SideM Announces Its First Console Game and a New Film

The Idolmaster SideM performers pose at Toyota Arena Tokyo after the 11th Stage event.

The Idolmaster SideM has announced its first home console game and a new theatrical film, giving the long-running idol project two major new ways to reach fans.

The announcements arrived on September 13, 2026, in the official recap of the second day of THE IDOLM@STER SideM 11th STAGE: EVER EVER@FTER. The same update covers a film built from the franchise's live-performance culture and a separate game project for Nintendo hardware. It is a substantial expansion of SideM's current event and music ecosystem, but the details international fans are most likely to need—release regions, localization, and a game launch window—are not confirmed yet.

What Was Announced

The first announcement is The Idolmaster SideM F@NTASTIC BATTLE FES: Who Goes First, a theatrical film connected to the 315 Production presents F@NTASTIC BATTLE FES: Who Goes First live events held in Makuhari in October 2025 and Osaka in November 2025. According to the official SideM portal, the film brings the energy of those performances back to theaters, featuring eight units and 25 idols. The portal published the film overview, ticket information, and a trailer on September 13, and lists November 20, 2026 as the film's opening date.

This is not a new television anime announcement. It is a cinema presentation of SideM's performance-driven storytelling, centered on stage action and the characters' idol identities. That distinction matters when looking for screening information: the announcement concerns a film release, not a streaming premiere or a new season.

The second announcement is the first home console game project in The Idolmaster SideM's history. The official update says the project is in development for both Nintendo Switch 2 and Nintendo Switch. An official teaser video has also been published on the Idolmaster YouTube channel. The announcement does not yet name the game, give it a genre, set a release date or window, describe its gameplay systems, or confirm whether it will be sold digitally, physically, or both. The official notice also cautions that the footage is from development and may differ from the final product.

Why It Matters

SideM has always been built around the idea of producing male idols, but fans encounter that idea through several connected formats: character stories, songs, live events, voice performances, and merchandise. The film announcement makes a major live event available as a theatrical experience. That could give fans who missed the 2025 performances another way to engage with the same stage-centered material, while also turning a live-event archive into a scheduled cinema release.

The console project is the more structural change. The official wording identifies it as SideM's first home console project, so it opens a new platform path for the brand rather than announcing another mobile update or stage production. A console release could make SideM easier to discover for players who prefer dedicated hardware, and it may create room for a different kind of rhythm, story, or management experience. Those possibilities are editorial analysis, not announced features: until the project receives a title and fuller description, fans should not assume that it will resemble any particular The Idolmaster game.

Together, the announcements also show how closely SideM's music and narrative projects remain connected. The film revisits a live performance, while the game expands the brand into an interactive format. That combination may broaden the ways audiences follow the idols, but the official post does not claim a shared story, a crossover between the two projects, or a release schedule that links them.

Context for International Fans

The immediate confirmed date is November 20, 2026 for the film's opening. The official announcement is published through the Japanese Idolmaster portal and does not provide an overseas theater list, an English-language ticket page, or a later streaming plan. International fans should therefore treat the date as a confirmed announcement date for the project, not as proof that screenings will be available in every country. Regional theater listings, subtitles, and any international distribution would need separate confirmation from the official film page or a local distributor.

The game has slightly more platform information but just as many unanswered regional questions. Nintendo Switch 2 and Nintendo Switch are the only confirmed platforms in the announcement. There is no stated release window, price, age rating, language support, storefront region, or overseas publisher information. A listing on a global Nintendo eShop, an English website, or an international account would be meaningful new confirmation; none of those details should be inferred from the teaser alone.

For fans outside Japan, the practical approach is to follow the official SideM portal and Idolmaster YouTube channel, and to check the dedicated film page when ticket and screening details are updated. Fans planning around the November date should also remember that a Japanese cinema opening may not translate to the same calendar date elsewhere, even before local distribution is confirmed.

What Happens Next

The next official checkpoints are concrete. First, the film project page should clarify participating theaters, ticket sales, and whether any overseas screening or later digital distribution will be announced. Second, the SideM game project needs a formal title, release timing, gameplay details, and localization information. Third, the official YouTube channel and SideM portal are the places to watch for follow-up footage or platform notices. SideM also has a separate live event, F@NTASTIC BATTLE FES: Wanna Step In, scheduled for December 26–27, 2026 in Nagano and January 23–24, 2027 in Makuhari; that event is a future stage project, not a replacement for the newly announced film or game.

Until those updates arrive, the confirmed news is already significant: SideM is moving its live-performance history into theaters and beginning its first dedicated home-console project, while leaving the international release details open.
