Objectively, Lana is the best sister.
>Good with animals, knows how to care for them
>Good with cars and plumbing, incredibly helpful
>Might be messy, but she has shown she can be perfectly tidy to the point of actually winning a pageant
>Took very little time to pick their loved ones' needs instead of pursuing her dreams, still has the opportunity to work in the big leagues when she grows up
Also I like the name and her voice is nice, but that's subjective.
