Momoiro Clover Z has announced that they will digitally release their new song "Mnemosyne" on May 1.

"Mnemosyne" is described as a bright, nostalgic summer song themed around "the memories of summer." Its jacket artwork features seasonal motifs such as ice cream, sunflowers, and swim rings.

The lyrics and composition were handled by invisible manners, who previously worked on Momoiro Clover Z songs, including "Xiao Yi Xiao!," "The Diamond Four," and "MYSTERION."

A pre-add / pre-save campaign began on streaming services on April 23. Fans who reserve the song through participating platforms will have it automatically added to their library on its release day.
