Summary
"It's better this way, Teruhashi-san."
That phrase kept haunting Teruhashi's mind even after all these years; it was the last thing he said before vanishing.
After Aiura's vision, Saiki had one simple rule: cut ties, and the world stays safe.Saiki did exactly that. He just didn't count on Teruhashi Kokomi waiting for him to come back anyway.
—
aka: Saiki is desperately trying not to come back, but Teruhashi doesn't know how to give up.Bookmarked by Yeonran

Summary
The internet has survived celebrity scandals, alien conspiracies, and the occasional apocalypse rumor.
But nothing could have prepared it for the possibility of Teruhashi Kokomi changing her surname after marriage.
As panic spreads across forums and every corner of the web, one question throws thousands into collective crisis:
Who should really be changing their last name?

Summary
What was supposed to be a "quiet" afternoon at Nendou's house quickly turns into a disaster when eight PK Academy students squeeze into his living room for a board game.
When a citywide blackout leaves them in the dark, someone inevitably suggests ghost stories by candlelight. Between Kaidou's Dark Reunion theories, the Occult Club's creepy tales, and a house full of idiots, Saiki realizes far too late that unlimited coffee jelly wasn't worth it.

The Caring Acts of Teruhashi K. by iridescentlavender

Summary
Post-meteor, Saiki adjusts to having his powers back.
(There’s definitely nothing else going on that he needs to adjust to. In case you were getting any ideas.)
This is pretty much all fluff, Teruhashi being nice, and Saiki examining his feelings while trying not to do exactly that.

The Disastrous Requiem of Saiki K. by suspisius_stew

Summary
His hand reached into the toxic, bleach-scented sludge and sipped it. He was engulfed in the realization of how easily he could tip over and never take another breath, until a frantic thought pierced his skull.
*No! No, Saiki, no, stop!*
Drinking that river water was a guaranteed death sentence. Caught in the act, he did the only logical thing. His eyes rolled back, and he let his body drop, collapsing completely limp onto the ground to fake a faint.
The government initiation was brutal: survive 365 days in the wasteland to earn extraction. After a year of ruthless culling that weeded out the weak, the surviving classmates are now trapped in a bunker, battling starvation, grief, and highly toxic weather. To earn their right to come back home.
To keep the camp's crumbling morale from shattering completely, Aren and Teruhashi place their most unapproachable classmate on a strict 24/7 suicide watch rotation.
What they don't know is the true nature of Saiki Kusuo's death wish. He isn't actively trying to kill himself, he just believes he doesn't deserve to live. Weighed down by a crushing secret guilt, Saiki is burning away his own energy to secretly keep them alive.

Rumor has it by beasaik
Fandoms: 斉木楠雄のΨ難 | Saiki Kusuo no Sai-nan | The Disastrous Life of Saiki K.
12 Jul 2026

Summary
Saiki Kusuo had already saved the world once.
After stopping a literal meteor, his psychic powers were back, PK Academy was as chaotic as ever, and all he wanted was a quiet afternoon with some coffee jelly.
When a misleading photograph threatens Teruhashi Kokomi's perfect reputation, one desperate lie leaves Saiki trapped in a fake relationship, surrounded by endless rumors, jealous classmates, and far more attention than any psychic should ever have to endure.
'Good grief.' He had already accepted that his life would never be ordinary. He just hadn't expected it to turn into a romantic comedy.

Summary
Ranks and such had been around as long as humans had existed. Everyone knew the roles and abilities each rank offered, and it was still the same way to this day. Well, societal influences had progressed at least.
Kusuo Saiki was not a normal human; he wasn’t even sure the ranks applied to him. They could not have enough effect on his everyday life whether he presented or not. So why bother about them, right?
Wrong.

Summary
All Kusuo wanted for his third year of high school was for it to pass by normally. Too bad he and Kokomi are going to, as they say, “kiss kiss fall in love”.
(Wait, this isn’t that kind of anime!)

aka, Saiki’s life turns into a cliche, tropey romance anime. Teruhashi’s life, on the other hand, just got a lot easier.

The Day Teruhashi Kokomi Disappeared by r3ndition
Fandoms: 斉木楠雄のΨ難 | Saiki Kusuo no Sai-nan | The Disastrous Life of Saiki K.

Summary
Teruhashi Kokomi had always been the perfect pretty girl. If water freezing at 0°C was a fact of science, then Teruhashi's beauty and charisma was a fact of life—no, of existence. Since the day she was born, people constantly tripped over themselves to fulfill her every whim. No matter the fact that she was only 16; men of every age revered her.
To Teruhashi, this was simply the natural order of things. If she was God's favourite, then of course everyone would adore her! Coddled her entire life, she never had to lift a finger.
That is, until the morning she woke up looking completely, horrifyingly ordinary.

Teruhashi x Saiki Swap AU
Teruhashi/Evil Saiki
— — —
It’s just another day for the perfect girl, Kokomi Teruhashi. Beautiful, kind, helpful… and psychic. She can read minds, see the future, move objects without touching them, and has made it her goal to make everyone’s life just a little bit better.
Naturally, she’s the most popular girl at P.K. Academy. But when a new transfer student arrives--Kusuo Saiki, quiet, annoyingly indifferent, and possibly… evil?—Teruhashi finds herself facing a problem she can’t simply fix with a flick of her wrist.
As her psychic powers reveal more of a force darker than she expected, she realizes this “mysterious new boy” might just be the one challenge she’s never been prepared for.
Teruhashi must wrangle her way through love, danger, and powers beyond her imagination that all culminate in her very high school… where the perfect girl might be in over her head.

Summary
Saiki Kusuo miscalculated. Just slightly. He made a very minor lapse in judgement by poorly assessing the amount of energy he had left.
Hence why he was falling out of the sky.

Summary
Aiura has always been confident in her powers, and rightfully so- they've never been wrong! So when her powers tell her that Kusuo Saiki is her fated partner, she believes it wholeheartedly, zero nuance required.

Before anyone says "this is out of character, Aiura would never" I will remind you that she canonically tried to sexually assault him in chapter 186 so this is actually TONED DOWN from the way she canonically is.- Language:

Summary
Once it had passed, Saiki gave his son a once-over, checking for any injuries or discomfort. There was nothing. Kusei looked at him with bleary eyes, and now that he was securely in his father's arms, went promptly back to sleep.
Saiki deadpanned internally. He had almost pulverised the plane. Good grief. Better not think about that for now.
__________________________
Aka: Saiki's disastrous life continues even in his thirties, now with a (perfect) wife and a baby, who was starting to develop the same overpowered tendencies as his father.

I Can Hear Your Thoughts, Kokomi by marurei

Summary
When Saiki Kusuo and Kokomi Teruhashi are paired together for a photography assignment in their media class, they have the chance to spend time (alone) together after school.
Kokomi struggles to keep up her perfect persona, Saiki discovers his affection for her because of her imperfections that only he knows about. He wants to confess his feelings, but that wouldn't be right if she doesn't know the 'real' him. Their friendship explodes when he confesses that he's been able to read her mind the entire time."A wave of internal groaning washes through me. Not that I care. Well, I do, but not the way she imagines. I care because this assignment could have been over in twenty minutes with Kaido or Nendou, but now it’s going to be four hours of performative normalcy with the school’s #1 sneaky social engineer. There’s a hitch in Teruhashi’s step, a hint of triumphant confidence before she glides over and takes the seat beside me. Her perfume smells like strawberries, or at least the synthetic idea of strawberries; too sweet, zero nutritional value."
