I think it’s a bit dumb that this goddess is all about how everything is beautiful but the avatar is still a beautiful woman in the traditional sense. I think it would’ve been more poignant for her to be old, or crippled, or something like that.
@Multitules step siblings don't share a blood connection. It's mostly if a parent marries someone else who already has children. Because they share the same father they're half siblings
@tigerstar186 Actually, since she's the goddess of beauty, no matter what she looks like that would be the norm of beauty (don't forget that beauty isn't a constant, but something that change in different place and at different times)
But since explaining that no matter what she look like, people that look like her are beautiful and those that doesn't are ugly. Making her pleasant looking for us is easier
