@TitanAnteus She literally has no more significance then Kobayashi's boss at this point, and you called her "family member". Her romance is just token obligatory tie-in, her connection to cast fading. She is basically in another (pretty dull) story at this point, while "Justice dragon, Takiya and Fafnir" occasionally introduce their own perspective on situation. Well, Fafnir also kinda fading with nothing to do because we basically learned his perspective at this point so he can't contribute anything anymore.
So, no unique interactions with the cast and no unique traits of her own - I don't think I owerblow things when I say she lost everything of interest.
What does "not a lesbian" (wich is confusing logic either way because of her genderswapping powers) have to do with anything? Or was it important for you?
When she was introduced she was whole new dragon with own beliefs (or lack of such) and potential, her imput to relationships, her intersecting yet opposing to Tooru's view on goals in life (romance). Now she is kinda oblivious pair of flame sacks.
