"Man, this place is so big! 1-A...1-A..." Izuku ran through the halls of U.A. High as his first day at the school finally arrived. He finally arrived at the door for his classroom. "Aw man, I hope I'm not in the same classroom as the scary people..." Izuku immediately thought of Katsuki and the boy from the entrance exam as he began to slide open the door.

"Take your feet of the desk!"

"Huh?"

"Don't you think that's disrespectful to the U.A. upperclassmen and the people who made the desk?" Just. His. Luck. BOTH of them were here, and the blue haired boy was already beginning to get into with Katsuki who sat with his leg on the desk.

"Ha! Nope! What junior high did you even go to, you side character?" Katsuki asked with his usual smug grin.

"I attended Somei Private Academy. My name is Tenya Iida." Tenya said introducing himself to Katsuki.

"Somei? So you're some kind of fucking elite, aren't you? I'm gonna have fun stomping you into the ground." Katsuki said intimidating the taller boy.

"Stomp me into the dirt? And you actually want to be a hero?" Tenya asked in pure horror before both boys noticed Izuku standing in the doorway. Then the whole class turned their attention to him, causing the usually timid boy to jump slightly. "Good morning! I'm from So-"

"It's alright, I heard." Izuku said raising his hand to the boy as he walked over to him. "I'm Midoriya. Nice to meet you, Iida."

"Midoriya, you realized there was something more to that practical exam, didn't you?" Tenya said gritting his teeth. "And I didn't...I hate to admit it but you're better than me."

'Sorry. I actually didn't realize anything.' Izuku thought before feeling a tap on his shoulder. He turned around to see Hayato standing behind him with a banana in his hand. "H-Hayato?!"

"You!"

"I made it too, buddy. All Might didn't tell you?" Hayato said finishing up his fruit. Izuku jumped him for a hug making his best friend wince in pain. "Izuku, buddy, I'm still sore in some places."

"Oh, I'm so sorry!" Izuku said letting him go and noticing the slight limp Hayato had.

"Oh, you're the loud guy from the test." Hayato said walking into the classroom and noticing Tenya standing nearby.

"I'm from Somei Private Academy, my name is Tenya Iida."

"Hayato Kiryuu, sorry for the harsh words back then. Just don't like when people pick on my best friend." Hayato said before limping over to his seat.

"Oh, that curly hair! You're the boy from the exam!" Izuku turned around to see that Ochaco had just walked in, happy to see him. "That punch you did was awesome!"

"I-I mean it was nothing! Th-Th-Thank you for trying to split your points with me!" Izuku yelled covering his now red face with his arms before quickly bowing to the girl in front of him.

"How did you know about that?" Ochaco asked as it hit her what Izuku was talking about.

"Oh, uh-"

"If you're here to make friends, you're in the wrong place." The four standing at the front of the class looked behind Ochaco and Izuku to see that, currently in a yellow sleeping bag on the ground, a pale man with long black hair laid looking at them. Ochaco, Izuku, and Iida all froze from shock while Hayato made his way to his seat. "Eight seconds for you to be quiet, you need to work on that. This is the hero course, time is limited and kids these days are so irrational." The man said as he unzipped his sleeping back to stand up.

'A teacher? So that means he's a pro hero too. Except I've never seen anyone as worn out as him.' Izuku thought as he studied the man from head to toe, from his all black clothing to the odd scarf around his neck.

"I'm your homeroom teacher, Shota Aizawa. Nice to meet you all." Aizawa said introducing himself to his class. The entire class jumped slightly as they were all in the dark as to who their teacher was going to be. He lifted up his sleeping bag and reached into it, pulling out a blue tracksuit with white markings becoming a "U" around the collar and an "A" on the waist. "It's kind of sudden, but put this on and head out to the field."

"A Quirk Assessment Test?!" Was the general reaction from the class as they all stood across from their teacher, all dressed in the tracksuit he had shown them before.

"I hope none of you were expecting anything traditional from your first day, the selling point of this school is how unrestricted we can be with our methods. That's how we teach and that's how you're all going to learn for the next three years. Besides, you kids have been doing this since Junior High, right?" Aizawa said taking out a phone to show eight different exercises. "All those physical exams where you were banned from using your Quirks, we're gonna change it up a bit. Bakugo, you finished at the top of the practical exam, right?" Aizawa asked getting Katsuki's attention. "In Junior High, what was your best result for the softball throw?"

"67 meters." Katsuki said as he crossed his arms, trying to remember the best he could.

"Then, try doing it with your Quirk." Aizawa said taking out a softball from his pocket and throwing it over to the boy, who caught it with one hand and walked over to a shotput ring behind his teacher. "Do whatever you want, just stay in the circle. Now hurry up, and you better give it everything you've got."

"Alright then..." Katsuki said stretching his arms. He looked forward and entered a pitching position. "DIE!" Katsuki pulled back the best he could and threw the ball, boosting it with an explosion.

"...die?" Izuku asked himself quietly as his expression deadpanned, watching the ball skyrocket into the distance.

"Always know your maximum as a starting point. That's the most rational way to form the foundation of a hero." Aizawa said as he turned to face his class, showing Katsuki's score as 705.2 meters. The whole class clapped from amazement as Katsuki walked back to them, with a victorious smile on his face.

"705 meters? Seriously?" A boy with orange-blond hair with a black streak across said as he took a step back.

"This looks so fun!" A pink girl with pink hair and horns yelled as she happily jumped from excitement.

"This looks fun? You have three years here, are you sure you're gonna keep that attitude the entire time?" Aizawa asked making the class tense up, quickly draining their excitement from them. "Alright then, whoever comes in last place after all eight tests will be judged to have no potential to be a hero. And as a result, the punishment will be immediate expulsion." The entire class screamed from shock while Hayato closed his eyes, feeling a sharp pain in his legs. "We're free to do whatever the hell we want with you kids. So welcome to U.A.'s hero course."

"This might be a little difficult for me." Hayato said as he reached into his pockets to take out a pair of pills and threw them into his mouth.

"For you? Hayato, I can only use One for All at zero or a hundred percent!" Izuku whispered into his best friend's ear. Hayato sighed and elbowed Izuku hard into his stomach area, immediately knocking the wind out of him.

"Mr. Aizawa, Izuku's not feeling so well so I'm gonna take him to the bathroom!" Hayato said grabbing Izuku while their teacher just waved them off. The two quickly made their way out of sight from the class and Hayato pushed Izuku against the wall. "What the hell is the matter with you?"

"With me?! You just hit me in the stoma-" Izuku yelled as he took in a deep breath. Hayato covered Izuku's mouth to keep him from yelling further, not noticing their blond mentor was hiding from them as well: watching them in the distance.

"Izuku, we made it this far. Are you going to give up on me now because you're worried about getting hurt?" Hayato asked making Izuku shake his head. "I brought painkillers because I didn't want to let you down. We have THREE years here, if you're gonna chicken out day one then you might as well grab one of your hairs and shove that Quirk back down All Might's throat." He removed his hand from his best friend's mouth. "You're my best friend and All Might chose you as his successor. You're the smart one out of the two of us, figure it out if you don't wanna go home on a stretcher." Hayato said tapping Izuku's forehead. He began walking back while Izuku looked at his right hand.

'How do I manage to do this?' Izuku asked himself before following Hayato back to the class.

"Alright so the first test is the 50-meter dash. Iida and Kiryuu, to the line." Aizawa said as the two re-joined the group. Tenya and Hayato nodded at each other and walked over to a track and went into the starting positions.

"Ready? Get set..." Hayato chuckled and activated his quirk as a camera on a tripod at the end of the track counted the two down. "Go!" Tenya and Hayato took off, with the former running as fast as he could in that short distance: reaching the end almost immediately. But what shocked him the most was that when he crossed, Hayato was already standing in front of him with a victorious smile.

"What?!"

"1.15 seconds. 3.04 seconds." The camera announced as the class looked at Hayato in shock. Hayato held up a peace sign to the group and began walking over, leaving Tenya staring at him in pure disbelief.

"Impossible..." A spiky red haired boy said as Hayato walked past him and to Izuku's side.

'I can only go third gear for fifty meters...but he was on a completely different level.' Tenya thought to himself as he walked back into the group, letting the exhaust ports on his calves cool down.

"They were in their elements. Next, Bakugo and Midoriya." Aizawa announced making Katsuki and Izuku walk over to the track and ready themselves.

"Ready? Get set..." Izuku gulped as he could feel the bloodlust emanating from Katsuki. "Go!" Both boys took off, with Katsuki holding his hands back and Izuku running as fast as he could.

"Let's see how you bastards like my Explosive Speed!" Explosions began firing from Katsuki's hand, propelling him into the air and forward, crossing the line as the camera recorded his time.

"4.13 seconds." Then Izuku crossed, beginning to breathe heavily. "7.02 seconds."

"When I use both of my hands, the force disperses...but Deku could be screwed..." Katsuki said as he looked at the smoke coming from his palms before looking at the already exhausted Izuku. He shook his head, letting out a growl while Hayato chuckled.

"Someone's worried about you." Hayato said quietly to himself before placing a handful of raisins in his mouth while their teacher called over the next pair to run.

"If I may ask, why do you keep food in your pockets?" Hayato turned around mid-chew, to see a girl with long black haired tied into a spiky ponytail looking at him.

"Oh, my raisins? They're my energy snacks." Hayato quickly gulped down what he had in his mouth and took out the small red box that held his snacks in from his pocket.

"Energy snacks?" The girl asked confused at the box of raisins being held in front of her.

"I gotta refuel, we have a lot of tests coming up and I can't risk losing power during any of them." Hayato explained putting the box away.

"Yaoyorozu, Uraraka. Come on, you're up." Aizawa said making the girl nod and walk over to the track.

"You talked to a girl!" Izuku whisper-yelled to Hayato, who looked at him confused by his excitement.

"Izuku, I can handle talking to one. Just keeping the conversation is what's tough, especially with one as pretty as her." Hayato said putting the box away in his pocket.

Following the 50-meter dash, the class continued with the next three exams: grip strength, long jump, and repeated side steps. And currently both Hayato and Katsuki were confident in their abilities as they kept scoring among the highest in the current exams. But the one concerning the two, even if Katsuki could never admit it, was Izuku. Restricted by his fear of hurting himself or using too much power with One for All, Izuku currently held one of the lowest scores, only a completely invisible girl was doing worse than him at the moment. But he knew that the fifth test, the Softball throw, was his saving grace. If he could score high enough on this: he would be safe from the expulsion punishment. Even with the long-distance run, sit-ups, or seated toe touch: he knew that a test involving strength was perfect for him and One for All.

"Uraraka, throw." Ochaco nodded and walked up to where Katsuki had thrown the ball from earlier, and threw the ball watching it climb higher and higher into the air. Aizawa nodded and showed the screen on his phone, revealing the score was reading "infinity" for the girl.

"Infinity?!"

"Whoa, that's awesome!" Ochaco blushed and nodded sheepishly at the praises from her classmates.

"Midoriya, go." Izuku nodded and walked up, grabbing the Softball and holding it in both of his hands.

'It's now or never. I came too far to let All Might, Hayato, and Mom down.' Izuku readied himself and took a deep breath, activating One for All.

"It doesn't look good for Midoriya if he continues the way he has." Tenya said earning a worried nod from Ochaco, making Katsuki chuckle.

"Of course not, he's a Quirkless loser, you know?" Katsuki said making Hayato grit his teeth.

"Quirkless?! You mean you don't know what he did during the entrance exam?" Tenya asked confusing the boy.

"Huh?"

'It's about time, huh?' Aizawa looked at Izuku, grabbing his scarf as the boy closed his eyes.

'I won't let you down, I'll become a hero.' Izuku's arm began to glow as the power of One for All surged through it. He reeled his arm back as he remembered when All Might chose him to be his successor, when his mother congratulated him for being accepted to U.A, and when Hayato had met him in the playground all those years ago. But when he threw the ball, he was shocked to see it land only meters away from him. "B-But...I swore I activated it."

"I erased your Quirk, that's why." Izuku turned to his side to see Aizawa, now the complete opposite of how he looked before. His hair flowing upwards, his eyes glowing red, his scarf was now flowing up and spread out more, and under the scarf rested a pair of gold goggles around his neck. "Damn that test, it's clearly not rational enough when even a brat like you got accepted.

"You erased my Quirk?" Izuku asked himself quietly before it all came together for him once he laid eyes on the goggles. "You can erase people's Quirks just by looking at them, I know who you are. The Erasure Hero: Eraser Head!"

"Eraser? Never heard of him."

"He's an underground hero, he tends to avoid the spotlight compared to other heroes because he thinks it gets in the way." Hayato said earning the attention of his classmates.

"From what I saw, kid, you can't control that Quirk of yours even if your life depended on it." Aizawa said as he walked over to the boy. "You want to break everything and have someone else save you again, don't you?"

"N-No sir, that's not what I-" Izuku was cut off by Aizawa's scarf extending wrapping around him and pulling him closer.

"Whatever your intention, I'm saying that's what others around you will be forced to do." Aizawa said keeping his glowing eyes focused on the boy. "It doesn't matter if you're as courageous as they come and the most selfless hero out there: you'll be utterly useless if you become a ragdoll after saving only one person. Izuku Midoriya, you can't become a hero with that power of yours, you'll only end up being a liability."

"Um, Mr. Aizawa?" Aizawa turned his head hearing Hayato call his name. "I've known about his Quirk for a long time, if I can: I'd like to have a moment with him."

"Do whatever you want, just make it quick." Aizawa said as his scarf and hair went back to normal and his eyes stopped glowing. Hayato rushed over to Izuku's side and pulled him away. 'But whatever you do, that kid is a lost cause. He has no potential whatsoever.'

"What's the matter?" Hayato asked putting his hands on Izuku's shoulders.

"Mr. Aizawa's right, I can't control this power. If I try to go 100%, then he's just gonna erase my Quirk again if my arm doesn't shatter again." Izuku explained making Hayato sigh. "I keep visualizing what All Might told me and it just doesn't work." Izuku sighed while Hayato crossed his arms and raised an eyebrow.

"What did All Might say?"

"He said to remember the feeling I had when I activated it for the first time, like an egg in a microwave and trying to keep it from exploding."

"And when was this?" Izuku tensed up remembering that after he had been accepted: he had met All Might at Dagoba Beach to discuss being his successor and controlling One for All...the only problem was that the meeting was supposed to be a secret and Hayato had no clue. "Well, Izuku?"

"It was before school started, but I just can't seem to control it no matter how much I try. He said to remember the feeling and that it's the secret to controlling this awesome power." Izuku explained making Hayato sigh.

"But Izuku, remember that you and All Might are two different kinds of people. How he controls One for All is different because he's been with it for decades, you've only had it for a little over a month." Hayato said placing his hands on his sides. "When you first activated it, what happened?"

"Well I felt like this like bzzt or woosh feeling and-" Izuku was stopped by Hayato raising his right hand to stop him.

"Not what you FELT, what HAPPENED."

"Well, I put all the force I had into my legs to jump into the air. And then I put everything I had into my arm to punch the villain, and next thing I knew I was falling with all three broken." Izuku explained making Hayato nod.

"You put everything you had into your legs and they broke. Then you put everything into your arm and it broke. You see the problem?" Hayato said earning a nod from his best friend. "You're too impulsive, you haven't had the kind of practice to put that kind of force on your body."

"But I don't have any other way to control it."

"Alright, then let's see it like this. Your body is a fighter jet and it shoots the most destructive and powerful missiles. The triggers to fire them are extremely sensitive so: you can't slam your finger on it, otherwise you'll fire everything you've got when you don't have to, and you can't press it too softly, otherwise nothing'll fire. Forget controlling it with your feelings. Control it with what you have up here." Hayato said poking the side of Izuku's head. "Once the pilot up here knows what it's doing, then you can leave it to the guy down here." Hayato moved his finger from the side of Izuku's head and down to where his heart was located.

"But All Might-"

"Izuku! You're not All Might! Don't force yourself to be like All Might!" Hayato whisper-yelled as he pulled his best friend closer by the collar. "The student isn't the teacher, so don't try acting like him." Hayato let him go and began making his way back to the group.

"Don't force myself to be like All Might and use my brain?" Izuku asked himself as he picked up the Softball.

"Whenever you're ready, Midoriya. You have two more turns." Aizawa said making Izuku nod and ready himself to throw the ball again. He reeled back and threw the ball, trying to push the power of One for All into his body again. But yet again, the ball landed as far as it did the last time. "I didn't do it that time, did you let me get into your head or what?"

"Sorry sir, I just had a lot on my mind."

"One more time." Aizawa said as Izuku grabbed the ball once again. He closed his eyes and readied himself one last time, focusing the best he could on using his Quirk.

'I used too much the first time, and Mr. Aizawa erased my Quirk. I tried using too little and I wound up using nothing. What do I do?' Izuku closed his eyes and reeled back, ready to throw the ball. 'Wait! If I use it all on my arm then I'm going to break it, but what if I focus it at the last point of contact as I throw the ball? My fingertip!' Izuku felt the power of One for All surge throughout his body and into the tip of his index finger. He threw his arm forward, throwing the ball with all his strength and rolling it off his finger. The class looked on in shock as the ball skyrocketed into the air, blowing a gust of wind behind it that sent everybody backwards.

"What kind of monster is this kid?" Aizawa asked as Izuku's new score came in, seeing it was 705.3 meters.

"Who's a ragdoll? I've got the power to keep going!" Izuku yelled as he hid his now swollen finger from his teacher. Aizawa couldn't help but smile in disbelief before watching someone dash past him and towards Izuku.

"WHAT THE FUCK WAS THAT ALL ABOUT, DEKU?! AREN'T YOU QUIRKLESS, YOU LITTLE SHI-" Katsuki extended his hands forward, explosions sparking from his palms, making Izuku scream in fear. But before he could reach him, Aizawa's scarf had gone and wrapped itself around him, effectively keeping him in place.

"Damn it, don't make me keep using my Quirk...it gives me dry eye!" Aizawa yelled revealing that he had once again activated his Quirk, before pulling the boy back to the group. He sighed and deactivated his Quirk, taking out a bottle of eye drops and placing one drop in each of his eyes.

"Alright, I'm not gonna waste my breath to explain how the totals get calculated. I'm just gonna show the results, it's just the totals of all the tests added together." Aizawa said as he held his phone flat to project the results for the Quirk assessment. Izuku took a deep breath and looked at his currently bandaged hand, lucky for him that Hayato had more painkillers with him to numb the pain from using One for All before. The remaining tests all went as he expected, he did well on the sit-ups and seated toe-touch thanks to the kind of workouts he did with All Might, only the long-distance run gave him a hard time from already feeling extremely exhausted. He looked up and read the scores, smiling at the results.

"Oh and I was lying about expulsion, by the way." The entire class went quiet and looked at their teacher in shock as Aizawa revealed his lie to the class. "It was all a rational lie to get you to use your Quirk the best you could." The entire class, save for a few, let out a scream of shock: especially Izuku.

"Of course that was a lie. It should've been obvious if you thought it through." The girl Hayato talked to before said, looking at her classmates in disbelief.

'It wasn't obvious...' Was the consensus thought from the bottom five.

"Midoriya, is your finger healed?" Tenya asked as he caught up to the green haired boy after school. Izuku nodded and showed his currently bandaged finger making the taller boy smile. "You know, I was really taken aback by Mr. Aizawa. I thought this school is the best of the best...but to encourage your students on a lie? How absurd." Tenya said as the two began walking towards the school gates.

"Hey! You two! Going to the station? Wait for me!" The two turned around hearing running and saw Ochaco was making her way towards them.

"Uraraka?"

"You're the girl who scored infinity." Tenya said as the girl happy caught up to them.

"I'm Ochaco Uraraka. And you're...Tenya Iida." Ochaco said looking at the blue haired speedster. "And you're Deku Midoriya, right?"

"Deku?!" Izuku jumped hearing his childhood nickname come from her mouth.

"But that's what Bakugo called you during the test right?"

"Well...my name is Izuku but Kacchan gave me that name to make fun of me as a kid." Izuku explained while hiding an embarrassed blush from his two classmates.

"He gave you a name to insult you?" Tenya asked placing his hand on his chin.

"Oh really? I'm sorry about that...it just sounded really cute." Ochaco said making Izuku's blush take over his entire face.

"I'm Deku then!" Izuku yelled surprising Tenya while Ochaco smiled at him.

"You're accepting it too early! Wasn't that an insult?!" Tenya asked making Izuku hide his face before a thought crossed his mind. "Oh, Midoriya?"

"Y-Yeah?"

"Your friend, where is he?" Tenya asked making Izuku revert back to normal, realizing what he was referring to.

"Hayato went to see Recovery Girl to do something about his muscles still aching." Izuku explained making Tenya sigh.

"Oh, your friend is so cool! How long have you known him?" Ochaco asked as they continued making their way off campus.

"Well, he's been my best friend for over ten years now." Izuku said making Ochaco squeal in delight.

"He's a speedster like Iida, right?"

"Yeah."

"But I'm curious, when he did the 50-meter dash with me: he crossed in a second. But when we did the long-distance run: he was so much slower than he was before." Tenya said making Ochaco think back to that exam and nod as she remembered Tenya overtaking Hayato in an instant, the complete opposite of the very first test.

"Well you see, Hayato's Quirk can be seen in very different ways. But when it comes to how he maintains his speed is like a car: the faster you make it go, then the more gas it burns. Hayato can reach top speed instantly, but he can't keep it up for long." Izuku explained as he pointed at a car that zoomed past them when they made it to the sidewalk.

"But I heard that he ran so fast that he made a wall of wind during his practical exam and kept it up for the last two minutes." Tenya pointed out, making Izuku nod.

"He could, but look what forcing himself did to him. It's been over a month and parts of his body still aches. His Quirk damages his body more than people understand if he pushes himself."

"How so?" Ochaco asked getting her face close to Izuku's, unknowingly making him blush from his timid nature.

"W-Well, you know what Electrolytes are, right?"

"I've heard of them but I dunno what they are exactly." Ochaco said looking up in confusion.

"They're an extremely important mineral in our bodies, they carry an electrical charge that act like a sort of battery to everything in our bodies' systems." Tenya explained while Ochaco feigned understanding, while in reality she had completely zoned out when he started talking.

"Well, the way his Quirk works is that his body takes the charge from them and basically charges up his muscles. But the problem is that when you start having less and less, your body starts failing. Your blood doesn't clot and it becomes more acidic, if you have a wound then your body can't make new tissue to make scars, but the worst part is that they help send nerve signals across your body and your muscles start acting different." Izuku explained making Ochaco and Tenya's eyes widen. "They can't contract so moving your legs or arms or any muscle would be impossible or difficult, and the danger from that comes from our hearts being a muscle. I always tried keeping him from making a mistake like that because the last thing I ever wanted to see was my best friend running so hard that when he stopped: so did his heart. Thank goodness Recovery Girl helped him get more than enough back that day, now he's just suffering pain from over exerting himself to that extent."

"You two are really close, huh?" Ochaco said smiling at Izuku who returned the smile.

"The closest."
