Filly Dee is a character appearing in Atelier Totori: The Adventurer of Arland and Atelier Meruru: The Apprentice of Arland. She is the timid and shy younger sister of Esty Dee. She is easily intimidated by people who are scary looking or have serious personalities, like Rufus, Sterk, and even Mimi. She has a distinct interest in forbidden love, especially girl/girl relationships and often fantasises scenarios out loud, much to the chagrin of those within earshot.
