Hentai

In Japanese, the word hentai means metamorphosis, abnormality, or sexual perversion. It is never used to refer to "normal" sexual activity, or to adult manga or other entertainment that is merely sexually explicit. The terms 18-kin (18ç¦?, literally "18-prohibited") meaning "prohibited to those not yet 18 years old", and seijin manga (æˆ?人漫画 "adult manga") are used.
