Leblanc is a sphere hunter and the leader of the Leblanc Syndicate in Final Fantasy X-2. She is the Gullwings' rival for much of the game.
Leblanc has a round face with purple eyes and short, blonde hair. She wears a pink-purple robe that exposes her chest and the tattoo of the Leblanc Syndicate's logo as well as her right thigh. The robe has a high, curved collar with tassels, and long sleeves reminiscent of a Japanese furisode kimono, the cuffs separated from the ends of the sleeves by white criss-crossed material. She wears thigh-high stockings of the same color and purple ankle boots. Blue and white triangular and swirl patterns decorate her attire. She wields a red-and-silver fan in her right hand.
Leblanc is cocky and self-centered. She has a not-so-secret infatuation with Nooj of the Youth League, which brings out her sensitive side. In fact, Leblanc became a sphere hunter to find something from Spira's past to make her "Noojie-Woojie" smile for her. Leblanc treats outcasts kindly, having taken in those who had nowhere else to go. Logos and Ormi came to work for her after she took care of them after the events at the Den of Woe during Operation Mi'ihen. Though she abuses her subordinates, they remain at her side as they owe her for helping them out.
