Chapter 1: The worst thing to have on your exam is a stomachache.

Midoriya Izuku's POV

People… are not born equal.

For the past 11 years, ever since I was 4, I have been reminded of that fact. A reminder that I was not blessed with the gift of a quirk. That I was looked down by everyone else because of it. That my dream of becoming a hero , one who would who save lives with a smile just like him, was a fruitless endeavor, a pipe dream. Even so, I strove hard for that dream, not letting the fact that I was quirkless hinder me.

I chased onward, obtaining physical strength through rigorous workouts, learning combat techniques through Judo and Boxing and using my passion for heroes to hone this analytical thinking in the hopes that I could become a hero one day even without a quirk.

Even so, why?

10 months ago, on a fateful April Wednesday, I met him, the one hero I had the utmost admiration, the no.1 hero, All Might. I asked him the same question, the question that I beat my soul with in doubt sometime.

"Can I be a hero even without a quirk?"

In the end of it all, he told me. "You can be a hero." and from that day on, my story began or so I thought.

For those 10 months, I trained even harder, all so to inherit his power, this time not just to become a hero but to be a great hero , to be just like him, to go beyond the limit, beyond plus ultra.

Then why?

And this morning, after 10 months of hard work, after clearing Dagoba Beach Park clean of trash, I inherited this power, One For All, the quirk that has stockpiled power and passed down through 8 people, the quirk that made All Might a symbol of peace.I thought this was my starting line to my road to becoming a hero.

So why? Why? Why? Why? WHY? WHY WON'T MY BODY MOVE?

Third Person POV

Midoriya Izuku laid there on the ground, the mini-city landscape that was once UA's entrance exam had changed after the alarm rang. It was the 2nd Phase. The giant robots that were called Arena Trap had been awakened, wreaking havoc, no one would fight them after all, they were worth 0 points.

He laid there not because he was beaten by them, not because of fear. He laid there because his body started hurting as soon as the exam started. His body was shaking, a fever was coursing through him, a heat that even Endeavour knew was unbearable, a heat that can be seen by everyone.

Izuku was vomiting again, there is blood in it. "Was his body rejecting One for All?" was the fear that was inside Toshinori Yagi's head as he looked through the screen of his successor suffering from the Monitor room where all the staff were. He should go down and stop the test and save him. Any of the teachers should have gone there to save him, but this never happened before and they could stand in shock from what they are seeing.

Izuku clawed at the dirt beneath him. He yelled in frustration at the sky. The heat from his body had started to melt his surroundings. The earth beneath had already cracked from the pressure he was exerting and yet his body would not move to his will, His stomach was churning like there was a vortex inside him. He could hear his heart beating clearly as everything around him was silent except for the sound of the Arena trap marching towards him. They were still far away but yet he could hear it all clearly. He could see them clearly too, two of the Arena Traps walking forward in a line.

His tracksuit had been ripped apart from the wind pressure, leaving him in only his track pants that had turned into shorts .Cuts and wounds started appearing him on his body, cuts and wounds that he never had appearing as if they were familiar to him, his body was numb from pain but those wounds felt like he had them for a while. His body continued to shake as he tried standing again but all he had managed was to be kneeling on one knee.

The wounds had vanished from his body as if they were never there, his vision became blurry for a moment as he could see normally again. "Wait, isn't that …?" In front of him a couple meters away, a girl was buried among rubble from the destroyed buildings around them, everyone else had already left chasing after the worthwhile villain bots that had points.

"She is…."

"Sorry for using my quirk on you, its a bad omen to trip and fall especially on a day like this. Anyway, good luck to the both of us in the exam. Bye."

The Arena Traps were already behind her, they would not be able to see her underneath all the rubble, they would crush her indiscriminately. Even though his body was still in pain, Izuku's body moved by itself.

Few minutes earlier...

Uraraka Ochako's POV

"Release-" With my fingers closed together in a diamond shape, I exhaled as the rubble floating above crashed down onto another villain makes it 28 points now. Let's keep pushing this moment-

"AHHHHHHHHHHHHHHHHHHHHHHHHHHHHH"

I could hear a scream nearby, fearing that someone was injured , I ran towards the source. It was the boy in the morning. He was lying on the ground in pain, I have to go help I rushed towards him, a gale of hot wind pushed me back as i crashed into a wall, knocking the wind out of me.

"30 minutes have passed. Initiating Phase 2-" The announcement from Present Mic came and with it, sounds of rumbling coming from below and before I knew it.

"Huh?"

And in an instant, the walls fell and I was buried underneath rubble but even then, as I blacked out, all i could think and see is the boy through the small gap, being in pain as he screamed, I wished i could help him.

Midoriya Izuku's POV

In that instant, my legs stopped being jelly. I could still smell and taste the aftertaste of vomit in my mouth. The fever was still going on, there was a migraine bursting through my brain but a single thought came into my head. Save her.

I remembered a video I saw of All Might once, a man jumped from the 20th floor of a burning building, trying to escape from the fire. With a single leap, All Might jumped and carried him away to safety in his arms. To leap that high to save someone, that was what i wished at that time and my feet began to move, it was a step and then a walk and without thinking, my feet was off the ground, 7th story high. Everything was by instinct but i remembered clearly, every sensation that my body went through and then another thought came to my head, one of activating my quirk.

"Clench up your butt and let your heart cry out"

My right arm pulled back, it felt like time slowed down , I could see the entire exam area clearly, I could hear it all clearly. I could feel the adrenaline coursing through my body, the veins on my arm started glowing and pulsing, it turned into a bluish green lightning covering my body." So this is One for All." All the fear that the quirk was rejecting me or that I was unfit faded and with it came relief and righteous indignation.

[ SMASH!]
With all my might, I punched the main body of the robot at its center. For a single moment, nothing happened as if the world could not catch up with the force I had just dealt and then the Arena Trap was blasted back , crashing into the other Arena Trap as the wind pressure and impact drags them back like a horizontal tornado, that section's surviving villain bots were destroyed from the sheer force of wind as everything was blown away and I soon blacked out in the air not before feeling someone grab onto my arm.

Third Person POV

At Sector 3, it was a disaster. The exam was prematurely stopped a few minutes before its allotted deadline and the students were ushered into the waiting room by the other teachers.

"We almost had blood on our hands from our would be something this school would be able to recover from. It was only good fortune that the boy was able to rescue her in a pinch." The principal was on the right shoulder of All Might, surveying the destruction caused by Midoriya's power in the exam all might's arm, the boy was blacked out.

"I have failed Young Midoriya, to have not foreseen the transference of power would have been like that. Even when he was screaming in pain, we all could only stood there."

"Examinee Uraraka Ochako has been moved to Recovery Girl's Office. Beep." said the rescue dispatch robot as they passed by the two teachers before continuing their work.

"Even so, a child's quirk awakening should always relate to their quirk but the power that came out of him and his sudden control of it, that is no normal awakening. He had more than just a taste of his power for the first time, All Might"

"Principal, you have an idea on what is going on with this child's quirk?" They had reached Recovery Girl's office, placing the sleeping child on a empty bed beside Uraraka Ochako. The two student were the only unconscious students from the exam.

"There is a theory by scientists studying quirks, as we pass through each generation, the Quirk Factor in every new generation becomes stronger which would eventually lead to a generation where the quirk factor goes beyond, some say it would lead to another human evolution surpassing the existence of Quirks, some theorized it would lead to the end of humanity but the main defining fact is that all quirks are in nature stockpiling power by passing through every generation like One for All. There is also another eccentric scientist, one who participated in my creation, Professor Aozuki Inukai, later on in life before he passed away,, he published a study on quirklessness. He was able to conclude that quirkless still had a quirk factor which allows them to pass on their parent's genetic pool of quirks but due to a form of genetic mutation between, the individual would have no quirk itself. Or to put it in better terms, as each generation passes on their quirks, the cup which represents their quirk factor becomes bigger but their quirk represents the liquid that is filled in the cup and in midoriya's case, his cup is empty. Professor Inukai also had an interesting theory, which is a quirkless individual may have a stronger quirk factor than its peers due to a lack of quirk. Of course, this theory was not proven due to being unable to measure one's quirk factor without a quirk but ever since meeting you and comparing it to Shimura Nana, that theory might be true. Putting the theory of Quirk Singularity and Inukai's research together, we can come to a conclusion." Finishing his reasoning, Principal Nezu plopped down on a seat and poured himself a cup of tea.

"Then, you don't mean…Midoriya, the quirk I gave to him…."

"I believe we just witnessed the first ever Quirk Singularity Evolution." Unbeknownst to them, a girl had heard them after waking up.

"Excuse me, I am sorry I overheard what you two said. I won't say a word to anyone else about it" Uraraka Ochako bowed before staring at Midoriya.

"I am glad that you are awake ,Young Uraraka. It can't be helped, we did speak knowing you were in here but yes , please keep it a secret.I beg of you. I would also like to apologize on behalf of everyone else, we hesitated when you were buried underneath the rubble." All Might bowed back, cursing himself for not being aware that they spoke in the presence of someone else even if she was asleep awhile ago.

"It's all right… so Midoriya-san was the one who saved me? And he inherited your power?"

"I guess we at least owe her an explanation in exchange for her secrecy, don't you think so, All Might?" He agreed and they both told her about One for All , the injury that lead him to needing to find a successor and the day he met Midoriya Izuku. She left soon after, her injuries healed.

Midoriya Izuku dreamed of fire, in the dark fog within his dream he saw a man hidden behind the fire. "Now is not the time but remember, you are not alone." It was his own voice coming from behind. As he turned around, Midoriya Izuku was faced with a copy of him.

"Who are you?"

"I am a part of you, the part that has been sleeping within you for the past 11 years. It has come time to accept me. You will succeed us and stop him once and for all." The copy held his hand and for a moment, he saw 8 individuals, one of them looked like his mentor. The flaming hand of the duplicate touched his hand and the last thing he saw was a blinding cyan light.

Midoriya Izuku woke up with a jerk in an unfamiliar room with a white ceiling. The pain in his body long since subsided but his body was sore especially his limbs. Tears started to come out as he realized he probably failed the entrance exam and he was not able to control One for All. As his arms started to shake, he felt someone hugging me.

"Young Midoriya, you are awake. I am glad. I am so sorry that you experienced that, I did not think One For All would affect you like that. It never happened before. I was so afraid that something bad would happen to you so much."

"All Might…" Izuku hesitated to say it. "I failed, didnt I? I did not defeat any of the villain bot with points and most of all, I lost control. I failed you."

"On the contrary, you did not." A mouse popped above All Might's head. "That's right. The one who could be a dog or a mouse or a bear, but more importantly... It's me, the principal!"
He jumped off and stood on the bed Midoriya was resting on. "Due to special circumstance and seeing you so downt-rodent, I shall tell you that you passed with 70 points."

"But I didn't defeat any of the monsters…"

"Normally, getting zero points in the practical exam will result in failure… but villain based points are not the only points calculated in the exam after all, a hero course that rejects people who do the right thing is no hero course at all." All Might turned into his muscular form and extended his hand forward. "Come now, Midoriya Izuku. This will be your hero academia!"

Midoriya Izuku's POV

"I… All Might...I...I." I couldn't speak, there was a lump in my throat, my tears won't stop dropping. I … I passed.

And I realized, through all of that chaos, all of that emotion, all of that pain and hard work, that even though I was not born equal to everyone else, that my stating line was further away than everyone else, I still had a starting line and with that, I realized this was the beginning of my story, The story of becoming a great hero.

Author's note

After seeing Chapter 214, I wanted to explore the things One for All could have potentially become and decided to use the idea that being quirkless had merit in being a catalyst for the evolution of a quirk so this will be the premise of the quirk known as Once And For All. This won't mean that Izuku will be overpowered even if he is able to control his power, he can't control the after effects of his quirk.
