The series focuses on the male idols of 315 Production, in contrast with the normally female idol centric series.
THE iDOLM@STER SideM was a game that featured the recruitment of soon-to-be idols at 315 Production and the three idols within the unit Jupiter, who have now defected to 315 Production. Like THE iDOLM@STER Cinderella Girls, it was a social media game hosted by Mobage.
The game's main theme was job change. All of the idols have jobs, and for various reasons, they decide to switch and become an idol. The player is the producer, who helps them achieve their dreams. There were 46 voiced idols, divided into 15 units to choose from.
