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
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.

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.

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.

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.

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.
