Summary
"Just—hold still," Kurosaki breathes against my ear, and his other arm circles my waist, keeping me steady. "Sorry," he utters before his glowing eyes disappear from view, and I feel something sharp scrape the delicate skin of my neck.
Oh. I didn't see that coming.
A new transfer student has come to PK Academy, and while Saiki Kusuo tends to do his best to stay away from newcomers, his apparent friends are adamant in befriending this new guy. The only problem is that ever since Kurosaki Hiro stepped into his school, Saiki's powers hardly work as they should. Not only can he not read Kurosaki's mind, but he can't read anyone's mind the moment he's in the same vicinity as him.
To make matters worse, Kurosaki doesn't even seem to be human.
What a pain...

Summary
Kusuo's hell begins towards the end (what he thought was the end at least, lol) of an exhausting day. His health deteriorates over time as a result, as he is ditched by those closest to him, left alone to rot away as he just tries to get it all back to normal. For someone who considers himself a step up from being human on the evolution ladder, he sure is very human right now.

Summary
Saiki Kusuo was born a psychic. However, his powers didn't show up all at once. First, it was telepathy. Then he gained levitation, teleportation, etc, etc. As he grew up, he gained even more powers. Some he deemed useless, like making coffee bitter, and others he recognized as more powerful, like mind control. His powers grew daily; at this point, it wasn't surprising to discover new powers seemingly out of nowhere.
But this power, well, Saiki just had to ask if this was too powerful?
TL;DR: Saiki discovers he's immortal, and decides to change the course of human history forever (by giving people quirks).
Later, out of boredom, he joins Class 1-A, and immediately regrets it.This work is inspired by:

Summary
Saiki didn't stop running. Not when he heard Kaidou's thoughts or the delinquents taunting him for abandoning his "friend". It's not like he'd regret it. Kaidou would call him and say he made it out just fine soon... Right?
One of the more crude AU's I have. Based on Season 1 Episode 17 (Chapters 83 and 84 for Manga readers) so enjoy :3 Also sorry for being gone for so long.

Summary
There's one word Saiki Kusuo would use to describe the life he's led since college: boring. But, he would always say it was a good kind of boring, like he always wanted. But not anymore though. This boredom was easy to ignore at first, but as the years have dragged on at a snail's pace but also simultaneously distressingly quickly, one day Kusuo realises he doesn't enjoy his life anymore.
In the years since high school, our psychic has attained his dream of an ordinary life, but is it still what he wants? It's kind of boring, isn't it? After a series of frustrating events and a costly mistake, he takes the time to reflect upon this, and has an unexpected realisation.
Meanwhile, elsewhere in Japan, a woman who by all accounts was expected to have an easy life has had anything but. Betrayed by everyone, evicted by her family, about to hit her breaking point and end it all, she manages to find herself in exactly the right place and time…

Summary
(Story inspired by a song called "Smile"! If you know My Little Pony, you should know what I'm talking about... MLP was a huge part of my childhood and even though I don't associate with it now, I still do occasionally go back to memories :3)
A normal sunny afternoon, one where Saiki finally has a chance to relax and unwind. There's really nothing going on. His friends are all out with each other, there's barely anyone in his 200 meter radius, his parents are out shopping, it's finally peaceful... That is... until Kaidou bursts in, looking happier than humanly possible.

Summary
Saiki is intimately aware of how the human brain functions and all of the lows and highs that the regular person experiences, as he gets older he learns how to selectively tune it out. High school is the hardest part, he has to deal with the overwhelming thoughts of all teenage drama such as unrequited crushes, bullying, self-esteem issues, and the list goes on. He'd never admit it but he found comfort in his little group of friends, Nendou not being capable of experiencing self doubt and Kaidou's delusional fantasies keep him sane.
But as the third, and final, year of High School approaches, it slowly but surely all goes to shit.

Kaido took a step further. "We can help you! Do you really think that after knowing you for so long we'd just leave you when you need us most?"
Kusuo felt his energy falter.
"We're here for you, Saiki!" Hairo added, "We've always been, and we always will!"
"Just like you've been for us," Mera added, extending her hand towards him, "Just come with us and everything will be ok."
Kusuo's hand began to shake, his resolve to hold back any tears breaking as the pillar kept growing heavier and heavier."You're not scared to stand in front of a monster?"

Summary
Kusuo and Kokomi always had a special connection with Christmas. They both have plenty of fond memories of this holiday, so join them on a trip down memory lane, where they watch films, bake delectable goods, nearly blow up Kusuo's house, and grow closer together and to their friends. This takes place in a timeline when they were both born significantly later than in canon, but the events of their lives happened at the same ages they did originally.

Summary
Kato looks in the mirror and eyes his reflection tentatively.
His hair, usually combed back and maybe a bit oiled up if he felt like it, was a tousled mess. He pushed a few blonde strands out of his face and huffed. This is very bad. Terrible. One hundred percent despicable.
He inhaled and pressed the palm of his hand onto his forehead. Why is this happening? He shook his head side to side with a sigh. How come something that started as a dream turned into reality? Kato didn’t know.
Everything would be fine, really, if he didn’t fall for such a cliche; staying up all night and watching anime. Well, maybe it wasn’t such a cliche, considering how every reincarnated or transmigrated nobody stays up reading a manga or manwha and then turns into a medieval villainess. Kato paused, sparing a glance down at his shoes. Fuzzy slippers. He is no villainess.
—————————————————————————
Kato Arata thinks of himself as an average man. Well, he doesn’t actually remember much about himself, but he knows that he probably wasn’t all that special in his old world. But, transmigration? To a slice of life anime? The life waiting for him back home has got to be better than this.
