    Summary

    Jaune Arc getting into Beacon caused quite a stir among his family. So a few members decide to check in with the young would-be Huntsman. And given the Arc virility? There are a lot of them.

    Multicross. Comedy (mostly). Taking suggestions for other crossovers and using my usual fan-canon for RWBY.

    Summary

    Midoriya Izuku just wanted to escape Bakugou's bullying and achieve his dream of attending the prestigious UA. He assumed the cutthroat Kunugigaoka Junior High would prepare him for that. Too bad he was immediately booted to class 3-E for being quirkless.

    Shinsou Hitoshi planned for his time at Kunugigaoka Junior High to be spent under the radar. He kept his grades average and interactions with others minimal. But when an incident occurs that requires him to use his quirk at school unauthorized (even though he did it to help another student), he finds himself suspended and, even worse, in E-class.

    When the moon exploded due to the dangerous villain known as the Tentacle, the last thing anyone expected was for him to want to teach 3-E. Now Izuku, Hitoshi and their classmates are expected to become assassins, kill the number one villain, and save the earth from the same fate.

    Summary

    What if things in the Assassination Classroom society were just a little worse? What if every school had an E class and getting booted there really was a death sentence for a child's future? What would a responsible teacher do in that situation? Would they let their kids be doomed to lives of meaningless poverty? Or would they encourage them to go for a more lucrative career?

    Summary

    Nagisa shouldn't be playing this game, he'd already played a deadlier one before, why start a new one? He should've just killed his teacher from the start of the get-go and made things easier for everyone and for Earth at the cost of his identity as a normal person.

    Maybe it was for that he didn't try and kill Koro-sensei so soon. His new teacher's personality and talent in teaching was convincing him to further play this game of normality- however normal an Assassination Classroom was.

    He still missed Gakushuu and Norita though, even with E-Class bizarre dynamic and friendly vibe. But he knew they had complicated feelings about each other, especially after what he'd done to...

    At any rate, Nagisa felt like he could deal with Koro-sensei and save the Earth. He'd done it once before, he could do it again.

    He didn't have to be the Rogue of Rage in E-Class. The Game was over and he was just Nagisa again and hopefully that would be enough.

    Summary

    In the early days, pre-existance of the assassination classroom, Nagisa establishes an unlikely friendship with yet another A-Class big wig by chance - but, having been hurt by the recent friendship break from Karma, Nagisa feels like it may end up as "superficial" as the last friendship he made.

    but, of course, once they begin to connect, as curiosity strings them farther and farther along, the two find themselves more similar than different. in the end, even if Gakushuu is supposed to hate Nagisa for simply being in class E... he can't. he still makes time, using any methods he can to keep in touch.

    even if he has to fight with Karma more than he wants to.

    even if it means going against the explicit rules his father sets for him.

    even if the stress of being a prized student atop this secret is surely eating him alive.

    even if that stress is causing him to black out more and more...

    Summary

    One ordinary afternoon, Class E vanishes.
    Koro-sensei, Karasuma, Irina, and their students wake up in a world where powers are reality, and heroes walk the streets.

    Out of place, outmatched, and under the watchful eyes of Japan’s top heroes, the students must navigate a society that is both fascinating and dangerous.
    One student is chosen to enter U.A. High — a school of heroes, where every move is a test, and every action has a consequence.

    But the more they explore this world, the clearer it becomes:
    their arrival was no accident. Something — or someone — brought them here.
    And what waits for them may change not just their lives, but the fate of two worlds.

While the others underestimate the runt of the class, he perfects the art of provoking Karma - that arrogant alpha who should dominate him, but in reality lives obsessed with his every move.

    Tags
    Summary

    'The End Class didn't understand Karma and Nagisa's relationship.

    Where Nagisa was soft smiles and hesitance, Karma was smirks and forcefulness. While Nagisa offered quiet insights and conversation, Karma provided lazy taunts and razor-sharp wit. Every detail of the two individuals, down to the colours of their hair, was in complete contrast with the other.

    They were polar opposites, and he failed to understand why Nagisa considered him a friend.'

    ---

    In which the End Class finds themselves confused as to why Nagisa and Karma are friends and we get the real reason why Karma calls Nagisa "Nagisa-kun".

    Summary

    Studying for finals is hard. Staging an assassination against an unkillable target is impossible. Even worse? Attempting it all whilst carrying your best friend's baby, of which you barely even remember... well, creating. Nagisa didn't know how his life had ended up like this.

    (Also known as the fic where Nagisa gets knocked up through an unlikely turn of events, Karma doesn't know how to deal with it, and the author has no idea what they'd have done if they didn't end up becoming literal billionaires)
