Do not tag futanari if there are no female genitalia present on the person in question.

Even when it was confirmed by the characters in the story that she was given that dick and turned into a futanari and its constantly mentioned?

Yes, even then. The characters in the story never actually confirmed that she still had a pussy nor is there ever any indication that she still has one (and her not starting with a penis is irrelevant, since there are many galleries where an originally normal girl is given a dick and it is clearly shown that she no longer has a pussy [and of course idiots still tag those as futanari because of course]), and the terminology used within the gallery is irrelevant from the start (especially considering many artists, and many many western artists in particular, draw obvious shemale yet refer to it as futanari all the time).
Per the tagging rules, if testicles are shown but vagina never is, use shemale for tagging. It's completely visual-based.

So this some form of Taimanin Asagi ripoff?

Not a very good translation. Seems like MTL
