… Yume’s Ten, and that would mean…” Your daughter was only 8 when Yume was conceived went unsaid as the door to the private room opened, revealing what Himiko could only presume was Izumi Midoriya if the giant boobs…

*TogaHimiko.exe has stopped functioning, please wait for reboot…*

Himiko essentially blue screened as she saw Izumi massive mammaries jiggle ever so slightly in the green tank top that contained them, and Midnight noticed Himiko drooling slightly as Izumi walked up to Himiko, asking who she was.

Of course, Himiko was now in lala land as she imagined doing Not Safe for Yume things with Izumi’s chest pillows.

Since Himiko was now essentially catatonic, much to the amusement of Midnight, Izumi turned to face Inko, and Himiko’s now nuclear blush went Tsar Bomba levels of red as she saw the Army Surplus pants Izumi was wearing doing their best to contain Izumi’s fat ass.

Honestly, it was a wonder that Himiko didn’t faint or jump Izumi.

Meanwhile, Aizawa was pinching his nose as he watched Himiko drool waterfalls at Izumi’s beauty (Even he would openly admit that Izumi was a very lucky catch for anyone to get, add on her admittedly adorable personality, and it left Aizawa wondering what monsters would torment such a cinnamon roll like Izumi).

Eventually, Himiko was able to regain enough composure to introduce herself to Izumi. “H-hi… I’m Himiko Toga…”

“Izumi Midoriya, it’s nice to meet you Toga-San.” Izumi said, not noticing Himiko wincing.

“Just call me Himiko, I don’t really like using my last name much.” Himiko stated.

“My apologies… is there a reason why?” Izumi apologized before asking, after all, if anyone could understand trauma, it would be her.

“I… I don't really want to talk about it.” Himiko stated.

Aizawa decided to speak up on Himiko’s behalf. “To put it simply, Himiko’s parents all but abused her because of her Vampyric Quirk.”

(Damn it Dadzawa, now she’ll hate me…) Himiko quickly thought, beginning to think the worst, before she saw the pure fury on Izumi’s face.

(Huh?)

Inko spoke up then. “Well, I would hardly call them parents if they abuse their daughter for something she had no control over, it isn’t like she chose her Quirk.”

“Besides, it’s how you use your Quirk, not how you are, if you use for evil, you’re a villain, and if you use it for good, you’re a hero, and if you don’t use it for either, no one should really care, after all, it’s ultimately your choice on your future, and it’s not someone else’s to make.” Izumi stated, entirely unaware of the awed expression on Himiko’s face, nor the manic grin Principal Nezu was now sporting.

What she did notice however, was the ‘Thump-Thump-Thump-CLICK’ in the back of her mind that caused her to briefly look around in confusion, not catching Himiko’s confused look.

(What the heck was that?) Both Izumi and Himiko thought simultaneously.

Unfortunately, before either could figure it out, Recovery Girl walked in, carrying a few folders. “Sorry for taking a little bit, the printer decided to be overly slow today… oh, Himiko-Chan, do you require Blood?”

Himiko nodded no before stating. “No, I was just wondering what was taking so long for Yume’s Checkup, went to see and found the Midoriya’s”

She decided to just file the odd noise she had heard for later, while Recovery Girl continued. “Ah, so then I presume you’ve already been informed by Yume. Anyways, Ms Midoriya, Izumi, I have the results and theories for Izumi’s Quirk, here.”

She handed both Midoriya's folders, along with Midnight and Nezu. “Now as for the obvious, Izumi’s Quirk allows her to Impregnate other females via touch.”

“How the heck does that work?” Himiko stated, confused.

It was Izumi who looked to be thinking. “Hmmm… it’s probably a case where I need to have full finger contact with all ten fingers, and possibly the same with the other party for it to activate, but I have a feeling there’s another activation requirement…”

“You mentioned earlier that you had three separate instances of the flashes you saw, what were you thinking about prior to each one?” Nezu asked.

“Well, If I remember correctly, when I met Midnight, I was thinking about how a gaseous reality changing Quirk would function, then we hugged and I saw the flash. As for the American Girl, the primary thing on my mind at that moment was Green Lantern, and as for the Horned Woman, I think I was imagining a possible Quirk that could temporarily rewind things like the Time Infinity Stone.” It was honestly a miracle that Izumi hadn’t fully descended into a Mumblestorm.

Nezu scratched his furred chin as he processed before it clicked. “Your Quirk allows you to cultivate other Quirks through Impregnating other females with Children that will have predetermined Quirks.”

“That sounds both Amazing and utterly Terrifying…” Yume muttered.

Recovery Girl made a note of that before she continued onto the burning question, just how in the holy hell does Izumi even impregnate another female, especially at such a young age. “Now, as for the after-activation part, I noticed something bizarre in regards to Izumi’s Ovaries.”

“What, is there something wrong with them?” Inko the ever protective mama bear asked.

“Not anything wrong, just off, as in I’m fairly certain that Izumi is somehow both infertile and fertile at the same time.” Recovery answered, causing confused looks to sprout across everyone in the room.

“Wait… how?” Himiko asked, how could someone be both infertile, yet fertile, it made no sense.

“Essentially, Izumi herself cannot carry children, while she does a Uterus, the Fallopian Tubes are too thick to allow for proper Ovulation, nevermind that her Ovaries don’t function like that.” Recovery Girl answered, before Izumi figured it out.

“My Ovaries must teleport the required Eggs to the other party and through my Quirk, combine with another Egg already present, or cause Ovulation to occur.” She mused.

“Got it in one, good work.” Recovery Girl said, a small smile on her face. Having had a number of conversations with Yume, who was too smart yet simultaneously innocent, it was evident where Yume had gotten her smarts from, honestly she was more impressed that Izumi was able to properly figure it out.

Nezu smiled madly, not fully because of Izumi deducting her own Quirk out, no, Nezu was more imagining how One For All would empower Izumi’s Quirk. He was also aware that should he still somehow be alive, he should never be made aware of this, no matter what.

“Now, with that all said, Izumi, what would you like to name your Quirk?” Recovery Girl asked, despite the fact that in ten months she would have One For All and thus it didn’t really matter… aside from having to likely inform Himiko of the whole situation, because she would notice Izumi having an entirely different Quirk by the time of the exam.

Izumi idly scratched her chin in thought before she finally came up with something. “Power Cultivator, I was thinking Quirk Cultivator, but that doesn’t sound right.”

“Agreed” Himiko and Midnight started at the same time.

Recovery Girl wrote it down for posterity. “Well, with that, I believe you all have well overstayed your welcome in my office, also, Midoriya.”

Izumi turned to Recovery Girl. “Please don’t end up in this office too often, or else you can say bye to your shins!”

Izumi shuddered in fear before rapidly nodding.

And thus all filed out of UA’s Nurse’s Office.

“So, what now?” Himiko asked.

Nezu turned to Aizawa, who nodded in tired annoyance, before turning back to Izumi. “Well, now that Izumi’s visit has been concluded, I deem it wise that Izumi undergo a QAT with Aizawa and Yume.”

“Sensei? Izumi’s Quirk isn’t physical, so why would she need to take a QAT?” Himiko asked, feeling like she was missing something.

Nezu smiled. “Because I have a feeling you would rather not have to sign an NDA, I shall explain to you Izumi’s situation while we watch her QAT.”

Himiko wasn’t sure where it came from, but she suddenly felt a strong feeling of apology radiating from the back of her mind.

Izumi merely sighed, suddenly wishing that All Might was here to help explain. Then again, she was also slightly nervous as to what the QAT would entail considering what she’s read about Eraserhead, and she understood the logic behind testing on whether the Quirk’s she had accidentally created in the forms of Yume and her other two children, actually affected her or not.

Meanwhile, across the city in a nondescript building…

A six year old girl stared into the scuffed mirror of her cell, red eyes staring back as they darted across her wild Green-White hair. She knew from seeing a sole photo that her birth mama had White Hair and Red Eyes, and the story she had been told was that her curse had ended her father.

However, she had a nagging feeling in the back of her mind that something about that story didn’t add up.

She looked out the barred window into the city.

(Where are you Papa? Why did you abandon me like my Mama?)

Unfortunately, the door to her cell then opened.

“Come along Eri”

Notes:

And there is chapter 4!

Izumi's Quirk: Power Cultivator (without OFA)
- Allows Izumi to impregnate other females
- Activates by all ten fingers of both parties touching and by Izumi thinking about a possible Quirk (Other Activation possibility is by scissoring)
- When activated, Izumi will have a flash appear in her vision as the required number of Eggs from her own Ovary are transported to the Other party's Womb
- After transportation, Izumi's Egg and the Egg of the other Female shall combine and mix DNA, causing conception to occur
- If other Female is currently on a safe day, then Izumi's Quirk shall cause Ovulation to occur
- Gestation Period is shortened to only a week
- Izumi is immune to the Quirks of her Children
- All Of Izumi's Children have a 95% chance of being Female
- Izumi herself cannot carry Children
- Quirk allows for up to three to be mentally Bonded with Izumi

Power Cultivator with OFA
- Gives Izumi far more control over the creation of Quirks
- Overdrives Ovulation in the other Female leading to more children per pregnancy (Minimum of Two, Maximum of Six-Eight without Animalistic Mutations/Mina, where the Maximum is instead 12-14)
- Gestation Period shortened further to only 48 Hours
- Izumi becomes Immune to the Quirks of the Mothers
- Base Bonding ability will be combined with the One already present in OFA (Inspired by 849), thus allowing for Izumi to theoretically have 12 Bonds rather than the base 9.

Also, if you're wondering how this will affect the later story, none of the Bonded will be impregnated until much later outside of three exceptions and 1 total accident (Write your Guess's now as to who will be the outliers)

And Yes, I did make Himiko very thirsty for Izumi in this fic, primarily because this version of Izuku/Izumi is stacked, expect quite a few of the others to be affected by the IzuThirst.

And with all that, see you next chapter.

Chapter 5: UPDATE

Hello There!

Sorry to those expecting another chapter, but this must be said. This story will be placed on temporary hiatus pending a rewrite to the currently posted chapters. This rewrite is something I feel is needed, and the hiatus will allow me more time for my other stories. This story isn't cancelled, just to make that clear.

I will admit however that I was very close to outright cancelling this Fic before I reversed that decision in favor of a rewrite. The reasons why I nearly abandoned this story is rather simple: I simply just wasn't very proud of 3 of the 4 chapters, especially chapter 1, this is partially because this was the first time I've written an MHA fanfic, and hadn't gotten the same luck I had for Silver Maiden, my first ever posted FanFic for RWBY. You can tell I wanted to do better due to the story that spun itself off from this story, Connections, has a far better and longer 1st Chapter that I was actually proud of, and I'm currently working on another MHA Story spun off of Connections, but a bit more closer to Canon than Connections or Butterflies of Change has been.

If you're interested check out my other stories and the ones that inspired them.
