Hello, there is currently one Futa in the game, and a second one will be arriving in an upcoming update. Both will have their dedicated scenes, but they are not the main protagonists.

The main protagonist is not a Futa but a man.

One of the two (the one currently in the game) will have a dedicated ending. Which means multiple scenes and a developed story/romance.

If all you are interested in is the Futa content, I recommend waiting a bit before purchasing the game, as I wouldn't want you to be disappointed.

Even though for the moment, among all the LIs, the Futa's scene is the most hardcore.
