Gust is a young girl who creates items, usually out of very strange ingredients, and sells them. She resides in Lastation, and Noire usually comes to her with her problems so Gust will give her something to make her feel better. Along with Nisa, she will join Neptune's party through the Gust Battle Ticket for $1.99. Her name is derived from Gust Corporation, who releases their games under the NIS America label. Her outfit resembles that of a character in the Atelier series produced by Gust.
She has moved from Lastation to Lowee.
She has moved from Lowee to oblivion.
Gust appears in enough chapters to count on one hand, runs a shop that Neptune buys items from, and overcharges her up the ass.
