I'm guessing the answer is no, but will there be any possibility of "duplofying" other characters in the future?
Hate to burst your bubble here, friend, but "duplo" (the traditional true futanari) with both female and male sex organs are RARE! The author of this story has already clearly stated that duplo are extremely uncommon. They are so rare that there is little verifiable knowledge about them leading to many myths being spread regarding duplo, branding them as outcasts to the point that poor Ashe is TERRIFIED to admit that she is, in fact, a duplo.
What you are suggesting would make the author/dev,
MorriganRae, into a liar by adding more duplo to the story. The story has been written. Duplo are exceedingly RARE. After seeing only the initial version, I can already say without hesitation or reservation that this will be one of the top futa protagonist titles ever.
Adventure ever on, Phat
