Lucia Borthayre is a character in Atelier Lydie & Suelle: The Alchemists and the Mysterious Paintings.
She is an alchemist and only-daughter of Merveille's number one atelier, Atelier Borthayre. She is overbearing but easily gets lonely. She considers herself a tactician, however, her moves are always obvious to those around her.
Lucia is the cousin and childhood friend of Lydie and Suelle, but they have a rivalry among each other. While Lucia can be very arrogant, she is kind at heart towards her two friends. She is concerned with coming off as too mean.
Lucia is available as a playable character if you purchase her downloadable content.
