A demographic term for media targeted at adult men. Seinen series often have more mature, complex, and darker themes.
In-Depth Explanation
Unlike Shounen, Seinen anime can feature graphic violence, complex psychology, and sometimes explicit sex. Many non-hentai Seinen series are "ecchi" and contain nudity. Hentai with a strong "Plot" or "Horror" elements share traits with the Seinen demographic.
