"A girl who opens a mass production shop in Kirchen Bell. She's an alchemist like Sophie, but her ability is to duplicate objects. However, using her ability causes her body to shrink as a toll, so she tries not to overuse it. She's a very easygoing person who lives life at her own pace. She decides to become famous to find her father, who she has never known, and currently runs a warehouse store."
Corneria is a playable party member and owns a shop where the player can register items and ask her to auto-refill used items. As the player gets to know her better, she will decrease her fees and eventually provide her service for free.
Sophie helps her repair a music box that plays the melody of a song from another country. Logy recognizes the melody and points her in the right direction to find her father's homeland. However, in the end, Corneria decides to stay in Kirchen Bell and expand her shop so that its fame may one day reach the ears of her father.
