I have watched the anime around five times XD I don't find it scary anymore, but the effects and art style is just amazing. The manga is really good, (blood covered, not musume) but only 36 chapters are translated at the moment
Oh, I thought this was about Cannibal Corpse. Yeah, I don't watch cartoons much anymore. Rather just play video games. gotta get dat dark elf level 75.
The anime scared me. My friend who told me about it recommended I turn off the lights and watch it in the dark. Sure enough, I was grossed out. But since I love anime, I stayed through the 4 episodes.
