It was a strange feeling to stand in UA again since he could help but remember the broken state it had been in the last time he visited.

The once impenetrable walls turned to pieces, pristine white halls stained in ash and blood, the golden gates bent beyond recognition. Sometimes, if he blinked, for a second it felt as if he was back there.

Izuku shook his head. Now's not the time to think about that because right now he was sitting in class 1-A waiting for his teacher to arrive, a small smirk grew on his face as he watched his classmates talk to each other, the excitement was almost palpable.

"Hey nerd, you're the one that knows about heroes, who do you think our homeroom teacher will be?" Kacchan looked back from his seat to him.

"I don't know Kacchan, but I have a feeling it's someone none of us expect" His answer got him a questioning look from his friend but he just gave him a knowing smile.

And just as expected, a tired voice rang out making the class fall into silence "If you want to make friends than you better leave"

Everyone turned to look at… the strange man in a bright yellow sleeping bag on the ground, the first time he had been too stunned to even realize just how weird this was. Aizawa, somehow, managed to stand and take the sleeping bag off and looked at all of them "It took you eight seconds to quiet down" he swears that when his eyes went over Shinsou, his gaze softened.

"I'm your homeroom teacher, Aizawa Shouta" He then shoved his hand into the sleeping bag and pulled out another bag which he then pulled out the P.E uniform… this was starting to give him a headache "Put these on and meet me in the P.E grounds in ten minutes"

He then walked out.

Everyone just stood frozen in place trying to process what it was that had just happened but their eyes then locked onto Midoriya as he calmly stood up from his chair and grabbed one of the uniforms before giving everyone a smile "Why are you all just standing there? Our teacher is waiting" Those words made everyone snap out of their trance and rush forward to grab a uniform while he just left with a smile.

If he was going to repeat school again, he'll at least have some fun with it.

--

The fresh breeze felt nice on his skin and it at least helped him ignore the fact that there were two teachers in front of him.

"You must be wondering why I brought you all here for" Aizawa once more gave all of them an annoyed look before continuing "You'll all be doing a quirk apprehension test" this got his class to burst into whispers.

"Except you Midoriya"

Silence fell on all of them and Izuku just looked at his teacher in complete confusion.

This was different, too different.

"You'll be doing something different with me and that's why I brought my coworker, Present Mic, to take my place for now" Aizawa explained but he kept his gaze on the greenette.

Mic smiled and pointed the students to another part of the grounds, the students gave him confused glances but Bakugo and Himiko were worried and he shared that feeling.

"Did something happen, Sensei?" he asked hoping that it wouldn't be anything bad but his hopes were dashed when he saw the look of suspicion his teacher gave him.

"You'll still be doing the exam, just a different one" He then gave him a creepy smile with too many teeth "You'll have a spar with me"

And that is how Izuku now found himself in a cement ring with his teacher on the other side "This test won't end until one of us gives up or is knocked out, understood?" his teacher asked and he just gave him a nod.

He slowly took in a deep breath. Last time, he had been too passive, he spent too much time running around like a headless chicken, his lack of action had cost the lives of others and even gotten his friends injured but now…

He let the air out. This time he would not hold his punches.

"You look like you are ready" His teacher said, his eyes already shining a crimson red.

He chuckled "Fighting a pro hero is a great honor, so I'm really excited" He could already feel the fire that were his quirks being snuffed out by Erasure but that only made the smile in his face widen.

"Let's see what you are made of."

Aizawa took the first move and sent his scarf forward, he had read Midoriya's file multiple times, his quirk was an emitter type that allowed him to control fire so he was most likely used to keeping the distance but he already had his quirk erased so he'll just panic and- What!?

Aizawa was taken aback when Izuku dashed forward and nimbly dodged his scarf without even a hint of his quirk and then threw a right hook at him.

He blocked it and sent a kick at the boy, but he ducked and sent an uppercut at him, Aizawa leaned back barely dodging the attack but that's when he felt it, the heat.

He jumped back just to barely dodge the wall of fire that erupted in front of him, the intense heat forcing him to cover his face, only to shortly realize his mistake when he felt the pain from the kick he received on his side.

"Rule number one in fighting Eraserhead, always keep an eye on your opponent!" Izuku boasted as he used the fire he shot from his feet to speed up his momentum and move to his teachers blind spot just as they moved to erase their quirk.

He had already fought Aizawa multiple times in his life and while he had only come to defeat him a handful of times, he had learned more than a few tricks to deal with him.

While he was a great fighter, fights that span for a long time are his weakness, since he has dry eyes he can't constantly use it before he has to blink and lose line of sight, so the most important thing in a fight against him is speed.

He needs to stay in his blind spot and use any moment where he isn't looking at him to use his quirk and tire him out.

It was a rough but effective strategy he had made years ago.

He send another boosted kick to his teachers back, sending him forward but Aizawa isn't an expert for nothing as he tucks and rolls before getting back into his feet and erasing his quirk once again as the flames died out.

Once again Izuku ran forward and concentrated on the gray scarf that shot forward to grab him. Aizawa's binding cloth fighting style had been something that he had already seen millions of times and had even helped Shinsou perfect his mastery over so while he didn't have a perfect plan against it, he was able to analyze the trajectory and move his body to dodge the restrains before going in for another punch at his teacher.

Aizawa already raised his right ready to block the right hook only to realized that it was a faint and block too late on the left and receive the left hook right to his face sending him to the ground.

Izuku took the chance and put a foot lightly on the fallen teacher's chest before summoning fire on his palm pointed at him, a wide grin on his face as excitement shone in his eyes.

Aizawa could barely keep his eyes open from the heat and by how much his eyes burned from overusing his quirk, he hated to admit it but, the kid won.

He let out a sigh before lowering his head to the ground "You win Midoriya, I give"

Izuku chuckled a little before taking his foot off his chest and offering him a hand. Aizawa was surprised at the strength he had to easily pull him up.

"If I may ask, why did you want to spar with me instead of the normal test?" Izuku asked.

Aizawa just sighed, he had lost, the kid at least deserved some answers "Because your file was too weird"

"My file was… weird?"

"Yes, the idea of someone getting their quirk at the age of 15 is unheard of so it raised some suspicion, and even now in our fight, you fought like an expert"

Izuku couldn't help but smile, he had expected a reaction like this since he had a similar one before.

"Yeah I can see why it would be weird but it all has a really simple explanation" Izuku admitted.

"Well, I would love to hear it" Aizawa crossed his arms while looking at him.

"Like my file says, I only got my quirk less than a year before the exam so I spent my entire life as a quirkless" Izku looked down at his fist "I was heavily bullied because of that and even more for my dream to be a hero, for a long time I didn't do anything, I just let them kick me down to the ground but one day… I got tired of it."

"I decided that if they were still going to bully me I would at least make a good show of it, so I began to train." He then turned to his teacher who looked at him surprised "My life from then got a lot more messy and even more after I got a sister"

Aizawa nodded "But what about your quirk?"

Izuku smiled "I'm getting there but first, Sensei, have you heard about the 'forced awakening' theory?"

Aizawa raised an eyebrow, it sounded familiar but just that, so he shook his head.

"The theory stated that quirkless children like me aren't entirely quirkless like one may come to believe, instead, it says that we do carry the quirk factor in our genes just that it's asleep, like how your recessive and dominant genes decide on what color your hair is" Izuku explained.

"But it also says that those with a sleeping quirk factor are capable to awaken it after going through an event that puts them under intense feelings of stress" Izuku watched as his teacher's face filled with understanding and looked at him with surprise.

"So you…"

Izuku sadly nodded "Yes, one day after school, me and my sister had an encounter with a villain, he made his intentions of killing us clear and I panicked, all I could think in the moment was 'I can't let my sister get hurt' and then…" he snapped his fingers and made a small flame appear as an example.

"Since then, I spent my days practicing. Having a quirk had been my biggest wish so when I got one I couldn't help myself from seeing what it could do and…" He looked at the small flame he had made before snuffing it out on his hand "I knew that I would be at a disadvantage compared to others since they had their entire life to train and learn them and I only had a few months before the exam so I had to put all of my effort into it"

He turned once more to his teacher with a smile "Was that a good answer?"

Aizawa looked at Midoriya once more and felt as things began to make a lot more sense to him, maybe he had misjudged too fast, the case about Remnant and AFO had been putting him on edge and he jumped on the first suspicion he had on a student.

He sighed "It was, and you have also shown me that you have a lot of talent, now come on problem child, the others should be finishing soon"

Aizawa couldn't see it but at the mention of the nickname, Izuku smiled brightly as he followed closely behind.

--

The next day came with a blink of an eye.

For Izuku, all of the classes began to blend together since his knowledge on the subject was already a few years ahead but his attention was set on the last and most important class of the day.

Heroic studies.

The class that was supposed to be taught by the one and only All Might, enfasis on supposed.

Because once again, Izuku was looking at another change in the timeline as both All Might and Aizawa stood in front of the class.

The students kept quiet as Aizawa gave them all a steady glare but the excitement from seeing the number one hero was still obvious in their shining eyes.

" WELCOME STUDENTS TO THE HEROIC STUDIES CLASS!! " All Might loudly exclaimed.

" IN HERE, WE'LL BUILD THE FOUNDATION TO YOUR HEROIC SPIRITS!! AND TO START IT OFF WE'LL DO A -" "We'll do a battle exercise" All Might was interrupted by Aizawa who was glaring at him while covering his ears.

"This will also be the chance for all of you to try the gear that you requested" the teacher then pressed a button on their remote that caused panels on the walls to open and release metallic suitcases on everyone's desks.

Izuku smiled as he looked at the suitcase and remembered the times he spent with his sister throwing ideas at each other on how their suits could look until they both came to some satisfying results.

" SO PUT ON THOSE SUITS AND MEET US AT GROUND BETA! AND DON'T FORGET THAT FROM NOW ON ALL OF YOU ARE OFFICIALLY HEROES!!! " All Mights booming voices bounced around the walls as the students hurried to the changing rooms, all burning with determination in their hearts.

--

"You look great kiddo!" Nana said as Izuku looked at his reflection in the mirror after putting on his new hero costume.

This time, instead of letting his mother make him one, he had sent it to one of the different companies that helped UA and was glad that they didn't disappoint.

He kept the normal full-body jumpsuit but this time it was a dark red with white accents, weighted fingerless gloves and armored shoes to pack a punch when he fought hand to hand. One important detail was that around him there was an exoskeleton that was supposed to help him move easier but that was just a lie, it actually held no purpose whatsoever but it worked as a great cover for when he used One For All.

But the most important thing wasn't the suit, it was the black suitcase next to him that filled him with excitement. The day before he had left a request to the support department and asked a specific pink haired mechanic to help him build a few support items. The ones she had given him were prototypes but if they worked like he had asked then they could give him a whole new boost in battle, but for now he waved it away letting the sludge teleport it away, he'll wear them soon enough.

He finally left the changing room alone and headed to where his class was going to be held. In a few minutes he found his classmates eagerly talking to each other about their new costumes.

"Izuku!" Himiko ran over to him and tackled him into a hug and he did his best to hug her back while avoiding the spiky parts in her costume which were… a lot. "This is so exciting!! We are actually wearing our own hero costumes!!" Himiko was at the verge of exploding from happiness.

Her own hero costume was a red bodysuit with black and white accents, around her waist is a belt with different pockets most of them filled with sharp objects and some with first aid, under her best is where a skirt that reached beneath her knees began, the outside color of it being black but on the inside it shined a bright blood red. She also wore white weighted fingerless gloves and armored shoes similar to his.

One key factor about her suit is that when they were throwing ideas at one another Izuku decided to steal one from the girl herself from when she was a villain and recommended the same machine she u sed. So now she carries three large silver canisters with needles poking out on her belt which connect them to the two larger cylinders strapped to the back of her belt.

"It- it looks great" he said turning away trying to hide the smile on his face as he saw the similarities on their costumes but he knew he failed when she giggled.

"Sensei! Regarding the performance ground we'll be using, is it the mock-city from the entrance exam?" Iida asked, his voice slightly muffled from the suit of armor he was in.

"While it would be good to use those more than once a year, UA prides itself on making sure their students are ready for anything, so this one will be an indoor battle trail" Aizawa explained before glancing at All Might who smiled brightly at his co worker permission to blow his eardrums.

" AND FOR THIS TEST, YOU'LL SEPARATE INTO 'VILLAIN' AND 'HERO' GROUPS FOR A TWO-ON-TWO BATTLE!! " All Might loudly explained.

"So how do we determine who wins?"

"Is it okay if I just blow them away?"

"If we are separating into groups, what would be the best way to do so?"

"Doesn't this cape just look exquisite on me?"

"Ugh, one at a time" Aizawa grumbled "The students on the villain team will have to protect a fake weapon while the heroes try to stop them. If the heroes manage to capture the villains or get to the weapon before time runs out then they are the winners, but if the villains manage to keep the heroes away from the weapon or capture them instead, then they win"

" AND THE WAY YOUR TEAMMATES AND OPPONENTS ARE GOING TO BE CHOSEN IS… BY LOTTERY! " All Might said as he pulled out a box with a hole on top and placed it in front of him.

"Is that really how we'll do it!?" Asked Iida in mild surprise.

Izuku chuckled a little at seeing how green his friends were to everything again "This is actually a really good idea, usually in cases like these, pros don't get to choose their partners and are forced to adapt around them, so doing things like this would be a great way to test that" he happily explained.

"Thank you for explaining problem child, now stop wasting time and get over here"

Izuku stuck his hand inside and pulled out a blue ball with a white letter A on it, he smiled fondly, guess somethings can't be changed, but he did wonder who his teammate would be, he knew everyone here inside and out so he should do a go- "Oh Midoriya, looks like we are in the same team" he turned to look at the girl with orange hair and turquoise qipao with a forced smile.
