Please do every female character in Final Fantasy and how to tell them apart from each other 😭

Something that bothers me a lot about FFX-2 is that it never truly clarifies whether or not Yuna is a "pop star". Of course, the game opens with a concert wherein she is the main attraction, but it turns out that was Leblanc, not Yuna. But why would Leblanc pose as Yuna here?

Sad it doesn't include the protagonists from any of the Final Fantasy games I've played.
