>Higana calls Shigana, who travels with her, her "daughter." The reason for this is never directly stated, so we can only imagine, but it does seem as though she is thinking of someone else when she sees Shigana. Could there have been another person named Shigana in the past?
>Is she a "daughter" related to her by blood, or is it an analogy of being "pretty like a daughter"?
