Time to answer your question!
Chapter 1:
Guest 1: I just read your deviant art well let just say great job there many stories in MHA about our green hero mix with oc or some random student but I prefer Kaminari a child with a qurik that can fly like a fairy and make some electricity from wing that can shock villain bad and some gentle electricity for healing I think to much about the child because I think on the future oopsi.
-Oh dear, I can say to 100% that Denki would be not paired with Hiro. It's a self-insert which means: Self-insertion is a literary device in which the author writes themselves into the story under the guise of, or from the perspective of, a fictional character. The character, overtly or otherwise, behaves like, has the personality of, and may even be described as physically resembling the author of the work. And Denki is so not on my radar. My babes are Izuku, Shoto, Momo, Tsu and Ochaco. We will see the most flirts with them before the pairing is decided or I say fuck it, let's make a harem :D Thank you for your comment and please continue supporting me by reading and commenting!
Have a nice day/night!
Now on with the story!
Chapter 1: Umemoto Hiromi: Origins
"Come on Hiro, we are going to be late!"
"Tenya, we are an hour here earlier than we should be, we can never be late!"
"As the best students of the Somei Private Academy, we must be earlier here for the U.A. Entrance Exam. We would bring shame to our school if we didn't."
"Of course."
"Also we want to both enter U.A. This will show the principal and teachers what trustworthy and punctual heroes-to-be we are!"
"Whatever makes you sleep at night."
Seeming satisfied with her answer Iida Tenya marched on to U.A. High School, while Umemoto Hiromi just deadpanned behind his back.
Tenya was her best friend since kindergarten, but he was sometimes too much with his obedience to rules and his perfectionism.
She liked rules too and followed them, but sometimes you had to rebel a bit.
Not all rules were good, as too much freedom wasn't good either.
It needed a good balance.
Being the only daughter of two Pro-Heroes Hiromi or Hiro, for her friends and family, had often with them philosophic discussions over good, evil and the grey zone.
Her parents tried to raise her free and to be a good person, however, she still had a curfew and other rules to follow.
Like any teenager, she, besides Tenya apparently, fought some rules and rebelled.
Alright, it was a soft rebellion.
Mama and Papa were open with her about why this rule was important, so she didn't feel the need to break it.
Hiro only sometimes stayed out later than her curfew.
For example: maybe the movie she wanted to watch ended after curfew, so yeah then she broke the rule.
It is not like her parents caught her often, being busy with their big Hero Agency and their 50 sidekicks.
If she didn't have Tenya and his family, Hiro would be often alone.
She was thankful to have the Iida's in her life.
Still, did they need to be this earlier at the Entrance Exam?
As Hiro guessed the doors were still closed and they had to wait.
Tenya and her were the first teenagers to arrive.
Typical.
Her best friend wasted no time and re-read a book about being a good Hero, while she saved some pins on Pinterest about her favourite fictional boys and girls.
She liked to read too, but she didn't think to bring a book along while they waited, so... thirsty over drawings was it.
It was also the only action she ever got, thanks to Tenya the cockblock.
Tenya saw her as his little sister and had this crazy idea to protect her virginity or some similar shit when Hiro just wanted to date someone.
Girl, boy, neither, all, she didn't care!
Yes, she wanted to be a Pro-Hero, but she wanted to experience love too.
Maybe she would find a nice partner here in the U.A.?
But for this, she needed to ace the entrance exam.
Yeah, only one of these two things could happen.
Hiro wasn't that lucky.
Her Quirk was Fairy, not Leprauche.
Not that she needed a pot of gold, however, some Irish luck would be nice.
After one hour they finally could enter the school.
Since they were from the same school, they sat beside each other.
The auditorium filled slowly and a teacher handed out printouts.
On the printout was the information what they would expect to face today.
A writing exam and a mock battle scenario.
Her butterfly wings flutter a bit in excitement.
She couldn't wait to show all how hardcore a fairy was.
Not some cutesy little things!
As the last examines arrived the Pro-Hero Present Mic came to the stage and greeted them.
"For all you examinee listeners tuning in, welcome to my show today! Everybody says "Hey"!"
Present Mic waits for a response but gets none.
"What a refined response. Then I'll quickly present to you the rundown on the practical exam! Are you ready?! Yeah!"
Again silence.
Hiro even yawned.
That's when she heard a voice mumbling: "It's the Voice Hero, Present Mic! Wow! I listen to him every week on the radio. I'm so moved! All the teachers at U.A. are pro-heroes!"
Curious about who was talking so loudly to himself Hiro turned around and saw the most adorable boy she had ever seen in her life!
He had spiky green hair, soft green eyes and adorable freckles on his face.
Hiro's heart beat faster.
He was so cute and how he was so excited made him even more adorable.
She wanted to kiss his freckles!
"Hiro!", whispered Tenya. "It's not nice to stare, turn around."
Oh, ups!
Thankful, beside Tenya, no one saw her drolling for Green Cutie.
The girl returned her attention to Present Mic, who explained the mock battle scenario.
It was simple, they would be brought to a fake city district and robots would hunt them down.
With the help of their Quirks, they needed to destroy them and earn points like this.
Any robot has a different value, so be careful when choosing your opponent.
More points meant the robot was also more dangerous.
That's when Tenya raised his arm.
"May I ask a question?"
"Okay!", said Present Mic.
Tenya holds up the printout of the robots and points at a fourth one they hadn't discussed.
"On the printout, there are four types of villains! If that is a misprint, then the U.A., the most prominent school in Japan, should be ashamed of that foolish mistake! We examinees are here in this place because we wish to be moulded into exemplary heroes!"
"Tenya, I'm sure there is a logical explanation for this.", she whisper-shouted to her best friend.
Dear Amaterasu, only him!
However, Tenya didn't hear her and even turned to Green Cutie.
"In addition, you over there with the curly hair!"
"Huh?"
"You've been muttering this whole time. It's distracting! If you're here on a pleasure trip, then you should leave immediately!"
"I'm sorry…"
Nearly everybody started to laugh.
Annoyed Hiro gave Tenya a little slap, he looked at her betrayed, before she turned to Green Cutie and whisper-shouted to him: "Please excuse my best friend. He is practically married to rules and regulations and that makes him a huge pain in the butt sometimes."
Green Cutie blushed so red that he looked like a strawberry now and stuttered something like that it was alright.
Hiro gave him a cute smile, which made him even redder before she turned back to Present Mic.
The Pro-Hero explained how the fourth robot was the biggest and most dangerous, but he gave zero points.
He was there to make their lives difficult.
Nothing more.
Tenya thanked him for the explanation and set back down.
Then with the words Plus-Ultra, and Go Beyond they were dismissed.
Hiro warmed herself well up with stretching as she waited for the mock battle exam to begin.
Sadly Tenya was in another battle zone, they probably didn't want friends and classmates to help each other, so she had to get alone ready.
She warmed up her wings by fluttering with them fast, but not flying.
The red-haired girl heard how some people talked about her and pointed.
"Hey, do you see the little fairy?"
"The red-haired one?"
"Is there another fairy? That's the daughter of Lady Butterfly and Lightshow!"
"What? A daughter of two Pro-Hero? That's unfair!"
"I don't know dude, she is so tiny and cute, can she even fight?"
Laughter.
"Well, one last rival to worry about."
Hiro stopped her stretching and sent this idiot's killer intent that they started to shake.
"What did you say about me?!", she said calmly, cold as ice.
"Nothing, nothing! We are sorry.", they cried like babies.
She stopped her killing intent and gave them a sweet smile.
"Good, I thought I heard something bad about me."
"No, no!"
"Okay, start!", sounded the voice of Present Mic over the speaker around the area.
All were just confused for a second before a guy with blond spiky hair ran into the mock city and an explosion where to be heard.
Oh!
The Exam has started.
Hiro either didn't waste time and flew into the city.
A robot was waiting for her, however, she shot a light beam from her hands and melted it so.
"Okay, one point. I need more!", she mumbled to herself.
So she started to hunt for robots.
Sometimes she saved the other examinees if they were in trouble, she wasn't an asshole and her parents always said a hero has to help people.
Then when the 10 minutes were nearly up the giant robot turned up.
Hiro wanted to show off.
She wanted to bring him down, but sadly the spiky-haired blond guy with the explosive hands was faster than her and destroyed the thing.
Blinking Hiro flatter in the air.
"I wanted to do this!", she whined.
So much for showing off!
One week later, Hiro found the accepted letter from the U.A. in her mail.
Her parents were at work, so alone she watched on the Hologram how All Might congratulated her on passing the writing exam and how she made fifth place in the battle exam.
The U.A. didn't only count the villain's points, for destroying the robots, but also rescue points, for helping others.
The Hologram turned itself off and Hiro just stared at the TV.
Well, she had made it.
She would go in April to the U.A.
She even managed to make the fifth place.
This was good.
The middle was good.
Just...it would be nice to celebrate with someone...
Maybe her mama or papa were in their office.
Hopeful she called, yet only their secretary picked up.
Like the obedient daughter she was, she told the secretary she had just good news for her parents, but she would wait for them till they returned home.
Signing she rolled herself into a ball and could feel the tears in her eyes.
Was she sure about becoming a Pro-Hero?
Hiro wanted one day a family too.
A husband or wife or partner and at least three kids.
A cute little house with a garden and a cat.
Maybe even a dog.
But, when she was a Pro-Hero she would be like her parents, barely there for her children.
She didn't want them to feel like she felt right now.
Ha! If someone would want to start a family with you, you little freak!
Hiro shook her head to banish this evil voice in her, as her phone sounded with a message.
It was Tenya.
Tenya-Bro: I got in! I got in! And I saw you made fifth place congratulations Hiro!
A smile formed on Hiro's lips.
Count on Tenya to lift her spirits.
She wrote him back.
April came faster than she thought and Hiro was on the way to the U.A.
She wore her new school uniform with black tights and with pride.
Her parents had celebrated big with her for entering the school and making even fifth place.
Papa was also a student from the U.A. once and only had made tenth place.
They were so proud of her!
It had been an amazing day.
A whole day with her parents and doing whatever she liked.
But now she was back in reality.
Her parents are at work and she of to school.
U.A. was beautiful as it was huge.
Hiro know her classroom was 1A, the same as Tenya.
Seemed that both would go forever in the same class.
As she entered the room she saw her best friend squabbling with the spiky-haired blond who took the big robot from her.
"Hey Tenya, what's wrong?", she asked and walked up to them.
The blond gave her a once over and seemed to dismiss her.
Okay, she already hated him, while Tenya explained how he tried to tell their classmate it was not right to put his feet on the table.
Before Hiro could answer the door opened.
"It's him…", said Tenya.
Like the rest of the students, Hiro turned to the newly arrived.
Oh!
It was Green Cutie!
He made it too!
Hiro was happy for him.
Also, he looked adorable in the school uniform.
Meanwhile, her best friend stepped towards Green Cutie and declared: "Good morning! My name is Iida Tenya from the -"
"Yeah, I-I know!", interrupted Green Cutie stuttering.
Gosh, he was really so adorable.
"Uhh… I'm Midoriya Izuku. It's super nice to meet you…"
And he had even a cute name.
Hiro stepped to them, as Tenya said something about Midoriya finding out the true reason for the entrance exam.
Midoriya seemed just lost for words.
"Hi, I'm happy to see you again.", greeted Hiro with the best smile on her red lips.
Izuku blushed up a storm and hid behind his arms as he met again the pretty fairy princess who was nice to him during the entrance exam.
She looks so good in her school uniform...
Not knowing Midoriya's thoughts Hiro gave him her name: "I'm Umemoto Hiromi, but call me Hiro. All do it."
Now everyone was whispering after hearing her name.
"Umemoto? Like Umemoto Hikaru or Lightshow the Prohero?"
"And his wife Umemoto Chou alias Lady Butterfly! I love her!"
"Wow, two Pro-Hero parents, how cool!"
Hiro just deapannend.
Always the same.
Tenya patted her head.
He knows her.
Izuku wondered why pretty Hiro with the beautiful wings, shining red hair and blue eyes like the sky seemed so annoyed now.
That's when a girl's voice shouted: "Hey, I recognize that messed up hair! Falling boy!"
It was the other pretty girl he had met on the entrance exam.
Both girls he found attractive in one class wouldn't be good for his nerves.
"Not that I'm surprised - that punch was amazing! Take that!", exclaimed Ochaco, not knowing either what Midoriya thought.
Hiro got curious.
"What punch, if you don't mind me asking?"
The brunette girl faced her...and Hiro's brain short-circuited.
Oh no!
She was beautiful!
That's the second attractive person for her in one class!
Was this heaven or hell?!
"Oh the boy is super strong, he demolished one of the big robots with just a punch!", explained Ochaco and had to hide a blush.
The red-haired girl reminded her a bit of Bloom from Winx Club, her first fictional crush.
And now a real-life fairy was before her.
This was so amazing!
But she needed to be cool, so Ochaco blurted happily: "What do you think we're doing today besides orientation? I wonder what our teachers are like! I can't wait to meet everybody!"
Hiro couldn't answer the brunette beauty since a hobo in a sleeping bag called them out.
The hobo turned out to be their teacher Aizawa Shota, who told them to change into their gym clothes and meet him at one of the sports fields.
Confused the teenagers did as they were told.
In the locker room, Hiro meets the other girls in her class.
One was invisible and really energetic.
One had short black hair and seemed to be a rocker.
One looked like a cute alien and was super social.
Then there was a beautiful girl, her black hair in a ponytail and her boobs.
Wow!
Hiro's head slammed formally into the gutter.
Just a tiny squeeze...
No bad hormones!
She gave her libido with an imaginary frying pan a hit.
Then there was Cutie Brunette and a girl who was frog-like, but still super cute!
There were only seven girls?
Talk about gender discrimination.
Anyway, the girls made their way over to the sports field and met up with the boys.
One boy in particular caught Hiro's eyes.
But not in a good way.
He was tiny, had lilac balls as hair and formally drooled over all the girls.
That was a perv, Hiro was sure.
She felt it in her gut.
Aizawa-Sensei stepped to them and told them they would do a Quirk assessment test.
The class repeated it confused and Cutie Brunette even added they would miss orientantion.
Their sensei didn't care and told them life was unfair and he could decide how he taught his class.
He called for a Bakugo, who was the angry blond spikes dude who stole Hiro's robot kill and told him to throw a softball with his quirk.
Bakugo got ready, he even screamed die and the ball flew 705.2 meters.
Now nearly everyone got excited to test out their Quirk, but Aizawa-Sensei stifled this joy by telling them who would be last in the class would be expelled from school.
Oh no!
I have to give my all! You can do it, Hiro!
The first test of eight was a 50-meter dash.
Okay, Hiro could handle it!
She batted her wings as fast as she could and made 4,55 seconds of time.
Not bad.
The second test was Grip Strength. Hiro only managed 50 kilos.
Uurgh, she needed more muscles!
Standing long Jump, the third test, was no problem for her since she gave herself a boost with her wings.
In Repeated Side Steps, she can only help a bit with her wings to be faster, but it is also okay.
The fifth test was a ball throw.
Brunette Cutie managed to hit infinity and Hiro wanted to marry her.
This was such a turn-on!
When it was Hiro's turn she used her light beams to make the ball fly faster.
She got a good 703.3 meter.
When it was Midoriya's turn all turned into a drama.
Apparently, Midoriya's Quirk demolished always his bones and Aizawa-Sensei wasn't having it.
With his own Quirk, he erased Midoriya's Quirk, outing himself as the eraser hero Eraser-Head.
Aizawa-Sensei gave him one last chance and somehow Midoriya managed to only break his finger.
He was still standing and now Hiro wanted to marry him.
He was so cool
But it could be a problem since Bakugo wanted to kill him and called him Deku.
Anway Aizawa-Sensei prevented Midoriya from homicide and they continued on with the tests.
After they did the rest of the fitness tests it was time for the moment of true.
Who would get expelled?
Hiro hoped for the little perv since Bakugo was way too good with his Quirk to get expelled.
Since Aizawa-Sensei had no interest in explaining to them how the point system worked, so he would show them the classification.
He pressed a button on his smartphone and a hologram appeared.
The classification was like this:
Momo Yaoyorozu
Shoto Todoroki
Katsuki Bakugo
Hiromi Umemoto
Tenya Ida
Fumikage Tokoyami
Mezo Shoji
Mashirao Ojiro
Eijiro Kirishima
Mina Ashido
Ochaco Uraraka
Koji Koda
Tsuyu Asui
Yuga Aoyama
Hanta Sero
Denki Kaminari
Kyoka Jiro
Toru Hagakure
Minoru Mineta
Izuku Midoriya
Oh, she was fourth, this made Hiro happy, but no, poor Midoriya.
He didn't deserve to be expelled.
"By the way, I was lying about the expulsion.", told them Aizawa-Sensei dry.
All the teenagers just stared in disbelief at him.
What the hell?!
Why did he trick them?!
"It was a rational deception to draw out the upper limits of your Quirks."
"WHAT?!", shouted Tenya together with Midoriya and Brunette Cutie.
Hiro just made a facepalm in disbelief.
How could she fall for such a trick?!
"Of course, that was a lie.", agreed Momo with their teacher. "It should have been obvious if you just thought it through."
Besides Momo no one had thought of it, they all had feared for their future.
Aizawa-Sensei declared the hour for over.
He advised them to go to their classroom to pick up handouts with the curriculum.
Then he handed Midoriya a note, so he could visit Recory Girl to get healed.
With this class, 1A left the sports field.
"I'm proud of you Tenya.", told him Hiro as they made their way out of the school. "That you want to be friends with Midori after you were so mean to him."
"It's Midoriya, Hiro."
"Midoriya, right! Look he is there."
They both called for Midoriya.
He stopped curious.
"Is your finger healed?", asked the taller boy.
"Yeah, thanks to Recovery Girl.", answered Izuku.
The three started walking together.
"I was really taken in by Mr. Aizawa. I even thought, "This is the best of the best" and such.", told them Tenya. "I didn't think a teacher would encourage us with a lie."
"I was disappointed in myself that I didn't catch the lie.", lamented Hiro.
Again they heard someone calling for them.
This time it was Brunette Cutie.
"Hey! Guys! Going to the station? Wait for me!"
So they stopped.
Smiling the girl came to a stop before them.
"You're the infinity girl.", said Tenya.
"I'm Uraraka Ochako. Um, you're Iida Tenya, she is Umemoto Hiromi and you're Midoriya Deku, right?"
Surprised Midoriya shouted Deku? How did she think it was his name?
Her explanation was how Bakugo had called him Deku.
Shy Midorya explained how Kacchan aka. Bakugo used this name to mock him.
"An insult?", repeated Tenya and Hiro together, while Midoriya nodded.
"Oh, is that right? Sorry! But "Deku" sounds like the Japanese word for "You can do it!" so I kinda like it.", told them Uraraka.
Midoriya turned so red that he formally steamed and declared: "I'm Deku!"
This surprised anyone.
Wasn't Deku an insult?!
Why the sudden change?!
Midoriya mumbled something about a Copernican Revolution.
Uraraka was confused, while Hiro only remembered the Copernican Revolution from school, which meant the paradigm shift from the Ptolemaic model of the heavens, which described the cosmos as having Earth stationary at the center of the universe, to the heliocentric model with the Sun at the center of the Solar System.
So Midoriya turned Deku into another meaning?
Hiro was confused too.
Whatever, in the end, the four teens walked together to the tram and learned about each other.
In her heart, Hiro felt that she had made two super cute new friends and had still her best friend on her side.
She couldn't be happier.
