Shota Aizawa, also know in the Underground Heroics circle as Eraserhead, was walking to U.A. for the first day of the new school year. He had reached the wall of U.A. and was now walking around to one of its few entrances. It had been roughly twelve months since the Rapture, and the headache that had been getting the world back on track was mostly complete. So that meant it would soon be time to deal with a new set of Hero Course first years. He could already feel the migraine.

They were always such a handful. Cocky at being accepted into the best school in the country, usually expecting to coast by on whatever lucky Quirk they got 'blessed' with, and children of Pro's who think their family name is enough for them to do whatever they want. There was a reason he threatened to expel most of his class each year.

Sure, it was an extreme measure. But some of them really needed a reality check. Besides, Nezu usually pulled some magic to remove any black marks from the record afterwards (as long as they corrected their behaviour). He saved the real expulsion for the truly fringe cases. Fortunately, it had only happened once or twice. Nezu was good at catching red flags early.

This time though, for good or ill, his migraine was due to a different reason entirely. Nezu had shown him the class roster, and he was going to be a part of his class. Class 1-A was going to have an extra student this year. Why? Because one of them technically already had a Hero License. And not just a provisional one, like the second and third years. An honest to god full Hero License.

He'd only met the brat once or twice, and he's already made his life a living nightmare. And no, getting that extra Quirk did not make up for the hell that Hizashi was now capable of.

Shota had hoped that walking to school from home instead of just sleeping in the staff lounge overnight like usual would give him enough fresh air to calm down, but it did no such thing. In fact, it made things worse, as he could see the spires of the main building, the source of his growing headache, approaching on the horizon. He couldn't think of a way it could get any worse.

"Hey, Eraser!"

Never mind, it got far worse.

Shota glanced up to see a familiar face approaching. One he hadn't seen in person for a couple years now. Koichi Haimawari, also known infamously across Japan as The Crawler. He let out a sigh as he saw the vigilante using his Quirk to approach him along the side of the wall, instead of walking like a normal person.

A flash of Erasure, and the young man's repulsive fields on his hands and feet turned off and he tumbled to the ground. He let out a grunt, but remained unharmed due to wearing actual gear instead of that god-awful All Might Hoodie, quickly getting up and waving to Shota. "Ah come on, Eraser! Don't tell me you haven't loosened up at all since we last met?"

"Last I checked, public use of your Quirk is still illegal. Especially on my school's wall, Crawler." He grumbled as he kept walking. "Last I checked you only had an American Provisional License. Only a full license lets you use Quirks in Japan, and only for Hero work, obviously."

"You know it's Skycrawler now!" Haimawari laughed and started to walk alongside him. "And just so you know, I already have a full license now. A Japanese one!"

Shota stopped walking, turning to Haimawari, who now held a smug look on his face. He was rather surprised at such a statement, but a quick flash of a card from the young Hero proved his words true. He squinted up at him suspiciously. "How?"

The idea that The Crawler would ever be allowed to do hero work, legal or otherwise, within Japan should have been impossible. For better or worse, Koichi Haimawari had made himself the country's most famous Vigilante in decades. Whereas most usually ended up getting arrested or disappearing after one or two stunts, Haimawari managed to luck into the perfect scenario to succeed as one. An area with a low number of Heroes, high crime, and a population that weren't averse to Vigilante assistance. As well as a good mentor in the form of another Vigilante with excellent skills to pass on, even if he was rather… intense.

And most importantly, great subconscious reflexes and a truly selfless attitude.

But after getting wrapped in one to many high profile incidents, the last of which resulted in the entirety of the Naruhata Ward nearly blowing up while being specifically targeted by the perpetrator, the heat became too much. The only thing that prevented him from getting locked up after that was the amount of outcry against it from Naruhata residents, if only because that delayed the arrest long enough for Captain Celebrity to spirit him away to America to take on as a sidekick.

Unfortunately for him, the press and tabloids loved his story, and he became a household name for a while. There was plenty of cries to overlook or pardon his crimes due to his exemplary achievements, but the government took a hard stance against it. Or to be more precise, the HPSC did. It seemed they didn't take to having their incompetence in ensuring the safety of Naruhata Ward exposed and put pressure on the government to ensure that The Crawler wouldn't be allowed to set foot in Japan again, except in handcuffs. They may have dressed it up by stating the need to uphold their hardline stance on Vigilantes, but Shota had been in the business long enough to read between the lines.

"Turns out knowing a guy that helped save the world has its perks." Haimawari said with a smirk. "Master put in a good word for me to Nezu, and Nezu put in a good word to the new HPSC President."

"And they accepted?" Shota still found that hard to believe. Even with all the changes to the agency after The Incident, walking back such a decision seemed unheard of.

"Nezu convinced him that giving me a license was 'long overdue' and 'a much needed act of goodwill' that would help improve their plummeting PR." Haimawari said with obvious air quotes. "So, after signing a few documents, my previous acts of vigilantism have been pardoned and I'm now an official Japanese Hero. About time, eh?"

Shota rolled his eyes but didn't disagree with the sentiment. "The blacklist on you had always been illogical, only existing to appease the old HPSC President's wounded ego. But now what? Are you going to be putting an Agency together, or just go back to helping old ladies cross the street and rescuing cats from trees in Naruhata?"

Now it was Haimawari's turn to roll his eyes. "I'll probably do a patrol or two around the old turf, but I'm working under Master again, now that he's back in the business. Can you believe it? He got his Quirk back and looks a decade younger as well! He still won't tell me how that happened."

"It's probably classified. What isn't when it comes to all of that." Shota said with a shrug.

"Fair enough. I mean… aliens?" Haimawari said with a disbelieving eyebrow.

Shota just kept walking. In truth, he knew the secret of O'Clock's mysterious return. Nezu had to inform him of Eri and her Quirk for safety reasons. That still didn't make finding out that the muscle-bound maniac boxer of Naruhata, Knuckleduster, had been such a high-ranking Pro Hero the whole time any less surprising. His pristine image of the High Speed Hero had been irreversibly damaged, and continued to be damaged every time they ran into each other.

"But if I'm being honest, Heroics was always kinda just a means to an end." Haimawari said, continuing from before. "The truth is that I just like to help people. Being a licensed Hero is nice, but I did plenty without it."

"Illegally." Shota added pointedly.

"Yeah, yeah." Haimawari waved off the interruption. "But anyways, I talked with Master, and he made me realize that I wouldn't have been able to help so many people without his tutelage. And if I want to help the most people possible myself, then I realized that the best way would be to teach others like he taught me. Well, maybe not exactly like he did. I'd probably get arrested for doing it like that, but…"

'Wait.' Shota stopped in his step as what Haimawari had just said finally sunk in.

But the newly minted Hero continued speaking, an oddly shy tone to his voice. "So, I had him get me in contact with Nezu, and the principal liked my line of reasoning as well, so he decided to offer me a position at U.A. this year."

"What position." Shota asked as he stared blankly forward.

"Umm, as a teaching assistant?" Haimawari answered, looking a bit bashful.

"Assistant to who?" Shota clarified.

Haimawari glanced away, confirming his suspicions. "Y-You…"

Shota took a moment to collect himself. He wouldn't scream. He's more in control than that. However, he allowed himself to bend down and curl up in place for a few moments. Haimawari stood next to him, looking down concerned.

After his quick moment, he stood back up and just kept walking. "Alright."

"That's it?!" Haimawari asked rather surprised.

"Not much I can do. Whining about it would be irrational, and if Nezu approved it then trying to change his will be impossible." Shota let out a sigh. "I guess I'll learn to deal with it. I'm already in charge of twenty one children, what's one more?"

"Oh come on, I'm not that bad-"

They were both cut off as their phones both blared with the activation of a Villain Alert nearby. Shota looked down at the details, and who had already listed themselves as enroute, and immediately put his phone away.

"Shit, this is just a few blocks from the school!" Haimawari said in a panic, turning in the direction the alert had come from. "We should go do something about it!"

"Don't bother. You'll just be wasting your energy." Shota replied, continuing his commute to the gates.

"Huh?!" Haimawari looked at him like he had gone mad. "But an alert this close to the school, and at this time? There are probably students involved, right?"

"I know for a fact that one of my students are involved." Shota said, shaking his head. "Unfortunately for those Villains, said student happens to be a Pro Hero already. And they tend to run into these kinds of issues all the time."

As if on que, there was a loud boom, and both looked out into the distance to see a person with a large mutant Quirk launch into the air. A moment later, someone appeared above them and launched them back towards the ground. Then the figure rocketed back down in a red streak, producing another boom. If one listened closely, they may have heard a faint cry of "Smash!" over the impact. A second later, the alert turned off.

"Whelp, that looks like it's been dealt with. All Might has already sent an enroute message, so no need to worry about cleanup." Shota explained. "We don't have long before class starts, so get moving. If you're late for the first day, I'll expel you."

"You can't expel a TA, Eraser." Haimawari said unimpressed.

"I'll find a way." Shota threatened as the two picked up the pace.

"Alright, we're here." Shota said in front of the door to his class as he pulled out his favorite sleeping bag.

"Umm, what are you doing." Haimawari asked with a raised eyebrow.

Oh, right. Shota wasn't used to having to explain his teaching methods to others. Most of the staff had simply accepted his ways and shrugged it off. U.A. High School is known for its freedom of teaching, after all.

"It's a test to see how attentive future students are, as well as judge their reactions. It works as a good test to see how they will act to other things in the future." Shota explained.

Haimawari looked like he wanted to call bullshit, But after a few moments, he eventually smirked. "Sounds fun. Can I join in?"

Shota shrugged as stepped into his sleeping bag. "Do as you wish."

As Shota lied down on the floor in his sleeping bag, Haimawari activated his Quirk to slide up the wall and onto the ceiling, sliding quietly to the backdoor of the classroom. They both stealthily opened each door to the classroom and entered silently from the floor and ceiling.

Glancing around as he wormed toward the front desk, Shota could see that most were too busy chatting to notice him, or the younger man currently sliding across the ceiling in the back of the room. The only one to notice was Shinso, but only because he was used to such shenanigans after their training. He also noticed that two of the desks were still empty, despite roughly 30 seconds until the bell. The empty seats were of Bakugo Katsuki, first ranked in the Entrance Exam, and Midoriya Izuku, the Hero Deku and up and coming problem child.

With his ear so close to the floor, he could quickly pick up the sound of two frantic pairs of steps approaching his room. A moment later the door slammed open, and two teenagers flung into the room as the rest of the class jumped.

"Excuse me!"

"Fucking move!"

Both missing students practically flew across the room and into their seat only a second before the bell rang. Both of them slumped against their seats and let out as a sigh as they managed to pass Shota's first hurdle successfully. Promising student or not, anyone late for their first class wasn't worth wasting his time.

"That was too god damn close." Bakugo said as he caught his breath.

"Yeah. Maybe we should have saved the chat for after class." Midoriya admitted, glancing towards the front of class. "Huh? Where's-"

Midoriya's eyes trailed down to Shota, and a couple of students picked up on his gaze and spotted him as well. Realizing the gig was up, Shota stood up in his sleeping bag, emerging from it like a butterfly would a cocoon. He stepped up to the podium, ignoring the various looks he was receiving.

"I've been here for a few seconds now. It seems we'll need to work on your special awareness first." Shota grumbled. "I'm your Homeroom teacher, Shoto Aizawa, and class starts now. You've all made it on time fortunately, even if some cut it closer than others."

Midoriya gave him an indignant look as a strangled noise emerged from his throat. "Seriously?! I know you saw that alert-"

"No excuses. Unexpected situations are expected for Heroes to handle." Shota said, and Midoriya crossed his arms as he sunk into his desk. He shifted to the rest of the class, pulling out a stack of gym uniforms. "Everyone, go change into these and meet at the gym grounds."

"Wait, what for?" A pink skinned student asked.

"Aizawa-Sensei! What about the opening ceremony?! Our class will be late if we do not leave within three minutes!" Another student that he easily recognized as Tensei's younger brother declared.

"There's no time for frivolous things. If you want to be a Hero, then you need to give it your all the moment you step foot onto these grounds. You all have ten minutes." Shota declared as he turned to the door. Right as he put his hand on it though, he glanced over his corner with a smirk that he knew caused many to shiver. "Oh, and don't forget to say hello to your T.A. for the year."

"What?" A girl with jacks for earlobes in the back looked around and glanced up when Haimawari let out a huff. "Holy Shit!"

Everyone turned and watched as Haimawari slid across the ceiling to the front of the classroom, before dropping down next to Shota. "Sup!"

"You're The Crawler…" One of the students said with a gasp. There were a few who didn't seem to recognize him. But many of them began muttering in amazement.

"It's Skycrawler now, actually." Haimawari said sheepishly.

"How long were you there?" Shinso asked worriedly.

"Since Aizawa arrived." He answered.

Shinso looked to Shota with a panicked expression, knowing he had failed to detect him at all.

"Here's my first lesson kids. Don't forget to look up." Shots said scarily.

Once all of the students in 1-A were lined up, Shota began to speak.

"Today we'll be doing a Quirk Apprehension Test." He said plainly, and they all began to interrupt at once. He shot them a quick glare with his Quirk, and they quieted down. "I'm sure you've done a set of standardized tests since you started going to kindergarten, but most of you were also likely limited due to not using your Quirk. Mostly cause the education system still doesn't know how to standardize a world with such varying Quirks. But here at U.A., using your Quirk to its utmost is important."

Shota glanced over his shoulder to his new TA, who was standing aimlessly next to him. Might as well make himself useful. "Haimawari, what was your softball pitch in middle school?"

"Huh?" Haimawari took a second to realize he had been called on, quickly trying to answer his superior's question. "Um… It was probably somewhere around 50 meters?"

"How about you show them the difference a well-practiced Quirk can make?" Shota said as he tossed a softball over to him.

Haimawari caught it with an 'oof', before walking to the pitching area. He felt the weight of the softball, tossing it lightly a couple times, before smirking. He finally tossed it high up in the air, as he drew back a fist which had his Quirk's forcefield active on it.

"Knuckle Style!"

The fist connected with the descending softball, and there was a blast of wind as it disappeared. There was a silence among the students as they all glanced around in confusion. There was a beep from the tracker on Shota, and he held it up for all of them to see.

'1000.00 m'

"Holy crap…" Mineta muttered in amazement, much like many others.

"I had no idea the guy was so tough." The student with ear jacks for earlobes said.

"As you can see," Shota began, quieting the students again. "Quirks make a huge difference in determining your true potential. We'll be using these tests to determine the basis you will all be starting from."

At those words, the murmuring turned to full blown excitement. And just as Shota had expected, one of them finally said the magic words.

"This looks like it's so much fun!" The pink-skinned student cheered.

"No, don't say that-" Shinso tried to intervene, but Shota's chuckle interrupted him, causing a deathly quiet on the field.

"Fun, you say? Does fighting Villains seem to be fun to you? What about saving people from disasters? Is that just a game too in your minds?" Shota asked in a mocking voice. "Being a Hero is serious business, and so is this course. To make sure you all aren't slacking off, here's a new rule: The person who gets last overall will be expelled."

The students all mostly turned into pandemonium. The only ones that didn't appear to freak out much was Shinso, who knew Shota enough to see the true purpose of this test and know not to tell anyone, and Midoriya, who seemed to be scheming something. Shota didn't know what, but he decided that it was no good. Before walking away to the first test, he lazily looked over his shoulder.

"Also, just to make this fair. Midoriya, if you don't get first overall, you're also expelled."

"Oh, come on!" Midoriya threw his arms up in frustration as everyone now turned to look at the scarred boy in confusion. Shota knew the boy was trying to keep his Hero identity on the downlow for at least a little while, but he won't make an exception for not going all out in his class.

"Alright now. Let's see how you all do…"

Shota stared down at the results of the Quirk Assessment Test on his tracker device, while the rest of the now exhausted class stood in a line in front of him. He didn't really care about the results of the test, as he was more interested in watching their efforts in creating them. But he still enjoyed watching the class squirm as he pretended to look at who to expel.

As expected, Midoriya had managed to get first place, and had done so almost solely using his basic strengthening, though Shota was able to deduce the use of some other Quirks. He would have to look over Nezu's folder on the boy and figure out what they were. Normally he would make a point of the boy holding back to not expose his identity. But knowing the young Hero, he likely held back to not demoralize the rest of the class. Anymore than he already had, at least.

Going down the list, there was some other impressive results. The Yaoyorozu heir had a good head on her shoulders, using her smarts to produce objects with Creation that set her as an easy second for almost all tasks. He had high hopes for her as a recommendation student, but he won't coddle her either. Heroics has little care for things like her family status.

The other standouts were Bakugou and Todoroki. While he didn't know much about Bakugou other than his apparent closeness to Midoriya and placement in the Entrance Exam, the fiery teenager's boasts were more than just bark. His Quirk was simply yet effective, and he wielded it with incredible precision for someone who likely hadn't received formal training. His dedication was clear and allowed him to climb up the results.

On the other end was Shoto Todoroki. Shota had been informed of the situation behind his family when the son of the number two Hero applied. Honestly, how Midoriya and Nezu managed to cause so much trouble in a single day is truly insane. But anyways, Shota was surprised that the young Todoroki had still applied to become a Hero after the truth of his Father had come out. When Shota had said as much to Nezu, the rat simply said something about the young man wanting to be a 'Proper Hero' for his little brother to look up to.

He went down the rest of the list, mentally going over his observations of each student as he did. Those with Quirks that helped little or not at all to the test had obviously scored low, with the most unfortunate of them being Hagakure, who's Quirk didn't provide a single benefit through the whole trial. But they all still tried their best, which was an unusual rarity these days. Maybe the Rapture made the kids more motivated?

Taking a quick glance to his side, he saw Haimawari looking legitimately nervous, and realized he probably expected him to absolutely expel someone. Shota realized that he had tormented everyone present enough and looked back to the class. He pressed a button on his device, projecting the overall ranking for the class to see.

"Here's the results of the test." Shota said plainly, as the students all looked it over. While he couldn't see Hagakure, he could tell enough from the body language off her clothes that she was shaking. He honestly felt a little bad for her, but she'd need to learn the lesson that most other Heroes and Villains would excel her in physical tasks eventually. Before anyone could say anything about the results, he began speaking again. "By the way, that 'Expulsion' thing was a lie."

Everyone, even Haimawari, stared at him with bug-eyed silence. Eventually, they all opened their mouth at the same time.

"WHAAAAAAAAAT?!"

"It was a logical ruse, to ensure that you all gave it your all." Shota said, a bold-faced lie. It had been a while since he actually had to use this excuse for a class. They might impress him this year. He turned to walk away. "Your curriculum sheets are back in the classroom, so be sure to grab a copy. If you have any questions, go bug Crawler. That's what Nezu hired him for."

"Hey!" Haimawari turned to him somewhat indignantly as Shota walked away casually.

The moment Shota turned the corner around the shadowed side of the building, he pressed his ears to it, leaning towards the way he came. He always found it was important to see how the students acted away from the teachers. Hearing their reactions after such an event would help him judge how to teach each of them in the future.

"Holy crap!" The voice of the laid back and pink-skinned student, Ashido, he had overheard, cried out. "I thought I was toast!"

"Same girl!" Hagakure cried. "I was at the bottom of the list. I thought I was done for…"

"I can't believe a teacher would use such deception on the first day of class!" The younger Iida declared. "It seems incredibly improper to do so!"

"I thought it was obvious it was a ruse?" Yaoyorozu said, clearly shocked by their reactions. "I mean, there's no way a teacher at a school as high standing as U.A. would do such a thing."

"No." Everyone turned to Shinso, who had a scary look on his face. "Eraserhead was the one who trained and sponsored me for the Recommendation Entrance Exam. I can guarantee he was serious about the threat. It wouldn't have been the one in last, but if one of you didn't take this seriously, he would have expelled you without a second thought."

"Seriously dude?" Mineta stared at him in horror, before turning to Haimawari. "H-He's kidding, right?"

"Actually… I checked his file earlier, and Eraserhead has like a hundred expulsions on it. So yeah, I totally expected him to kick one of you out." Haimawari admitted.

As the conversations died of and the class began to leave, Shota set off from the wall, having heard enough. He needed to go finally read the files for his students, now that he knows that they'll all stick around for now. Although maybe he'll take a nap first…

His dreams of a mid-day rest were cut off quickly though, as a massive man in a garish yellow suit blocked his path.

"Ah, Aizawa! I see you still have your class in one piece! See some promise in them?" All Might asked, naturally looming over Shota's hunched posture.

"They just don't have zero potential, that's all." Shota said with a sigh. "Still, throwing that pupil of yours in my class is just asking for trouble. I hope you know I won't be giving him any special treatment, even if he's a popular Hero already."

"I'm sure he wouldn't have it any other way. It was his request to go through class like everyone else, despite his accomplishments." All Might explained. "That said, his experiences do allow for him to provide a valuable insight for his fellow students. And I had an interesting idea for the first Heroics class that I'd like to run by you."

"Hmm…" Shota looked at All Might before shrugging. "Alright then, let's here it. I'm actually rather interested to see if you've come up with something worthwhile."

Next Chapter: Class 1-A & Deku

A/N: And so ends another chapter. The Crawler is back! And back to making Eraserhead's life a living hell. But now we've finally got to actually seeing class 1-A! btw, the Hero Course's composition is the same except for Shinso replacing Uraraka, and taking Shoto's spot as the Recommendation student, as well as Honenuki joining as a regular student. 1-B is also the same, except Inasa replacing Honenuki, and taking his spot as one of the Recommendation Students in 1-B.

There were a couple references to an event that'll happen in a story that hasn't been released yet. But there's probably enough here for most to speculate what happened with the HPSC and Endeavor. Look forward to it.
