Said to be the daughter of the Fleuret Family from the country of Tenebrae, Stella Nox Fleuret is an enemy to Noctis Lucis Caelum, although her allegiances are unclear. She is ladylike and polite but is direct in her manner, acting according to her beliefs. Her weapon of choice is a rapier which she can summon from a golden rune similar to Noctis and his sword.
Breath-taking cosplay by ~RinoaMao! Fans of Final Fantasy Versus XIII might recall this very similar screenshot from the game. Great work by photographers Saikit and Henry and stylist Maria. Thanks to the cosplayer for this awesome contribution!
