A/N : Hello, this is the first time I'm writing a fanfiction. I hope it's not too bad, I don't know how long I'm going to be writing this, but I hope y'all enjoy reading this. I'm also writing this because I don't see much Deku/Jirou things, so I figured I'd just make one. I don't know if I'll do one shots or multiple, I don't really know where the story is going to go, but enjoy.

I'll also be skipping some things that are in the anime and I'll be adding in my own scenes/parts into this story. And I'm going to make him get stronger faster, I hope y'all don't mind, I don't really want him being broken too much. And Midoriya knows All Might is teaching at UA. And his mother knows that he's been training with All Might, so the people in the anime/manga that knew, except Bakugo, know along with Inko Midoriya. Midoriya also doesn't stutter as much or get as nervous, but he does trip up on words, it's only because I don't like to write stutters.

My name's Izuku Midoriya, and this part of my life is when I inherited the quirk of the greatest hero, One For All. My mentor and predecessor All Might found me, after trying to save a childhood friend/bully. He asked me why I did it, and responded by saying my body moved on it's own. After years and years of being quirkless and being told I couldn't be a hero, my idol had proudly told me that I can! From then on I trained by cleaning Dagobah beach, weeks and weeks of adversity, I transformed myself from a twig to having a base to receive my soon to be quirk. Training to go to UA, the greatest hero school in the east of Japan. Finishing up the beach clean up as training, I was ready to receive the quirk, One For All. I had a month to spare and All Might was astonished with the rate at which I finished. He looked to me, and proudly said I was worthy to inherit his quirk. He plucked out a strand of hair and handed it to me and said.

"Eat this!"

I was taken aback by this.

"You need to consume some of my DNA in order for the quirk to pass. Don't worry, I made sure to clean my hair this morning, Young Midoriya"

"Okay All Might, I trust you."

I took the hair from his hand, and swallowed it. All Might had given me some water in order for it to go down easier, I thanked him for that. He also reverted to his Small Might form, a name I gave the form.

"So what now?" I asked

"Well we wait, Young Midoriya. Thankfully we have time until the UA entrance exam. If you want I can put a word to the principal that your my successor, don't worry he knows, and we can try to get you in through recommendations! But I'd also like for you to take the entrance exam just so that people don't think something fishy is going on that could jeopardize our situation" All Might, in his Small Might form, stated.

"Thank you All Might! I will gladly take this opportunity to get in through recommendation and take the exam so no one thinks something is going on with us."

"Thank you for taking a chance for a recommendation, Young Midoriya. I'd like for us to go train you at UA, you've inherited the quirk, and made a fine body, but one that was rushed. I'd like for us to train there since we can do it easier than here in public. If that is alright with you, Young Midoriya."

"Alright!"

"Fantastic, quickly, we must be off now. I am so proud of you."

After a quick car ride with All Might, we arrived to UA. And we went to Ground Beta, a city layout. All Might and I arrived and walked towards the center of the training facility. He wasn't in his buff form, but he wore his hero costume that fit him super loosely. All Might told me,

"Alright kid, ask me anything you want to know about your quirk."

"Okay, well, how do I use it? How much power do you think I'm able to use? How do you use it? Am I going to die if I use it?" I asked.

"To use One For All you must clench your buttocks and scream within you heart 'SMASH!' What I can estimate, you're only able to use about 5-10% safely or comfortably. If you were to use 100%, well, you'd probably severely break your arm and you won't die to answer one of your questions. I was pretty much able to use One For All right off the bat, but it's a different strength comparison to when I received it, I built up my strength and mastered it. You've got the same strength at 100% as I did in my prime. And from that you'll become even stronger. You don't need to worry about not getting it right the first time, you have some time to master it. And some advice, your quirk is a part of you, it's not like needing to 'borrow' it. Think of it as a muscle, you have muscles all over. Don't 'turn it on' in a localized area, have it course through your body if you can catch my drift."

"Alright, so I won't die, it'll just hurt a lot if I use 100%. 5-10% isn't too bad considering how strong you were in your prime," I mumble to myself. "So I course it through my body, like the way how pizza is warmed up in a microwave, heat is applied everywhere as it's on."

"Crazy simile but go for what works man!" All Might says as he puts up a thumbs up for me.

I walk over to the middle of an intersection and All Might is on the corner, beefing up incase I do something reckless.

Course One For All throughout my body, and maintain, I'll do the most he said I could do currently, 10%!, I thought to myself.

I think about the pizza and the microwave and I feel the power coursing through my body, lines of power show up and envelop me, I feel the warmth it gives me, I feel this power run through me and once it's done a glow envelops me and electricity is emitted from my body. I'll call this One For All : Full Cowling!

"Young Midoriya! That's quite the flashy quirk you've got there, and I'm sure it's powerful. Bound to make you popular, flashy and powerful." Boasted All Might. "But now the question is, can you move?"

I take a step forward, and another, and another. I'm glad I know I'm able to move, but how fast can I go like this? How high can I jump like this? How hard can I hit like this?

"I can move, All Might!"

"Good!, let's see how well you're able to move and perform with a quick Quirk Apprehension test!"

I powered down and followed All Might to a small field with tracks and measurement tools for a simple physical test he'd done poorly on in middle school. All Might went to go quickly change and came out in a white shirt and baggy cargo pants, he also powered down.

"Alright kid, show me what you got!"

I went and powered up to do the 50m dash, the standing high jump, the grip test, the softball throw, and many other tests. I noticed I had a stamina increase along with increased strength and speed. A simple superpower quirk, I also remembered I'd need to update what my quirk is on official papers, and make plans on a hero costume, I can get help from All Might on that!

I finished the test with great marks, reaching around 2.3 seconds on the 50 meter dash, and around 715 meters on the softball throw, but I went a little overboard on the throw.

"Young Midoriya, this is incredible! I would say ease up on your power output, it was easy to see when you went over your 10% limit. I don't want you hurting yourself so soon." stated All Might.

"Thanks All Might! I'm quite surprised as well! This is a major jump from my middle school scores! And I'm sorry I went over my limit, I'll restrain myself," I responded. "Hey All Might, do you mind helping me update forms for my quirk?"

"Of course! I was prepared for this actually, come to my office and we can do it quickly together!" informed All Might.

After filling out the forms and submitting them we also got to work on the recommendations with Principal Nezu. Once that was complete I went home and arrived to my mother making my favorite meal, katsudon! During dinner between my mom and I, I informed her about the events of today, getting my quirk, going to UA on recommendation and needing to go through the entrance exam, along with the quirk apprehension test. She was surprised with the events and proud and blessed of the opportunities I've been given, to pursue my dream of being a hero who saves others!

After dinner I went to change, wearing simple black shorts with a green shirt and running shoes, to go take a run. Hoping not to see Kacchan around I went to run by Dagobah beach. Once I arrived I put on my headphones, and listened to some music to pump me up and keep up a good pace. On my run I noticed many people, I was also tempted to use my quirk but it's illegal to do so. On my run, I was thinking too much in my head about the applications of my new quirk, it's a strength enhancer, but could it enhance other parts of my body? Too wrapped up in my thoughts I didn't notice until it was too late that I was going to bump into someone.

"What the fuck man?! Watch where you're going!" shouted the stranger.

"I-I-I'm sorry! I d-didn't mean to crash into you!" I apologized and stammer a little, looked at the stranger and noticed it was actually a girl. With purple asymmetrical bangs, and what looked like, headphone jacks earlobes on her ears? She noticed I was staring for a bit too long and even I noticed, as both our faces turned a bit redder. And one of the earphone jacks extended and stabbed my forehead, not puncturing my skin, but it really hurt.

"What the fuck are you staring at?" She rudely asked

"U-uh-uh, I was just noticing your hair and your ears, is that your quirk?" I quickly stated while placing my hand over my face in case she stabbed me again.

"Yes it is," she pulls back her headphone jacks. "Did you not notice me, or notice where you were running?"

"W-w-well, to be honest no, I was too caught up i-in my thoughts about my quirk, you see, I'm a late-bloomer and only recently it emerged, so I was c-caught up in my thoughts about it."

"A late-bloomer?" she looked puzzled. "So then what's your quirk? You already know mine, it's obvious."

"W-w-well, my quirk is called Superpower. It's an enhancement quirk. It's very powerful and I need to watch myself or my arms will break." I stated, "The amount of power I can output is probably why I'm a late bloomer. But it's weird since my mom has a form of telekinesis and my father, who's overseas, can breathe fire. I'm rare with being a late-bloomer and having a different quirk than my parents. I also kind og glow, so it's also flashy when I use it."

(Jiro's POV) I was shocked at this, I thought,'Is this kid serious? He looks so plain to have a quirk as powerful as he states, sure green hair isn't plain, I have purple hair, but he looks too plain. He has what sounds like a heroic quirk, I should ask him what school he'll be attending for high school, I'm trying for UA, and he doesn't look half bad for being plain.'

(Back to Deku)

"What high school are you planning on attending?" the girl asked.

"W-what?"

"Geez, can't you listen? What high school are you planning on going to? You look about my age so I was wondering what school you're planning on going to." She loudly asked again.

"O-Oh, well I'm planning on going to UA, the greatest hero school in the east of Japan! I've always wanted to go there since All Might went there!"

"Interesting, I'm also planning on taking it, and the entrance exam is in about a month from now." She looks at her phone to check the time. "Oh shit, well I've got to get going now, nice meeting you?"

"I-I-Izuku Midoriya!"

"Nice 'bumping' into you Midoriya, see you at the entrance exam, and if you wanted to know I'm Jiro."

"Nice to have met you Jiro!"

We went our separate ways, I continued my run and stopped a few moments after, blushing bright red,'I just talked to a girl!' I finished my run, went home, showered, and got ready for bed.

I was able to complete the recommendation exams quite easily, training with my 10% Full Cowling, I was incredibly fast, but not as fast as a kid who's quirk was able to control the wind, but faster than a dual haired kid who was the #2 hero's son, the son of Endeavour. He used ice to speed through, but I was just faster than him. Present Mic was there and I asked him to sign my hero notebook since I was a fan of all heroes! Once I got the signature All Might in his small form was outside of the school waiting for me. Asking how the exam went and I told him I placed 2nd in the practical and I felt confident in the written. Next I had to take the regular entrance exam which was next week. All Might recommended I get a haircut for when I take the regular since Present Mic is going to be the test proctor for that one as well. We went to a barbershop and I got a haircut that was cut short on the back and sides and trimmed the top of my messy hair, it didn't take long since the barber's quirk, Scissor Hands, made things much faster. Glad with my look and a thumbs up from All Might and the barber I felt confident with this new look.

Arriving back at home I told my mother as I helped her make dinner about the recommendation exam, and she was surprised and liked my new haircut All Might paid for, explaining to her that the test proctor would be the same and a haircut might help with not being suspicious. After dinner and washing the dishes I went on another run. This time not wrapped up in my mind I enjoyed the way the moving air felt around my newly shaved head. I noticed Jiro, I still remembered her and hadn't seen her since the first time we met.

"Hey! Jiro!" I holler out to her.

She looks in the direction of the my voice and has a surprised look on her face.

(Jiro's POV) 'Oh, is that Midoriya? He got a pretty nice haircut, his green hair was too wild before and he looks a little sharper, not so round faced. He's still running, oh no, is he going to run into me again?!' Midoriya stops just a foot away, and he's wearing some basic workout clothes. He unplugs his headphones from his ears and paused his music.

"W-What's up? Haven't seen you in a bit, and the exam is in a week! Are you feeling prepared? Are you nervous about it?" Midoriya asked so quickly

"Nice to see you again Midoriya, I'm feeling both excited and nervous about the exam. I feel just about prepared. I'm not really sure what to expect from UA." I state calmly.

"I'm sure it's nothing too crazy, I'll be there to cheer you on, I'm sure you're gonna do great!" He said so brightly I had to look away for a second.

"Thanks, I barely know you but I'll cheer you on too, late-bloomer." I jokingly say at the end.

'Wow, haircut and some more confidence, I wish that would happen when I get haircuts. I usually get super shy and embarrassed. He also doesn't seem to be stuttering with me ask much.'

(Deku's POV) 'Is she gonna call me late-bloomer? Well, it's better than Kacchan's name for me, Deku.' I notice she gets a laugh out of calling me 'late-bloomer'

"Late-bloomer, huh? Is that my nickname now?" I ask with a smile

"Well, no, I just thought it would sound funny." She says. "What are you doing here? Another run? I was actually worried you would run me over again like when we first met."

"Oh no, I wasn't wrapped up in my thoughts like last time, a hero needs to notice their environment! Anyways yeah, I was just on my run by the beach, what are you doing here?" I notice she has a bag and dressed in two-piece swimsuit, after noticing what she was wearing I immediately blush.

"I was just going to relax on the beach and swim for a bit. Why is your face turning red?" She asks. "Oh. Oh!" She sends out her earphone jacks and pokes my eyes and I scream in pain.

"I'm sorry!" I repeat this a few more times until she stops poking my sides with her earphone jacks.

"Fucking pervert!" She yells, I notice she's blushing red as well. She's not as developed on her body as some girls her our age are, but she doesn't look bad, she's very cute as I notice her.

"I'm sorry!" I yell one more time before completing my run and shout again 5 meters way, "I'll still root for you on the entrance exam!"

I look back and see her red face has cooled down back to normal. I return home, shower, and received a phone call from All Might telling me I got in through recommendations and he asked if I was sure I wanted to take the regular entrance exam. I replied with a hearty yes. A week went by and I was standing at the gates and all of a sudden I hear.

"DEKUUU!"

'Oh great, it's Kacchan' I think sadly in my head

"H-H-Hey K-K-Kacchan! D-D-Do well!"

"Shut the fuck up nerd! You're just a pebble!" Shouts Bakugo.

I'm shaken up from seeing Kacchan again. I take a deep breath and walk towards the gate prepared for success, until I trip on myself and think 'I guess I'll just die instead.' Prepared for a bump to the head and a fall, it never came.

"Huh?" I was shocked, I was floating

"Hey! Sorry about that, would've been a shame if you fell on the day of the hero exam!" Said a random girl who had her hand on me.

I feel my face get red hot, I'm probably blushing really hard. She releases me from floating once I've adjusted my stance. I try to say something but can't get the words out. She gives me a bright smile and walks into UA. Once I feel my face return to normal I hear Jiro call out to me.

"Hey late-bloomer!" greets Jiro

"Hey Jiro, ya know, I don't have a nickname for you."

"Jiro is fine, no need for a nickname. I just call you that for shits and giggles." She beams me a small but noticeable smirk.

"Well alright, I'll think one one once we're both attending UA!" I say as I strike a fist into the air

"Wow, okay, great you're positive. I'm still feeling nervous. And by the way, what's a Deku?" Asks Jiro

I turn red and respond,"Oh, Deku, it's just a nickname a childhood friend gave me."

"Really? Deku? Doesn't that mean, like, useless?"

"I guess, but it's fine, it kind of loses some meaning over time."

"Alright, I won't pester into your problems. Anyways let's head on in, seems like we're some of the last few out here, other than these guys."

Jiro points over to some stragglers, someone with yellow hair with a black streak, another with black hair and weirdly shaped elbows, and someone with red spikey hair.

We walk in and sit next to each other after picking up an exam booklet with our names on it and we take the test for what seemed like hours but went by quite smoothly. Doing my best as I did on the recommendation exam. Once the bookelettes were collected Present Mic came out onto the stage and explained the practical. Some kid dressed in a business suit shouted about where the fourth obstacle was, a 0-pointer robot. Present Mic recommended that we stray away from it, it's just something that gives no points and doesn't take points away. Once we had all changed we took a small bus to Ground Beta. I noticed Jiro and the girl that saved me from embarrassment, I was going to walk to her and thank her, until the boy that asked about the 0-pointer held me back and asked if I planned to ruin others' chances on succeeding in the practical.

"No! I was going to thank her for what she did for me outside, it'll only be quick man, and my friend is there so I plan to give her words of encouragement." I say swiftly

"Oh! My apologies," he states and bows to me. "I did not know you were going to thank her and give encouragement to your friend! I give you much applause and I hope you do well! I am Tenya Iida!"

"Thank you! Nice to meet you, I'm Izuku Midoriya!" I beam him a smile, having no grudge as he apologized.

I walked and thanked the girl who saved me, stuttering through and I learned her name was Ochaco Uraraka. After giving her a stammered good luck I went to Jiro to give her good luck as well.

"Hey late-bloomer, came to give encouragement?" She asked with a small smile. "I hope you do well but I'm gonna go all out on this practical!"

"I was just about to say the same thing!" I say as I beam her with a small chuckle and laugh.

Present Mic yells that there's 15 seconds until the gates open and we start, I activate 10% Full Cowling, letting the One For All course throughout my body, with red marks glowing and fading leaving a bright light from me with bolts of electricity surrounding me. I receive many stares and glances, and even Jiro is shocked at what my quirk looks like from a stationary point. I did tell her it was flashy when I activated it.

STAAAAAARRRT!

Is what Present Mic shouted and I was already points ahead of everyone as I bolted to the nearest faux enemies and destroyed them

'This is kind of unfair but I can't let up! I have to prove myself I deserve to be here like everyone else!'
