Fujii Seia Bids Farewell: Another Chapter Closes for Imouto Sisters
On March 31, Fujii Seia, former member of the idol group Andoll, announced her departure from the agency she had been with for over six years. She shared the news in the usual way—posting an image with text instead of writing directly in the tweet, a common workaround for the platform’s character limits.

What caught my attention was that someone asked her in English what the statement said, and she actually responded with an English translation. Lol, this is the first time I’ve seen that happen.
The next day, Seia posted a farewell message with a simple matane (またね, “see you” in Japanese) along with a couple of photos. Not long after, she made her account private and deleted several tweets, signaling her withdrawal from the public eye.
The Repeating Pattern in Imouto Sisters
Andoll officially disbanded in February, and, as expected, its long-time members soon followed suit. This cycle is nothing new for the Imouto Sisters label—when a group disbands, its members often leave shortly after. Andoll is just the latest in a long line of groups to meet the same fate.
In fact, this seems like a good time to update the list of groups that have debuted and disappeared under Imouto Sisters:
- Lily of the Valley – Formed in August 2018, disbanded in August 2024 (6 years).
- Lupinus (ルピナス) – Formed on April 1, 2021, debuted on May 9, 2021, and disbanded on March 19, 2022 (less than a year).
- Novice² – Debuted on January 29, 2022, and disbanded on April 9, 2023 (1 year and 2 months).
- Charping (ちゃーぴんグッ) – Debuted on March 12, 2022, and announced their disbandment at the end of March 2024 (2 years).
- Andoll – Debuted on May 5, 2023, and disbanded in February 2025 (less than 2 years).
As of now, there are no active groups left under Imouto Sisters. Even the Imouto Sisters Osaka Twitter account has been set to private. Meanwhile, the Imouto Sisters Tokyo account remains active, still promoting a few girls active as idols—though without an official group attached to the name.
Will We See Fujii Seia Again?
That’s hard to say. Many former members of these groups have resurfaced under new agencies and projects. At the very least, Seia chose to say matane instead of sayonara, leaving the door open for a possible return.
In this ever-shifting idol world, only time will tell if we’ll see her on stage again.
For now, I’d love to track down what the other former members are up to, but first, I need to organize all the information. Stay tuned!
