(1 year later).

"So kid are you ready for the quirk?" Said Gran Torino standing in the UA gym and looking at him, next to him was Nighteye who was reading some documents on the Yakuza.

Izuku nodded his head while finishing tying his long hair in a ponytail, he was wearing a tank top and shorts that showed how well built he was, he was very muscular for his age but Gran Torino and Nighteye along with his dad made sure that he was more lean so he can be more flexible snd agile. He also stood at a comfortable 5,6 thanks to his diet, genes and training. Along his body were numerous scars from both training and his bullies from long ago, he had a one on his face which he was self conscious about but both Rumi and Ryuko said they liked it and it looked good on him.

Speaking of those two, they are both in the gym as well, Rumi has reached a height of 5'2 a couple months ago and hasn't grown a single inch since then which seriously pissed her off. Though her more feminine features have grown greatly which did make other woman jealous, both around her age and some older woman.

Ryukyu now stood at 5'4 and seemed to still be growing and much like Rumi her more feminine features grew greatly which did the same and both piss off and make other woman jealous.

Both of them were in training outfits which consisted of leggings and tank tops as well, but they both wore sports bra's which struggled to contain their bountiful chests (which they specifically wore to get Izuku's attention).

"Yeah sensei I'm ready" said Izuku as he looked at the small container in his hand that he's been training his body to be ready for; for the last 4 years. He opened it and with some disgust he ate the hair, though when he did eat it he felt a strange spark, almost as if something has always been missing from his life.

"Ugh.. tastes like lots of hair gel and spray..." Said Izuku in disgust.

"I still can't get over the fact it's transferred by eating hair" said Rumi "though if what the old man says is true that's how it's always been done".

A tick mark formed on Gran Torino's forehead "your walking a thin line rabbit, did you forget to eat your carrots".

A tick mark formed on Rumi's forehead now "that's rich coming coming you, or do I need to speak louder giving your old age".

"Oh please even with my age I could still kick your ass rabbit".

"Tough talk coming from a guy who has to eat soft foods, I already beat your record and now your just sour about it".

"Brat".

"Old geezer"

"Pellet muncher".

"Senile old man".

Both of them continued to insult each other and everyone could see a bolt of lightning going off between them.

"How long do you think they will be like this?" Said Izuku to Ryuko.

"Hmmm I'd say about 10 more minutes" said Ryuko with a light chuckle.

"Probably, so did you discover anything new with your training?" Said Izuku looking at her.

"Well Recovery Girl checked my throat when I was in my dragon form and found out that I can breathe fire if the organ she saw was what it was, though she told me trying to use it would be like using a muscle that's never been touched" said Ryuko.

"That's amazing Ryuko if yourabletodothatthenyoudbeevenhardertodefeat" said Izuku as he broke out into a mutter storm he tried very hard to control.

Ryuko looked at him and let out a small giggle, her and Rumi found his muttering to be cute, she honestly didn't know how people could find it creepy. She reached over and poked his cheek getting his attention.

"Oh sorry, I'm trying to get better control over that" said Izuku with a blush.

"Don't worry it's ok, besides it's cute" said Ryuko which made Izuku look away to try and hide his blush.

"So when will your dad and Emi get back from their honeymoon?" Said Ryuko.

"Hmm from what my dad said, either sometime this week or next week, just depends on how long they decide to stay" said Izuku.

"Hm I guess that makes sense, so are you gonna stay at your house or at me or Rumi's?" Said Ryuko as she played with a piece of her hair while looking away. But then her gaze went back to him and she had to bite her lip to not do what her instincts were telling her.

Before Izuku could respond he heard Torino's and Rumi's screaming.

"YOU SHORT LITTLE SHIT!!!".

"WHO ARE YOU CALLING SHORT? I'VE SEEN PILES OF SHIT TALLER YOUR SMALL ASS!!!!".

"WHY DON'T YOU COME DOWN HERE AND LET ME SHOW YOU!!!".

"OH ITS ON!!!".

"Not again..." Thought everyone watching this.

___

A couple hours later Izuku was standing in one of the more open training grounds, everyone else was standing behind him watching him to see him try and use OFA.

Izuku took a deep breath and thought of how Gran Torino explained it to him "I have to search deep within myself and find a massive well of power, then I have to will it to the surface".

After only a couple of seconds he felt it and it felt like he was standing Infront of a massive ocean of power, he slowly reached out and grabbed the power and it felt right, it truly felt like a piece of him that was always missing was now in place.

Everyone saw green and white lightning surround him, pink lines also started to form around his body as the amount of power he was grabbing was massive. Izuku then sent it all to his right arm and the amount of power he sent made it feel like his muscle fibers we're literally tearing themselves apart.

"SSSMMMMMMMMAAAAAAAAAAAAAASSSSSHHHHHHHHHHHHH!!!!!!!" Yelled Izuku as he threw his punch forward.

A massive air blast shot forth and destroyed everything in its path and even taking out 3 entire blocks of the training city before him. Once the dust settled they all saw the destruction before them and most were shocked at seeing the amount of damage Izuku did was beyond insane since it was just a single punch.

"T-that... That was on par with All Might's 100% Texas smash" said Nighteye in complete shock seeing this, If Izuku was this strong now, then he'd far surpass All Might by the time he reaches 20, let alone his prime.

The dust finished settling and they all saw Izuku on the ground holding his arm in pain, it war purple in color from being broken and some of the muscles were torn, his arm was also bleeding badly from the torn skin.

"F-fuck that hurts..." Said Izuku trying his best not to scream out in pain but finding it incredibly hard.

"IZUKU!" Yelled Rumi and Ryuko in horror seeing this and they quickly ran forward as fast as they could and grabbed and held him.

"Izuku are you ok?" Said Ryuko before she finally got a good look at how bad his arm was and her face got a entire shade whiter.

"Don't worry I'm here to help the young boy, though I recommend you work on the control so this doesn't happen again" said Recovery Girl as she kissed his arm which healed it completely giving Izuku's stamina that he's spent almost his whole life training for.

"W-woah.. I feel way more tired than normal.. said Izuku groggily giving the amount of stamina it needed.

"It's because it had to heal broken bones, torn muscles and skin, it's only thanks to all your training it isn't worse and you have enough stamina to stay conscious" said Recovery Girl.

"Mmm" he then stood up albeit a little wobbly but was able to regain his balance "so what will I do now sensei?".

"Now that you know what 100% is, I want you to train so you can only use the bare minimum, then we are going to work our way up until we know what your maximum is without damaging your body" said Gran Torino. "Once I help you out on your fighting style and control then Nighteye will take over to help cover any holes you will have".

Izuku nodded his head "when do we begin".

"Now, you have a little over a year to get as much of a handle with it as possible before the UA entrance exam".

___

(3 months later).

Over the last 3 months Izuku gained a massive amount of control over One For All, he was able to use 20% with zero strain but his vision couldn't keep up with it so he had to start with 5% and work his way up.

He also worked on making it so he could last as long as possible with his quirk active, so far he's able to keep it going for over 3 hours before he started to get fatigued.

Something else him and Torino noticed over the training was that he had a unnatural bond with the quirk, he didn't even struggle with learning how to turn it on and off. Not only that but Izuku told him that sometimes he'd have visions of people trying to call out to him, especially a white haired man with green eyes.

For Rumi she has been helping him find a good combat style with his legs since she trained to fight mainly with them, so far her training has been bearing fruit and he can use his legs just as easily as his arms.

For Ryuko she made amazing progress with her quirk and can now breath fire but it's only in short bursts and if she ate a massive amount of meat to act as fuel for it. Though she hated it since it made her feel bloated, plus she can only eat it in her dragon form or else she'd puke.

And with Nighteye hasn't been around as much as normal since he mentioned something about finding a student he took in as a intern and is currently in the process of training him. He also mentioned something about investigating the remnants of the Yakuza since they have been very shady lately and slowly becoming more bold.

His dad and step mother Emi have been extremely supportive of him, they try and help him train as much as they can. His dad helps by constantly cancelling his quirk and forcing him to fight without it, he even began teaching him how to fight with a knife and gave him one once he was able to knock it out of his dad's hand.

Emi has filled the role of his mom but makes sure to never overstep his bounds, she even tries to always make him and Aizawa smile every chance she gets. The scary part is when she cooks and both him and his dad are sleeping and ignore her... They still have the bruises even after 2 weeks.

___

(4 months later).

After 4 more months of training Izuku finally got up to 15% and his eyes can keep up with the massive amounts of speed, though when he gets up to that level then none of his teachers or even Rumi can keep up with his speed or strength.

As of right now Izuku is shooting through the city at insane speeds, looking like nothing more than a bolt of white and green lightning. He jumped off the side of a building before shooting off and in quick succession kicking a 2 pointer before he did a Delaware Smash and destroying a group of 3 pointers. He then turned around and saw Rumi jump over him and drop kick a 3 pointer destroying it instantly.

"Good job Rumi" said Izuku with a smile.

Rumi smiled "I got 45 points Izuku so you better keep up!".

"Ha I got 62!!".

He then saw anger appear in her face before she shot off looking for more robots in training session.

Izuku chuckled and shot off passing her in a second and could distinctly hear her screaming, he turned a corner and saw a 2 pointer so he raised his hand bringing his pointet finger to his thumb "Delaware Smash!".

Instead of a compressed air blast coming out, black wisps/tendrils shot out of his arm and began destroying everything in his path.

Izuku let out a scream as his quirk got out of control and black wisps kept shooting out flinging him around and destroying anything and everything in his path "stop!".

He tried to regain control and force it to stop but that didn't work, it just kept doing what it wanted as if it had a mind of it's own.

"IZUKU!" Yelled Rumi running towards him since she heard him scream and saw the destruction, along with those black wisps.

"S-stay away I can't control it!!" Yelled Izuku as he was then tugged away while Blackwhip lashed out at her making her jump away to dodge it.

He was then tugged away which made him smash into a building, he tried to make it stop but it wouldn't listen no matter what he did.

"Damnit.. stop.. STOP!!!" He then stopped as his eyes widened before they glazed over.

___

Izuku opened his eyes in a massive black void, he tried to speak but noticed that he couldn't because of a black substance was covering most of his body, mainly his mouth though.

"Where am I? How did I get here... Wait is Rumi ok!?".

"Hello Izuku" said a voice behind him.

Izuku turned and saw a tall lanky man with shoulder length white hair and green eyes.

"I see that you can't talk yet, that means your connection isn't strong enough yet, but then again you are way ahead of any of us until we passed on and we could talk to each other.

Oh right I forgot to introduce myself, I'm Yoichi Shigaraki and I'm the first wielder of this quirk, but I'm also your great great etc grandfather from well over 200 years ago".

Izuku's eyes widened hearing that.

Yoichi stopped for a moment before he turned around "don't worry I'm almost done, just give me a couple more seconds.

It seems my time of talking is almost up, but before I leave. My brother is still alive, he's still out there now we're gaining his strength and most likely building an army of followers to take back your quirk and to rule the world. All of us failed but I believe in you Izuku, you shall be the one to complete this quirk and you will be the one to defeat All For One, once and for all".

Yoichi left and then someone else walked forward, he was a tall well built bald man, he was wearing a black trench coat and had a pair of goggles on his head.

"It seems that Yoichi is done talking to you, not only that but my quirk is the first one you unlocked which is a good thing since it's a grade A quirk, my name is Banjo by the way.

My quirk is called Blackwhip and your using it all wrong, it works off your thoughts and emotions, you think it and the quirk will try and do it, not only that but the angrier you are the more powerful and violent it is. Don't be scared of it, learn to control It and it will never fail you, now get out there and master mine and the 5 other quirks!!".

___

Aizawa ran forward and saw his son still being consumed by strange black wisps that were destroying everything, he was about to activate his quirk but he then saw Izuku suddenly lunge out his arms and the black wisps shot out and anchored themselves into the building.

"M-man t-t-this is hard to control" he said Izuku before the pain in his arms and hands became to much and he fell to the ground painfully "I'm gonna feel that in the morning.

Rumi landed on the ground next to him and he heard wings flapping and saw Ryuko land on the ground and her wings retracted back into her body as she ran up to him.

"Izuku what was that?" Said Rumi helping him up.

"I... I unlocked another quirk..." Said Izuku still trying to wrap his head what Banjo said.

"What do you mean unlocked another quirk? How is that possible?" Said Ryuko.

Izuku then proceeded to explain everything he heard to them along with his dad and teachers, safe to say they were beyond shocked and they all came to the same conclusion. He has to train even harder to master this new quirk.

And so that's what they did after that, they all trained together everyday for the next 6 months which brought Izuku's control to 30% and he mentioned something about visions of a tall beautiful woman with obsidian black hair trying to talk to him.

Rumi and Ryuko weren't happy about that and Izuku wound up imbedded in a wall up to his ankles.

But now they all stood Infront of UA for the entrance exam.

"Are you two ready?" Said Izuku looking at them both.

"Yes" said Rumi with a big grin on her face.

"I am more than well prepared" said Ryuko as she tied her hair into a ponytail before they all walked in for the entrance exam.
