He was late. That wasn't anything new, he was late more often than not, during his stay on I-Island he had been late to class just about every single day. It wasn't always his fault, sometimes something exploded other times he simply got distracted. But today it was his fault. He had slept through his alarm and now he was late.

On the first day of his new job. His dream job. The job he had desired for years. Ever since he finally accepted that he couldn't be a hero. But that didn't mean he couldn't help others become better heroes.

He was late for his first day of teaching at U.A.

And he was losing his mind. How on earth could this happen? Sure he had been freaking out last night and spent perhaps a bit to much time trying to make sure that his lesson plan was absolutely perfect and he woke up at his desk and -

Wait. He paused, the gate to U.A. was visible and closed tight. But that wasn't important. Well, it was. But the important thing that was important at this very moment was what he held his entire lesson plan. His All Might 2TB flash drive that he kept on the lanyard that David had given him his first year at I-Island U.

It wasn't around his neck. Not in his pockets. His pass was there, and so were his keys. But not the lanyard.

"Shit, shit, shit," He grabbed his bag spinning it around his shoulder. The shock gauntlet that Melissa had made for him was at the top and a variety of other gadgets, papers, a data-pad, a laptop, old granola bar. But no flash drive. At least not the one he was looking for. "Fuck."

He was late, unprepared, and he probably didn't look exactly professional. His tie was sloppy, his shirt untucked and his sweater vest wasn't aligned. And his socks weren't matching.

No doubt Melissa and David would be laughing their asses off if they saw him. Ahh, he should have stayed on I-island. Wait, no. Sure, he might have had David's offer to be a research assistant to complete his masters, but.

He looked up, seeing the glass towers of U.A. His heart swelling with purpose. This was where he needed to be. This was where he could do the most good. He looked at the closed gate. "But I can't do anything if I'm late!"

He sprinted towards the security gate, maybe if he knocked they'd let him in? Wait, the press was there. Did something happen recently? It was only a few days after summer vacation, did word get out of a new teacher in the middle of the school year? Crap that's what he gets for being late.

He looked at the security wall. Maybe if he was lucky the alarms wouldn't go off since he had a pass? It was high but he should be able to climb it with something in his. Ah! There it was. As to why he had a grappling hook in his bag, was probably best explained by why Melissa saw fit to make a grappling hook and place it in there.

It looked like an umbrella.

He walked up to the wall and breathed, holding up the grappling hook with both hands. "Sheesh, I wanted to become a hero, now I'm starting to feel like a spy out of a movie. All on my first day on the job. Fantastic."

He twisted the top and aimed it at the wall then pressed the power button. A thin green string shot out from the canister and latched on near the top of the wall, it looked slimy, glistening in the morning sun like dew on the grass. He pressed another button and the grappling hook flew out of his hands and stuck to the wall.

"Shit."

For the next five minutes, he jumped trying to reach the gadget not even getting anywhere close to it. Apparently, while a handheld grappling hook was more than possible, holding onto it was the hard part. "In hindsight, it probably would have dislocated my shoulder or something."

"Speaking of dislocated shoulders," A gruff growl of a voice drew his attention behind him. Behind him stood one of the most intimidating heroes at U.A. a hulking man with a wild mane of blond hair and a beastial appearance, his mouth covered by a muzzle, Ryo Inu, Hound Dog. The school guidance counselor. "Why are you trying to break into the school?"

"Oh, no! I'm not trying to break in. I'm… well the thing is. I'm, Uhh, I'm" He dug through his bag, pulling out his pass. "I'm the new teacher here. Izuku Midoriya."

Ryo growled glaring at the pass. "You know the doors open if you have one of those right?"

"Oh," His arms fell. "I did not."

"You know you're-"

"Late, yes, I know."

"Well yes, but your fly is also undone."

Today was so not his day.

XXXX

There was so much that she wanted to know. Why was Aizawa-sensei giving them a quiz? Would they be graded on it? Why didn't he have his own class? Why were they getting a new teacher right after summer vacation? What was quirk theory? Why were they late?

Nejire gave a small yawn spinning her completed quiz around on the table. They haven't even had hero training today and she was already tired! She was far too used to summer vacation and sleeping twelve hours every day. She really needed to be well rested to use her quirk later.

It was actually kind of hard to pay attention in class.

Aizawa-sensei looked comfortable in his yellow sleeping bag. Maybe he wouldn't mind if she just took a quick nap while the other's finished their tests. With another yawn she spread out onto her desk, pressing her cheek against it. Yep, she could sleep like this. She'd need all the energy she could get for hero training. Maybe she should become the Sleepy Hero Starlight.

"Nejire." Aizawa's sharp voice prevented her from closing her eyes. His own dead tired and sleep deprived eyes glaring at her as he sipped some kind of a juice pack. How could someone look so comfy but be so grumpy? "No sleeping in class."

"Ahh come on sensei," one of her fellow 2-B classmates said loudly, it was Hayai, the dog-faced boy that was one of the better students in their class, despite his hyena-like face and annoying habit of laughing like one, his quirk was that he could move fast, fast enough to run on water. "Nejire needs to rest up so she doesn't end up passing out using her quirk again."

Half the class laughed or snickered at that, leaving her cheeks burning. It wasn't like that happened every time, just a few times. Like the sports festival. Twice. If only her quirk didn't use up so much energy.

"Hey, back off," Mirio the tall nice blond nice guy, that would stand up for anybody, that sat two desks back from her said. "She wants to be a hero just like the rest of us."

Hayai cackled, "And what are you going to do about it? Fall out of your clothes again?"

Pointing out that he tripped three times during the relay race event would only make him angry and would result in more teasing. He wasn't even an interesting person. He was just a jerk.

The door opened, and in walked a lanky plain looking guy with freckles on his face and a head full of messy green hair that was haphazardly pulled into a ponytail. His shirt was a white button up that was partially covered by his sweater vest. A large black messenger bag was hanging off his shoulders. After being at U.A. for a year she had forgotten what a teacher was actually supposed to look like.

"Sensei!" The green haired man bowed deeply at Aizawa, "I'm sorry I'm late," He stuttered clapping both hands over his head. "Thank you for covering me."

"Don't thank me yet Midoriya," Aizawa growled finally stepping out from his sleeping and glaring at their new teacher. "I don't tolerate tardiness, and it's not something you should either, that said, I will be the teacher evaluating you going forward."

"Right!" Midoriya-sensei clapped his hands again and stood straight, shoulders back looking proud. Then he looked towards them, his shoulders fell and his posture crumbled. His mouth moved but no words came out.

Aizawa coughed.

"Right!" he said loudly resetting and marched towards the whiteboard. The marker screeched as he spelled his name on the board, both in Kanji and English. "My name is Izuku Midoriya, and I will be your instructor in quirk theory and applications!"

He turned towards them, blinking for a moment before digging into his bag once more. A moment later he sighed and put the bag back, a small frown on his face. "Right then, Uhh, I suppose I should explain what exactly that is, unless anybody has any questions first, or should I save that for the-"

"Where are you from? How old are you? Why are you teaching us?" She asked all but jumping out of her seat. "What should we call you?

"Oh, uhh Nejire Hado right?" He asked nodding to himself before she could respond. "Your quirk is called wave motion right, and you can use your own energy to produce powerful blasts."

"Ha, if she could hit anything." Hayai snickered.

"To answer questions, I'm local, but I studied at I-island for a few years, I'm 21 years old, and I'm teaching you to help you make a difference in the world." He shrugged turning back towards the board, writing down what looked like a lesson plan. "And you can call me Midoriya-sensei. Is there anything-"

"Is that your hero costume?" One of her classmates asked.

"What's your hero name?" Another asked.

"What's your quirk!" She joined in raising her hand. He was so young for a teacher He was around three years older than her! That was so cool, and quirk theory sounded exciting.

"Oh, uh," His nervous smile vanished and he rubbed that back of his looking sheepish. "I don't really have any of those things, I'm not a hero, and I don't have a quirk." he shrugged. "I'm just a quirkless guy that likes quirks."

"What the heck!" One student shouted.

"Aizawa-sensei!" Hayai pointed at him with one hand open. "What on earth can this quirkless nobody teach us about being a hero?"

Midoriya-sensei looked down, turning his attention to his bag once more.

Aizawa glared at the obnoxious punk. "You-"

"Aizawa-sensei," Midoriya-sensei interrupted, his voice was firm. "Let me handle this. To answer your question Hayai, I'd like to use Aizawa-sensei as an example. You see, when you fight against him, you specifically are quirkless, indeed if you're not a mutation type chances are if you fight Aizawa-sensei you're going to lose." Izuku looked up, pulling out a few stacks of books. "One half of quirk theory is to help you analyze quirks that might cause you problems, or even quirks that won't cause you any problems."

"The other half, is-" He pulled out a few more notebooks. They were all fresh, and clean. "Understanding your own quirk so that you can improve upon yourselves and become the best you, you can be."

"And how are you supposed to do that?" One student asked. "You don't know anything about our quirks."

"Midoriya-sensei." Aizawa stepped forward, a serious scowl on his face as he stressed that word as though to remind them that they should be showing him so much more respect than they have been. "Has forgotten more about quirks in four years than you will ever know. If you cared half as much about your own quirk as he cared about any quirk, you might just make a halfway decent pro."

Midoriya-sensei's cheeks went flushed, and his fingers drummed over the edge of the podium, his eyes locked onto the notebooks as he sucked on his lip. He took a short breath and looked right at them, before closing his eyes for a long time. "For someone with a relatively basic quirk that just makes you strong, makes you faster. With, simple stuff like that I suppose that understanding your own quirk isn't really that important. Besides," he drummed his fingers and slapped his hand on the podium, before turning to pace in front of the white board.

"It's your quirk, right? Who would know it better than you? So why should you listen to me? I don't even have my own quirk so how could I ever help you understand yours?" Midoriya-sensei turned and looked at them all. The fidgeting he had shown earlier was all but gone as his hands were balled into tight fists. "But, I think that I should be able to show it to you. So let's skip to the practical portion for today, and I'll show you why not only understanding your own quirk but your opponent's quirk as well can make a difference."

"The gymnasium should be free right now." Aizawa huffed his shoulders, a small smile cracked on his face that looked nothing but creepy. "I look forward to seeing the results."

In a few minutes, they were dressed in their gym clothes and standing in one of the plainer gyms with only a few concrete walls acting as obstacles on otherwise flat ground. She stood near Mirio and Tamaki, really aside from Yuyu, they were her closest friends and she wasn't in the hero class.

Aizawa-sensei stood near the door, arms crossed, still looking like he was ready to expel them at the drop of a hat. And she really wanted to know if they were going to be graded on that quiz. But asking him was kind of scary!

Midoriya-sensei stood, still dressed exactly how a teacher should be dressed, smiling meekly at them. The confidence he had early was all but gone.

"Sensei!" She held up her hand. "What are you going to show us?"

"Oh!" He jumped, looking around and flexed his fingers once more. "Well, I was uhh," He took another breath. "Right then. Hayai Savah, your quirk is speed right, and you placed third during the sports festival correct?"

"Yea, that's right," Hayai cackled one hand rubbing his snout. "Nice to know you've done your research, sensei." He spoke that last word mockingly.

"I spent the summer researching and analyzing all of your quirks, even calling in your sponsors from both years." Midoriya-sensei nodded, before gesturing towards his side. "Why don't you come first, I want you to pick your opponent, preferably someone that you know you'll beat."

"Ha!" The Hyena faced jerk barked. "I can beat a slowpoke like Nejire every day of the week."

He wasn't really wrong. He could move faster than her wave blasts if she could even fire one before he got to her.

Midoriya-sensei clapped his hands smiling brightly. "Alright then, Nejire, please come on over here."

She wanted to protest, to try and get someone else to do this. But she was one of the people to ask him what his quirk was. She really needed to work on being more sensitive with her questions. Mirio pushed on her back and she stepped forward, turning back to see him give her a thumbs up.

"Okay sensei." She might have dragged her feet heading over to him, biting her lip as she stared at Hayai. She was so not ready for a sparring match right now. Even her stomach was roiling, making the room spin. If she unleashed to strong of a blast she'd probably pass out. But there was no backing down.

She stood next to Midoriya-sensei and flopped her arms. "What am I supposed to do."

"The Objective will be to knock the other person on the ground first, I'd rather not have recovery girl mad at me on my first day." A few students chuckled at that. He gestured away from where Hayai was standing and walked with her the rest of the way. "Is it okay if I whisper in your ear?"

She nodded and he leaned in close. His arm hovering over her shoulder like he was trying to keep others from seeing them. He was so close! "His quirk isn't really speed, he can only travel in a straight line and anything that's more than a few inches difference can cause him to trip. He also has problems slowing down, his quirk might just be something closer to linear acceleration. I don't know, it's really interesting how it works because he always looks for where he's going to go it could be something-"

"Sensei," she said looking him in the eyes. "I think you're mumbling."

"Oh, sorry," He placed a hand over his mouth to hide his smile and his blush. "I really like quirks."

It was kind of cute how excited he got about them.

"So, what do I do?" She asked keeping her eyes focused on him. "Even If I know where he's going to be, I can't hit him, he's too fast."

"You're not going to hit him." His smile only grew. "You can channel your quirk into your feet right?"

"Yea," she nodded. "It's harder to aim but It's just as easy as my arms." She could really do it from any part of her body, but a stomach wave was kind of hard to aim.

"Alright, right at the start channel a big blast directly into the ground."

"Uhh, okay." She had no idea how that was going to do anything, well it was going to be quick no matter what she did.

"Are you ready?"

"Uhh, I think so."

"Right then," Midoriya-sensei backed away, holding one hand up in the air. "First, one to knock the other on the ground wins."

"This will be easy." Hayai taunted, popping his shoulders and stretching his legs.

She nodded taking a breath and focusing on her legs. Just channel a big blast into the ground. That should be easy. She was good at hitting the ground. Was it cheating that she was already gathering energy to use in her quirk? Hopefully, this would go well.

"Three."

"Two."

"One."

"Begin!"

She closed her eyes, releasing the energy pent up in her legs. First, the ground cracked, then the wind blasted her in the face. Then she found herself weightless. She opened her eyes. To find herself five feet off the ground. A sudden sense of vertigo overtaking her like her blood sugar had just dropped to zero. Yep. She used too much power. She could barely move her arms.

But, she could scream. She shrieked for half of a second as she began to fall back towards the ground.

"Nejire!" she heard Mirio and a couple of others call out to her. This was going to hurt.

"I got you!" Somebody caught her, breaking her fall into two stages, crashing into him, and then both of them crashing onto the ground, mostly unhurt. "Are you okay Nejire?"

She opened her eyes, finding herself awkwardly across the now prone Midoriya-sensei, who was halfway under her. She pushed herself up, arms trembling and feeling rather cold. "I'm not hurt. Just tired."

"Right, sorry," He got up, helping her up in the process. "Forgot your quirk uses your own energy. But hey, you won."

That woke her up. She blinked focusing on the ground, a perfect spiral of concrete had risen out of the ground about a foot at the center and tapering off. At the outside edges. And on the other side, pushing himself up off the ground was Hayai, his knee bloodied.

"I won?" She asked looking at Midoriya-sensei, still holding onto his shoulders. She tripped him? By making the ground uneven with her own quirk. Why didn't she think of something like that?

Her new sensei nodded smiling at her. "I knew you could do it. You have a really amazing quirk. You just need to train it."

XXXX

"I'm reducing the size of your class." Aizawa said the moment they entered the teacher's lounge.

He stopped in his tracks the door sliding to a stop. "What? Why? Was it that bad?"

Most of the students that followed his advice had come out on top or at the very least performed marginally better than they had in previous matches. But this wasn't just something that could be shown with just a single day. He needed more time. "I need more time sensei please! You know how long it takes to make a difference it's too soon to-"

"This isn't about making a difference." Aizawa muttered sitting at his own desk and pulling at a binder. "This about training you, I had a feeling that you were to young to handle so many students at once after never teaching a day in your life."

"I've given lectures."

"To I-island university students, not heroes in training."

He had half a point at I-island the worse he ever got was someone snickering at bad grammar or something equally mundane.

Aizawa looked at him, pulling out a pen and opening up one of the binders. "I don't have a class of my own this year, instead I'm trying to make certain that your class is worth something, personally I think that it is. But, I also think that thirty students is out of your skill range. Now, let's discuss what students would benefit most from your class."

He took a small breath, taking the seat next to Aizawa and looking over the the roster. A smaller class would help him teach. "Sensei, I promise that in the next sports festival the top three places will be held by my students."

A wild smile grew on Aizawa's face. "I look forward to seeing the results."

AN: I wanted to write Izuku x Nejire again, and this was one of the ideas I came up with. To start, she's currently 17, a 2nd year U.A. student, she also hasn't actually gone through much of her training, so she's kind of a lot weaker right now. She can't even fly!
