Change Our MIRAI！ is the flagship debut single of Irodorimidori (イロドリミドリ), a Sega-produced fictional character band project conceived for the rhythm game CHUNITHM. Composed, arranged, and penned by fu_mou (of Hifumi,inc.), the track features five vocalists, each voicing one of the band's members, and surges forward at a relentless 256 BPM, matching the determined, aspirational tone of its Japanese lyrics about finding light in darkness and moving forward together. The song was added to maimai on July 16, 2015, the same day CHUNITHM first launched in Japanese arcades, serving as both a commemorative crossover and the very first Irodorimidori song to appear in any game. Its animated music video was produced by Studio TRIGGER, lending the track a visually explosive identity that complements its high-speed energy. Within maimai, Change Our MIRAI！ is distinguished as the only song in the ONGEKI & CHUNITHM category to retain both its original Standard charts (dating back to ORANGE PLUS) and a later set of DX charts (introduced in maimai でらっくす), bridging two generations of the game's charting systems across region releases including Japan, international, USA, and China.
