Hey! So, it's my first time posting a story...also english is not my first language.

I hope you like my work!

I've always wanted to write some fanfic about Boku No hero Academia and I'm in love with the medieval AU since I saw ending 3 "Datte Atashi no Hero".

New life and a friend from the past

She never thought that she would end up like this, dead and it's because of that bus that appeared in front of her. She was walking down the street on her way back from returning a book borrowed from the library.

Just a few hours ago, she was a normal teenager that was studying for final exams.

Books gave her freedom from those boring mathematical problems and sleepless nights of studying. You could go everywhere, be it a romance story or a fantasy one, with knights in shining armor, dragons and princess.

"I know, cliche but a girl can dream..my head hurts, everything hurts like fucking hell" she mutters.

The feeling stopped.

She is in some kind of a dark corridor that has no end. She rubs her eyes to at least improve her eyesight and perceives a wooden door at the other girl is getting closer and closer. Someone is calling her name but at the same time it doesn't belong to that girl, very familiar. When she is about to touch the door a middle-aged woman opens the door. She's a short lady with green hair and a gentle look on her eyes, she likes her already.

"Izuku, breakfast is about to get ready!" She closes the door.

Huh…

She turns on both sides and recognizes that it is a bedroom. Just a single-bed, a wardrobe, a desk with some books, a small dresser that faces the bed along with a huge mirror on the wall. This is not her body, she used to have a simpler appearance, brown hair, dark eyes and an average face. Now she possesses very wild green curled hair and big eyes of the same color along with cute freckles on her cheeks.

That's when it clicked, that's why it was so familiar to her, recently she read a book named 'My hero' that was dated in the medieval ages but with a little detail, there is magic and it doesn't matter what type everyone has it but some people have more than others.

The story unfolds around five characters, a knight who possesses amazing speed, a prince who dominates ice and fire, a magician who dominates gravity with the things her hand touches and a dragon prince who causes explosions from his hands along with his dragon. They take the path to stop the greatest enemy that dominates the darkness, they call him master, well no one knows what exactly his power was and for that they have to find the greatest hero of all time, All Might. These two had a battle many years ago that left them both badly wounded and both disappeared. This is where this girl enters, Izuku Midoriya, one of her followers who carried evil everywhere on behalf of the master while he sees from the shadows waiting for All Might to disappear from the map and return.

"A little coward if you ask me," She mutters "The events of me being a villain should not happen yet because I remember that Izuku became evil because of the death of her mother at her village, for not having the ability to protect her and without a father or other familiar in her life she was left alone." She was running away from a thief and killed him with her powers to protect herself, people marked her for a murder. Someone from the past came back, not a good person… Hisashi Midoriya.

Her father disappeared many years ago, it turned out that he sided with master and returned to take Izuku to the villain league. She learned how to kill, she was very good at summoning powerful creatures and could levitate things with her mind. Sadly she dies by the hands of the master cause she hesitated to kill All might in the last battle, I guess she was not that evil. That was basically the first book with All might defeating the bad big guy with the last bit of magic left in him.

"So, I just have to practice my magic, levitate things...damn how cool is that?!," She always wanted to have powers and save people who needed help just like the movies with a smile on her face. In her previous life, when she was twelve years old, her family was caught in a fire in our home while she had to go to the store that was nearby. When she returned, the house was almost about to collapse and the firemen did not let her in to save them.

This time it won't be the same if she can do something about it.

Her name is Izuku Midoriya and her new life just began.

Getting out of the bedroom she quickly finds the dining area, breakfast already set,Inko Midoriya, she is her mom the lady from earlier that is humming to a song, she doesn't know what came over her, she hugged her.

"Why the sudden hug of my lovely daughter? Not that I'm complaining...did you had any sort of a nightmare?"

"You could say that...I just... I love you mom." She smiles, she means it.

"Me too, my darling!" She smiled so kindly and squeezed back.

"Let's eat or the food will turn cold."

"Indeed...Oh I almost forgot, what would you like for your sixteenth birthday?" She asked so spectantly with big eyes. Hearing no answer she puts her hand on her chin thinking and then clasps her hands together making a loud sound as she smiles. "Right...when you were younger you told me that you wanted to become a hero, you can enroll at the Academy."

Of course, in this world people have powers, because of that they created academies to train their powers and become heroes. Anyone can enter and there is a famous academy nearby called UA so it's a perfect opportunity to become stronger but…

"What happens if I go there?...I won't be able to save her." Her worries come out.

Let's stay out of the plot events.

"I did?"

"Yeah, you used to play with that kid from the dragon tribe...kacchan it think it was his nickname."

"Uuuh d-dragon tribe?" Izuku asked with a crooked smile and alarmingly tried to recall that name somewhere but nothing came.

"His name is Katsuki Bakugou, the crown prince from de dragon tribe here from the Badlands."

That's when a few images appeared in Izuku's mind from a boy and a girl playing in the forest, blurry ones. Then she felt a strange fluttering feeling in her chest.

They knew each other? That was not part of the book.

"I just recall a few things." Izuku bites her bottom lips nervously and looks away.

"Well you were pretty young, like six years old and you haven't seen each other for 10 years."

"That's long... I don't think he will recognize me after all these years."

"He will."

"How confident."

Her mother points Izuku's neck, more like the thing around her neck. It's a simple necklace with a little pendant of the same color of her eyes.

"He gave you that necklace, it's a traditional ornament from his tribe and curiously it's the color of your eyes."

"Uh...waaah I'm sooo full so I'll do the d-dishes!"

The woman just laughs at her daughter's embarrassment.

Izuku runs to the kitchen trying to hide her red face, having a particular thought over and over again.

What are the odds to see him again?

Izuku started to train her magic in the forest, five months ago she could levitate little things like little rocks but nothing more. Now she's able to move heavy objects or even herself at the same time, she's a fast learner.

Some attacks have occurred near her village, they have been looking for someone with the same features, blonde hair and a height of about 6 feet or more.

They're looking for All Might.

In one of her trips through the woods she discovered a small waterfall about five meters high piled high with rocks that climbed high into the forest and mountains of the badlands.

Maybe she shouldn't go any farther because according to the book she remembered how close dragons live in the Badlands, which means the dragon prince Bakugou Katsuki could be close.

That's not a good sign.

The book says that he was a very explosive man, she wondered how it goes pretty well with his powers. He has blonde hair almost going to ash, with crimson red eyes and an almost barbaric way of dressing.

"I mean he is shirtless all the time...not good for my eyes and my maiden heart." She muttered under her breath.

She touches the water near a big rock and from the looks of it the water is not very deep so it is perfect for swimming.

"I might just explore it!"

There are no bathing suits here and definitely she won't get into the water in mere underwear so in simple pants and a t-shirt will do. Then out of nowhere a emerald little lizard with wings steps over the rock in front of her, making her jump backwards.

"What the fuck?! that's a freaking dragon!" The creature only observes Izuku with it's dilated eyes, his pupils are only a thin line and moves his head from side to side looking for something in her eyes. After a few seconds, apparently he finds it since his eyes returned to their natural state and approaches her. He just purrs at her sides and starts to rub its head against her legs.

"What a cute baby dragon...I guess we are friends now." She scratches his back.

A loud explosion from above.

"Oi! where are you, you little lizard!" The dragon hides behind her, like playing hide and seek.

That's a male voice, she cringed. "Wait a damn minute, I'm not your hiding spot!" She whispered tensing up while getting up, alert.

A big shadow lingers above her head, more like in the sky and she looks up. It's a big red dragon with a person on its back, she can't distinguish who might be that man and she hears another explosion. The man jumps, he lands on the ground with a strong boom leaving a hole from his landing and she opens her eyes wide, waiting any way to escape.

Again, not a good sign.

"What do I do?! Oh fuck he might think that I stole him" her thoughts screamed in her head.

Neither of them take their eyes off each other. As he approached Izuku, every muscle and every fiber of his body appeared to strain to force out his next movement ready for any possible fight.

"He has the most beautiful crimson eyes…" Her thoughts betrayed her.

Katsuki held up his hands, his palms crackling. She immediately started to feel the presence of things around her in case she needed to fight but she preferred not to so she held her arms in a sign of surrender.

"Where's Kaia ..? depending on what you say ... you'll live." He growls.

The cracks from his palms stopped.

Curious, Izuku roams his face with her eyes to notice that he is looking at the necklace gaping with his mouth.

"...Deku?" The blond man asks with a deep voice.

When she was about to open her mouth the little bastard started to roam all over her body like some monkey, now she really looks like she stole him.

Run.

And boy she ran.

"Oi stop it! Fuck!"

While running Izuku turns to look back and all she sees it's a demon.

Scary.

"Begone you demon!" She yells and then she hears a loud explosion.

He caught her.

They rolled to the ground and fell together down the hill. Izuka found herself on her back, Katsuki above her, with his hands holding down her wrists. Both of them gasping, taking in deep drags of air, drags that smelled of ash, nitroglycerin, mint, a smell of earth and skin. Their chests raising and falling. Izuku could feel the power in his thighs against her holding her in place. Katsuki was gritting his teeth, as if he were in a battle. A moment that felt like hours, Katsuki and Izuku stared at each other trying to memorize their features, afraid as if any movement would cause someone to disappear from their field of vision. Katsuki decided to break the silence and smirks.

"I know it's you shitty Deku…I would recognize that necklace anywhere."

"...K-kacchan?"

"You've changed."

"Well it's been 10 years, of course I've changed ... you've changed too." Izuku replies nervous and looks to the side."Um...I didn't steal him."

"Hah?!"

Izuku gathers courage to look up into his eyes and answers almost breathlessly."The baby dragon".

The moment she mentions her little friend, somehow the dragon finds its way between the two of them breaking the spell. Katsuki grumbles and stands up looking at the dragon in Izuku's lap.

"Just for the record, Kaia is a female."

Izuku looks at the dragon confused and pouts. "He's a she?!". Katsuki chuckles and approaches her.

"It's your first time seeing one isn't?" He reaches out his hand to Izuka and she takes his hand gladly standing in front of him.

"Huh...yeah… I mean I've never been in your tribe" She scratches her cheek with her index finger nervously and Katsuki tenses up. "How come she's here and not...in your tribe."

"Lately they've been robbing the young ones in order to dominate them better and use them to search for …"

"All Might...he came back."

"There has been circulating rumors that he has returned to save towns, but he disappears the moment he finishes the job." Katsuki glanced back up the hill from where they fell. "Let's go back."

Izuka started to climb back but Katsuki stopped her grabbing her hand and held her against his chest.

"Put your arms around my neck."

Izuku hesitantly hugs his neck looking up.

"...Kacchan no."

"Kacchan yes." He imitated her with a squeaky voice and kicked the ground with a loud boom.

"Noooooo!" She cried out while being suspended in the air and notices that Kaia is flying at her side following them towards the red dragon. There was a small crack and then landed on the dragon. They sat with Izuku in front of Katsuki, he grabbed the pointy spikes on the dragon's head and she could feel a strong arm surrounding her waist.

"Wow wow wow wow wow Where are going?! This is not my way back home."

"To the Dragon Tribe...ppf obviously." He snorts as a matter of fact.

"What?!"

After 15 minutes they landed on a very lively town, full with a lot of dragons with different colors and sizes. A very excited Izuku livitates herself off the dragon leaving a very amused Katsuki with his extended hand towards an empty spot. It brings to him a smirk to his lips but it fades just as quickly as it appears.

"Is this the famous Izuku of the forest?" The voice is a deep rumble, emerging from somewhere low in the dragon's throat, he shifts into a man with red hair and eyes. "Names Eijiro Kirishima" He said while pointing to himself with his thumb.

Amazing. That's all he can think.

"Um Izuku Midoriya...a pleasure."

"Fuck off shitty hair!" Katsuki snaps.

"Hey I'm a man for only one woman." Kirishima from the corner of his eye spots a woman with pink skin walking by. "Ashido, wait up!... nice meeting you Midoriya" He said and ran towards the woman.

Katsuki just grunts a reply and faces Izuku.

"Didn't know you could levitate yourself."

Izuku turns on her heels to look around and glances sideways, smirking towards katsuki to say. "There's a lot of things you don't know about me…I can't for long distances though,been practicing in the forest on that."

The moment they start walking they hear a lot of screams in the distance.

They're under attack.
