Are the Starlights really male or female?
The obvious choice is that they are male and change to female, but there are two manga references which suggest otherwise (but are ambiguous). First, Princess Fireball asked the Starlights why they chose “this appearance”, and they responded that it was easier to find women that way. Some have interpreted it to mean that they chose to be male, although it could also refer to their singing career. Second, in manga #16, page 165-166, Tin Nyanko tells Usagi not to trust those who are female but dress up as guys. Although obviously referring to the Starlights, she is not really in a position to know much about them.
