Hello! Well, I hardly read psychological manga as you can see. But I've watched some anime. Like: Deadman wonderland, Death parade, Psycho-pass, Zankyu no terror, Paranoia agent, Ano hana, Elfen lied... as for manga I've read horror but I don't call them psychological.
Hey Pri! I'm glad you like my list (〃´∀`)... Didn't think anyone else'd ever lay eyes on it xD
Do you have any good recommendations?
