Is this Atelier stuff

Without looking I very much doubt this is in any way related to the Atelier series.

For the non-weebs... In anime circles when one speaks of Atelier, they're generally referring to the LOOOONG running series of games by Gust (now part of Koei Tecmo) that began on the PS1 with Atelier Marie: Alchemist of Salburg, an RPG in the mold of early FF or SO but with a bit more crafting emphasis. Generally speaking, Atelier games are what you'd expect of JRPGs, although the original's premise was fun (the OG Marie being a magic school flunk out alcoholic on academic probation).
