Her original design was more priestly, but was toned down for looking too much like a sentai villain. The outfit on the right is an early draft of her story mode outfit. The note on the right talks about how scary she looks with her hair down, but I don't see it.
She's only depicted playing the flute in the intro of the second game, but I'm glad that concept was there from this early on.
Just a close-up of her pretty face, yeah?
While I'm certain these are all official, I have taken them from FightersGeneration.com. They have some weird ideas about when this game takes place, though. It's in Nineties Japan, not ancient Japan. The Parking Garage stage with the audible car peel out should be a clear indicator.
