About me: Short for hentai seiyoku, it originally meant any
unusual (“henâ€) perversion. The term
was popularized in Japanese psych journals in the
early 1900s and then co-opted by perverse magazine
authors. It’s important to note that hentai
does not describe a genre in Japanese like it does
in English. In Japan, pornorgraphy is normally
donated as eromanga, or adult manga.
