Idol Group AQA to End Its Current Lineup at the December 8 Zephyr Hall Show as Ria Shirahane, Au Amai and Miru Rairi Graduate

日本語版を読む →

Not a breakup. “The end of the current lineup.” When an underground idol group reaches for that particular phrasing, there is almost always a next chapter waiting behind it. AQA is no exception.

AQA will close out its current lineup with a show at Zephyr Hall on Tuesday, December 8, 2026. Ria Shirahane, Au Amai and Miru Rairi are graduating, while Nodoka Yumesaki, Yuika Tsubame and Uyu Himeno carry on under a new lineup. Six becomes three, and the next phase starts from there.

The debut show for that new lineup lands three days later, on Friday, December 11, at the same Zephyr Hall. The room where it ends and the room where it begins are the same room, and that detail hits harder than it has any right to.

This article lays out the date of the final show for the current lineup, which three members are leaving and which three are staying, what is happening at the December 8 performance, and when the new lineup gets its unveiling.

When does AQA’s current lineup end? The December 8 Zephyr Hall show is the last one

AQA’s current lineup ends with the group’s performance at Zephyr Hall in Tokyo on Tuesday, December 8, 2026. The group itself is not disappearing; this is a line in the sand drawn on the assumption that AQA continues with a different roster.

Full details for both shows will be announced separately. In other words, what is locked in right now is the dates, the venue, and the framework of who stays and who goes.

Who is graduating? Ria Shirahane, Au Amai and Miru Rairi

The three graduating members are Ria Shirahane, Au Amai and Miru Rairi. Of those three, Miru Rairi is also leaving her management agency.

Spelling out the agency departure as well means fans have been told plainly that they will not be running into her at the next show. The three who remain, meanwhile, stay signed and move straight into the new lineup, so the day-to-day operation of the group carries over unchanged. This is exactly the part announcements usually leave deliberately vague, and AQA has separated it out cleanly.

Will the December 8 show feature the full lineup?

Yes. Au Amai, who has been on hiatus, will take part in the December 8 show, and the full lineup will perform two songs together.

That said, Au Amai is only appearing for those two songs. She is not on stage for the whole set, so it is worth calibrating expectations here. Building a two-song slot so a member on hiatus can stand on that final stage reads as a practical compromise that still respects how fans feel about it. Knowing there is a guaranteed window where all six are together is a big deal for a farewell show.

…And a “just two songs” setup like this is precisely the kind of thing that wrecks a battle-worn fan like me.

When does the new lineup start? An unveiling on December 11 at the same venue

The new lineup gets its debut show on Friday, December 11, 2026, at Zephyr Hall. That is two clear days after the final show for the current lineup.

The tightness of that gap has to be deliberate. Announce a lineup change and then go quiet for a few months, and the heat at the shows cools off, taking a slice of the audience with it for good. Put the new lineup on the same stage three days later, and anyone who showed up on December 8 books the 11th in the same breath. It is a schedule designed to squeeze every bit of continuity out of the three members who are staying. Details for both shows will be announced separately, so that is also when to check how ticketing is being handled.

Summary: the six-member era ends December 8, and a three-member lineup starts on the 11th

AQA ends its current lineup with the Zephyr Hall show on Tuesday, December 8, 2026. The graduating members are Ria Shirahane, Au Amai and Miru Rairi, with Miru Rairi also leaving her management agency. Nodoka Yumesaki, Yuika Tsubame and Uyu Himeno continue in the new lineup.

Au Amai, currently on hiatus, joins the December 8 show, where the full lineup performs two songs together (her appearance is limited to those two songs). The new lineup debuts on Friday, December 11, at the same Zephyr Hall. Details for both shows will be announced separately.
