'hololive Dreams' is reportedly an idol-training sim from QualiArts, the dev behind IDOLY PRIDE and Gakuen Idolmaster. People are talking about how executives from QualiArts and CyberAgent's mobile game unit suddenly followed hololive Dreams, despite rarely using their X. It’s not a rhythm game,, it sounds like the gameplay will be closer to the Idolmaster style (similar to Uma Musume or PowerPro etc).
