Shouldn't have said that now I'm curious lol
If you want to see young girls get physically and emotionally brutalized then it sure is the manga/anime for you otherwise I'd steer clear.
Yeah, I'd really recommend against looking into it unless nothing fazes you. There are some things you just can't unsee. It was pretty popular among anime fans when it came out, and I figured everyone had most likely seen it or knew about it. That said, it was literally the first thing that came to mind when I saw those arrows floating around the MC in this story, and even more when they started actually making contact with her.
