One of the nice things about the Atelier subseries whose installments unfold in the same setting over the course of several years is that we get to see characters grow and change.
An interesting example of this is Filly, sister of Esty. She’s completely off-screen in Atelier Rorona: The Alchemist of Arland, puts in her first public appearance in Atelier Totori: The Adventurer of Arland and really comes into her own throughout Atelier Meruru: The Apprentice of Arland. (At the time of writing, I don’t know if she appears in Atelier Lulua: The Scion of Arland, but I wouldn’t be surprised to see her show up.)
Let’s take a closer look at this character and her role in the ongoing saga of Arland.
