Last thing from me: google yourself for futanari! Then you will see that a character with boobs and penis doesn't make it a futa, even if it's a fantasy character. Here is an example not from wikipedia (worst source someone can come up with) but from urbandictionary:
"futanari
Also known as "futa" for short, is Japanese for hermaphrodite (-ism), or having the genitalia from both genders.
Commonly found today in hentai (anime porn), or in the "3DX" community on the internet (a community that puts original or existing 3D characters in sexual situations. They're commonly known for making 3D futa characters or futa versions of existing characters from video games), the characters are normally depicted as a humanoid female with both a penis and a vagina, while most of the time having penis lengths in the 12-18 inch range and a 2-3-1/2 inch girth (considered normal for a futa), or bigger with an equine variant, and excessive seminal output anywhere from pints to gallons.[...]"
So stop this bullshiting me. And the dev already wrote, that the MC does NOT have a vagina, ergo it can't be a futa. Even if she's born like this.
