On March 16, Ms.OOJA released her digital single "FLY," which is part one of her seven-month consecutive digital single release project. 

To commemorate 10 years since her major debut, Ms.OOJA will be holding her very first Budokan concert on March 27, 2022. Like her last song "Hajimari no Toki," "FLY" was co-written by producer Ryosuke "Dr.R" Sakai and singer-songwriter Rung Hyang. It's a message song that encourages people who are taking a new step forward this spring.

In addition, the music video for "FLY" has been uploaded onto YouTube. It was created by Craves, a visual creator from Athens, Greece.
