Tokyo 7th Sisters

~ the goodbye ~
The premise is dated 2034. A legendary idol group called the Seventh Sisters broke up suddenly in 2032, and two years on you are appointed manager of Nanastar, a new studio in a Tokyo that has quietly concluded idols were a thing people used to care about. Your job is to walk the city looking for girls nobody else is looking for, against a general opinion that the format is finished.
Donuts Co. Ltd. put it on iOS on 19 February 2014, with the Android build following on 13 November. Victor Entertainment handled the music, and that single fact explains most of what followed. This was a rhythm and idol-raising game with more than fifty fully voiced characters and a recording budget behind them, which made it a music business wearing a game as a storefront.
Japanese idol gacha is a category I have no standing in. It is sold in Japanese and built around concerts you would need to be in Tokyo to attend, and the handful of English-speaking players who kept up did it through an unofficial information account rather than any official channel. What travels across that distance is the arithmetic: twelve years and five months of daily operation on a codebase started in 2014.

~ the fiction and the calendar ~
A game about an idol revival, set twenty years ahead of its own launch, turned off eight years before the year it was set in. The staff who wrote 2034 in 2014 were picking a date far enough out to feel like science fiction. It has since become a date the product will not see.
The story was also about exactly this: a city that had moved on from a format, and a studio trying to prove the format still worked. Holding that argument open for twelve years is a long run by any measure, and it is still a reasonable argument to be having. The thing making it is what stopped.
~ three months and five days ~
The announcement came on 7 May 2026 and fixed the closing date at 12 August, leaving players three months and five days. The reason given was the changing development environment in the mobile game market. The phrase covers a lot of ground, and underneath it sits an ordinary problem: an app built for 2014 phones needs continuous re-engineering to keep launching on current hardware, and at some point the re-engineering costs more than the remaining players bring in.
The game had just passed its twelfth anniversary. Closures that arrive right after an anniversary tend to mean the decision was made before the celebration and the celebration was allowed to happen anyway.
~ what continues ~
An offline version was promised so that the story and the music stay reachable without a server. That is the standard arrangement now and it preserves roughly what you would expect, which is everything except a reason to launch it on an ordinary Tuesday.
The unusual part is what did not stop. Live events continue. Merchandise continues. The characters came with voice actors and their own discographies, and there is a 77-minute animated film from February 2021. None of that needed the app to exist. Most dead gacha games take their franchise down with them because the game was the only place the franchise lived. Here the game was the part that wore out first, and the concerts kept their dates.
