Glad you like the game! You have options to customize who becomes a futa at the start of the game out of the six starting protagonists (all six characters, only the player, or only the five other protagonists). Once you reach the first adventure, doing a side-quest (you will know who's the character related to it) will unlock transformation options, which allows you to change the genitals of any character simulated at the Passion Temple.
