Hentai: A Japanese slang word meaning perverted or perversion. In the world of manga and anime, hentai refers to the adult oriented titles that present extreme, graphic sexual imagery. A common Western stereotype concerning manga and anime is that these artforms are filled with graphic sex. While such imagery exists (and has always existed in Japan), hentai titles make up just a small niche market in Japan's massive manga and anime output. Good examples of hentai anime would be La Blue Girl and Urotsukidoji (also see SHUNGA).

Anime: a distinctive style of animated film that has its roots in Japanese comic books, immediately recognizable and characterized by heavily stylized backgrounds, sci-fi and fantasy themes, highly exaggerated facial expressions with limited facial movement, simulation of motion through varying the background behind a static character or other foreground element, and frequently, big-headed characters with child-like, large eyes; originally called ‘Japanimation’ Examples: Princess Mononoke (1997) and Spirited Away (2001).
