Revue Starlight ReLive
For those interested in this series, A-Team recently released the game for the series on Google Play and Apple App Store. It is basically like a sequel to the series with many new characters and stories.
Those who start it can claim all 9 original stage girls among other rewards, including enough gems to do the redo summon which guarantees a 4-star unit and can give up to 4 other 3 star units. This redo summon will only be available until April 23, I think it was and costs 3000 gems.
t is an RPG style game, rather than rhythm, like what would be expected and can be rather addictive.
