Idolish7 Twelve Fantasia! [Limited Edition]

Twelve Fantasia is set in-between the story events of Parts 2 and 3 of the i7 mobile game main story. While you don't necessarily need to be familiar with the events of Parts 1 and 2, it's certainly helpful to be familiar with them.

Gameplay is fairly straightforward - set up your idols' schedules, raise their stats, then have them perform a live (which is where the rhythm game part comes in) to gain fans! The character interactions are great for fans of the franchise, and I definitely recommend it!
