Summary
Iason's eyes wandered around his surroundings until his eyes stopped on a black figure standing in the middle of the cold, lonely room. He was like a stain on a palette, a black ink in the middle of a paper sheet, something that didn’t fit in yet took everyone else’s attention hostage regardless.
Iason finds his "dead" husband in front his office room one day.
He takes it... well? -

Summary
A boy with pink hair and green glasses had been spotted flying up to the rock, one TV camera zooming right into him as he approached it, and getting overexposed by the blinding flash that occurred when he collided with it. Another camera followed him out of sight… bloodied and injured.
That boy was Saiki Kusuo. All his life, he had tried to hide his psychic powers from those around him so he could appear normal and keep them safe. His abilities were impossibly strong, so much so he needed limiting devices to poke into his head to keep them in check. He had tried to get rid of those powers, but the attempt was unsuccessful, and they appeared to reawaken when the news broke about the meteorite. He took off to destroy it and save the world…
and it had destroyed him.
Saiki dies when he stops the meteorite, and the world descends into chaos at the revelation of psychics. His friends struggle to deal with the loss, some more than others.
One boy, who's managed to escape the madness despite possessing abilities of his own, thinks he has a way to bring Saiki back…

Summary
Just months after the Multiverse mayhem, Sonic and his friends face a new threat: an alien titan burdened by power, scars, and a story none of them are ready for.
Disclaimer: The series "Sonic's Green Hills Adventures" doesn't belong to me. None of the human OC characters belong to me and I don't deserve any credit for the creation of them, MarinMelody is the creator of them and deserves all the credit. Go check it out MarinaMelody (https://archiveofourown.org/series/4011130) and read the other 5 seasons or listen to them on her YouTube channel (https://www.youtube.com/@MarinaMelody-sw1ck)
Note (written 5/3/26): Revisions of chapters 1-12 are complete, so I will start working on new chapters. The overall structure of the chapters is that same, just a few scenes have been written to add more to the chapters.

Summary
Saiki Kusuo had never experienced romantic interest- heck, interest in human beings was already rare enough until he found the most perfect person. Someone who the most common name, someone who has perfectly average scores and an underwhelmingly NOT outstanding life, Satou Hitoshi. What will Saiki do with this newfound interest?

“Eh?? Does my buddy Hairo know I'm…upset..? I thought I did my best to hide it…I’m just supposed to be the funny one…! The one people can rely on to make them laugh!” Nendou pondered before quickly concealing it with a grin.”Yeah! Of course I’m ready for it!” Nendou answered.

Summary
Ever heard of the rule of threes? Why not make that a reality in The Disastrous Life of Saiki K where now there’s a youngest sibling that’s learned a lot from their older brother. Now at the cursed school that is PK Academy, it’s mid-year and there’s a new student! Gosh, nothing can go wrong here, right?
AKA
A post-canon self insert story, LOL. A good mix of originality in the world of Saiki K with some canon characters (other than the Saikis, eventually). How cooked are they?

Summary
Saiki stared at the ceiling above him. The fan softly whistled its tune though it sometimes stopped in a violent screech through the rust. His window was opened too, the curtains floated in the vernal wind and let some sunrays in, it fell on his face, burned his irises. Yet he stayed still, lethargic on his white sheets that the more he stayed pale and laid
He wondered when it all went wrong. When it all started to shift, when his heart began to skip a beat at the thought of Kuboyasu. But he didn’t want answers, only questions which would hang themselves on his tongue, a rope of saliva strangling them to death. Maybe he will forget about it tomorrow.
But as for now…OR Saiki catches feeling for Kuboyasu, but he doesn’t know how to love and nor how to deal with it. Soul navigation ensues

Teruhashi can't understand why Saiki won't fall for her already especially after the near death experience caused by the meteor. I mean who wouldn't be shocked after that.

Summary
“Hello. My name is Saiki Kusuo.
And I am a psychic.
While that may have been alarming to say beforehand, now, currently, in the future, it does not matter as much anymore.
By that, I mean it is no longer a secret.”Got really bored and was getting tired of constantly rewatching Saiki K so I made my own content about Post-Canon that will never be canon
I didn’t know what to put as a summary can you tell -

Summary
ー〔previously called Mind Unread〕
You'd have never thought that clicking a scam ad out of boredom and curiosity could lead you to live a new and unpredictable life in another universe.
However, being given a mission to "thaw a cold heart" wasn't on your roster at all.
Who is this cold-hearted one, you might ask? That's up to you to figure it out.

Summary
☆✶∙∙∙𝟁∙∙∙✶☆
It's your third year of study at Tokyo University, your first year as an upperclassman pursuing the degree you've always dreamed of. The past two years were largely uneventful, to say the least, and you were hoping the last two would follow suit well enough for you to fly completely under the radar.
Well, any chance of that happening goes down the drain when you meet a pink-haired psychic with the same dream, followed by his tropey gaggle of 'nuisances.'
