This was a requested character so I don't have much to say about them as they appear in Kingdom Hearts.(I played FF:X a long time ago though.)
The default outfit(The only included outfit) is a bit difficult to break away from and keep the other elements like the ponytail and hair tube but it can be done.
The dataset was pretty low-rez so using Adetailer on the faces is recommended.
Prompt for Outfit: yuna_gullwing, hair_tubes, winged_hair_tube_ornament, armlet, hair_ornament, blue_miniskirt, blouse, showgirl_skirt, knee_boots, heterochromia, ponytail
FYI: Generating PG-13 plus images of this character will probably trip the filter. A few of my bikini/underwear examples images got nuked.
Side note: I do take informal requests(basically a bounty that you don't have to pony up buzz for) if I like the idea(Tips are nice but not required since if it's a good idea then I'll get generation Buzz). Just leave a comment on one of my models or DM me. (Comments are preferred since that let's other people see that I'm actually fulfilling informal requests.) DMs are perfectly acceptable if your request is a bit out there and needs some image examples or something.
