Aight, I've been dying to write some Assassination Classroom/My Hero Academia stuff for a long time now. I've had so many ideas, and I figured it was about time to write one up. These two animes are just so fun that I couldn't help but think about all the crazy stuff that could go down if they came together. This is one of my ideas. Oh also, credit to my friend VODweiler for the title idea when I was struggling. Anyway, I hope you'll enjoy this chapter, and there is a little spoiler warning below that I'd suggest you read if you haven't caught up with one or both series. There will be more spoilers throughout the story, but I'll be sure to put a spoiler warning at the start of each chapter just in case.

Spoiler warining: This story will contain spoilers for the follow Assassination Classroom episodes: Action Time, Pandemonium Time, Karma Time/2nd Period, XX Time, and Nagisa Time. It will also contain spoilers for the following My Hero Academia episodes: Game Over and All Might. If you haven't watched any of these episodes yet, I'd advise you to wait on reading this story until you've done so if you want to avoid spoilers.

Disclaimer: I do not own BNHA or Assassination Classroom.

Izuku cast a worried glance over his shoulder back at the area where All Might was holding off the villains as he trudged along with Asui and Mineta, their injured teacher supported on their shoulders. He could hardly see a thing over Aizawa, but the rushes of wind from the powerful blows could still be felt. All Might's strong smashes could be heard, too, along with the horrible screeches of that monster.

He wasn't worried that All Might couldn't save them; he was worried what it would cost All Might to save the class. Would he have to use up everything he had to save them? Or would he have to sacrifice himself to keep them from harm?

"Thanks for telling me how to beat him!" the Symbol of Peace's voice echoed. "If all I have to do is wear him down, then it's on to you!" A yell of pain and a noise like an explosion rang out, making the green haired boy pause for a moment to look back out of fear for his teacher.

They were met with an approaching cloud of darkness, like the one that had separated them from the others at the entrance of the USJ. "Asui! Mineta! Look ou-" was all Izuku managed to shout before they were swallowed by the shadows.

"Alright, that's enough. Class dismissed," Karasuma said, coming up behind Karma and taking Korosensei, now in ultimate defense, from his hand, ending the redhead's fun. "For this one, I think we'll let HQ decide the best course of action," he continued, slipping Korosensei into a small plastic bag with ties that doubled as handles.

The octopus gave his typical creepy giggle, turning his broad smile up to Karasuma with his beady eyes full of smugness. "Your superiors will opt to toss me into a pool of anti-me liquid, I'm sure. Good luck with that! The energy displacement would explode as it did earlier. Everything in the vicinity would be blown sky high, including your superiors!"

Karasuma narrowed his eyes and growled lowly with frustration. The students looked down dejectedly at the waves or the boards of the dock as the power of the absolute defense form sunk in.

"Still, you should be proud, boys and girls," Korosensei went on reassuringly. "Entire armies, the world over, couldn't get as close to killing me as you've done tonight. This was, by far, the cleverest assassination attempt I've ever encountered!" His cheshire smile grew bigger, showing his pride in his students, though his words didn't seem to have much effect on upping the morale.

Most students remained floating in the water, too disheartened to even lift their gaze. Chiba and Hayami in particular seemed to be affected most likely due to their crucial roles in the whole scheme.

The students began making their way to the dock, all of them downtrodden and worn out. No one seemed to be in high spirits despite Korosensei's speech. As 3-E plodded along in silence, the heavy mood was broken by the sudden appearance of a dark, shadowy cloud above the beach just to the left of the dock.

Everyone, even Korosensei, seemed bewildered and surprised by the shady mass. The group looked on tensely and waited for something to happen. Just as suddenly as it had appeared, the shadow exploded. Various cries and shouts of surprise came from the students as it dispersed, making it impossible to see. "What the hell?!" Karasuma shouted, shielding himself with his arms and weathering the fierce winds from the cloud.

After a moment, the winds ceased and the murky shade disappeared. Everyone looked around, guard up and ready to fight at a moment's notice. The sound of coughing from the beach caught everyone's attention. There were three kids, all dressed in rather odd looking costumes, sprawled out on the beach. The one with the messy head of dark green hair was the source of the coughing.

"Midoriya, are you alright? Mineta, what about you?" a croaky voice asked, though it was hard to hear from where E class was standing. Both boys answered her, but none could make out what they said. Either way, all three seemed to be fine as they picked themselves up off the ground.

Irina leaned over to Karasuma and whispered, "What should we do? Not that I want more snot nosed punks to look after, but it'd be stupid to just leave them there after the entrance they made."

He nodded. Not only would it be irresponsible to leave a few kids to their own devices on an island, but they also didn't seem to be normal if the way they arrived was anything to go off of. He'd have to be careful about this. Karasuma cleared his throat and called out, "Hey! Are you kids alright?" If he hadn't been teaching, the word 'kids' may not have rolled off his tongue as easily.

The group of three turned to the voice, slightly startled. It was then that they noticed the large body of students on the dock next to them. "Uh- Yeah, we're okay," the boy with messy, dark green hair replied loudly so that he could hear.

"Stay here," Karasuma commanded, handing Korosensei over to Ms. Bitch. "I'll go down and talk to them. If they seem like a threat or make any move to attack, you get the students away from here and call for backup." He was already halfway down the steps before she could protest.

As the man approached them, they seemed to be on guard with the boy and girl tensing while the shortest of them took a step back nervously. Upon seeing this, Karasuma paused. "Don't worry, I just want to know your names. I don't have any intention of harming you. The name's Karasuma, by the way," he added, hoping that would help the group loosen their guard.

A short silence followed before the girl stepped forward. "My name is Tsuyu Asui," she introduced with a bow. She turned her large eyes to Midoriya and Mineta, flashing a quick glance at Karasuma.

He got her message and followed her lead. "I-Izuku Midoriya."

Mineta looked at both with uncertainty before he reluctantly said, "Minoru Mineta."

"If you don't mind me asking, why're you here?" Karasuma continued. Of course he was curious about how but that could wait until they were in a more private place.

"Um, sir, where are we, exactly?" Asui asked, one hand near her mouth with the finger lightly touching her cheek as if she were thinking and the other hand held up slightly near her waist.

He quirked a brow at her question but answered her anyway, "Okinawa Island, Japan."

"Okinawa Island?!" Mineta yelled so loud that even the students on the dock winced. The short boy gripped the sides of his head, panicking. "Ah, what're we gonna do?! How're we gonna get back?!"

"Mineta, calm down," Midoriya said, hoping to calm the smaller boy down. "We'll find a way back, but we should probably look for our teachers or classmates. There's a chance they're here too."

"Would you mind waiting until morning?" Karasuma spoke up, gaining their attention again after Mineta's outburst. "We could help you find your teachers tomorrow if you aren't in a rush." He threw a glance over his shoulder at his students.

The three stared at him, surprised by the sudden offer. "Uh, I guess we can wait," Tsu said slowly. They didn't have many options. It was late at night, meaning most pro heroes wouldn't be out and about like during the day, not unless they were a night based hero. On an island like Okinawa, the chances of there being a pro that worked on a schedule like that was unlikely at best.

Karasuma hummed, nodding his head. "Alright then. You three will come back to the resort with my class and stay until morning. Then we'll try to locate your teachers and any other students from your class."

"Yes sir," the three said together.

With everything settled, Karasuma made his way back to the dock with the three following behind him. Once they reached the others, Karasuma began to speak again, this time to the body of students, "Alright, I know today's been eventful, but tomorrow morning we're going to help these three find their classmates or teachers. Got it?"

"Yes sir," the group of assassins said tiredly, too worn out to complain. Besides, they knew there was no point in arguing with Karasuma. After hearing confirmation, the group began the walk to the resort.

Once they had arrived, the students, including Midoriya, Asui, and Mineta, went out to one of the porches of the resort and sat around the tables while Karasuma informed the resort of the new guests and the ministry of Korosensei's new ability.

Izuku sat rather awkwardly by a red-headed boy with a bluenette sitting opposite of them while Tsu and Mineta sat nearby at a table with a few other girls. He was too absorbed in his thoughts to really notice either one. Aside from a few whispers being shared between students, the walk over had been quiet. A few of the students also gave Mineta some odd glances, but the short boy had been too wrapped up with his own nerves to notice. But what had really caught his attention was the small smiling ball held by the blonde woman. He had made a mental note to ask about his Quirk the next day.

"Hey, can you quit that muttering?" the red-head beside him said, nudging him with his elbow while he twirled a straw in his mouth.

The green-haired boy snapped out of his thoughts with a small yelp, covering his mouth with both hands after realizing he had been muttering again. "R-right, sorry," he muttered, his voice muffled behind his hands.

His overreaction earned a bit of a smile from the bluenette sitting across from him, but nothing more than that. A student with long bangs that obscured his face and a beanie pulled out his phone, "Ritsu."

A feminine voice from the phone answered him, "Hi, Ryu."

"You recorded it, right?" Now Midoriya's interest was piqued. Recorded what?

"As faithfully as possible utilizing high speed camera filters whenever they seemed appropriate," the voice from the chirped cheerfully. "Would you like to see?"

The boy, who Miodoriya had guessed was named Ryu, was silent for a moment. "The second I fired, a part of me knew the bullet wouldn't hit. It was like… I knew he couldn't be killed." Izuku's already large eyes widened considerably at his words as he listened more intently and made sure his hands were clamped over his mouth tight to prevent any more mumbling. Who were they talking about and why were they trying to kill him? Heroes didn't have authority to kill, except under specific circumstances, and students training to become pros certainly didn't have that authority. From what he could tell, most of them looked like middle school, maybe high school age, so there was no way they had authority to kill someone.

There was quiet buzz from his phone before the voice of Ritsu spoke again, "I can only be approximate. The time it took for Korosensei to adopt his absolute defense form is unclear. However, by my calculations, if your shot had been point-five seconds faster or Hayami's thirty centimeters to the left, our odds of target neutralization would have increased by fifty percent minimum." So Koro Sensei was the one they were trying to kill… But he still didn't have any answers as to why. And the more he thought, the more questions arose. Where was Korosensei? How did escape an entire group? Why were they talking about it in the open?

A girl with orange-brown hair in low pigtails, who Midoriya assumed was Hayami, lowered her head a bit.

"The whole thing was so easy in rehearsal. I was so sure of myself. I even fired from a less stable spot and totally nailed it," the boy said. He lifted up his right hand, showing his shaking pointer finger, "But when it was real, I froze. It's like my finger were all stiff and my vision was blurry."

"Yeah, same here," said Hayami, her arm now clutching her shoulder.

"I just… caved under the pressure, y'know? Too much was riding on me making the shot," he went on.

"The moment of truth was nothing like what we practiced," Hayami said, disappointment evident in her voice.

"What the heck are you talking about?!" Mineta finally yelled, unable to take the talk of killing. Midoriya had been so caught up in his thoughts that he didn't even think the conversation could send the small boy into another panic. The other kids hadn't even considered the presence of the other three when talking.

A boy, Maehara, with short, orange-brown hair answered rather tiredly, "Can you not yell? I feel like I could sleep for a week." His face was flushed and he could hardly lift his head from the table.

"I vote we go up to our rooms and crash," another boy at the same table said. "I'm too tired to do anything." He let his head fall back into his arms on the table.

"You're just gonna call it a night?" Terasaka asked incredulously "We did what we're supposed to. What do you want?" So they were supposed to kill him… That only added more to the growing pile of questions Midoriya had. "Granted, the octopus is still kicking, but we're on a primo-vacation either way," he pointed out.

"Truth, man!" another boy, this time with a buzzcut, agreed, pulling his eyes open wide with his thumbs and forefingers. His face looked flushed as well, but other than that, he seemed alright. It was only when he sat back in his chair that the green-haired boy noticed his shirt, which had an image of a woman wearing a short dress that seemed to cling to her figure. "I'm gonna spend tomorrow oggling at gorgeous babes. Just give me a few hours in the sack, and ladies, here I come!" he went on, thrilled by the idea. Looks like Mineta had a kindred spirit.

The boy from earlier sighed, keeping his head just a bit above the table, "It's all I can do to keep my head up."

"Something's wrong," Izuku muttered, loosening his grip on his mouth so that he could be heard. The bluenette in front of him seemed to notice after a moment as well, seeing a handful of students struggling to keep their heads up.

The bluenette stood from his seat, bumping into a blonde girl right by him. "Hey, do me a favor?" she said, her voice shaky and thick. Her face was flushed like many of the others and sweat dripped down her cheeks. "Can I lean on you for a second? I don't feel good…" The blonde's voice trailed off as she collapsed to the floor.

"Oh no, Nakamura!" the bluenette cried, crouching down next to the girl. Midoriya was right behind him, hopping up from his seat and at her side just a second later.

The blonde, now named Nakamura, cracked an eye open to look up at the two. "Oh… Oh, awkward. Sorry, I just wanted to go to the room," she said faintly. "Looks like my body has other ideas, huh."

The bluenette placed his hand on her forehead and gasped, "You're burning up!"

The boy with the buzzcut spoke up again. "Thinking about the hotties is making my nose bleed. That's new-" He was cut off as blood poured out of his nose and dripped down his wrist.

"Okajima!" the bluenette said, turning away from the blonde for a moment. After Okajima, several others slipped out of their chairs and fell to the floor. The others were quick to help and check on their fellow classmates.

Karasuma ran out to the porch and stopped to take in the sight. A few students were on the ground while others were being supported by another classmate. Some appeared to have passed out in their chairs. And several were barely conscious in their seats. Whatever was happening, it wasn't good.

A nice place to leave off, right? Though most of you know where this is gonna go. But let's see how our heroes fare in this situation and maybe how they turn the tides. It's sure to be interesting. Anyway, I'll hopefully update soon. Until next time.
