I'm not very familiar with goth culture, but i think
this one has such a character. Problem is, let's just say interacting with the character doesn't keep her "trad" for long, though I think you can keep her intact instead to react to all the other TFs.
The sis in
ZR might apply too, I don't know, looks pretty minimalistic to me.
Oh, and
this may have one with a lot of content, but it's female-MC.
L&P has one too that should fit the bill well with some content, though not early on in the game.
