Just caught up with a phenomenal Jujutsu Kaisen whump fic and holy shit, I highly recommend it. It's nearly done, but it didn't end on a cliffhanger, so you can enjoy it as is.
It's called Abnormalize (by @suzu-kun22), and it's about a medical facility run by Sukuna and Kenjaku, where they "acquire" children with magic/sorcery abilities and put them through horrific tests and experiments for research. I say "acquire" because the kids are usually sold to the institute by their own families out of fear.
The experiments aren't necessarily graphic; they're not like removing organs or whatever, but they ARE violent. What grips me is how well the author describes pain and panic. I had to pause so many times while reading it.
My favorite part of the fic (and why I was able to get through such a heavy subject matter) was the relationship dynamics between the characters. There's a few ships implied, but it's pretty much a Gen fic in that it doesn't focus on (light) romance until much later. It does have a ton of Found Family, which I love.
I generally don't read a lot of whump (whump is basically "everything bad happens to this character") because it can often be gratuitous and heavy-handed, but that's not the case here, plus the warm moments in this fic are worth the horrors. Do heed the tags, though, especially because these kids are truly being abused here, in the name of "science".
If you read it, let me know what you think, PLEASE 🙏🏼
