A mobile gacha game based on the Sakura Taisen series. Features a brand new cast in an alternate timeline from the rest of the series, and predominantly features mecha musume instead of the series' trademark steampunk mecha.
The game launched on December 12, 2020 and ended service on June 30, 2021. Hololive's Houshou Marine and Shirakami Fubuki were slated to do voice work for new original characters, but the collaboration was canceled due to the game's premature closure.
