Once upon a time, in a land filled with the weirdest creatures you could ever see, a small child was born brighter than the others. In a literal way. The child was the first magicborn. The magicbornes were able to use surnatural powers unlike anyone had ever seen.

This caused panic in the villages and kingdoms across the land, even so when more and more childrens became magicborn. A large number of citizens decided to shame them for who they were. But others, mostly parents of the magicbornes, decided to accept them.

The discrimination lasted for many years. When someone decided to call the powers given to these childs "Quirks". Then during those dark years something happened. A woman with hair white as the snow gave birth to two small boys dying in the process. One was named Yoichi while the other's name was lost to time.

The nameless one had a quirk, while Yoichi didn't. Yoichi had a heart warm as the sun. While the no name had a heart black and cold as the darkest night. The boy without a name had the power to steal and give Quirks. He then decided to name himself "All For One(AFO)". He constructed his empire behind his brother's back. When Yoichi got notice of everything, it was too late. All For One imprisoned his brother.

After many months of psychological torture he decided to let him go. Only after forcefully giving him a Quirk of his own. A quirk that stockpiled power into any object he wanted but he only could use it on one object. What they didn't know was that Yoichi did, in fact, have a Quirk. He could transmit his quirk to any object he wanted. Which would give it to the new user and have the conscience of it's old user. This quirk and the stockpiling quirk fused together and created the quirk he called "One For All(OFA)" to contrast his brother. He then met with an old friend of his and told him to create the best blade in all the land.

He then gave the sword One For All and named it after it. He gave the sword to his friend, then killed himself. So that if AFO decided to come back for him he would be unaware of OFA and to be able to guide his next successor. Except he could not communicate with his successor, but he knew that someday one of his successor would be able to hear him.

Unfortunately, AFO kept a check on his brother so that he does not ruin his plan. And he saught One For All so that he could be truly immortal. For years OFA users tried and failed to defeat AFO.

Then one day, in a future where people called adventurers used their quirks to help people then were paid by the royalty and where Quirks were the norm and Quirkless people wasn't, the 7th user of OFA, Nana Shimura, found a Quirkless boy who wanted to help people but wasn't able to, because of his lack of quirk. Nana decided to train that boy so that he would become her successor. But one day before she could finish his training, she had to face AFO and died in the process before giving OFA to the boy. The boy finished his training with Gran Torino, a friend of Nana, then swore revenge for her old master.

The boy was renamed himself with the name everybody know. ALL MIGHT THE HERO! All Might rassembled a party for him to face AFO. Party composed of King Enji Todoroki, Shota Aizawa(Eraserhead) the Rogue, Hizashi Yamada(Present Mic) the Bard, Nemuri Kayama(Midnight) the Sorcerer, Nezu the Druid and Gran Torino.

After a long journey with lots of friendship gained, he and his party were finally at his lair ready to fight AFO. The fight was long and tiring, but at the end All Might's party finally putted an end to this. Finally able to rest, All Might died on the battlefield surrounded by his dearest friends. He was buried by his party, with One For All in his hands.

Many years after that battle, peace was restored. People lived their life in harmony. There were less and less crimes. But rumors says that All For One is still alive and is preparing his grand return. But a fearless adventurer will be chosen by the blade to finish him off once and for all.

Present time

A teenager was tossed around in the mud by bullies.

???: Agh!

Bully 1: Shut up, you quirkless loser!

Bully 2: I can't believe we breath the same air as you.

Bully 3: Maybe we should make him stop breathing! He's a waste of oxygen anyways!

The bullies started punching him in the guts until he puked his bowels out. Right in front of one the female bully.

Bully 2: EW! WHAT IS WRONG WITH YOU! YOU ALMOST PUKED ON ME!

She then kicked him in the face.

Bully 3: C'mon darling, let's get away from this waste of space.

Bully 1: Yeah just seeing him make me want to puke.

Bully 2: HEY! HE'S MY BOYFRIEND!

The two females were "good friends". Just tought you wanted to know.

Then the bullies took their leave. Leaving the teenage boy crying on the ground. That boy is named Izuku Midoriya and he is the protagonist of this story.

Izuku got up after a few minutes of crying an looked at his dirty clothes.

Izuku: How am I gonna explain this to Mom.

Izuku Midoriya is a boy who was, unfortunately, born without a quirk. For that simple reason he was bullied almost everyday. His father died in the battlefield before he was born. Leaving his poor wife alone to raise their son. She never quite moved on with her son being quirkless only adding to her daily stress.

Izuku walked in the street of his small village on his way to his home. He was often stared at. He didn't have many friends. More like he didn't have any friends. He had one once but he had to leave, since his parents went to another kingdom.

After a few minutes of walking, he finally arrived to his home.

Izuku: Mom, I'm home!

Inko: Oh, hello honey! How was your d-OH DEAR ALL MIGHT! IZUKU, ARE YOU OKAY?!

Izuku: Don't worry Mom. I'm fine.

The stressed out mother sighed in nervousness.

Inko: Well, let me take your clothes and take a bath while I wash them.

Izuku: Sure, Mom.

Izuku stripped in his undergarments, then went to take a bath and started reminscing that fateful day

In the past

Inko and Izuku were looking at the monk that was charged with finding quirks hiding in the child.

Monk: Sorry kid it's hopeless. You'll never be an adventurer.

Those simple words were enough to destroy the boy's world while the sound of his mother and the expert arguing were slowly being overwhelmed by a deafening sound.

In the cart on their way home, Izuku looked his mother straight in the eyes.

Izuku: Mom?

Inko: ...yes?

Izuku: Do you think I can be an adventurer?

His mother broke down and started crying.

Inko: I'M SORRY IZUKU! IF ONLY IT COULD HAD BEEN ANOTHER WAY!

Those were not the words Izuku wanted to hear.

Present time

Izuku finally finished to take his bath and joined his mother to diner. She made his favorite tonight. Katsudon.

Izuku and Inko: Thank you for this diner.

Then they started eating.

After having diner, Izuku went to his chamber and layed on his futon.

Then he heard whispers coming from outside his house. He was weirdly tempted to go find out what it was. So he did he got out of his futon. Took his recently washed clothes and got out to find the origins of those whispers. The whispers came from Dagobah Forest, a very dangerous forest that only skilled adventurer ever get out from, but it was as if he was hypnotized. He could not stop approching the whispers. After a while of walking, he finally found the source of the whispers.

A cabin with, inside, a relatively old man who looked like a skeleton who was holding One For All in his hands.
