Chapter 1: Curiosity killed the Shota

"Umm, anyone going to open it?" Mineta asked after five minutes of silence.

"Because this isn't suspicious at all" Jiro stated dryly, not even looking towards him. "What makes you think opening it would be a smart idea?"

Mineta huffed. "It was just a question, geez"

Momo sighed and walked closer to the box. "It doesn't look too dangerous, but we should still treat it with caution." She looked around. "One of us should find a teacher. While it may be an ordinary package, it doesn't hurt to double-check.

Before anyone could volunteer, Iida came barreling through the crowd. He scanned past the faces of some of his classmates until his eyes landed on what had everyone's attention. It wasn't much to look at. An old plain-looking wooden box stood just outside the classroom door.

"What is the meaning of this?" Iida asked arrogantly. "Why are you all wasting time?"

But before anyone could answer...

"What the fuck are you extras doing?!" a voice yelled from behind them. Everyone turned and saw a blond-haired, red-eyed boy.

Marching forward, he pushed everyone else out his way and was going to kick the box through the threshold, but Iida snatched the box right before it could connect, thanks to his speed.

"You have no right to destroy property that does not belong to you." Iida glared. "It was most likely left here for the teacher and I'm positive he would not appreciate you kicking it."

Walking into the classroom and putting it on the desk, he turned to the door with a questioning look on his face.

"Are you all just going to waste time blocking the entrance?"

At that, everyone in the crowd besides Bakugo started to walk into the classroom and find their seats.

"YOU FUCKING EXTRA!" Bakugo stalked towards Ida. "Talk to me like you're better than me again and I'll kill you!"

At this Iida looked genuinely shocked. "You'd threaten your own classmate? Yet, you're here in the hero program" I can't believe it, someone with an attitude like his was allowed into the hero course. He was about to speak again but was distracted when his eyes caught sight of green hair in the doorway. Turning away from Bakugo, he headed straight towards the door.

(Earlier that day)

"Izuku?" Inko asked.

"Ugh, what? I don't want to be late" Izuku sighed.

Tears forming in her eyes, Inko smiled. "It's just I- I'm so proud of you son" Izuku let out a small gasp and smiled.

'That day I began my high school career. The acceptance rate that year was just as small as it always had been. 1/300 were accepted. 4 students go in on recommendations and the other 36 through the normal exam. We were split into two classes of 20 students each.' Izuku narrated.

Izuku walks down the school halls searching for his new classroom. As he finds the classroom and arrives at the surprisingly large door, he thinks about the strength and promise of his new classmate.

He remembers Bakugo and Iida. "M- Maybe we're in different classes." Izuku hoped.

He opened the door

"YOU FUCKING EXTRA! TALK TO ME LIKE THAT AGAIN AND I'LL KILL YOU"

"You'd threaten your own classmate? Yet, you're here in the hero program." At this point, they both noticed Izuku in the doorway.

"Umm, Hi," a nervous Izuku said.

"Good morning! My name is Tenya Iida, I am from-"

"Somei, I heard!" He interrupted. "I am Izuku Midoriya, It's nice to meet you Iida"

"Midoriya, You realized there was more to the practical exam, didn't you? You must be extremely perceptive." Turning his head in shame he continued. "I hate to admit it, but you are far superior to me"

'Yeah, I didn't realize anything', Izuku thought sweatdropping.

"Hey! I recognize that hair, you're the plain-looking one!" Ochako exclaimed.

'Oh wow! It's the nice girl from the exam! She looks good in that uniform.' Izuku thought while watching her make punching motions.

"I suppose I should say thank you for talking to Present Mic" Izuku stammered, blushing bright red.

Confused, Ochako stopped jumping around. "Huh? How'd you know about that?"

"Oh, uhh-"

"What do you think we're doing today? You know, besides orientation? I wonder what our teachers like. I can't wait to meet everyone!" Ochako exclaimed while Izuku hid his blushing face.

"If you're just here to make friends, then you can pack up your stuff now," Aizawa spoke.

Izuku, Ochako, and Iida all look out the door and see him lying on the floor in a sleeping bag.

"Welcome to UA's hero course." He said before taking out a juice box and drinking it.

The three students looked on in terror at the man. 'What is that thing?' They thought.

"It took 8 minutes for you all to shut up." He stepped out of the sleeping back. "Time is limited and you kids are not rational enough."

'Who is this guy? If he's here then he must be a pro, but I've never seen one look so tired.' Thought Izuku.

"I'm your homeroom teacher, Shota Aizawa, it's nice to meet you."

'Our teacher?!' Izuku asked mentally.

Just as he was going to tell them to change their clothes and head outside, he noticed the wooden box that lay forgotten on the desk.

"What is that?" he asked dryly.

Mentally Shota groaned when no one answered him. Either someone was stupid enough to try and prank him, or someone was being a kiss ass. Neither option was too appealing.

"I asked you all a question"

Momo stood up. "Hello. My name is Momo Yaoyorozu, sir. We do not know what the box contains or who it belongs to. It was in the doorway when most of us arrived."

"I see." He sighed.

'I've never gotten a package sent to the school even once. I was not expecting a package. This could be a prank, but why chance it?' Aizawa thought.

"Everyone get up and stand near the door."

Slowly, they all got up and moved towards the door. They didn't go too far out because they wanted to see what he was going to do.

"I'm going to open this box, if it's a prank that any one of you thought would be funny, I will expel the entire class," Aizawa stated, never looking away from the box. "So, if anyone wants to come clean beforehand, then we can do away with this and get back to business"

No one moved.

"Okay then," He reached for the lid.

The moment his fingers touched the box everything froze. Although he could still move his eyes, Aizawa could not move the rest of his body. This prevented him from seeing that all of his students were in the same predicament.

'W- What's going on? My body…. It won't move" Izuku thought, straining every muscle in his body in an attempt to get even one limb to move.

Moving his eyes to look around, Izuku could see that all of his fellow students were frozen too. It was at this moment that he realized that he had to do something. He couldn't just wait around for whatever was about to happen.

This is when he got the idea to try out one-for-all. Closing his eyes and taking a deep breath he began to power up. He could feel it coursing through his body.

Sparks flew.

'Oh man, this is gonna hurt' Izuku mentally stated.

As soon as the last syllable escaped his thoughts, he focused one-for-all throughout his entire body and pushed!

A flash of light followed the sounds of an explosion.

At this moment, one word went through the minds of every last person in the classroom.

'Shit!'
