I've been trying my hardest to find contact the author on a few different social media sites with no luck so I've decided to just upload the edit. I WILL TAKE THIS DOWN IF THE ORIGINAL AUTHOR WANTS/TELLS ME TO!! all credit for the original fic goes to the original author (should be tagged above.. somewhere...)

Summary
Saiki sees a bug while with his "friends", Nendo and Kaidou, and accidentally teleports the three of them to the My Hero Academia universe. They get mistaken for the transfer students that were supposed to arrive that day, and basically just all bond with class 1A as they go through training and even some villain fights (dark reunion??!!). This is mostly just going to be a fun little fanfic, but it'll get more serious/developed as I go on. (this is my first fic I've written and im not also the best writer so please go easy on me!!)

Summary
Kuusuke still remembers that day. That stupid, stupid day.
He still wishes he could've done something. As a genius, a son, and most importantly a big brother, maybe he could've saved him. Maybe he could've been a better person to his brother.
But now, as the fog in his twisted mind starts to clear, it's already too late.
Saiki Kusuo is dead.
OR: An AU where Kusuo never went to PK Academy.
PLEASE give me criticism, PLEASE.

Summary
For the four years that you have attended PK Academy, you never acknowledged Saiki Kusuo as anything more than a friend. However, with the passing time, you become more and more curious about the man. What lures you in? Whether it be the bubbling tension between the two of you, or the lingering glances, or even just the air of understanding.
You want to know him.
And unlike others, he does not mind knowing you.
Maybe there is a hint of sweetness under those layers of mystery.
[In which-you and saiki begin to notice each other more and more until it leads to something more than friendship] -

Summary
(REVISED)
You had never seen your life before your early consciousness, before you could walk on land, you just never expected your life would be like that at not you remembered after all this time.
You were something unique before, you were with something or someone unique with your liking.
Something that changed your title and your being.
The very man that changed you, colored out your true side and revealed yourself without you even knowing about it ‘till now. The moment you met him, you hadn’t exactly expected a lot of twists and conflicts would appear and thrive back. But you’d hope this particular Psychic would get to stay in your life, even when your own world is different from his.
Completely Different.

Summary
It started out simple, he was just doing errands for him mom. He's not quite sure when it turned into this. . .
Or in other words: Saiki Kusuo is a brat and likes messing with Teruhashi a little too much. I mean she can't get everything she wants all the time right?

Summary
After everything that had happened, you'd think Saiki would be done. Saving the world twice was enough. And years went by just as he had hoped, just as they always had. He'd rather not have his powers, but they persisted. He worked around them like usual.
And yet, here he was, stuck in the middle of a world where his only means of getting home was to solve everybody's problems, including his own, whilst dealing with a sudden bounty over his head. Fuck his life.
His name was Kusuo Saiki, and he was apparently a therapist now. And a weapon of warfare. -
Psychics Are Sorcerers, The Literate Are Wizards -- Argue With The Wall by arumwithabuckethat

Summary
Tsukiko Kayo, who serves their inmate time for their second year at PK Academy, stumbles upon well-intent acquaintances AKA their classmates. Orphaned but not famished, they live alone in an apartment and value their lonely space much wisely. Kayo isn't psychic but her written or oral compositions grab people's attention, therefore skill over gift.
That is until they meet a comparable outcast (outside of psychic abilities) named Saiki Kusuo. So much for self-focus.
Kayo gets intuition solely from her dreams, is that supposed to be a supernatural attribute?What a nuisance.
Or
Two atypically depressed people meet. What could possibly go wrong? Saiki fears for the worst.
Skip to chapter two if you don't want to read the first 2.7k words prior to an actual Saiki dialogue.
This fanfic is supposed to be a polar-opposite of the majority fanfics under Saiki Kusuo & OC and Saiki Kusuo/OC where the reader or OC is always bubbly and family-oriented.
Has been edited numerous times because I keep making mistakes. Specifically, I messed up the timelines when writing chapters 1 & 2 but they're fixed now.

Summary
There are some brothers—friends to an extent—that seem to hold a grudge against your entire soul. The catch? They’re absolutely in the right, and you’re absolutely in the wrong to even say such things.
Unless, maybe this time, you stop blaming them and start searching for them instead?
OR: The author's study of feelings that are just so wrong to be real, and it just happened to be set in the Saiki K universe.
