10 Anime Series All Horror Fans Need To Watch

This show isn't for the squeamish.

Adapted from the 2011 manga series, Tokyo Ghoul takes place in an alternate universe where Ghouls, who look like humans themselves, blend into society while feeding on the human populace to survive. They're feared by the general population and hunted by investigators from the Commission of Counter Ghoul (CCG).

The story focuses on Ken Kaneki, an ordinary human who has an unfortunate encounter with a female Ghoul known as Binge Eater. Barely escaping with his life, he recovers only to discover he's become a half-Ghoul through an organ transplant.

Kaneki's personality experiences dramatic and unstable changes throughout the series. He goes from a kind and quiet bookworm to a brutal, merciless fighter who suffers from bouts of insanity due to cannibalizing other Ghouls to gain more power. In one fight in particular, he completely loses it and starts talking to himself. It's disturbing to watch...but it's also terrifying and exciting at the same time.
