Yuna, Final Fantasy X-2

The woman in the photograph is dressed in a costume reminiscent of Yuna from Final Fantasy X-2, with a distinctive white dress adorned with pink accents and a brown belt. Her hair is styled in loose waves and she wears a necklace featuring a blue gemstone. She holds a gun in her right hand, which appears to be a prop rather than an actual firearm. The background of the image is blurred, but it seems to feature colorful lights or decorations, possibly from a convention or cosplay event. Overall, the woman's costume and pose suggest that she is cosplaying as Yuna, and the image captures her confidence and enthusiasm for the character.
