THE IDOLM@STER Prologue SideM -Episode of Jupiter-

Touma Amagase, Hokuto Ijuuin and Shouta Mitarai already perform as the unit Jupiter when this prologue special picks them up, tracing how the three of them end up at 315 Production, the agency that recruits idols out of other careers. Screened ahead of the SideM television series, it puts the trio's standing and their working relationship in place before the wider 315 Production roster arrives. Haruka Amami appears from the original iDOLM@STER line, tying Jupiter's start back to the franchise they came from.
