Have you check 'An Oasis Gilded in White Silver [Youjo Senki x Cyberpunk][Pre-Edgerunners/2077]' fic yet ? It very good so far and also show another side of Tanya that most tanya fic tend to not touch at (as a maker, not just being another leader-salesman). Which show clear in chapter 4.b there, it also another one where Tanya grow up properly instead of "forewer loli".
