As part of the いちかのBEMANI投票選抜戦2019 (Ichika no BEMANI touhyou senbatsusen 2019) event, players could unlock vote tickets by playing select BEMANI games to unlock new songs for each game as well as special MANIFEST rewards based on cumulative player voting. For Dancerush Stardom, the rewards all revolved around the identity of a then-unnamed white rabbit mascot and unlocking a special song for said character. After successfully passing the vote thresholds, the white rabbit's name was revealed to be "MOTTIE" in a livestream on December 1, 2019. Afterwards, "MY NAME IS", a theme song for MOTTIE, was released as an Extra Stage for the game later that month with a custom background video (another MANIFEST goal).
