Today was a good day. Or at least it should have been, if not for a certain blonde menace who seemed to have made it his mission to be as irritating as humanly possible.

Tenya sighed into his hands, exasperated. U.A. was supposed to be a school for elites; he couldn't believe they'd let a delinquent like this attend! It was a disgrace, it was.

"Please remove your feet from the desk!" he tried for what was probably the third time, waving his hands furiously. "Not only is it bad manners, but it is also disrespectful to all students who have used this seat before you and those to come!"

They boy just grinned cruelly at him. "Make me."

Then he kicked at the table for emphasis, loosening flakes of dirt from the soles of his brown shoes that rained down onto the surface below. Tenya opened his mouth to protest at this rude and shameful display of blatant disrespect, but before he could voice his thoughts he was interrupted by a cheerful voice calling out "Good morning, Kacchan!".

Tenya and the blonde hellion turned around at the same time to address the newcomer and found a pair of large emerald eyes staring back at them.

"Deku," the rowdy teen said, giving a small nod of acknowledgement. The new boy smiled, but when he noticed Tenya his expression fell.

"Oh," he uttered, shifting his gaze back to the blonde. "You aren't causing trouble already, are you Kacchan?"

'Kacchan' snorted. "I don't need you scolding me, mom. "

Tenya observed the freckled and curly haired boy for a moment. He thought he recognized him from somewhere.

That's right, he remembered now! He was the boy distracting all the other participants with his incessant muttering during Present Mic's introduction to the U.A. entrance exams! Great, more trouble.

"Looks like my seat is behind you," the small boy addressed his delinquent friend. "Isn't that great?"

Tenya wondered if this boy was a delinquent too. He didn't look the type, but appearances could be deceiving. A wolf in sheep's clothing, as the idiom goes.

"You think I care?" the troublesome blonde dismissed his friend with a scoff. The other boy payed no mind to the biting comment, instead focusing his attention to Tenya.

"I'm sorry if Kacchan is causing you any trouble," he apologized with a timid smile. "But please don't think any less of him! We're all here to become heroes, right?"

The blonde reacted at this. With a narrowed eyes aimed at his friend he said: "I don't need your help, Deku. Ignore shitty glasses; I didn't come here to deal with some prissy, stuck up elitist."

Tenya was taken aback by the insults, shocked by the boy's rudeness. He furrowed his thick brows deeply and was just about to retort, but before he could get a words out he was interrupted for the second time today.

"It's you!" yet another cheerful voice joined them, but it belonged to a female this time. "I'm so glad you got in, Midoriya-kun!"

"U-Uraraka-san!" the green haired boy, Midoriya, greeted the round faced girl sporting a brown bob haircut. "You got accepted too!"

"Yup!" she replied with a big smile. Tenya eyed her critically, praying that she wasn't here to cause trouble as well. "I look forward to being friends with you."

"F-f-friends?!" Midoriya stuttered as his face turned increasingly red. "O-of course! It would be an honor!"

He bowed deeply and Uraraka giggled. His blonde friend meanwhile looked on in mild annoyance while Tenya was left completely ignored.

"The hell are you bowing for, stupid Deku? You're embarrassing yourself," the delinquent said, the corners of his mouth turned down in disapproval of the freckled boy's actions.

"S-sorry, Kacchan…" Midoriya apologized after he returned from his bow.

"And stop apologizing so much, it's annoying."

"R-right!" the emerald eyed boy nodded with his fists raised in the air. Finally Tenya found a good moment to chime in and prepared to speak—right before the classroom door slid open for a third time in this short span of time and a tired voice spoke.

"Alright, simmer down, take your seats and be quiet."

The previous jovial chatter of the class (and watching the drama unfold between Uraraka, Midoriya, Tenya and the blonde boy) died down into complete silence as they all saw the prone form just outside the door to their classroom. Tenya stared in disbelief, taking in the appearance of the man—their teacher?—laying on the floor, wrapped up in a bright yellow sleeping bag. His shaggy appearance and unshaven stubble made him looks like a homeless person. Sufficed to say, the blue haired teen was not impressed. Was this really what U.A. had to offer? Delinquents and faculty member's who looked like they belonged on a park bench more than they did in a classroom?

But the bespectacled teen did not voice his thoughts aloud. Instead, he quietly took his seat, but not before casting one last distasteful glance at the blonde menace for good measure, who narrowed his red eyes just as fiercely in response, before concentrating on his new teacher's words.

He introduced himself as Aizawa Shouta, before he announced their class would forego the opening ceremony in favor of a quirk evaluation test. Tenya did not know whether he should respect his teacher for focusing on their education rather than waste time with unnecessary customs, or disapprove of him breaking tradition.

The quirk evaluation test was just what it sounded like. Students would go through a series of different physical exercises in which they were allowed to use their quirk as they saw fit to obtain the best result. One of the students—Bakugou Katsuki, the troublesome delinquent from this morning—was called up by Aizawa to demonstrate.

It was a ball throwing test, and with a shout of "DIE!" and a bright explosion, the ball was sent flying, becoming an increasingly small dot in the distance before eventually disappearing. Tenya had to admit, the boy's quirk was certainly impressive, but his attitude needed some severe adjustments before he could be called hero material.

With a blank expression Aizawa displayed the results: 705.2 meters. Several hushed whispers of amazement ran through the class. "So manly!" someone whisper-shouted from somewhere behind Tenya.

"Oh, and whoever gets the lowest overall score is expelled," their teacher announced after the whispers finally died down and Bakugou returned to the fold, which only caused the commotion to immediately start up again, only this time much louder than before. The large grin that accompanied Aizawa's words did little to calm the students down.

"Expelled?"

"What does he mean expelled?! Can he really do that?"

"And I just barely got in!"

Tenya stayed quiet. He was confident in his abilities to pass, but he'd be lying if he said he wasn't at least slightly nervous. This is what I've been training for, he reminded himself. He came from a family of heroes; he was born to do this! If he failed now, he could never look his brother in the eyes again.

He did feel some preemptive sympathy for whoever wouldn't make the cut—not that he didn't understand his teacher's reasoning to expel someone with no hero potential, but it did seem a bit harsh.

He shook his head to dispel the distracting thoughts. He couldn't worry about that now, he had to concentrate on himself and make sure he got a result he could be proud of! There were many impressive quirks here and while he was very proud of his Engine, he knew it wouldn't be able to measure up to some of his classmates. He couldn't afford to slack off.

He pushed his quirks to it's limits, only stopping short of revealing his Recipro Burst—he didn't want his classmates to know about that quite yet. He could tell everyone else were giving their best as well—almost everyone, at least. From what he could tell, the Midoriya boy hadn't used his quirk once, and he was falling behind.

Was his quirk not applicable for these exercises? Or was there something else? How did he get accepted to U.A. in the first place?

His musing were cut short when they all finished up the last exercise. The whole class was a bundle of nerves while they all waited for Aizawa to announce their scores and ultimately decide the fate of whoever ended last. Midoriya was practically shaking and his troublesome friend slapped a hand on his shoulder to keep him still.

Class 1-A all took a collective deep breath as the scoreboard was displayed, projected as a hologram by the device their teacher had used earlier to measure their scores, and released it simultaneously once it was clear they didn't place last. Well, aside from one students of course.

Midroiya face was beginning to turn red when he still hadn't expelled the air in his lungs and his friend had to slap his back a few times to remind him to breathe. Now he was just staring dumbly at the last name on the scoreboard. Midoriya Izuku.

The small boy was already garnering sympathetic glances from the rest of the class as he seemed to deflate on himself and finally ceased his shaking. His blonde companion however didn't even so much as look at him, his gaze to busy focusing elsewhere. Namely, on Aizawa.

He was glaring. It wasn't the same kind of glare from this morning, the kind who looked at Tenya as if he were little more than a bug to be stepped on. This glare was much more intense, the red eyes seemingly aglow from the heat contained within. Tenya was ashamed to admit he was glad it wasn't directed at him, but Aizawa didn't look like he even noticed the blonde who was currently trying to set him on fire with his eyes alone.

"Bullshit," the agitated blonde ground out, effectively drawing everyone's attention from the unfortunate boy who would be expelled on his first day of school to the explosive quirk user. His hand, which was still gripping his green haired friends shoulder, tightened dangerously and Tenya could tell by Midoriya's soft grimace that it must hurt.

Aizawa just looked at him blankly, unimpressed. One eyebrow raised questioningly, but it seemed more of a formality than anything. "Do you have any complaints, Bakugou?" he asked in a too tired, too bored voice. Bakugou's eyebrow twitched.

"Damn straight I do. What the hell is this bullshit? Just because Deku's stupid fucking quirk is useless for your stupid fucking tests, you're gonna throw him out?"

"That's the idea, yes," Aizawa answered, looking like he wanted nothing more than to go take a nap in a corner somewhere. But Bakugou wasn't finished.

"What kind of logic is that?!" he roared, letting go of Midoriya and taking a threatening step forward. His friend looked surprised by the outburst and wisely cowered at a safe distance from the blonde's twitching fingers.

"Kacchan…" he tried, but Bakugou just turned his heated stare to him instead.

"Shut up Deku," he ordered before he turned back to face their shaggy looking teacher. "I'm not gonna let Deku get expelled after I spent months training his useless ass, just because of some flawed 'quirk evaluation' test," he declared boldly, challenging any who dare oppose him—which in this case would be their teacher.

"Oh?" the person in question replied. "So you think Midoriya has what it takes to be a hero?"

Bakugou was silent for a moment. He glanced back at his freckled friend as if sizing him up. Then, he turned his gaze to roam over the rest of their class and spoke.

"More than these extras do."

The audacious comment sparked cacophony of sound. Each student was protesting his claim, in varying degrees of loudness.

"Hey!"

"Extras?"

"You could have just said 'yes'!"

Tenya was tempted to chime in himself to scold the brash teen for his insolence, but decided against it. Especially after their disgruntled teacher glared at them all. He was only looking more tired by the second, and no one aside for Bakugou wanted to test his patience any further, lest they all get expelled.

Or not.

"Um," a timid voice spoke up, belonging to Uraraka Ochako, who looked somewhat unsure of whether she should continue or not once everyone's eyes turned to her.

She did anyways.

"I don't know about 'extras', but I believe in Midoriya-kun as well!" she smiled, pumping her fists in the air. "If it weren't for him, I'm not sure I'd be here now."

Tenya quirked an eyebrow at that. He didn't know what the girl was talking about; what did Midoriya do that was so important? He had to make sure to ask her about it later.

But that proved to be unnecessary as Aizawa answered his unasked question in his next sentence. "Ah yes, he pushed you out of the way of a falling pile of debris during the entrance exams, correct?"

Uraraka nodded in confirmation. Tenya perked up at this new bit of information and glanced over at Midoriya in surprise. The boy was currently chewing on his lip anxiously and glancing between Bakugou, Uraraka and their teacher. He jumped when Aizawa addressed him, who was still wearing the same expression of boredom that seemed to be permanently affixed to his face.

"And is this how you plan to become a hero?" he asked. "You think you can save people by injuring yourself in their place? If it weren't for Uraraka's quirk, would you have been able to free yourself?"

"Um…" Midoriya hesitated, lowering a his gaze to the ground and tugged at the hem of his gym uniform nervously. Apparently realizing that his teacher was right, he hung his head in shame and answered negatively. "No."

"And I hope you realize you can't expect a civilian or other heroes to come to your rescue whenever you hurt yourself," the sleep deprived teacher continued, mincing no words to spare the freckled student's feelings. Midoriya just nodded in defeat.

"I understand," he sighed in agreement. He looked frustrated, biting his bottom lip and furrowing his brows deeply. He looked like he wanted to say something more, but refrained, just nodding solemnly at his teacher's words.

But Bakugou wasn't satisfied. "Yeah, Deku fucked up as usual. But it's your job to teach him how to not be so useless, isn't it?"

His green haired friend glanced toward the blonde while their teacher adopted an expression of complete unamusement. They held a silent staring contest for a minute. Aizawa was the first to blink.

"...you're right. But there's no point in teaching someone with zero potential," their teacher spoke, breaking the silence. Something flashed in Bakugou's eyes for a moment hearing those words, but it was gone just as quick as it came, and his face settled pointedly.

"Deku isn't weak," he declared. His tone and expression left no room for argument and people were quietly glancing from him to Midoriya. His green haired companion lifted his head to stare at his friend, his big green eyes opened wide in wonder. He still looked nervous, but a small smile now graced his lips instead of his previous deep frown.

Aizawa didn't answer immediately, but eventually spoke as he reached a decision. With a deep sigh and muttering something about "not being paid nearly enough to deal with this" he responded.

"Fine," he said, even if he still didn't look completely convinced. But there must have been something in Bakugou's eyes or voice that convinced Aizawa to let the freckled boy stay. "Midoriya will get another chance to impress me, but if he fails to deliver, it won't matter how much you curse or yell at me. He's out. Is that clear?"

Midoriya nodded his head frantically, grateful tears springing up in the corners of his eyes. Bakugou scoffed dismissively, but did give a curt nod of confirmation. Uraraka smiled in relief and gave Midoriya a quick thumbs up, while the previously tense atmosphere of the class dissipated and everyone began chatting animatedly with each other about what just happened after their teacher dismissed them. Aizawa sent one last meaningful look towards the green haired boy who gulped nervously in response.

Tenya decided that now would be a good time to approach the freckled teen. The boy startled at his approach and looked nervous as he addressed him. "Can I help you?"

Tenya took a deep breath before bowing deeply. "I would like to apologize!"

"H-huh?" Midoriya looked startled, face painted in surprise at the blue haired teen's sudden apology. Tenya continued.

"I seem to have misjudged you," he admitted as he straightened his back, returning from the bow. "I thought you were just here to cause trouble, but I admit I may have made a mistake.

"A hero's first priority should be to protect others. I was not there to see it, but from Uraraka-kun's and Aizawa-sensei's words, it sounds like you sacrificed your own safety for someone else's. Is this correct?"

"Um, yeah… I guess," Midoriya scratched the back of his fluffy head awkwardly. Tenya nodded.

"I initially had my doubts, but by that information I can tell you are serious about your convictions to become a hero. Again, I apologize for judging you so quickly."

The other boy finally seemed to relax and his round face melted into a soft smile. "It's fine. I thought you were kind of scary at first, but now I see that you are just very earnest."

Their conversation was interrupted by a loud voice shouting at them. "Hey Deku! Get your ass over here, or do you want to get late to class?"

Unsurprisingly, the voice belonged to no other than Midroiya's blonde friend. His gaze lingered on Tenya for a moment and frowned, but didn't comment any further. Just motioned with his head for his green haired friend to follow.

"Coming Kacchan!" Midoriya replied before turning back to Tenya. "See you in class!" he smiled.

Tenya nodded. He looked to Bakugou, and before Midoriya was out of earshot, he spoke. "I have to say though, I'm surprised that you are friends with someone like Bakugou-kun."

The freckled boy paused in his step, turned, and looked at Tenya with his brows furrowed and mouth set in a frown. "Pardon?" he asked.

"It's unexpected, is all. A troublemaker like him is hardly befitting of becoming a hero," the bespectacled teen answered honestly. "Besides, he should treat people with more respect. His friends, especially."

Tenya gave the boy a pointed look, but Midoriya's expression didn't relax. He eyed the blue haired teen watchfully before he spoke.

"Kacchan will become a great hero," he said, and his frown deepened. "And you shouldn't talk about things you don't understand."

Then he turned on his heel to catch up to the spiky haired blonde. Tenya was fixed in place, taken aback by the seemingly timid boy's sudden hostility. Did I say something wrong?

He stood there, honestly not sure whether he should apologize to Midoriya or not. Shaking his head, he began walking back toward the school building, not wanting to be late for class. He passed by the gravity girl, Uraraka, who was staring after Bakugou and Midoriya walking side by side, a thoughtful look on her face. She smiled at Tenya when she noticed him and fell in step beside him.

"You spoke to Midoriya," she stated simply. Tenya raised a thick eyebrow questioningly.

"Indeed I did," he answered. He let out a small sigh. "But I'm afraid I might have offended him."

"Yeah, I saw," Uraraka responded. "You did kinda speak ill of his friend right in front of him."

Tenya let out a frustrated huff of breath. "I was only being honest. Forgive me, but I don't think friends should call each other useless or tell them to shut up."

"Maybe," the small girl said. She worried her lips with her brows pulled together for a moment, before relaxing. "Or maybe that's just how Bakugou-kun communicates?"

She spoke aloud, but Tenya had the feeling the question was directed more to herself rather than him. Not that he had an answer to give her either way.

The rest of the trip back to their classroom was spent in silence.

Deku was humming happily, a soft smile on his face.

"What?" Katsuki snapped after the constant droning noise was too much for his frazzled nerves to take; he was still in a bad mood after the whole ordeal with Aizawa. Deku just smiled wider.

"Thanks, Kacchan!"

Katsuki stared at his beaming face for a few seconds. Then he scoffed, pushing Deku's face away with the palm of his hand.

"Whatever."

AN: Boy, I hope I made Iida justice. I felt like I wrote him a bit to mean, maybe? I dunno.

Well, maybe not the most exciting chapter, but it had to happen. I've decided in what direction I want this story to go; basically, I'll be following canon as much as I can, and see how much Deku's new quirk will change stuff.

Also, people correct me if I did any mistake with the honorifics. It's kinda hard to keep track of what everyone calls each other. I actually looked up an episode to see what honorifics Aizawa use when talking to his students, but I didn't notice any? Granted, it was just one name I heard, so...

And I hope I did Aizawa justice too. I feel like he's very stubborn so it's hard to win an argument with him, but I also feel like just doesn't have the energy to deal with an angry Katsuki. (Seriously, who would?)

Oh, and one more important thing... so, I talked about how I might turn this into Bakudeku before. And while I do love that ship, I'm not entirely sure any more. Please don't be too disappointed! :( It's just... I have no clue how to write romance. Bakudeku is still not completely off the table, but just a warning. But even if their relationship won't turn romantic, they will still grow very close! That's like the most important aspects of this fic: Deku's time manipulation quirk and his relationship with Katsuki.

And this information isn't really important, just some behind the scenes stuff that I thought might be interesting. When I was first coming up with Izuku's quirk I, I had this idea that Izuku could only rewind time on the world around him. But when he does, people wouldn't notice when he "teleports". Basically, their memory of watching Izuku use his quirk would "correct" itself to whatever the mind deemed most logical. So if Izuku used his quirk to teleport a short distance, to any spectators, their mind would correct it to Izuku just being a really fast runner, or something along those lines.

However, this only works in person. If someone were to record Izuku teleporting and rewatch the footage, they would notice that hey, that dude just teleported! I thought that would have been kinda cool (and really scary!) and Izuku would have been more free to use his ability but would eventually be discovered through a recording of him teleporting, but I decided against it for different reasons. But hey, if you wanna use this idea, go ahead. I still think it would have been really cool.
