Summary
This is a rewrite of a story I posted a while ago. I wasn't happy with how the original turned out. When you read it, it feels rushed and kind of messy, so I decided to give it another shot.
Class 3-E finds out that Nagisa had a boyfriend, and let's just say they did not see it coming. They’re shocked, a little weirded out, and, honestly, kind of glad it ended, but what no one realizes is that Nagisa never got over him. Now, those feelings are returning, whether he wants them to or not.

Summary
A Deku as Nagisa crossover fic.
His lessons on hiding the truth were from the Japanese Government itself who asked a bunch of middle schoolers not to even tell their parents that they were being trained to kill, regardless of how many times they almost got killed in return. In fact, Nagisa was still lying to his classmates at UA about that, and they got paid ten billion yen to ensure that they never talked to anyone about their third year in middle school. So why was the past slipping out? Will his classmates find out what secret's he is hiding?
Mostly focusing on the bonds between the children with some bigger events coming in. :)

Summary
"Korosensei, why is there a child sleeping in the teacher's lounge?"
An odd question made more odd when you learn that this is the classroom of assassins. The unusual situation being discussed easily, as though this wasn't a random child, but a question on a test.
Harry Potter, the unknown hero of the Wizarding World, was never treated kindly by his aunt and uncle. One day he found himself living what must be a dream: He was being beaten by Vernon as usual when he found himself in a forest he had never seen before with a giant, yellow creature that seemed to control the scenery.
-----
Is Harry the only Wix in class 3-E? Can he help them achieve their goals? Does he still have to face the same destiny as he would before?

Summary
A hotel to redeem the sinners of hell so they can get to heaven sounds like a stupid, but the 28 assassins taught by the moon destroying giant yellow octopus are more than used to the impossible.
3-E are Overlords, though most think they're a group of 3, each of them working together for their communal goal of a livable version of hell. If heaven scorns them and the hotel they choose to help and support, well... Aren't the End Class used to that? They were the scum of society after all. So who is better placed to help Charlie's naive plan?

Summary
Korosensei whisks into the classroom, eyes flinging to the still-glowing device in the corner. “Terasaka-kun, you called–?”
His voice cracks in his throat as his gaze hooks onto the wriggling bundle of clothes. Four wide-eyed faces full with baby-fat stare up at him.
“So,” Terasaka says with a strained grin as a four-year-old Itona pokes Korosensei’s tentacles, “I can explain.”
Terasaka would like to make it completely clear that he was against the time machine from the start. He would also like to make it completely clear that any situation wherein he’s been assigned the voice of reason is one guaranteed to go to shit.
So, for once, none of this is his fault. His friends have been turned into versions of themselves from ten years ago and he just wants them back, but now he's stuck babysitting them.

Summary
"I'm very sorry, Asano-kun. Please accept this apology on behalf of Karma." He straightened up and gave a small, nervous smile, his bright blue eyes meeting Asano's.
For a moment, Asano froze. His sharp, calculating mind, which was usually so fast, seemed to stutter. The sight of Nagisa smiling at him like that made his chest feel... strange. Warm, even. He quickly cleared his throat and looked away, his ears slightly pink.A story about how Asano and Nagisa developed feelings for each other.

Summary
Ability, Quirk, and Visions.
One is considered normal, one is prejudiced against and the other remains in the shadows.
Care to take a guess on which is which?
OR
U.A and Teyvat Akademy decide to perform an exchange program - Class 1-A are determined, woefully unaware as to what lies ahead, whereas the T.A students are either laughing or crying (both with malicious intent). What all students are (somewhat) unaware of, however, is that Yokohoma has a card up its sleeve.
Things get a tinnnyyyyy bit trickier when a group of quirkless students join 1-A on their trip, but it'll all be okay!!!!!! Class 1-A will totally be okay with a group of skilled assasins and a duo of too-clever detectives. Totally.
OR
I really like U.A bashing and crossover fics, and I have wayyyy too many ideas for OC inserts.

Summary
Nagisa remembered his parent’s divorce. He remembered the fighting, the crazy look in his mother’s eyes. He remembered the court room fight over which parent should look after him. Which parent cared more. Which parent LOVED him more. Nagisa remembered thinking that they were fighting for the sake of fighting. They only wanted him because the other did. He remembered deciding he didn’t want either of them. But no one asks what the child wants. No one cared about what will happen to him. No one LOVED him for him. They only ever LOVED the idea of him.
