The anime world covers a big range of topics, and probably most people — those who never went too deep in the anime world — tend to think that anime are merely aimed at children, or teenagers. Yet, those who have always watched anime throughout their life, and therefore got the chance to explore the anime world fully, are able to realize that some shows are definitely not for kids. In fact, some anime may contain obscure, and complex themes that are obviously aimed at — and enjoyed by — adults; some other shows may have adult content, such as nudity, scenes of graphic violence, and so on. In this list, we tried to include mature shows particularly enjoyed by an older audience, and whose themes are better understood, and appreciated by adults. We're talking about anime with a solid plot, in-depth analysis of the characters, and sprinkle of sex, emotional distress, and even gore.
