Utagoe ha Mille-Feuille, a music project featuring characters and young female voice actors, released a CD single of their third anniversary songs, “Utagoe High-Six” and “STAY GOLD,” on April 23, posting each song’s music video on their official YouTube channels.
“Utagoe High-Six” is a self-introduction song of the Temarizawa High School A Cappella Club. The original version with backing track was previously included in their first single “SINGING” released in March 2023. They have sung a cappella arrangement version in live events and concert for a long time, and that version is finally being released as a CD.
