The Idolmaster: Cinderella Girls shut down on March 30, 2023, but Bandai Namco will help players keep memories of the game alive with merchandise. As thanks for eleven years of support, Bandai Namco decided to create the The Idolmaster: Cinderella Girls Complete Book. The title is a work in progress.
The book will contain all of the illustrations and text that were in The Idolmaster: Cinderella Girls. It’s basically the whole game in book format, but minus the gameplay. Bandai Namco is still developing it, so it’s unclear how many pages it will have and the price. More information on all of those details, along with the release window, will come out some time in the future via the official Cinderella Girls Twitter account.
The Idolmaster: Cinderella Girls debuted in November 2011 as the first mobile title in the The Idolmaster franchise. At its conclusion, it had over 190 idols and 90 of them had voices. Though not the same game, the rhythm game spin-off of Cinderella Girls, Starlight Stage, is still available on mobile devices in Japan.
Bandai Namco will release a book to commemorate The Idolmaster: Cinderella Girls. It will announce more details on the project some time in the future.
