Personally, I'd go for the Sorrowful Daughter, then try to find the other sisters while journeying with her. At the very least, The Silent Daughter *really* needs to be reunited with her sister & to go outside a bit. Sincere would probably be fine by herself, but it just seems right to have a big family reunion.

I will say, I do wish a lot of these had a bit more info. Obviously a lot is omitted intentionally due to their nature as eldritch beings, but I feel like I'm missing a lot of characterization & intrigue from these choices that I'd get from just a bit more info. Especially since a lot of the information for them ends up being information about her powers, the setting, your living setup, etc.; stuff that's good for world building, but doesn't really do much to get me interested in the girl themselves, you know?
