Atelier Ryza 2: Lost Legends and the Secret Fairy appears on Australian Classification Board
A rating classification for Atelier Ryza 2: Lost Legends and the Secret Fairy has appeared on the Australian Classification Board, filed by Koei Tecmo Europe. It looks to be a sequel to Atelier Ryza: Ever Darkness & the Secret Hideout, but has not yet been officially announced.
It's hard to say for sure based on a title alone, but it looks like its follow-up game may be the rare case where the follow-up game stars the same protagonist. Perhaps the appearance on an English board also indicates plans for a simultaneous release worldwide, which would be the first for the series. We'll have to wait for an official announcement.
