    This story was previously on my other account (@XvoidskyeX) However, for organizational purposes, I have moved it here. Assassination is the art of structured murder. The target is a monster who blew up the moon and is going for Earth next. It's up to class 3-E to kill him. With the watchful eye of Akane Iroha, they might just pull it off. Let's figure it out, right? Welcome to our Assassination Classroom! Warning: Contains an oc.

Spy X Family The Pet Girl of Sakurasou Classroom of the Elite Seraph of the End My Hero Academia Sword Art Online (Yes, I realize this is ridiculous. Bare with me.) (Author's note gives more detail | not spoilers) --------------- Michaela Hyakuya has been through it-he was abandoned by his parents, kidnapped by vampires, used as a food source, watched all but one of his siblings be murdered as he bled out, was kissed by a grown woman as he was dying without his consent at the age of ten, was turned into a vampire, went through grueling training, helped kill all the vampires, and searched for and reunited with his last brother from the orphanage all by the age of 15. Despite his troubles, he's managed to have an optimistic attitude about his life going forward, and he enjoys doing a variety of selfless and often charitable work for people, especially children - in need. All of this awarded him an eager acceptance letter from Hope's Peak Academy, along with the title: The Ultimate Survivor. His adoptive brother, Yuichiro Hyakuya, who has spent the last five years making poor grades and sucking at iaijutsu, somehow gets in too.

    ❝𝗜'𝗠 𝗦𝗢 𝗦𝗜𝗖𝗞 𝗢𝗙 𝟭𝟳, 𝗪𝗛𝗘𝗥𝗘'𝗦 𝗠𝗬 𝗙𝗨𝗖𝗞𝗜𝗡𝗚 𝗧𝗘𝗘𝗡𝗔𝗚𝗘 𝗗𝗥𝗘𝗔𝗠?❞ ━━━ 𝗧𝗢 the criminal underworld, Number 07 was the ultimate ghost-a cold, calculative, and utterly flawless apex predator with a multi-million yen bounty on her head and a trail of silent takedowns in her wake. She was engineered to be a weapon, hallowed out by handlers who saw her as nothing more than property. But after a frantic, midnight escape that left her terrifying boss permanently scarred, she ran straight into the light. ​Now? She's just (Y/N) (L/N). A sleepy, street-fashion-obsessed slacker who spent her hard-earned freedom curating the perfect early-2000s Gyaru aesthetic. ​Relegated to the mountain campus of Kunugigaoka Junior High's Class 3-E, she fits right in with the misfits and dropouts. With her heavy liquid eyeliner, signature blunt bangs, oversized beige cardigan, and ridiculously soft, fluffy faux-fur wrist cuffs, she looks completely ridiculous. She claims to hate school, actively skips homework to sleep on the roof, and spends her time dragging classmates to Shibuya sticker booths and hoarding street-side strawberry crepes. ​But you can take the girl out of the underworld, but you can't take the supercomputer out of her brain. ​Despite being the smartest person alive, her protective "big sister" switch flips whenever Class E looks at her with pleading eyes. Her tutoring methods are entirely unconventional, chaotic, and downright hilarious-dismantling complex college calculus like an assassination mission and introducing a flustered "sweet-and-headpat" reward system that drives the boys into absolute, blushing overdrive. Armed with flawless physical conditioning and a lethal center of gravity hidden beneath her slouchy brown leg warmers, she is the only student capable of executing a flawless strike on their Mach-20 alien teacher, Korosensei... even

    (Yeah, I rewrote the story) Nagisa Shiota was a high school student living with his parents in a fairly good apartment. He was the male who was in the "end class." He was the male who studied hard to get better grades. He was the male who was always the peacemaker between the rowdiest people in the class. He was the male who tried hard to reach his goals with pure vigor. And he was he male who's life hadn't truly started until a certain yellow octopus barged into their class. Right? Everything class 3-E knew about Nagisa Shiota was questioned as another transfer student was introduced to the class. "Hi, my name is Kai Shitai and I'll be joining you from now on, please treat me well!" One Kai Shitai will shift everything they thought they knew as pasts are revealed, wounds reopen, and chaos erupts. Welcome to the life of Shiota Nagisa, and join him as he is forced to look back on his dark past. Their dark past. Useless A/N you probably don't wanna read: Sorry if this is horrible and I have a lot of wrong spellings, that is bacause.....yeah, I have no excuse. As you all know assassination classroom does not belong to me, this is just a fanfic about it. I might enter in some karmagisa, nothing major though. This story will mostly be focusing on their past and all that jazz. (for all those who read this before, sorry for adding yaoi if you didn't like that but now that i've become a fujoshi I just can't suppress my urges, I actually planned to not put any yaoi at all but that miserably failed as you can see in the edited parts)

    Hiding your bloodlust is one of the most basic techniques of being an assassin. To strike them an unexpected blow. It's as simple as that. At least, that's what I've been telling myself. But this time, it's most probably not bloodlust I'm hiding. It's something else. ~~~~~~~~~~~~~~~~~~~ Another Karmagisa Fic set in high school, featuring 0 originality, a lot of Karma's weird traps, and cute Nagisa moments. Hopefully more fluff than there is smut. Written by a guy that has never actually finished assassination classroom.

With Kunigigaoka Academy's buildings on the process of renovation, where else will their students transfer to? Why, to Teiko Middle School of course!

Disclaimer: I do not own the animes Assassination Classroom and Kuroko no Basuke respectively. I exclusively own the plot, and the OCs (original characters) I include in the overall storyline.

    Devils and demons are common in the world Nagisa lives in. They, of course, are mischievous and naughty. But some of those creatures are too much. Causing danger and disturbance in the peace of the world, killing and harming innocent people. And after all of the disasters made by those annoying hell-dwellers, the government, as well as the holy angels, had enough. That's why they established an organization of agents sent to destroy the evil forces and maintain the innocent peace of Earth. And Nagisa Shiota, a little cinnamon roll, is part of the said organization. Why and how he got in are some things he want to keep to himself. And also, every "agent" need someone--or something, whatever the devils are called--to help them eliminate the evil demons. Even though he said he doesn't need one, it's a requirement so he doesn't have a choice. And very fortunately unfortunate of him, he got a redheaded devil. One that is so--I mean, so sadistic and mischievous Nagisa almost tied him up in the cellar. And so, full of encounters and uncovering secrets, the journey of Nagisa and Karma, a devil so sweet and cunning, started. ****************************** I do not own Assassination Classroom nor the characters and medias and whatsoever in this. There's also the OOCness of them and OCs. I'm really sorry I just love them. Oh. This is AU, by the way.
