Summary
Jin had many regrets but he does his best for his son, that was until his past came to bite him in the ass.
Yuuji doesn't know who his mother was or why his father was so tight-lipped about it but his answer may come in a centuries-old cursed finger he just so happened to swallow.
Gojo was curious, the two were an enigma and he can't help but want to know more about them. The boy who held and controlled the King of Curses and the man who seemed to see through Gojo yet Gojo could barely make sense of him at all.
(An au where Jin survives.)

Summary
"What? are you for real? A mental shutdown."
"What? are you for real? A mental shutdown.""Its the truth."
"Its the truth."Wait. What?
"To a person, though? That's gotta be a joke-"
A strong sense of deja vu hit him.
It's nothing. It must be. Akira pinched the bridge of his nose to stave off the oncoming headache, trying to convince himself that it's the lack of sleep. He took out his phone in hopes to find some sort of distraction until something caught his eye.
He noticed an app, red and awfully familiar
why was it so familiardespite knowing he had never downloaded it, and out of curiosity, clicked it.Nothing happened.
~~~
A New Game+ where Akira’s decisions are influenced (whether intentionally or not) by an influx of scattered memories from a past life he has no idea about. And the metaverse has changed, for the better or worse.

Summary
A supernatural investigation gone right by Itadori and Kugisaki but totally wrong for Fushiguro.
Fushiguro, an unwilling volunteer to Itadori's and Kugisaki's schemes and ridiculous plans, had decided that summoning demons that don't exist was the least problematic thing the two could do, even if he did have to sacrifice his bedroom and sleep to do so.
So when they truly do succeed in actually summoning the devil himself it quickly became the worst thing the two could have possibly done because not only was Fushiguro bonded to the devil by blood but the devil just so happened to be his missing father of 10 years.
Fuck.

Summary
Severus Snape finds a time turner, and, against his better judgement, uses it to travel back in time. Just a few hours, so no harm done, right?
Except, he found himself transported to 1933??
He meets a strangely familiar boy of the name Tom Riddle and, despite the odds, forms a rather interesting relationship with the kid.
And when Severus returns to the present, he sees this child in one Harry Potter, and an unlikely bond forms between the two.

Summary
The Pauper becomes the Prince; the Prince becomes the Master.
or: Severus is done with wizards for good. Following the death of his father shortly after his graduation, he packs his bags and sets off for London, striving to become something his father (along with every wizard from his past) would have hated. Through a series of rather unexpected events (a few chance encounters and several regrettable fashion choices), he becomes a muggle rockstar. He is the Punk Prince, lead of a rising post-punk rock band riding the new wave of the 80s. The band explodes into the British music scene, attracting fans, friends, and enemies- including those from his past.
After a Death Eater attack at one of his performances, Severus is dragged back into the world he tried so hard to leave behind. Soon Severus is caught between a prophecy, the world he's come to love, and one that refuses to forget him. He must make a choice: muggle or wizard, coward or hero, prince or master.- Language:

Summary
Harry kills his Defense Against the Dark Arts professor at the end of 1st year. Somehow, this leads to him traveling through time to the year 1971 and being dropped, alone, into an abandoned house in Cokeworth. He has only himself to rely on, as always, but there is a silver lining: he gets to meet a younger version of his mother, who is apparently best friends with a young Professor Snape. Unbelievable.
Featuring: Everybody's childhood trauma, a lot of pining, and hopefully, eventually, a happy ending :)

Summary
This one would be the easiest. In the first round, he could slip by unnoticed, all he had to do was fake it a little at the start and then run when no one was watching.
or
Yes, it’s the typical Omegaverse race scene. I’m weak for the drama, don’t judge me.
