This is the first chapter of my first story. Izuku Midoriya becomes the ONE true hero with heart, unending optimism and determination. one thing about canon deku that always bothered me is that he didn't do any martial arts training to make up for his lack of quirk so I'm gonna correct that here. Not sure of the ship but most likely Izumomo or he'll just bang some select girls and OC's, there will be lemons. Not the best writer in the world so any Grammar mistakes I made let me know. This is something that's been in my head for a while and i love the concept of one punch man deku. There will be references of other anime bad guys. Enjoy.

Chapter 1 I wanna be a hero!

This is a super human society, where 80% of the population possesses some uncanny ability called a Quirk. Society fell into chaos among'st the rise of these new abilities which changed the concept of what it meant to even be human. We call those who use their quirks for the sake of peace and order heroes. My name is Izuku Midoriya, and it's always been my dream to be a hero, unfortunately for me I fall into the 20% Known as quirkless. However, I didn't let that stop me from reaching my dream. I became a hero, one that changed the world, society and the concept of the word.

This is the story of how I became the ONE true hero.

An adorable little cinnamon roll of a five year boy sits in a chair in front of a computer as he excitedly waits for his mother to play his favorite video. It was the the debut of the greatest hero in the world All Might saving dozens of injured civilians from a massive fire.

"Ha ha ha ha fear not citizens hope has arrived, because I AM HERE!"

"All Might is the coolest in the universe!" An excited izuku shouted

"I'm gonna be a hero just like All Might when I get my Quirk no matter what it is!"

"Sorry kid it's not gonna happen." Says Dr. Ujiko quite bluntly.

"Are you sure?" says Izuku's stunned mother Inko.

Ujiko goes on to explain the various tests done on Izuku as well as the Physical indicators that tell whether someone has a quirk or not. Izuku's x-rays showing that he has a double jointed pinky toe meaning he's in the 20% of today's population and that it's very unlikely that he will ever manifest a quirk.

Inko upon taking in this news can only look down at her son whose face while smiling was in complete and utter shock. She could only imagine the feelings going through him at the moment. After thanking the doctor for his time she and Izuku head home the latter of whom remained quiet as a mouse.

The midoriya residence that night

Inko was still having a hard time processing the events of today. He son was quirkless, his life would be very hard and she knew it. Her little Izuku was so happy before the doctor's visit, he had hardly said two words at dinner and just the sadness in his eyes was unbearable to her. She called her husband in America and told him, he promised that he would be home to visit in two weeks and that they will get through this as a family. Izuku while typically loving phone calls with his dad where Hisashi would tell him about various American heroes he'd seen takedown villains and Izuku would tell him about his day, but mostly talk about All Might. But today was not one of those days. Inko sees a light coming from Izuku's room and she goes in seeing her son watching his favorite video.

"He's smiling mom." said a tearful Izuku as he faced his mother.

"He's always smiling no matter how bad things get."

"Do you think… I can be a hero too?" the question carrying clear desperation.

Inko could just stand there. Taking a moment to ponder her next words, her son's entire world was crumbling. He would never have the power of a quirk, could he realistically save people with a smile and do the right thing by others as she's begun teaching him? Could he? She was his mother, and more than anything she only wants to protect him. But the world he wants to enter is very dangerous, even more so for people like him. Having gathered herself, she answers her son.

"Yes! Yes you can Izuku!" her own stream of tears falling now

"But you're quirkless so it's going to be very very very hard for you.

"If it's what you want then you have to promise me you'll work really really hard so that I wont worry about you?" Her words also carry a hint of desperation.

Izuku taking in his mothers words and turning back to the paused screen of All Might's smiling face. She believed in him, his mother believed in him. He might not ever have a cool quirk like kacchan but he was going to work harder than anyone to make up for it. He was going to be a hero just like his idol, he was going to save people and make them feel safe in the same way he did.

"Mom, I promise i'll work hard so that you don't have to worry about me!" Izuku said with new determination.

"I'll save people with a fearless smile just like All Might, and I'll always treat people good and do the right thing."

Inko wasnt expecting that last sentence but she remembered Hisashi saying almost those exact words on their last video chat.

Flashback

Izuku sits in Inkos lap as she prepares a video chat with Hisashi who should just be getting off work. Hisashi's face appears on the screen.

"Hey love, what's up mini man!"

"Hey honey."

"Hi dad!"

"So how are things going on the whole homefront?" Hisashi asked

"We're doing pretty fine over here wishing you were here though." said Inko

"You Know i'll be home before you know it love" Hisashi charmed.

"Hey dad, what kind of quirk do you think I'll have?"

"Probably a combo of me and your moms, why?"

Inko sighed " he's actually the only kid in his class who hasn't manifested a quirk yet"

Hiashi smiled "Izuku, what does a hero do?"

Izuku took no time to think about his fathers words and simply blurted " a hero saves people dad." Hisashi, happy to hear his answer, continued " that's right but why?" Izuku took a second to ponder this question but all he could come up with was " because that's what a hero does." he said almost sheepishly as if this question had a right answer.

"Izuku, a hero is someone who does the right thing because it's the right thing to do. Regardless of whatever quirk you have or what you'll gain, if you treat people kindly and always try to do the right thing you can call yourself a hero.

End flashback

Inko and Izuku remain in his room holding each other in a warm embrace unsure of what's to come but prepared to face it together.

2 years later on a playground

"Stop, you're making him cry kacchan! If you don't stop, I'll stop you myself." izuku said standing his ground despite being visibly scared.

A sinister grin slowly spreads across the face of an explosive ash blonde boy, "quirkless deku still trying to play hero." his lackeys behind him also smiling while activating their quirks, one extends his fingers while the other sprouts bat-like wings from his back floating about a meter off the ground. The blonde haired boy slams his fist into his palm causing a small explosion.

"what did he even do kacchan?" asked Izuku, wanting to avoid violence.

"He took the last melon soda at lunch so i'm gonna kick his ass for it" bakugo states with complete seriousness.

"I'm not gonna let you hurt him over something so petty! Just walk away kacchan it's not that serious"

"So now you think you're better than me!" bakugou roared

"I didn't say that, you just can't hurt people or petty reasons."

They all lung at the greenette, izuku having a hobby of studying quirks as well having been on the receiving end of kacchans explosions for years, grabs his right arm, pulls him over his shoulder and slams him! With the wind taken out of kacchan for the moment, Izuku reacts just in time to see long fingers trying to grab him. He side steps and jumps back faster than the kid expected because in the next moment he's sent flying back from a kick to the gut.

Izuku then looks up for the winged kid but he's floating about ten feet up, clearly second guessing coming down to fight izuku. The kid looks just past him and Izuku turns around to kacchan coming at him, he just barely puts his guard up to block the explosion. Izuku is sent back from the shockwave of the blast.

"You got a lot of nerve throwing me like that deku" the blonde said with venom

"If i'm gonna be a hero I can't let someone get hurt when I can help them" said izuku trying to hold on to his little confidence.

"It doesn't matter if you help because you'll never beat me you quirkless loser! Yelled the explosive boy as his hands began to spark.

They rush each other.

Aftermath

Izuku lays on the ground covered in burns and tattered clothes. He lost, but he didn't give up, he just needed to work harder. For the past two years since his quirkless diagnosis izuku had spent much time searching the internet for various self defense techniques as well as strength training exercises. With all that he's taught himself he did fine today despite his injuries, couple that with the numerous bruises and busted lip on kacchan and this was a victory in its own way, the kid he saved even thanked him and helped him up. He made his way home and when Inko saw him unsurprisingly she wasn't happy. But upon hearing he got these injuries protecting someone else from katsuki she was more proud of her little hero. She had actually been waiting for him to come home for a while now because she had a surprise for him.

"Izuku, guess what? I finally found a place where you can study martial arts"

"Yeah! I've been teaching myself but I finally get to learn from a real master! Where is it? What kind of dojo is it?"

" Slow down, first off it's called The Rising Sky Dojo and there are several martial arts disciplines you can learn there." Inko said excited for her son to begin learning.

" I was going to take you there now to meet with the masters but with you looking like this."

"NO! Now! Lets go now!" Izuku yelled more out of excitement than anger.

"Ok just throw on some clean clothes and we'll go ok. Inko relented."

After changing and a twenty minute car drive to the more wooded area of the city they arrive at a set of large wooden double doors with Rising Sky marked on a plaque at the top surrounded by large walls that seem to cover the whole block. Upon entering they took note of the very wide courtyard and in that same courtyard in front of a relatively nice classic japanese home were about a dozen people dressed in white gi's all performing the same series of punches and kicks while a tall man with black hair also wearing a white gi watched them.

While admiring the skills, Izuku continues to follow his mother as they walk to a building that actually looks like a dojo on the other side of the courtyard. Before even entering they can already hear the sounds of OSS! Entering the room they see over a dozen students, all wearing gi's, facing a brown haired woman. She had a beautiful face with wavy brown hair that went just past her shoulders and purple eyes. She wore the same color gi as the rest of her students, she was taller than Inko and you could tell she had a well defined, curvy, mature body, made evident from the bandages seen just below her exposed cleavage." alright kiddies, today was a good day from everyone and remember progress and effort is between you, and you. I'll see you all wednesday." the lady sensei dismisses her students.

Taking a closer look at the students gathering their things to leave Inko saw that most of the kids in this group were at least two years older than Izuku. After the students had gathered their things and left after asking their sensei any final questions she was finally able to speak with Inko and Izuku.

"Welcome back Mrs Midoriya, and this is Izuku I presume." She said welcoming them with a smile.

" Hello again Tabihara, and yes this is my son Izuku."

"Hello my name is Izuku Midoriya." the boy bows to the sensei in front of him.

"Hello little one, my name is Michiko Tabihara and I'm one of the two master here. I spoke with your mother earlier and she told me you want to be a hero?"

"Yeah! I love heroes and I wanna be one someday, I wanna save people with a smile just like All Might. But…he sighs, I'm quirkless. People tell me im stupid for wanting to be a hero, that you cant be one without a quirk, they call me a usless deku just for trying." His fist's clench.

"But my mom said she believed in me. I know I can do it, just give me a chance and I promise I won't let you down!" He exclaimed, just wanting a chance.

Michiko took a deep long look into this boy's eyes. " such determination" she thought. Even amongst her older students not many are able to just throw their heart out like this. The look in those emerald green eyes is all Tabihara needed to make her decision.

"Izuku, I'm gonna be straight with you, it's not very logical for someone without a quirk to want to be a hero. There are villains in this world with some truly terrifying powers, someone like you having just your brains and physical abilities to rely on will only get so far. To be the kind of hero you said you want to be will require you to face those types of villian and that in itself is akin to suicide. A quirkless hero definitely sounds impossible." she said as she closes her eyes as she bends her head with her arms crossed.

Izuku grabs his shirt and lowers his head

She then opens her eyes and smiles

"That is unless you trained here!"

Izuku opens his fighting back tears of joy, his mother smiling down at him.

" You have a look in your eyes that I like. A quirkless hero, I've already trained two pros. What's the harm in one more?"

Izuku so caught up his joy of being accepted almost missed that last line

"Wait! You've trained heroes?! His hero nerd mode fully activated.

"Yes, both the Rabbit hero: Mirko and Dragoon hero: Ryukyuu were both students of mine, and Kamui Woods was my brother's student." she stated casually.

A giddy Izuku made a mental note to add this info to his hero notebook later.

"So now that you're officially a disciple of Rising Sky it's time you settled on a material arts discipline. The masters of this dojo are my brother and myself and we have several different martial arts styles we teach, those being Karate, Taekwondo, Kung Fu, Muay Thai, judo , Japanese Jiu Jitsu, Kenjutsu and Bojutsu, and between you and me im easily the best at the last two.

Izuku had actually heard of some of these styles while he was teaching himself but now he had actual masters to teach him, he wanted to be a hero and he'd work his butt off to make it happen.

"Can I take more than one"

"Yes you can but some of these styles run after each other on certain days so you'll have to keep your mind flexible."

To the shock of the two women in the room Izuku decided on not just two when he said more than one, but practically all of them. Choosing to learn Karate, Taekwondo, Wing Chun, Muay Thai and Jiu Jitsu, this threw Inko for a loop when she considered how much these classes were going to cost but michiko assured since Izuku was so willing to learn and that the dojo does quite well and that she and her brother also run a medical clinic that does very well. Izuku can take all these classes for the price of two and Inko relaxed.

After telling the greenettes that Izuku can start learning as soon as tomorrow if he wants, and handing her a schedule listing all the styles taught on each day of the week from who teaches it, be it Michiko or her brother Keizo, the times they start to their respective age groups. Seeing how tomorrow is Tuesday, Izuku would begin learning Wing Chun.

The Midoriya's say goodbye, looking forward to seeing more of Tabihara sensei. As they exit the dojo and cross the empty courtyard they are approached by the same man who was observing the students before.

Upon a closer look they could see this man was tall, handsome with a muscular build. He had the same purple eyes as Michiko but his hair was black, ended at the shoulder with some tied in the back. He had unshaven stubble on his face and quite bushy eyebrows.

"Hello there." the man waved as he approached, flashing a warm, radiant, very welcoming smile.

The greenettes exchange hello's to the other master of the dojo

" My name is Keizo Tabihara. I figured I'd come say hi to our newest disciple." He drops to the boys level and extends a hand, " Are you looking forward to your training young man?"

" Yeah, I'm really excited to start tomorrow!" Izuku said ecstatically.

"Tomorrow huh, so you'll be learning Kung Fu from me, I'm sure my sister already mentioned it but just know that this is a tough dojo. Here we ask that you give it your all, can you do that?"

"Yes sensei! I promise to go plus ultra every single day!

"That's what I like to hear." Keizo said with a smile, "I'll see you tomorrow, young one.

The two take their leave and as they pass the large doors at the entrance Izuku turns back around to look at the sign at the top. Rising Sky.

Things had become so different since he was diagnosed as quirkless. It was nice to know that he had his mom in his corner but to know that he had a teacher who also believed in him. It just made him feel so warm inside from being accepted and acknowledged. But starting tomorrow he would take the first step of reaching his dream, he would be a hero and save people anywhere, anytime, from anyone.

"This is my start." A smile stretches across his face.

Timeskip 2 years later.

Izuku and another boy Two years his senior stand apart from each other in the middle of the dojo while others watch on from the side of the room. Both boys are wearing gloves and protective headgear, they eye each other as both assume a taekwondo stance. The older boy itches forward before going for several front kicks, izuku steps back just enough to avoid them. Stepping forward again pivoting on his right leg Izuku spins with his left foot connecting with the older boy's gut, his opponent stumbles back but he doesn't fall. Centering themselves again, this time izuku made the first move. Going for a kick to his opponents left leg which he connects, following that to a side kick to his right side that also hits but before he can recover he gets a front kick to the chest followed by a back kick that he just barely blocks that sends him to the ground.

"You ok Izuku?" asked his sensei Michiko Tabihara.

"Yeah, I'm fine sensei."

After getting back up and focusing Izuku looks for any weaknesses to exploit in his older, stronger and more experienced opponent. He decides to take a gamble and comes up with a plan, but it requires exact timing. The older boys rushes izuku with a series of front kicks with izuku dodging, blocking and countering with several of his own. Getting the distance he needed when his opponents last left kick missed, after bringing his leg back izuku connects with a roundhouse kick to his left side. His opponent stunned yet undeterred to stop the fight, he switches his footing bringing his right foot forward. This was the moment Izuku had been waiting for, the older boy as he expected was about to do a high kick, before he could even lift his leg Izuku had gone into a spin, his left foot connecting with the older boy's face. He goes down and tabihara sensei goes to check on him.

"Ryuchi, Ryuchi are you ok?" She asked concerned for her student.

The brown haired boy gets up, his head still shaking after that one but otherwise ok. Izuku even goes over extending a hand to the boy to help him up, which he accepts, at the moment ignoring the frustration that he lost to someone younger than him. The two bow, thanking each other for the spar and head back to the rest of the class.

" Ok my little piggies that'll do for today, take what you've learned from your individual spars, as well as those of your sibling students. Always remember it's important to keep your tool sharp, no matter how good you are there is always room for improvement. And as for the sparring, keep in mind " iron sharpens iron, and the same is true here."

"OSS." says the whole class.

The students of taekwondo had gathered their things and prepared to leave for the day but there was usually one who always stayed behind, going to the outdoor training area at the far end of the courtyard to practice everything he'd learned that day for nearly two hours after the others left. This is something Izuku Midoriya had done practically everyday since he became a disciple. Taking every moment he can to drill the lessons, forms, moves, and philosophies of the numerous martial arts he was learning. Not a single day went by that he didn't do any martial arts training, many of the disciplines ran back to back usually twice a week.

Monday and Wednesday were Karate for an hour and then Taekwondo. Tuesday and Thursday were all Kung Fu, Wednesday and Friday he trained in Muay thai and Jiu Jitsu. Saturday's he would come to the dojo to train alone and just use the equipment, sometimes in the training hall dubbed , The bone breaking factory, It's a building on the east side of the compound. It's full of machines, obstacles and contraptions specifically designed to train the body in the most intense ways imaginable. Sunday he would go to his personal training spot in the woods by a flowing river, there he could spend all day practicing his martial arts and meditating. Just the serenity and seclusion of this area made it really easy to focus and calm his mind.

Or he would go to the outdoor training area that was right down from the dojo where there were wooden posts, to pull up bars for various strength training exercises, sometimes his two sensei's would be sadist's and make him run insane laps through the large forested area behind the property.

Izuku was actually surprised to see how much land there was out here, the entrance and the courtyard though wide didn't show how big this place is. The main house is the large two floor traditional japanese home he first saw when he came here. That's where his masters live. Right behind that is a dormitory house for any guest and students, it has showers and twenty bedrooms, during the summer break students have the option of living at the dojo where they live, eat, breathe and sleep martial arts. Izuku had been one of those for the past two summers and it was always an unforgettable experience despite the brutal training.

The actual dojo is on the west side and it's where he does most of his training. It's a traditional looking building with a wide, flat interior with tatami mats. The names of various students who have completed their training in a discipline are on the wall. The three that stand out are Shinji Nishiya, Rumi Usagiyama and Ryuko Tatsuma. There's also an office in the back where the masters handle business.

On the east side of the property there is a large forested area that goes for miles, there's actually a river and a natural hot spring that he and some of the other students would sneak off to when they were living at the dojo in the summer.

When Izuku made it to the training area he immediately went into a karate stance and began to practice his moves. Taking everything he's learned so far on top of what he learned today and incorporating it into every strike and repeat it. Forty minutes later he switched to Taekwondo and repeated the same process. In these moments when it was just him and his effort he couldn't help but feel he gets a little stronger every time. His life has changed so much since he came here, every single day working towards his goal of being a hero. He knows full well he's nowhere near where he needs to be, but he will never stop working in the pursuit of this goal.

One year later

After three years of training a now 10 year old Izuku's skills are coming through sharply. His reflexes, technique, senses and overall power are far beyond that of a normal 10 year old, his lean, muscular body being a clear indicator for that. He was by far the strongest student of his age at the dojo. It's gotten to the point that Izuku can only spar against those 2-3 years older than him in order to benefit from fighting another person. Now that he's 10 and quite physically developed his masters decided to amp up his training. With his dedication, eagerness and willingness to learn and constantly get better and stronger not for his sake but to be the hero he wants to be, it's no surprised he became their #1 disciple. Michiko had decided to teach him some long forgotten techniques to increase your speed, apparently with enough training you can move at supersonic speeds just by kicking yourself hard enough off the ground and it was a technique she learned from a ninja when she was young.

Keizo was more focused on improving his overall agility and dexterity. From doing acrobatics akin to monkey style kung fu to many hours of training on the wing chun spinning dummies in the bone breaking hall. The pain and soreness of everyday was something he'd gotten used to but with this new training it's taking some time to adjust but he was happy nonetheless.

"Izuku." his mother asked

"Yes mom."

"How have things been at school?"

"Fine, I got another A on my test today, I'm actually at the top of my class according to my teacher.

"Well that's actually what I wanted to talk to you about. How would you feel about taking advanced courses?"

"I'm not against it but it depends on what the classes are, I'm perfectly fine staying on the normal track but if the classes aren't beneficial to me being a hero I'm not interested.

"By the way I wanted to start a new morning routine before school. Nothing too intense, just something to wake me up quicker and get me ready for school."

"Don't you think you're maybe overdoing it a little? I support you fully but don't you think you're pushing your body too hard, you did say the masters stepped up your training." Inko asked, slightly concerned.

"It's a warm up compared to what the masters have me do. He said holding back a laugh, It's only 100 push ups, sit ups, squats and a 10 kilometer run. I'll add more to it over time but this is just a warm up.

"Just don't push it too hard ok."

"I won't mom." He says with a smile.

That's chapter 1. Everything here was to lay the ground work for who Izuku will become later. what kind of fighter he'll be, what he can do, how he trained. Next time Izuku's limiter will slowly start to break and he will have several battles of convictions, the quirkless vs the quirkful, the weak vs the strong.
