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

Friday dawned and after the morning ritual beating of Shinso; but this time, in the spars Shinso managed to pull a win over Hailey. He'd asked her a question about maths and activated his Quirk to get her to submit. "It took you long enough."

"You meant to tell me, I could have used my Quirk earlier?"

"No shit; but at that point in time it wouldn't have benefitted you." Hailey replied, leaving the shower in her undergarments. She was fine with Shinso observing; because secretly it made her feel good. As they got dressed in their gym gear; they'd submitted their hero costumes but unless they were approved onto the Hero course it didn't really matter.

Shinso cocked his head, the training he was doing had been doing wonders for him. Whereas before he was naturally trim and slender; now he was showing definitive muscle in his arms, it was as if cloth-fighting required usage of arms. "Your Quirk, brainwashing, has no immediate combat-effectiveness; much like mine and dad's. So, we had to learn how to fight to make our Quirks work effectively in combat."

"So, do I. I see." He grinned slightly; there were times when he thought was the training worth it.

"Now you're remembering the times, you wanted to throw it in. I don't blame you for wanting that, no-one does. The fact you've stuck with it and no we're on a probationary chance to do hero exercises."

Shinso grinned "We need to go beyond, Plus Ultra."

Hailey nodded "Plus Ultra; nice saying. I prefer Excelsior!"

"What's that mean?"

Hailey stopped "You…don't know the meaning of Excelsior?"

Shinso shook his head "Not really."

"I'll correct that. There's a lot of things, I need to correct you on. Because Excelsior, that word meaning 'Even Higher' or 'Ever Upwards' it is rumoured to be the heart of Heroics."

Shinso was taken aback at the sudden fervour in her tone. "You ready?"

Shinso nodded, he was wearing the school gym uniform and his sturdiest pair of shoes as he looked Hailey. Similarly, to him, she was wearing the gym uniform but on her feet were a pair of military style combat boots. "Yup. Dad's got the rest of our kit."

They headed up to the staffroom, knocked and found Mic sitting at his desk "Hey listeners."

"Papa, you activate your quirk…Did dad leave…" Mic nodded as murmured in English 'When did my cute innocent daughter become so sassy and grouchy.'

"Dealing with a cockatoo, peacock like you papa…Love you." She replied as the duo departed the staffroom. The bag Hailey had, contained three sets of binding cloth; one for over the shoulders for Shinso, two for wrist and arm guards for Hailey and various other miscellaneous objects.

"You two ready?" Shinso turned to find Aizawa waiting for them.

"You're wearing those?"

"Closest thing to the boots in my Hero Costume. If I'm doing this, then I'm making sure my feet are protected."

Aizawa chuckled beneath his capture cloth and handed, Hailey, a pair of black goggles "Like father, like daughter."

Both Aizawa's looked at Shinso with a similar dumbstruck expression, causing the purple haired teen to catch the picture on camera. "Comedic gold."

"I will get you for that Hitoshi." Aizawa growled.

"I know you will, sensei. But for now; I will naively and cheerfully celebrate this temporary victory. We can't win them all, but Heroes must go on." Shinso retorted.

"Go on and going beyond." Aizawa retorted approvingly.

"EXCELSIOR!" Cheered Hailey.

"Even higher and ever upwards."
"I know. When do we go?"

"Now."

Aizawa led the General Ed students towards 1-A "Miss Aizawa, Mr. Shinso; I trust you have the assignments for today?" Ectoplasm questioned.

"I'll send them the assignments sir, as is my duty as class rep." Called Agoyamato Tsutsutaka, a tall student with blue hair and a distinctively large chin.

"Our thanks, Class Representative."

"You show those Class 1-A Heroes that Gen-Ed want to be Heroes too!"

Hailey's eyes narrowed "We will. I have a plan, depending on how this turns out, I'll bring the rest of you in."

They were the last to arrive "How dare you! Just because you're…"

"We were dealing with matters pertaining our education should this exercise not come to satisfactory resolution." Hailey retorted putting the armoured teen in his place.

"My…"

"Save it. You're just wasting air and our good nature." Shinso finished. The collective class of 1-A, winced at the put down.

Jiro grinned "Hey, Shinso. Hey you." The rock-star looking Hero said as she hugged Shinso and pulled Hailey into a longer one.

"Hey yourself…Damn, you actually got Stereo Boots? That's…awesome." Jiro grabbed Hailey and like on their day-trips in Middle School grabbed a seat together with Shinso behind them. Shinso quickly ended up next to a blonde teen with name of Kaminari Denki.

"What's your Quirk? How come your in General Education?" These questions came out of the left for Hailey; she had been happy listening to Jiro's headphones.

She turned around and nearly headbutted a pink and fluffy "Ashido, back up. Hailey…calm down, it's only Ashido…"

"The Corrosive One?" Mina pouted at that.

Jiro sighed "Ashido, I've known Hailey for years. I've known you lot, a few weeks now? Anyway, I only had brief descriptions of you."

"Honestly; so far she's not been wrong." Hailey commented.

"My Quirk: Rationality…Nothing useful initially but with a bit of brainwork and cardio, you could become a decent Hero…As for General Education; think about it."

"That was a little bit strong, Kero." Croaked Tsuyu.

"I have…expectations, shall we say and they're logical and rational explanations on what I would like to see. However, the annoying part is I…have…no filter on what I say. I like being honest but…"

"I say what's on my mind, Kero. I think you're concealing something from us, Kero."

Hailey grinned, Tsuyu was sharp! Kyoka hadn't told her of this! "You know how Quirks and Genetics have parallels in research data…It's not what was said, but rather how it was phrased."

Aizawa smirked. His class should have made the connection, the actual truth was stranger than fiction, he watched his daughter and grinned. "I understand Hailey…You have my blessing, Kyoka…is good for you." He wasn't unaware of her flaws, thankfully she found Kyoka; like Hizashi had found him.

Kyoka was right! Hailey wanted to kiss her right now, but things were weird between them! But as of right now, they were able to put on façade; that everything was good. Hailey quickly found herself bonding with the other girls and a few of the guys in Class 1-A.

Shinso, similarly found a friend in Denki Kaminari. The pair had bonded over strangely literature and Jiro. Considering what he'd heard third-hand from Hailey; who'd heard it from Jiro. "Jiro and Aizawa…I'll make a killing." "Hey, Shinso…oh…You like Jiro? Who's she talking to?"

"That's Aizawa Hailey. She's known Jiro for a while. I know Jiro was because as Hailey put it 'I need a punch bag that punches back.' Hailey taught me, everything I know…"

Denki gulped slightly. He may be slightly disinterested in theoretical heroics; he did know the cloth that Shinso adorned his shoulders. "You know how to use that?"

"Little."

"You know if…"

"Nope. Don't know, don't care, don't need the additional bruising…I get enough of that as it is." Shinso replied getting a pout from the Blonde-haired boy.

"Speaking of who's your favourite Hero? What sort of Hero, you wanna specialise in?"

Shinso's eyes widened slightly "Unsure…Rescue or even Liase with Police in terms of suicide."

"That's manly, very manly…" Any other comment was drowned out as the words 'edgy' and 'emo' were used to describe the potential followers of Bakugo.

"You fucking said what, you Frog-face? At least those who'll follow me won't be snotty, defenceless brats and useless losers like Deku." Snarled Bakugo.

"Okay, Stress Bitch, why do you want to be a hero? What makes you want to be a hero?" Hailey asked, turning to lock eyes with the animalistic member of Class 1-A. Even the Beast Quirked User in 1-B was politer than this guy!

"I want to be a hero, because I've never lost at anything. With my Quirk, I can never lose. I will become greater than All Might. Don't you extras fucking forget that, especially you two extra-shitty extras from General Education."

Hailey winced "Don't rise to the bait…Don't rise to the bait, break him yourself…Make him feel powerless." "What's with the murder-boner to Deku? Is there anyone, here called Deku? If so I'm sorry about your name."

"Me! My names Midoriya Izuku, Kaachan calls me Deku." Midoriya said.

"What happened to your costume? What was it? Sorry, nice to meet you. Aizawa Hailey." Hailey replied, noting that the Greenette Broccoli Hair and the Sports Costume.

"Training accident, yesterday. Got a new one submitted, yesterday but it's gonna be available Saturday or Monday. As for what it was, it was a green jumpsuit with a green full on facemask resembling 'All Might's Smile'…I thought I'd failed the entrance exam and…I'd rather not talk about it." Midoriya stuttered, by the end of his statement he'd gotten even worse until he finished with his words almost falling out of his mouth.

Hailey winced "I can only imagine. What is your Quirk?"

"Is it similar to Aizawa-sensei? Given your surnames?"

"Not really…My Quirk…it's easier to see than to explain; but the side-effect requires me to be more logical and tactile in planning to use it effectively."

Midoriya nodded "Mine…mine's an enhancement quirk, but I can't use it effectively."

"How? I thought Quirks materialised when you're four. Although, I've records in Europe that Quirks can manifest later; one case was for a ten-year-old, which gave her a quirk similar to old fantasy Werewolves."

"Mine only came in recently. It needed my body to be in a certain shape, to manifest without…disabling me or…blowing my limbs off."

The class collectively winced, Aizawa looked at him "Midoriya…that…would have been useful to know. After school and on Saturdays until Miss. Aizawa and Recovery Girl say otherwise, you're the 'striking post'." Midoriya gulped as Hailey, Jiro and Shinso all grinned.

"Don't worry, if you managed to get your Quirk unlocked you can do this."

Just then the bus stopped and everyone disembarked outside of a unique building. "Everyone in an orderly fashion please!" Boomed Iida and following him the twenty-two students entered the building.

"Welcome, to the Unforeseen Simulations Joint. Also known as the USJ."

"Sharing the initials of Universal Studio Japan." Came the collective thoughts of the class. As they entered everyone's jaws collectively hit the floor. The USJ was gigantic; there was a massive central plaza and six indescribable exercise zones such as: Ruins, Landslide, Mountains, Conflagration, Floods and Downpours.

"This building has been a pet project of mine since I've started working here. It is designed to show you; alternative ways to utilise your Quirk outside of combat scenarios." Thirteen explained before demonstrating their Quirk of Blackhole.

Hailey had pulled out her phone to check the time, and saw she had no signal. She entered a secret programme in her phone that allowed her to connect a secure hard-line internet in UA; a Mascot of UA did have a perk. There was still no signal "Kyo, check your phone…I've not got signal."

Kyoka turned sharply, causing Yaoyorozu to turn "No phones out in Class!" She began to say but when she saw that both Jiro and Hailey had no signal; she checked hers as well. "I thought you said it was impossible to not get a signal at UA?" Jiro said.

"I was never actually brought here…Thirteen, never really babysat me. Plus, something about Rescue Heroes and Occupational Hazards are bad for a baby's health…I never said it was impossible, I said 'You're more likely to be a millionaire than the schools systems failing', you attributed this to 'impossible'…This is either a freak occurrence or…"

"A trap!" Eraserhead finished. All Might had used all his time up for the day! Now his daughter, who he was trying to be professionally distanced from; was here. This was one of the things he hated about being a parent and a hero!

"Thirteen defend the Students. Students, get out of here. Use your Quirks as you see fit." With that Eraserhead launched himself down the stairs at the oncoming Villains. Only for the roiling, writhing, gaseous Quirk wielder to take on a humanoid shape in front of Eraserhead, and re-direct him to the students.

The mass of smoke then joined them atop the stairs, took on a humanoid form and a group of villains and a monstrosity emerged from the smoke. "Good Day, Sorry to interrupt, we are the League of Villains. We're here on business with All Might."

"Kurogiri, since All Might is not here, perhaps killing some of the youth will coax him out of hiding." One of the Villains with covered in hands muttered as he itched his neck.

"Eraserhead…what do we do?" Called Iida.

"It's simple, we stand and we fight." Aizawa retorted as he rushed the Villains.

Kurogiri convulsed and grabbed Shigaraki and the Monster and vanished. Eraserhead, found himself in the opening group of twenty rent-a-thugs. As the Homeroom Teacher dived into the fray, the Twenty-two students fragmented.

Bakugo, Kirishima and surprisingly Sato charged forwards; with the physical intention of assisting their teacher. Unfortunately for them; Bakugo soared over them. Shinso looked to Hailey, who shook her head; this was a Class 1-A matter. They would let Class 1-A sort themselves out.

Jiro made her way over, her earjacks pushed together "How are you holding?"

"Okay, terrified. I want to help but…"

Jiro stopped her "Don't let us, Class 1-A, hold your instincts back Hailey…We're all here, right now, we need to get out of here alive."

Hailey nodded and pulled her gown goggles up. "Shinso, with me. We need to get the doors open, then our fastest can run back to the school to get the Teachers."

The initial villains had been dispatched and Eraserhead charged after Bakugo. Hailey only realised Ojiro was next to her as purple smoke descended over them.
