Chapter 1: the beginning
Izuku would admit, he wasn't the smartest kid in school, when it comes to quirks he was a genius, but relating to something like chemical structure or advanced science, he wasn't the best, but he still went through it
As Izuku walked home from school, he thought about the test he was given recently on Chemicals, he needed to study hard for that, but he also couldn't stop his training, at the moment, he was 4 months away from the UA Entrance Exam date, he was already losing sleep from adjusting the schedule, studying for this exam would be killer to his plans
However, just as he took notice of his surroundings, he realised he went the wrong way and into a empty neighbourhood, one that didn't look familiar to him
"Huh? I thought I was going the right way" Deku said to himself, however as he looked on, he saw a house that looked different from the rest, it's design was strange, having large circle windows on the top floor, the paint fading, but it was almost pure white.
Deciding it wouldn't hurt to explore a little, he went inside the abandoned house.
As he looked around, he noticed a lot of machinery laying around, perhaps this used to be an inventors home, but why would they leave all of their machines behind he wondered.
Soon Izuku found an entrance to a basement.
"Most inventors have a space to work in, perhaps the basement is where this inventor made their machines" Izuku pondered to himself, curiosity getting the better of him, he walked down the stairs to the basement, what he found down there was definitely was not what he was expecting.
He found what could be best described as a laboratory, he saw many beakers and bottles filled with chemicals he didn't know.
As he explored more, he saw an open book with ingredients, Izuku read the list and didn't know what to think.
"Sugar, Spice and everything nice?" Izuku read, as he did, he saw in the corner of his eyes what could be best described as said ingredients, a box filled with sugar, some shakers filled with different types of spices and a bucket filled with glowing flowers and, heart shapes?
Izuku, too curious to leave things now, wanted to see what would happen, plus this could help him with his chemistry exam.
Putting his bag on a stool, he got to work.
Decided to also look the part, he spotted a white lab coat and put it on, he then grabbed a pot that was left out and decided to follow the books list.
First he grabbed the box of sugar and poured it into the pot, then he grabbed the shakers of spices and shook them into the pot, then he grabbed the bucket of "Everything Nice" and poured them in, Izuku swore he could hear sounds of giggling children as he poured them in.
As he did so, he didn't notice that some loose strands of his hair fell into the pot.
He then started to stir, Izuku wanted to check again on what ingredient was next, he kept reading while stirring, not noticing the stick he was stirring with getting close to a large bottle filled with black liquid.
Izuku then looked back into the pot to see strands of his hair in it, he briefly freaked out, making him jerk the stick in the wrong direction, before he realised it, it was too late, the stick smashed the bottle, the sound of it scared Izuku as he noticed the black liquid spill into the concoction, he then saw the label of the bottle, named-
"Chemical X?" Izuku said as he quickly skimmed through the book before finding the description of said chemical, his eyes widened as he read.
"A dangerous chemical only found by Professor Utonium, one filled with much powerful potency, any contact with it can cause much unknown results" he said before he saw the pot glow, Izuku quickly backed away from the pot, but as he did, the pot suddenly exploded, throwing Izuku into the wall of the lab, knocking him out.
It was a few minutes before he finally came to, Izuku groggily woke up as he stood up, before he noticed something, somethings standing by the pot.
Standing on the desk of the pot were three little girls.
The girl on the left had blonde hair wrapped into pigtails with green swirls in them, blue eyes and a blue dress with a single black horizontal line across the stomach
The one in the center had ginger hair with green bangs and a red bow on her long hair draped over her back. The pink eyes matched her pink dress with a single black horizontal line like the blue one.
Finally the girl on the right had short black hair with a green thunderbolt shaped streak, green eyes with a matching dress with a single black horizontal line, same as the other two.
Izuku was speechless at first, till the ginger girl spoke up.
"Hello!" She said, scaring Izuku as he stepped back before calming down a bit.
"U-um, hi?" Izuku said back nervously.
"What's your name?" Asked the blonde one.
"O-oh! I-I'm Izuku, Izuku Midoriya" Izuku said before he then asked, "w-what are your names?" He asked.
"Well you made us, shouldn't you also name us?" Asked the ginger haired girl.
"M-made you? H-how did I-" Izuku stopped before he remembered what happened, the ingredients, Chemical X spilling into the pot, he also remembered seeing some of his hair in the pot.
"H-holy" Izuku Sao before quickly running to the book, reading what the concoction really was, the title was.
"Ingredients to make the Perfect Little Girl"
Izuku was stunned, he had literally just created life, before realising his hair was in that same pot, the green hair on the girls heads lead him to one conclusion.
"They have my DNA, meaning they are….my kids" Izuku realised before he fainted.
The girls looked at him before the black haired one asked.
"Is he ok?" She asked.
"You don't think Dad is sick do you?" Asked the blonde one.
Izuku then quickly woke up again, "I'm up! I'm back!" He said.
After a few minutes of thinking, he finally realised these girls were really his children, the Chemical X mixture must've been so powerful instead of one girl it made three instead.
"Th-this is incredible, I never would have thought this was possible but then again with how technology and quirks are anything can happen, but there's also the possibility that this is a first in its time so is it dangerous, what kind of side effects are there to this and mutter mutter mutter…" Izuku muttered and mumbled as the girls, his daughters looked at him.
"Wow, he talks a lot" said the black haired girl.
"Well I think it shows how smart Dad is" The ginger haired one said.
Izuku finally snapped out of it as he realised, "oh my gosh! Your names! I completely forgot" Izuku said as he looked to the girls as he pondered in naming them, "hmm, let's see" Izuku said.
He started with the ginger one, "because of your directness and opening right up to me, I'll name you, Blossom" Izuku said
The ginger girl, Blossom, smiled at the name before the blonde girl giggled.
Izuku smiles at this, "Well aren't you all cute and bubbly" Izuku said before he got an idea for her name, "That's it, your name will be Bubbles" Izuku said as Bubbles jumped in excitement
"What about me? What about me?" The black haired girl asked.
Izuku thought about it, he didn't know why, but he could feel like she was more tomboyish, he was struggling before coming up with a name, "I think your name shall be, Buttercup" Izuku said.
"Why Buttercup?" She asked.
"Well, I'm not sure, but it seemed like a tough name for a girl ya know?" He said, which made Buttercup smirk
"So do we also have your last name Dad?" Bubbles asked.
Izuku was still trying to get used to it, but she did prove a point, do they take his last name since they are his daughters.
"Well, I think so, my DNA is part of what made you" Izuku said
The girl cheered as they jumped off the desk and hugged their new dad, Izuku, while surprised, didn't feel anything wrong with this, he slowly smiled before he hugged them back
But then, Izuku realised something, his feet weren't touching the ground, he looked down to see he and the girls were flying.
"W-WHAT THE?!" Izuku yelled one shock, making the girls let go and accidentally drop him on the ground.
"Oops, sorry Dad, we didn't mean to lift you up like that" Blossom said
Izuku took time to process this before he gave a kind smile, "I-it's ok girls, it was just, surprising is all" Izuku said before he realised that the girls were floating in the air, "G-Girls! You have quirks!" Izuku said before realising something, "Wait, the chemical X!" Izuku said as he went to the book and read the description of Chemical X again, his suspicions were correct when he read it.
"Chemical X, any contact with said chemical can provide unknown results, it must've given you three quirks!" Izuku said before he remembered something, "Wait, quirks…OH MY GOSH I'M LATE!" Izuku said as he quickly grabbed his bag, the girls were confused.
Izuku quickly grabbed the book that he used to create the girls and ran out of the basement, the girls following him out, he didn't even realise he was still wearing the lab coat as he then ran out of the old house.
"I'm late for my training with All Might!" Izuku said as he ran, the girls following him with trails of light respective of each of their colors as they flew.
Later, Izuku finally made it to the beach where his training took place, he saw All Might in his skinny form who had been waiting for a while.
"There you, I was worried you were going to skip today's training" All Might said to Izuku.
"S-Sorry All Might, I got...distracted" Izuku said.
All Might then noticed the lab coat Izuku was wearing, as well as the 3 little flying girls behind him.
"You Midoriya...who are those three?" All Might asked, which made Izuku turn around and screamed in surprise.
"AH I FORGOT ABOUT THEM!" Izuku said before trying to calm down, "U-Um, All Might, y-your not gonna b-believe what I'll tell you" Izuku said
And so, Izuku told All Might everything that happened, from discovering the lab to the creation of the girls, after the explanation, All Might just looked confused.
"This is honestly the second weirdest thing I have ever heard" All Might said.
"B-but it's true!" Izuku said.
"I never said you were lying Young Midoriya, this just sounds so, unreal" All Might said before sighing as he looked to the girls, "So what are the names of your, daughters?" He asked, he was till getting used to the fact his successor was already a father at such a young age.
Blossom floated infront of the no. 1 hero, "I am Blossom Midoriya, pleasure to meet you sir" Blossom said.
Bubbles was next, "I'm Bubbles Midoriya, I like your hair Mr All Might Sir" she said sweetly.
"Names Buttercup Midoriya, toughest of the bunch" Buttercup boasted with a smirk and crossed arms.
All Might chuckled at this, "They certainly are a lively bunch aren't they?" He said.
"Y-yeah" Izuku said before he remembered, "Oh right! My training!" He said before he set his bag down and the lab coat on the beach, the girls watched him go for the trash and started training.
Bubbles looked to All Might and asked him, "Um, Mr All Might, what is dad doing?" She asked.
All Might looked to her and answered, "Well Young Bubbles, he is training for the U.A entrance exams and to get stronger, to enter a school to train heroes, you must have the body and strength for it, as well as a powerful quirk" he explained.
As the girls listened, they imagined themselves with their father in this school for heroes, since Izuku mentioned they had quirks, they could join their father, but they also had another question.
"Wait, what is Dad's quirk?" Buttercup asked.
All Might was surprised at this question, but answered none the less, "He doesn't have one, he is part of the 20% of the world with no quirk, but he has the heart of a Hero" All Might said.
"Dad doesn't have a quirk, but is training to be a hero without one?" Blossom asked.
"Not necessarily, he is training to also obtain a quirk, my quirk" he said.
While it may be dangerous to reveal his secret to children younger than Izuku, their origin was just as important as his quirk, he felt like they should know too

Later on, Izuku had returned from the beach with his daughters following behind him, as he made it to his home, he was about to knock on the door, only to remember his daughters again, he turned to them.
"O-ok girls, n-now before we go in, we need to be careful with my mom, sh-she doesn't know about you and we n-need to explain this carefully" Izuku said, he didn't want to give his mom a heart attack by bringing in 3 little girls and saying they are his daughters straight away.
"So promise me, you won't overwhelm her when you go in, understand?" Izuku said to them.
"We understand Dad" the girls said.
Izuku was slowly getting better at this, he was getting used to them calling him dad, he just hopes his Mom could get used to this too.
Izuku opened the door with his own key and walked in, his mother was in the kitchen, cooking something.
"Oh Izuku, your home a little late" Inko Modiriya, his mother said.
"U-Uh, y-yeah, sorry Mom" Izuku said, he was standing by the counter by the kitchen as the girls stood behind it next to his legs, hidden from her view.
"U-Um, Mom, I was wondering something" Izuku said.
"Hmm? What is it sweetie?" Inko asked.
"W-Well, w-what would you say if…say, I had kids?" Izuku asked.
Inko was silent for a minute before she giggled, "Oh sweetie, I would be very happy, what mother doesn't want their kids to have children of their own in the future one day?" she said.
Izuku, seeing his mom didn't exactly think about his question enough, decided to make it more clear, "Y-Yeah, w-well, what would you say if I had kids…recently?" he asked.
Inko stopped cooking for a bit and looked to her son, with some worry in her eyes, "Izuku, is something wrong?" She asked.
Izuku was sweating nervously, before he he breathed in and out before speaking, "M-Mom, I have s-some people y-you should m-meet" He said before looking down to the girls, "O-Ok girls, come on out" he said.
The 3 little girls nod before they floated up slowly, showing themselves to Inko.
Inko, was at first confused, before she noticed the girls each had some green hair in their own hair, before she made the connections in her head...and promptly fainted.
"MOM!?" Izuku yelled in surprise as he ran into the kitchen to help her up, the girls following and helping too.
Much later after Inko woke up and Izuku explained how the girls came to be, Inko had some understanding of the situation now.
"S-so you created them in an old lab you found?" She asked.
"Yep, I didn't think it would be possible but, here they are" Izuku said as the girls were floating in the air, well, 2 of them, Buttercup had already gotten the hang of the TV remote and was watching some wrestling.
"Well honestly Izuku, I thought it would be much longer than this for me to have grandchildren" Inko said, managing to joke before looking at the girls, "So, where will they sleep?" She asked.
Izuku pauses at this, he hadn't thought that much into it, should he let the girls sleep in his room? It would be kind weird, the couch? No that would be mean.
"I-I'm not sure" Izuku said.
"Hmm, perhaps they could use the guest room" Inko suggested, they did need to use that room for something.
"I guess that could work for now" Izuku said before noticing the time, "Oh boy, its late, better head to bed" he said before looking to his daughters, "Ok girls, I think its time for you to get to bed".
Buttercup groaned, "Ugh, do we have to, this is getting good!" Buttercup said as she watched the wrestling show before she looked to Izuku.
"Buttercup, if you want to have a good day tomorrow, you need to sleep" he said, with some stern but caring volume to his voice, Buttercup sighed before she turned off the TV.
"Alright" she said as Izuku took the girls to the guest room, that would become their bedroom, Inko watched and sighed with a smile.
"To think my boy is already a father, Hisashi would be so proud of you Izuku" she said.
And so as the girls were put to bed, Izuku thought of what this would entail for his future, he could only wonder, but he will live through it, he is a father now, and he wants to help his girls live in this world full of super heroes, and help him with his journey to become the next Number one hero.
