Blood galore.

The concept that the parasites (almost always) take over their hosts by eating their host's head and manipulating their body might be found very disturbing. Even more disturbing is that although parasites are probably capable of ingesting human food, they specialize in cannibalism and usually leave behind grotesque and mangled remains. The main character is, however, not insane, is a relatively good role model.

Gotou is very disturbing in appearance, personality, and brutality.

Uragami holds Satomi hostage and threatens to kill her for no reason. This scene is very intense.
