As early as the anniversary celebration of Azur Lane's Chinese server, a collaboration with Atelier Yumina was announced, but the specific date for the Azur Lane and Atelier Yumina collaboration was only recently revealed. It has now been confirmed that the collaboration between Azur Lane and Atelier Yumina will officially start on July 24, 2025. This time, not only is there a new collaboration, but the previous collaborations with Atelier Ryza 2/3 will also be re-run. For more details, please see the introduction below.

The "Alchemist and the Tower of the Skies" event for this Atelier Yumina collaboration will run from July 24 to August 7, while the re-run of the Ryza collaboration will be from July 26 to August 7, delayed by 2 days, to give everyone more time to complete the former's activities.

This collaboration introduces four brand new ships: SSR Light Carrier Yumina Lisfield, SSR Light Cruiser Elara von Duller, SSR Battleship Niena Fried, and SSR Destroyer Renia. All can be obtained through limited construction, with Elara also available via activity Pt exchange.

These four new ships will also come with exclusive special armaments (exclusive weapons), and there will be new equipment obtainable through accumulated Pt, which should be similar in function and positioning to existing options, possibly with some faction-specific bonuses or special BGM effects.

The collaboration will also introduce companion skins for these four new ships. Additionally, Reisalin Stout (from the Ryza collaboration) will have a new skin, and Carla Idias will finally get a skin, as she was the only one without one during the last Ryza collaboration. There's also a new skin for Zhaohe, a pool-themed skin matching Yingrui's.

The main content of the Azur Lane and Atelier Yumina collaboration has been introduced. There are still some items that, although not part of the collaboration, will be released during the same period, such as next month's 24th World Tour basic reward "Dunkerque·META", the Special Tour reward "Montpellier new skin", and the whispers for Z52 and Golden Hind, among others, all of which will be gradually unveiled during this collaboration event. Stay tuned!
