THE IDOLM@STER Prologue SideM -Episode of Jupiter- is the first episode of THE IDOLM@STER: SideM anime series. It was aired on September 30, 2017.


The male idol unit, Jupiter, dominated the idol industry under 961 Productions. However, they became fed up with the way that the company's president, Takao Kuroi, handled business and decided to defect from the company to manage themselves. Along with the helpful live house staff, the three idols always try their best to fulfill their fan's expectations despite their hectic schedules. However, after a year of their solo activities, the president of 315 Production, Takashi Saito, comes to scout them. While they decline him at first due to their bitter experiences with previous scouters, they decide to take him up on the offer after realizing that they've forgotten about their fans' feelings.
