Yostar announced on both the English and Japanese Azur Lane social media accounts that an Atelier Yumia crossover is on the way. There is no release window for the event. However, every account did confirm that there will be updates on this collaboration soon.
This crossover notice only appeared on the Yostar accounts. The Koei Tecmo ones didn’t mention it. This suggests the Atelier Yumia crossover will only be limited to the game Azur Lane. This happened when Atelier Ryza appeared in the gacha game in 2022 too.
Thinking back to that event does offer hints as to what we can expect from this upcoming Atelier Yumia crossover. Six characters from the Atelier Ryza trilogy appeared as ships when that happened. In addition to Reisalin “Ryza” Stout, Kala Ideas, Klaudia Valentz, Lila Decyrus, Patricia Abelheim, and Serri Glaus.
The Atelier Yumia event is one of many collaborations with other titles to show up in the game. For example, Azur Lane hosted characters from DOA Venus Vacation, The Idolmaster, and Senran Kagura.
As for Atelier Yumia, the two major crossover events for it previously involved Tales of Graces f Remastered and Tekken 8. Yumia ended up with costumes because of both of those.
Azur Lane is on mobile devices. Atelier Yumia: The Alchemist of Memories and the Envisioned Land is on the Switch, PS4, PS5, Xbox One, Xbox Series X, and PC.
