Scariest アニメ you've ever watched??

Elfen Lied..the dog scene T.T had to look away..and some other scenes like with Kouta-kun's sister Kanae-chan and so on,also Highschool of The Dead was too,but only sometimes.

I guess Ghost Hunt is scary. I didn't get scared, but people that have watched it say it's scary if あなた watch it at night.

Elfen lied was so scary. I've seen higurashi pictures and that looks even creepier

I would have to say Puella Magi Madoka Magica. It's not that it is bloody または anything, but it really messes with your mind, perception, and what あなた would do. Would あなた become a magical girl only to become the creature あなた are trying to defeat?

Higurashi no Koro ni (Kai)

Maybe Mirai Nikki
Yuno Gasai scares me. I think she's freaking and scary, and... yeah, that's all I can say ^.^

shiki is my answer...
I dont know why my little sister even watch this show
It's scare's me to DEATH!!!!
