Pairings To Be Decided
No Magic!
Thanks to the incredible writers Son of Caliban to whom I say "REPENT! FOR TOMORROW YOU DIE!" I joke of course, but I am more of a Sanguinis guy myself. I recommend you read his 'From the Joy, Comes the Pain, From the Pain, Comes the Joy.'

Another writer I wish to credit is darkfire1220 and a urge people to read Viridescent. Just want to say thanks for his permission to use some of Quirk ideas.

I own nothing apart from part of this idea…I believe I've credited everyone; if not message me and I'll include in the Footnotes or this dribble dravel

Hailey slammed Shinso against the mat, with more force than necessary as Jiro did the same with Midoriya "Were you thinking, Shinso? Or had you decided that our plan was worth airing to the Hero Course?"

Shinso tapped "1-A's blonde-haired temper tantrum, ran his mouth. Called you a 'dyke' and a 'black-haired useless extra' amongst others that I will not repeat."

Hailey stiffened "I've…heard them all before Shinso. Thankyou, thankyou for standing up for me. But that still doesn't dismiss the fact that you blurted out the loophole that we were planning to exploit in open-secrecy to 'ENTIRE SCHOOL'. If it wasn't for the fact that you have a brain and the capacity to ask the right questions, I'd be concerned that I was training a moron."

Jiro chuckled, one that made Hailey go weak at the knees "Speaking of morons, can we trade? Because as scrawny as Midoriya is, hitting him is like hitting a brick-wall."

Hailey cocked her head, disengaged from Shinso, popped to her feet. Shinso mimicked her, they bowed to each other as the gym doors opened. It was Aizawa, Mic and surprisingly Midnight "Hailey, Jiro, Shinso and Midoriya?" Questioned the Erasure Hero.

"Aizawa-sensei, Jiro-san brought me here and told me that Hailey-san was going to 'help me control my quirk'." Eraserhead grinned.

"Midoriya, my daughter is one of the best at helping people control their quirks. Also, UA is known for using whatever designs necessary to make the best heroes. What was your plan for Togata? You made that when you were twelve."

Hailey blushed "I, asked Uncle Loader for leftover pieces of metal, wood and old tools. Then Uncles Snipe and 'Plasm taught me to throw said objects and showed me the film 'Dodgeball'."

Midoriya paled, he knew that film "Dodge a wrench, dodge a ball?"

Hailey grinned, an identical smile to Aizawa. "You, you're definitely the Erasure's Daughter." Midoriya stammered.

Hailey grinned "Thanks. Midoriya, when my dad's here please call me by my first name and dad by his hero name…Now, Jiro…you're about to cause him to cramp up."

Jiro got off Midoriya; whom she had in a choke and arm-hold. Midoriya stood up, shaking off his previous injuries and turned to face Hailey. Hailey looked absolutely relaxed in what was to come, Izuku knew that he could read people pretty well and thought he had his new opponents measure. "Ready, Midoriya?"

Midoriya nodded and as he was about to open his mouth, his vision filled with stars; the breath driven from his lungs, his entire body temporarily paralysed and he collapsed to his knees and into the foetal position. "Did you really have to do that?"

"Shinso, I did this to you as well…" Shinso turned faintly grey at that.

"Don't remind me. I now have to contend with your fathers boot in my gut and across my ribs now; but I'm content." Midoriya had gotten to his feet.

"Villains don't wait for people to be ready…"

Hailey giggled slightly "Jiro-chan, you never told me he was a quick learner! Boo, this is going to be boring." She turned to the green-haired glass cannon.

"Alright, welcome to Fuckedville; population you and Shinso. Here at Fuckedville; I am Judge, Jury and Executioner favouring execution without the Judge and Jury. I've been told Midoriya; that your quirk 'superpower' which is an absolutely stupid name by the way, trashes your body. The body can take so many breaks before it can't sustain it. You've only broken your fingers and right arm correct?" Midoriya nodded and dodge a groin height kick.

"Now, I'm going to kick you around until you get a semblance of control over your quirk. How do you picture your quirk at this point in time?"

"An egg…in the microwave."

Everyone stopped, including the Teachers. Hailey then took Midoriya's leg out, he hit the floor and she had one hand flat; resting on his solar plexus and the other near his temple. "Who, What, When, Why and How did your Quirk manifest? Furthermore, who botched your training? I'd advise you tell me the truth."

Midoriya gulped "It's complicated and it's not just my Quirk…"

Eraserhead looked extremely tired "Who else Problem Child? Hailey, he can't talk if he can't breathe; I knew leaving you with Crawler, Pop-Step and Knuckleduster for three weeks was a bad idea."

Hailey lessened the pressure "You're not going to asphyxiate anytime soon, you drive my parents bonkers Izuku…I'm not losing another hellraiser like you anytime soon. Although if you paint yourself white, stick fucking pins in your head and wear all black and declare yourself the 'Black Pope of Hell' and 'Hell Priest'…it won't be pretty."

"Hailey, those films are disgusting." Jiro murmured looking slightly pale.

"But hilariously bad…You didn't mind them did you?"

"Only because I had you as a cushion." Jiro retorted.

Hailey, bit her tongue. What she wanted to say would have most definitely knocked out Aunt Kayama and quite possibly Shinso as well. As for Midoriya, his mind would have worked it out and would have been rendered a wreck.

However, Midoriya had sent out a text with Eraserheads permission and an extremely emaciated man, with hair that resembled someone from Def Leppard positively slouched into the room. "Young Midoriya, Aizawa, everyone…Young Midoriya, I got your message."

Midoriya looked at him "Aizawa Hailey, offered to help train my quirk. She suspects something due to compatibility issues with it." The strangers eyes widened and then narrowed.

"I…do not…"

"Pardon the interruption, who are you? How do you know Midoriya?" Hailey stated.

The skinny man looked at Aizawa, who nodded reluctantly "Please keep everything you're about to see to yourselves." The teens nodded.

There was a puff of smoke and where the skinny man stood, was now All Might "I AM HERE TO EXPLAIN!"

"All Might…is teaching here?" Shinso questioned. He'd seen All Might previously in the gym before but hadn't clicked. He'd have thought All Might was merely having a look around his Alma Mata or had been providing a speech to the Hero Course.

"Aye. This is the part I need you to keep a secret. My Quirk, can be passed on. It is the equivalent of a torch or an allotment, one person created it and the next cultivates it and so on. I, inherited the Quirk from my Master who died against the man who created it; for my Quirk is called One For All." All Might explained.

"Shot in the dark, the man who killed your master called All For One? If so, Alexandre Dumas descendants should be paid handsomely." Hailey commented, getting everyones attention.

"Alexandre Dumas?"

"French writer. Wrote the Three Musketeers? Un pour tous et tous pour un? All for one and one for all…"

Eraserhead chuckled at the reference "Continue, All Might."

All Might nodded "AFO and I fought. I believe he's dead but he has ended my career. Everyday, the amount of time I have to maintain my alternate form decreases; I needed to find a successor and thus Young Midoriya. However, we had ten months to prepare him for the entrance exams."

Eraserheads eyes widened "He went into the exam, having never used his quirk before! How irresponsible are you?" All Might cowered in front of the griselled Underground Hero.

"Do I even want to know how you told him to use the quirk? What makes up OFA, the base quirks?" Mic questioned.

"You have to feel in your heart, and cry 'SMASH!'" Izuku said catching everyone off guard. They'd forgotten that he was there.

Everyone stilled "That's a new one…Midoriya, you're a quirk enthusiast what makes OFA, OFA."

"All Might said there was a transfer quirk and a stockpile quirk."

Hailey stopped "All Might-sensei, stockpile quirks are unpredictable…especially if they're as old as this one. No bloody wonder, Izuku's pureed his skeleton after every single bloody one; he's got a ninth generation QMD, Quirk of Mass Destruction that has poorly adjusted to his body; then you freely admit that you rushed the training to prepare him for this. You should have allowed him into the General Education or Support Course then had daddy help train him. I understand that you've got a façade to put up, you're many things All Might but your teaching…"

"Requires drastic improvement. I understand." The emaciated hero rasped with, thankfully, very little blood erupting from his mouth.

"Hailey, you've got just under two weeks to get Midoriya a semblance of control."

Hailey smirked "Like I said Midoriya, welcome to Fuckedville. We're wasting time."

(Two Weeks)

40 Additional Hours, 40 Additional Hours into an already rammed day was all Midoriya could honestly remember. These last two weeks, felt more like a form of torture more than anything; it was hard to hide looking like a living bruise.

His mother had found out and after nearly flooding the apartment with her tears; she'd found the Aizawa home address. Needless to say, Midoriya Inko was one extremely overly protective mother.

(Flashback Saturday week one)

Inko and Izuku pulled up outside the Aizawa residence coincidentally as Hailey made it back from her run. Izuku got out the car "Morning."

"Midoriya, how's the head?"

"Pretty good. Look, my mother…" Hailey's breathing was forcibly returned to normal.

"Wants to know why her son is looking like a living bruise…I get it, I think. Does…she know, about…the thing?" Izuku hung his head. Hailey groaned.

"Midoriya…you…naïve and slightly selfish shellfish."

Just then Inko chose to get out of the car, Hailey stepped backwards enough to just be on her families property "Are you the one who's been turning my Izuku into a living bruise for the past week? If so, why?"

"Izuku came to me for help with his quirk. I'm training him in regards to how he was trained prior the entrance exam; brutally, hands on and repetitively."

Inko's eyes hardened slightly "What sort of quirk, does Izuku have that requires such blatant abuse to the point of it being called bullying?"

Hailey sighed and, in that moment, she looked like an exact replica of Aizawa. Her hair began to levitate as her eyes took on a distinctively red tone "Don't activate your quirk. I've erased it. Mrs. Midoriya, I'm not sure if you've realised that as heroes; we could die if we're not prepared, your son is definitely not ready for this. However, he does possess and one of the scariest mind-sets that my dad and father have ever seen. In regards to his status as 'living bruise', would rather him alive looking a living bruise or potentially permanently paralysed or unable to use his arms?"

Inko stopped "What…" Was all she could say.

"Your son has a quirk that is ON PAR, or if not SUCCEEDS ALL-MIGHT in pure strength."

Inko, knew of All Mights incredible physique…who didn't and then looked at her son. Everything quickly fell into place "He's a living bruise to protect himself? How bad was it?"

Hailey's hair flattened "How bad was it? It's bad…that his quirk OBLITERATES his body whenever he uses it; at this point in time it is 'all or nothing'."

Inko stared dumbfounded at her son "Quirks mutate, some in identifiable manners and some are just plain 'WTF', your son's quirk is 'WTF'."

Inko stood there and nodded "If this is the only way."

"This is the way. I appreciate your concern for Midoriya but if he wants to be a hero, he needs to control his quirk."

(End Flashback)

It had finally arrived; the two weeks of training was done. Midoriya had managed to control an entire 3% of his quirk with no difficulties, and sporadically up to 5%.

All the classes got changed into their gym kits and headed out in neat and precise groups as Present Mic yelled "Can I get a PLUS ULTRA!"
