The young miss's 'three non-attributes' personality should already be quite familiar to old players. In simple terms, she is a tsundere rich lolita, standoffish and prickly, always aloof, the kind of person who will harshly scold you if you so much as utter a word she dislikes.
However, the method to improve her favorability is surprisingly simple.
My companion, Meow Meow Shark found some relics of vampires in the ruins, and after giving them to the young miss, we received her gratitude. So currently, the most effective way to boost favourability is to 'grave-dig', uh... I mean search the ruins for anything related to the Vulture Vampires.
Moreover, the young miss is a very professional psychic and good at teaching others, so if you can humbly discuss some spiritual energy issues with her, or find some spiritual energy scriptures to give her, you should be able to increase her favorability as well.
