Tokyo Ghoul, Yuri Kuma Arashi Recommendations
They have creatures that try to blend into the human society, but feast on human flesh. There's lots, and I mean lots of drama. They make you feel bad for them (the bears and ghouls). They also have that psychological aspect that makes you really think. The differences is that there's less war and action in Yuri Kuma Arashi, and no shoujo ai whatsoever in Tokyo Ghoul.
