User Recommendations for Tokyo Ghoul

Both anime are extremely gory and both ask the existential question: what makes us man or monster? The ghouls and diclonius both are very similar to humans and are able to somewhat fit in society. Both main characters have back protrusions that act as weapons that allow them to kill. The main characters are also taken in by a family of sorts and taken care of. There are many interventions by the government to capture and kill the main characters.

Both include different races of people who suffer (in the exact same what Toyko Ghoul's ghouls do.) Government forces and large amounts of gore. Elfen Lied dives deeper into morality though.

Let's see; over-the-top levels of gore. A protagonist who gets broken horribly. Psychotic, yet sympathetic characters. Themes of dehumanization. Intertwining of violence and sexuality. Overall, a heartbreaking and tear-jerking story. All of these describe Elfen Lied and Tokyo Ghoul pretty well.

Gore and edgy with human-like species
