Futanari is a term originating from Japan, used in anime, manga, and related fan art to characterize characters who possess both male and female sexual characteristics. Often, these characters are depicted in a highly stylized, fantastical manner, reflecting the boundary-pushing nature of many manga and anime works.
As a genre, 'futanari' can range from lighthearted and playful to serious and explicit, allowing for exploration of gender and sexuality in a different, imaginative context.
