Does anyone know what Corpse Party is about? I'm curious but worried it'll just be depressing.

well,the manga is about a girl who,well,her parents died hoặc something like that and so she lived in a,well,a big places,i don't remember much,a girl school hoặc something?and that night she come down some place,following someone hoặc not i don't remember.and someone,well um.....do bad things to her(when the one who attacked her and take her eye off i stopped)-and i feel creepy when i write that.I'm not sure if it's the real Corpse Party manga but...oh well....
the anime is thêm real i guess,a girl transfer away and in the night at the beginning of the anime nine students stay late at school and tell a horror story,then a girl take a peace of paper that looks like a body out and tell them to do as what she said.then they all rip it and she đã đưa ý kiến they have to keep it as a proof of their friendship.then an earthquake come and they all got black.When they woke up they're in a school,like a elementary school,just like in the horror story that was told about their school.And so creepy things happen and all died.I'm not enough Công chúa tóc xù to watch all
