The Idolmaster SideM is breaking out of mobile screens and live stages all at once. On the second day of the franchise's 11th-anniversary live event this Sunday (13) at the Toyota Arena Tokyo, Bandai Namco confirmed the line's first-ever console game—headed to Nintendo Switch and Switch 2—alongside the theatrical release of the F@ntastic Battle Fes movie in Japanese cinemas on November 20, 2026.
What happened?
The game announcement came from D3 Publisher, a subsidiary of Bandai Namco. The title does not yet have an official name or release window. The genre is described as an 'idol production and scheduling adventure': players step into the shoes of a 315 Production producer, guiding 49 idols across 16 units toward a massive live concert set a year away.
The story is original while staying true to the official SideM universe. The promise is true console scale: more text, deeper routines, and more breathing room for each unit than the standard mobile format typically allows.
At the same event, the company confirmed the film Gekijō-ban Idolmaster SideM F@ntastic Battle Fes ~Who goes first~. It is not an original animated feature in the traditional sense; rather, it is a cinematic cut of the 2025 live concert of the same name, featuring 8 units and 25 idols. Screenings will include regular sessions and 'support' screenings where audiences can wave lightsticks, clap, and sing along. Advance tickets (Mubichike) go on sale October 16.
What does this mean?
SideM is the male-centric branch of the Idolmaster franchise. While the main series tasks players with producing female idols, this branch features an all-male cast—and its fanbase, particularly in Japan, is massive enough to justify live tours, CDs, anime, and now a full-fledged console title.
Bringing the franchise to the Switch 2 highlights its growing scale. D3 Publisher and Bandai Namco are betting that the habit of 'producing' idols translates well to Nintendo's handheld hardware, going beyond smartphones. Meanwhile, the film turns a past live concert into a cinematic product, following the established trend of recorded concert screenings used by this franchise and other virtual idol brands in Japan.
The Bottom Line
It remains unclear whether the game will feature full voice acting, how many routes each unit will have, or if a Western release is planned. What is confirmed is the scope: 16 units, 49 idols, a brand-new story, and a heavy focus on scheduling and production. Fans following SideM on mobile should expect the same strong bond with specific units, just with much more room for text and event depth.
As for the movie, it has a firm release date: November 20, 2026, in Japan, distributed by Shochiku ODS with music by Lantis. No international release has been announced yet.
