Here's some information we don't usually see publicized before a game releases. Atelier Lulua: The Scion of Arland artist Mel Kishida has given some insight into the characters of the game by sharing their ages. While the characters don't have a specific age documented, they do have age ranges.
The characters in the image above, from left to right, are Rorona, Totori, and Meruru.
- Rorona is between 35 to 39-years-old
- Totori is in her 20s
- Meruru is about the age of a college student
