Author's Note: Two schools. Heroes and Assassins. Why wouldn't I be interested in making a crossover between two amazing anime series?
"Nagisa-senpai?" Shota Nagisa turned to the voice's owner, a green-haired boy who was slightly taller than him.
"Izuku-san?"
"Like I said, you can just call me Deku like everyone else. I don't mind." Midoriya Izuku walked up next to Nagisa on UA's very rooftop.
"Looking at the stars?"
"Yeah. Looking at the unending vastness of the night sky, and the many stars always brings me peace."
"Totally get how you feel." Deku said as he took the spot on Nagisa's right, plopping his arm on the balcony.
The two stood in companionable silence for a while, before Deku asked the next question. "I hope you enjoyed your stay in UA? I understand it can be quite overwhelming, especially with Kacchan around…" he said, sweatdropping.
"Oh? Mmm, I did. It was really very interesting to see what pro-Heroes in training did at school. I think if we weren't already a class of assassins-in-training, we would be very envious." Nagisa smiled, giving his sincere response.
Deku smiled and shook his head. "It still amazes me that you lot are Assassins. Despite the fact that you have no Quirks at all...you all are still so daring and gutsy. It honestly reminds us of how, despite our Quirks...one of the most important parts of being Heroes is courage."
"That's true." Nagisa agreed, nodding. "Courage to face whatever obstacles there are before you, whether Villains or Targets."
Since learning the existence of pro-Heroes with special abilities called Quirks, Korosensei immediately arranged a class exchange between Class 1-A of UA and Class 3-E of Kunugigaoka High. The exchange would last for 3 days and two nights, where Class 3-E would stay in the same dorms as Class 1-A. Despite being a supposed super being able to move at Mach 20 speeds and destroy half the moon, Korosensei couldn't stop making a fool of himself in front of the sweatdropping pro-Heroes at UA like All Might, Eraser Head and Endeavour.

"NYUYAAAAHHH! It's All Might! And Endeavour! I'm such big fans of you! Can I have your autograph, please? Can I treat you to my favourite sweets? Can we hang out for the rest of the day?!..."
"What's with this guy?" "Is he really the guy who destroyed the moon? Seems more like a child-man…"
.
.
.
Izuku and Nagisa, who were both there when the exchange happened, along with the rest of their classmates, sweatdropped profusely as they recalled the exchange.
"Korosensei...sure was lively, huh?" Deku said.
Nagisa nodded. "You have no idea."
"However...I'm really glad I got to know you guys. I'm only in UA because All Might passed on One For All to me. Had he not, I would have been Quirkless like you all. But seeing you all master so many things, despite your lack of Quirks...it was truly humbling." Deku said, smiling at Nagisa.
"I'm glad to hear that." Nagisa returned the smile. "I'm so glad that our classes got along so well."
Initially, the 3-E students had been wary of Class 1-A, but Class 1-A (with the exception of Bakugo) had been surprisingly friendly and welcoming to them. It was an overwhelmingly lovely exchange as the 3-E students demonstrated their knife skills, shooting and assassination skills to the starstruck 1-A students. In return, the 3-E students couldn't stop being amazed by their various Quirks.
Deku ang Nagisa had gotten to know each other, quite predictably, through trying to mediate conflict between their two best friends. I mean, with an arrogant hothead like Bakugo, and a cocky sadist like Karma, what did you think was gonna happen?
.
.
.
"Huh? You're going to be a hero? What kind, the one that kills people and everyone shouts 'Boo' at?"
"EHHH?! What was that?! C'mere and let me kill you!"
"Calm down, Kacchan!" Deku gasped and he and Iida struggled to restrain a berserk Bakugo, whose veins were popping into his head.
"Kill me? Wow, thanks for proving my point. It's a real mystery how you haven't been expelled from here yet." Karma said, grinning cockily.
"Karma-kun, you really should stop…" Nagisa said behind him halfheartedly, while Sugino and Maehara were sweatdropping uneasily.
.
.
.
Nothing like two migraine-causing friends to bring two ppl from different schools together.
But overall, the interactions between the two classes went well.
"You seem like a competent Class President, Isogai-senpai. Please teach me your ways!" Iida said, bowing way more than 45 degrees.
"Huh?! C-c-c'mon, Iida-kun, please don't be like that!" Isogai said, sweatdropping and chuckling.

"Senpai, let's do our best to snatch a picture of the girls' boobs!" Mineta declared, his fist pumping passionately.
"F-f-finally! A man after my own heart! I'm so touched!" Okajima cried tears of joy. Unfortunately…
"You will do no such thing!" Kataoka stood behind them with her arms crossed, tick marks all over her face.
"Kataoka-senpai, here's a sledgehammer to crush them." Yaoyorozu stood next to her with an equally disapproving expression, carrying a huge sledgehammer on her shoulder.
"YEEEEEEEKKKK!" The two perverts screamed in fright.
.
.
.
"Wow!" "Awesome!" Yada, Kurahashi, Kayano, Kanzaki, Nakamura and Okano all exclaimed as Uraraka made them all float with her Zero Gravity Quirk. Even Hayami, the tsundere, couldn't help smiling broadly.
.
.
.
"You got us, Tsuyu-chan." Nakamura sighed alongside Yada and Hayami, as they found Tsuyu holding their weapons in her hands and in her very, very long tongue triumphantly.
.

"Your assassination skills are really something else. Maybe we Heroes might need your help to overcome Villains." Tokoyami said in his usual serious tone.
"We're not sure we want to be professional Assassins…" Maehara said with a weak smile, both him and Isogai sweatdropping.
"However…" They turned to look at Chiba, whose eyes were hidden underneath his bangs as usual.
"If the Villains really do prove to be too dangerous to society...maybe...it's something to consider." Chiba said thoughtfully, his hand cupping his mouth, while Isogai and Maehara looked on with their mouths slightly open in shock. Chiba... had a point.
"I agree." Todoroki, who was standing next to Tokoyami, said. "I usually like to work alone. However...I've realised that there's no shame in relying on my comrades for help. Even if they aren't Heroes." He said with a small smile.
"That's right." Maehara said, as he, Isogai and Chiba all smiled as well.
.

"Hey, Deku?" Deku looked at Nagisa. "Yes?"
"Do you...really think that we should become Assassins? To help y'all combat Villains?" Nagisa asked, his voice almost becoming a whisper at the end.
There was a long silence, where Nagisa swallowed silently, glancing nervously at Deku's hidden face. There was a part of Nagisa that felt like he didn't want to be a professional Assassin. But there was another part of him that wanted to. That felt like being an Assassin was the only thing he was truly proficient at. What if the only profession fit for him was being an Assassin? But he didn't want to be defined as a killer.
"I think…" Deku began, which startled Nagisa out of his reverie.
"That whether you want to become an Assassin is entirely up to you. No matter how good you are at assassination skills, no one wants to be defined as a killer and a murderer. And even if you can't help us as an Assassin...no one said you were obligated to. Also…" Deku turned and smiled brightly at Nagisa. "...There are many other ways to help us."
Nagisa stared at Deku, his eyes gleaming, before smiling. "That's true. Thanks so much, Deku-kun."
"It's nothing, Nagisa-senpai." Deku laughed, scratching his head in embarrassment.
"Call me Nagisa." Surprised, Deku looked at Nagisa, who smiled sincerely back at him.
"Sure...Nagisa."
When they had finished looking at the stars and were going to split up into their respective dorms, Deku held out his hand, and Nagisa shook it.
"When I become a pro-Hero, I look forward to meeting you again, Nagisa."
"Likewise, Deku."
