IDOL ULTIMATE ONCE AND FOR ALL Reveals Three Shows, Idol Lineups and Ticket Details

765 PRODUCTION × 961 PRODUCTION IDOL ULTIMATE ONCE AND FOR ALL has received its first major wave of details since the project was announced in July 2026. The full official site opened on September 6, 2026, confirming three separate performances at KEIO ARENA TOKYO on July 24–25, 2027, along with idol lineups, individual show times, ticket categories and the first advance lottery.

A newly revealed key visual places Haruka Amami alongside Touma Amagase, reinforcing the event's concept of two competing “ideals” represented by 765 PRODUCTION and 961 PRODUCTION. The three shows also feature distinctly different rosters, ranging from Miki Hoshii, Takane Shijou, Kohaku Okuzora, Leon, Shika and Aya to the wider 765 lineup and the three members of Jupiter.

765 vs 961, Official Teaser and Key Visual

Three Performances Feature Different Concepts and Rosters

Rather than running two days around one repeated lineup, IDOL ULTIMATE ONCE AND FOR ALL is structured as three separately titled performances with different idol combinations.

The first, TO:STARLIT OF PROMISE, begins at 6:00 PM on July 24. Its currently announced lineup consists of Miki Hoshii, Takane Shijou, Hibiki Ganaha, Kohaku Okuzora, Leon, Shika and Aya. The official site still includes “and more,” meaning its roster is not yet final.

The second performance, BE:STELLA OF ABSOLUTE, begins at 12:00 PM on July 25 according to the official event site. Chihaya Kisaragi, Yayoi Takatsuki, Ritsuko Akizuki, Azusa Miura, Iori Minase, Makoto Kikuchi, Ami Futami, Mami Futami, Leon and Shika are listed.

That same day concludes with IF:THE DAY OF JUDGMENT at 6:00 PM, featuring Haruka, Chihaya, Yukiho, Miki, Takane, Hibiki, Touma, Hokuto and Shota.

Haruka and Touma Lead the New Key Visual

The key visual released alongside the full website places Haruka Amami and Touma Amagase together in a single composition.

Both are also part of the third performance, IF:THE DAY OF JUDGMENT. Touma is joined there by Hokuto Ijuuin and Shota Mitarai, confirming all three members of Jupiter for that show.

The pairing of Haruka and Touma also sharpens the event's official promotional premise: 765 PRODUCTION and 961 PRODUCTION represent two ideals that once pursued the same dream, took different paths and now collide after crossing years of history and rivalry.

Bandai Namco has not yet explained the complete narrative structure connecting the three shows, leaving the exact relationship between their individual titles open for future information.

TO:STARLIT OF PROMISE Brings Together Kohaku, Leon, Shika and Aya

The first performance stands apart from the other two by pairing Miki, Takane and Hibiki with Kohaku Okuzora, alongside Leon, Shika and Aya.

Kohaku and Aya played major roles in THE IDOLM@STER STARLIT SEASON, while Leon and Shika have appeared across earlier console-era Idolmaster projects.

The current “and more” label is important because it confirms that additional idols may still be revealed for the first performance.

No details have been announced regarding performance order, special units, collaboration songs or how each idol will be positioned within the xR show's story.

BE:STELLA OF ABSOLUTE Pairs Eight 765 Idols With Leon and Shika

The second show features Chihaya, Yayoi, Ritsuko, Azusa, Iori, Makoto, Ami and Mami, with Leon and Shika joining the roster.

With eight classic 765 idols concentrated in one performance, BE:STELLA OF ABSOLUTE currently has the strongest 765-focused lineup of the three announced shows.

The official website presently lists 11:00 AM doors and a 12:00 PM start. Some initial secondary reporting listed a different time, but this article follows the current first-party schedule.

The setlist and any unique conceptual differences separating BE:STELLA OF ABSOLUTE from the other performances remain unannounced.

IF:THE DAY OF JUDGMENT Brings Haruka and Jupiter Together

The third performance features one of the event's most striking combinations: Haruka Amami and several 765 idols share the lineup with Touma Amagase, Hokuto Ijuuin and Shota Mitarai.

The three are collectively known as Jupiter, giving IF:THE DAY OF JUDGMENT a particularly strong connection to one of the franchise's long-running 765-versus-rival dynamics.

Haruka and Touma, who headline the new visual, are both part of this performance, making the third show appear especially central to the event's “ideal versus ideal” presentation.

However, Bandai Namco has not announced whether the live will directly follow the continuity of any specific game or instead use an original xR scenario.

Tickets Are Split Into 765 Production and 961 Production Seats

A distinctive part of the ticket structure is the choice between a 765 Production Seat and a 961 Production Seat.

Regular tickets for one performance cost ¥12,000, while the limited-goods version is ¥18,000 per show.

Three-performance packages with limited goods are available for ¥54,000 for either production choice. The bonus item is the PRODUCTION ALLEGIANCE LIGHTTAG, with different designs depending on both the performance and selected production seat.

The first advance lottery opened at 12:00 PM JST on September 6, 2026 for 12-month ASOBI STORE Premium members and runs through October 28 at 11:59 PM. Lottery results are scheduled for November 16 at 1:00 PM.

The Dress Code Extends the Production Rivalry to the Audience

The 765-versus-961 concept also extends beyond the stage and ticket names.

The official site sets a dress code of “an item representing your production affiliation.” Attendees are encouraged to wear something that identifies the production they support, although the site frames this as a request to participate where reasonably possible.

That makes 765 or 961 affiliation part of the audience experience and directly complements the two production-seat categories and corresponding LIGHTTAG designs.

Whether the selected production will affect interactive elements, staging or any live-specific outcomes has not been announced.

IDOL ULTIMATE Revives a Long-Running Idolmaster Term

The name IDOL ULTIMATE itself has history within the franchise.

In THE IDOLM@STER 2, “IU,” or Idol Ultimate, appeared as an important competition for the idols. The PlayStation 3 version also used an IU victory as the objective of its Ryugu Komachi-focused Extra Episode.

The 2027 live directly uses the same terminology, but Bandai Namco has not stated whether the old competition structure will literally be recreated on stage.

Its use therefore provides strong franchise context without confirming that the new xR event shares the same canonical rules or story.

Why This Matters

1) 765 vs 961 is built into the event's actual structure

The lineups, production seats, LIGHTTAG bonuses, dress code and promotional slogan all turn the rivalry into more than a marketing subtitle.

2) The three performances appear designed to offer different dynamics

TO:STARLIT OF PROMISE, BE:STELLA OF ABSOLUTE and IF:THE DAY OF JUDGMENT each have their own lineups instead of repeating one identical roster.

3) Jupiter returns in a strongly 765-and-961-themed event

Touma, Hokuto and Shota appear together in the third performance, while Haruka and Touma also lead the newly released visual.

4) The IDOL ULTIMATE name connects the new live to the games' history

IU has existed as a franchise term since earlier Idolmaster games, giving the 2027 project a clear nostalgic layer without requiring the older storyline to be recreated literally.

Closing

IDOL ULTIMATE ONCE AND FOR ALL has now evolved from a 765-versus-961 teaser into a much more clearly structured xR project, built around three separate performances, different rosters, production-specific ticket categories and an audience dress code.

Several major elements remain unrevealed, including the setlists, additional first-show idols, the xR narrative structure, the complete merchandise lineup and potential streaming plans. Those details will determine how far the 765-versus-961 concept extends into the actual July 2027 performances.
