It's been announced that Little Glee Monster member Serina will be taking a long-term break. 

Serina resumed her activities last June after going on hiatus in December of 2020 to receive treatment for bipolar disorder and ADHD. She participated in the group's tour 'Little Glee Monster Live Tour 2020→2021 >BRIGHT NEW WORLD<,' which ran until December 21, but after this tour, her health began to decline. As such, the group's 'Little Glee Monster ~BRIGHT NEW WORLD PARTY 2022~' concerts on January 5 and 6 at Nakano Sun Plaza Hall were cancelled. After numerous discussions with the members and staff, Serina decided to prioritize her health and focus on recuperating.

Little Glee Monster are set to release their new song, which was recorded with the five members. From now on, live performances and media appearances will be held with Karen, MAYU, manaka, and Asahi.
