Don't confuse and conflate the two, even if the site tags here do. Lyssa was not futa, that was Trans. Futa are magical women who have cocks appear when they need them. Lyssa is packing meat 24/7.
that's incorrect.
Trans are those who physically male who had surgery/hormones to look like women. incomplete surgery would mean they still have their cocks and balls.
Futanari is a generic japanese term for female-looking hermaphrodites. Some have both male and female genitalia, while some only have a cock and balls (so they are technically not hermaphrodites), and some have female genitalia plus a cock, depending on the creator/writer. Some have the cock on all the time, while other have their clits turning to cocks, and there's even one hentai anime where the cock came out of the vagina, making me assume it came from the uterus or it was the uterus. The cause can be magic, or science (nanites, etc.). There are many versions, they are generally treated as women with something extra.
that said vinovella games only have trans characters, no futa.
