Lostmilia.

 (ろすとみりあ. ) was an idol group formed on February 28, 2022 from former members of Seka moment and utatane.

They stopped activities in October 2022 due to Yuzuki Shiori and Nanase's Mari's departure, and presumably disbanded later that month after Utsuki Mina decided to leave the group as well.
