While I'm here I should specify a few-

One of them involved a dimension-hopping girl who traveled to a school and killed a few student girls. I believe one was in a bathroom, one in a crowded cafeteria and then she has sex with another one before killing her. I believe she also kept small prizes to remember her snuffs as well.

I can't remember what it was titled, but if anyone here knows about this story and/or can find it I'd thoroughly appreciate it.

Another I can confirm as strangely missing is Consensual Genocide Run (an Undertale snuff story which I've since found posted elsewhere as well)

I just don't get it!
