–𝚿The Most Disastrous Life of Saiki Kusuo: Somehow, I Got a Family| Saiteru 𝚿– by Galaxy_Hv

Summary
Ten years after breaking the Volcano Time Loop, Saiki Kusuo is now 26 years old and has somehow ended up exactly where he never expected to be: married to Teruhashi Kokomi.
Naturally, he insists this outcome is merely the result of her Divine Luck influencing probability and absolutely not because he has grown attached to her.
Now, as a manga editor, part-time house husband, and father of two children, Saiki has to deal with new inconveniences he never prepared for: a daughter who inherited his psychic abilities and her mother's impossible luck, a son who is determined to be as normal as possible, a world-famous wife who refuses to stop overworking herself, and a family that somehow keeps making his quiet life anything but quiet.
Kuriko Saiki may be the strongest child on the planet. Satou Saiki may be the closest thing to normal in the family. Teruhashi may still be perfect in everyone's eyes.
And Saiki Kusuo may still claim he feels nothing.
Unfortunately, nobody believes him anymore.

Summary
Saiki Kusuke gives Teruhashi Kokomi a seemingly innocent present, saying that it's from his younger brother who wants nothing to do with her.
Unfortunately for Saiki Kusuo, that gift are two hairpins that cancel out all of Kusuo's powers when he tries to use them on Teruhashi... including but not limited to telepathy and x-ray vision!
Then, Aiura Mikoto discovers that Teruhashi has the mark of death! But how can Saiki continuously save her without using his powers on her while also figuring out how she really feels about him? -

Rumor has it by beasaik

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
In which an average girl wakes up to strange and loud noises in her neighborhood after a not-so-average encounter with a classmate, completely oblivious to the fact that she had just stolen something from the strongest person alive.
or

Summary
Saiki Kusuo just wants to live a normal life without anything else disrupting it. That is, until you come along. Sure, he could ignore you and act like nothing is different.

Nothing could go wrong, right?

Summary
Saiki tries to fix his reality, but something 𝚋𝚛𝚎𝚊𝚔𝚜 completely. Everything is 𝔀𝓻𝓸𝓷𝓰 and no one else notices it except him.
Slice of Life comedy where anything Saiki does backfires somehow and ao3 can not handle it.
Or.. What if Saiki meets the cast a few years earlier than in canon?

Summary
Solely someone with the exact same struggles could ever understand her. Kusuo Saiki realized that he was the only person that could possibly relate to the perfect, pretty girl's problems, and that maybe she could understand him too, which unfortunately lead to a series of crises. He didn't want to spend more time with her, he didn't want to help her more than it was necessary, he surely didn't want to attract attention to himself and most importantly, he did not want to fall in love with her. Regrettably, his name was Kusuo Saiki and he was the unluckiest boy in the world, so all the disasters were bound to happen.

Summary
I should've let it go. Really, I should have.
Instead, the question followed me all the way home.
Why couldn't I hear him?
And for the first time in a very long time, I found myself genuinely curious.
OR
Reader is a psychic and both reader and Saiki wonder why they can't read eachothers thoughts.

Summary
Saiki can’t help but stare at her as she gets lost in thought. They’re in a closet after all. There isn’t anything else interesting to look at.
But for some reason, it’s difficult for him to take his eyes away from Teruhashi’s lips. It’s strange. The closet they’re in is dimly lit, but her lips seem more vivid and inviting than ever—
Wait, what?
--
Or, Saiki lands himself at a party, and Teruhashi is there too. One bottle spin later, they're in a closet together for the next seven minutes.inspired by @luv_potatao on tiktok for terusai 7 mins in heaven spin the bottle college au!

Perfect pretty girls don't vomit out flowers because their crush doesn't like them back.

The shenanigans of adolescents from Year 3 Class 1 has reached the end of their predicted timeline, after an anticipated 4-year pause.
Out of everyone, Saiki is the most ecstatic to move on from this chapter of his life. However romance comes a-knocking on his door. Much to this psychic’s dismay.

Summary
Saiki may take notice to the color of the sky, or even the ever growing cold, but that doesn't mean he pays much attention to the little things. That being said, Kaidou's scarf is dragging.
___
A routine outing turns into a quiet show of kindness, but Saiki insists it was only a matter of problem-solving. The real problem is that the first incident wasn't the last.
