Yumenosaki Private Academy is an all-male idol training course that has a long history of producing talented idols. In Ensemble Stars!, you are a second-year transfer student at this school, and you have been chosen to be the very first student of the brand-new producer course!
Once the Ensemble Stars! school year ends and many students graduate, Ensemble Stars!! begins. The idols you've produced—including those who've graduated and those still attending Yumenosaki—join an entertainment agency aggregate known as Ensemble Square, and they must learn to forge their own path in the vast world of entertainment!
Ensemble Stars! (あんさんぶるスターズ！) is a multimedia project. Ensemble Stars! was originally released as a Japanese mobile idol training game on May 1st, 2015. Starting March 9th, 2020, the app will be renamed Ensemble Stars!!, marking the start of a new story arc.
Regarding the Ensemble Stars!! update
On March 9th, 2020, the current Ensemble Stars! app will receive a major update, at which point it will be renamed to Ensemble Stars!! Basic. This app will retain all current user data and continue to be an idol training app, as usual. This update will include UI changes and some additional features, and will include new Ensemble Stars!! content going forward (stories, gacha, events, cards, etc).
Ensemble Stars!! Basic will also have access to old Ensemble Stars! content (revival events, past gacha, past backgrounds, etc). Anything that is released before Basic comes out will be considered "old" Ensemble Stars! content.
Additionally, also on March 9th, 2020, a second app will be released called Ensemble Stars!! Music, which will be a rhythm game. Basic and Music games will exist on separate servers and will not allow users to transfer or link accounts between apps, but both apps will feature the same Ensemble Stars!! content (stories, gacha, events, cards, etc). However, Ensemble Stars!! Music will not allow users to access old Ensemble Stars! content.
