The school was filled with loud chattering again at its halls were crowded with new and returning students. After the first year had ended with so much drama and fanfare for class 1-A, they were looking forward to what the future will hold for them now. Uraraka was peering around as she brightened up, hearing a familiar voice scolding some of the new students for their behavior.

"Iida-kun! It's been awhile!" Uraraka exclaimed as she gave the taller boy a tight hug. The first years snickered as Iida lost his composure and had to fumble to keep his glasses from falling off. "U-uraraka-san! It's great to see you again as well! How has your summer been?" Iida asked after he calmed down and returned the hug.

"It was great! My internship went well and I was able to go back home for a bit to visit my parents." Uraraka said before someone else caught her eye as they waved the two over. "Uraraka-chan! Iida-kun!" Tsuyu smiled as she hugged the other girl tightly. "Asui-chan!" Uraraka giggled as the other girl gave her a chaste kiss on the cheek.

They had decided to start dating near the end of their last week before summer started. While they were able to meet for dates and such over the summer, it had been two weeks since they had last seen one another. "Ah, Asui-chan-san. It's good to see you again, have you gotten more muscular?" Iida replied as Tsuyu blushed red.

"Yeah, my internship really worked me to the bone ribbit." Tsuyu responded before the others who were with her greeted Uraraka and Iida. "Hey! No warm welcome for us? I'm hurt." Kaminari cried exaggeratedly as he, Jirou and Mina gave them hugs.

Soon enough, the group had to start moving to class 2-A as they were excited to see who their new homeroom teacher was going to be. They were excited to see Aizawa-sensei's face again, even if the man scared them every now and then. They all knew he cared for them like they were his own children. Sliding open the classroom door, they saw mostly familiar faces.

Their classmates were basically everyone from class 1-A, with the exception of Shinsou who had been able to join the hero course after being trained by Aizawa-sensei after the events at the sports festival. He was currently chilling next to Tokoyami who looked even edgier since last year.

Kirishima was still chatting up Bakugo who had mellowed out a bit more since summer started even though he was still as explosive as ever. Yaoyoruzu was quietly talking to Hagakure and Sero. Ojiro, Shouji, Koda and Sato were relaxing as they opted to keep to themselves. Aoyama was preening in front of his handheld mirror as he noticed them come in.

"Ah! My friends! It's so good to see you again! Bonjour!" He posed as everyone turned to greet them as well. "Hmm, That's strange, Todoroki-kun and Deku aren't here yet?" Uraraka questioned as the sound of the door sliding caught their attention as Todoroki walked in. "Ah. speak of the devil and he appears! Todoroki! My bro!" Kirishima joked as Todoroki gave them all a slight smile.

"Hello everyone it is good to see you again." Todoroki responded before he blushed and looked around the classroom, deflating a bit when he saw that Izuku hadn't arrived yet. "Is-Is Midoriya-kun not here yet?" He asked as everyone shook their heads. "I haven't seen Deku all morning, and that nerd is usually early for this shit." Bakugo responded as the class got a bit concerned.

"You don't think something could have happened to him do you? Ribbit?" Tsuyu asked as Uraraka put a hand on her shoulder to reassure her girlfriend. "Don't worry Asui-chan! This is Izuku we are talking about! He'll probably come strolling in any minute now!" Everyone nodded as they all took a moment to take in their changes.

While most of them haven't changed much physically, a few people got haircuts and changed up their looks a bit. The boys got a bit taller and such. Shinsou was the one to surprisingly speak up, "Do hero classes have some sort of prerequisite of being hot or something?" He chuckled before Bakugo smirked, "You act like you're not a fine piece of ass, shitty zombie." Shinsou blinked before he blushed in embarrassment.

"Shut up.." Shinsou mumbled before he buried his head in his hands. The class quieted down when they heard a familiar voice scold someone in the hallway. "I'M FOURTEEN YEARS YOUR SENIOR THIS SHOULDN'T AFFECT ME SO MUCH." Aizawa yelled in an uncharacteristic moment as everyone looked concerned at the door.

A few seconds later Aizawa had slammed the door open with such force that students had to wince as they covered their ears. When they looked up, they were flabbergasted to see their normally deadpanned teacher wear a deep red blush on his face as the man walked in stiffly. "What the fuck?" Bakugo cursed as everyone peered over to see who caused their teacher to be so flustered.

A smooth, baritone voice called after him, making the class blush simply from the sound. "Ah! I'm sorry Aizawa-sensei but what did I do wrong? I only caught you when you bumped into me!" Everyone's eyes widened as they realized who just walked in, their form towering over their teacher who was rather tall himself.

"No-" "Fucking-" "Way!" "Is that?" "DEKU?!" Everyone screamed as Izuku walked in, looking nothing like the short, cute boy they remembered from last year. Izuku looked taken aback at their extreme reaction as he gave them a smile that blinded them. "Everyone! I'm so happy to see you again!" He said as he slouched down to hug Todoroki who had become froze into a statue.

Izuku used to be short, he used to be lean and awkward and look like you kicked his puppy. This Izuku was tall, with generous amounts of muscle that wasn't too much. His baby face slimmed down and now his jaw showed through in a masculine way. His wide green eyes were still as kind and vibrant as ever, but they were just the slightest bit more hooded now as they stared down at everyone.

He had changed his messy, fluffy hairstyle to a stylish two block cut with a hint of an undercut. Todoroki couldn't handle the proximity of this new Izuku as his eyes spun around and he accidentally burst into flames making Izuku yelp before setting him down and trying to see what was wrong. "Holy crap bro...You-You-" "How did you get so fucking hot Midoriya?" Kirishima was cut off by Kaminari who voiced everyone's opinion.

Izuku tilted his head, making their hearts flutter, before asking, "Eh? What do you mean Sero-kun? I know I got a lot taller but I didn't do anything other than training?" "Un-fucking-believable. Of all people to have a shocking image change why did it have to be you? Damn nerd?" Bakugo groaned as he covered his face with his sweaty hands.

Aizawa sighed before telling everyone to quiet down and get to their seats. No one could take their eyes off of Izuku though, as the boy? Man? Seemed to radiate from where he went to sit down. "I don't understand? It's not possible to just suddenly shoot up from 5' 5 all the way to like 6' 7 is there?" Yaoyozuru muttered as the others near her questioned that as well.

Shinsou was turning fucking purple as his eyes were drawn to Izuku's broad, muscular back that led down to a wickedly great ass. "Holy fuck, thank the lord." He prayed as everyone gave him glaring looks. Todoroki looked like he was literally about to kill the boy with his eyes. Izuku couldn't help but feel a bit awkward as he started sweating from having everyone's attention on him.

Strangely, everyone he walked past this morning reacted the same way. In fact, he remembers Mirio becoming more flustered around him as well after Izuku had grown tall enough to look down at the older boy. The people on the subway crowded around him and he swore at least two people pinched his butt, although he wanted to think that was an accident.

He was approached by some modeling agency recruiters that looked so regretful as he turned down their offers, stating that he didn't think he was model worthy. When he asked All Might and Nighteye what was going on, the two men only shared an amused look before telling him it was all a process of growing up.

Izuku sighed as he loosened his tied and popped a few tight buttons before running a hand through his hair as he tried to get his mind off of the topic. He didn't realize how everyone focused in on his small actions like vultures as several simultaneous gulps sounded. Sero had nervously bumped his elbow into his desk, making a few of his writing supplies fall off as he let out a soft curse.

Just as he reached down to get them, Izuku's larger, scarred hand had already picked them up as Sero drooled at the sight up Izuku's biceps and slight peek at his chest. "Here you go Sero-kun, be careful ok?" Izuku told him as the green haired boy gave Sero a direct attack with his charming smile.

Bakugo and Shinsou had reacted at the same time to send their stuff flying down at Izuku's feet as the freckled boy looked at them confused. "E-eh?" He didn't really question it as he reached over and picked up their stuff as well. "So I see everyone has survived and made it to their second year at U.A. I would be disappointed if that wasn't the case." Aizawa-sensei told them as he rolled his eyes at their fixation on Midoriya.

Honestly, he could understand why they were so flustered, he himself was startled just now in the hallway. He hadn't notice Midoriya in front of him as he bumped into the muscular chest and stumbled backward. A warm, gentle hand, larger than his own and textured by the scars he had gathered since last year, caught him by the waist.

He didn't expect for Midoriya's stupidly handsome and still innocent face to be so close to his as his heart thumped for a second and he had to take a few moments to realize who Midoriya was. 'Even though I'm dating Hizashi, Midoriya is not good for anyone's heart. I'm actually excited to see Hizashi's reaction to one of his favorite students' new look.' Aizawa chuckled as he could imagine the shocked expression on the blond's face.

The class roared with excitement as they welcome Aizawa back with open arms. "Now that you are all second years, things are only going to get both easier and harder for you as you strive to become great pro-heroes! Some of you still need to get your license while others need to improve their social standing out in the world. I'm honored to be your teacher once again. Go beyond!" Aizawa declared as the class finished for him.

"PLUS-ULTRA!"

Notes:

I always wanted to read a fic like this after finding some awesome grown-up Izuku fanart, but I'm not actually sure if there are any. Please link them if you can find some! Haha! Also, feel free to help me determine future pairings and maybe ask for some interactions you would like to see me write. While this isn't a request or drabble fic, I really like reading everyone's comments and creative ideas XD

Also yes, Mineta does not exist in this fic B).
