Pre-registrations are still on-going, with the game getting an updated release window for sometime Spring 2023. You can do so by following the official game Twitter and subscribing to the official Youtube channel for up to 10 draws in the gacha as well as a “sound card” (presumably the game’s equipment system) up for grabs. Mika Nakashima will be performing the game’s theme, SYMPHONIA, as composed by rionos. The game itself has seen some changes, with a graphical update to 3D to “keep up with the times” as it’s said.
Two new characters were shown off, featuring “Pomp and Circumstance Marches No.1 Op.39-1” voiced by Tachibana Hina, and “Erlkönig D.328” voiced by Tojo Hisako.
As for the takt op closed beta, that is currently scheduled for December 2022, with more news to follow. As it happens, the Destiny anime adaptation Blu-ray discs will include an item code for use in the mobile game. Destiny will likewise see a manga adaptation, this time from Anna’s point of view.
Another livestream regarding the game / series is planned for November, which is likely to reveal more about the closed beta, besides other related projects.
